Index at Acceptance:-Class 61, K( 1: 3 A: 4 C: 4 D 1: 4 D 6: 4 D 1 OC). International Classification -A 46 c. COMPLETE SPECIFICATION Device for Locking Handles to Implements I, JOSEPH JOHN MCCRI Ni K, a citizen of the United States of America, of 16 Moore Terrace, West Orange, New Jersey, United States of America, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to attachment for implements, and particularly to an attachment for locking the handle of a brush to its head. An object of this invention is to provide a device for locking the handle of a broom or other implement which has a handle connected to a head of one type or another, the locking device being inexpensive and effective to prevent the handle from becoming loose or from being separated from the implement head. A further object of this invention is to provide an attachment for a broom or the like, wherein the same fastens very securely to the handle of the broom, making it virtually impossible to turn without destroying the handle, and which clamps firmly to the head of the broom in such manner that the handle together with the attachment cannot be rotated with respect to the brush head and cannot be separated in any other way. These together with other objects and advantages which will become

subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which: Figure 1 is a perspective view of a brush fragment to which the invention has been applied; Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1 and in the direction of the arrows; Figure 3 is a top view of a blank from which the attachment has been formed; Figure 4 is a fragmentary top view of alPrice 3 s 6 d l brush having a modified form of the invention applied thereto; Figure 5 is a transverse sectional view taken on the line 5-5 of Figure 4 and in the direction of the arrows; 50 Figure 6 is a top view of another modification of the invention showing the same applied to a fragmentary part of a brush head; Figure 7 is a transverse sectional view taken substantially on the line 7-7 of Figure 6 and 55 in the direction of the arrows; Figure 8 is a plan view of another modification illustrated; Figure 9 is an enlarged sectional view taken on the plane of line 9-9 of Figure 8 and in the 60 direction of the arrows; and Figure 10 is a perspective view of yet another form of the brush attachment. In the accompanying drawings, there is a brush 10 fragmentarily shown, this brush 65 including a brush head 12 having bristles 14 and a cap 16 Threaded apertures 18 and 20 are formed in the brush cap 16 in order to accept and hold the brush handle 22, the latter having a threaded end 24 engageable with the 70 threads in apertures 20 and 18, as is customarily done. The attachment 26 which is on the handle 22 and the head 12, consists of a clamp together with means connected with the clamp for 75 fastening to the brush head 12 In the embodiment of Figures 1-3, the clamp consists of flap legs 28 and 30 which are spaced from each other and joined together at their ends by means of a flat panel 32 The general configuration 80 of the clamp is U-shaped, and legs 28 and 30 have openings 31 and 33 in them through which the handle 22 is adapted to pass These openings are slightly larger than the handle diameter, and one leg 28 is inclined a very 85 slight amount from the generally parallel position with respect to leg 30 Accordingly, when the attachment 26 is placed on the broom handle, the handle may be caused to bind against the walls of the openings 31 and 33 90 2 -), -L by tightening the screw 34 which is passed through an aperture in the panel 32 The screw has an eye 36 at its outer end so that it may be hung, thereby hanging the entire broom, f and it has a nut 38 on its shank held captive between the legs 28 and 30 As is described tightening of the screw 34 brings it to bear against and in engagement with the handle 22, thereby firmly clamping the attachment to the

handle. A strip 40 extends from the end of leg 30 and is made of flat metal stock This strip is arranged at a slight angle to the plane of the leg and has a substantially flat portion 42 which bears against a surface of the brush head 12 between aperture 20 and a corner 44 of the brush head An angulated portion 46 extends from the flat portion 42 and is adapted to come to bear against the corner 44 of the brush head 12 In this way, the device is clamped firmly to the broom Even if the handle 22 were not threaded in the aperture 20, it would be very difficult to rotate the handle inasmuch as the angulated portion 46 of the strip 40 has sufficient width to prevent such rotation. Viewing Figure 2, it is apparent that rotation of handle 22 about its longitudinal axis and with respect to head 12 will merely bring the edges of angulated portion 46 more firmly against the corner 44 of the brush head. The body of the attachment 26, that is, all parts except the screw 34 and nut 38, may be made from a single blank 50, the latter being preferably of a reasonably malleable metal. Initially, the openings 31 and 33 together with the opening through which screw 34 passes are stamped in the blank 50 Then, the legs 28 and 30 together with panel 32 and the portions 42 and 46 of the strip are formed by appropriate bending. Attention is now invited to Figures 4 and 5 where a modification of the invention is illustrated as being used with a brush head 52 having a handle 54 The body of the attachment 56 is shaped to conform to the upper surface contour of the brush head 52 It consists of a strip 58 of metal having an opening 60 in it through which the brush handle 54 is adapted to pass A collar 64 is welded or otherwise fixed to the strin 58 and has its bore in registry with the aperture 60. Handle 54 is adapted to be passed through the bore of the collar 64 and to be held in place by a fastening device somewhat similar to that shown in Figure 2 Preferably, a setscrew 66 passed through a threaded opening in the wall of collar 64 and having an eye 68 thereon is used. The strip 58 has a portion 70 on one side of the collar 64 which fits flat against a surface of the head 52 Portion 70 of the strip 58 has an angulated end portion 72 integral therewith and adapted to engage the corner 74 of the head 52 and underlie the same A similar angulated end portion 76 on the opposite side of the strip 58 is arranged to engage the corner 78 of the brush head 52 The brush corners 74 and 78 are shown as being of a small radius curvature, and therefore, the angulated portions 72 and 74 are shaped to conform thereto 70 Instead of welding collar 64 to strip 58, the attachment may be made of one piece by splitting a collar and cutting chordally at the inner ends of the slits Then the slit portions of the collar are shaped to be flat

in cross 75 section and curved longitudinally as shown in Figure 5. Figures 6 and 7 demonstrate a further modification of the embodiment of Figure 2. The attachment is made from a single piece 80 blank from which a tongue is struck so that the clamping legs 80 and 82 may be made therefrom, leaving an enlarged opening 84 in the strip 86 These legs have openings 87 and 88 therein through which the brush handle 89 is 85 adapted to pass when entering the threaded aperture 90 of the brush head 91 The screw 92 is identical in construction and function to the screw 34, and it passes through a connecting panel 93 that holds the legs 80 and 82 in proper 90 assembled relationship to each other. The strip has a portion 94 which extends from the leg 82 and bears against a surface of the brush head 91 Angulated end portion 95 of the strip is in engagement with the corner 96 95 of the brush head to serve a clamping function, as described in connection with the previous embodiments On the opposite side of the strip, there is an angulated end portion 97 which is normally in engagement with the 100 corner 98 of the brush head. Attention is now invited to Figures 8 and 9 wherein a further modification is illustrated. In this form of the attachment for the broom head 100, the handle 102 is held in place by 105 means of a clamp 104 which is very similar to the clamp 99 of Figure 7 However, note that the brush head 100 has square corners 106 and 108 and the handle 102 is tapered to fit in tapered aperture 110, the handle being wedged 110 thereinto This is a common type of broom used by many sanitation departments of cities for street cleaning One of the purposes of this illustration is to show that the handle locking attachment may be used with various types 115 of implements and that it need not be restricted to an implement which has its handle threaded into the head. The handle locking device is made of a strip 114 very similar to the strip 86 and clamp 104 120 is formed from a tongue that is struck from the strip 114 However, inasmuch as the head 100 is practically square in cross-section, the angulated portion 116 is at right angles to the flat portion 118 which extends from one leg of 125 the clamp 104 For the corner 108, the strip 114 is similarly shaped In use of the attachment of Figure 1, it is merely slipped over the end of the handle, and when brought to bear against the head 12, the screw 34 tightened 130 784,813 legs having registering apertures therein 50 through which the handle passes.

PATENT SPECIFICATION Inveator: SVEND HELGE KRISTIANSEN Date of Application and filing Complete Specification & No 34202 /55. Complete Specification Published Oct 16, 1957. Index at Acceptance: -Class 25, A( 18: 22). International Classification: -F 23 L COMPLETE SPECIFICATION Improvements in and relating Caps or We, NORDISK VENTILATOR Co AKTIESELsiu B, a body corporate organised and existing under the laws of Denmark, of Nestveb, Denmark, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the toliowing statement:-

This invention relates to ventiliators provided with caps or covers, especially but not exclusively ship's ventilators. In modern ships, ventilators with built-in fans are extensively employed, preferably in the form of axial blowers each comprising a motor directly coupled to an impeller, the motor generally being an electric one, but it may also be of another type, e g an air motor. Such motors require periodic inspection; for instance if the motors are electric motors the 2 C carbon brushes require to be renewed from time to time Consequently it must be possible to have access to the installed motors. In some instances the fan is arranged some way down the ventilator which is then provided with inspection doors affording access to the caron brushes, but practical reasons require that these doors be as small as possible, which involves that the person inspecting the motors has inconveniently little space in which to work. Moreover, if the whole fan or major parts thereof have to be removed it is necessary to dismount the ventilator completely, and as the ventilator often is of considerable dimensions, the dismounting entails much work. This work may be diminished if the ventilator is constructed with so large a door that the fan with the motor may be removed through the doorway However, in this case the doorway will involve a considerable weakening of the ventilator, so that it will be necessary to provide the ventilator with strengthening members and thereby to increase the initial cost. Another disadvantage of arranging the fan lPrice 3 s 6 d J to Ventilators provided with Covers some way down the ventilator is that the motor, which is generally large compared with the impeller, takes up too much cross-sectional space in the ventilator, and therefore the loss of pressure by the passage of the air past the motor is rather considerable For this reason and in order to obtain the smallest possible eddy loss (loss caused by turbulent flow) the terminal box of the motor is often mounted on the outside of the ventilator, where it is unpretected, and this requires a special outlet for the cable passing up through the ventilator. The above mentioned drawbacks in connection with the pressure losses and eddy losses may be remedied in the manner that the fan is arranged with the motor in the uppermost, preferably conically extended, part of the ventilator immediately under the cap or cover where the velocity of the air above the motor is small By this arrangement of the fan the terminal box even when fitted dierctly to the motor does not cause any essential reduction in the efficiency of the fan On the other hand, when the fan and the motor are arranged in this way, it is difficult to have such doors as will give even a fairly convenient

access to the motor, and it has hitherto been necessary, both at regular inspections and for dismounting and repairing the motor driven fan to remove the cap or cover in order to get access to the fan. The cap itself is very heavy, and consequently a crane or winch has been necessary in order to remove it; where only the carbon brushes of the motor require to be renewed this is an undesirably complicated operation. This last mentioned disadvantage might probably be remedied by hingedly connecting the cap to the ventilator and providing it with a suitable counterweight Experiments have proved, however, that such a construction is extremely unsuitable for practical purposes especially when the ventilator has to be used on a ship, fisrt and foremost because the weight of the cap, which in itself is very great, would be essentially increased in this manner, which 78498 14 Nov 29, 1955. 2 784,814 should be avoided-both in view of weight and in view of strength, secondly because the cap would become unsymmetrical, which at least on ships has to be avoided on account of the air resistances. The present invention relates to a ventilator provided with a cap or cover in the upper, preferably conically shaped, part of which ventilator there is a fan driven by a motor, preferably an electric motor, and the object of the invention is to enable a comparatively easy displacement of the cap or cover in such a manner that access to the motor is obtained from the top, and without it being necessary to provide the cap with counterweights or similar members that would considerably increase its weight. According to the invention this is obtained in that the cap or cover is pivotally connected to the ventilator partly by paeans of at least a main linkage pivoted at the upper end to the cap or cover and at the lower end to the ventilator, and partly by means of at least one guide member so arranged that when the cap or cover is tilted from its operative position in which it covers the ventilator opening to a position in which it uncovers said opening, the centre of gravity of the cap or cover follows a substantially flat horizontal curve In this manner, in spite of the heavy weight of the cap, only a comparatively small force is required to move it, the more so as the slight upward movements of the centre of gravity take place by means of a small force applied through a large leverage. The necessary guiding of the cap during its movements may e g be obtained by a guide wheel mounted on the cover and engaging a guideway rigidly connected to the ventilator. However, it has been found advantageous to guide the cap by means of a guide lever which is pivoted to the cap and to the ventilator and which, when the cap or cover is in its operative position covering the ventilator opening is located at a greater distance from the centre of

gravity of the cap than the main linkage. Provided, as normally is the case in practice, that the cap or cover only has to be tilted a little less than 900 the guide lever is sufficient to ensure the desired flat curve of movement of the centre of gravity of the cap or cover The construction involves that friction owing to slide resistance is avoided and consequently that the movements of the cap or cover are opposed by as little a friction as possible. The invention will be fully understood from the foregoing together with the following detailed description aided by the accompanying drawings, in which:Fig 1 represents a longitudinal section through one embodiment of the ventilator along the line I-I of Fig 3, the motor and fan being added but not shown in section; Fig 2 represents a longitudinal section through the upper part of the ventilator shown in Fig 1 along the line 1 I-11 of Fig 3, Fig 3 repersents a cross section through the ventilator and cap; and Fig 4 is a view similar to Fig 1 but of 70 another embodiment. In Figs 1 to 3, 1 indicates a ventilator the upper end of which is provided with a conical extended part 2 Within this extension there is an electric fan comprising an electric 75 motor 3 and an impeller 4 directly mounted on the shaft of this motor The fan is secured in the part 2 by means of supporting bars 5. The motor 3 is provided in conventional manner with a terminal box 6, and with a 80 commutator cover 7 that has to be removed when the carbon brushes are to be inspected or renewed. The ventilator is equipped with a top cap or cover 8 This cap or cover is connected to 85 the part 2 of the ventilator by means of a main linkage comprising two links 9 arranged symmetrical relative to the sectional plane I-I in Fig 3 and acting together as a single link. The upper end of each link 9 is pivotally con 90 nected to the cap or cover 8 by means of a pin and its lower end is pivotally connected to the part 2 by means of a pin 11. In the position of the cap 8 shown in lull lines in Fig 1 the links 9 are situated behind 95 the centre of gravity 12 of the cap, and at a farther distance behind its centre of gravity the cap is connected to the part 2 by means of a guide lever 13 pivotally connected at its upper end to the cap by means of a pin 14 and at its 100 lower end to the part 2 by means of a pin 15. The length of the lever 13 and the points of location of the pins 14 and 15 are such that during the swinging of the cap between its operative position shown in full lines in 105 Fig 1 and its open position shown in dotted lines, the centre of gravity 12 of the cap 8 is constrained to move along the curve 16 shown in dotted lines Simultaneously each pin 10 of the links 9 moves along a circular arc

17; the 110 pin 14 of lever 13 moves along a circular arc 18; the top left hand point of the cap in Fig. 1 moves along a curve 19; and the top right hand point of the cap moves along a curve 20. As appears from Fig 1 the curve 16 of the 115 centre of gravity is relatively flat so that during the swinging operation of the cap its centre of gravity is displaced up and down to only a very limited extent, and therefore a relatively small force applied to left hand portion of the 120 cap in Fig 1 is sufficient to swing the cap from one of its positions to the other. However, owing to the small force necessary for moving the cap, it may be necessary to provide means for preventing the cap from being 125 displaced unintentionally as by the wind for example To retain the cap in its operative position a bar 21 is provided which for instance may be welded to the cap 8 and which can be releasably fastened to the ventilator part 130 784,814 784,814 2 by means of a bolt 22 To retain the cap in its open position a latch 23 is pivotally secured to the ventilator so as to engage a strap 24 on the fully open cap. As appears from Fig 1 the plane that passes through the pins 10 and 11 of the links 9 when the cap 8 is in its operative position is inclined in the upward direction towards the vertical through the centre of gravity 12 of the cap with the result that during the first part of the opening movement of the cap follows a slight upwardly extending curve This involves that the cap has a natural position of rest in its operative position, so that the danger of an unintentional and consequently uncontrolled opening of the cap, e g in consequence of a gust of wind immediately after the bolt 22 has been removed, is practicallj avoided. For the same reason the guide lever 13 may also, as appears from the curve 16 in Fig 4, be mounted to act so that also the first part of the closing movement of the cap causes a slight upward movement of its centre of gravity 12 The embodiment shown in Fig 4 differs from that shown in Figs 1 to 3 only by a somewhat different relative arrangement and dimensioning of the links 9 and the guide lever 13; in this embodiment these members are arranged in such a manner that the curve 16 along which the centre of gravity of the cap 8 moves when the cap is swung has its trough in a position corresponding to a half-open position of the cap This has the advantage that once in said position the cap tends to remain there In this manner it is obtained that for short inspections of the fan or for renewing the carbon brushes for example, it is only necessary to swing the cap to this intermediate position in which it will then remain On account of the comparatively easy movability of the cap this automatic retention of the cap 8 in said intermediate position should in practice not be relied upon, but

suitable supporting means should be provided, e g in the form of a releasable securing bar, or the position may even be secured by the hand; otherwise there is the risk that a strong gust of wind will swing the cap back to its operative position. The embodiments shown may be modified in various details within the scope of the invention, as set forth in the appended claims, as will now be readily understood.

COMPLETE SPECIFICATION. Improvements relating to Shoes and Methods of Making Same. We, TODDLERS FOOTWEAR ( 11954) LIMITED, a British Company, of Toddler Shoe Works, 47 & 49 Tudor Road, Hackney, London, E 9, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:-

This invention relates to shoes and methods of making same, and has for its general object to provide shoes (which term is used broadly and is not intended herein to exclude boots or bootees) adapted to give strength and support at the heel without the use of normal heel stiffeners. More especially the invention may be said to concern shoes of the kind comprising an exterior part, generally of thicker material than is usually employed in an upper, extending up the back of the shoe as well as underneath it, this part forming either a long sole extending from the toe to substantially the top of the heel of the shoe, or an extended heel piece. A further object of the invention is to provide a strong and effective shoe of this kind which may be durable in wear and comfortable in wear The invention is especially applicable, although not confined to infants' or childrens' shoes. The invention provides an improved shoe comprising an upper of any usual pattern, but with quarters of such shape that when joined together they form an opening at the bottom permitting them to be there folded over smoothly at the rear on to a last, an insole adapted to extend from toe substantially to the top of the joined quarters at the back and adhesively affixed inside said quarters, and a similarly long outer sole attached by adhesive at the bottom to the insole and the edges of the upper, and at the lPrice 3 s 6 d l back of the shoe to roughed up surfaces of the quarters substantially to the top thereof. The quarters may be characterised by each having a part extending upwardly at the rear above the normal level, and the insole and sole both be adapted to extend and be affixed substantially as far as the top of the extension so formed A wedge may be interposed at the heel between sole and insole Moreover either or both insole and sole may initially be formed in two pieces adapted to be joined neatly by adhesive. In order that the invention may be clearly understood and readily carried into effect, the same will now be described with reference to the accompanying illustrative drawings, wherein:Fig 1 is a plan view of a long or extended insole adapted to extend from the toe substantially to the top of an extension formed at the top of the rear part of joined quarters; Fig 2 is a like view of a similar long sole; Fig 3 is a plan view of a heel wedge; Figs 4 and 5 show a long sole initially formed in two pieces, in other words as a sole and an extended heel piece, said two pieces being adapted to be joined neatly by adhesive; Fig 6 is a side view of the heel wedge; Fig 7 is a side view of the sole shown in Fig 4; Fig 8 is a side view of the heel piece shown in Fig 5; Fig 9 is an elevation of a short quarter,

characterised by an extension at the top, and a portion cut away at the bottom rear; Fig 10 is a perspective view of a pair of quarters joined together by a stitched seam; Fig 11 is a perspective view of an upper with a long insole in position after lasting on a last appropriately formed for carrying out the present invention; PA c 9 4,3 s, Y c e ? /:) Fig 12 is a similar view of the same after roughing up in preparation for securing a long sole by adhesive; Fig 13 is an enlarged cross section through the rear portion of last, insole and quarters substantially on the line XIII-XIII of Fig 12; Fig 14 is a side elevation of one form of sandal type shoe according to the invention, embodying a heel wedge and a long sole extending up the back; Fig 15 is a rear view of a similar shoe; and Fig 16 is a side elevation of a shoe embodying a long sole initially formed in two pieces, as a sole and heel piece. The method of making may be described first with reference to the simplest form which comprises a single insole 1 which may conveniently be shaped substantially as shown in Fig 1 affixed to the inside of an upper indicated generally by the number 2 and a single long outersole 3, Figs 2 and 14, affixed to the outside of the upper. The insole 1, preferably skived thin at the extended end 4, is initially shaped to conform to the bottom and back part of a last 5 which has a substantially flattened surface 6 (see Fig 13) more or less tapering up the back of the heel to the narrowest part at the top, and is then fitted into an upper 2 of any type e.g sandal, eyeletted, or bootee type, and having quarters 7, which may be long, short or even formed integrally with the forepart of the upper, each formed with an extension 8 at the top of the rear part, and so shaped at the bottom that when joined together at a central stitched seam 9 (Fig 10) at the rear they form a more or less V-shaped opening 10 with outwardly curved arms 11 so that they can be folded over smoothly onto the last 5 The insole 1 is then fixed inside the rear of the quarters 7 of the upper 2 by adhesive. The appropriately shaped last 5 above mentioned is then inserted into the upper 2 in correct position for lasting the upper to the insole The lasting may be effected in any usual or convenient manner such as by a tack lasting machine or by hand with tacks (tacks being shown in Figs 11 and 12), adhesive or by stitching thread on any appropriate maehine. When lasted as shown for example in Fig 11 the upper 2 is roughed up as shown in Fig 12 all round the lasted edge 12 at the bottom of the last and up the back of the last to the shape of a feather edge created by the shape of the back and heel of the above mentioned last Although this roughing up, compare Figs 11 and 12, may be expected to break the stitches 9 that initially united the two quarters 7 at the

back, the upper 2 does not there become loose or fall apart because it was previously affixed to the part 4 of the insole 1 extending up the back, and remains secure upon the last 5 for the next operation. The next operation consists in attaching the single long outer sole 3 to the upper 2, preferably with an interposed heel wedge 13 70 (Figs 3, 6 and 14) of appropriate shape and skived at each end For this purpose the sole 3 is preferably previously roughed up, and after adhesive has been applied is fitted into position with the top of the rear part 75 14 thereof substantially level with the extension 8 of the upper and 4 of the insole 1 previously mentioned, preferably after inserting a wedge 13 at the heel. To ensure security in wear the long sole 3 80 is preferably well hammered or pressed to the shoe on the last all over the bottom and up the rear part 14. The complete sole 3, and wedge 13 if present, can then be trimmed to conform 85 generally more closely to the shape of the bottom and back of the specially designed last 5 aforementioned, and the extension formed at the top of the rear part of the shoe, now consisting of part of the upper, insole 90 and sole is then trimmed off or into required shape, as shown for example in Figs 14 to 16, by a tool designed so to shape the top of these parts that the shoe will be comfortable in wear 95 The method above described is also applicable using an insole initially formed in two pieces andlor an outer sole initially formed in two pieces, instead of the single long insole 1, 4 and a single long outer sole 3, 100 14 above mentioned In each case the sole piece would extend to the rear under the heel as usual and be skived at its rear end, and an extended heel piece with a part to extend up the back of the heel would be skived at 105 its front end, so that the two pieces could afterwards be joined neatly by adhesive. Where such a shorter outer sole is used with an extended heel piece, a heel wedge 13 is usually unnecessary 110 Figs 4, 5, 7 and 8 illustrate an outer sole formed initially in two pieces 31 and 141 adapted by skiving to be joined neatly by adhesive and in the case of the sole part 31 the skiving would also roughen what might 115 normally be a smooth outer surface The skived portion of the sole part 31 is indicated at 311 and that of the extended heel piece part 14 ' at 1411; they preferably overlap about the amount indicated by those 120 Figures to ensure a neat and firm joint. Clearly an insole could be likewise formed in two pieces. Figs 14 and 16 also show that the heel wedge 13 or the sole piece 31 may extend a 12 l 5 little way up behind the heel. The edges of the sole, and wedge or extended heel piece as the case may be, can be trimmed to conform somewhat more closely to the shape of the bottom and back of the 130 784,815 784,815 last, and

consequently to the shape assumed by the adjacent parts of the upper than Fig 15 indicates. The insole and outer sole, whether in one or two pieces, may be made of any usual or appropriate material, such as leather, a leather substitute, or rubber In the case of rubber soles, these may initially be moulded to substantially the desired form, and be attached by adhesive solution or fitted by any known vulcanising process or other method. Obviously, if desired, other parts usual in shoe construction may be employed, such as socks, heel lifts or mid-soles, and linings or partial linings (which may be merely edge strengthening or foot grip strips) where appropriate in the quarters, without departure from the invention. It may be noted it is entirely novel that although stitches 9 uniting the quarters 7 at the rear are broken, by a roughing up operation, the shoe upper 2 remains intact upon the last owing to prior internal fixture of the quarters 7 thereof up the back to a long extended insole 1 or an internal heel piece with extension (not shown). It may be seen that the invention may also be said to consist in an improved shoe, that can be made by a method substantially as above described Such an improved shoe may comprise, for example, an upper 2 generally of any usual pattern, but with quarters 7 characterised by each having a part 8 extending upwardly at the rear above the normal level, and of such shape as, when joined together, to form an opening at the bottom permitting the quarters 7 to be there folded over smoothly onto a last 5 appropriately shaped at the rear, an insole 1 adapted to extend from toe substantially to the top of the upward extension 8 at the back of joined quarters 7 and adhesively affixed to the inside of said quarters, and a similarly long outer sole 3 attached by adhesive to the insole 1 and edges 12 of the upper 2 at the bottom of the shoe, and at the back of the shoe to roughened up surfaces of the quarters 7 substantially to the top of the upward rear extension 8 thereof. Obviously an improved shoe in accordance with the invention may be formed with what was initially a two piece insole and /or a two piece outer sole, each comprising a sole piece as 31 and an extended heel piece as 141, afterwards joined together Also other parts may be included as hereinbefore indicated. " Adhesive," " adhesively and similar terms are used herein to cover any means adapted to stick parts together, as distinguished from stitches, such as rubber solutions, vulcanisation (in the case of rubber), and shoe cements or the like.

PATENT SPECIFICATION 784,816 Date of Application and filing Complete Specification: Dec5, 1955 No 34794/55. Application made in Germany on Dec 4, 1954. Complete Specification Published: Oct 16, 1957. Index at Acceptance:-Class 79 ( 4), B 3 F. International Classification:-B 62 d. COMPLETE SPECIFICATION Improvements relating to Resilient Mountings for auxiliary frames or

transverse members carrying road wheel suspensions on vehicles We, DAIMLER-BENZ Ax TIENGESELLSCHAFT, of Stuttgart-Untertiirkheim, Germany, a Company organised under the laws of Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- For the purpose of improving the running properties and facilitating the installation and removal of an axle unit, it is known to provide an auxiliary frame or transverse member which carries road wheel suspensions and possibly also the engine and gearing and which is in turn connected to the vehicle superstructure (for example a frame or self-supporting vehicle body) through the medium of resilient elements, particularly rubber cushions Shocks and vibrations originating from the road or from the engine can thus effectively be kept away from the vehicle body, this being important, particularly when use is made of steel bodies, which tend to boom. The invention has as its particular object the further development of such resilient mountings for the said auxiliary frames or transverse members. According to the present invention, in a vehicle with a resilient mounting, for an auxiliary frame or transverse member carrying suspensions for a pair of road wheels, comprising flat resilient cushions, generally of rubber disposed between said auxiliary frame or transverse member and the superstructure of the velicle, the cushions are disposed so that they are located, in plan view, at the corners of a rectangle and appear, in end elevation, as pairs with one member of each pair on each side of the central vertical longitudinal plane and, in side elevation as pairs with one member of each pair forwardly and the other rearwardly of a transverse vertical plane of the said auxiliary frame or transverse member, the members of a pair, whether a pair viewed in end elevation or a pair viewed in lPrice 3 PM 41 " side elevation, presenting oppositely inclined supporting surfaces. Vehicles are known in which rubber cushions interposed between a transverse member carrying wheel suspensions and the vehicle 50 superstructure are inclined at an angle in a transverse cross-section only, but not in a longitudinal section as well The object of the inclined position is to obtain a determinate centre of rotation, for transverse swinging of 55 the vehicle superstructure, which is located above the road. Separate rubber cushions are provided for the abutment of the transverse member against the superstructure in the longitudinal and 60 transverse directions, so that a relatively large number of such cushions is necessary. In contradistinction thereto, the arrangement of the resilient

cushions according to the present invention has the advantage that not only 65 forces directed vertically but also forces directed horizontally, in both the longitudinal and the transverse directions of the vehicle, can be transmitted by compressive stress in the cushions 70 At the same time, due to the arrangement of the cushions in pairs, only four such cushions are required in all to take not only the vertical but also all the horizontal forces between the auxiliary frame or transverse member and the 75 superstructure. In one preferred form of construction, the pairs of cushions as seen in side view are arranged in a V-form which is the inverse of the V-form of the pairs as seen in end view 80 Preferably an inverted V-form is seen in a side view and an upright V-form in an end view of the vehicle. Such oppositely arranged V-formations of the cushions give a particularly stable resilient 85 connection between the auxiliary frame or transverse member and the vehicle superstructure The arrangement of the pairs in the form of an upright V as seen in end view gives, advantageously, a high instantaneous 90 centre for tilting of the superstructure in relation to the auxiliary frame or transverse member supported on the axle On the other hand, the arrangement of the pairs in the form of an inverted V as seen in side view has the effect that longitudinal forces acting from the axle or from the auxiliary frame or transverse member upon the superstructure produce components of force directed oppositely to the transverse forces on the superstructure, so that the tendency of the superstructure to tilt in relation to the axle is effectively counteracted. Braking moments and driving moments are dependably taken up by the rubber cushions. Further details and features of the invention will be clear from the following description of one embodiment illustrated by way of example in the accompanying drawings, wherein:Figure 1 is a diagrammatic side elevation of a vehicle, such as an omnibus, with a transverse member carrying the front axle and resiliently mounted in accordance with the invention. Figure 2 is a plan view of the arrangement shown in Figure 1. Figure 3 is a part of Figure I drawn to a much larger scale. Figure 4 is a section on the line 4-4 in Figure 2 but is also drawn to a much larger scale. Figure 5 is a diagrammatic front view of an arrangement such as is seen in Figures 1 and 2. In the drawings, a main frame 10 supports a superstructure 11, which may be made separately from the frame and be detachably connected to it, or which may be united with it to form a structural unit The main frame comprises longitudinal members 12 and 13, which are upwardly

bent in the forrtn of an inverted V in the region of the front axle as shown in Figure 1 Brackets 14, 15, 16 and 17 are attached to one side of respective longitudinal members 12 and 13 in the region of the inclined bent portions of said longitudinal members and have a corresponding inclination. Rubber cushions 18, 19, 20, 21 located at the corners of a rectangle in plan view (Figure 2) serve for the flexible connection of an auxilary frame or transverse member 22 to the frame 10. Front road wheels 23 are mounted on a rigid axle 23 d (Figure 5), which is sprung against the auxiliary frame 22 by means of coil springs 23 a or the like and which is abutted by thrust members 23 b (Figure 2), for example with the interposition of rubber (not shown), against the frame 10 Also, the axle 23 d may be connected with the auxiliary frame 22 by a radius arm or link 23 c, in the manner shown in Figure Alternatively, the front road wheels may be suspended (in a manner not illustrated) from the auxiliary frame 22 by means of link members or the like which are adapted in known manner for giving independent guidance of such wheels The rubber cushions 18 to 21 are in each case flat or in the form of a plate and are reinforced with metal plates 24 and 25, Figures 3 and 4, which are advantageously nondetachably joined to the rubber by vulcanisation The rubber cushions are detachably connected by the upper plate 24 directly to the longitudinal members 12, 13 and also, for 70 example by means of projections 14 a or the like, to the brackets 14 to 17 and by the lower plate 25, for example by means of projections 26 a or the like, to the brackets 26, 27, 28, 29. The latter are welded to the auxiliary frame 22 75 and are inclined, at their surfaces serving to receive the rubber cushions, to correspond to the brackets 14 to 17 or to correspond to the longitudinal members 12, 13 Moreover, as shown in Figure 4 in particular, the rubber 80 cushions 18 to 21 are made in the form of an angle as seen in a cross-section of the vehicle, one part (for example the past 18 a) being disposed in a horizontal position directly between the longitudinal member (for example 12) and 85 the respective bracket (for example 26) of the auxiliary frame 22, while the other part (for example 18 b) is directed upwardly and outwardly at an obtuse angle and is supported by means of the projections (for example 14 a, 26 a) 90 against the respective bearing brackets ( 14 and 26 respectively) on the frame 10 and auxiliary frame 22 The projections ( 14 a and 26 a) may be rigidly connected to the reinforcing plates ( 24, 26) or to the brackets ( 14, 26 and so on) and 95 detachably connected (for example by means of screws) to the other parts. In all cases, the arrangement is such that the rubber cushions 18, 19 and 20, 21 respectively are so disposed in pairs both on either side

of 100 the transverse member 22 and on either side of the vertical longitudinal central plane of the vehicle that, seen in a side view or in a longitudinal section of the vehicle, they are located in the form of an inverted V, while 105 when seen in end view or cross-section of the vehicle they are located in the form of an upright V and hence, in the former case, determine a low axis of rotation (approximately level with the road) and in the latter case a high axis of 110 rotation (approximately level with the centre of gravity of the vehicle) of the auxiliary frame 22 in relation to the superstructure of the vehicle Both in the longitudinal direction and in the transverse direction of the vehicle, 115 dependable abutment is obtained between the auxiliary frame and the superstructure and hence, in spite of effective damping of shocks and vibrations originating from the road wheels, good stability of the auxiliary frame with 120 respect to the superstructure is obtained, since turning moments (for example driving and braking moments) acting about a transverse or longitudinal axis are both dependably taken up. The engine 30, indicated in Figure 5, may 125 also be resiliently supported on the auxiliary frame or transverse member 22, for example at 31 It may be mounted either completely on the auxiliary frame or transverse member or supported, preferably also resiliently, only partly 130 784,816 presenting oppositely inclined supporting 30 surfaces. 2 A vehicle as claimed in claim 1, wherein -the V-form of the supporting surfaces as seen in end view is the inverse of the V-form of the supporting surfaces as seen in side view 35 3 A vehicle as claimed in claim 2, wherein the V-form of the supporting surfaces as seen in side view is that of an inverted V and the V-form of the supporting surfaces as seen in end view is that of an upright V 40 4 A vehicle as claimed in any one of the preceding claims, comprising flat cushions of bent or angular formation, whereby one part of a cushion is horizontal so as to be adapted for taking perpendicularly acting forces whilst 45 the remainder of such cushion is inclined at an obtuse angle to the horizontal so as to constitute part of a V-formation. A vehicle comprising a resilient mounting for an auxiliary frame or transverse member 50 carrying suspensions for a pair of road wheels of a vehicle, substantially as hereinbefore described with reference to the accompanying drawings. JENSEN & SON, 77, Chancery Lane, London, W C 2. Chartered Patent Agents. thereon, the remainder being supported, preferably also resiliently, directly on the vehicle superstructure The main support on the auxiliary frame or transverse member may be effected in a transverse

plane passing through the centre of gravity of the power unit comprising the engine 30, so that, for the rest, only a simple support, taking only slight forces, on the auxiliary frame or vehicle superstructure is required Consequently, very soft rubber cushions can be used for this purpose.

Description of GB784817 (A)

PATENT SPECIFICATION Date of Application and filing Complete 84,817 Specification: Dec7, 1955 No 35159/55. _____ Application made in Germany on Dec 7, 1954. Complete Specification Published: Oct 16, 1957. Index at Acceptance:-Class 34 ( 2), G( 1 C 2 A: 4 821 B). International Classification:-F 26 b. COMPLETE SPECIFICATION Process and apparatus for simultaneously Drying and Cooling White Sugar coming from a Centrifuge We, BUTTTNER-WE Ric E AIC Ti ENGESELLSCHAFT, a German corporate body, of K Crefeld-Uerdingen, Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The present invention relates to a process and apparatus for drying

and simultaneously cooling the white sugar coming from a centrifuging station. A drier which has proved to be particularly advantageous for carrying out this treatment process is an annular disc drier of the type in which the upper part is designed as a drying zone and the lower part as a cooling zone This apparatus consists essentially of superimposed annular discs for accommodating the material to be treated, discs being so arranged that after after each revolution of the annular disc system, the sugar is transferred to the next subjacent annular disc The consequence is, therefore, that during the entire drying and cooling process, there are only as few rearrangements of the layers of sugar as there are annular discs provided, so that a gentle treatment of the sugar is guaranteed and the sharply defined edges, the glitter and the crystal structure of the sugar is thereby maintained It should also be mentioned that fans are arranged in the free internal space enclosed on the annular discs, which fans serve for constantly circulating the drying and cooling air. It is also already known for a rotating compensating hopper to be connected ahead of an annular disc drier of the type which has been described above According to a further proposal, the said compensating hopper is simultaneously used for the initial drying of the sugar by conducting through it all the exhaust air of the said drier Such an initial drying has proved to be advantageous, particularly when treating finely crystalline sugar, this being the type of sugar with which the lPrice 3 s 6 d l industry is now mainly concerned The very fine sugar crystals, which still contain all the moisture, tend to cake together in the annular disc drier on the uppermost stages, owing to the small amount of change in the layers, so 50 that conglomerates are formed On the other hand, it has been confirmed by exhaustive experiments that such a caking does not take place if the initial drying is carried out down to a specified water content while the layers of 55 material are constantly moved, for example in a rotating drum or like device It could be established that the frequent changing of the layers of the sugar masses while still moist does not exert any unfavourable influence on the 60 maintenance of the structure, the sharp-edged formation, and so on, provided that the heat content does not fall below 0 2 %. In order to complete the known working method, it is proposed according to the present 65 invention that only a component quantity of the exhaust air from the annular disc drier should be conducted through a preliminary drier of the type referred to above and that this air should return into the disc drier after 70 flowing through the preliminary drier, so that an air circulation is set up. By varying the output of a circulating fan fitted in the return

conduit of the preliminary drier, fitting at least one throttle valve in the 75 return pipe of the fan and so on, it is possible for the amount of air circulated through the preliminary drier to be adapted to the given conditions An essential advantage of the method referred to is that a dust extractor at 80 the preliminary drier can be dispensed with, such an extractor being indispensable if the air from the said preliminary drier is conducted directly into atmosphere The constant circulation of the sugar masses in the preliminary 85 drier and the velocity at which the warm air travels through the said drier are the cause of ultra-fine sugar crystals being entrained by the air When operating in accordance with the present invention, these crystals pass with the 90 Pries 25 p returned air stream into the annular disc drier in which they are deposited This action depends on the fact that separate air-circulation zones are set up inside the annular disc drier, corresponding to the number of the centrally arranged fans provided in the drier The air flows from the fans radially over the annular discs and is then sucked in again radially by the fans after a sharp change in direction, a component quantity of air passing in each case into the zone disposed just above These circulating currents also take-up the air returned from the preliminary drier It is thus shown that the ultra-fine sugar crystals introduced into the circulating currents are separated out at the places where the air changes direction, more especially immediately behind the outer edges of the annular discs, and sink down in the annular passage between the housing of the drier and the arrangement of annular discs. Moreover, fine sugar crystals contained in the circulating air currents are also deposited on the layers of sugar. The particular type of annular disc drier as referred to above thus makes it possible for the air returned from the preliminary drier into the annular disc drier to be freed from the entrained sugar crystals as it travels to the exhuast air chimney or stack. The invention is also concerned with an apparatus for carrying the process into effect. One constructional embodiment of the invention is shown, by way of example, in the accompanying drawing, wherein: Figure 1 is a diagrammatic view of an annular disc drier with a preliminary drier; and Figure 2 is a section through the annular disc drier on the line A-B in Figure 1. Referring to the drawing:The housing 1 or the annular disc drier is fitted with a number of annular discs 2 which are arranged one above the other and are fixed to a rotary frame 3 Slots 3 a are left at the circumference of the annular discs and the sugar masses are transferred through the slots by means of stripper devices 4 on to the

next subjacent annular disc It will be obvious that such stripper devices are provided on each stage of the drier, so that the sugar supplied at 5 gradually descends and leaves the apparatus at a discharge position 6 Through a pipe connection 7, cooling air is introduced into the apparatus and this air is first of all circulated in the lower part of the apparatus by means of a fan 8, whereby the sugar is given the required final temperature The slowly ascending air is then warmed by heater elements 9 and in the uppermost part of the apparatus serves to dry the sugar Some of the waste air escapes through an exhaust air pipe 10, while the remainder flows into a preliminary drier 11, which in this case is constructed as a rotating drum drier The sugar masses introduced at 12 are initially dried in the drum drier with constant rearrangement of the layers, the preliminary drying being carried out to such a degree that it is not possible for the sugar to cake in the annular disc drier The warm air drawn through the drum drier returns by way of a pipe 13 and a fan 14 into the annular disc 70 drier Due to the particular nature of the ventilating system, the fine sugar crystals contained in the air which is returned are deposited in the annular disc drier as already described The amount of the current of warm 75 air which is returned from the drum drier can be regulated by varying the power of the fan 14 or by adjustment of a throttle valve 15 in the fan discharge. It should also be mentioned that it is ex 80 pedient for an annular plate 16 to be arranged between the drying and cooling zones of the annular disc drier, so that the transfer of the air from the cooling zone into the drying zone can definitely only take place by way of the 85 slots 3 a in the annular discs 2. The process which has been described and also the equipment for carrying it into effect can be modified and constructed in various ways within the scope of the invention It is 90 essential that for the preliminary drying of the sugar an apparatus shall be employed which will guarantee a constant changing of the layers of the sugar masses Instead of the annular discs 2 formed with slots 3 a the discs can also 95 consist of hinged sectors which discharge the sugar on to the next subjacent stage when they are hinged downwardly Furthermore, it is possible for the warm air flowing from the annular disc drier into the preliminary drier to 100 be heated, for example, by an air heater or by admixing hot gases.
