Patented June 6, 1933 UNITED STATES PATENT OFFICE FAY D. KINNE-Y, OF SOU'I'HBRIDGE, MASSACHUSETTS, ASSIGNOR TO UNITED S HOE MACHINERY CORPORATION, OF IPATER-SON, I TEW JERSEY, A. CORPORATION OF NEW JERSEY BOXING CEMENTING MACHINE Application filed October 16, 1929. Serial No. 400,130.

Letters Patent No. 1,830,114, granted-Nov. 3,

1931, upon my application, in the use of which machine cement is projected upon the exposed foxing area of a shoe which is protected above that area by a surrounding 0 shield. An important object of this invention is to provide an improved machine of this general type.

In the manufacture of rubber soled tennis shoes, for example, it is the general practice to secure the margin of the sole to the upper of a shoe by means of an interposed strip of gum rubber called a foxing or a foXing strip which itself is secured to the canvas upper by a stripe of cement applied to the lower marginal portions of the sides of the upper. It is well understood in the art that the application of this stripe of cement, to prove commercially satisfactory, must be eflected quickly and cheaply and in a thick coating. Furthermore, the upper margin of the stripe of cement should be accurately located at a substantially uniform distance from the bottom of the shoe in order to secure the whole width of the foxing strip without extending above it.

In machines of the type under consideration, the extent of the foxing area to be coated is determined by a cooperating shielding device having an aperture through which V a portion of the shoe is moved to expose the foxing area to the action of cement applying means while the remainder of the shoe is protected by said apertured shielding device. Proper protection of a shoe demands relatively close cooperation between the shielding device and the shoe. Moreover, the run of work in any shoe factory includes shoes of radically different sizes and styles. In view of these considerations, the machine herein illustrated, in accordance with a feature of the invention, is provided with a shielding device which is made up of a plurality of movable sections overlapping at their ends, each section being flexible or distortable and thereby adaptable to-shoes of different sizes and styles. As illustrated, the various sections of the shield are mounted on slides so that they may be moved away from the shoe to open up the shield or moved into cooperative relation with the shoe as the shield is closed, The end sections of the illustrated shield are constructed and arranged to be wrapped around the toe and heel portions of the shoe.

In accordance with other features of the invention, the illustrated machine comprises a shoe ejector movable to carry a shoe out of range of the cement applying means and baflles are provided which may be interposed between the cement applying means and the shoe during the time interval when one shoe is being removed and another put in its place. As illustrated, automatic mechanism is provided for opening and closing the shield, raising and lowering the baffles and ejecting the coated shoe from the machine, all in proper timed relation.

As in the machine illustrated in United States Letters Patent No. 1,830,11l referred to, the illustrated machine is provided with a receptacle positioned beneath a shoe sup port and cement is projected in a spray upon the unprotected foxing area of the shoe by ro proved rotary projecting devices which operate by centrifugal force both to lift the cement from the receptacle and to project it upon an article to be coated. In the illustrated embodiment of the invention, these projecting devices are supported on the lower ends of vertical shafts and each comprises a cement feeding member in the form of a hollow member open at the bottom and dipping in the liquid in the receptacle, the hollow member being provided with a peripheral outlet adjacent to its upper end. This hollow member is herein illustrated as frustoconical and thus having a continually increasing diameter so that, under the action of centrifugal force, the liquid is impelled to travel up the inner surface and is projected out of the peripheral outlet between the hollow member and a disk by which it is supported on its shaft. The tendency of such a rotary .tion through the side plates and their supportmember to push the body of the cement away from its lower end, because of the friction between its outer surface and the cement, is overcome in the illustrated construction by providing a stationary baffle herein shown as a frusto-conical member surrounding and positioned close to the outer surface of the rotary cement applying member to resist the circulation of the liquid in the receptacle.

Provision is made, in the illustrated construction, for supporting a shoe in predetermined relation to the lower edge of the shielding device which as shown is brought into contact with the shoe at the upper edge of the foxing area. This shoe support is mounted for independent up-and-down adjustment of its ends. By means of this arrangement, it is possible adjustably to determine the width of the foxing area to be coated.

These and other features of the invention are more fully set forth in the accompanying description taken in connection with the drawings, in which Fig. 1 is an end elevation of the machine with parts broken away and in section;

A piece of work, such as a lasted tennis shoe 10, is presented to the machine by being lowered through an opening in a top cover 12 (Fig. 5) of a frame 14 and rested upon a work support 16 (Fig. 2). In this position the upper part of the shoe which is not to be coated is surrounded by a shielding device comprising a pair of side pieces 18 (Fig. 5) and a pair of end pieces 20 and cement picked up from a receptacle 22' (Fig. 1) is applied to the exposed foxing area of the shoe by means of four symmetrically positioned rotary spraying devices 24 (Figs. 1 and 5) which are effective simultaneously to coat the whole of the foxing area. After a sufficient quantity of cement has been applied, the machine operates automatically to raise a pair of baflle plates 26 (Fig. 1) which are interposed between the spraying devices and the shoe and to open the shielding devices; the machine then operates, by means of an ejecting grid 28 (Fig. 2) which is raised mechanically, to lift the shoe out of the machine to a position where it may be removed manually or received by a transferring mechanism of the kind illustrated in United States Letters PatentNo. 1,850,151, granted March 22, 1932, upon my application. After this the ejecting grid is carried back to its original position and the machine stops, it being understood, however, that the spraying devices are rotated continually during the period of use of the machine.

The frame 14 is a box-like structure having a large opening 30 (Fig. 2) at one side which is closed by a pair of doors 32 (Fig. 1). lVithin this frame is anelectric driving motor 34 carrying a pulley 36 which is belted to a pulley 38 on a counter shaft 40. From this counter shaft the various spraying devices 24 are driven by means of round belts 42. The motor shaft is connected through an Oldham coupling 44 to a short shaft 46 carrying a worm 48. This worm, mounted within a suitable grease-containing casing 50, meshes with a worm gear 52. The worm gear is mounted on a short shaft 54 (Fig. 2) which carries a small pinion 56 meshing with a larger gear 58 forming half of a clutch and mounted for free rotation upon a cam shaft 60. The other half of the clutch which is of a construction essentially like that shown in United States Letters Patent No. 1,843,232, granted February 2, 1932, upon the application of B. Jorgensen, comprises a circular member 62, of about the same size as the gear 58, which is keyed to the cam shaft 60 and carries a connecting device in the form of a pin 64 (Fig. 1) the inner end of which has a flattened face for engagement with ratchet teeth 66 formed upon a ring within the gear 58. When the pin is in one position it connects the clutch parts and when the pin is in another position it rides freely past said teeth. The connecting pin 64 is provided with a short arm 68 to which there is secured a spring 70 urging said pin in such a direction that the clutch will be closed and the two parts 58 and 62 will rotate together. The pin 64 is also provided with a'projecting stud 72 which extends through a slot in the peripheral face of the clutch member 62 and is positioned for engagement by the upper end of a clutch disconnecting lever 74. This lever is journaled in the frame of the machine and urged in counterclockwise direction by a spring 76 to bring the upper end into position to disconnect the clutch. The lower end of the disconnecting lever 74 is provided with a contacting piece 78 for engagement with a latch 80 on a trip lever 82 pivoted at the bottom of the machine and connected through a rod 84 with a starting treadle 86, said latch being urged to the position shown in Fig. 1 by a suitable spring 88.

The spraying members 24 which are on the near side of the machine as viewed in Fig. 1 are driven directly by a counter shaft 4:0, while those on the far side of the machine are driven by another shaft 41 (Fig. 2) con nected by a crossed belt 4L3. The cement receptacle 22 (Fig. 1) is partially filled ith cement during tne use of the machine and this cement is picked up by the driven spraying devices and projected upon a shoe, any surplus draining back into the receptacle. At the close of the days work, the cement may be removed from the receptacle through a suitable drain 90 extending out beyond the frame to a point where the cement can easily be caught in a bucket and said drain passage is closed at its outer end by a flap 92.

The various spraying or projecting devices 24 are identical and each one comprises a flat disk 9% (Fig. 1) mounted at the lower end of a driven shaft 96 extending up and down through hearings in a supporting arm 98 which is hinged on a lateral rod 100 so that the spraying device with its supporting arm 98 may be tilted back for cleaning. The driving belt of each spraying device extends up over idlers 102 mounted on said lateral rod 100 and around a pulley 104; on the shaft' 96 whereby the driving connection is not disturbed when the spraying device is tilted back. A hinged cover 106 and an adjacent removable cover 108 (Fig. bolted to the top of the frame of the machine, are provided completely to surround the driving mechanism just described. The directions of rotation of the various spraying devices are indicated by arrows in Fig. 3 from which it will be seen that sprays are projected from the four corners of a rectangle toward the shoe.

Each of the spraying devices picks up cement from the receptacle by means of an inverted frusto-conical hollow feeding member 110. This hollow feeding member 110 has an increasing. diameter and extends upwardly toward the flat disk 94 and is flanged at its upper end for attachment to the disk 94 near its periphery, said feeding member and said disk being separated by a narrow peripheral slot through which the cement is projected by centrifugal force and applied to the work. The picking up of the cement from the receptacle by the hollow feeding member 110 results from the action of centrifugal force upon the cement resting against the inner surface of said feeding member and urged upwardly along the inner sides thereof by reason of its constantly increasing diameter until the cement is thrown out of the peripheral slot.

It has been found that the friction between the outer surface of the feeding memher 110 and;the surrounding cement sets up a swirling action in the body of the cement which tends to cup out the cement and to hold it away from the lower open end of the hollow member. This action unhindered might be suflicient to prevent the cement from being picked up. The cupping action is effectively prevented, however, in the illustrated construction by baffles 112 associated with each of the spraying devices and illustrated as frustoconical hollow members substantially parallel to the feeding members 110, said baffles being supported by lugs 11% from the bottom of the receptacle 22. These baffles prevent the swirling or cupping action just described and cause the cement to remain in contact with the lower end of the hollow members 110 so that it is fed up through said members continuously.

The shoe as it rests upon the shoe support 16 must have a predetermined relation to the shields 18 and 20. i iccordingly, the shoe rest 16, having a raised rib portion 120, is detachably supported at its ends by hangers 122 (Fig. 11), these hangers being in turn supported by levers 12s which are fulcrumed in the frame. Means is then provided for adjusting the position of the levers 12 1 to vary the position of the work support 16 comprising hand screws 126 and 128 acting in opposition to springs 130 surrounding the bolts on which the hand screws are threaded. A wedge shaped lever 132 (Figs. 5 and 11) is provided at the toe end of the shoe support to permit fine adjustments of this end of the shoe with respect to the shields to care for variations in toe-spring in shoes of slightly different styles. The shields 18 and are slidably supported in the top cover 12 which has lateral lugs 134 (Fig. 10) for engagement with tapered studs 136 in the frame of the machine so that said cover may be lifted off the machine for cleaning purposes and readily replaced in position. The side shields 18, although of somewhat different shape, are substantially of identical construction and comprise thin plates, of brass, for example, each of which is secured to a casting 138 as by screws not shown. This casting has depending lugs 140 (Figs. 8 and 10) carrying a longitudinal rod on which are mounted distorting fingers 142, associated with each of which is a thumb screw 144 bearing against the under side of the casting 138 so that by adjusting said screws the shape of the shoe engaging edge of the shield 18 may be varied and more exactly determined to make it suit the particular style of shoe to be treated. Each of the castings is slotted at 146 (Fig. 9) for engagement with a stud arrying a thumb nut 148 so that the casting may be removably secured upon a slide 150.

Each of the slides 150 has a central rib 152 (Figs. 2 and 3) on its under face which is received in aslot 154 (Fig. 9) in the cover 12 and the slide is held in said slot by a plate 156 (Fig. 3) engaging the under side of the cover 12 and held in position on the slide by screws, of which one screw 158 (Fig. 9) has an upstanding head for engagement with an operating lever 160 which is fulcrumed on a stud 162 (Fig. 7) in the top cover and which is operated in a manner to be later described to move the slide in and out substantially radially of the shoe to bring the side shields 18 into cooperative relation with and preferably into contact with the shoe.

At the ends of the shoe are similarly shaped end shields 20 each of which is constructed of thin sheet metal and is properly shaped at its lower edge so that when brought into ongagement with the shoe, it will fit around the end of the slice exactly at the top of the foxing area to protect the upper of the shoe above that area. This end shield 20, instead of being shaped for exact engagement for any particular shoe, is supported at its center upon av slide 164 (Fi 11) and at its ends by swinging paddle-snaped levers 166 (Fig. 6), the arrangement being such that when the slide is moved forward the end shield will be caused to wrap itself around the curved end of the shoe either at the too or the heel, as the case may be. Each end shield is centrally secured to casting 168 (Fig. 11) which is slotted so that it may he slipped into engagement with a depending stud 170 on the slide, and held there by a spring-pressed pin 172. In order to cause the end. shields to wrap themselves around the ends of the shoe, the machine is organized so that the central portion of the shield may be brought resiliently into contact with the shoe and additional movement then imparted to the end portions so that it will wrap itself around the shoe. accordingly, the slide 164 which supports the central portion of the shield is itself slidably mounted in another slide 174 which extends across the top cover 12 (Fig. 8) and is supported atits ends by underhanging strips 17 6 on said cover. These slides are also movable substantially radially toward and away from the shoe to move the shields into cooperative relation therewith. Additional support for the slide on the cover is secured by means of a centrally disposed casting 178 which is bolted to said slide and which travels in a slot180 in the top cover and overhangs said top cover. Each end of the shield 20 is attached to a block 182. The outer end of each block 182 is reduced in thickness to fit the space between the under face of the cover 12 and the paddle-shaped lever 166, and has a rib 183 (Fig. 4) sliding in an open ended slot in one of the levers 166 as indicated by dotted lines in Fig. 7. This construction allows the ready removal of an end shield for cleaning or the substitution for one of different shape merely by raising the spring pressed locking pin 172, after which said end shield 20 may be moved endwise of the machine and disengaged from its central and end supports. Each of the paddle-shaped levers 166, by means of which these end supporting blocks 182 are carried, is pivoted at 188 upon a resiliently supported bolt 190 (Figs. 6 and 8) which slides within a tube 192 containing a spring 194. A stop nut 196 limits the inward movement of each of these bolts 190. Beside this pivotal support for the paddle-shaped levers 166, it will be seen that the slide 17 4 is provided with ledges 198 underlying the levers and that the levers pass through slots 200 in the slide 174 formed by grooves therein and cover plates 202 screwed down to the slide. The port-ions of the levers 166 which extend into these slots are formed into narrow tails 204 interconnected at each end of the machine by springs 206, these springs tending to swing each of the levers 166 in a direction to open the outer ends of the shield 20. The slides 164 and 174 are further interconnected for the purpose of operating the end shields by means of a bolt 210 (Fig. 11) which is secured to an upstanding portion of the slide 164 and which slips freely through an opening 212 (Fig. 8) in an upstanding portion 214 of the casting 178 on the slide 174. A spring 216 (Fig. 11) surrounding this bolt 210 tends to throw the slide 164 forward to the limit permitted by lock nuts 218 on the bolt 210, but permits additional movement of the slide 174 to wrap the ends of a shield around the shoe after the central portion thereof has contacted with the shoe. It will be understood that this wrappin action is facilitated both by the pivotal mounting of the supporting levers 166 and by the fact that each of these levers is mounted on a resiliently supported bolt 190.

In order to provide for the conjoint operation of the various shields 18 and 20 to bring them inwardly into cooperative relation with the shoe or to move them outwardly to permit the removal of the shoe, 9. connection is provided between each of the operating levers 160 associated with the side shields 18 and the slides 174 associated with the end shields 20. This connection is in the form of a bolt 220 (Fig. 7) slidably mounted in a swivel block 222 carried at the end of a lever 160 and pivotally secured at 224 to an ear 226 (Figs. 1 and 8) upon the casting 178, 214 which is bolted to said slide 174. A spring 228 (Fig. 7) surrounding said bolt 220 provides a resilient connection between an end slide and a lateral slide so that there is freedom of movement and no danger of injury to the shoe. Power for moving the slides is delivered to the end slides through an upright pivot stud 230 (Fig. 11) on which is detachably mounted a bolt 232. This bolt is removably secured to the stud 230 by means of a swinging cap piece 234 (Fig. 5)

held in position by a wing nut 236. Each of the bolts 232 has a clamp nut 238 at its outer end and is surrounded by a spring 240 (Fig. 2) through which movement is imparted to the bolt 232 and hence to the slides by one of a pair of similar levers 242 (Fig. 5). These levers, the ends of which carry swivel blocks slidably mounted on the bolts, are secured to the upper ends of upright shafts 244 journaled in the frame of the machine and provided at their lower ends with mitre gear connections 246 (Fig. 1) to a longitudinal shaft 248. It is not intended that this shaft 248 will have a full rotation but only that it shall be swung by means of a lever 250 having at its outer end a camroll 252 for engagement with a disk cam 254 (Figs. 1 and 2) mounted on the cam shaft 60. A single rotation of the cam shaft is effective, therefore, to move the slides to close the shields into engagement with the shoe and then at a later time to open up the shields to the position shown in Fig. 7.

The baffle plates 26 which may be raised into the range of the spraying devices to prevent the spattering of cement when the shoe is being presented or taken out are long rectangular plates which are interconnected at their ends by cross rods 260. Carrying-hangers 262 (Fig. 2) are secured to the cross rods and to the hangers there are rigidly secured operating arms 264 (Fig. 5) which are clamped on the reduced upper ends of upright rods 266 (Fig. 2). These rods are slidably mounted in suitable bearings provided in the frame of the machine and in protective casings 268 bolted to the ends of said frame. Each of these upright rods 266 has a cam roll 270 resting on a cam 272 secured to the cam shaft and each of the rods is provided with a slotted guide 274 offset from the cam roll and surrounding the end of the cam shaft 60 outside of the cam 272. It is possible, therefore, by a single rotation of the cam shaft to cause the raising and the lowering of the baffle plates in a desired timed relation to the other operations of the machine.

In order to lift the work out of the machine at the completion of the cycle, the ejector 28 in the form of a grid received in grooves in the work support '16 is mounted at the upper end of an upright operating rod 276 (Figs. 1 and 2) guided in a truss 278 bolted to the frame of the machine. The upper end of the ejector rod 276 passes through a raised cbllar 280 at the center of the receptacle 22 so that there will be no leakage of cement at this point. At the lower end of the ejector rod 276 is a slide 282 which is guided by depending portions 284 of the truss 278 and which is pivotally connected toa pitman 286. This pitman is secured to a crank 288 on a stub shaft 290 mounted in a standard 292 bolted in the frame of the machine and the stub shaft 290 carries a pinion 294 meshing with a large gear 296 freely rotatable upon the cam shaft 60. The gear 296 is held against lateral displacement on said cam shaft by engagement of its hub with plates 298 and 800 each of which is pinned to the cam shaft and operates to control the movements of the gear 296. The plate 300 carries a pin 302 spring-pressed outwardly away from the gear but capable of being pushed into engagement with a shoulder on said gear by means of a cam bracket 304 which is bolted to a part of the standard 292. Thus, during a limited portion of the rotation of the cam shaft 60, the pin 302 will be forced into engagement with the gear 296 to cause a partial rotation thereof. Because of the gear ratio between the gear 296 and the pinion 294 this limited movement of the gear 296 is effective to cause a complete rotation of the crank 288, thereby to move the ejector 28 upwardly to carry a shoe out of the machine and then to drop said ejector back into position within the grooves of the work support 16. Atthe completion of the limited movement of the gear 296 which is required for this action, it is stopped by a spring-pressed pin 306 pressed inwardly against said gear by a cam face on the plate 298. After the gear 296 has stopped, pressure on the pin 306 is released.

In the operation of the machine, assuming that the receptacle 22 has been supplied with cement and that the operator has placed a shoe upon the work support 16, depression of the starting treadle 86 will cause engagement of the driven portion 62 of the clutch with the constantly rotating gear 58 thereby to give the cam shaft 60 one complete revolution. It will be understood that the motor is operating constantly during the use of the machine and accordingly that the spraying devices 24 are being driven continually to pick up cement from the receptacle and project it in the form of a fine spray. The spray will be intercept-ed inwardly by the bafile plates 26 and outwardly by the receptacle 22. After the cam shaft is started, however, the shields 18 and 20 will be moved into engagement with the shoe by the operating levers 242 acting through the various slides and the intermediate levers 160. The baffle plates 26' will then be lowered so that the projected cement may be applied to the exposed foxing area of the shoe without danger that any of the upper portion of the shoe will become coated and with assurance that the range of the foxing area will be exactly determined and a heavy coating of cement applied. After a suitable interval the baffle plates will again be raised and the shields opened whereupon the ejector 28 will operate to raise the shoe out of the machine and then to drop back in its original position in the grooves of the work support 16.

It will be understood that, in various aspects, the invention is not limited to embodiment in the particular type of machine shown and described, or to the performance of the particular operation referred to.
