a nis shoes.

ln the manufacture of canvas shoes havingrubbersoles andofthetype called tennisf shoes, itis the usual practice to secure a thin strip 'of unvulcanized gum rubber, termed a y1C foxing, around the periphery of the bottom of the lasted shoe prior to the application of the rubber sole.v This strip has been secured in place by means of a heavy, viscous ce` ment which commonly `is applied by hand, the voperator holding a brush filled With the cement in one hand While presenting the shoe thereto with the other hand and turning the shoe so as to present all portions of the area to which the foxing is to be applied to the brush. The foxing is then applied tothe cement coated foxing area after which the rubber sole is cemented to the shoe with its edge overlapping the foxing strip, and the sole and l'o'xingare vulcanized together.

The `proper appearance of the completed shoe depends largely upon the proper posif tioning of the foxing strip on the shoe,.the aim being to locate the strip so that all points in its upper edge are at auniform distance,

approximately a halfinch, from the bottom of the shoe. Furthermore, in `order't'o pro-v duce a commercially `satisfactory product, it is necessary for the stripe of cement to coincide at its upper edge 'accurately with the upper edge of the foxing strip. v In other Words, if the cement shows above the foxmg stripfthe appearance is unsatisfactory and if the foxing strip overlaps the stripe of cement, then the edge of the strip is not prop# erly secured to the shoe and the appearance not only is not satisfactory but there is danger of accidental tearing away of the strip On the other hand, in spite of these requirements, experienced operators have acquired` a skill such that the speed of their Work Ais very considerable.

One object of the present invention is to. provide a machine for applying cement to the foxing areas of shoes which will pro duce Work at a speedart least as great as the ports adapted speed obtained by hand Work and of more uniformly satisfactory quality.

To this end, and in accordance With a feature of the invention, the illustrated machine, Which is substantially automatic in its operation, is provided vwith an endless carrier havin@ a series of shielding shoe supto receive and to protect portions of a plurality of shoes and to transfer the shoes successively past cement-applying mechanism, the shoes being thereafter removed in turn from the carrier. Preferably, and as herein illustrated, the machine is also provided with a drying chamber through which the coated shoes are passed in turn to dry the coating suiiiciently so that the shoes ma be readily removed from the carrier.

i, s has 'already been brought out, the accursite definition of the upper edge of the coated foxing' area is important to the production of satisfactory work and in accordance with another feature of the invention, the illustrated shielding devices above referred to are constructed and arranged to protect the uppers of the shoes above the foxing areasfrom the application of cement While accurately defining the upper limits of the foxing areaso The shields may be in the/form of plates having shoe-receivin openings corresponding in outline to the s apes of the bottoms of shoes tobe cemented, the edges of said openings being curved vertically according to the 'vertical curves of the shoe bottoms, Vin order that the foxing areas defined by the shields will be uniform in Width around the shoes. In order to define accurately the up er edges of the foxing areas in shoes of dibrent sizes, Worh-sup porting shields having openings of different sizes are preferably provided, the illustrated work-supporting shields being detachably secured to the endless carrier so that they may be v leadily removed and replaced when desire Still another object of the invention is to provide improved cement-applying means by which all `forms of cement may bereadily projected in aspray on parts of boots and shoese It will be understood that the construction force set up by a rotating applying device of an apparatus which will b e adapted to handle not only cement of medium body but willbeequallycapableotsprayiiigthelieavy and viscous types of cement, which usually have been employed forVY the foxing areas of shoes, is attended With difficulty. Furthermore, the situation is rendered even more complex when employing cement .compounded ot'Water-dispersed latex, which will hereinafter be termed simply latex, because of the fact that, While latex is thin enough for dispersion in the form of a Ispray without great difficulty when the machine is first started, this action cannot be continued indefinitely because of the coagulation which is set up Whenever the latex is subjected to pressure or friction by the handling apparatus. In accordance with still another feature of the invention, the illustrated machine is provided With novel cement-spraying mechanism which utilizes the centrifugal to which the cement is delivered to break up the cement Iinto a spray for application to a shoe part supported in the range of the spray produced by said applying apparatus.

Because of the viscosity of certain types of cement, it is found desirable to make provision for restricting the delivery of cement by the cement-applying device, and in the illustrated apparatus a rotary cement-pro-v jecting member having a restricted delivery slit adjacent to its periphery is provided, the cement being supplied to said rotary member for 'delivery through said slit by the action of centrifugal force to break into a spray before it strikes the Work. Also as illustrated, a flat disk is mounted for rotation about an upright axis positioned along side of tli'e shoe supports on which are carried the shielded shoes. Cooperating with this disk is a funnel-shaped annular member overlapping the surface of the disk and having one of its edges adjacent to but spaced from the edge of the disk. This annular member cooperates With the disk to provide a restricted space in which cement is received for delivery and an annular peripheral slit through which cement is projected. In order to increase the disperson of the spray, the disk is tilted with respect to its axis of rotation. Preferably, a plurality of disk cement-applying devices are provided, the cement-applying devices being located upon opposite' sides of the Work support so that, as a shoe is carried progressively past the lcement-applying devices, the tWo sides of the shoe are coated simultaneously step by step. Preferably too,a receptacle is provided for catching surplus cement, and means is provided for returning the surplus cement to the spraying devices for reuse.

In its method aspec`t,vthe invention provides an improved method of spraying cement on the foXing area of a shoe, the upper portion of Which is surrounded by a shield to prevent the application of cement thereto,

whicliiseharactenzedbycausingarelative movement of translation between a spraying device andthe shielded shoe to present different portions of the foxing area to the spraying device. As herein exemplified, the method comprises placing a shoe in operative relation to a shielding device to protect the portion of the upper lying above the foxing area and spraying cement on successive portions of the foxing area until the Whole of the foxing area is coated.

In the drawings,

In order that a plurality of shoes may he readily presented successively to the cementing and drying apparatus of the illustrated machine, there is provided a conveyor in the 'form of an endless carrier 10 passing over suitable Wheels 12 and l-l ournalled upon opposite en s of a supporting frame 16. This endless carrier 10, as shown in Figs. 1 and 2, is made up of a'series of parallel links 18 pivoted at their ends on the axes of grooved rollers vE20. These rollers are received in correspondingly shaped recesses 22 in the end Wheels and rails 2-1 are provided along the upper run of the frame 16 which form 'tracks for the-rollersand thereby support the carrier and the shoes thereon at a predetermined level. The axes of alternate rollers 2() also serve pivotally to support side carriers Q6 having inturiied bottom flanges 28 at their lower edges and outturned lips 30 and 32 at fthe ends of their upper edges and resting on adjacent links when the carrier is traveling along 'the rails 24. The 'inturned bottoni flanges 28 of the side carriers Q6 are provided machine, viewed as in Fig. 1, and to remove.

tom ot a shoe, said shield being associatedwith the shoe itself and vsurrounding the shoe to protect the upper above the toXing area. The combined work supports and shields have cross-rods 48 and 50 extending across the opening 44 and upon which the bottom of the shoe rests and the edges of this plate at the opening are curved upwardly as at 46 (Fig.

2) with respect to the plane of the Work-sup-`A port so that, when a shoe is supported on the` rods 48 and 50, the edge of the opening 44 will coincide with the upper edge of the foxing area of the shoe as it supports a shoe positioned therein., With this form of work-support, it is only necessary for the operator to deposit one shoe after another inthe openings of the work-supports 40 at the left end of the them from the work-supports at the right end of the machine, the conveyor `being effective automatically to present shoes to theapplying devices and to remove them therefrom.

It will be understood that the openings`44 of the successive work-supports are shaped `alternately for right and for left shoes.

The application of cement to the shoes suc- A cessively presented by means of the carrier 10 is eiiected by projecting the cement from a pairof rotary disks 52 and 54. arranged upon opposite sides of the path of movement of the shoe and mounted in tilted position at the upper end of shafts 56 and 58 which are journalled in the frame 16 ot the machine and in the bottom of a tank 60. These rotary members 52 and 54 are driven at suicient speed so that they disperse the cement in the form ot a 'fine spray to all sides ot the axis of each vot them. By properl v proportioning the speed of rotation to thev character and viscosity of the cement, the

action of centrifugal torcewill cause the cement to be distributed in a fine film over the surface ot the rotating cement applying' device and this tilmvvill b e broken up into la 'fine spray by the resistance of the air as so'on as it leaves the disk. The apparatus, therefore, facilitates the projection otcement inA the form of a spray without any possibility of clogging the outlet opening of the cement applying device. The cementpwhich is not used is caught in the tank Oivhich is prefera-bly shaped so that the surplus cement will drain toVV an outlet pipe 62 from which it is removed by means of a suitable pumpv (not shown) and delivered again, for reuse, to

the disks through supply pipes 64 and 66, each of -Whi'cht'is provided with a control valve 68. The shafts 56 and 58 for the oppositely directed spraying devices are joined by means ot a crossed driving belt and power is supplied for rapid rotation ot the disks by means of an electric motor 72, here shown as directly connected to the shaft 56. It will be observed 'from an inspection of Fig. 5 thatadditional dispersion of the spray in fanshaped fashion above and below the plane ot the center of'rotation of the disks results from the tilted position of the disks upon their axes of rotation, this dispersion being sufficient to coat the whole vertical extent of the 'foxing area, which is indicated in that figure by the blackened portion 74 extending aroundl the corner of the shoe 76 as Welll as 4 lapping relation to the disks are provided which cooperate with the disks to form restricted spaces provided with restricted out-` let openings near the periphery of each disk through which the .cement will be delivered. As herein shown the guards 80 are funnelshaped'hollow frusto-conical members which aremounted directly Aupon the-disks themselves and held thereon by means ot suitable supports 82 with their edges adjacent to but spaced from the edges of the disks to form a'` restricted annular delivery slit adjacent tothe periphery ot the rotary disk. rllhc restricted partially enclosed spaces provided between the guards 8() and the disks 52 and 54 have inlet openings 84 through which cement is supplied by means of pipes 64 and 66 for delivery through the peripheral openings ot the rotary members.v`

The ends of the tank 60 are cut away as shown at 86 (Fig. 3) to provide a pathway above the cement in the tank along which the successive shoes may pass, and covers 8S and 90 (Fig. 2) are provided which extend from the outer edges of the tank to the tracks 24 thereby partially to cover the tank outside ot the pathway of the conveyor 10. It will he noted that the space between the tracks is practically covered by the successive work-supports 40 associated therewith, thereby givinglittle opportunity for the scattering of the cement spray into the open air. If desired, the movementof the endless carrier may be' effected by means of power supplied from. the same motor 72' and to this end,` there is shown in Fig. l a worm and gear drive 92 for a counter shaft 94 journalled in the frame l'which is connected by a sprocket. and driving chains 96and 98 to the end wheel l2. f

lt will be observed from an inspection of Fig. v4 that the rotating disks 52 and 54,

l bers or annular guards 80 mounted in overthrowing a spray horizontally in all directions, are effective to coat both sides of the shoe simultaneously as the shoe moves along the pathway between said disks. The toe end will be coated as the shoe approaches the disks, while the heel end will be coated as the shoe recedes from the disks and the upper edge of the coated area will be accurately defined by the co-action of the shields 40 with the shoes.

After the shoes are coated, they are carried through a dryingehamber 100 provided with suitable heating means, such as stream pipes 102 and having entrance and exit openings which are protected by flaps 104 and 106. By means of this arrangement, a sufficient proportion of the moisture or solvent in the cement is removed so that the shoes may be readily handled as they emerge from the drying chamber and be removed by the operator by lifting lthem in turn as indicated by the arrow 110.
