APPLYING APPARATUS. i

Application filed August 3, 1922. serial No. 579,443.

'lihe present invention relates to apparatus for the application of fluids to shoe-parts, and especially that for blacking' or staining the edges of soles.

Objects of my invention are to provide such an apparatus by which the application of the stain or other fluid may be made rapidly, uniformly and without waste.

In the attainment of these Objects, as a feature oi the invention, I combine with an applying member means movable into and out of co-operation with it for delivering the ll'u id' to be applied, and means governed by the Work for controlling the delivery of the fluid. By this, as an incident to an act performed by the operatorfor another purpose and without giving consideration to the controlling efiect, the delivery to the applying member may be made only at the times or in the quantities desired. ihsherei'n illustrated, a delivering member travels in a stain-receptacle and the amount of stain delivered to the applying member, the latter preferably being a rotatable brush, may be governed by moving the delivering member toward and from the brush, as by a movement of the re ceptacle. I prefer to effect the controlling movement of the delivering member through its connection to a movable Work-gage. In addition to the movement through which it exercises control of the delivering member, the normal position of the gage may be varied, and, as illustrated, there is a capacity for adjustment in av plurality of directions. One of these adjustments may be in the direction of the controlling movement, adapting the apparatus for operation upon shoes having dillerent degrees of sole-extension, while another adjustment may be toward and from the brush, altering the width of the sole-edge over which said brush operates. Tliis last adjustment permits the edges of white-stitched soles to be stained without soiling such stitching.

its another feature oi the invention, there is provided an applying member rotatable about an inclined axis and having a conical applyin-g'surfa'ce. At itslowermost portion, this surface is substantially horizontal, to adapt it to act upon the work, while with the opposite approximately vertical side 'co-oper'at'es means for delivering a coating fluid a spaced a substantial d istauce from the point of application of the work and out of the range of movement of the latter. As illustrated, the applyingmember is in the form of a brush, and co-operating with this brush is a Wo-rkgage, movable in a plane substantially at right angles to the applying surface. Preferably, the brush has a conical head, along which the gagemoves. The

brush is shown as rotatable about an inclined axis, the applying surface being approximately horizontal, The gage; is adjacent to an edge of the horizontal side, and fluid-delivering means is associated with the opposite side. \Vith this arrangement, all portions of the work operated: upon may be coated properly, without interference between the upper and the gage-and it also facilitates the delivery of fluid to the brush.

member 16. To provide for the correct in'i tial positioning of the, applying member with reference to its associated elements, it may be adj ustably mou'ntedupon the framearm, as by bolts 18 passing through the frame and also through vertical slots 20 in the support 1 1'. The downward limit of this adjustment may be more exactly determined by a screw 22 threaded through the support in a boss above one of the slots and having its lower extremity arranged to contact with the corresponding bolt 18. A check-nut 24- serves to retain the screw '22 in the position to which it is adjusted. Preferably, the applying member is in the form 01: a brush consisting of a head or support ing body 26, from which may project a ring of fibers 28-. Thebrush is fixed upon a spindle 3O journaled in an inclined position in the support 14', the inclination of this spindle befng downwardly and inwardly toward the frame, and being shown as lying at an angle of substantially degrees to the horizontal. Both the periphery of the brushbody and the applying surface 32 are conical, being approximately trusta of cones placed base to base. The brush-spindle is rotatable through bevel-gearing from a vertical sectional shaft 36, the portions of which are united for longitudinal movement to allow the brush-adjustment just described. This shaft 36 is journaled in the frame-arm, and is driven by worm-gearing 38 from a horizontal shaft 40 rotatable in the top of the frame and shown as connected directly to the shaft of a motor 4-2. I

Below and at the inner side of thebrush 16 is a stain-re eptaele 44 mounted to tilt about a stud 46 fixed in a horizontal position to the side of the frame, and passing through a passage which may be cast integrally with the opopsite walls of the receptacle. This receptacle is held upon the stud, for ready removal and replacement to permit its cleaning, by a washer 48 having a keyhole-slot 5O co-operating-with opposite slots in the sides of the outer extremity of the stud 16; The bottom of the receptacle is curved and at one side the upper portion is horizontal, as is indicated at 52, giv ing an opening convenient for the introduciion of the staining fluid, while the opposite side of the receptacle has an upward extension 54:, which at its top lies below the 1nner vertical edge oi the brush. Rotatable about a spindle 56 carried by the extension at of the receptacle is a sprocket-wheel 5i, and over this; and a small sprocket-wheel 60. rotatable upon an arm (31 lived to the stud 4-6, passes an endless stain-delivering member lm'nished by a chain 62. The arm 61 is preferably angularly adjustable ahoutthe stud to give the desired tension to the chain, it being lined in position by a screw 63 drawing together the sections of its divided hub. This chain is so located that it may travel, coiinter-clochwise. as indicated by the arrow applied to its outer run. so that one side will move from a point near the bottom of the receptacle upwardly l11t-O-])l01iiinity to or Contact with the upper. inner side 01 the brush 16 at a point ren'iove 'l a substantial distance from the point of application of the work so that there is room for manipulation of the latter. The travel ol' the chain is produced by a. pulley Sal turning about the spindle 46 between the receptacle l4 and the frame, and receiving power through a belt 66 passing over guide-pulleys 68, 68 rotatable at the upper portion of the frame, and then over a pulley 70 fast upon.

the upper extremity of the sectional shaft 36. Connected to or formed integrally with the pulley 64 is a sprocket-wheel 72, joined by a chain 74 to a sprocket-wheel 76 secured to turn with the sproeket-wheel 58.

The chain 6:2 is held normally out of contact with the brush to prevent the delivery of stain to the latter when no'work is in position to be operated upon. The accomplish this, the spindle 56 has, encircling its end a rod 78 guided in an opening in a bracket 80 projecting from the side of the trained-arm 10. Movement of this rod is allowed to an adjustable extent in either diection by pairs of nuts and lock- nuts 82, 82 and 84, 81, respectively above and below the bracket 80. N ear the lower end of the rod fixed a collar 86, and above this, encircling the rod and resting upon the col lar is a helical spring 88 supporting a sliding flanged collar90. Extending between the flanges of the collar 90 is one arm of a bell-crank-lever 92 fulcrumed upon the traine-arm and having-its opposite extrenr ity. connected by a link 9ato a lever 96 tulcrumed at its lower end upon the frame near the top of the receptacle. This lever 96 extends upwardly and outwardly to a point above the brush, and has an angular endportion 98, which is substantially vertical and reaches a point outside the brush. The portion 98 is adjustable laterally toward and from the brush by being pivoted at 100 to the body 96 of the lever, it being lined in its adjusted relation by. a screw 102 threaded into the lever andpassing through an arcuate slot 101%. in the portion 98. At the bottom of this lever-portioi'i is a divided socket to receive the shank 106 of a gage support 108. A screw 110 serves to draw the sides oil? the socket together to clamp the gage-support in place. Mounted to turn upon the support 108 is a purge-disk112 the axis of rotation of which is substantially horizontal. The inner side of this disk is concave, so that the periphery of the brush the fibers are approximatel; vertical, so.

that the entry of the brush into the (llfikconcavity is facilitated. The age-disk is dngned tor engageuiient with the crease of a shoe to be operated. upon. and to prevent the edge of the disk from entering too deeply into the crease and thus resisting the movement of the work over it, it is roi'inded, and the outer :l'ace 111- of the dish diverges rather abruptly from the 'ierlph'ery, giving a considerablethickness of material for contact with the upper face of the sole or of the welt at one side, and the material of the shoe-upper upon. the other.

Normally, the weight of the lever 96 and associated parts, aided by a spring 111 interposed between the lever and frame, holds the gage-disk 112 in its lowest position, and this, acting through the link 94: and the bellerank-lever 92, ur es the sliding collar 90 ing the chain 62 from contact with the brush by swinging the receptacle 44 about its stud ib. 's l here'i'ore, though the elevation of the stain by the chain from the receptacle is contii'iuous, it is not delivered to the brush under these conditions. l/Vhen the operator applies a shoe S to the gage-disk 1,12 and presses it upwardly, this disk, raised by its engagement with the crease swings the lever 96 about its fulcrum, and through the link 94- turns the bell-crank-lever 92 in a clockwise direction. The pressureoi the lower end of this lever ,upon the sleeve 90 transmits the movement through the spring 88 to therod T8, tilting the receptacle about the stud t6 and bringing the chain into yielding contact with the brush at a position upon the vertical face of the brush which is above the receptacle so that any drippings are caught thereby. Consequently,whejn the sole-edgereaches-the lowor portion of the brush, stain is being delivered by the chain to the upper portion, at a point out of the range of movement of the work and spaced a substantial distance l'rom'the point of application of the work. 'llhus the brush in its rotation, as indicated by the arrow, spreads such stain upon the edge of the sole. This application is in the direction of extension of the periphery, so there is no tendency to throw the stain toward the upper, which is also protected by the gage, or to overrun upon the sole. It should be observed that the inclination of the spindle 30 and that of the applying surface of the brush are such as to cause the latter at its lowermost portion to be substantially horizontal, whilethe adjacent face of the gage-disk at its periphery is approximately at right angles to this and its axis of rotation parallel thereto. This places the applying surface in such a position that the operator may most easily hold and present the shoe to it. The shoe sole is now rotated, under the guidanceoif the gage,until the entire sole-edge has been brought into contact with the brush. When the shanlnportion is rem-bed, the work may be tilted to keep the :ilpplying surface in the proper l'ransvcrfie relation thereto, without intcrt'cil'crme be ween the upper and gage-disk. The staini the edge having been completed, thee} -r" tor wages the work from the 54a which .umviine' the chain 62 away from the brush and stopping the feed of'stain. itccording to the amount which the edge oi lhe sic projects with relation to the upper, the support 108 may be adjusted vertically in its socket, or in the some direction as the movement which controls the stain-deliv y, so that the co-operation between the work and brush may be effected with minimum ello'rt. ltthe sole is attached to the welt by white stitching and it is desired that this s be kept free of stain, the portion 98 of tne lever maybe adjusted upon its pivotal coni'iection to so position the gage-disk with relation to the adjacent side of the 1 that the latter does not fully coat the v but leavesa very slight untreated margin. This insures against the flow of the ink over the edge of the welt to the stitching. The side of the brush opposite the lower applying area is nearly vertical, and this lends itself admirably to the co-operation with it or the stain-delivering chain, without interfering with the movement of the work during the operation. Moreover, the receptacle may readily be carried beneath this portion of the brush to present the chain to it and to receive the drip of the stain.
