l 4.9 Claims.'

This invention relates to machines by which Work-pieces are coated, it being particulariy concerned with the application of, the coat-ing in connection with another operation. 'An' example of work for which this machine is well adapted is the cementing of the breast-flaps of shoe-,soles for the purpose of effecting their'temporary Aattachment to the sole-bodies 'from which they have been divided. Another fornfof theinvntion, specic to the present case, is made the subject of an application for Letters Patent of the United States. led Simultaneously herewith and num,- bered 8,00%, the title oi which is Coating-applying machine. i Y

It is a common practice4 in connection with womens shoes to split from the grain-side oi a sole a thin flap, which may later b e cemented to the breast o f a heel attached to the shoe, to furnish a covering for ysaiglbreas't.A Between the splitting vand breast-covering operations, yarious other manufacturing steps occur involving the sole. For example, in acement-process "shoe, there are the operations of shank-reducing, roughing of the flesh-side, lthe application of cement and then a solvent thereto, and the pressing of the soleupon the shoe-bottom. While this is being done, the rather frail, loose breastflap is obviously liable to injury, as by creasing or tearing. It is an object oi ymy invention to guard against 'diiiiculties of this character, and with this in view l have provided a machine which may, among its various uses, be employed totemporarily attach a breast-nap to the opposedsurface of its sole, to be separated therefrom'when it is to be cemented to the heel-breast. As above indicated, this aitacnment may be associated with other operations upon the work, as thespiitting of the flap from the sole-body. This is not, however, an essential part of the present invennon, which, more broadly, is directed i1-@the apttachment ofthe workportions to one another;

For the attainment of my object, T combine means acting between opposed surfaces, as of a sole-body and a flap divided therefrom, to turn the flap away from the body while it is supported to receive the turning action, and means for applying cement or other coating material to the separated surfaces, in the present instance to the surface of the flap. Thereafter, the work is'acted upon by means which brings the work-portions together and applies pressure to them. The flap is thus held against mutilation, adhering to the sole-bo'dy until its separation for operations upon it is desired. To facilitate this separation, the coating is applied over less than the entirelaica' (ci. raf-17) of the surface, leaving a portion which may be grasped by the operator for its detachment. The application of the coating may be by such a de-j vice as a nozzle, and this I have shown as mounted upon a carriage arranged to reciprocate along a table upon which the work is supported. With the nozzle, or other applying device, upon the carriage, a receptacle for the coating material,` a pump for causing the delivery of said material, and a pressure member for 'the work may be mounted. A movement of the nozzle to bring it intoV and out of applying relation, together with movement of the pressure member and actuation of the pump, are preferably causedor controlled', either by the reciprocation of the carriage or by a raising and lowering of the table. The attaching voperation is most effectively carried out in connection with another operation Vupon' the Work, an eilicient procedure being to combine the attachment with the division or splitting 'of the flap from the sole-body. For this purpose, "a splliting knife is best mounted upon the carriage, this knife producing its out during relative move ment between said carriage andthe work in one direction and while the work-Supporting table is in its elevated position. As the knife divides the flap, it turns it back from the sole-body, giving the nozzle or other applying device access to the j ust severed surface to effect its coating. An 'abutment upon the carriage, along which the flap is thus turned, holds said ap for the action of the nozzle upon it. During relative movement between the operating elements and work in another direction, as, for example, vone'opposite to the direction of movement during the making of the cut, the oppos'edsurfaces "of the ilap and sole-body are brought together and pres-- sure applied thereto.

A single embodiment of my invention is illus.- trated in the accompanying drawings, in which Fig. l is a broken side elevation of the improved machine with the elements in their normal po sitions;

In Letters Patent of the United States No. 1,224,918, Furber, May 8, 1917, is disclosed a machine to which my invention may advantageously be applied. The more essential elements of the apparatus of the patent and the manner in which they co-operate are as follows: Upon a base Ill is mounted an actuating member I2 (Fig. 3) from the opposite sides of which project rolls I4. These rolls lie within inclined slots I6 in the sides of a work-supporting table I8. By a spring 20 (Fig. 2), interposed between a portion of a base and a lug depending from table, said table is l urged normally to the left as viewed in Figs. 1 and 2 of the drawings, the interaction of the rolls and slots causing it to occupy at this timeits lowest position. Movable upon ways 22 extending longitudinally at opposite sides of the table is a carriage 24, and xed transversely upon it are a splitting knife 26 and a gage 28 (Fig. 5) which is a mutilated cylinder adjustable about its axis to determine the depth of cut of the knife. A rotatable operating member 30 is joined by a link 32 to the carriage 24 to reciprocate this over the table, and bears a cam-34, which, by engagement with a roll 36vupon the table I8, moves said table longitudinally suciently to raise and lower the table I8 on the rolls I4 transversely of the path of reciprocation of the-carriage. At the beginning of an operating cycle a sole S to be split at the heel-portion to furnish a breast-flap s is laid upon the table, andthe machine started in operation. The cam 34 shifts the table to the right (Fig. 1) over the rolls I4 to raise it to splitting position, andthe -link Y32 moves the carriage 24 to the rightto cause the knife26 to divide the breast-flap from the body of the sole. The cut having been completed, the cam frees the table, which travels to the left Vunder the iniiuence of the spring2il.Y This lowers the table to relieve the work Vof the. pressure of the gage, while the link restores the carriage to its initial position, the splitting' operation having been thus completed.

To coat one of the divided surfaces with an adhesive and thus prepare forV the attachment of the two Ysurfaces to each other by pressure over the coated area, there is mounted upon'one of a pair of standards 40, 40, rising from opposite sides of the carriage 24, a cement-receptacle 42. Fulcrumed upon a bracket 43 depending from a bar 44 joining the standards is abell-crank-'lever 46, which, at its lower extremity, has secured to it arnozzle 48. The outlet-portion 50 of this nozzle is shown as curved forwardly toward the gage 28. It acts upon the work against the resistance to displacement offered by a curved abutment-plate 52, depending-from a cross piece 53 forming part of the carriage at the forward side of the gage. A spring 5I joining the bell crank 46 and hence the nozzle to oneof the standards 40 exerts its force to draw said nozzlel normally toward the plate. A exible pipe 54 connects the nozzle to a pump-cylinder 56 mounted at the lower portion of the lcarriage at one side of the base IU. A piston 58 operates in the cylinder, relative movement between'the two-being produced by contact of collars 60 and 62 upon the piston-rod 64 with normallystationary elements upon the base. This action will later be eX- plained. A pipe 66 delivers cement fromV the receptacle 42 to the pump-cylinder through a spring check-valve 68, as illustrated in Fig. 4, when relative movement of the cylinder and piston produces suction. Upon relative movement in the opposite direction, the drawn-in charge is forced -receive the split-01T flap s while the charge of cement is being drawn from the receptacle 42 into the pump-cylinder 56. During the rearward or reverse travel, the nozzle is to be moved in against the flap, which has been raised from the body of the sole above the knife and into proximity to the plate 52, and the cement is forced by the pump through the'nozzle upon the inner face of the flap. Further, the cemented flap is to be pressed downV upon the sole-body to eiect its adhesion thereto. These operations are accomplished in the following manner:

The upper arm of the lever 46 is united by a link 10 to a lever 12 Yfulcrumed at 13 on the carriage 24. This level' carries two rolls, one, 14, turning about thepivotal connection of the link, and the other, 16, rotatable on av stud secured to' the lever between its extremities. As best shown in Fig. 1, in the initial position of the carriage 24 the rol1v16-rests upon the upper edge of a cam-plateg18. Thisplate4 is adjustable along the path of the carriage by slot-and-screw connections 19 to vary the time of its effect. The contact with-,the cam-plate so turns the lever 12 clockwise that the link 10 `correspondingly rotates the lever 4B, to .hold the nozzle separated from the plate 52 against theY force of the spring 5I. As the carriage advances in its forward cutting travel, vtheroll 'I6 reaches a downward inoline at the end of the cam-plate 18. Now, however, since the table I8 has been raised into itscutting position by the rolls I4 l and slots I6, an edge of said'table contacts with the roll 14 on the lever 12, so vthe inactive relation of the nozzle is maintained. This continues until that operating period illustrated in Fig. 2 is attained and after the splitting-off of the flap s has been completed. Now the table is lowered and the travel of the carriageis reversed. lAs the tableedge leaves the roll 14, the spring 5I carries the nozzle into engagement with the flap, which is backed by the plate 52. The bodily movement of the nozzle with the carriage applies a strip of cement along the center of the flap from near its Vjuncture to the sole-body to a point somewhat -removed from the free end, which end is to be left uncoated. lAt this time the roll 16 strikes and rides up the cam-incline 88, causing the lever-and-link-connections to swing the nozzle to its inactive position.l The elements finally assume the relation illustrated inFig. 1.

. As to the supply of cement from the receptacle 42 to the 4nozzle 50, inspection of Fig. 1 will show that the operating-cycle starts with the piston 58 in its iinal discharging position. As the carriage 24 travels to theright, the cylinder 56 and the piston firstmove together, their relation to each othernot changing. The piston-rod 54 passes through a perforated stop-lug 82 upon the base. When, at an intermediate point in the advance of the cylinder and piston, the collar 50 strikes the lug, it is retained thereby and the piston remains at rest whilethe'travel of the cylinder continues. This applies suction to the valve 68, opening it and drawing into the cylinder a charge of cement LLL through the pipe 66, as appears in Fig. 2. During the taking in of the charge, the valves 69 and 'H are held seated. At the completion of splitting travel of the carriage 24', the collar 62 has just passed a detent 86 pivoted upon the camplate 'I8v and urged into the path of the collar by a spring 86. The detent retains the piston-rod and piston against rearward movement, while the travel of the cylinder continues. This forces the cement out of the cylinder through the now opened valve 69, the valve 68 being closed by the pressure. Delivery of the cement to the nap through the nozzle in its activ-e position occurs, the amount being controlled by adjustment of the spring 15 of the valve 'I I, which may be caused to divert a greater or less quantity through the bypass 13. At the time the nozzle is removed from the flap by the engagement of the roll 7S with the cam-incline 80, said roll strikes the detent, which it overlaps, and lifts it from the collar 62. The piston now being free to travel with the cylinder, the discharge from the nozzle 59 ceases because there is no longer a force acting to expel the adhesive from the cylinder. The collar 92 moves past the detent, which is restored by the spring 86 to its normal position. The quantity of cement taken into the cylinder and the beginning and end of its expulsion may be altered by adjustment of the cam-plate 'I8 and the collars 69 and 62.

A portion of the length of the nap s having been thus coated, it is to be pressed against the body of the sole S to cause its adhesion. Shown as pivoted to turn about the same axis as the gage 28, and extending forwardly from the carriage 2t along the table I8, are arms 92 in the free extremities of which is rlxed a pressure-rod 92. Between the rod and its pivot-point, each arm has mounted to rotate upon it a roll 94 arranged for contact with a table-edge, against which it is drawn by a spring 96 uniting the arm to the base. Noting that the rod is farther removed from the pivotal axis than the rolls, and that the rod is consequently movable through a more extended arc, the relation of the peripheries of the rod and rolls is such that with the table raised during the cutting stroke of the splitting knife 29, engagement of said table with the rolls so positions the rod that it exerts no pressure upon the work. When, however, the table drops for the return travel, the rod is lowered into engagement with the wor-x (Fig. 6) and is dragged over it toward the ap s. This forces the coated under surface against the opposite sole-surface to effect adhesion.

To briefly outline the operation of the apparatus, and assuming that a breast-flap s is to be split from a sole S, with the elements located as appears in Fig. 1 of the drawings, the operator places the sole longitudinally of the table I8 with the heel-end pointing inwardly and applies power to rotate the operating member 39. The cam 34 and the cooperating rolls I4 and slots I@ raise the table, and the link 32 moves the carriage 24 over the sole, so a flap of a thickness determined by the setting of the gage 28 is split and left attached to the sole at its base. As this occurs, the flap is turned up over the inclined upper bevel of the knife between the abutment-plate 52 and the nozzle 50. Said nozzle is held spaced from the plate by the successive action of the cam-plate 'I8 and the margin of the table upon the rolls 'IS and 'I4,`respectively. The rod 92 is held clear of the Work by the rolls 94 resting upon the elevator table. A charge of cement is drawn into the cylinder 56 from the receptacle 42 under the control of the collar 60. The nap-cutting having been completed, the table is lowered, and, as it leaves the roll 14, the spring 5I urges the nozzle 59 downwardly against the flap near its base, forcing it against the plate 52. As the table falls, the rod 92 is drawn down upon the sole by the spring 9%. During the travel of the carriage 24 rearwardly, the knife is carried from beneath the flap, the piston 58 is retained by the collar 92 and the detent 84 and delivers cement from the cylinder through the nozzle upon the inner face of the flap, as appears in Fig. 5. Upon engagement or the roll 'I8 with the detent 84 and the cam-incline 89, the discharge is stopped and the nozzle is withdrawn from the flap. When the rod 92 reaches the flap, it forces it against the body of the sole. This last-mentioned effect is illustrated in Fig. 6. The carriage is brought at the close of the operating cycle to the normal position of Fig. 1. In the work thus completed a sufficient portion of the ap is so attached to the sole by the adhesive that its injury during subsequent operations will be guarded against, but the free end may readily be grasped by the operator and the remainder of the flap drawn away from the sole when such separation is desired.
