Fig. 8 machine by means of arms 0 0 the former extending out from the frame a and the latter from a tubular standard or guide 0 projecting up from the end of the bracket 0 which is curved, as shown. When seen in end elevation, the work plate lies in two planes, one portion 0 being higher than the other 0 and connected thereto by a bend c. It is formed with a slot 0 for a purpose to be described, said slot lying in each of said portions c 0 The machine is provided with two sets at d, one above the work-plate projecting downwardly and the other below the work-plate projecting upwardly. Theyare in alinement and are adapted to sim ultaneously reciprocate vertically in opposite directions. Each set is provided with a spring-tensioned pin d to enter the eyelet, and they are mounted in setbars (1 (1*, respectively. The bar (i is slidably mounted in the overhanging arm a, before referred to, and the bracket d while the lower set (I is mounted in brackets 0 d projecting from the end of the frame a The brackets (Z extend from the rear side of the machine forwardly, as shown in Fig. 2, being curved to escape the mechanism for reciprocating the set-bars.

The last-mentioned mechanism consists of two horizontally-arranged shafts c e, journaled in bearings in the frame a and each having on its projecting end a spur-gear e or e", intermeshing with and driven by a similar gear 6 on the main power-shaft Z). On its end the shaft 6 is provided with a crank e connected by a connecting-rod c with a block a", secured to the upper set-bar (1 there being a guide-rod c secured at its ends to the brackets a d and passing through the block 6 to prevent the set-bar from binding. The shaft 6 is provided with a similar crank 6, link e and block a sliding on the guidebar a, and the parts are so arranged and timed that the upper and lower sets are operated simultaneously in opposite directions.

The stationary set or anvil with which the two movable sets coact may be described as floating and is indicated at f. It is secured to a bent lever f, fulcrumed at f on the frame, (see Fig. 12,) and is adjustably held thereon by screwsf being located above the lower portion 0 of the work-plate. The operative end of the anvil is provided with a wedge-shaped finger f and it is shaped on its top and bottom surfaces to engage and roll backward the skirts of the eyelets engaged by the movable sets. On the end of the le- Ver f there is a roll f running against a cam g on the main power-shaft b, so that as the shaft revolves the anvil is'moved into and out of the path of the movable sets by the aid of a spring f, as will be subsequently described.

The punching device comprises a punching-block h, which is setin the end of an arm h, extending toward the end of the machine and then rearwardly, as shown in Figs. 1 and 3, said arm forming a part of the vertical rock-shaft 71, j ournaledin front of the machine by adj usting-screws h It, passed through lugs h5 h on the frame, and having their conical ends extending into similar sockets in the ends thereof. The screws are provided with lock-nuts 71 by means of which they are held in place after being adjusted. Fulcrumed upon the rock-shaft h is a punch-lever i, the free end of which projects toward the end of the machine and rearwardly and is equipped with a punch t" in alinelnentwith the punchblock h. The punch-block h projects upwardly into the slot 0 in the work-plate c, and it and the punch are adapted to move longitudinally of the slot to feed the work, the movement of the rock-shaft and the upand-down movement of the punch-lever being accomplished by the same device.

The punch-lever'iis bent, as shown in Fig. 4, and the semispherical end thereof (which I hereinafter term the traveling member) projects into a cam-groove j in a cam-block j, mounted in a bracket 9' secured to the front of the machine. Through the block is passed a shaft 7' having on its end an arm ,7' which is slotted at 3' to permit the passage therethrough of the end of the punch-lever, as shown in Fig. 7, the other end of this shaft being journaled in a yokej formed on or secured to the block j. There is a mutilated or stop pinionj on the shaft, which is adapted to be intermittently actuated by a stop or mutilated gear 9' on the main shaft 1). The cam-groovej is substantially rectangular, so that when the pinion j is caused by the gear j to make one complete rotation the punchlever is first swung upon its fulcrum 11 toward the block to perforate the work, and then the set-lever and the rock-shaft are swung about the axis of movement of the latter to move the punch and the block longitudinally of the slot 0 in the work-plate to feed the work forward, after which the punchlever is again swung upon its fulcrum to release the work, and the punch and block are then carried back to their normal positions, where they remain quiescent untilthe next heel is to be punched and while the eyeleting operation takes place.

To free the work from the punch, I provide a cast-offj through which the punch extends and which is mounted upon the end of a sliding pin 7, encircled by a spiral springj, as shown in Fig. 7. The cam-groove may be varied in shape to increase the movement of the punch or the punch and block, as will be readily understood.

I have stated that the work is fed by the punching device, and it is evident, therefore,

plate 0'. A spiral spring 10 encircles the bar and has its ends pressing against the presserfoot and the under side of the bracket d whereby the operative end of the presser-foot is held with yielding pressure against the work-plate, the degree of pressure being determined by the position of a collar secured tothe upper end of the bar by a setscrew 70 and normally resting upon the upper side of the bracket 01 as shown in the lastmentioned figure.

The lower end of the bar 1:, projects downwardly from the bracket 0 and rests upon the end of a lever k fulcrumed at 10 upon the rear side of the frame and having its end k projected forwardly, as shown in Fig. 3, so as to be connected by a link 70 to the heel portion of the treadle, with the toe portion of which the arm 6 of the stop is engaged.

By depressing the heel end of the treadle the lever k may be swung about its pivot to raise the presser-foot for the insertion of'the work. In order that the work may be advanced, the presser-foot is raised intermittently and automatically by a cam is on the shaft e, which engages a roller is, journaled between lugs 10 on the end of an arm [c projecting forwardly from the lever 10 The parts are so timed that the 'presser-foot is raised long enough onlyfor the punching device to feed the work forward, after which it immediately descends and engages the work, while the said device returns to normal position.

For the purpose of feeding theeyelets to the two movable sets I mount the hopper Z, from which the two raceways Z Z lead downward, upon a bracket Z which is secured to a slide 1*, movable in guides Z Z on the rear face of the frame a The slide Z has on its end a roller V, which extends into a cam-.

groove g in the cam 9, whereby when the power-shaft is rotated the hopper is fed forward and returned.

The chutes or raceways Z' Z lead from op posite sides of the hopper, the former extending downward to a point below the workplate and the latter being given a half-twist and ending in a plane above the work-plate, as shown in Fig. 2. The delivery ends of the chutes register with each other, and when the slide l is moved forward also register with the spring-pins on the ends of the movable sets, whereby when the sets move toward each other they each take an eyelet from one of the chutes, after which the chutes are retracted or withdrawn.

The hopper is provided with the usual agitator (not shown) on the end of a shaft m, extending through the bottom thereof and equipped with a crank m, by means of which it is rotated, power being applied by a connecting-rod (not shown) to the crank from another crank m on the end of a shaft m which has on its end a gear m intermeshing with the gear 6 The operation of the machine is as follows:

The upper is folded along a central line, so as to bring together its two forward edges, which are to be eyeleted. The corners are accurately registered with each other, and after the presser-foot is raised the work is laid upon the work-table with the edge against the guide u thereon, the anvil being inserted between the two layers, as shown in Figs. 9 to 11, inclusive. The machine is then set in motion by depressing the toe end of the pedal to disengage the stop-arm b from the latch b to permit the latter to engage the rotating pulley b. As the power-shaft 1) begins to rotate the gear j imparts a single rotation to the pinion 9' to cause the punch to perforate bothlayers of the work and feed them rearward, the cam 10 at the same time engaging the lever 10 so as to raise the presser-foot until the work has been fed forward the proper distance. As the punch feeds the work the anvil is moved back by the cam g into the position shown in Fig. 10; but as the punch-returns to its normal position the anvil is immediately moved so as to register with the sets, as shown in Fig. 11. The chutes or raceways are then advanced to bring their delivery ends into alinement with the sets, and the latter are caused to approach each other and to each take aneyelet from the chutes, which are then returned to their normal positions. As the sets approach each other the pins 01 engage the anvil and are held stationary, while the sets continue their movement until their ends engage the eyelets and forcing them-through the apertures in the edges of the uppers spread the skirts thereof against the anvil. Afterward the sets are returned to normal position, and the punching device is again actuated to punch and feed the work. By this arrangement it will be seen that the two edges of the upper are punched and eyeleted simultaneously and that therefore the holes accurately register with each other. The two movable sets being operated simultaneously receive each others thrusts,so that the anvil is only pressed between them and does not receive an unequal pressure to bend it upward or downward.

The invention in addition to the foregoing features includes mechanism by means of which the feeding movement of the punching devices may be varied to increase or decrease the spaces between the eyelets. It is frequently desirable to place the eyelets near together at the lower portion of the upper and those near the top relatively far apart,

grooves in its side edges to receive the tongues projecting inward from the arms 71. n on the part a. A yoke 71 is secured at its ends to the ends of the arms n and is provided with a roller of, engaging a cam-wheel n on the shaft 91 The movable member or part n has dowel-pins a projectingloosely into sockets in the stationary member, and springs are coiled about said pins to force said members apart, when the member n is permitted to move. The cam-wheel'nfihasaseries of studs or teeth a which are engaged bya pin 11 on the shaftj once during each rotation of the last-mentioned shaft. Thereby the cam-wheel is rotated step by step. There are as many studs or teeth a as there are eyelets, with short spaces between them, and the recess in the cam n is so arranged that when the last stud is engaged the roller n enters the recess and the springs force the movable members away from the stationary member to lengthen the cam-groove in the block 72. The pin n then rotates without engaging a stud or tooth on the cam, for there is a wide space between the first and last studs, and consequently the remainder of the eyelets in the upper are spaced far apart. \Vhen the upper is fin ished and another is .placed in the machine, the operator draws downward upon a link or rod 0, which is connected to an arm 0', rigid upon the shaft 71', and as the cam is frictiontight upon the shaft the cam is advanced one step to draw the movable member 07. back against the member 07. to shorten the groove and to bring a stud into position to be engaged by the pin at.

It is obvious that the machine may be moditied in many respects without departing from the essence or spirit of the invention.
