To all whom it may c ncern:

Be it known that I, FRED A. RUMNEY, a

citizen of the United States, residing at,

Somerville, in the county of MiddleseX and Stateof Massachusetts, have invented certain Improvements in EyeletingMachines, of which the followingdescription, in con-' nection with the accompanying drawings, is a specification,"like reference'characters on y the drawings indicating like parts in the several figures. I

" This invention relates to improvements 1n eyeleting machlnes, and more part cu larly to improvements in eyeleting machines of the type disclosed in Letters Patent of the United States, September 14, 1909, cation of George Goddu,

No. 934,066, dated tomachinesof other types or machines for setting other forms of fasteners, such, for lnstance as studs or rlvets.

An object of the present invention is to provide a simple and effective arrangement for retracting the punches and setting dies connected with a retracting lever which is actuated by a sprlng pressed plunger for retracting its respective punch or set and maintaining it out of engagement with the work. The compression springs for actu- 'atlng each of the plungers are lncased 1n a portion of the feed frame and are thus hidden from inspection. It has been found that these compression springs are liable to.

break or become slow in action from other causes and that on account of their concealed position the operator neglects to replace them until their complete failure results in a catastrophe to'the machine. The

present invention, however, contemplates a 7 novel construction and" arrangement ofparts which obviates the difliculties above discussed, and at the same timesimplifies the general organization of the machine and thereby reduces its cost.

To this.end,"an important feature- 0f the invention consists in providing single de- 1 vices for retracting both punches and both sets and in so locating such devices that they may be, at all times, readily accessible and .open to inspection. Preferably the punch Specification-of Letters Patent.

invention contemplates an arrangement of the anvil plate and work rest such that the acting surfaces of both are rendered substantially continuous, the occurrence of a space between them into which a part of the work could enter and become caught. As herein shown this'is accomplished by mounting on one of said thereby preventing members a uard late which-is arran ed to slide freely in a slot formed the other member. Preferably the guard plate may be mounted on the anvil'plate' by means of a long reduced shankand this construction the upsettin dies and cutting block may be retained in the anvil by having the shank passed through. them.

Setting devices or sets have been usually constructed of one piece of stock shaped to set the desired eyelets and uniformly tempered throughout. The present invention, however, contemplates the provision of a setting device having a short detachable and replaceable portion in which the die proper is formed, the die portion being shaped to vfit like a. cap over the end of the body portion of the setting device. This construction is advantageous in that the die itself may be formed of hardened steel While the remaining portion of the setting device may be left softer and consequently less brittle. The setting device may also be renewed at much less expense than formerly by merely replacing the portion in which the die is formed.

The features and advantages above set forth and others incident to the invention will be best understood and appreciated in connection with the following description taken in connection with the accompanying drawings in which,

Figure 1 is a view in elevation of the punching, setting and work uiding portions of an eyeleting machine embodying the present invention; Fig. 2 is a plan view l of the guide plate and anvil plate.

The machine shown in the drawings, like the machine of said patent, is organized and arranged to punch two holes in the opposite sides of the upper of a shoe and then to set two eyelets in those holes and to feed the work.

The principal features of the present invention, as already pointed out, reside in certain improvements in the various parts of this machine. Before proceeding to a detailed description of these parts it will be convenient to refer to the general mode of operation and relative arrangement of the machine. c The machine shown in the drawings hasa base 2 to which is attached the frame 4:

carrying the driven or operating parts and the work guiding mechanism. As in the patent, this machine comprises oppositely disposed punches P and oppositely disposed sets S arranged for reciprocation in bearings in a support or feed frame 6, with the anvil or die plate 8 also mounted in said support or feed frame, arranged between the oppositely disposed punches and eyelet setting dies. The feed frame and the devices carried thereby extend at an angle of 45 to the vertical. The clamping members or presser feet 10. are arranged to engage the work on the opposite sides of the guide plate 12, smoothing and guiding it to the setting dies.

In presenting the work to the machine punch the presser feet 10 yield away from the guide plate 8 allowing the opposite quarters of a shoe to be drawn over the opposite sides of the guide plate 12 with their edges against the edge guide 14: mounted on said guide plate. The machine is then set in. operation whereupon the punches first advance and v0 holes in opposite sides of the upper in alinement with each other, then the feed frame 6 rises to b ing the sets into the position previously occupied by the punches and eyelets are presented to the sets S which insert and clench such eyelets in the holes in the work. After the sets have clenched the eyelets in the work they are released slightly but still held in en gagement with the eyelets, and then the feed frame 6 is moved laterally to feed the materials the desired distance between two successive eyelet holes, the feed frame then makes its return or back feed movement bringing the punches back to their original positions and the operations are repeated.

In the accompanying drawings the actuat ing cams and mechanism for raising and swinging the feed frame 6 and the cams for actuating the set and punch operating levers 16'are omitted since they form no part of the present i vention but are similar to the corresponding parts shown in Tat entllo. 934,066 to which reference may had.

The operating levers 16 are actuated by cams to impart the working pressure to the punches P or to the setting dies 5 according as one or the other of these devices are brought into operative position by the feed frame 6. The punches P are each arovided with a forked projection 18 which the outer end of a lever 20 pivoted on the frame 6 by the pin 22. Each of the lovers 20 is provided with a rearwardly extending arm 24 and extending between the arms 2%- and having a swiveled connection therewith is a tension spring 26 which tends always to l.

raise the levers 20 for retracting the punches.

The setting dies S are each provided with a recessed projection or block 28 adapted to extend upwardly and rearwardly to clear the arms 3 of the levers 30 and are so disposed as to allow the springs 36 and to extend in a parallel relation along one side of the feed frame 6 where their condition may be readily observed by the operator and the springs easily renewed if not operating satisfactorily.

The guide plate 12 is 'slidingly mounted upon a fixed part of the frame and carries upon the position of the edge of the work with relation to the setting devices, the

rearwardly. In order that the operator may conveniently move the gages rearwardly prior to the introduction of each new piece of work for setting the lowermost eyelets with a wider spread than the other eyelets, the guide plate 12 is provided with an eye 44 to which is connectedone end of a flexi- The chain is guided over a guide-pulley .46 on the frame 4 and is attached to the upper end of a treadle rod 48 extending preferably to the heel end of the starting treadle (not shown) by which the guide plate 12, presser feet 10 and edge gages 14 may be shifted rearwardly. The guide plate 12 with the work clamped to it is moved forwardly to its normal position and limited in its motion by the pinion 42, which constitutes part of an automatic device for moving the guide plate forwardly, after the first or lowermost pair of eyelets have been set, said automatic mechanism being fully described in Patent No. 934,066 above mentioned.

The anvil plate 8 carries the cutting block 50 and the upsetting dies 52 cooperating respectively with the punches P and the sets S. In order to prevent loose portions of the work from getting caught between the workrest 13, which extendslaterally from the guide'plate, and the lower end of the anvil plate 8, a guard plate 54 is mounted on the anvil plate and arranged to slide freely in a slot formed in the work rest 13. Preferably the shank 55 of the guard plate 54 may be utilized to retain the cutting block 50 and the upsetting dies 52 within the anvil plate 8 by being extended through a transverse bore formed in these members. As shown in Fig. 2 the upper end of the shank is notched and the guard plate held in position by a locking screw set in the anvil plate. lVhen the guide plate 12 is shifted rearwardly by the treadle through the chain 45 the work rest 13 slides upon the guard plate 54 to a position nearer the anvil plate 8 than normally but is moved back to its normal position at the end of the first cycle of the machine by the pinion 42. The operation of the. anvil plate is, of course, unaffected by the shifting of the guide plate. During the feeding operation the guard plate slides toward the left between the sides of the work rest 13.
