Application and. my a, 1919. Serial No. 294,421.

A particularly valuable advantage. at-

tained'by my present improvements consists in the adaptability of my mechanism to the piercing of fabrics, soft leather or like yielding material, where 1t 18 desirable to retain the full strength of the material and'to avoid cutting or damagingth fib e thereof.

. My improvements may desirably be embodied in the class of punching and eyeleting machines described in prior Patent $51,120,989, dated December 15th, 1914:, wherein the punch and set are arranged permanently to be in axial alinement and in which a support is moved beneath the punch and set to insert an eyeletin the ma terial,'the actuating members in my improved machine being substantially the same. I

Important features of my invention coniprise means for piercing the material with a pointed punch, means for supportingthe material while being pierced, and means for retaining the eyelet to the punch until the setting-of the same in the material is completed.

The described and other features ofmy inventionare illustrated inthe accompanying drawings wherein like reference characters are applied to the corresponding parts in the several views. I

14L is a side elevation of a complete machine, showing meansfor operating the several members: some parts'being' shown broken away, and some in section.

The operating parts of these-improvements are mounted upon a supporting frame a upon which is slida'bly mounted the plate The/frame (1) isrecessed to receive the anvil (3) and the plate (2) is provided with a clearance recess (a and channeled to receive the 'slidable supportjaws (5,, 5) which are retained in their Leaf springs (7,7) fastened to the plate (2) compress j the supportjaws (5,5) together.' The supporting jaws (5,5)- are shaped on their abutting ends to conform to the shape of the punch which is slidably located within the set (9).- The punch (8) is formed to receive an expanding spring (10) whichis provided withlips adapted to retain an eye-- let on the punch when in expanded position and release it when compressed. r a

I Referring now to 14:, wherein there is l i illustrated means for actuating the described members in their operations as follows: Motion may be imparted to the pulley 13, which is adapted to engage with and rotate the shaft 14, upon which is secured the disk 15, which is grooved on its sides with the cam tracks 16, and 17.

The punch 8, is secured to the punchplunger 18, which is connected by the studs 19 and the connecting link 20, to the lever 21.

The lever 21 is pivotally mounted at 22 upon the frame 1, and is provided at one end with a roller 23, which engages with the cam track 16, formed in the disk 15, which when rotated imparts the afore described movements to the punch 8.

The set 9 is secured to the set-plunger 2% which is connected by the studs 25 and the links 26 to the lever 27.

Thelever 27 is also pivotally mounted at 22 upon the frame 1, and is provided at one end with a roller 28 which engages with the cam track 17, formed in the disc 15, which when rotated imparts the afore described movements to the set 9.

.Upon the shaft 14 is secured a disk 30 having a crank stud 31, which engages with a cam slot 32- formed in an arm 33 which mav be pivotally mountedupon a stud 34 erected on the frame 1.

Upon the slide 2 is erected the stud 35, which engages a link 36 connected to the arm 33 by a stud 37. Thus when the disk 30 with the crank stud 31 is rotated, the crank stud 31 moving in the cam slot 32 is adapted to rock the arm '33, and by means of its connecting link move the slide 2 with the supporting jaws 5 to or from beneath the material being operated upon.

The operation of the described mechanism in piercing a hole in the material and setting an eyelet, or like article therein is as follows:

The material supporting jaws (5, 5) being in alinement with the punch (8) and set (9) the material is placed thereover, an eyelet is impaled on the punch (8) and with the punch and set (9) positioned relative as 1 shown in Fig. 2 the punch operates to pierce the material and the set then further de scends to push the eyelet through the material into the position shown in Fig. i.

The punch (8) andset (9) are now elevated sufiiciently to remove any pressure on the eyelet and the material and the plate (2) with the supporting jaws (5, 5') is withdrawn from under the material, the jaws ('5, 5) yielding from the eyelet, thus bringing the anvil (3) into co-acting relation with the punch (8) andset (9) which are now brought down respectively to guide and set the eyelet to the material-as shown in Fig. 5.

- The retaining spring (10) in this position from the material, thud completeing the operation.

It will be noticed that the jaws (5, 5) are so formed as to support the material at the entrance of the point of the punch. and by yielding laterally continue such support throughout the operation of piercing the material.

A form of punch particularly adapted to pierce material is shown in Fig. 11. A further advantage of this form of punch is that in piercing material over a simple supporting member as shown in Fig. 6, the material is apt to wedge and remain therein unless the punch is grooved as shown, the groove acting to free the material from the supporting plate 6.

While I have shown and described an approved embodiment of the features of'niy present invention, it. will be understood that many modifications of the various features thereof may be made without departing from the scope of mv invention. For instance, as will be understood. the piercing yielding jaws 5) will cooperate with the eyelet and are suitably formed with inclined abutting faces (11, 11) so that the engagement therewith of the eyelet will cause the jaws to yield in the manner heretofore described.

it is therefore intended that all matters herein contained shall be interpreted as illustrative and not in a limiting sense.
