DEVICE FOR ATTACHING BUTTONS TO GARMENTS.

SPECIFICATION forming part of Letters Patent No. 243,303, dated June 21, 1881.

Application tiled March 11,1881. (No model.)

To all whom it may concern Y Be itknown that. I, CLARK M. PLATT, of Vaterbury, in the county of New Haven and State of Connecticut, have invented a new and Improved Anvil for Attaching Buttons to Garments; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification.

This invention is in the nature ofan improvement in a device for sett-ing the metallic rivets or shanks of buttons; and the invention consists in an anvil forsetting the metallic shanks or rivets of buttons, provided with jaws, in combination with a spring, the jaws being of cam shape, and constructed to have vertical and lateral play, as is more particularly hereinafter described.

In the accompanying sheetofdrawings, Figure l represents a plan or top view of my im'- proved anvil Fig. 2, a front view of same, partly in section; Fig. 3, a side vieu` of same; Fig. 4, a side view of my anvil, with jaws and spring removed; Fig. 5, a vertical section of same through linea? Fig. l Figs. 6 and 7, front view and vertical section through line y y, Fig. 9, of modified anvil, with spring passing through interior of anvil; Figs. Sand 9, side and top views of same.

Similar letters of reference indicate like parts in the several figures.

In securing buttons with metallic fastening Shanks or rivets to garments, it is essential that the head of the rivet or eyelet should be supported iirmly onan anvil while its other end is upset within the button, which operation is more particularly described in reissued Letters Patent granted to G. J.I Gapewell, February 23, 1869, N o. 3,307 5 but in order to hold the rivet in place on the anvil itis necessary that some yielding device, such as elastic jaws, should be employed, so that while the rivet may be held to the anvil durin g the riveting'process it may also be readily detached from the anvil and jaws after the riveting is completed and the button is fastened to the garment. Heretofore this releasing has been done by hand by slipping the rivethead from between the jaws. By my invention, however, the releasing of the rivet-head is automatically accomplished, and much time therefore saved.

To that end I construct my anvil A with recesses a on two of its sides, with jawsB tted within the same. These jaws have cam-shaped upper ends, b, which overlap to some extent the upper surface of the anvil, as shown in Figs. 1, 2, 6, 7, and 9. Fitted in a groove, c, and surrounding the anvil and the sides ofthe jaws B, is a spring, C, of sufficient elasticity to confine the sides of the jaws B snugly in contact with the recesses a and sides of the anvil, in which position the overlapping ends resting firmly upon the upper surface of the anvil A. A needle such as is ordinarily used for passing tubular rivets into garments is placed within the rivetor eyelet, the garment h forced over the needle and the shank of the eyelet until the shank protrudes through the garment. The button 7c is next placed over the end ot' this protruding shank, and up to this time theelastic force of the overlapping jaws B has held the rivet firmly in position and tightly against the anvil. The settingplunger l now descending upon the face of the button, the tubular end of the rivet or eyelet, by reason of the cone on the endof the plunger and the depression in the face of the button, is split or spread within the button-shell, uniting the two iirmly together 5 but as the plunger descendsto accomplish this riveting it at the same time forces the garment firmly against the upper and projecting surfaces of the overlapping jaws B, forcing these jaws downward, which operation is permitted by the elliptical openings e, and as these jaws are in this way forced down the cam or curved shape b of the jaws causes the jaws to spread outward sufciently to release the rivet-head from their grasp, so that the rivet is instantly and automatically removed from the anvil to make room for another, to be proceeded with as before, the jaws being restored to their' normal position, after releasing the rivetg by the elastic force of the spring C acting against the shoulders o of the jaws.

By constructing the jaws so that they may have a yielding vertical movement they cannot punch a hole in the garment when the plunger descends to clinch the rivet, nor will they be broken, as is the case with jaws imrnovably xed to the anvil 5 besides, by their elasticity, the rivet-heads are more readily inserted by the operator between the jaws without the danger of cutting the lingers, as in anvils with stationary jaws.

Instead of employing a surrounding` spring, C, as shown in Figs. l, 2, and 3, and as above described, a spiral or elastic spring may be inserted through an. opening in the body ot' the anvil and connected to the jaws in any desirin combination with a spring, substantially as and for the purpose described.

2. In an anvil for upsetting rivets and eyelets, studs xed to the sides thereof, in combination with jaws having overlapping ends and elliptical openings in thelegs of the same, whereby vertical and lateral movement is secured, substantially as and for the purpose described.
