EYELETING-MACHINE.

SPECIFICATION forming part of Letters Patent- No. 284,911, dated September 11, 1883,

Application filed August 6, 18%3.

To all whom, it may concern.-

Be it known that I, ALFRED J. SHIPLEY, of Waterbury, in the county of New.Haven and State of Connecticut, have invented a new Improvement in Eyeleting-Machines; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a side view; Fig. 2, a partial front view.

This invention relates to an improvement in machines for setting eyelets, with special reference to and is an improvement upon the machine for which Letters Patent of the United States were granted January 23, 1883, No. 271,049. In that patent the work-supporting bed or table is arranged upon one end of an arm, the said arm pivoted in rear of the table, and so that the table in its movement up and down vibrates upon the said pivot as its center of motion; hence the plane of the table is con stantly changing from its lowest to its highest position, presenting the work at constantlychanging angles. Again, owing to the vibratory or oscillating motion of the table, it'is difficult to retain that nicety and precision of presenting the work desirable in setting eyelets.

The object of my invention is to avoid the vibratory movement of the table and retain it always in a plane at right angles to the setting mechanism; and it consists in arranging the table on a slide invertical guides, and imparting to said slide an up-and-down movement in a line parallel with the axis of the setting mechanism, and as more fully hereinafter described.

The following is a brief description of the operative mechanism, sufficient to enable those skilled in the art to understand my improvement.

A represents the frame, adapted to be secured by a base, B, to any suitable support, and is provided at its upper end with inclined guides, in which slides the support 0 for the eyelet-hopper D, and the inclined channel, through which the eyelets pass from the hopper to the inserting and setting mechanism.

The setting mechanism is composed of the fixed anvil F, attached to an arm of the frame,

(N0 model.)

and provided with a downwardly-projecting punch, f, and in vertical axial line with this punch f is a yielding follower, g, arranged in a vertical movable plunger, G. To this plunger a reciprocating movement is imparted by means of a lever, O, which is hung at the lower end of the frame.

I is a bell-crank lever, (seen in broken lines, Fig. 1,) hung in the frame at J, one of its arms connected by a link, K, with a lug on the plunger, as seen in Fig. 1, broken lines, and its other arm with a cam or shoulder, L, which bears against a roller, M, on the support 0, and imparts to the support 0 and the chute a reciprocating movement, so that the firsteyelet in the channel will at the proper time be. presented to its position between the setting devices for the delivery of the eyelet, and then removed. A rotative movement is imparted to the hopper for the proper feeding of the eyelets;- but these devices, constituting no part of my invention, need not be herein further described.

P represents the work-table, which is made fast to a vertical slide, Q, arranged in guides R on the side of the frame, as shown, and so as to be moved freely up and down in said guides, and said guides are arranged to support said slide in a plane parallel with the axis of the setting mechanism. The table projecting from the slide stands in a plane between the setting devices and at right angles to their aXis, as

shown.

Attached to the lever O is a cam, T, which bears against the lower end of the slide Q. The work is placed over the table when in its down position, and when in that position the eyelet is presented over the follower 9. Then as the follower g-rises it enters the eyelet. The chute is withdrawn, leaving the eyelet on the follower. The table with the work thereon rises, causing the punch f to pass through the work and make a hole therein. eyelet through the material. The plunger G,

following, forces the eyelet against the fixed anvil F, upsetting the eyelet upon the work in the usual manner. Then the plunger G and its follower 9 drop. The work-table also drops by being released from the pressure of its cam T, all substantially as in the before-mentioned patent but it will be observed that instead of The follower then forces the IOC the vibratory movement of the table, whereby the plane of the table is constantly changing from one extreme position to the other, the table by my improvement is maintained in the same constant relative position to the axis of the setting mechanism from one extreme to the other-that is, its plane does not change,

but always stands at right angles to the axis of the setting devices, and because of its being thus vertically guided it is not liable to be de-- ranged, which is unavoidable in a vibrating lever.

What I claim as an improvement on the before-described machine in Letters Patent of I the United States No. 271,049 is- In an eyeletingmachine, the combination, with the fixed anvil F and its punch f, the

movable plunger G and its follower g, and
