IMPROVEMENT IN EYELETING-MACHINES. l

Specification forming part ot' Letters Patent No. L13,8 I 6, dated August 9, 1864.

To @ZZ whom it may concern.-

Beit known that I, TIMOTHY K. REED, ot' North Bridgewater, in the county of Plymouth and State ot' Massachusetts, have invented an Improved Eyeleting-lltachine; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sutiicient to enable those skilled in the art to practice it.

My improvements relate particularly to th at v class of machines for setting or clinching eyelets employing` a hopper or reservoir for conttining the eyelets and an inclined chute or roadway for conducting them from the hopper to the setting-tools. Y

The invention consists in the peculiar construction of the hopper with reference to the delivering` therefrom into the chute of the eyelets by the (3o-operation ot' a vibrating or rotating brush or brushes; also, in the manner o? operating the vibrating chute and the movable set with reference to each other, also, in the manner of operating the sliding-pin of the lower set.

Figure 1 ofthe drawings shows a side elevation of an eyeleting-maehine embodying my improvements. Fi g. 2 is a plan ofthe hopper with its top plate removed and the adjacent portion of the chute. Fig. 3 isa side view oi' the hopper, showing the eyeletpassages. Fig. 4 is a cross-section of the chute and the contiguous side 0f the hopper, taken through one of the eyelet-passages.

c denotes a base-plate having a standard, b, which supports a tixed upperset, c, in connection with which a movable set, d, works, said set d being attached to the top ot' a pis ton or shaft, e, which slides vertically in a pro jection from the standard b, as will be readily understood. A short link, f, connects the lower end of the pistou to one end ot' a rocking-lever, g, which actnates the setting mechanism and the vibrating chute. This lever is hung upon a fulcrumpin, h, extending from the standard b, and it has 'an arm, i, rising from it, said arm being` stationary with .respect to the lever and carrying on its upper end the hopper 7s and its chute l. Force applied to the outer end of the lever g carries the sets together and moves the chute away from the sets, whilea spring, in, carries the parts into their normal position, as seen in the drawings; and it will be readily understood that the motions of the lower set toward and away from the upper set, and the motions of the end of the chute away from and toward the sets, are simultaneous-tl1at is to say, as the set d begins to move upward the end n of thechute begins to retreat, and as the lower set in descending reaches its normal position the end of the chute simultaneously passes over the top thereof and the pin o receives the lower eyelet in the chute, this simultaneous coaction of parts being effected by actuating the chute and lower set or piston e directly from the lever g. The lower end of the chute is so disposed with relation to the pin o ofthe setd that the lower eyelet in the chute is entered by said pin while in the chute, so that the chute can fall back from the set at the same time the set begins to rise, and so that the eyelet is always in position or over the set before the set begins its upward movement. When, therefore, after setting` an eyelet the lower end of the chute is advancing to the position shown in Fig.l, the pin 0, upon which the eyelet rests, and which holds it in its as cent, is withdrawn from the set or below the top thereof, so that the eyelet i' (which is at the bottom of the chute resting against a stop, p) can pass over the center of the set, and as the chute reaches this position the pin flies up and passes within the eyelet. This is effected as follows: The pin o extends down through the set d and piston e, and is hung upon a lifter-bar, q, which is jointed to the lever g, and is kept in position by a spring', s. The bar q has an incline, t, and a depression, u, as seen in the drawings. A swinging rod, fu, is hung to the arm b, its lower end resting normally in the depression u. When, as the lower set rises, the point of the pin o strikes the point o' the upper set, the pin is stopped, while the set continues to ascend. This separates the front ends of the lever g and the bar q until the lower end of the rod v rises above the depression u and swings over and in rear ot' the incline t. As the lower set and pin o descend the upper end, w, of the rod o strikes a stop-screw, x, which causes the lower end to press against the incline and depress the bar q with -respect to the lever g, drawing the v lever reaches its lowest position the end of the chute is brought over the set and the end of the swinging lever is forced beyond the ineline, when the spring s draws up the bar q and the pin o enters the eyelet. The hopper 7c is stationary with respect to the chute. It contains a series of vibrating brushes, a', eX- tending from a rocking shaft, b. A crankarm, c', at the bottom of this shaft, is jointed by a rod, d', to the standard b, so that as the hopper is vibrated by the action of the lever g the brushes receive a partial rotary movement, which agitates the body of' eyelets within the hopper and lying against the brushes. The lower quarter 'of the hopper adjacent to the chute from at or near the upper. point where the chute joins to where it leaves the hopper is provided with a series of outlets or passages, c, (which may, however, be made as a continuous passage,) so formed as to admit of the passage of the eyelets through them into the adjacent portion of the chute, down which adjacent portion they slide into the main part of the chute. The movement of the brushes constantly carries the eyelets against the passages, into which they slip whenever they are in proper position with, respect to the passages, which are so formed as only to receive the eyelets when they are right side up.

Previous to my present invention it was customary with a machine of this kind to pass the eyelets from the bottom of the hopper into the chute, or from the hopper into a rotary cylinder, and thence into the chute, but in no case, to-my knowlelge, was a hopper so made as to convey the eyelets or allow them to slide over the side of the hopper into a sin glechute channel, so placed in juxtaposition with the hop` per as to deliver the eyelets directly into the chute from the hopper. By this method there is no danger of the eyelets clogging or becoming interlocked in their passage from the hopper to the chute or from the hopperi'to the settingtools. The position of the lower set and the end of the chute when the eyelet is being clinched is shown in Fig. l in dotted lines, and the position of the pin o when withdrawn from the lower set previous to entering the eyelet is denoted by the dotted lines in red.

In connection with an inclined chute and hopper, I claim- 1. Constructing the hopper with eyelet-passages leading from the side thereof when said passages are so arranged as to direct and convey the eyelets immediately into the chute, substantially as described.

2. Operating the vibrating chute and the lower set simultaneously by the lever g, or its equivalent, substantially as set forth.

3. Causing the pin o to withdraw during the descent of the .lower set and enter the lower eyelet in the chute as said eyelet comes over the set, substantially as set forth.

4. The combination of the lifter-bar q, spring s, and rod c, operatin g in the man ner described for eii'ecting the movements of the pin o.
