DIVISION No. l.

T0 all whom it may concern:

Be it known that we,TIMoTI-IY K.REED and CrIAnLEs E. HOWARD, of West Bridgewater, county of Plymouth,State of Massachusetts, are the sole owners of a patent granted to T. K. REED and H. F. PACKARD, July 22, 1562, for Improvements in Eyelet-Machines; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side view of the machine. Fig. 2 is a front view of the same, with the station ary arm that carries the closing punch in section. Fig. 3 is a vertical section of thefeeding apparatus parallel with Fig. l.

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

This machine is composed of a stationary hopper in which the eyelets are put, and from which they are swept by an oscillating brush into holes provided for their reception in an interniittently-rotatin g cylinder, by which they are delivered into a chute, which deposits them, one by one, on an upright pin working through an upright reciprocating bolster, by which, after the perforations made iu the cloth or other material for their reception have been placed over them, they are brought into con'- tact with a punch and riveted or clinched, the several parts being operated by a lever, treadle, or other suitable mechanical means, by which they are severally put into action.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

A is a horizontal table supported by a suitable stand, B, and having erected upon it two standards, C C, on the top of which is the hopper D, having iiat parallel sides and a semicircular or inverted arc-formed bottom. 1n the sides ot' the hopper are bearings for the shaft a of the oscillating brush E, which its snugly between the said sides, and in the bottom of which there 'is an opening, through the interior of which works the upper part of the intermittently-rotating cylinder F, the horizontal shaft b of which works in bearings vprovided below the hopper in the standards C C. The cylinder F is hollow, and has provided init a single row of holes, c c, arranged at equal distances apart all round, the said holes being countersunk for the reception of the flanges of the eyelets, and otherwise of such size and form that the eyelets willt them loosely with their flanges outward, as shown in Fig. 3, in which the eyelets are indicated in red color. The opening in the hopper through which the cylinder F works is elongated behind the cylinders, as shown at d in Fig. 3, and tted with a stationary brush, Gr, the points of the bristles of which touch the periphery of the cylinder, the object of such brush being to assist the oscillating brush in brushing the eyelets into the holes cc of the cylinder with the Iianges upward. Within the cylinder there is arranged a stationary cam, H, secured to one of the standards C C, for the purpose of pushing out the eyelets fromthe holes as they are carried by the revolution of the cylinder below the axis thereof, and delivering them, with the flange downward, upon the inclined chute In At the back of the cylinder F and above the chute I there is fitted to the periphery of the cylinder) stationary curb, J ,from the upper end of which there descends in a backward direction an inclined plane, K, down which any of the eyelets that may not have been properly placed in the holes c c will be discharged from the cylinder.

The chute I is attached at its upper end to a stationary cross-piece, C', arranged between the standards C C by means of apin, f, upon which it oscillates laterally. This chute has its sidesformed for the reception of theilanges of the eyelets to retain them with the iianges downward as they slide freelydow'n it by gravitation, and the lower portion of said chute is horizontal and fitted with an elastic mouthpiece, g, to prevent the too free delivery of the eyelets onto the pin h, which is iitted to work up and down in a central bore in the upright bolster L. The lower horizontal portion of the chute I is open at the bottom for the entrance of the pin h, and in the side which is toward the spectator in Fig. 1

for the delivery of the eyelets. The bolster L is fitted to have a vertical reciprocating movement in fixed guides i t', attached to the support B of the machine, such movement being produced by its connection with a verti-y cally-operating lever, M, working on a fixed fulcrum, j, which attaches it to the support B. The pin h, which is of a size to fit the interior of the eyelets, has applied to it within the bolster L a spring, 7c, which tends to force it upward so that its point will protrude some distance through the top of the bolster'.

N is the stationary arm, which carries the upright fixed punch l, the point of which is of a size to enter the eyelets, and which has a concave shoulder ot' a form to turn over the upper edges of the eyelet and rivet it in the cloth or other material.

Toproducetheintermittently-rotatingmovement of the cylinder F to deliver the eyelets into the chute I the said cylinderis furnished at one end with a number of ratchet-teeth, m m, corresponding with the number of holes c c in the cylinder F, and its shaft b is itted with a loose arm, N', which carries a springpawl, n, and the said arm is connected by a rod, P, with the lever M. The downward movement of the lever produces a corresponding movement of the arm N', which causes the pawl to move over one of the teeth m m and the upward movement of the lever produces acorresponding movement of the arm N', and causes the pawl to engage with a tooth, m, and turn the cylinder a suitable distance in the direction of the` arrow, shown near it in Fig. 3, to deliver a new eyelet into the chute. The connection of the arm N' by a rod, Q, with an arm, R, on the shaft a of the brush E serves to produce the required oscillating movement of the said brush, whose points work in contact with the cylinder F.

The lateral movement of the chute I is produced by the action of a wedge-like projection, P', on the inner side ofthe rod P and a spring Q: elastic rod, S, oneend of which is connected with the said chute and the other end secured to the bottom of the table A, the said spring S exerting a constant tendency to press the chute toward the rod P and bring the mouth ot' the chute over the table A. Attached to the bottom of the table A there is an elbowshaped spring, T, the upper part of which vis so constructed and formed that it prevents the action of the spring S to bring the mouth of the chute over the bolster until the lever M has nearly completed its downward movement, when the said lever comes into action on a hook t, at the bottom of said spring and presses down this spring in such a manner as to liberate the spring S, and thus permit it to throw the chute suddenly to a position over the bolster L.

The construction and individual operations of the several parts of the machine having now been described, we will proceed to describe very brieily their combined operations to effect the eyeleting process. The operator stands infront ofthe machine holding` the goods ready perforated for the reception ofthe eyelets and operating the lever M. The operations of the brushes E and G, assisted by the rotary motion of the cylinder F itself, cause the holes c c in the said cylinder to receive the eyelets with their ilanges outward and as the cylinder rotates and brings the eyelets between the cam H and the upper part ofthe chute I the eyelets are discharged one by one upon the chute, down which they slide by gravitation. The jerk which is given to the chute I by the lib eration of the spring S when the lever M descends on the hook t of the spring T causes the eyelet which hasbeen near the mouth ot kthe chute, to force aside the spring mouthpiece g and arrive over the mouth, and as the bolster L rises with the lever M the pin h is caused to pass upward with the said bolster, through the said eyelet, and through the perforation in the goods, which is then placed by the operator over the said pin and the eyelet, and the continued ascent ot' the bolster causes it to lift up the eyelet and the goods as the chute lis moved aside by the action of the wedge P' and to place the eyelet on the punch l. The further a'scent of the pin la is prevented after its point comes in contact with the punch, and as the bolster completes its ascent it drives the upper edge of the eyelet against the shoulder 4 of the punch, and thereby causes it to be turned outward all round the punch, and rivets the eyelet into the goods. As the bolster descends again the pin h is forced upward relatively to it by the spring k, and when the movement has ceased and the said pin has descended with the bolster the eyelet and the goods are removed from the punch. f-

What we claim as our invention, and desire to secure by Letters Patent, is'- l. The combination of the hopper D, the rotating cylinder F, the cam H, and the chute I, substantially as and for the purposes described.

2. The oscillating brush E, applied and operating in combination with the hopper D and cylinder F, substantially as and for the purposes set forth. i

3. The stationary brush G, applied and operating in combination with the hopper D and cylinder F, substantially as and for the purposes described.

4. The curb J and inclined plane K, applied and operating in combination with the cylinder F and chute I, substantially as and for the purposes herein specified.

5. The reciprocating bolster L, pin h, and fixed punch l, in combination with the chute I, the whole arranged and operating substantially as and for the purposes set forth.`
