IMPROVEMENT' IN EYELET-MACHINES.

Specilication forming part of Letters Patent No. 35,952, dated July 22, 1862.

` To all whom t may concern.-

Beit known that we, T. K. REED, of East Bridgewater, in the county of Plymouth and State of Massachusetts, and H. F. PACKARD, of North Bridgewater, in the county and State aforesaid, have invented a new and useful Machine for Inserting and Securing Eyelets in Cloth, Leather, and other Materials; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the ac companyin g drawings, forming part of this specification, in which Figure l is a side view of the machine. Fig. 2 is afront view of the same with the stationary arm which carries the closingpunch in section. Fig. 3 is a vertical section of the feeding apparatus parallel with Fig. l.

Similar letters of kreference indicate corresponding partsin the several figures.

This machine is composed of a stationary hopper in which the eyelets are placed and from which they are swept by an oscillating brush into holesprovided for their reception in an intermittently-rotating cylinder, by which they are delivered to a laterally-oscillating inclined chute, which deposits them one by one on an upright pin working through an upright reciprocating bolster, by which, after the perforations provided in the cloth or other material for their reception have been placed over them, they 'are brought into contact with a stationary punch and riveted, the several part-s being operated by a lever, treadle, or other suit-able mechanical means by which they are severally put in motion.

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 O, on the top of whichv is the f hopper D, having fiat parallel sides and a seinicircular or inverted arc-formed bottom. In the sides of the hopper are bearings for the shaft a of the oscillating brush E, which iits 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?) of which works in bearings provided below the hopper in the standards C O. This cylinder is hollow and has provided in it a single row of holes c c, arranged at equal distances apart all around, the said holes being countersunk for the recept-ion of the flanges of the eyelets, and otherwise of such size and form that the eyelets will nt them loosely, with their flanges o utward, as shown in Fig. 3, in which the eyelets are shown in red color. The opening in the hopper through which the cylinderF works is elongated behind the cylinders, as shown at d in Fig. 3, and fitted with a stationary brush G, the points of whose bristles touch the periphery ofthe cylinder, the object of such brush being to assist the oscillating brush in brushing the eyelets into the holes c o of the cylinder with the flanges upward. lVithin the cylinder there is arranged a stationary cam H, secured to one of the standards O C, for the purpose of pushing out the eyelets from the 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 l. At the back of the cylinder and above the chute I there is fitted to the periphery of the cylinder a 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 l is attached (at its upper end to a stationary cross-piece C', arranged between the standards C O by means of a pin f, upon which it oscillates laterally. This chut-e has its sides formed for the reception of the iianges of the eyelets to ret-ain them with the flanges downward as they slide freely of the said chute is horizontal and fitted with an elastic mouth-piece g to prevent the too free delivery of the eyelets onto the pin h, which is fitted 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?) t, attached down it by gravitation, and the lower portion to the support B of the machine, such movement being produced by its connection with a vertically-operatin g lever M, working on a fixed fulcrumj, which attaches it to the support B. The pin 71, which is of a size to lit the interiors 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. t

N is the stationary arm which carr1es the upright ixed punch l, the point of which 1s of a size to enter the eyelets, and which has a concave shoulder of a form to turn over the upper edges of the eyelet and rivet it in the cloth or other mate-rial.

To produce the intermittently rotating movement of the cylinder F to deliver the eyelets into the chute I, the said cylinder is 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 Z) is itted with a loose arm N, which carries a spring-pawl 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 a corresponding movement of the arm N and causes the pawl to engage with a tooth in and turn the cylinder a suitable distance 1n the direction of the arrow (shown near it in Fig. 3) to deliver a new eyelet into the chute. The connection of t-he 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 of the rod P and a spring or elastic rod S, one end of which is connected with the said chute and the other end secured to the bottom of the table A, the said spring S eX- erting av constant tendency to press the chute toward the rod P and bring the mouth of the chute over the bolster L. Attached to the bottom of the table A there is an elbow-sh aped spring T, the upper part of which is so constructed and formed that it prevents the action of the spring S to bring t-he mouth of the chute over the bolster until the lever M has nearly completed its downward movement, when the vsaid lever comes into action on a hook t at the bottom of said spring and presses down the said spring in such a manner as to liberate the spring S, and so permit it to throw the chute suddenly to a position over the bolster L.

The construction and individual operations of the'l several parts of the machine having now been described, we will proceed in conclusion to describe very briey their combined operations to effect the eyeleting process. rlhe operator stands in front of the machine, holding the goods ready perforated for the reception of the 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 flanges outward, and as the cylinder rotates and brings the eyelets between the cam. H and the upper part of the chute l 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 liberation of the spring S when the lever M descends onto the hook t of the spring-T causes the eyelet which has been near the mouth of the chute to force aside the spring mouth-piece g and arrive over the mouth, and as the bolster L rises with the lever ill the pinh 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 of the bolster causes it to lift up the eyelet and the goods as t-he chute is moved aside by the action of the wedge P and to place the eyelet on the punch Z. The further descent of the pin h 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 around the punch and rivet the eyelet into the goods. As the bolster descends again, the pin 7L is forced upward relatively to it by the spring 7c, and when this movement has ceased and the said pin has descended with the bolster the eyelet and the goods are removed from the punch.

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 l, substantially as and for the purpose herein specied.

2. The oscillating brush E, applied and operating, in combination with the hopper D and cylinder F, substantially as and for the purpose herein described.

3. The stationary brush Gr, applied and operating, in combination with the hopper D and cylinder F, substantially as and for the purpose herein set forth.

4. The curb .l and inclined plane K, applied and operatin g, in combination with the cylinder F and chute I, substantially as and for the purpose herein specified.

5. The combination of the laterally-oscillating chute I, the reciprocating bolster L, pin h, and lixed punch Z, the whole arranged and operating substantially as and for the purpose herein set forth.
