EYELETING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 272,382, dated February 13, 1883.

A Application tiled October 3l, 1881. (No model.)

To all whom 'it may concern Be it known that I, LoRENzo D. HAWKrNs, of Stoneham, in the county of Middlesex and State of Massachusetts, have' invented certain Improvements in Eyeleting-lllachines, of which the following is a specification.

This invention relates to the common form of eyeleting-machine, which performs the several operations of punching the eyelet-holes, inserting and upsetting in each eyelet-liole an eyelet, and feeding the work aftereach eyelet is inserted and upset; and its special novelty consists 'in the devices for impartingthclateral. and feed motions to the anvil, the same being constructed substantially as will be hereinafter fully described, and pointed out in the claims at the end ot' this specification.

For the purpose ot' enabling my improvements to be fully understood, I will brieiiy describe the construction and operation of a machine embodying the same. g

Referring to the drawings, Figure l represents a side elevation of such a machine. Figs. la and 1b represent detail views; Fig. 1C, a seotional view taken on the lineyy, Fig. 1. Fig. l1 represents a section on line z z, Fig. 2 Fig. 2, an elevation ofthe opposite side of the machine; Fig. 3, a top view; and Fig. 4, a section on line x w, Fig. l.

a represents the main fraine ofthe machine. b is the driving-shaft. ing punch, secured -to a lever, c', pivoted at c2 to an arm, c3, which is rigidly attached to a head, d, and is extended forward so as to support at its forward end the bed c4 of the punch. e is the upper set or anvil having the feedingfinger e3, and secured to a lever, e', which is pivoted at c2 to ears formed on the head d..

The levers c' and e' a-re capable' of oscillationl vertically on their pivots, and the head d is capable of rotating horizontally in a socket,

d', in the frame, so that the punch and anvil can oscillate horizontally in unison. rllhe vertical movements of 'the punch are effected by a suitable groovedoam,f, which raises and lowers a vertical rod, f', forked at its upper end, and having between the ends of its bifurcations a cross-bar, f2, which passes through a slotin the lever c.' The vertical movements of the anvil are eifected by a suitable cam, gp which raises and lowers a vertical rod, g', havc is the .work-perforating in its upper end a slot, g2, receiving the rear end of the anvil-lever e and permitting said lever to oscillate horizontally. The combined means foreft'ecting the horizontal reciprocating movements ofthe anvil and punch in unison, and which I regard as novel and original with me, consist ot' a lever, 71 pivoted to ears h on the frame a, and adapted to be oscillated laterally by means ot' a grooved cam, h4, and having two arms, h2 h3, at its upper end, one of which, h?, bears against the rear end of lever e', while the other, h3,- is connected to said. lever by means of a spring, h5. When the rocking lever h is oscillated inward by the cam h4, its arm h2 pushes the anvil-lever c inward by direct contact with it; but when said rocking lever is moved outward its arm h3 pulls outward the said anvil-lever through the spring h5.

-In machines of this class as heretofore arranged the spring has been supported at its outer end by an arm rigidly attached to the fratrie of the machine, so that when the anvillever was pushed against the force ot the spring the latter would be extended, and its increased resistance had to be overcome by the operating-lever; but in the present machine, as l now construct it, the entire spring moves with the lever h, and the latter, not having to overcome the resistance of the spring, is more easily operated.

` The length of the oscillations of the lever e in the slot gzris regulated by an adjustingscrew, hi, projecting into one end of said slot g2, and forming a stop for the lever, as will be readily understood. When the feed-adjusting screw h" is moved inward to make the outward movement of the anvil-lever c less than that of the operating-lever h, the spring will be slightly extended when the anvil-lever is arrested by the screw; but not such a' material variation of tension will take place as will impede the operation ofthe machine.

The other parts of the machine to be described, but which I do not claim herein, consist of an eyelet box or receiver, i, mounted on a standard, i', attached to a slide, i2, adapted to move between guides t3 i3 longitudinally of the frame a. The standard i supports the inclined roadway i4, through which the eyelets pass to the eyelet lifter and upse-tter. The

IOO

standard t" is reciprocated to alternately move the end of the roadway over and away from the lifter It by means of a cam, i5, and a lever, t, engaged with said cam, and pivoted at i7 to the frame a and at i8 to the standard i. The lever is is extended beyond its pivotal connection with the standard t, and is connected at its upper ends by a rod, t, Witha crank, il, which operates the agitator in the box fi. The lever 'i6 is oscillated by the cam i5, and therefore reciprocates the standard i and oscillates the agitator in the box t'.

j represen ts the bit'urcated presser-foot,which is mounted on a vertical rod,j', and is normally held down against the supporting-bed av by a spring, jz, and raised intermittingly against the pressure of the spring by a rockshaft,j3, having an arm,j4, on which the rod j bears, and an arm, j", adapted to be moved by 'a roller, j, projecting from the side of the cam f.

k represents the eyelet-lifter, which is normally held by a spring above the compressor It', as usual in machines of this class, the lifter being adapted to bear against the point ofthe feeding-finger c3 of the anvil, and yield when the compressor It rises to compress the eyelet. rllhe compressor is supported by a verticalrod, k2, whichis reciprocated vertically by an eccentric pin or block, k3, on a disk, 7a4, which rotates the driving-shaft, said pin or block working in a horizontal groove in the cross-head'kG on the rod k2. The c relet-box is provided with an agitator composed ot a thin metallic disk, m, rigidly attached to the crank-shaft i, and adapted to be oscillated thereby. The upper surface of the disk forms the bottom of the box, and is provided with a series of radial ribs, u, of any desired number, preferably four. These ribs are so arranged with relation to the ports 0, through which the eyelets pass from the box to the ruceway, that when the disk is oscillated the ribs will act to force or push the eyelets through said ports into the raceway.

The general operation of the machineissimilar to that of others of its class-that is to say, a piece of Work to be eyeleted is placed on the bed under the presser-foot; thepunch descends, perforates the work, and then rises; the punch and anvil are moved laterally in unison until the feedingnger is over the hole made by the punch, the anvil descends, and the finger enters the hole; the anvil and punch move laterally in the opposite direction until the feeding-finger ot' the anvil and the hole in the work are brought over the eyelet-lifter, (the punch remaining raised above the work;) the compressor and lifter are raised, taking an eyelet from the raceway and compressing it against the anvil, thus upsetting and securing the eyelet to the work. The raceway is moved for- Ward before the lifter rises, and backward alter it has taken the eye-let, as usual. The operation is repeated indefinitely, the punch descending after each eyelet is inserted and upset, and the presser rising to release the work while it is being fed and falling to clamp the work during the other partsof the operation.

I claim- 1. In an eyeletin g-tnachine,the combination, substantially as described, with the anvilcarrying lever e', of the positively-operating lever 7L and the spring h5, connected to and moving with the lever h, and also connected to the anvil carrying lever, whereby, when the lever his pushing the anvil-carrying lever7 it is not required to overcome the tension of the spring, as set forth.

2. In the herein-described eyeleting-machine, the combination of the pivoted operating-lever h, having the arms h2 h, the cam h4, for operating said lever, the anvil-carrying lever e', and the spring h5, connected to and moving with the arm h3, and also connected to the anvil-carrying arm, substantially as described.

In testimony whereofI have signed my name to this specitication, in the presence ot' two subscribing witnesses, this 5th day ot' October, A. D. 1881.
