EYELETlNG-MACHINE'.

SPECIFICATION forming part of Letters Patent No. 423,599, dated March 18, 1890. Application filed March 19, 1889. Serial No. 303,862. (No model.)

To all whom it may concern.-

Be it known that I, LOENDER O. EMERSON, of North Grafton, county of Worcester, State of Massachusetts, have invented an Improvement in Eyeleting-Wlachines, of which the following description, in connection with the ac-' companying drawings, is a specification, like and the eyelet-hole is made by apunch which descends on the material and co-operates with a movable die-block or anvil at the under side of the material.

In my improved machine the punch on its way into the material enters the eyelet held in usual manner at the end of av raceway or other equivalent support, the punch passing through the eyelet.

The punch described is made longer than, and is arranged inside of, a hollow set, both the punch and the set having co-operating means, whereby they may be actuated independently each of the other. In this manner after the punch has entered the eyelet and punched the material, the set, while the punch is yet in the eyelet, is moved to act upon the large end of the eyelet and drive it from the punch, while the, latter acts as a guide, into the hole previously made in the material by the said punch, the punch having in the meantime been partially raised, but preferably not far enough to lift it above the face of the material. The punch having been moved to punch a hole in the material, as described, the die-block or anvil referred to is quickly turned aside, and the set co-operating with the one surrounding the punch is quickly raised into the position occupied by the anvil when the punch entered the material, and

as herein provided for both sets are made to approach each other, and in so doing act to upset both ends of the eyelet. The punch is lifted from the eyelet just before the two sets act to upset the eyelet. 1

partially broken out.

let so that the punch might enter it on its way to punch the material.

. means to support or hold and presentthe eye- In my improved machine I have so constructed the eyelet-feeding mechanism that the eyelets are fed into the raceway consti-' tuting a support for them with their large ends uppermost, and to enable this to be done unerringly I have extended into the eyelet hopper one or more receiving branches, into which the eyelets can enter in only the right way, a brush or other usual sweep moving the eyelets along the said receiver or receivers into the raceway. The raceway has imparted to it a longitudinal movement away from thevpunch just after the punch in its descent through the eyelet has entered the material.

In other earlier machines the undermost set, madetubular, has contained a spring-pin, which,after the material has been acted upon by a punch to make a hole therein for the eye-:

let, has entered the eyelet at the end-of a raceway just before the raceway was moved longitudinally, and the said pin has been pushed back into the lowermost set against the spring supporting it by the end of the uppermost set.

Figure 1 in front elevation shows an eyelet-' ing-machine representing one form of my invention to be herein described, the downturned front end of the work-support being broken out. Fig. 2 is a sectional detail of the hopper and the upper end of the raceway and receiver; Fig. 3, a section-of Fig. 2 in the line 00. Fig. 4 is a detail showing three convergingreceivers leading to one raceway. Fig. 5 is a partial left-hand elevation of the machine shown in Fig. 1, the frame-work being Fig. 6 is a section of Fig. 5 in the dotted line as"; and Fig. 7 is a .detail looking upwardly from the dotted line 00 Fig. 1, chiefly to show an under side view of the-devices immediately below the said support, the ,arm g? and the link 12 being broken oif.

The frame-work A is and may be of suit-' able shape to'sustain the working parts.

The main shaft A, provided at one end with any usual form of driving-pulley, preferably some form of clutch-pulley under the control of a treadle, (not shown,) has on it two eccen tries a b, a cam c, and a crank-pind.

.The eccentric-strap b surrounding the cocentricb is represented as broadened and cut out at-its upper end (see 'Fig. 5) to receive a spiral or other spring b through which is extended a threaded rod 6 upon which, below the lowerend of the said spring, is applied a suitable nut, the upper end of the said rod being provided with an eye to embrace a suitable pin or stud b of an arm 12 fast on a rockshaft'b, the said rod entering loosely the upper end of the said eccentric-link. The rockshaft b has a second arm If, to which is connected a link I), it, at its lower end, engaging a stud b on the upright rod b of the carrier b Z2 to the forward end of which is secured by screw 19 the hollow or tubular upper set I). The spring b enables the set I? to yield 'to the thickness of the material.

The eccentrica is shown as surrounded by an eccentric-strap rod a, which at its upper end is connected to a stud a of an arm a fast on a rock-shaft a (shown only in Fig. 6,) the said shaft being parallel to the shaft b and having a second arm a to which is jointed a link a", the lower end of the link being connected to a stud a projected fromthe rod a having at its upper end an arm a to which is secured by a suitable set-screw, or in other usual manner, the punch 19, the'said punch being extended down through the hollow upper set b the two eccentrics being so placed on the shaft A as to move the said punch and upper set independently, the punch always remaining in the upper set, and, as herein represented, the lower reduced upper end of the punch is guided by the set. The rod a is reciprocated 'in the guide-stand as a. The crank-pin d is extended from a disk A con.- nected to or forming part of the main shaft A. The crank-pin (1 receives a link d, which at its lower end embraces a stud 01 shown as extended from a collar (i secured to the lowermost set d by a set-screw d, the said set d reciprocating in a post-like guide d secured rigidly to the frame-work. The upper end of the set d is reduced, as seen in Fig. 5, to leavea small point to enter and remain in the eyelet after the latter has been discharged from the punch by the set I), the said point acting as usual to prevent the eyelet from being crushed while being set.

The hopper B, preferably a circular shell,

having a feeder B is mounted on a carriage B having, as represented, a dovetailed foot 13*, which is free to slide in a similar-shaped guideway of a block 13", secured to or forming part of a stand B The hopper contains a wheel B (shown as a brush,) it being fast to a shaft B, extended through the-hopper and provided with a pinion B which is engaged by a toothed sector B pivoted on a stud B the said sector having connected to it a rod B which at its lower end is jointed to a stud or arm 13, fast to the rock-shaft a, (see Fig. 6,) the said rock-shaft, through the devices described, oscillating the said wheel in the hopper, so as to sweep'the eyelets 2 from the receivers f into the upper end of the groove of the raceway f the said raceway having at one side its central open groove a cover, as f to keep the eyelets large'end up in the said groove. This raceway is secured to or forms part of an arm of the carriage H, as best shown in Fig. 1. The raceway constituting a support for the eyelet to be entered by the punch and next to be set has at its lower end any usual form of detent, as 3, preferably some sort of a spring to keep the endmost ,eyelet of the row of eyelets in the raceway in place to be entered by the punch 19 as it descends to punch a hole in the material lying on the table 9, the said detent yielding,how-' i ever, readily to permit the removal of an eye'- let from the raceway or support after the same has been entered by the punch, the said raceway being at such time moved longi'tudinally' away from the punch by a rock-shaft e one arm e of which is connected loosely to a stud or projection'e'of the carriage E the said shaft having a second arm, as a one iend of which is normally held by a spring 5 in the range of movement of a stud 6 ex- ;tended from the arm b The spring5 is congnectedat one end to a stud of the carriage B -;and at its other end to a stud 6 of the guide I13 The rock-shaft e has its bearing in a block 6 at the upper end of i a stand e the said block, as shown, having sleeve-like exten- Isions at each side. The work-support g, supported rigidly on firocates the serrated feed-bar g and a small opening 7, in which stands and moves the.

anvil hwhen not in operative position. The isupport g has depending from it a guide 9 in which reciprocates the feed-carrying slide 5g, it having extended from it the arm 8, to which is secured the feed-bar 9 The arm 8 ,has connected to it loosely a link 12, jointed at its other end by a stud 13 to one arm of a rocker-lever g having astud g which takes 'a bearing in asleeve 20, herein shown as fixed to the support 9. The opposite arm of the said rocker-lever has jointed to it a link g, in turn jointed at its other end to a lever 14, pivoted at 15 to the frame-work.

The lever 14 is shown as grooved at itsinher side (see dotted lines) to receive a pin 16, extended from a regulating-block 17, ad-

Ice

0, having a second arm 0 provided with a roller-or other usual stud 0 which enters the groove of the cam c. The elbow-lever g in its movements reciprocates the slide g and actuates the feed-bar to move over the support g intermittingly the material in which the eyeletis to be set, adjustment of the block'17 providing different lengths of feed.

The slide g 'has at one side an extension, in

which is placed a presser-bar 23, having in it a vertical passage for the reception of the said presser-bar, the latterhaving an arm 24, the front of which is provided with a suitable resser-foot 25, to keep the material down on the feed-bar and the support 9, the said presserbeing acted upon bya suitable spring, as 26, (see Fig. 5,) which normally keeps the presser-foot pressed down.

The presser-foot, it will be understood, will move forward-in unison with the feed-bar;

but when the feed-bar is being moved backwardly the presser-foot is elevated from the material by, asherein shown, a lever m, pivoted at 29 onthebar 9 the said lever being connected by a rod 30 to a stud 31 of a lever m having its fulcrum at m and provided wit-h a roll 34, which in the rotation of the shaft A is struck by a cam 35, forming'part of the disk (I. The lower end of the rod 23 has a roller 28, which obviates friction between the bar and the lever m.

The support 9 has pivoted to it at 40 one end of the lever 42, which at or near its other end has attached to it the punch-block or anvil h, the said lever being slotted to receive a roller or otherstud 43 of an arm 44, ex-

tended from the slide 9, themovements of the said slide, when operating to effect the forward or feeding motion of the material,

acting through the stud 43 to vibrate the lever 42 and place the die-block or anvil in position immediately in the path of movement of the punch 19, the lower set 01 being then down, as in Fig. 5.

During the feeding movement of the material the punch p commences todescend, and in its descent enters the large upper end of the eyelet at the lower end of the racewayor support, the said punch continuing its descentand meeting the material just as the feeding-stroke is completed, the punch strik-,

ing the material immediately above the punch-block or anvil and making theusual hole for the eyelet. The hole having been made, the punch is raised slightly (in practice about one-sixteenth of an inch) to relieve the punch from the punch-block, and then the feed starts back quickly, the slide g in its backward movement (the foot being then by the upper set 11 it having been actuated and moved downwardly, but not until just after the raceway was pulled or moved backwardly far enough to retire from the eyelet then on the punch, the downward movement of the set I) after the removal of the eyelet from the raceway pushing the eyelet into the material.

The movements of the two sets I) and d are preferably such that after each comes in contact with opposite ends of the eyelet both of the said sets have sufficient movement one toward th'eother to upset the eyelet in usual manner, the 'punchretiring. from the eyelet just before the latter is fully upset. v. 4 n

It will be noticed that the receivers extend into and partially surround the brushB The grooves in the receivers (see Fig. 3).are narrower at their lower than at their upper parts, so that the eyelets can enter therein only with their small ends down, the brush in its movement in the direction of the arrow, Fig. 2, acting to sweep the eyelets lodged in the said receivers into the raceway, down which they slide. The brush in its backward movement brushes from the tops of the receivers any loose eyelets therein and not properly entering the grooves of the receivers.

I I do not desire to limit my invention to the exactform of hopper or brush, nor to the exact form of feeding mechanism; but instead may use any other well-known equivalent devices.

I claim W 1. In an eyeleting-machine, the combination, with a support for the eyelet ,to be set,

of a tubular set, means to reciprocate it, the punch extended therethrough, and means tov positively actuate it independently of the said set, and a punch-block or anvil, the combination being and operating substantially as described.
