EYELETING: MACH I N E,

SPECIFIGATION forming part 01 Letters Patent No. 476,504, dated June 7. 1892. Application filed September 14, 1891. Serial No. 405,621. (No model.)

To all whom it may concern.-

Be it known that I, ERASTUS WooDwARn,

of Somerville','in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Eyeleting-Machines, of which the following is a specification. A

, hi invention has for its object to provide a simp e machine for inserting and upsetting metal eyelets in holes previously prepared,

the machine being adapted to be operated by bodying my invention, showing the bottom set raised and the eyelet-chute moved back. Fig, 2 represents an clevationofthe opposite side of the same, showing the bottom set de-' pressed and the eyelet-chute moved forwarth Fig. 3 represents an elevation of the side op-' posite that shown in Fig. 2, the bottom set being depressed and the chute in its forward and lowest position. Fig; 4 represents an enlarged sectional view of a portion of the machine, the bottom set and chute being shown in the same relative positions shown in Fig. 3.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the frame of the machine, provided with an overhanging arm a, to which is affixed the usual top set which is formed, as usual in eyeleting-machines, to upset the end of the tube of the eyelet and form a flange corresponding to the flange originally formed on the eyelet.

1) represents thebottom set, which is aiiixed to a plunger 12', adapted to'slide vertically in a tubular guide a formed on the supporting frame, said plunger being reciprocated vertically by a connecting rod or pitman b pivoted at Z1 to its lower end, and an oscillating wheel or gear 0, to which the lower end of said pitman is pivoted at If. said gear a being mounted upon'a rock-shaft c, which is journaled in fixed hearings on the supporting-frame and is rocked or oscillated by the. means presently described; The bottom set is provided with the usual eyelet-picking finger (Z, which is yieldingly supported by a spring (lwithin the plunger Z) and normally projects above the bottom set far enough to enter the lower end of the inclined eyelet-- chute e and enterthe lowest eyelet therein, said finger disengaging the lowest eyelet from the chute when the bottom set is rising and holding the eyelet in place upon the bottom set while the latter rises and eo-opcrates with the top set in upsetting the eyelet in the manner common .to all' eyeleting-machines.

'lh eeyelemchute e is affixed to a slide 6',

which is movable on a pivoted guide f, hereinafter referred to, in the direction required to move the lower end of the chute horizontally toward and from' the finger (Z. The guide is pivoted .at to the supportingtrame and is provided with a groove or way -f having dovetail edges which receives a dovetail-ribon the inner side of the slide 2,

saidwaypermitting the slide and the chute thereon to move horizontally. The guide fis provided atone end with an arm f which is connected byarod f with one arm of a rocking bar or lever f", which is pivoted at f to the supporting-frame. The lever f is provided at its opposite ends with studs ortrundle-rolls f f, which are arranged to be operated, respectively, by cams g and (j, formed on a plate which is mounted-to rockloosely on the rock-shaft c.

, 7L represents a collar aftixed to the rockshaft c and provided with an arm h, which is arranged to alternately strike the cams g and g' and cause the same to oscillate the lever f in such manner as to first raise and then depress the arm of said lever, with which the connecting-rod f" is engaged.

2' represents. a segmental gear, which is mounted to oscillate on a stud i, affixed to the supporting-frame, and is engaged with a segmental gear 0, ailixed to the rock-shaft c.

2' represents an arm f armed on the segmental gear 1' and adapted to be connected with a rod (not shown) extendingdownwardly to a.

treadle arranged to be moved by the foot of the operator. 'lhegear t' is rocked or oscillated in a predetermined arc by movements of the treadle, the latter being depressed by the operators foot and raised by a suitable spring, each movement of the treadle imparting a corresponding movement to the segmental gear 2', which movement is imparted by said gear to the gear 0 and rock-shaft c, the arm 71., affixed to said rock-shaft, being therefore caused to oscillate through a corresponding arc. The oscillating movement of the arm 7L is such that at one extreme it strikes the trundle-roll f and thus raises the end of the lever f upon which said trundleroll is located,this movement being imparted through the rod f to the pivoted guide f, which is swung upwardly on its pivot f and thus caused to elevate the" lower end of the chutee. lVhen the arm 7L is carried to the other extreme of its movement-,it strikes the cam g, forces the latter upwardly against the trundle-roll f thus raising the other end of the lever f and depressing the end connected with the pivoted guide f, said guide being thus swung downwardly and depressingthe lower end of the chute.

'lhe eyelet-chute has, in addition to the vertical movements above described, horizontal movements, which are produced as follows: j represents an'arm or crank afiixed to the rock-shaft c and connected by a rod 7" with one arm of a bell-crank lever 7;,which is pivoted at is to the frame of the machine, and has its other arm connected by a rod k with the slide e, supporting the eyelet-ch ute. The described movements of the rock-shaft 0 cause the crank j and the connections between it and the slide e to reciprocate said slide in a substantially horizontal direction on the guide f.

The operation of the described mechanism is as follows: When the treadleis depressed by the operator, the arm h on the rock-shaft c is held against the cam g and the end of the lever f over said cam is raised by the latter, so that the lower end of the eyelet-chute occupies its highest position. The bottom set is at thesame time elevated and caused to co-operate with the top set in upsetting the last eyelet detached from the chute. lVhen the operator releases the treadle, the upward movementof the latter causes the depression of the bottom set, and at the same-time the forward movement of the chute, the latter being brought forward, so that its lower end is entered by the finger (Z on the bottom set, as shown in Fig. 2. \Vhen the chute and finger reach the position shown in Fig. 2, the arm It strikes the earn 9' and elevates the end of the levei'f, carrying the trundle-rollf, thus depressing the swinging end of the guidef, and with it the lower end of the eyelet-chute, the chute being thus brought down over the upper end of the finger (1,50 that said finger entors the lower eyelet in said chute. The operator then depresses the treadle, thus causing thebackward movement of the chute, and at the same time the downward movement of the bottom set, the eyelet being thus removed from the chute and carried upwardly by the bottom set and eventually upset by the combined action of the bottom and top sets.

It will be seen that the mechanism for giving the eyelet-chute its horizontal and verti cal movements is all comprised in the rockshaft 0, the arm 71., the segmental gear 0, and

the crank j on said rock-shaft, the cam-plate g, the rocking lever the pivoted guide ff, connected with said ever, and the segmental gear 1 adapted to be operated by a treadle. Said mechanism is extremely simple and durable, and gives the desired movements to the eyelet-chute and bottom set without liability of failure of said parts to properly cooperate.

I claim- 1. In an eyeleting-machine, the combination, with the fixed top set andthe reciproeating bottom set, of the eyeletchute, a slide affixed thereto, a guide supporting said slide and chute, said guide being pivoted to the supporting-frame and adapted to oscillate vertically, mechanism for reciprocatingthe slide to carry the chute horizontally toward and from the finger of the bottom set, and mechanism for oscillating the pivoted guide to raise and lower the chute, as set forth.
