JEREMIAH KEITH, OF NEW BEDFOR-D, MASSACHUSETTS.

Specification forming part of Letters Patent No. 37,170, dated December 16, 1862.

To all whom it may concern:

Be it known that. I, JEREMIAH KEITH, a citizen of the United States of America, and a residentof New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful or Improved Machine for Punching and Eyeleting Shoes or other Articles; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figures 1 and 2 are side elevations of the machine, showing in red lines atreadle applied thereto. Fig. 3 is a top view of the said machine with the cover of the eyelet magazine case turned backward. Fig. 4 is a transverse and vertical section taken through the eyeletmagazine, and so as to show its operative mechanism. Fig. 5 is a vertical and longitudinal section taken through't-he punching and upsetting mechanism. Fig. 6 is a front view of the said machine.

' The object of my invention is to produce a .machine whichshall not only punch or make the holes for the eyelets which are to be inserted in a shoe or other article, but introduce and properly fasten the eyelets in such shoe or article.

In the drawings, A denotes the frame or table for supporting the. operative parts of the machine. 0n the rear part of the said table,

and extending upward therefrom, is-a rectt angular box or case, B, which is provided with a cover, a, and has disposed within it a hopper or eyelet magazine, 0, which may be of a rectangular or any other convenient shape, and be furnished with a lid or cover, a, the said magazine being supported on an inclined platform or partition, b. Thesaid platform is so pivoted to the sides of the box as to allow it (the said platform) to have a vertical tilting movement, which,of course,is imparted to the magazine 0. The said magazine has a stud or tooth projecting downward from its lower surface and extending through a rectangular slotmade longitudinally through the The said stud or tooth engages with or is operated by a sectoral gear, b, or semicircular plate, having teeth 0 0 arranged upon its outer surface. The said gear is supported by a pivot, e, which passes through it and into a vertical plate, d, as seen in Fig. 4. To one end of such gear a connec ing-rod,f, is attached and extends downward, and is connected to a treadle or any other motor which may be employed to give'a vertical motion to the punching and upsetting mechanisms, vertical or upward and downward movements of the rod f impart to the hopper reciprocating intermittent movements, whereby the mass of eyelets are caused to arrange themselves with their broader parts or flanges downward. The said magazine is provided with a series of discharge-passages, g g, the same being arranged at its lower front side and opening into the upper end of the inclined chute D, as shown in Fig. 5.

Fig. 7 is an inner side view of the front part of the hopper, showing the discharging-passages. These passages have their greatest width at their lower parts, and are to be of a size just suflicient to allow the eyelets to pass easily through them, when such eyelets are brought into their proper positions, the object of so making the said passages being to cause apositive arrangement of the eyelets-viz., with their flanges downwardbefore entering the chute D. The conductor or chute D is attached to the platform b, and consists of an' inclined tapering box, whose internal height should be slightly greater than that of the eyelets. which are to pass through the same, but not great enough to permit the eyelets to turn during their descent through the chute. The lower part or discharging end of the said chute I form forked,in order that the lowermost eyelet mav have its lower end so exposed as to be readily entered and carried forward by the seizer and carrier u,t0 be hereinafter described.

E is what I term the retainer, the same being attached to'a standard, G, and consists of a thin fiexile spring, h, or its equivalent, so arranged as to extend down and retain the lower eyelet in a proper position to be seized by the carrier before mentioned. This spring should be of such a yielding nature as to easily give away and readily allow the seizer to take the lowermost eyelet and carry it forward out of the chute or conductor.

H is a vertical slide-bar, which extends down through the table A, and has its lower end connected with a cross-bar, 0 which is 'to be attached to a treadle or any other motor suitable for imparting vertical movements to it. To the upper end of the said bar a bifurto be hereinafter described. The

were... I, is jointed, and extends atright angles therefrom, and has a block, K, which carries a punch, L, on one of its ends, while its opposite end is provided with what I term 'end.; The said pin, when-brought downward,

enters the eye of the eyelet,while the flat surface or shoulder Z compresses the eyeletupon its top surface. The'said block Kis mounted upon a shaft, m, which extends horizontally through theforks of the bar Land carries on one of itsends a notched wheel, M, which operates in conjunction with a spring catch or pawl, n, arranged on the side of the bar I, as seen in Fig. 1. .The said pawl is thrown .out of its'notches by means'of a catch-lever or tripper, o, acting .upon the, rear partof said pawl, the whole being formed and arranged asshown in said figure. The other end of the shaft m'car'ries a friction-wheel, N,'which operates with a spring presser-bar, O, to give the proper rotary motion to the upsetter and punch L. This presser-bar consists of a rigid lever, having'a piece of india-rubber or other mate.-

rial suitable to produce friction applied to its .outer face. Said bar is attached to two hori z'ontal slide-ba s, p p, which extend horizontally through slots formed through a rectangular frame, 1?, which is constructed and arranged as shown in the drawings, Figs. 1 and 2. Each of the said bars p'is encompassed by a helical spring, q, one end of which is connected to the inner face of the frame P, while the-other end is atfixed to the said bar, the

object of such spring being to force the presses bar 0 out of action with the friction-wheel N. Furthermore, in orde'rto maintain the presserbar and the friction-wheel N in contact at the proper periods for imparting to the block K, which carries the punch and upsetter, its semirevolutions and intervals. of rest, a jointed lever or toggle-joint, Q, isdisposed within the frame 1?, and has its two ends passed through slots in ade horizon tally through the said frame, as shown inFig. 2. The frontend of the said lever projects, when forced outward, through the frame P, and forces the said press'er-har 0 into engagement with the wheeLN. :Thev

devices for operating the said lever Q are two studs, 1" 1", arranged upon a vertical bar, s, at

tachedl'o thebar I, before mentioned, so that when the latter isdraw'n downward the upper stud, r, is brought in contact with the toggle, so as to bring the parts of the latter into a straight line, and thereby force the. presserbar against the wheel N and cause the latter to make a semi-revolution. When this is effected, the spring 1? causes the slide-bar H to be elevated and the lower stud, r, to strike against the under side of the toggle and raise the same, and thereby throw it out of action upon the presser-bar, which, by means of the springs q q, is drawn away from the wheel N, and remains out of contact with the latter until the toggle is again forced downward.

P is a coiled spring, which has one of its ends attached to the cross-bar Q while its.

other end is connected to the table A, as seen in Figs. 1 and 2, its object being. to elevate the slide-rodH and the-connecting-rod f, after each depression thereof.

R represents the frame for supporting the rotator S, which carries ondoneof it's ends a punching block-or bed, t, and on its other'end an eyelet -separator and carrier, u, and the mechanism by-which it is operated. The-said punching-block is of a cylindrical orother convenient form, having a'flattopsnrface, and

serves to support th'eshoe while having its eyelet-holes punched; The said eyeletrse'parator may be of a similar form, but should have a pin or stud, u, extending from its end, such pin resting on a spring, a, which allows the pin to be forced into the main partduring the depression of the upsetter while fastening the'eyelet in theshoe.

T is the shaft of the rotator, which extends through the sides of the frame R,an d has its journals resting in suitable bearings formed therein. One end of the said shaft carries a spur-wheel; U, which engages with a pinion, V, arranged'on one side of the frame It, as shown in Fig. 2. 'The said pinion is supported and so as to be capable of being revolved upon a pivot, 41, which passes through one side of the frame R W isa lever, which is arranged on the sai'df pin v and turns on the same as afulcrum. On one end of the said lever a spring-pawl, u, is

disposed, the same, operating withthe pinion V, as shown in thedrawings, the other end of said lever being join ted to a connecting-rod, X, .whose other endis jointed, to an arm, Y, extending from the slide rod H. On the opposite end. of the shaft T a notched wheel, Z,

is arranged, and operates with a spring-pawl, x. Thesaid pawl is thrown out of engage inent with the wheel by means of a trippinglever, A, which is jointed tothezbar 0 The said lever is constructed with a shoulder near its upper end, which operates with another shoulder madein the rear end of the longer arm of the pawl a: to throw the pawl outof en'- gagementwith the wheel Z, and allow the latter to be rotatedone hundred andeighty degrees. .The lever Aiis maintained in proper positionv with respect to the pawl by'meansof the spring 3;, the whole being formed'and disposed as shown in Fig. 1.

Havingdescribed the construction of my ,machine, I will'now describe its operation:

If we suppose the slide-bar H and the connect-- in g-rod f (which is attached to the mechanism for actuating 'the magazine 0-) to be connected to a foot-treadle disposed below them, the up-* ward and downward movementsof the treadle,

acting through the connecting-rod and the I sectoralgear bi, will give to the eyelet-magazine longitudinal reciprocating intermittent movements, which, acting in conjunction with the force of gravity, serves to bring the eyelets into proper positions for passing into the conductor D, the passing of the eyelets into the .hole.

guide or conductor being caused-by the verti 'cal tilting movements imparted to the chute by 'thesudden. elevating action of the eyelet seizer and carrier while removing an eyeletfrom the retainer. If now.we.sup'po se a sufficient number to have. been introduced into the. "chute or conductor, and we also suppose the punch to stand with its cutting-edge downward directly over the punch-block, and if we also suppose a shoe or other article to be punched "to-be placed upon the block, if, under these circumstances, the punch is depressed upon the punch-block, an eyelet-hole will be made in; the leather of the'shoe. N ext, the s'pring 1 will elevate the slide barH andbring it back to its first. pfosition,causing,-in the meantime," .both the punch and punch-block to-- be re:

volved one hundred and eighty degrees, and

g the upsetter andeyelet-carrier to be respectively brought into the position just occupiedby the punch and punch-bed.- During.lsuch rotation the eyelet carrier and separatorpasses into the eye of the lowermost eyelet in the conductor, forcessuch eyelet out from ,the springretainer, and carries it forward into the hole previously made by the punch. lf next, we

again depress the treadle, the upsetterwill be brought down toward and upon the eyelet-car-r 'rier and its eyelet.

The stud u. of the eyeletcarrierbeing forced into its chamber, such eye! let will be compressed between the flat surcrate asset-forth;-

or article to be operated upon will have its eyeletholes punched and the'eyelets .properly inserted and secured therein. 7

It will behevidentthat if the eyelet-holes were made in the shoe prior to beingoperated on by themachine the punch and punching bed might be dispensed with.- 'In this case all weshould have to 'do would be to put another eyelet-carrier in the place of the punch bed and withdrawthe stud ,1, (which forces the tog gle-lever against the Presser-ban) and thesaid' presser bar would have no action on. the friction-wheel N, and consequently therewill "beno revolution of'the upsetter,but it will be free to have vertical. movements imparted to it as before, and will. operate with the eyelet separators and carriers,as before described..-
