BUTTON MACHINERY.

Specicaton of Letters Patent N o. 5,079, dated April 24, 1847.

To all whom, t may concern Be itvknown that I, LUCIENk E. Hicks, of Middletown, in the county of Middlesex and State kof Connecticut, have invented a new and useful Machine for Making Metallic-Plate Buttons; and I `do hereby declare that the following is a full and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of Vthis specification, of which- Y Figure l is a front elevation; Fig. 2 a section showing a diierent position of the revolving circles; Fig. 3 is a vertical view or plan of the first, or impelling` circle; Fig. 4, a vertical view or plan of the second or carrying circle, and of the tubular axle on which it revolves; Fig. 5, a vertical view or plan of the feeding table; Figs. 6, 7, 8, 9, 10, l1, and 12, are representations of sections and partsv o-f the machine and of the button plates in the different stages of the process of manufacture, as hereinafter explained.

Upon a bed plate or stand A, A, are erected two posts B, yB, which are connected at the top by an arch C. Centrally between these posts is a vertical shaft, upon which is mounted a band-wheel D, by means of which motion is communicated to the machinery. Below the band-wheel are two revolving circles E, F, the first of which is attached to the shaft and revolves with it; but the other circle, F, is mounted on the head of a stationary hollow cylinder G, as

its axle, and depends on the circleE, for,l (This cylindrical..

its occasional motion. axle has three vertical slots in its sides, as shown in the drawings, but which are vof no important use). In front of these circles is a feeding table somewhat elevated above the stand, and the rear end of the table extends under lthe front edge of the circle F. This table is shown in Figf, in which H, I, represent the heads of two dies, which are firmly fixed upon the stand, and are so formed as to give to the b-utton plates their required form when pressed upon the dies. y

J, K, L, are three branches of a horizontal slide, by which the metallic disks, or circular plates of which the buttons are made, and carried to their respective dies; the circular apertures J and L, are made to receive the disks for that purpose, and on the center branch K, is an oblique hub or projection, by means of which the slide is occasionally drawn back as ,hereinafter described; but it is quickly returned to its ordinary position by means of a helical spring, placed under, and parallel to the center branch.

Three punches a, b, c, Fig. 4, are vertically adjusted in the circle F, and are occasionally depressed and :made to descend in their sockets a sho-rt distance, but are returnedto their positions by springs. Four legsd, ve, j", Fig. t and g, Fig. 3,- project c downward from the circles, and Vto the 'bottom of each is attached, aj shoe (or wiper,v

represented in Figs. 6,7, 8 and 9,),forpurposes hereinafter described. Three vertical depressible pins 71 c', j, Fig. 4, are so adjusted in the circleF, thatthey may be occasionally depressed a quarter of an inch, but are returned to their ordinarypositions by springs, which are attached to the under side of the circles.

A stop or catch M, Fig. 4, is attached to the top ofthe stationary cylinder, and is Y ordinarilyy pressed against the inside surf ace of thecircle F by a spring, and occasionally stops and holds the sameV by pro-` jecting into holes or'cavities made forthe purpose in the centerward surface thereof. This Astop is furnishedV with an oblique shoulder 7c, by means of which the stop is occasionally withdrawn from either Vof the i cavities by the circular movement 4ofthe pins or legs Z, m, n, Fig. 8, which project downward from the ci-rcle E; thus liberating the circle F, from its detention. A cam o, (shown also in Fig. l0) is attached to` the under side of the circle E, for` the purpose ofoccasionally depressing the punches.

The die H, is of solid steel, and thehead thereof is so formed as to conform to the undersi'deof the back plate of the button;

the die I, consists of a permanent post, I

which constitutes .the center of the die, and

a hollow 4movable' Cylinder which iencircles the-epost, and which is supported in its ordinary' positionv byia spring, as shown seo'- f ti onally in Fig. 11, in which N, is the center post; 0, 0, the cylinder; @the spring which supports the cylinder, and g, the' foot of`a lifter, consisting of a wire, o-r small rod, by which the button is raised from the die when iinished; this lifter is ordinarily kept in its proper position by a small helical spring, coiled around the rod Vwithin the.

post; and on the`centerward side of the cylinder is ahorizontal notch or groove r," and the head of the die is so Vformed as to give the required form to the face-plate of the button, and contains four conical pins or points projecting upward, by which 'the' face-plate is pierced with eye-let holes.Y The bottom of the punch is so formed as to give the required shape to the outside of the back-plate of the button, and also contains four conical projecting Ypins which, when the punch descends, perforate the back-plate for eyelet holes. In the center of this punch is a vertical wire (Fig. 13) the top of which turns horizontally centerward, about half an inch; and this rod is connected to the punch and held in its ordinary position by a helical spring similar to that described in the die I. The bottom of the punch c, is made to conform to the inside of the face-plate of the button. The punch a, has a simple concave in the bottom, the rim of which serves to finish the button by gathering and setting down the rim or' edge of the face-plate upon that of the back plate. A small wire hook s, (shown in Fig. 12) is attached to the underside of the circle F, near the leg j, for the purpose of removing the button when inished.

Operation of the machina-The machine being putin motion by a belt passing over the band wheel, a disk of tin, or other metallic plate, is placed within each of the circular apertures J, L, of the feeding slide; the legs fw, w, w, take to the heads of the depressible pins L, z', j, whereby the circle, F, is put in motion, and the shoe, cl, takes to the hub or projection K, on the center branch of the slide, and-draws back the slide until the two disks fallvintothe cavities of the two dies; the slide then being liberated, is returned by the helical spring to its ordinary position. The punches 0, are then brought to positions directly over the two dies, H, I, the shoe e, at the same time, passing into the groove r, (Fig. 1v1) of the die I, (to prevent the depression of the cylinder,) when the stop, M, projects into the cavity t, which stops the circle F, and the three legs, w, rw, lw, depress and pass over'the pins 7L, z', j, Fig. 4, and the cam o, comes in cont-act with and depresses the punch a, without effect; it then approaches and depresses the punch b, whereby the disk plate in the die H, is stamped, molded and perforated, and by its adhesion to the perforating pins, is raised from the die. The punch c, is then depressed by the cam, whereby the face-plate, in the die I is molded and perforated. The stop M, is then withdrawn by the leg Z, andthe three impelling legs again taking to the three depressible pins, the circle F, moves on until the punch 5, vcomes to a position over the die I, whenthe stop projects into the cavity a, which detains the circle F, while the shoe g, passing on, comes in 'contact with the horizontal head of the vertical rod in the punch thereby depressing both the rod and punch until the perforating pins of the punch meet those of the die, thus preventing t-he further depression of the punch, while by the depression of the center rod of the punch, the plate is detached upon the face-plate in the die I.V The stop is again withdrawn by the leg 7n, andthe circle F, isa-gain vmoved on until the punch a, comes to a position over the die I, when the stop lagain detains the circle by projectinginto the cavity o; the legs again pass over the depressible pins, Vand the cam 0, overtakes and depresses the punch a, whereby the edge of the face-plate (which is somewhat larger than the back-plate) is drawn inward and closely pressed down upon the back-plate, thus completing the button. The stop is then withdrawn by the leg n and the circle moves on until the shoe f, takes to the horizontal foot of the lifter, (g, Fig. 11,) thus elevating the rod, and with it the button from the die I, when the button lis caught by the hook s, (Fig. 12) and deposited in a rev ceptacle.

I shall occasionally place short vertical tubes over the two apertures of the feeding slide, for the purpose of holding a quantity of the disks or circular plates, to supply the feeding slide, and avoid the careV of placing each disk within the apertures severally by hand.

'Ihe small sectionals y, a, at the bottom ofthe drawings, represent the two plates v after being stamped or molded, and a button composed of the two plates after bein locked together.

What I claim as my invention and desire to secure by Letters Patent, is-

The circles E and F, with their punches, pins, cam, legs and shoes; in combination with the dies and the feeding slide, in the manner and for the purposes herein described.
