TO ALL WHOM Il MAY CONCERN: e p

Be it known `that I, JACOB WILD, (assignor to J. S. Mason & Co.,) of Philadelphia, Pennsylvania, have invented a Machine for Making Metal Boxes; and I do hereby declare the following to `be a full, clear, and lexact description of the same.

My invention consists of certain mechanism, fully described hereafter', by which thc bottoms and sides' of blacking and other'metal boxes may be rapidly and firmly secured together, and have the desired shape impartedl to them.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe Vits construction and operation, reference being had to the accompanying drawing, which forms a part of this' specification, and in which- Figure 1 is a side elevation of my machine for making metal boxes. Figures 2 and' 3, sectional elevations, showingV the parts in different positions.v Figure 4, a sectional elevation on the line 1 2, iig. 1. Figure 5 an end elevation. Figure 6 a plan view; :ind l Figures 7 and 8, enlarged views of parts of themachine, showing the s aid parts in different positions.- The fralne of the machine consists of' standards a a al a2, top plate B, and cross-pieces Z211', and in. bearings near the lower ends of the standards a a2 turns a' horizontal shaft, C, on which aretwo cams, d d', and a driving-` pulley, c. On a guide,e, secured to the inner side of' the standard a1,iig. 2, slides a frame, D, in which turns a vertical shaft, E, a pinicn,f, at lthe lower end'of this shaft, gearing into a cog-whcel,g, turning, `en a `pin secured to a bracket on the cross-piece b. In the top, B, above the dframe D, is an-,opening, y,ig. 6, and to bearings on the frame, is, adapted a rock-shaft, G, to which aresecured horizontal armsh 71,', a vertical shaft, H, turning and sliding near its lower 'end in the lower arm h', and turning near its upper end in a bearing, m,

which is arranged to slide horizontally in an opening in the frame D, and a pin, z', projecting from the bearing l m intoa slot in the arm le. At the lower end of the shaft H is a pinion, K', to which motion is communicated from the pinion f through the medium of' pinions 'n n', iig. 1, turning on pins on the frame D, the` pinio'nfbeing of sucha width that it will not be elevated out of gear with the cog-wheel gwhen the frame D is raised or lowered. To a disk, v, at the upper end lof the shaft E, is secured a forming-roller, S, on which Vis an annular rib, t, iig.;7, the roller, above the rib, being inclined and adapted to the bevelled part of a roller, T, whieh is secured to the shaft H, and in which is an annular groove, q, coinciding with the rib t. At the upper edge of the roller T is a flange, u, for a purpose described hereafter. A lever, I, which is hung to one of the cross-pieces 6, fig. 4, is jointed at one end to the lower endof the frame D, the other end projecting beneath the cam d, and on the cam d bears a friction-roller at the lower part of -a slide, K, fig. 5, which moves on a guide at the side of the standard a2. A pin, w, on the slide K, fig, 1, projects into a slot in the weighted arm of a bellcrank lever, J, hung to the standard a?, the other arm, o, of' the lever, which is flexible,` being connected `to the armL of" the rock-shaft Gr.

A rotary motion, imparted in any suitable manner to the cog-wheel g, is transmitted tc the shaft EH and to their rollers S T. As the shaft C, revolves the fran-1e D is alternately raised and lowered by the action of the cam d en the lever I, while, asthe slide K is elevated and depressed by the action of' the cam d', thelevcr J and shaft G are so operated that the shaft H is carried alternately from and toward the shaft E. i While the frame D is depressed, andthe roller S is below the plate B, a metal ring, x, and a flanged disk, x', (which are to besccuredtogether and formed `into a mctal box,) are placed upon the plate B, in the position-shown in red lines, fig. 3, so that when the frnmeDriscs, the roller S will be introduced into the ring x-until the lower edge of the latter rests on thel shoulder formed by the projecting edge of the disk v, as shown in fig. 7. The roller T will noweapproach the roller S, and bearing against the flange of the disk a" and against thelring x, lig. 8,

will cause the same to revolve rapidly, the flange 4u preventing the disk rv from rising, and as the rollers 4are l brought closer together a rib will be formed at the centre of the ring x, the upper edge of the latter will be bent slightly outward, while the flange of the `diskar will be turned inward on to the Banged portionof' the ring i to which the disk is thus firmly secured. Owing to the flexibility of the arm o of the lever K, the pressure upon the ring and disk will be a yielding one, so that the roller T may move back slightly when seams or joints in the metal pass between the rollers. After the disk and ring have been secured together the frame D descends, withdrawing the roller S from the newly-formed box, which rests upon the top B of. the frame, and may be removed to make way for another disk or ring, which is operated on as' before.

It will be seen that the shafts and their rollers are 4maintained perfectly parallel to each other during the whole of the above-described operations. There can, therefore, be no tendency of the disk and ring to separate while being operated on,as would be the case if the rollers revolved at an angle to each other.

I claim as my invention, and desire to secure by Letters Patent- 1. The forming-disks S and T, arranged parallel to each other, caused to revolve in contrary directions, and to move fromand towards eachother, by the aid of the mechanism herein described, or any equivalent to the same, for the purpose specified.

2. The plate B, on which the nnformed box is deposited, in combination with the said forming-disks and' the appliances herein described, or their equivalents, for imparting an intermittent vertie'al reciprocating movement to the disks. Y y

3. The elastic arm o, in combination with the cam'd, and the mechanismlherein described, or its equivalent, for transmitting the motion of the said arm to the shaft H and its forming-disk T.

In testimony whereof` I have signed my name to this specification in the presence of two subscribing witnesses.

JACOB WILD.
