specification forming part of Letters Patent No. 146.947, dated January 27, 1874; application filed December 17, 1873.
lAsE O.
To all whom it 'may couccrn:
Be it known that I, Janus H. PERKrNs, of Philadelphia, Pennsylvania, have invented a Machine for Olosing the Seams of Sheet-Metal (lans, of which the following' is a specification:
My invention relates to the manufacture of the square cans used for the transportation v and storin g of petrolenm and other fiuids and the object of my invention is to close the seams at the`jnnction of the bottoms and tops with the bodies of such cans, at four sides simultaneously, by the combination of a pressureplate, D, and yielding bed A, for confining and depressing the can, with plates B, for operating 011 the seam of the can during the depression of the same, all as fully described hereafter, and as illustrated in the Vertical section, Figure 1, and plan view, Fig. 2, of the accompanying drawing.
A spindle, a, to which the said bed A is attached, passes through and is gnided by a table, F, and a cross-bar, (Z, of a suitable frame, (i, which supports the table; and a collar, b, on the spindle bears upon aspring, E, supported by the said cross-bar. The pressureplate D is suspended from the upper end of a bent rod, H, the lower end of which is connected to a treadle, I, a spring, J, tending to elevate the rod, pressure-plate, and treadle after the latter has been released from the pressure of the operatorls foot. To the table F are hinged the four plates B, one opposite each edge of the square bed A, and a-t the onter edge of each plate are two fianges, m and n, as best observed in the enlarged sectional views, Figs. 3 and 4, the flanges a of the plates being below and the fianges m above the beveled edge of the bed.
The bottom e of the can, in the conditionof a square plate with its edges turned np, as shown in Fig. 1, is placed on the bed A, while the latter and the hinged plates B are ele- Vated, and the lower fiaring end of the body f of the can is placed on the plate e, within its turned-np edges, after which the operator depresses the treadle, the first effect of the pressnre on which is to cause the plate D to sccnrely confine the bodyf and bottom c of the can to the bed. On continuing to depress the treadle, the bed A must yield, and the hinged plates B must be gradually moved from the inclined position shown in Fig. 3 to that seen in Fig. 4. The action of the fianges m of the hinged plates during this moveinent will be to turn inward simulta-neously all the four flanges of the bottom c against the flaring lower ends of the body, and then to turn both these fiaring edges and the turned-up edges of the bottom c together against the beveled' edges of the bed A. On releasing the treadle, the recoil of the spring E will elevate the bed to its former position, and the spring J will elevate the pressure-plate D, so that the can, with the bot-tom c firmly secnred to the body, can be removed, the joints being ready for soldering. Springs w, secured to the under side of the bed A, and bearing against the fianges n of the hinged plates, tend to restore the latter to their proper position after the release of the treadle.
I claim as my invention-` 1. The pressure-Mate D and yielding bed A, for coniining` and depressing the can, in combination with plates B, constructed substantially as described, for Operating on the sea-m of the can during the depression ot' the same.
2. The combination of the yielding bed A, the plates B, hinged at one end to the table or other permanent part of the machine, and the springs w.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
JAMES H. PERKINS.
