IMPROVEMENT IN CAN-SEAMlNG MACHINES@ Specification forming part of Letters Patent No. l 50,607, dated May 5, 1874; application filed December 17, 1873.

CASE E.

To all whom it may concern:

Beit known that we, JAivrEs H. PERKINS and GEORGE H. PERKINS, of Philadelphia, Pennsylvania, have invented a Machine for Closing the Scams of Sheet-Metal Cans, of which the following is a specification:

The object of our invention is to close the bottom and top seams or joints ot' square sheetmetal cans, by combining a table, E, and devices for retaining the can A on the same, with two connected and guided slides carrying rollers, by the pressure ot' which the opposite seams of the can can be simultaneously closed, in the manner fully described hereafter, and as shown in the perspective view, Figure 1, of the accompanying drawing.

In the present instance a pressure-plate, F, is hung to the outer end of an arm, G, which is jointed to a rod, H, arranged to slide in a socket formed in the stand I, and containing an adjustable spring for supporting the rod, so that the plate F, when depressed, will accommodate itself to the top of the can. The sliding frame consists of two bars, B B, adapted to guides D D, and connected together by rods b, so bent that they can pass over and free from contact withl the can, pressure-plate, and arm G, the rods themselves being connected together by cross-bars b', forming handles by which the operator can grasp the frame and move it to and fro in its guides. The bottom n of the can, bent at its four edges, as shown in Fig. 2, is placed on the table E, between the guides D D, and the larin g lower end of the body of the can is placed on the bottom within the turned-up edges of the latter, after which the operator depresses the arm G 'by means of a rod, H', and a treadle or other suitable appliances, so asto cause the plate F to bear on the top of the can, and to maintain the latter steadily on the table, while the pressure-plate F above the top of the can,

which' can be removed, turned, and placed in such a position that the two remaining seams can be closed by a second movement of the sliding frame, after which the can can be rcmoved and soldered.

We do not conne ourselves to the pressureplate F or other device for applying pressure to the top of the can, as the latter might be confined to the table with sufficient iirmness by devices adapted to its sides or end; nor do we claim, broadly, a. roller for closing the seam of a can; but

We claim as our invention- A table or bed, E, and devices for retaining a can thereon, in combination with the two connected and guided slides B and their roll ers, the whole being constructed substantially as set forth, so that the said rollers can be brought to operate simultaneously on opposite seams of a square can.

In testimony whereof we have signed our names to this specification in the presence of two suhscribin g witnesses.
