Lb all whom it may concern:

Be it known that I, RALPH BAGGALEY, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Machine for Stamping Copper, of which the following is a full and exact description, reference being had to the accompanying drawings, in Which Figure 1 is a plan view of the apparatus in its preferred form. Fig. 2 is a side view, partly in section. Fig. 3 shows a ratchetwheel and pawl for holding in position the supporting-piece for the pig or other metal article to be stamped. Fig. 4 shows in crosssection a table with the supporting-block for the pig, together with the chute into which the pig is dumped after stamping. Fig. 5 is a side view, partly in cross-section, of a modification in which mechanical pressure supplied by an eccentric, toggle-joint, or other device is substituted for the power-cylinder shown in the other figures.

The object of my invention is to provide means for stampin weights, owners names, &c., on pigs or p ates of copper or other metals practically Without hand labor, and I accomplish this result in my preferred form of apparatus by means of hydraulic, steam, or air pressure and in my alternate form of apparatus by mechanical pressure, produced by a cam, eccentric, toggle-joint, or other device. In each instance I preferably arrange the die that carries the letters or figures to be stamped so that when the latter have been forced into the piece to the requisite depth a greatly-increased area ofdie-surface will be brought into contact with the piece and will stop the travel of the die. I may also supplement this by employing other stop mechanism.

. My present invention constitutes one of a series of inventions made by Ralph Baggaley and E. W. Lindquist which make it possible to prepare copper pigs and plates for shipment more cheaply and expeditiously than has heretofore been possible.

In the drawings, 2 represents the table upon which the copper pig or other piece is dumped after it leaves the fin-trimming machinery and weighing-scales. It then rests upon a rotatable supporting-block 3, preferably of star shape, illustrated in cross-section in Fig. 4, which is locked in position by locking mechanism 3, such as shown in Fig.

3. When in this position, it is in direct line or register with the dies 4 5. (Shown in Fig. 2.) One of these dies is carried at the end of the piston 6 of a cylinder 7, actuated by fluid, whether steam, air, or water, and the other die is carried by a stem 8, which is movable lengthwise by a lever 9 and is backed by an adjustable eccentric stop 10. Pressure is then applied to the cylinder, which causes the piston to move the die forward and to engage the end of the pig, preferably on a sunken rosette 11 thereon that has pre viously received a finishing cut. The endwise movement of the pig is limited by means of the resistance mechanism 10, so that when the limit is reached the pressure of the die l will sink the letters or figures into the finished rosette, and when they have been fully embedded the increased die-surface which thereupon engages the rosette effectually prevents further movement of the piston and the die. When the stamping operation is finished, the supporting-block is turned by a handle 12, Fig. 2, and the metal pig is discharged into a chute 13, Fig. 2, along which it travels to a conveyer or other mechanism for storing it or delivering it for shipment.

The stamping mechanism shown in Fig. 5 is similar to that above described except in the means for applying and resisting the pressure. In this machine the die 4 is actuated by an eccentric 14, which may be replaced by a toggle-joint or other device. Owing to possibly varying lengths of the pigs or plates into which the metal is cast, and owing also to the rigid movement of the camactuated machine, I provide a heavy spring 15 to bear against the die 5, and thus to receive and to resist the pressure. The spring is capable of adjustment at will, and its resistance to the pressure must be greater than the power necessary to embed the letters or figures in the piece. Any surplus movement of the die 4 will therefore be absorbed by the spring.

Doubtless many variations in the arrangement of the details of this apparatus will suggest themselves to those skilled in the art without departing from the spirit of my invention, since What I claim is 1. Apparatus for stamping, comprising a die and means for moving it, an opposite resistance-piece, and a rotatable support for the article to be stamped; substantially as In testimony whereof I have hereunto set described. my hand.
