Description
UNITED STATES PATENT OFFICEa WILLIAM B. MASON, OF BOSTON, MASSACHUSETTS.
Specification forming part of Letters Patent No. 56,772, dated July 31, 1866.
To all whom t may concern:
Be it known that I, WILLIAM B. MAsoN, of Boston, Suffolk county, State of Massachusetts, have invented a new and useful Machine for Operating Punches, Dies, Shears, 85o.; and I do hereby declare the following Vdescription and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment.
The nature of my invention and improvements consists in connecting two levers by a` link in such a way and manner that as the levers are brought together one will traverse on the other and operate a slide carrying a punch, die, 'shear-blade, or other device.
In the accompanying drawings, Figure 1 is an elevation of my machine, showing one side, and Fig. 2 an edge view.
In these drawings, A is a lever, made in the form shown, or of such other form as will answer the purpose, and provided with two ilanges, J, between which ilanges the slide D is fitted to traverse, and is held in place by the plate M, which is fastened to the flanges by screws, as shown in the drawings.
The slide D has a large head, E, with a dovetailed groove across the end, as shown in Fig. 2, filled with brass, II, .for the hollow punch H to out against. The slide D is traversed to and from the punch by the lever B, made in the forni shown, or in such other form as will answer the purpose, and hinged to the end of the slide. I
The levers A and B are connected by the link O, as shown in the drawings, which link, when the ends of the levers remote from the slide are broughtl together, causes the lever B to traverse on A and move the slide D to the punch H, as shown by dotted lines in Fig. 2, and when the power that closed the levers is withdrawn the springs K and L act to separate the levers and 'draw back the slide D.
The bracket G is fastened to the lever A, as shown in the drawings, to hold the punch II, which is fastened in it with a set-screw, I.
What I claim as my invention and improvement in the above-described machine for voperating punohes, dies, shears, 85o., ils- The combination and arrangement of the levers A and B with the link G, substantially as described.
WILLIAM B. MASON.
