UNITED STATES ALFRED LEE, OF FOREST GROVE, OREGON.
IMPROVEMENT IN MACHINES FOR PUNCHING AND SHEARING METAL.
Specification forming part of Letters Patent No 190,771, dated May 15, 1877; application filed March 19, 1877.
To all whom it may concern:
Be it known that I, ALFRED LEE, of Forest Grove, in the county of Washington and- State of Oregon, have invented a new and Improved Punching and Shearing Machine, of which the following is a specification:
Figure 1 is a side elevation of my improved machine, with parts broken away to show the construction more clearly. Fig. 2 is a front elevation.
Similar letters of reference indicate correspondingparts.
My invention consists of a togglejoint and two hand-levers, and a peculiar arrangement of links for connecting the same, in combination with a punch and shears.
The object of the invention is to provide a machine for punching and shearing metal that shall be compact, strong, and effective.
In the drawing, A is the main standard of the machine, having the flanged base-piece a, and from' which projects the lower or fixed jaw B of the shears. Through a mortise in this jaw the punch-follower (J passe-s. A reccss, D, is made in the standard A, below the jaw B, at the lower side of which. the die I) is secured. A spring,c, is attached to the under side of the jaw B, and presses against a shoulder of the follower O, which it forces upward. The upper or movable jaw E is pivoted to the standard A at d,.and its cuttingedge is capable of moving past the edge of the jaw B. The under surface of the square portion 6 of the jaw E bears uponthe upper end of the punch-follower 0 when the jaw is moved downward. F F are vertical standards attached to the jaw B, in the upper ends of which the upper end of the lever fof the toggle G is pivoted. The lever g of the toggle is pivoted at h in a mortise in the part c. A bolt, 5, which is the fulcrum of the lever H, passes through the standards F, and also through .links j, that run backward and receive the bolt upon which the lever I is fulcrumed. The short arm of the lever H is connected with the leverf of the toggle by a link, k, and the short arm of the lever I is connected by a curved link, 1, with the joint of the toggle. The link I is secured in the lever I by the removable pin m, which is taken out when it is desired to use but one lever to operate the machine.
By moving either or both of the levers H l, the toggle-joint G is straightened, and the jaw E moved downward with sufficient force to shear metal placed between the jaws E B, or to punch anything placed on the die in the recess in the standard.
Having thus described my invention, I claim as new and desire to secure by Letters Patent-- The combination of the jaws E and B, follower C, standards A and h, toggle G, levers H I, and the connecting-links j k l, slybstantially as herein shown and described.
ALFRED LEE.
