ATKINS srovnn, or BROOKLYN, New YORK.
METAL-=SHEARING MACHINE.
SPECIFICATION forming part of Letters Patent No. 329,096, dated October 2'7, 1885.
Application filed Maylfi, 1885. Serial No. 166,576. (No model.)
To aZZ whom it may concern.-
Be it known that I, ATKINS Srovnn, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Shears for Metal, of which the following is a specification.
Shears for metal have been made with a base-block and head-block in one piece, and a bed-shear bolted upon the baseblock and the swinging shear pivoted to the head-block, the Swinging shear moving against a flat face In this form of shear there is considerable friction ofthe swinging shear against the head-block, and the movement of the same is interfered with, and the shear injured by any particles of metalpassing in between the swinging shear and the head-block.
My improvements are made for removing the aforesaid risk of injury and for rendering the cutting-action of the shear more uniform, so that the leverage will be as great in finish ing the cut as in commencing it, and Iprovide a movable gage against which the material to be cut is stopped, as it is passed through, from time to time.
In the drawings, Figure 1 is a side view of the shear. Fig. 2 is an end View of the same. Fig. 3 represents the face of the head-block with the shear-lever and links removed, and Fig. 4 is a section at the line :0 m, Fig. 1.
The baseblock A and head-block B are cast together with an opening at the place where the shears are applied to admit the insertion of the article to be cut. Upon the base-block A are feet or lugs a, by which the shear is bolted to a suitable support. The shear C is received into a recess in the side of the baseblock A, this recess being made with vertical ribs for the shear to rest against. These ribs are easily planed off perfectly true and level for the reception of the shear, and the bolts d are made use of for attaching the shear to the base-block. The swinging shear D is connected to the head-block B by a pivot-bolt, E, which bolt passes through a hub cast upon the head-block. The head-block itself is made with a stiffening-rib along its upper portion, and its vertical surface is recessed for the reception of the swinging shear, and there are Vertical ribs t projecting from the surface of the head-block, against which the side of the swinging shear D moves. These ribs i lessen the friction of the shear against the side of the head-block, and in case of any particles of metal passing inbetween the swinging shear and the side of the head-block the shearis not displaced by the same, as such foreign substances slip off the ribsi into the intermediate recesses. At the end of the head-block B is a joint, H, for the reception of the end of the lever K. This lever is made with a downward projection, is, to which are attached links Z by the cross-bolt 0. These links pass down at opposite sides of the projecting end of the swinging shear D, and are connected thereto by the pivot-bolt n. When the lever K is raised the pivot-bolt 0, swinging in the arc of a circle, assumes a position nearly level with the bolt of the joint H. The shear being wide open at this time, the material to be cut is slipped in almost to the pivot-bolt E; hence, when the lever K is pressed down, the material is cut freely by the leverage of the shear upon such material. As the cutting progresses the point of separation is moved away from the pivot-bolt E, lessening the leverage of the shear against the material being cut, but at the same time the bolt 0, swinging in the arc of a circle down beneath the joint H, the links Z and lever act jointly, like togglebars, to increase the power of the lever K in cutting off the material acted upon, thus equalizing to a great extent the power necessarily exerted in shearing sheet metal or other material.-
In the base-block A is a transverse mortise for the reception of the stock P of the gage Q,
and there is a clamping-screw, r, for holding the stock of the gage in any position to which it might be adjusted. This gage can be set at any desired position for stopping the end of the sheet, rod, or other article that is to be cut up.
I do not claim a gage, or a gage applied to cuttingshears, as these are old and wellknown.
I claim as my invention 1. The base-block Aand head-block 13, cast in one piece and having recesses, and ribs t at the bottom of the recesses, in combination with the bed-shear O in the recesses in the base-block and bolted against the ribs thereof, the swinging shear Din the recess of the head- ICO block and resting against the ribs z, the pivota mortise through it, the stock' P, passing bolt E, passing through the shear and through through the said mortise, the gage Q upon a hub on the head-block, the joint H, lever the stock, and the clamping-screw r, substan- K, links 1, and bolts n 0, substantially as set tially as set forth.
