Abstract

463,884. Shearing. SMITH, D. Jan. 17, 1936, No. 1519. [Class 83 (iv)] In a shearing-machine with blade C on a member D pivoted on a pin E and terminating in a slot F in which slides a block f actuated from a crank-pin fl, the slot F is non-radial to the pin E in order that the block may move towards the pin E during the last part of the period of the closing of the blades. If p, q, r, Fig. 4, is the locus of the pin f. The point p represents the position of the crank when the cut is nearly complete. At q with the block half way along the slot, the blade is in the lowermost position while at the point r the blades are fully opened. In a modification the slot is arranged in a horizontal extension of the member D.
