Abstract

155,613. Ashton, T. R. R. June 30, 1919. Shearing.-In shearing-machines actuated by a hand-operated pinion and a toothed sector, both this and the axis of the pinion move during the operation. One blade a, Fig. 2, is formed with teeth and the other carries a pinion f<1> in engage. ment therewith. The blades are pivoted by a bolt c, guided by bolts e, e<1> of the frame, and have notches a<1> and holes a<2>, a3. a<4> for cutting rods, wire, &c. In a modification the bolt c passes through the frame, which has apertures to allow wires to be inserted in the holes a<2>, a'. In another modification a lever h, Fig. 5, carries a pinion p<1> and has a fixed pivot i and a detach. able blade h<1> adapted to co-act with a fixed blade g', and a sector lever o has a fixed pivot n and a short arm o<2> engaging a similar arm of the lever h.
