Abstract

151,970. Ciliax, W. July 1, 1919, [Convention date]. Shearing.-A handoperated shearing and punching machine has an intermediate linkage connecting the handlever to the toolslide operating levers. One end of each of a pair of tool-slide operating-levers c is connected to the hand-lever h, the other end being pivoted on the frame, the tool-slide a being linked to the operating-levers. The hand-lever carries rollers i engaging a pair of links f pivoted to an extension e of the frame. A pair of intermediate links g unite the hand-lever h and the links f. The faces of the links f engaged by the rollers may be arcuate. Positive return of the press-bead is obtained by the engagement with slots f<1> in the links f, Fig. 4, of a pin h<2> carried in a lug on the hand-lever. A punch may be actuated by the tool-slide.
