Abstract

192,534. Jardine, Sir E., and Cohen, I. Nov. 25, 1921. Crank linkages for providing a quick return stroke in a paper-cutting guillotine. A knife B in a holder A is reciprocated by a connecting rod C journaled to a 'crank pin D revolving round a fixed shaft F. A wheel H driven through gearing from a shaft L has a crank pin K turning about shaft J out of alignment with the shaft F. The pins D, K are connected by a link M. In operation, the pin K is the driver and causes the cutting stroke to be completed in two thirds of its time of revolution.
