Abstract

456,867. Hand punching - devices. BRACE, WINDLE, BLYTH, & CO., Ltd., and BAYLISS, C. W., 29, Goodall Street, Walsall. Feb. 12, 1936, No. 4194. [Class 31 (ii)] A hand punching- device comprises a body 1 in which three or more punches 7 are mounted in a row and two of the punches are operatedsimultaneously by a lever 12 which is movable axially of its pivot 13 sc as to engage either the two end punches or one end punch and an intermediate punch. The device is characterized by (a) a lever 18 which engages either one end face 24 of the lever 12 or a slot therein to hold it in adjusted axial position and (b) a spring-pressed headed pin 25 which assists upward movement of the lever 12 and limits its downward movement. A hole 16 is positioned over the punch 7 which is not to be operated. A wire gauge 5 is adjustable in the base 3 for positioning the work.
