Abstract

200,439. Waldschmidt, R., Waldschmidt, R., and Waldschmidt, H. Nov. 22, 1922. Selective perforating machines. - In an apparatus for perforating letters for filing, with two holes at varying distances apart, a handle f actuates, through traction links e, e<1>, a crossbar d with holes i, i<1> for the free passage of punches b, c and a stopped hole for a punch a. A sleeve d' journaled in the links is slidable over the crossbar and carries a hole h and slots g so arranged that when the hole h registers with either of the punches b, c that punch is rendered inoperative. In a modification, the crossbar and the sleeve are interchanged and the crossbar made movable. In further modifications, the sliding tube comprises a short sleeve extending the distance between the punches b, c or the sleeve instead of sliding axially may have a rotary movement.
