Abstract
720,943. Document perforators. SACHS, L., [trading as METALLWARENFABRIK H. SACHS, INHABER DR. L. SACHS]. April 30, 1953 [Nov. 3, 1952], No. 11963/53. Class 31 (2). In a document perforator having four punches arranged in a row in two pairs, the operating lever j is provided with a longitudinally movable U-shaped slide m extending over all the punches, the slide having apertures n, o, p so that by suitably moving the slide, all four punches, the two outer punches, the two inner punches, or the outer punch of one pair and the inner punch of the other pair may be rendered effective during the operation of the perforator. These four positions may be marked on the slide so as to be visible through an aperture in the operating lever. Further, teeth may be mounted on the perforator to indicate the centre points of the hole spacing.
