Abstract

885,904. Perforating machines. YERKES, J. A. May 16, 1960, No. 17248/60. Class 31(2). A perforating machine comprises a plurality of punch head assemblies 45 mounted on a base 1 and movable along a rotatably-mounted shaft 37 oscillatable about its axis by means of a handle 39, the shaft having a longitudinal groove 38 associated with a circular tooth 93 on the reciprocable punch pin 48 of each punch head assembly, and the shaft 37 being cut away at intervals, with corresponding gaps in the wall 103 of the groove 38, to form neutral zones 95, 96 so that when the handle 39 is operated, only the punch pins of those punch head assemblies which are not positioned opposite the neutral zone or zones will be reciprocated. To facilitate positioning of the punch head assemblies, they are each provided with an index line 94 co-operable with a scale 14 on the base 1, the scale including arrowheads 101, 102 located opposite the centres of the neutral zones. Each punch head assembly is slidably mounted on a flange 8 formed on the base 1 and is releasably secured in position by means of a set-screw 65. The material to be perforated is positioned by means of a front gauge 20 and rear gauges 67, the front gauge being frictionally held by means of a spring 22 and locked in position by means of a manually-operable cam 30. Punchings are received in a detachable receptacle 109.
