Abstract
893,212. Perforators. FUHRHOP, W. F. Jan. 27, 1961 [Nov. 3, 1959], No. 37269/59. Class 31 (2). In a perforator comprising one or a pair of perforating rods 12 which is or are movable lengthwise through apertures in guard and base-plates 11, 10 by means of a lever 15, the space between which plates forms a slot for the edge of a sheet to be perforated, the guard-plate is formed at least in the vicinity of the rod or rods 12 of transparent material, e.g. polymethyl methacrylate. The guard-plate may be convex to provide a magnified image of the sheet. The base-plate forms the upper wall of a box to receive punchings. The lever 15 may be manually or electrically operated. In a modification, the perforating rod(s) may be arcuate or claw-shaped.
