Abstract

171,005. Jacobs, E. Sept. 11, 1920. Reciprocating-punch machines; selective punching-machines.-In punching-apparatus, for perforating papers prior to filing, provided with three or more punches, two of which are selectively operated, the selection is effected by making a flanged plate or lever, by which the domed handle is carried, laterally moving and providing a hole therein, the hole in one position rendering one of the two selective punches inoperative, the other punch not being engaged when the lever is in the second position. Secured to a sheet-metal base-plate 15 are brackets 14 provided with integral lateral rings 21, 22 between which the spring-supported punches 2, 3, 4 are housed. Notches 13 formed in the upper parts of the brackets serve as pivotal points for the punch-operating lever, which is formed from a sheet-metal blank 8 bent upwardly at 12 to engage the notches. Flanges 10, 11 of the blank 8 are made long enough to extend over all the punches, a hole 7 provided therein being situated over the punch 3 to render this inoperative when the lever is in the extreme right-hand position shown in full lines in Fig. 2, the punches 2, 4 then being operated. Notches 30, 31 are provided in the plate 8 to form shoulders 6 in the part 12 adapted to limit the lateral movement of the punch-operating lever, upward movement -of which is limited by a plate 16 carried between the brackets.
