IPC: G06K13/30
Filed: 1957-09-11
Abstract: 876,324. Selective punching machines. SOROBAN ENGINEERING Inc. Sept. 11, 1957 [June 7, 1957], No. 28717/57. Class 31 (2). [Also in Group XXIV] The high speed punching machine for perforating record members described in Specification 840,114 is modified by an improved ratchet device, Fig. 4, for the feeding mechanism comprising a pawl 64 pivotally carried on an arm 66 co-operating with a ratchet-wheel 63. The pawl is continuously moved up and down, but only engages with the wheel when an electromagnet 78 is energized to attract an armature 77 away from a permanent magnet 80 to rotate the pawl by a link 76 into engagement at the top of its stroke with the wheel 63. A spring- pressed detent 82 locates and prevents backrunning of the wheel while a stop 74 positively checks the pawl and wheel at the end of a stroke. In a modified arrangement, Fig. 10, the pawl 64 is moved into and out of engagement with ratchet-wheel 63 by electromagnets 78 and 94 respectively which move an armature 77 to operate a reciprocating link 92 to engage or release a catch 91 thereon with a bell-crank 88 coupled to the pawl. A spring-pressed detent 82 is provided for the wheel 63 as before, but no stop for the pawl is necessary. In this arrangement the interposers 51 of the punch bail 35 are adapted to be reset by electromagnets 95. This ratchet mechanism also allows of reverse feeding movement by reversal of the direction of drive of the shaft effecting the oscillation of link 67, the pawl 64 then being engaged at the bottom of its stroke.
