During the time the circuit was closed, the-solenoid coil 23 was energized and a blow was struck by the hammer ll. When the pressure of the card is removed, the spring 80 restores the bell ‘crank 30 to initial posi_ tion and moves the latch 10 to the right to clear the pin .18 and to reengage the lower end oi the feed lever 54. . _ It thus appears that the operation of the ham~ mer mechanism is initiated by insertion of a card in‘ the card chute and by pressure of the card - against the o?'set portion 32 of the bell crank 30. It further appears that the simple downward dis placement oi said bell crank causes successive cir cuit-closing and circuit-breaking operations to take place which are entirely independent 01’ the operation 01' any other part of the machine. Ii’ for any reason the parts operated by the electro-magnet or solenoid should fail to move, this would have no effect on the closing and open qing of the circuit, which events would take place in definite timed relation and regardless of the movement or lack of movement of any other ma chine part. While I have shown my invention embodied in a machine in which a movable card support is utilized, it is obvious that my improvements would operate in the same manner in a machine in which the card support was stationary. Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set 18 iorth in the claims, but what I claim is: step-by-step, and connections through which in; sertion of ,a card in said chute ?rst tensions said spring-operated means and then releases said means to actuate said star wheel independent of 40. said electro-magnetic meaans. 4.
