Abstract
1,221,755. Ten key calculating machine. ADDMASTER CORP. 19 March, 1969 [24 April, 1968], No. 14452/69. Heading G4B. A ten key cyclically operated calculating machine having differential actuators 26 and a movable stop-pin carriage 13 has co-operating surfaces 61, 62, respectively, on the actuators and pins 14 which cam set-pins from their set positions so as to enable the carriage to move back to its original position before the actuators have been fully retracted. The machine is a modification of that disclosed in Specifications 971,662 and 975,856. Each actuator 26 has a chamfered edge 61 as have two adjacent gear teeth 35 at point 59 so that the edges engage with the chamfered edges 62 of the set stop pins 14 and the pins are cammed over the actuators. Where a pin is not cammed by an actuator it is cammed into its retracted position by a stationary cam member on the machine frame.
