Abstract

1299961 Controlling pin carriage shift TOKYO ELECTRIC CO Ltd 6 Feb 1970 [6 Feb 1969 20 Feb 1969 (3) 21 Feb 1969] 5885/70 Heading G4B The Specification describes some "of the features of the calculating machine described in 1,299,744. The claims relate to the shifting of the pin carriage during the order-by-ordor setting up of a number. Each shift is effected in two parts, which together amount to a shifted distance corresponding to one order. As shown, depression of any digit key 19 results not only in depression of the corresponding pin, but also in the pivoting of a lever 20, the head 21 of which depresses the carriage escapement pin 4 of the appropriate order. This pin is now clear of a stop 12 and the carriage moves leftwards under a spring-loading until the next lower order escapement pin 4 abuts head 21. On releasing the digit key 19, lever 20 pivots clockwise allowing this next lower order escapement pin 4 to move past the head 21 into engagement with stop 12. The escapement pins 4 serve also as digit nine pins.
