Abstract

716,656. Calculating-apparatus. BRUNSVIGA MASCHINENWERKE AKT.-GES. April 28, 1952 [May 23, 1951], No. 10672/52. Class 106 (1) A ten-key adding machine has a pin carriage a to which is secured a comb-shaped plate b the teeth of which normally lock the differential actuators of higher orders than those co-operating with the pins of the pin carriage but free the actuators for total-reading purposes when the carriage is shifted half a step. The pins are so spaced that when the carriage is so shifted, they do not obstruct the actuators. An amount set on the pin carriage may thus be preserved, so that it is possible to read an intermediate total during a division process.
