656,185. Calculati ng-apparatus. HERZSTARK, C. Dec. 31, 1947, No. 35028. Convention date, March 7, 1946. [Class 106 (i)] Calculating - apparatus in which numeral drums and actuating elements respectively of a totalizing counter and a revolution counter are arranged in circles around a common driving element is characterized in that the numeral drums and actuating elements respectively of the two counters are arranged in two groups on their respective circles separated by angular gaps, so that the two counters show two separate number groups in the plane of the circle of the numeral drums. A stepped tooth drum W, Fig. 8, is driven by a crank 29, Fig. 1, pinned to its shaft 2 and drives, through a set of teeth Z<SP>1</SP>, entering members 3 for a totalizing counter R, Fig. 3, and through a tooth Z<SP>2</SP> the first entering member 4 for a revolution counter U, the other entering members being for a purpose not described. Numeral drums 9, 91 with their transmission pinions 8, 8<SP>1</SP> and actuating elements 10, 11 of the two counters are arranged in circles, the numeral drums 9, 9<SP>1</SP> and pinions 8, 8<SP>1</SP> being mounted in a carrier which is slidably and rotatably mounted in the body 1 for denominational shift, the parts being so spaced that when the carrier is turned so that numeral drums of one counter come into the zone of actuating members of the other counter, the corresponding pinions 8, 8<SP>1</SP> do not mesh with pinions 11, 10. A pin 12 engaging a recess 13 in the carrier provides justifying means.
