Abstract: 418,536. Calculating-machines. HILSCHER, E., 8, Katharinenstrasse, Chemnitz, and HEINITZ, K. R., 4, Friedensstrasse, Dresden, both in Germany. Sept. 29, 1933, No. 26851. Convention date, Oct. 24, 1932. [Class 106 (i).] In a calculating machine, a rocking member is set by keys to differential angular positions and forms a guide along which a member is reciprocated by the main driving mechanism, the member imparting to the totalizer during one reciprocation a movement depending on the setting of the rocking member. Setting and actuating mechanism. The differential movement of a bar 11 obtained by depressing keys 10 having pins engaging different slopes on the bar is transmitted by a lever 13 and link 14 to a rocking member 1 pivoted at 2. A pin 6 is traversed along a slot 3 in the member 1, when the main shaft 16 is operated, by a cam 17, lever 18, link 19, lever 20 pivoted at 40 and link 21. Depending upon the amount the member 1 has been rocked by key depression, a link 7 carried by the pin 6 actuates a segment 8 pivoted on a bell-crank 9 which is rocked by a cam 22 to bring the segment 8 into engagement with pinions 23 or 24 gearing with a totalizer 66. The pinions 23, 24 are connected by gearing but are in different planes and are slidable so that either the set 23 or the set 24 can mesh with the sector 8, whereby the item is entered either additively or subtractively. Operation counters.-The lever 20 pivoted at 40 carries a link 42 pivoted to a segment 36 which is brought into engagement with add or subtract pinions 38, 39 of an operations counter 66<11> when a bell-crank 37 is rocked from the bell-crank 9 by a link 28. With several totalizers.-A second totalizer 66' is actuated by a segment 25 connected to the segment 8 by a link 26. The segment 25 is pivoted to a bell-crank 27 which is rocked by a link 29 to move the segment into engagement with the totalizer pinions. The connection between the link 29 and bell-crank 27 may be disabled at will. Transfer mechanism.-When a numeral wheel passes through zero a cam 65 depresses a lever 64 which in turn depresses a lever 57 until a pin 58 thereon is held in the lower of two notches 60, 61, in a detent lever 59. The lever 57 carries a pin 56 situated in the slot 55 of a link 49 which, with another link 48, forms a toggle connected by a link 50 to a lever 52 rocked by a cam 53 on the mainshaft 16 at each machine operation. When the lever 57 is depressed, due to the corresponding numeral wheel passing through a transfer point, the pin 56 is moved to the left-hand end of the slot 55 so that when the link 50 rises the pin 56 forms a stop for the end of the link 49 and thus the link 48 rocks a lever 47 pivoted at 70 and connected by a link 46 to the end 42 of a lever 43 of the next higher denomination and corresponding to the lever 7 of Fig. 1. This end 42 has a cam slot 44 surrounding a pin 4 on the actuating segment 8 and when the link 46 is raised the slot causes the pin to move the segment, and hence the numeral-wheel pinions one step. The Specification as open to inspection under Sect. 91 describes also a modification in which a bar can be engaged with pins on the lower ends of the member 1 and of the actuating segments 8. This bar is connected to type carriers which are thus positioned in accordance with the setting of the members 1 or 8. This subjectmatter does not appear in the Specification as accepted.
