Abstract: 921,390. Transfer mechanisms. OLYMPIA WERKE A.G. March 2, 1960 [March 3, 1959], No. 7393/60. Class 106 (1). In a tens-transfer arrangement for calculating machines in which the actuators remain in engagement with the register and execute an additional movement for transfer, a control segment is provided for each digital order, which segment can be released for movement by a tens cog on a register wheel and which carries a pawl coupling the actuator in the next higher order to a control bar common to all the digital orders, the segment also having a stop and a projection, the projection being displaceable by the associated tens cog to coact with the stop on the control segment in the next lower digital order. As described, there is provided for each digital order, an actuator 2 and, for each order except the highest, a control segment 13, the actuators 2 and control segments 13 being pivoted on a shaft 1. Values entered on keys are set up in pins 11 in a pincarriage 12. During the first half of a machine cycle, a bar 10 is rotated counterclockwise about the shaft 1 to allow the actuators 2 to rotate under the action of springs 9 until stops 2a thereon contact the set pins 11. Typebars 7 which have been correspondingly rotated are then pivoted to print the set value. The machine has two registers I and II, the required register, for instance I, now being swung to mesh its additive wheels 3 or subtractive wheels 4 into engagement with the actuators 2. Assuming that the additive wheels 3 are engaged, the bar 10 is rotated clockwise about the shaft 1 to transfer the set up value additively into the register I. If, during this operation, a gear wheel 3 passes from " 9 " to " 0," a cog 3a thereon briefly rocks a lever 26 pivoted on a fixed shaft to deflect a pair of intermediate levers 14, 15 on the control segment 13, an extension 15b on the lever 15 swinging a release lever 16, on the segment 13, clockwise to release one end 16a thereof from a fixed rail 18 and engage the other end 16c thereof in a catch 17 also on the segment 13. A control rod 24 is now pivoted clockwise about the shaft 1, those segments 13 only whose release levers 16 have been tripped and in respect of which a projection 14b on the lever 14 has returned to its initial position in which it does not coact with a stop 13a on the segment 13 of lower order, following the rod 24 under the action of springs 22. For such segments 13, a pawl 21 thereon pivots when a bar 23 lies against a recess 21c in the pawl, such pivoting causing a bent portion 21b to abut a projection 2b on the actuator 2 of next higher order, further movement of the rod 24 causing the actuator of next higher order to step on its associated register wheel 3 by one digit, thereby effecting transfer. The register is now brought out of engagement with the actuators, the return movement of the bar 24 returning the segments 13 to their initial position. Finally, a rocker 25 resets the lever 16. Transfer through several denominations is effected since when a register wheel 3 registers " 9," the associated lever 26 is maintained rocked so that the corresponding projection 14b on the lever 14 lies in front of the stop 13a on the segment 13 of the next lower digital place. Thus the higher order segment 13 can only turn if the lower order segment turns, i.e. a through carry is in question. A stop corresponding to the stop 13a is provided on the machine frame for the lowest denomination.
