Patent GB-488660-A (GB)
Abstract: 488,660. Calculating - machines. UNDERWOOD ELLIOTT FISHER CO. Jan. 12, 1937, No. 912. Convention date, Feb. 19, 1936. [Class 106 (i)] Relates to an accounting-machine of the kind having totalizers, a travelling paper carriage movable to a plurality of columnar positions, one totalizer being adapted to accumulate a total made up of successively added units respectively entered therein during certain operations of the machine and means for operating said totalizers, in which each of said units is entered into the totalizer when it is in engagement with the operating means therefor, and comprises the feature that the operation to enter a unit into the totalizer is effected independently of the operation of a numeral key under control of the movement of the totalizer into engagement with said operating means. Four totalizers, A, B, C, D are provided and for normal actuation are engaged with actuating racks 2 during the return upward stroke of these racks. The racks are moved downwards by the clockwise rocking of an operating lever 4 pivoted at 5 and having a stud 6 which releases a lever 7 to the action of a spring 8. The lever 7 has a slot embracing a stud 11 on a further lever 9 connected to the actuating racks 2. When the stud has moved to the other edge of the slot, the spring 8, through the levers 7, 9, pulls down the racks 2. When the racks 2 are returned, they are stopped in their zero positions by detent levers 23, 44 and the stud 11 moves to the position shown in its slot, a spring 10 being stressed. If, however, transfer has occurred, the corresponding lever 23 is tripped and the rack 2 moves upwards an extra step. The tripped members are restored at the beginning of the next operation by the clockwise swinging of a bail 22, carried by arms 20, the members 23 being latched by their ends 41 engaging latching slides 37, 38. When the carriage is in a certain position, a lug 27 carried by it is in the path of a slide 31 connected to a lever 29 pivoted on the axis 30 of totalizer A. When the totalizer A is moved into engagement with the actuating racks 2, the lever 29 is thus rocked clockwise and its end 36 lifts the units latching slide 37, 38 to release the units latch 23, the spring 10 then lifts the units slide 2 to add one unit into the totalizer A. The lug 27 is carried on a bar 25 extending the length of the carriage 24 and pivoted thereto at each end 26 so that it can be rocked clockwise to move the lug to ineffective position and thus prevent the entry of the unit, even though the carriage is in the position for such entry. The bar 25 is held in its two positions by a detent 47. One of the uses to which the device may be put is the automatically printing consecutive numbers on bills and receiving only a single horizontal line of entries. After the last of these entries is printed, the machine is tabulated to the next column position where the lug 27 aligns with slide 31. In this position the machine automatically selects the " A " totalizer and executes a cycle. The carriage is then returned to its extreme right-hand position where it again executes a cycle to print the consecutive number. Specification 401,904 is referred to.
