Abstract: 503,015. Accounting - - machines. NATIONAL CASH REGISTER CO. Sept. 24, 1937, No. 25920. Convention date, Sept. 25, 1936. [Class 106 (i)] Splitting-machines.-In a cash register or similar accounting-machine in which the key. board for additive data is split into a plurality of groups of banks, each group being associated with a totalizer (or totalizers) and wherein data set up on each of the groups are entered simultaneously into the corresponding totalizers by means of differential mechanisms associated with each of the banks, the overflow denominations of all the totalizers are positioned to co-operate with a single differential mechanism for transfer and total-taking purposes. The invention is described as applied to a machine having four rows of interspersed totalizers and transfer mechanism of the kind described in Specification 468,506. In addition to the usual amount keys 10, Fig. 1, the machine is now provided with a group of quantity keys 11 also associated with totalizers, the overflow denominations both of the amount and of the quantity totalizers being situated at the left-hand ends of the totalizer rows to co-operate with the usual overflow differential mechanism situated at 12. In addition to the groups of amount keys 10 and quantity keys 11, the machine is provided with four banks of totalizer-selecting keys. Of these, the first bank 101 selects quantity totalizers situated in row I, Fig. 5, while the second 201 selects amount totalizers in row II, Fig. 4. Corresponding keys in these banks are connected by bridges 161, pivoted to the keys 101 and spring-latched to the keys 201, the arrangement being such that the bridges may be lifted to permit adjustment of the usual lever used in selecting a totalizer for total-taking. Interlocks between the keys of the first and second banks enforce the depression of a quantity key 101 before the corresponding amount key 201, which latter releases the machine. As is seen from Figs. 4 and 5, the overflow denominations of the quantity totalizers in row I are situated in the usual position, whereas the overflow denominations of the amount totalizers in row II are spaced from the remaining denominations and situated in the planes of the overflow denominations of row I. Transfer to the overflow denomiiiations of the amount totalizers, Fig. 4, is effected by duplicating the usual transfer pinions 41 between these and the denominations of next higher order, and connecting these pinions by rigidly attaching them to the transfer shaft 50. The keys 301 of the third bank, simultaneously select corresponding amount and quantity totalizers situated in row III (not shown), this row being split by the omission of transfer mechanism between the highest amount order and lowest quantity order. Amount totalizers in this row have no overflow denomination. The keys of this third bank also act as release keys. The keys 401 of the fourth row are transaction keys and select amount totalizers in row IV (not shown), which totalizers are arranged in a similar manner to those in row II, Fig. 4. The machine may be provided with printing-mechanism of the kind disclosed in Specification 387,032.
