Abstract: 328,667. Florenz Waagen-und Gewichtefabriks-Akt.-Ges., J., and Kravits, A. Jan. 21, 1929. Cash registers.-In a cash register or calculating machine having a single bank of ten numeral keys and a plurality of totalizers, the numeral keys are utilized in the selection of a totalizer, and in the printing of a total and simultaneous zeroizing of the selected totalizer. Differential mechanism.-The cash register described is of the key set and operated type having a single bank of numeral keys 3, 3', Figs. 1, 2 and 14. Each key is rigid with a toothed sector 4. the number of teeth on which is equal to twice the value of the key. Upon depression of a key, the corresponding sector engages and differentially sets a toothed drum 5, the setting of the drum being communicated through a common actuator wheel 9, mounted on a carriage 8, to the counter wheels of one of a series of totalizers 10. The keys are reset by a bail 29, upwardly urged by wires 31 wound on spring drums 33. The carriage 8 istraversed by a toothed plate 23, that is slidably disposed below the carriage and oscillated upon depression of the keys through the agency of a stepped bail 20 rigid with the shaft 2 upon which the keys are pivoted. A projection 27, Fig. 6, on the carriage is engaged successively by teeth 25, 26 on the plate, the arrangement being such that the wheel 9 engages a wheel of a totalizer during the depression of a key but, during the return movement, is idly disposed' between the wheel last engaged and the wheel of next lower denomination. The position of the carriage is indicated by a pointer 119 registering with a chart 120, Fig. 14. The carriage may be returned to any desired position of higher denomination by depressing a key 122, disposed within an aperture 121 in the casing and connected indirectly to the carriage. Totalizer-selecting mechanism.-Nine totalizers 10 are arranged at equal intervals around the periphery of a drum 11, rotatable about a shaft 36 through pinion 49 on gear 50. To select a totalizer, the carriage 8 is adjusted to a position one step below the totalizer wheel of lowest denomination, in which position the actuator wheel 9 meshes with the gear 50, so that depression of a key moves the totalizer of corresponding number into operative position. The drum is held in set position, against the action of a return spring, by a detent 51 engaging one of a series of notches 52 in the periphery of the drum. The drum 11 is allowed to return to its initial position by the disablement of the detent 51 by a projection 53, Fig. 6, on the carriage 8, on each occasion that the carriage 8 passes into the totalizer-selecting position from the position corresponding to the lowest denomination of the totalizers. Two totalizers 37, 38 accumulate the amounts entered into the individual totalizers 10, being actuated by a wheel 19 carried by the car. riage 8 and geared to the wheel 9. These totalizers 37, 38 may be independently moved into and out of operative position by knobs 37<1>, 38<1>, projecting through slots in the casing. Transfer-mechanism.-Transfer is effected by a pair of projecting teeth 40, Figs. 8 and 16, on the wheel of lower denomination meshing with a transfer pinion 43 that is mounted on a spring- urged lever 45 and rigidly connected to a second pinion 44 meshing with the wheel of higher denomination. Incorrect action is prevented by a projection 48, Fig. 6, on the carriage 8 that disables the transfer pinions of next lower denomination. Similar projections are provided for the totalizers 37, 38. The pinions of all higher denominations than the wheel actuated, are held in engaging position by a bar 137, Fig. 16, carried by the carriage. Item-printing mechanism. - The items are printed on a record strip retained within the machine by means of a type-wheel 15, Figs. 2 and 3, slidably mounted on the squared left-hand end of the shaft 5<1> of the toothed drum 5. Additional numerals corresponding to the totalizer selected and to the class of goods are also printed. The items are printed across the strip, the spacing of the numerals in the item being effected by a rack 73, that carries arms 72 embracing the type-wheel and is connected to the carriage 8 through reduction gearing 75, 76, Fig. 6. Ink is supplied to the type-wheel from a roller 69 a.nd printing effected by a printing- hammer 77 moved upwardly upon depression of a numeral key. The strip is fed from a roll 81 on to a second roll 82 by means of an arm 83 extending from the shaft 2 and carrying a pivoted arm 84 terminating in a transverse rod 85 that bears on the surface of the rolled paper and engages within a sector-shaped recess 88 in a freely rotatable disc 87, movements of which are communicated through a pawl 89 to a ratchet wheel 86 connected to the roll 82. Voucher-issuing.-At the opposite side of the machine to the item-printing mechanism described above, means are provided to print a duplicate of the entry on a voucher that is subsequently severed from a strip and ejected from the machine. The numerals are printed by a typewheel 16, Figs. 2 and 4, and the items arranged longitudinally of the voucher, which is fed after each movement of the printing-hammer 99 by feed rollers 102, 103 actuated from the hammer through a ratchet 106. The numerals corresponding to the totalizer selected, the class of goods and the item, are spaced apart by shifting the type-wheel axially, the three positions being determined by the position of the rack 73. The voucher is ejected by depressing a key 109 connected through lever 108 to a rack 110 meshing with ratchet-teeth on the feed roller 102. At the end of the downward movement of the key 109, a projection 111 thereon actuates a knife 107 to sever the voucher. Advertising or other matter may be printed on the reverse side of the voucher by type on the feed roller 103. Printing totals.-In order to take a total from a selected totalizer, the carriage 8 is traversed to its extreme right-hand position where it meshes with the totalizer wheel of highest denomination. In this position a bent lever 113, Fig. 6, on the carriage engages and is rotated by a stop 114, Fig. 2. The " nine " key is depressed until the totalizer wheel is reset to zero, when a stop 41, Fig. 8, on the wheel abuts the end of the lever 113. The complement of the digit of highest denomination is then indicated on a chart 116. Fig. 14, disposed adjacent the " nine " key. On release of the key the parts return to their set position. The key corresponding to the abovementioned complement is then depressed and results in the zeroizing of the totalizer wheel and the traversing of the carriage 8 to the totalizer wheel of next lower denomination. The operation is repeated for each wheel of the totalizer. The total is printed by a second set of type on the wheels 15, 16, which set is complementary to the main set and interpolated therebetween. The type-wheels are rotated to bring the second set of type into operation by a handle 117, Figs. 3 and 14, operation of which rotates the drum 5 and wheel 9 through one tooth. During a totaltaking operation the transfer mechanism is ren. dered inoperative, by a stop 48<1>, Fig. 16, that is rotated by the total-taking lever 117 into a position in which it disables the transfer pinions of next higher denomination. At the same time, the bar 137 integral with the stop 48<1> is rendered inoperative. Operation counters. - The number of times that a total is taken is indicated by a counter actuated by the handle 117. Differentially-moved indicators. - The items entered are indicated to the customer and operator by drums 17, Fig. 1, viewable through windows 57, 57<1>. The drums are actuated from the common actuator wheel 9 through wheel 19 and gears 59. and are braked to remain in set position. The indicator is reset by sliding a knob 66, Fig. 14, connected through a rack 64 and pinion 65 to a bail 62 engaging stops 63 on the peripheries of the drums. The rack 64 is elongated to engage the " nought " key 28, so that when the indicator is cleared the totalizer drum 11 is reset. Cash-drawer mechanism. - The cash-drawer 123, Figs. 1 and 11, is urged outwardly from the casing by a pair of springs 131, 132, acting on frames 126, 127 that are pivoted to the drawer and are provided at their free ends with rollers 128 engaging curved channels 129, 130 on the casing. The drawer is retained in closed position by a latch 133 which is disabled by a stop 134 on the carriage 8 as the latter passes into the totalizer-selecting position.
