Abstract: 441,471. Cash registers. COMPAGNIA EUROPEA REGISTRATORI S. A. I., 1, Corso Littoria, and CAMPANA, G., 3, Via Ozieri, both in Milan, Italv. Mav 17, 1934, No. 14906. [Class 106 (i)] Differentially - moved indicators.-In a lever-set crank-operated cash register having means for printing on a record strip and inserted card and wherein the setting of the levers is transmitted to the indicating and totalizing devices by means of bands or chains, the indicating device comprises denominational pairs of flexible bands 6, 10, Figs. 1 and 4, the bands of each pair being connected at their inner ends to one of the setting levers 3 so as to display the amount set up to the operator and purchaser through apertures 7, 9 in opposite sides of the casing. The bands 6, 10 are preferably formed of steel. Printing arrangements. The setting levers 3, Fig. 4, are connected through nested tubes 11 to type-wheels 12 carrying duplicate sets of type for impressing a record strip and inserted card. Main totalizer. The main totalizer comprises a number of numeral wheels 26, Fig. 6, revoluble on a shaft 24 carried by a pair of discs 231 that receive one clockwise revolution about an axis C during each machine operation. Connected to each setting lever 3 is a chain 15, Figs 1, 6 and 8, carrying teeth 27, one or more of which are caused to enter an arc E-F, Fig. 8, by the setting movement of the associated lever. Upon the rotation of the totalizer with the discs 23<1>, pinions 25 rigid with the totalizer wheels engage the teeth 27 that are situated within the arc E-F and are rotated correspondingly to add the amount into the totalizer. Transfer mechanism. The transfer mechanism for each denomination comprises a transfer pawl 55, Fig. 6, pivotally mounted on one end of a lever 14 rockable about a stud 13 in a plate 49 carried by the shaft 24 and rotatable with the discs 23<1>. The pawl is normally held in inoperative position relatively tc a ratchet wheel 56, rigid with the associated totalizer wheel 26, by the engagement of a stud 20 on the pawl with the outer of two notches 52 in a latching arm 50. At transfer, a tooth 19 on the totalizer wheel of lower order trips the latching arm 5( and permits the pawl to rock counterclockwise into effective position relative to the ratchet wheel. As the discs 231 revolve, rollers 54 on the levers 14 successively abut stops 22 and rock the pawls towards the ratchet wheels, those pawls that are in operative position rotating their associated totalizer wheels one step. The tripped pawls are returned to normal position by the camming action of the ratchet teeth. Transaction totalizers. The machine is provided with four transaction totalizers 39, Fig. 13, selected either by a special setting lever or by the cents setting lever if the machine is only adapted to register " 0 " and " 5 " cents. In this latter case, the cents lever has a series of " 0 " positions and a series of " 5 " positions, one position in each series for each type of transaction. The setting of the lever serves vertically to position a rod 32 carrying pins 33, one of which is thus placed in register with one of a number of totalizer engaging levers, each associated with one of the transaction totalizers. During the operation of the machine, the rod 32 is rotated to shift the selected totalizer leftward into engagement with projections 35, 36 on a frame 37 that is reciprocated vertically by a cam disc 38. Actuator racks 29 situated to the left of the totalizers are provided with a set of teeth 31 for each totalizer and are lowered in proportion to the denominational amounts set up by Bowden wire connections 30 with the setting levers. As the selected totalizer rises with the frame 37, its pinions mesh with the actuators to enter the amount. At the upper limit of movement, the totalizer is disengaged and returns in operative relation to fixed stops 40 that actuate transfer mechanism of similar character to that described with reference to the main totalizer.
