Abstract: 477,035. Cash registers. FAIRBROTHER. H. (Neureca, Ltd.) May 18. 1936 No 14091. [Class 106 (i)] In a cash register adapted for English currency and provided with main and multipleitem totalizers, the operating means comprises a lever that for item entering is rocked downwardly and upwardly, for transferring a multiple-item total to the setting means is shifted rearwardly and then rocked, while for printing the item thus transferred and resetting the setting mechanism the lever is returned forwardly and again rocked. The invention is described as applied to a differentially-set, leveroperated machine having main and multiple-item totalizers. Items are set by adjusting knobs K positively connected to indicator drums B rotatable on a shaft 53. These drums carrv graduations extending in both directions from zero to enable the items to be set up additively or subtractively. The indicators are associated with printing-mechanism (not described) and are each provided with lateral pins 3 permanently in mesh with actuators E, F for the main totalizer C and multiple-item totalizer A respectively. An aligning bail 10 is spring-urged clockwise about its pivot 7 into contact with pinions 9, resiliently to hold the indicators in set position. In the normal position of the parts, both totalizers are engaged with their actuators so that the item is entered directly thereinto as it is set up. Now upon the depression of an operating handle 18 pivoted on the shaft 53, the totalizers are disengaged, transfers effected and the indicators and setting means restored to zero. The disengagement of the totalizers is effected by cam slots 65, 66 in the arms of the operating lever, which slots embrace the totalizer shafts 54, 55 and cause the totalizers to be shifted horizontally away from their actuators. The restoration of the setting-means is effected by a rod 12 that, upon the depression of the lever, rock pawls 11 upwardly into engagement with heart-shaped cams 61 rigid with the indicator drums. The aligning bail 10 is disabled at this time by a stud 5 on the lever, which stud wipes past the right-hand side of a projection 77 on a pawl 63, pivoted to the bail, to rock the latter counterclockwise and free the indicators. The upward return movement of the operating lever re-engages the totalizers in preparation for the next operation. Printing multiple-item totals. To take a total from the multiple-item totalizer A, the operating lever 18 is shifted to the right and then depressed. These movements, owing to the shape of cam slots 65, 66 effect the disengagement of the main totalizer while leaving the multiple-item totalizer engaged. Moreover, the left-hand parts of slots 71 in the lever now become effective to rock zeroizing levers 17 clockwise into engagement with cams 72 or transfer pins carried by the multiple-item totalizer wheels, whereby the latter are restored backwardly to zero and communicate the total to the indicators and printing mechanism. The rod 12, due to the position of the operating lever is ineffective to rock the restoring levers 11 during this operation. Thus, to restore the indicators and setting-means, it is now necessary to shift the operating lever to normal position and again depress it. Transfer mechanism. In adding operations, one of a number of zero pins 19, Fig. 6, on the totalizer wheel of lower order, becomes effective at transfer to rock a slotted member 16 clockwise, whereby a lever 15 is also rocked clockwise to interpose an abutment 73 thereof in the path of the pins 3, Fig. 1, on the wheel of next higher order. Now, upon the shifting of the totalizer to the right to disengage it from the actuators, one of the pins 3 engages the abutment 73 and rotates the wheel one step. In subtracting operations, a lever 15<1> carrying an abutment 73<1> becomes effective in place of the lever 15. The parts are restored at the end of the right-hand movement of the totalizer by means of a slotted link 78 pivoted to the member 16 and embracing the totalizer shaft. Subsequent transfers are effected by double pinions 14 with which the totalizer wheels mesh when disengaged from their actuators.
