Patent GB-368785-A (GB)
Abstract: 368,785. Cash registers. GLEDHILL, A. H., Trinity Works, Halifax, Yorkshire. Dec. 10, 1930, Nos. 37221/30, 17080/31, and 19378/31. [Class 106 (i).] In a key-set and operated machine the key levers are provided with graded stops to limit the excursion of spring-controlled yokes rigid with the differential actuators, subsequently restored to actuate the totalizer. Totals and sub-totals may be taken by rotating a crank shaft after unlocking by a supervisor's key. During such totaltaking the amount keys are positively locked against use. Differential actuation. The key levers A, Fig. 2, carry the graded stops a<1> to engage and limit the swing of denominational yokes a<3> linked by a spring a<4> with the restoring bail C operated by the main shaft G rotated in the usual manner by the key coupler F. Each yoke is fast with a corresponding actuating sector similar to the halfpenny actuator a<21> shown in Fig. 4. The actuators are normally locked by latches a<7> controlled by springs a<8> and removed by yokes below and rocked by the keys. To ensure quick movement of the actuators to position even when the keys are rapidly operated a spring-influenced lever t<5>, Fig. 2A, linked to the actuator yoke a<3> is adapted to be rocked by a differentiallydimensioned arm t<3> fast with a cam t rocked by a pin T on the key lever. Gearing with each actuating sector is a pinion d<x> on a com bined reading and printing indicating drum d adapted to print on an inserted slip when a hammer P is pressed by hand against the drum. Totalizer. This consists of pinions e mounted for movement into and out of mesh with the actuating sectors in a rocking frame e2 supported in a framework E. Transfer - mechanism. W h e n not engaging the actuators the totalizer pinions are in gear with transfer-sectors e<5>, urged clockwise by springs e<11> but normally restrained by latch e<9> engaging the lower of two steps e<7>, e<8> in the sectors. At transfer a trip lever e<16> is rocked clockwise and then held by a stepped latching member e<18> pivoted to the lever. When the pinions are disengaged from the actuators the displaced trip lever shifts the latch e<9> to free the transfer sector of the next higher denomination. The sectors are restored by a bail m5. Taking totals and sub-totals. Two lock barrels n, n<1>, Fig. 8, are rotated by branch and head office supervisor's keys respectively to rock a shaft n<2> one way or the other, and by means of a finger n<6>, Fig. 7, shift a gear n<8> to key it at n<10> or n<11> to its shaft f<9>, and by a connecting arm m<7> to move a notched yoke M connected with the totalizer frame to bring a particular projection m, ml above a lever j<1>, k<1> rocked by cams J, K to time the totalizer engagement for sub-total and total-taking respectively. Normally the gear n<8> is loose on its shaft and is locked in the adding position by a stationary arm engaging a notch in the gear boss, the yoke M meanwhile being situated for rendering the adding cam M effective. With the gear shifted for total or sub-total taking and upon rotation of the crank shaft o, shaft f<9> turns and through gear wheel f<8> drives the main shaft G to effect the necessary releasing and restoring movements of the actuating-mechanism. In order to prevent operation of the amount keys during sub-total or totaltaking the yoke M is coupled by a crank S<1>, Fig. 2, and vertical spindle s<3> with a comb plate s<6> to bring lugs over the ends of the key levers.
