Abstract: 374,469. Cash registers. WERTS, C. J., 36, Camborne Avenue, West Ealing, London. March 10, 1931, No. 7417. [Class 106 (i).] The item is set up by differential manual movement of endless chains or belts controlling the indicating drums D and, on their release and return, actuating the totalizer. The chains are provided with alternating finger-pieces 1 between which can be seen the numerals to which they refer. The operator places his finger on the desired piece and draws it down, together with the chain, until his finger strikes a trigger 8 and rocks a pivoted locking-bar 10 which is then latched down to hold the chainwheel 6 against return movement. The whole of the item having been thus set up a fingerlever 34 is operated to rock a spindle 25 and by means of arms 35 to displace the latches 17 to allow the bars 10 to rise from locking engagement with the chain-wheels 6. Under the action of coiled springs 37 the chains therefore return to normal position and the movements are transmitted through clutches 47, 50 to numeral drums 62. The clutch parts are normally separated, a forked member 42, for shifting the slidable part 47, holding the other part 50 against rotation. When however the locking-bar is depressed a projection 44 from it rocks the member 42 to elease the part 50 and force the part 47 into driving engagement therewith. The clutch parts are then maintained in engagement by a spring-controlled lever pivoted on the chain-wheel 6 and adapted when the part 47 is slid to the right to interpose itself between the part and the wheel. At the end of the restoring movement of the chain the lever strikes a stationary lug and allows the clutch part under the action of spring 63 to return to open position. For transactions other than cash receipts the clutches may be rendered inoperative by endwise displacement of a bar 70 carrying the locking-bars 10 to prevent their operation of the clutches. The rotations of the clutch parts 50 are transmitted to the numeral drums 62 through sprocket gearing and rat-trap clutches 61 and transfer from farthings to pence takes place through a sleeve 86 rocked by transfer teeth 84 and operating the higher drum through a pawl and ratchet wheel. For transfer to shillings a sleeve 93 rocked by the pence drum carries a lug 98, Fig. 8, serving to free a latch 100 from a pin 99 to allow a pawl 94 carried by an arm 96 to engage the shilling ratchet wheel 95. When the lever 34 is rocked therefore to allow the amount set up to be entered, the arm 96 mounted on the shaft 97 of this lever is operated to effect the transfer thus prepared in the previous operation of the machine. The clutches 61 are maintained in engagement by arms 111 the shillings one of which is adapted to be rocked to free the clutch for transfer purposes when the shaft 97 is operated. Both arms 111 may be rocked clear by means of a hand-lever 115 for zeroizing, so that rocking of the latter frees the clutches for independent rotation of the clutch parts. In a modified arrangement for registering halfpennies without the use of the setting chain, a pitman 131, Fig. 9, is pivoted to a hand-lever 130 and connected to an indicating drum F by a pin and #-shaped slot 134. If the lever is pulled forward the drum is turned to present the ¢d. indicator at 138 but in the subsequent operation of the lever 34 a lug 140 depresses the pitman to allow the drum to return to normal and the pin to engage the other limb of the slot 134. On the next entry of a halfpenny therefore the rearward movement of the hand-lever rocks the drum clockwise to bring another ¢d. indication into view and through a pawl 144 to add one to the pence drum, the pitman and drum being subsequently restored, due to the action of lug 140, to the position shown in Fig. 9. Printing of items on a strip may be effected by type-wheels 71, Fig. 1, driven by the chains and rocked forward for impression when the lever 34 is operated. The drawer normally released when the locking-bars 10 are operated may also be freed by use of a No-Sale key 80.
