Abstract: 704,337. Cash registers; transfer mechanism. ONTRE D'ETUDES M.B.A, Oct. 6, 1950. [Oct. 8, 1949], No. 24399/50. Class 106 (1) In a cash register or calculating machine, differentially-settable item wheels 24-28 (Fig. 5) are connected by nested sleeves with item indicator drums 1-7, totalizer wheels 30-35 are interspersed with the item wheels, denomination by denomination, and revolve freely on the sleeves, and the drive from the item wheels to the totalizer wheels is through the totalizer transfer mechanism. The preferred arrangement of the mechanism is shown in Fig. 1 with the transfer mechanism indicated at 40 and its connection with the totalizer at 41, whilst the system of wheels for the units order only is shown in Fig. 2. The item and totalizer wheels both bear type characters for impressing an issuing tape and are adapted for selectivly printing from either as required. A further set of type wheels 17-23 on the centre shaft 8 of the mechanism is provided for impressing an audit tape. The item wheels 24-28 mesh with gears 51 connected by sleeves 54 with pinions 53, whence further sets of gears 59 and 61 interconnected by sleeves 63 transmit the drive to the audit tape printing wheels 17. Each pinion 53 is also connected through gearing 79, 81 (see also Fig. 3) with one pinion 112 of an interconnected pair of pinions included in the transfer mechanism (Fig. 7), there being one such pair for each order and the interconnection being by means of a sleeve 113 rotatable on a common shaft 111. The other pinions 114 of the pairs drive gears 115 connected by sleeves 116 with further gears 119 in driving engagement with the totalizer wheels 30-35. The shaft 111 is mounted in a frame (not shown) rockable about the axis of the gears 115 so as to disengage the pinions 112 from the gears 81 during transfer and when resetting the totalizer. Resetting is effected by turning the shaft 111 which frictonally drives the sleeves 113 to return the pinions 112 to the zero position where they are arrested by transfer pins thereon abutting stops 136. Transfer mechanism.-Associated with each order is a plate 82 (Fig. 7) vertically slidable on slotted bars 83 and 84. When a pinion 112 passes from the " 9 " to the "0" position, its transfer pin depresses the plate 82 of the next higher order by engagement with an abutment 109 thereon. A pivoted spring-loaded latch 98 then retains the plate against the action of a return spring 100 by engagement under a lug 101 on a bar (not shown) forming part of the rockable frame mentioned above. The plates 82 are formed with gear teeth 94 in the upper edge of clearance cut-outs 93 and, when the frame is rocked to disengage the pinions 112 from their driving gears, the companion pinions 114 are engaged and driven by the gear teeth 94 of such plates 82 as are lowered, thereby to enter the transfer into the corresponding order of the totalizer. When the frame is returned, the lugs 101 engage behind and restore the pawls 98 so that the depressed plates 82 are restored by their springs 100. Consequential transfers are effected by the transfer pin rocking back a lever 108 on the next higher plate 82 upon reaching its " 9 " position, an extension 107 of the lever 108 then moving beneath a projection 110 of the lower plate 82. If then the lower plate 82 is depressed by a transfer from a still lower order, it directly acts through the parts 110 and 107 to depress the higher order plate to register a transfer in the higher order. Non-add operation and credit totalizer.-The gears 79 are mounted in a frame 78 rockable about the axis 52 of the pinions 53 by depression of a non-add key 58, this disengaging the gears 79 and 81 so that amounts entered are printed without being entered on the totalizer. The pinions 53 also drive gears 64 which are engaged by the wheels 70 of a credit totalizer, upon depression of a credit sales key (not shown). Alignment of item and totalizer wheels.-Vertically slidable in a frame 236 above the item and totalizer wheels are a pair of aligner bars 235 and 239 (Figs. 4 and 15). Both are depressible against the action of spring plates 237, 240, the bar 235 having prongs 234 which then engage the totalizer wheels, whilst the bar 239 has similar prongs 242 for engaging the item wheels as well as an extended element 243 for locking the audit tape printing wheels 17-23. The bars are selectively actuated by a series of rollers 247-250, and 255 and 256, to release the wheels as required by the operation in progress. Selecting interspersed item and total wheels for printing.-The total wheels 30-35 are of smaller diameter than the item wheels 24-29 and 36 (Fig. 5) so that the issuing tape normally receives an impression from the item wheels only. The zero characters 43 of the item wheels are carried by rings 44 (Fig. 4) actuated by springs 50 normally to retract the zero characters, so that impressions can be taken from the smaller total wheels when the retracted item wheel zeroes are set at the printing line. Zeroes in an item are printed by the item wheel aligner prongs 234 engaging raised parts 48, 49 of the rings 44 and depressing them against their springs 50 to project the zero characters located at the printing line. Reference is made to Specifications 617,346, 621,390 and 632,362 for other details of the complete machine.
