Abstract: 22,076. Trevellian, F. H. Oct. 19. Receipts, checking and recording.-An autograph cash-register, having an invoice band and separate paper bands, one for each assistant, to summarize the totals of the invoices, comprises means whereby the totals bands are actuated by the corresponding assistant's key, which displaces a locking-plate, so that on the actuation of the main handle another locking-plate is depressed by a cam and lifts the retaining - spindle of the cash drawer, the'main handle at the same time advancing the invoice strip the length of one invoice. A plan is shown in Fig. 2 and a sectional elevation in Fig. 3. Bands of paper 27, 28, Fig. 3, are mounted on rollers 17, 18 and pass over a roller 16 ; the band 27 passes beneath a sheet of carbon paper 30 and over a plate 9, and the band 28 passes over the carbon paper. Both bands are then led under a tension roller 32, the band 28 passing out through a guide, and the band 27 passing below an opening and around a roller, being finally coiled on a receiving - roller 42 mounted on a spring-controlled arm 53. The rollers 17, 18 are mounted on conical studs 19, 20, the stud 20 being slidable in a socket against a spring and provided with a head so that it can be withdrawn. The paper bands are advanced by the main handle 43 through gearing 45, 46 and a roller 50. The tension roller 32, Fig. 7, is mounted in brackets 36 pivoted to the frame plates, the outer ends of the brackets being provided with screws 57 which bear on plates 59 and serve to adjust the pressure of the roller 32 on the roller 50. The summarizing paper bands 84, 85, Fig. 5, are mounted on rollers 76, 77, and pass over plates 68, 69 respectively, and thence to rollers 88, 89 mounted on spring - operated conical bearings 90, 91. The conical bearings, Fig. 10, have ratchetwheels 94, 95 and lugs 96 to engage slots formed in the rollers 88, 89. Upon the frame plate 64 are pivoted levers 100, 101 carrying pawls which engage the ratchet-wheels 94, 95 for moving the bands along. The lever 100 has a pin 106 engaging slots 107, 108 in locking- plates 109, 110, and a pin 111 of the lever 101 engages a slot 112 in the locking-plate 110. The locking-plates extend to and rest on rocking levers 113, 114, connected to vertical spindles 117, 118 adapted to engage brackets 121, 122. fixed to the cash drawers 123, 124. Between the locking-plates is a tumbler plate 63 with pins 133 slidable in slots 134 in the frame plate 64 and provided with springs to prevent the tumbler from being displaced. Projections 137, 138 on the locking - plates are adapted to bear against the plate 63. The keys 140, 141 are cranked to engage holes in the levers 100, 101, and pass through " L "-shaped slots in the lid of the casing, the cranks being such that the key of one assistant will not operate the drawer of any other. The main spindle 44 is provided with a cam 62 which is normally locked by a shoulder 154 of the tumbler plate 63. In operation, after the invoice has been made out on the band 28 and the total of the invoice written on the summarizing band 85 by the assistant controlling the cash drawer 123, the key 141 engaging the lever 101 is pulled forwards, the pawl 103 rotates the ratchet-wheel 95, and the paper band 85 moves to a position ready for the next entry. By this key 141 and its pin 111, the locking-plate 110 has been advanced and the projection 138 has carried the tumbler plate 63 to a position leaving the cam 62 free to rotate. If the handle is then rotated, the cam engages the shoulder 153 of the plate 109 and depresses the plate, the spindle 117 being raised and the cash drawer 123 released. The cam then strikes the shoulder 154 of the tumbler 63, bring- ing it and the locking-plates to their initial position. The spindles 117, 118 have pawls engaging bell-hammers which give warning that the drawer is opened. If the invoice strip gets out of correspondence with the opening on the top, it can be adjusted by withdrawing a socket 170, Fig. 2, provided with teeth 180 engaging teeth 179 on the sleeve of the wheel 46, which is loose on the spindle 47, thus allowing the spindle to rotate freely. The carbon-paper is held in position by a wire spring 185 lying in the groove of the bar 182, pins on the bar 182 keeping the spring in place. Two or more carbon-paper bands may be held, according to the number of copies required to be retained. In a modification, the cash-register may be provided with only one drawer and one summarizing paper band. The summarizing-band may be advauced, without moving the invoice band, by normally keeping the teeth of the socket 210, Fig. 19, out of gear with the teeth 179 of the wheel 46. The teeth are retained in engagement, when required, by a spring catch 213 lying in a groove in the shaft 47, the outward movement of the shaft being limited by the cap 215 on the end of the shaft.
