Abstract: 18,943. Piscicelli, Count R. T. Sept. 2. Receipts, checking and recording; counting -apparatus.-A cash register indicates to the purchaser and cashier the amount of each sale, prints it on a ticket and also on a record slip in the column corresponding to the department, and sums and indicates the departmental receipts and number of sales, and likewise the totals of these. The machine is described for a decimal coinage and for four departments, and is operated by an external handle, two revolutions of which effect the necessary single rotation of the shaft 37, Fig. 3. The four rows 22, Fig. 7, of nine keys each, enabling price -units from 0 to 9999 to be recorded, are arranged o the cylindrical front of the machine. Immediately above the bevelled end of each key are recesses whereby the perforated plate 30 of the pivoted sector 28, held by the spring 32, can lock a depressed key as shown, and prevent depression of other keys. Pressure of the lever 36 causes the arm 34 to move the plate 30, and allow a wrongly-set key to return, and a cam on the shaft 37 ensures the sector remaining in the position shown during the indicating and printing processes, so that other keys cannot be accidentally set, finally depressing the sector slightly to release the keys. Engaging with one sector is a grooved cam 41 on the shaft 37 which prevents the plate 30 from being moved by any lever 36 during operation, all the levers being keyed to the shaft 33. The external lever 13, Fig. 28, pivoted to the shaft 29, is placed in a position assigned to the department for which a sale is to be registered, and thus, by means of bevel wheels and linkwork, the summing-apparatus and printing-roll are adjusted. The lever also has two four-toothed segmental racks, one of which takes a detent out of gear with a ratchet-wheel on the shaft 37 when the lever is in one of the four positions, and the other is locked by a tooth on a bell crank lever operated by a cam on the shaft 37, unless that shaft is in the inactive position. The movement of the cam 43 on the shaft 37 allows the spring-controlled piece 44, Fig. 3, to turn until the end 46 is stopped by a depressed key. The partial summing drums 59, Fig. 9, are arranged on the same shaft 62 with the four drums pertaining to each row of keys adjacent, and are borne by a carriage 48, now so placed by the lever 13 that when the cam 63 moves it will free the proper arm 50, the rod 53 will fall to one of the steps of the piece 44, and the segmental rack effect proportionate motion of the pinion 56, which drives its number-drum 59 by a pawl and ratchet. Pinions 61, 65 and the sleeve 66 on a countershaft 68 move a tooth 67 engaging with a ten-toothed star-wheel 60 on the next highest number-drum of the same department to effect the carry-over, the cams 63 being displaced to secure successive actuation. Two additional carry-over drums at the higher end are provided for each department. Similar total-indicating apparatus, with but one drum for each row, gives the sum of the four department-totals, the operating sector 71 being rotated by the spring 73 as the rod 53 falls. The heads of these rods form a continuous track for the passage of the projection 74 when the carriage moves, brackets 69 and shields 70 guiding the arms 50. Fig. 12 shows the device adopted for setting the total-indicating drums to zero by turning the shafts from the outside. Eight drums 115, Fig. 3, four each for the cashier and purchaser, are provided for showing the amount of a sale, the members of each pair being constrained to move together by external teeth and pinions on countershafts 124, 125. As the shaft 37 turns, the cams 123 and rods 120 effect disengagement of the spring-held racks 117 from the pinions 116, enabling internal spiral springs to set each drum to zero. The racks reengage when the piece 44 stops, and register the value on the return stroke. Link-work moved by the arm 126 rotates an arm round the shaft of the pinions 116 carrying screens to obscure the drums 115 during operation. Five numerators 14, 15, 16, 17, 18, Fig. 19, give the number of sales. The tappet 142 is rotated by the shaft 37 but travels with the carriage 48 to select the proper actuating-lever 139, the arm 141 of the total numerator being always lifted. Stepped pawls and tentoothed ratchet-wheels are used to revolve the number-drums, every tenth notch being of greater depth to effect the carry-on. There are spring- detents 145, lever-returning springs, and zerosetting apparatus of the type described, the spindles being connected by gearing so that one only has to be turned. When each piece 44 is at the end of its first movement, sleeves on the shaft 29, and sectors 150, 151 thereon bearing the figures 0 to 9 in type, have set the value of the purchase along the lines M N and P Q, and against them will be the reference letter for the department, set by sectors moved by the lever 13. As the paper comes from the roll 153, it passes between cylinders 154, 155, of which the former is driven by gearing from the shaft 37 and bears two ribs 159 to feed intermittently ticket-lengths forwards, and also a pin 160 to hold the web when the machine is at rest. Of the seven internal discs which project through an opening, four 161, Fig. 32, print the number of the ticket, one, 162, the month, and two 163, the day thereof, spur-wheels 166, 167 and setting-heads 165, 164 being provided and a zerosetting head for the number wheels, which are similar to the numerators and are actuated by a pin 169, which runs in a ring 170, Fig. 35, and is attached to a lever so as to produce oscillations of an arm on the shaft 174, carrying driving-pawls. By partial rotation of the eccentrically-mounted roller 156, the two rollers are separated, an impression prevented, and the linkwork shown, Fig. 35, centres the ring 170 and thereby stops the number wheels. The tooth 197 on the cylinder 154 and the bell-crauk lever 196 cause the inkers 192, 193 to pass into position over the effective types, when they are lightly pressed by the platens 157, 200, of which the former is carried on a sliding-block 190 actuated by a cam on the shaft 37. This platen afterwards makes a longer impression stroke, when the knife 158 cuts the web and the ticket falls into the rest 28. The carriage 89 derives motion from the department-lever 13, and bears the shaft 198, with the paper roll 199, the arm 203 carrying the platen 200, and the shaft 202 for a ratchet-held sleeve 201, into such a position that the amount may be printed on the web in the proper column, the two strokes of the platen being effected by projections 211, 212 on the roller 154 lifting the rod 208 and arm 203, the ratchet feeding on the down-strokes. As the shaft 37 rotates, the tappet 223, Fig. 39, strikes the arm 225 of the hammer, and causes the bell 226 to sound. By contact of the same tappet with the pin 224 on the lever 216, the catch 219 is lifted, and the cash drawer 4 forced out on its rollers by the spring 215 till it meets the stop 227. The spring 218 then causes the catch to fall, and the hook 228 engages the ratchet-wheel 221 and locks the shaft 37. A lever 229 provides for opening the drawer independently.
