Abstract: 4093. National Cash Register Co., [National Cash Register Co.]. Feb. 20. Receipts, checking and recording. - Relates to cash registers provided with coin displayers, autographic devices, and indicator tablets. The universal bar or key-coupler 4, Fig. 3, which overlies the rear ends of the key levers a, is connected by a link 6 to a lever 7, the hooked end 8 of which embraces an antifriction roller 9 on a stud 10, Fig. 8. The stud is secured in a slide or frame 11 mounted in guiding- grooves in the frame 18 of the coin displayer. An elastic buffer 13 is mounted on the top of the frame 11. Blocks 14 are slidably mounted on horizontal guide-bars 12 in the frame 11, and are normally held at the middle of the bars by compression springs on opposite sides of them. In each block is mounted a spring-pressed plunger 16. The case 18 contains three transparent coin-holding shutters 17 pivoted centrally, and adapted to rock from one inclined position to the opposite one between the front and back windows of the casing 18. On the right-band journal of each shutter is mounted a V-shaped frog 19, Fig. 10, provided with flanges 20 and a cam-like surface 20<a>. As the slide 11 rises, the plungers 16 bear against the frogs 19 in succession, and rock them over into the opposite positions, thus permitting all the displayed coins to pass one step downwards towards the shoot which leads to the till. On the descent of the slide, the plungers ride over the cam-surfaces 20<a>, and do not disturb the frogs. Spring-pressed locking-levers 21, Fig. 9, engage with the shoulders 20 of the frogs on the two sides alternately. A coin cannot be dropped into the casing or shoot 18 unless the cash drawer is open, the slot being normally closed by two pivoted lips controlled by the lever 31 and rod 29, Fig. 3. The lever 31 drops when the drawer is pulled forwards, and the rod 29 opens the lips. The coin discharged from the bottom shutter 17 passes down a shoot, and enters the cash drawer through the opening 36. A spring-actuated slide 37 with a pendent rear arm 38 covers the opening when the drawer is pulled forward, and presents the coin from dropping behind the drawer. The rock-shaft 39, on which the key-coupler 4 is loosely pivoted, bears arms 40 carrying antifriction rollers 41, which rest on special keys marked "paid out," "received on "account," &c., but, preferably, not on the ordinary numeral keys. The rock-shaft 39 carries also a segmental rack 42, Fig. 5, engaging with a rack 44 on a lever 45. The lever 45 is pivoted on the feed-shaft 49 of the autographic attachment. A pawl 47 on the lever 45 actuates a ratchet-wheel, and toothed feeding-wheels on the shaft 49 feed the paper by direct pressure on it as it winds up on the roll s. A compression spring holds the roll in contact with the feeding-wheels. The paper passes from the supply roller 64 over the table 65. The feed of the paper can also be effected by depressing the slide 50 and thus rocking the pawlcarrying lever 55. The key-coupler 4, Fig. 3, bears extending arms 68 adapted to lift the antifriction rollers 69 and rods 70 against the tension of springs 71. The rods 70 support a frame 72 on both sides of which are printed the words " sale not registered." This frame is lifted at the same time as the indicating-tablet which corresponds to the key depressed, and the tablet is consequently not visible until the key has been fully depressed and released, when the frame 72 descends, leaving the tablet in the elevated position. If a key is only partially depressed, the tablet will not be exposed at all. The registering-devices connected with the key levers are of known construction.
