Abstract: 1,038,543. Vending machines. NATIONAL REJECTORS Inc. April 17, 1963, No. 15031/63. Heading G4V. Credit establishing mechanism in a vending machine comprises a rotatably mounted credit member, a coin-operated lever which moves a pawl to engage the member, and a stop which halts rotation of the member after a predetermined angular displacement thereof by intercepting the pawl, the stop being rotatable to reduce friction between the stop and pawl. The apparatus is mounted in a frame comprising a plate 20 with flanges 22, 24. Totalizing mechanism is shown from both sides in Figs. 6 and 9, and comprises a toothed wheel 128 and disc 156 fixedly mounted on a sleeve 132 passing through a bush 54 in plate 20. A credit-indicating member 136, Fig. 3, rotatably mounted on bush 54, is normally rotated with disc 156 (and thus wheel 128) by a spring 168 holding pin 150 and shoulder 164 abutting. Member 136 supports a spiral array of pins 155, so that the credit established can be read out by a feeler 169, in terms of the permitted axial movement of the feeler before effecting contact with a pin. The lost motion connection 150, 164 permits the wheel 128 to advance on insertion of coins, even if the member 136 is restrained by feeler 169 during reading out, the member 136 catching up with wheel 128 when the restraint is removed. Three coin shoots for nickels, dimes, and quarters, are formed by a flanged plate 74, Fig. 8, and plates 84, 90, 96 secured together and to flange 24. Ribs 83, 87, 89, 93, 95, 99 define working slots for three stiff wire actuators, of which that for nickels is shown at 288, and that for dimes at 260 in Fig. 9. The ends 260, 296 of the actuators are bent into triangular shape and upwardly inclined, and are received in grooves 112, 114, 116, 118, 120, 122 in the coin shoots. Each actuator is pivotally mounted in ears such as 282 on a corresponding lever such as 272, the three levers being mounted on a fixed pivot 34. The pivotal mounting of actuator 288 in ears 282 prevents the actuator binding against any part of its coin shoot. The weight of an inserted coin depresses the appropriate actuator and lever, a projection 280 on the lever contacting a pin 300 on a T-shaped lever 298, so as to pivot that lever anti-clockwise (Fig. 9) on pivot 62. A spring-biased pawl 310 pivoted at 306 to lever 298 thus moves to the left (Fig. 9) (and to the right in Fig. 6), engaging a tooth 304 in wheel 128. At the same time, a shoulder on lever 298 displaces a lever 180 on pivot 34, to disengage a tooth 190 from wheel 128, which is free to rotate clockwise in Fig. 6, anticlockwise in Fig. 9, under the influence of a spring bias. The extent of movement of the wheel depends on the coin inserted. Thus if actuator 288 is depressed by a nickel, a projection 276 on lever 272 ceases to support a flange 196 on lever 194 on pivot 36, so that a further flange 198 on the lever engages and holds the wheel 128 after it has rotated half a tooth (Figs. 6 and 9). If actuator 260 is depressed by a dime, a link 271 is pulled by its lever to rotate a lever 220 on pivot 40, to offer a shoulder 222 to pawl 310, which permits wheel 128 to rotate one and a half teeth. If the remaining actuator (not shown) is depressed by a quarter, the wheel is free to rotate four and a half teeth until pawl 310 contacts an abutment 210. When the coin has passed the actuator, the latter is retained by a spring such as 258. Lever 298 and pawl 310 are returned to the position shown by spring 318, freeing tooth 304 from the wheel, and tooth 190 on lever 180 is re-engaged by spring 192, Fig. 6, this permitting the wheel to rotate another half tooth. Thus insertion of a nickel, dime, and quarter, results in total rotation of wheel 128 by one, two, and five teeth respectively. On delivery of goods or rendering of services, the wheel is reset by rotation of a toothed sector 170 engaging a gear-wheel (not shown) secured to wheel 128, the teeth on the latter and tooth 190 being shaped to permit such reverse rotation of wheel 128. The wheel 128 and teeth engaging therewith should have a low coefficient of friction. A lever 320 on pivot 60 has a weight 322 and a spring 330 bearing on a pin 182 on lever 180, so that an impact applied to the machine in the sense to tend to disengage tooth 190 on lever 180 from wheel 128, which would cause false credit to be registered, tends also to rotate lever 320 in the sense to apply spring 330 harder against pin 182, to keep tooth 190 engaged.
