Abstract: 736,933. Coin-freed apparatus. VENDORLATOR MANUFACTURING CO. Aug. 28, 1953, No. 23837/53. Class 27. A vending machine, particularly for bottled beverages, incorporates. change-giving mechanism which rejects an inserted coin when there are insufficient change-making coins in a magazine or tube 35 and the rejection means is coupled to a pivoted finger 135 that enters the tube 35 to detect an insufficiency of change-making coins, but is withdrawn from the tube during the time that a coin is gravitating into the tube, so that it does not interfere with the fall of coins. Nickels, dime or quarters pass through a coin segregator and slug rejector and are directed to appropriate slots 30 in a disc 31 on a shaft 26 which is rotated by a handle to cause the vending and changemaking cycle. If the coin is a nickel, it is retained in the slot 30 so that, on initial rotation of the shaft 26, it cams a latch 102 out of the way of a notch 100 on a plate 99, but dimes and quarters are directed by their slots 30 to respective coin chutes 39, 40 and into respective aligned slots 53, 57 and 63, 54, 58 in slides 52, 56 and 62. Initial rotation of the shaft 26, through a cam slot 76 and linkage 85, 91 and 94, moves the slide 52 to the left; if there is a dime in the slots 53 and 57, the slide 56 is also moved to the left or if there is a quarter in the slots 63, 54 and 58, the three slides 52, 56 and 62 are moved and the movement of the slide 56, through a rod 113, lever 111 and rod 107, lifts the latch 102. Further movement of the unlatched shaft 26 will release a nickel from its slot 30 into the change coin tube 35 or, if that tube is full, into an overflow shoot. The further movement of the shaft 26 and therefore of the slide 52 will, if the slides 52 and 56 are coupled by a dime, cause a slot 59 in the slide 56 to withdraw a single nickel from the bottom of the tube 35 and deliver it through a change shoot 68. Similarly a quarter coupling all three slides will cause a further three nickels to be withdrawn by a slot 64 in the slide 62 so that change of four nickels is delivered. Whenever the slide 52 is moved to the left, a cam slope 148 on a rod 145 coupled to it engages a lever 138 on the detector finger 135 and withdraws it from the tube 35 so that the fall of a nickel into the tube will be unimpeded. On reverse rotation of the shaft 26 and return of the slide 52, a dime or quarter which may be held nipped in the appropriate slots in the slides is released through a slot 70 or 72 into a coin box and the detection finger is released so that, unless blocked by a sufficiency of coins, it can re-enter the tube 35 under the weight of parts connected to it. If the finger enters the tube, it allows a rod 131 connected to it to fall and a collar 133 on the rod is withdrawn from a spring-loaded rejecting lever 120 so that projections 124 and 125 are moved into the paths of dimes or quarters entering the segregator and cause these coins to be returned to the customer. A knob is provided on the slide 56 so that it can be reciprocated by a service-man to unload the coin tube, a pin and slot connection 88, 90 in the linkage 85, 91 allowing this without affecting the latched shaft 26.
