Abstract: 358,918. Coin-freed article delivery apparatus. BENJAMIN, H. S., 1005, Parkway East, Utica, New York, U.S.A. July 14, 1930, No. 21267. [Class 27.] Articles stored in piles.-Articles are delivered -in succession from a series of vertical magazines 3, Fig. 1, by recessed rollers 5, Fig. 2, mounted on parallel shafts 10 and geared together by wheels 11 for simultaneous rotation. One wheel 11 is geared by wheels 20, 21 to a shaft 15 bearing a ratchet wheel 19, Fig. 6, driven by a pawl 25 which is carried by an arm 22 actuated through a pin-andslot connection 23, 24 by a vertical, reciprocating plate 12. The plate 12 is controlled by a spring 38 and is reciprocated by a rotary cam 35 engaging pins 36, 37. 'the cam being mounted on a sleeve 34 loose on a shaft 29, which is rotated by a button 31. A head 78, Fig. 5,.on the shaft 29 has pivoted to it a dog 80 in engagement with a lug 81 on the adjacent end of the sleeve 34. In the absence of a coin, a pin 88 on a lever 82 is moved into the path of a lug 89 on the dog, thereby disconnecting it from the lug 81 and preventing the sleeve 34 from being rotated. The lever 82 has a lug 84 which, in the presence of a coin, travels in an inner groove in a head 86 carried by the sleeve 34. If a coin is not inserted, the lug 84 travels in an outer peripheral groove in the head 86 and disconnects the dog 80. At the end of the travel in the inner groove of the lug 84, the pin 88 engages a tail 90 of the dog 80 to release this, the sleeve 34 being then returned to its initial position by a spring 91. A full stroke of the shaft 29 is ensured by a pawl 95, 96 engaging a ratchet 94 on the head 78, the pawl being brought into engagement by a latch 98 actuated by a stop 101 on the head and being released at the end of the stroke by a second stop 97. Coin action, weight and with stationary coin forming abutment.-A coin inserted in a slot 77, Fig. 2, after passing testing devices drops down a shoot 44, Fig. 6, where it tilts a lever 50 to depress a rod 42 which disengages a latch 45 from a lever 46 and raises a stop 39 out of the path of a lug 38a on the plate 12. A bent end 47 of the lever 46 is moved into the shoot 44 by a spring 49 and forms a support for the coin. The coin resting on the stop 47 prevents inward movement of a plunger 55 connected to the lever 82, so that the lug 84 on this lever is . constrained to move in the inner groove of the head 86 as described above. Testing coins ; fraud, preventing.-If a washer or too thin a coin passes to the stop 47, the consequent movement of the plunger 55 prevents actuation of the machine. Before reaching the shoot 44, the coin passes through a shoot 103, Fig. 8, formed by a fixed wall 104 and a pivoted wall 105. Coins of too small a diameter are deflected through an aperture 107 in the wall 105 by a rib 108 on the wall 104. Too thin coins drop through a gap 109 between the walls. Light discs fail to move aside a pivoted stop 110. Iron or nickel discs are stopped by a magnet 114. The wall 105 is moved to clear the shoot by a lug 113 on a bar 111 engaging a stud 112 on the wall. At the same time a sweep 115 actuated by the bar 111 clears discs from the poles of the magnet. The rejected coins &c. drop through a shoot 117 to the delivery to the article delivery cup of the machine. The bar 111 is actuated by a bar 72 carrying a slotted plate 73, Fig. 2, which is provided with pins 75 engaged by a cam 74 on the shaft 29. The cam 74 moves the bar 72 downwardly against the action of a spring 76 each time the button 31 is operated. A depending weighted bar 119 pivoted at 120 allows only a very limited forward turning of the shaft 29 when no coin is inserted. The lower end of this bar is in the path of a shoulder 123 on the head 86 and is turned aside by a coin engaging a lateral extension 121 disposed opposite the end of the plunger 55 and entering the shoot 44. A slotted bracket 124 supports the bar 119 and prevents it from being bent by forcible turning of the head 86. " Empty " machines, locking ; returning coin.- When the magazines 3 are becoming empty, a spring-controlled pin on a following weight 56 in one magazine, the shortest, passes through a slot 58 in the magazine wall and actuates a lever 59 to release a detent 61 from a spring-controlled lever 63. The lever 63 carries at its lower end a blade 65 which enters the coin shoot 44 to deflect coins therefrom to a return shoot 66. The lever 63 is held, however, by a pivoted dog 71 on the bar 72 until the next actuation of the machine after its release. The dog 71 resets the lever 63, when the magazines are refilled, and the operator turns the button 31 after manually releasing the locking mechanism.
