Abstract: 309,627. Dehn, F. B., (Mills Novelty Co.). Jan. 13, 1928. Controlling stopping positions of rotating discs; prize - delivery mechanism. - In a coin-controlled vending machine of the kind having a. plurality of legend-displaying reels associated with pay-out mechanism so that checks coupons, &c., may be delivered according to the position in which the reels come to rest, means are provided for rendering compulsory manually operable means for stopping the reels so that the action of the pay-out mechanism is solely subject to the control of the operator. On the insertion of a coin and rocking of a lever 104, Fig. 1, about a pivot 103, a pawl 101 engages an arm 106 to rock a shaft 24 thereby actuating a lever 23, which engages ratchet wheels 19, to set in rotation reels 11. In the absence of a coin to form an abutment for a plunger 119 on a level- 121, a shoulder 112 on a locking lever 113 obstructs a lug 111 on the lever 104. If a coin is present, the locking lever is prevented by the lever 121 from moving into the path of the lug 111. The reels are normally held fixed by stop mechanism shown in Fig. 7 and duplicated for each reel. This mechanism comprises a star wheel 25 engaged by a head 26 of a lever 27 pivoted at 28 to a member 29 which is mounted to rock on a shaft 31. A member on the rock shaft 24 engages a cam 33 on a lateral arm 32 on the lever 27 to disengage this lever and release the reel. A bar 47, Fig. 4, is moved from the rock shaft 24 under feet 51 on the members 29 to keep the reels disengaged, the bar 47 being gradually returned by a spring under the control of a regulating vane. To render manual control compulsory, the bar 47 is prevented from fully returning until push buttons 67 are depressed by a hook 77, on a member 75 pivoted at 76, engaging with a stud 81 on the bar. The hook 77 is moved into the path of the stud 81 by the raising of the feet 51, when the bar 47 moves under bosses 71 thereon, the feet 51 acting on a portion 78 of the member 75. The push buttons act through levers 61 on links 39 connected by links 36 to the arms 32 of the members 27, each link 36 having a notch engaged by a stud 45 on the corresponding member 29, so that normally the members 27 are prevented from moving about their pivots 28. When the bosses 71 drop off the bar 47, the links 39 can be depressed by the push-buttons 67, thereby disengaging the studs 45 and allowing the levers 27 to be moved by springs 41 to stop the reels. The depression of the links 39, by acting on the tail 79 of the member 75, raises the hook 77 and allows the bar 47 to complete its return movement. The reels according to their stopping position control a series of superposed pay-out slides through vertical levers 143 which release locking levers 139 and allow the slides to be withdrawn by springs 137. The slides, however, are prevented from being withdrawn until the bar 47 has returned to its normal position so that the payout mechanism cannot operate until the buttons 67 have been actuated. A lever 49 on the pivot 48 of the bar 47 is connected to the bar by a spring 53, Fig. 4, and releases the pay-out slides, when the bar 47 is in normal position.
