Title: Improvements in coin-freed delivery machines

Abstract: 291,921. S. A. N. A., Ltd., (Heller, W.). April 9, 1927. Delivery of articles stored on supports released in succession. - The apparatus comprises several sets or containers 1, Fig. 1, of pivoted trays on which the articles are stored, the trays of each set being arranged in a vertical column. A single coin-freed mechanism is provided' for releasing the trays of each set in succession, and the sets in succession. Means are provided to enable the machine to be reset and refilled without necessitating the previous release of all the travs. Each column or container 1 has three trays 2, Fig. 3, pivoted at 4 4 and provided with pins 23 working in arcuate slots 24 in the side of the container. The pins 23 rest on projections 18, Fig. 2, of pivoted latches 13 which are held against stops 211 by springs 22 to retain the trays in horizontal position. After prepayment, a shaft 44 is rocked and, by a pawl 53 and ratchet 81, rotates a shaft 35 through the space of one tooth. The shaft 35 carries toothed wheels 34, one for each container 1, each toothed wheel 34 having three teeth to actuate a pawl 15, which moves a frame 27 against the action of a spring 32. The frame has a vertical rod 25 slidable in guides 26 and carrying strikers 14, the bottom striker resting by means of a shoulder 30 on the lowest point 23 so that a nose 29 on that striker is opposite a pin 19 on the corresponding latch 13. When the frame 27 is moved by the pawl 15, the nose 29 moves the latch aside and allows the, tray to drop and deliver the article thereon down a slope 80. When the frame returns, the striker bar descends until the shoulder 30 of the next striker rests on the pin 23 of the next tray. The number of teeth on the wheels 34 correspond to the number of trays in each container, and the wheels 34 are disposed on the shaft 35 so that teeth of any one wheel are not brought into engagement with its associated pawl 15 until the last tooth of the preceeding wheel has functioned. In order to reset the machine when only a few trays have been released, the shaft 35 is slid longitudinally against the action of a spring 37 to disengage the wheels 34 from the pawls 15. It is then turned back to its initial position by a handle inserted through a hole 41, the hole being normally closed by a movable plate 43. A projection 39 from a disc 38 on the shaft engages a stop 40 to ensure the correct setting. The shaft 44 is rocked by a knob 51, a complete stroke being ensured by a toothed arm 78 engaging a pivoted spring- controlled detent 79. It carries crank arms 45, 46 having pins 47, 48 working in arcuate slots in plates 49, 50 pivoted between fixed slotted plates 59, 60. The crank 45 is connected by a link 54 with the driving pawl 53. Coin action, thrust and multiple-com.-The shaft 44 is normally prevented from rocking by the pins 47, 48 of the cranks 45, 46 entering offset portions of the arcuate slots 55 in the locking plates 49, 50. Coins inserted through slots 63 engage portions 65 of the locking plates and raise. them so that the slots 55 register with the slots 61 in the fixed plates 59, 60. Fraud, preventing.-Operation by a knife is prevented by a lever 70, a hooked end 69 of which engages a pin 68 on a locking plate. The coin, however, depresses the lever to release the pin 68. Coin-slit closing-devices; " Empty " notices, displaying. - When the last container becomes empty, plates 71 carried by arms 72, 73 on a rocking shaft 74 move across the coin slits 63. One or both of the plates may carry an " Empty " notice. The shaft 74 has an arm which rests on cross bar of the uppermost tray of the last container. When this tray is released, the shaft 74 is rocked to close the coin slits.
