Abstract: 505,339. coin-freed article-delivery apparatus. ROGERS, F. H. (Stewart & McGuire, Inc.) Aug. 29, 1938, No. 25306. [Class 27] The apparatus, which is semicircular in section as shown in Fig. 3, comprises a number of plungers 31 radially disposed with respect to a vertical shaft 51 located adjacent the back wall 92 of the apparatus, and projecting through the semicircular front wall, a corresponding number of article magazines 78, Fig. 4, being arranged in a semicircle above the plungers 31. The plungers are normally held in their inner position by springs 36. After insertion of a coin, a plunger is pulled out to allow the pile of articles in the magazine selected to drop to a shelf 84, the plunger being then released to be pulled back by its spring so that a shoulder 85, Fig. 12, on the plunger pushes out the bottom article of the pile for it to drop down a delivery shoot 22. Each plunger has a vertical fin 33 provided with a hole 34 through which balls 35 in a trough 24 contact with one another. When a selected plunger is pulled out, the balls are moved into contact and the length of the trough is such that the remaining plungers are locked. The rear wall 54<1> of a notch 54 in the withdrawn plunger coacts with a corresponding cam 53 on a sector-shaped plate 52 fixed to the lower end of the shaft 51 so as to rotate this plate and the shaft clockwise against the action of a spring 68. Depending lugs 55 on the plate 52, when this is moved, engage notches 56 in lower arms 57 of the remaining plungers to form an additional lock for them until the actuated plunger is returned to normal position. Full strokes of the plungers are ensured by pawls 42 controlled by springs 43 and engaging rack teeth 40 on the tops of the plungers. Coin action, mechanical-connection.-A coin inserted in a slot 113 passes down a testing shoot 112 to shoot arm 66 fixed to the upper end of shaft 51, the spring 68 being attached to the framework and to the portion 66. The projecting edge of the coin raises a pivoted detent 69, when the shaft 51 is rocked. The coin drops through a slot in a plate 63 to a shoot 136 leading to a money-box 137. Testing coins.-The shoot has a movable side pivoted on a rod 115 and normally held against the fixed side 112 by a spring 118, the pivoted side having a ledge on which the coin runs. Small coins are deflected by a cam on the side 112 through a hole in the pivoted side. Thickness is tested by a member 121 which can be adjusted into the shootpassage by a screw 122. Iron and nickel discs are retained by a magnet 126<1>. Weight is tested by a scale 127. A rod 130 extending upwardly from the shoot arm 66 opens the pivoted side to discharge any coins retained in the shoot 112, when the shaft 51 is rocked. A spring-controlled arm 132 detaches discs from the magnet 126<1>. Casings.-The cabinet comprises a base casting 20 to which is bolted a curtain wall 80 carrying the shelf 84 and a rearward extension 86 for preventing access to the mechanism through the delivery opening. The curved wall of the delivery shoot 22 is formed on the casting. 'The back wall 92 is bolted to the sides of the curtain wall 80 and a semicircular front cover plate 98 provided with glass panels is hinged along one side to the back wall. This is secured at its lower free edge by a hook operated by rod 104 so positioned that a top hinged cover 105 cannot be closed until the rod 104 is depressed to lock the front cover. The lid 105 overlaps-the top of the front cover 98 and is secured by a lock 107. " Empty " machines, locking.-A lug 112 on a follower 110 on each pile of articles enters a slot 111 on the corresponding plunger to prevent this from being pulled out when a magazine is empty.
