Abstract: 413,925. Coin-freed article-delivery apparatus. KADUS-WERK GES., Neustadt, Black Forest, Germany. Nov. 6, 1933, No. 30820. Convention date, Nov. 5, 1932. [Class 27.] A coin-freed vending machine wherein goods are stored in slidable or hinged receptacles which are locked by bars or sliding hooks engaging eyes on the receptacles and released by actuating a push-button after this has been released for complete movement by inserting one or more coins is characterized in that a plurality of push-button locking bars are arranged one above another at distances corresponding to the diameter of the coins. As shown, articles are stored in compartments 2, Fig. 1, arranged around a casing 1, each compartment being closed by a drawer 16 which is released after the insertion of the requisite coins by completely depressing a push-button 62 corresponding thereto so that an extension 63, Fig. 3, disengages a bolt 68 from an eye 19 on the drawer. The pushbutton is locked against complete downward movement by bars 43, 44, 45, 46, 47 which extend into recesses 51 in a plate 52 and permit of slight downward movement of the push-button. The bolt 68 is formed with an inclined surface 72 which during the descent of the bolt bears against the drawer to push it outwards so that the bolt cannot engage in the eye on its return upward movement. The plates 14 of the compartments are secured by a ring 15, Figs. 1, 3 and 6, which is locked by an extension 95, Figs, 5, 6 of a bar 93 engaging a bead on the ring. The extension is held in its locking position by the top 87 of an adjusting rod 77 bearing against a nose 92 on a bar 90 connected to the bar 93. To prevent more than one push button being depressed at the same time, ring sectors 99, Figs. 5 and 8 corresponding in number to the push-buttons and arranged in a groove in a ring 100 secured to a plate 21, abut against one another under the extensions 63 so that when one extension is introduced between two sectors no further extension can pass between them. A bar 101, Fig. 3, having notches 102 engaging round a stop 103 on each bar 43-47 is moved upwards by the inclined surface 104 when the money drawer 9 is opened so as to withdraw all the bars from the recesses 53 and permit the compartments to be refilled. In a modification only one push-button is provided which can be positioned over any desired receptacle locking bolt. The compartments 2 may be arranged in rows on each side of the casing 1 as shown in Fig. 13. Coin action, mechanical-connection and multiple-coin.-The coins fall down the shoot 28, Figs. 3, 5 and 9, and rest on a plate 34 between a spring controlled plate 39, mounted at 40 on a plate 27, and lateral lugs 55 on the locking bars 43-47. When a push-button 62 is depressed slightly the plate 39 is forced laterally by pins 57 on the plate 52 engaging cams 59 and through the coins 61, the bars 43-47 are withdrawn from the recesses 51 to unlock the push-button. A bevel 60, Fig. 9, on the plate 52 pushes the plate 34 to one side to allow the coins to fall to a shoot 38 leading to the drawer 9. To set the machine for actuation by a different number of coins, the rod 77 is replaced by one of the rods 78, 80, 82, 84, Fig. 11, which engage one or more of the stops 76 on the locking bars 43-47 to withdraw one or more of the bars from the recesses 51. Each rod is provided with a plate 86 on which is indicated the amount of money for which the machine is adjusted and is locked by a ledge 98 on the drawer 9. Testing coins.-The coin shoot 28, is curved at the top and provided with an aperture 29 through which small coins fall to a return shoot. Casings.-The casing 1, Figs. 1, 3, is mounted on a member 5 supported by balls 7 on a foot 6. A refrigerating machine, ice or a ventilating fan may be housed in the chamber 4.
