Abstract: 515,856. Coin-freed article-delivery apparatus. DEHN, F. B. (Mills Novelty Co.). June 14, 1938, No. 17696. [Class 27] An apparatus for delivering bottled goods comprises a heat insulated cabinet in which the bottles are stored on trays 29, Figs. 4 and 8, hung between endless chains 31, 32 which pass over sprocket wheels 42, 46, 48, the chains being arranged as shown in Figs. 4 and 5 with several vertical runs. The sprocket wheels are mounted on frame members 38, 39 which are connected by vertical rods 40 and cross rods 41, so as to form a unit able to be removed bodily from the cabinet through side doors when desired. The chains 31, 32 are driven step-by-step after prepayment by an electric motor 49 mounted on a hinged base 51 and driving by a chain 59 and sprocket 58 a shaft 45 having a pair of chain driving sprockets thereon. The tension of the chain 59 is adjustable by a bolt 61 which adjusts the position of the motor base 51. The bottles are cooled by refrigerating means as described in Specification 505,807, [Group XIII]. The bottle in the uppermost tray 29 of the run passing round the driving sprockets on shaft 45, Fig. 7, as it descends rolls along fingers 105, which pass through slots in the tray 29, to a curved plate 113, as indicated at 114 The fingers 105 are carried by a cross-bar 106 mounted in pivoted arms 108, so that they may be turned to an inoperative position and a reserve of cooled bottles moved past the discharge position when the machine is being refilled. When the machine is filled, this reserve will have moved so that the bottles from it are the first to be delivered. The plate 113 is carried by arms 110 pivoted on a shaft 117, Figs. 7 and 8, and held in horizontal position by a spring 121. When a bottle is received by the plate 113, the latter tilts and slides a gate 124 downwardly to expose a discharge opening 94 in a plate 95. The bottle slides through the opening 94 and a shoot 93 to an outside receptacle 99. Coin action weight; coin - discharging mechanism; returning coin.-A coin 155, Fig. 13, drops down a shoot 138 and is directed between an arm 139 and a switch arm 143 to close a switch 142 and energize the motor 49. The coin is retained until the arm 139 is moved by a horizontal portion.158 thereof being attracted by an electromagnet 156, whereupon the motor is stopped. The electromagnet 156 is controlled by a mercury switch 161 which is tilted by a bottle rolling on to the plate 113. The bottle engages a strip 197, Fig. 7, connecting a pair of arms 194 which are thereby rocked to tilt the switch. The movement of the plate 113 through a link 207 holds the switch tilted until the bottle has passed through the discharge opening. A pin 168 on the arm 158 of the coin holding arm 139 normally directs the coin to position between the arms 139, 143. While the magnet 156 is energized, i.e., while the switch 161 is tilted, the pin 168 acts to return any inserted coin through a branch shoot 171 to an outside reject tray. An auxiliary mercury switch 173, Figs. 8 and 13, is provided for energizing electromagnet 156 independently of the switch 161. The switch 173 is tilted when the prescribed number 'of bottles has been delivered, by an arm on a pointer 239. which is set relatively to an indicating dial 238. A second mercury switch 179 controlling a pilot light 177, Fig. 13, is also tilted when the prescribed number of bottles have been delivered.
