Abstract

400,357. Coin-freed article-delivery apparatus. BENKO, 1., 2, Hermanngasse, Vienna. July 4, 1932, No. 18878. Convention date, Aug. 19, 1931. [Class 27.] Articles stored in rotary drum.-Table coinfreed vending apparatus having a goods container rotatable about a vertical axis is characterized in that the coin-operated release mechanism is located above the goods container and is removable as an integral unit. The apparatus comprises a drum 3 with sector-shaped compartments, which is adapted to rotate between a hollow base 1 and a glass cover D having an opening through which the goods may be extracted. The drum is mounted on a hollow spindle projecting into the hollow base 1 and carrying a ratchet wheel 5, Fig. 4, limited to rotation in the direction of the arrow by a spring-pressed pawl 13. The wheel 5 is rotated by a spring-pressed pawl 8 on an arm 7 carried by a spindle 6 passing through the hollow spindle carrying the drum, and normally held against a stop 11 by a spring 10. When the shaft 6 is rotated, a catch 26 on the arm 7 engages a cam-projection 15 on a pivoted arm 14 and disengages the end 14a thereof from one of a series of pins s on the wheel ; the pawl 8 has now engaged a tooth of the wheel, which is thus revolved by continued movement of the arm 7, bringing the next compartment under the opening in the cover. Meanwhile the catch 26 has passed round the projection 15, and the end 14a of the arm 14 has been pulled by the spring 16 into the path of the next pin s to limit the motion of the wheel. On the return movement of the arm 7, the catch 26 rides over the projection 15. Coin action, mechanical-connection.-The coin M, Fig. 8, is inserted through a circular aperture in the cover into an aperture 17 in a disc 18 mounted beneath the cover and capable of being revolved by a handle 19, Fig. 1. The coin engages a spring-pressed pawl 21 and holds it clear of an abutment 20 on the disc which it would otherwise engage, thus permitting the disc to be turned to its full extent against the action of a spiral spring, and allowing the coin to fall through an aperture into the central part of the drum, which constitutes a coin container. The spindle on which the disc 18 is mounted carries a projection 24 which engages a projection 6a on the spindle 6. Fig. 1, thus rotating the drum.
