Abstract
Abstract A timing circuit provides an auxiliary source of energization for a vend relay of a multiselection coin operated vending machine wherein dispensing from one of a plurality of columns is controlled by selective energization of a dispensing solenoid. The operating coil of a selected dispensing solenoid is energized upon actuation of a selection switch adapted to be connected in circuit with a pair of normally open contacts of the vend relay which contacts are closed upon energization thereof. A timing capacitor is connected in parallel with the operating coil of the vend relay. The charging circuit of the capacitor is through the hold circuit for the vend relay. The capacitor, upon operation of a vend select switch, which causes energization of a corresponding vend solenoid and deenergization of the vend relay hold circuit, discharges through the operating coil of the vend relay to thereby cause the vend relay to remain energized for a fixed period after the select switch has been actuated.
