Abstract
A sequencing and timing mechanism in a beverage vending machine includes a plurality of circular cams mounted on a common shaft driven by a low speed motor, and a follower is movable into engagement with each cam and actuates a corresponding switch. Freely rockably supported by each cam is a member which releasably retains a respective follower in a retracted condition and a powder feed motor is connected through each switch to a current source. A series of push buttons engage a first locking member which is releasably locked in locking position by a second locking member which, in turn, is releasably locked in a release condition by a solenoid actuated dog, the solenoid being pulse excited by a coin actuated switch. A restrictor permits the advance of only a single button which is releasably locked by the first locking member and advances a respective preselected group of follower retaining members to release position so that upon energization of the motor which rotates the cams a single revolution, a corresponding group of feed motors is energized. The cams are adjustable to effect the relative lengths of the raised and recessed portions and hence the feed motor energization intervals.
