Abstract: An auxiliary can dispensing unit (30) for use in vending machine (2) comprises an inclined track (32). Pivotal control member (62) at the discharge end (34) of track (32) dispenses a single can (42) at a time. Pivotal control member (62) is actuated by a cam (78) and connecting rod (98) which are releasably secured to the output shaft (20) of a motor. The inclined track (32) is releasably contained in dispensing channel (10) of vending machine (2) and is meant to replace the helical coil (14) normally used therein.

Abstract: A helical coil vending machine includes a housing having a plurality of shelves thereon. Each shelf includes a plurality of elongated helical coils of a first size received in dispensing channels having a nominal width. This invention relates to an auxiliary dispensing unit which can be received in selected ones of the dispensing channels. The auxiliary dispensing unit includes a replacable insert member or trough receivable in the dispensing channel to decrease its cross-sectional width. The first sized coil in this channel is then replaced by a second and smaller coil which is received inside the insert member. The auxiliary dispensing unit is suited for receiving relatively thin articles such as gum and mint packages therebetween for vending such articles using a helical coil mechanism.

Abstract: In a dispensing machine of a helical coil type having a plurality of shelves which each contain at least one elongated helical dispensing coil, an insert member is received inside the convolutions of selected coils. Each insert member comprises a plastic rail member having a bracket at one end. The bracket loosely and nonrotatably journals the insert member about the shank of the output shaft of the motor for the coil. The insert member extends forwardly through the coil to a position between the last and next to last convolutions of the coil. The insert member is free floating relative to the coil by virtue of its mounting and rides on the inner surfaces of the lowermost portions of the convolutions of the coil. Rotation of the coil imparts a rocking movement to the insert member. Thus, the insert member supports the products received in the coil above the shelf surface and further agitates these products to prevent their sticking to the insert member.
