Abstract
The present invention is a machine for dispensing articles, such as a vending machine, wherein the bottom article in a stack of articles is dispensed. To solve the problem of frictional resistance and excessive weight on the bottom article as it is being dispensed, the present invention provides a lifting mechanism to raise a portion of the stack of articles while the machine dispenses the bottom article. The lifting of the stack of articles above the bottom article relieves the weight of the stack from the bottom article, thereby reducing the frictional force as the machine slides the article out of a gate. In a preferred embodiment, a pair of lifting mechanisms operated by a common driving source cooperate to lift the portion of the stack of articles during the sliding operation and return the stack automatically once the bottom article has been dispensed.
