DEFINITION

Classification: 221/103

(under subclass 92) Devices in which each of the separate supply sources is exhausted in turn, i.e. one source is exhausted before a subsequent source is made available.

(1) Note. In this subclass are placed patents which include plural aligned sources from which the bottom article in each of the several sources is first dispensed by the movement of the bottom article of the most remote stack against the said bottom articles as it passes under the several sources in reaching the egress opening. Thereafter the rearmost source is exhausted and so on through the several sources in turn from the rearmost to the most proximate relative the egress opening.

SEE OR SEARCH THIS CLASS, SUBCLASS:

6, for similar devices including empty supply source indicating means.

11, for similar devices having means responsive to the depletion of one stack of articles to actuate a separate control for means for causing a replacement stack to replace the depleted stack. If the sensing means and the control are the same element or instrumentality, classification is in this and the indented subclasses, and especially in subclasses 108+.

112+, in which articles are dispensed from plural sources sequentially, i.e., one from the first source, one from the second, and so on.
