DEFINITION

Classification: 221/224

(under subclass 208) Devices having two or more discharge assistants or having at least one discharge assistant combined with article handling means which apply force to cause nongravity movement of the articles.

(1) Note. Plural similar instrumentalities which are actuated by a common power source or linkage to concurrently engage one article and apply a discharging force to that article are considered to be a single discharge assistant and are excluded from this and the indented subclasses and are classified in appropriate subclasses below. Similarly, unitary or substantially unitary devices having pluralities of article engaging and discharge assisting surfaces (i.e., endless belt carried discharge assistants as in subclass 253, segregating chamber structures having plural chambers as in subclasses 263+, etc.) in which the surfaces carry successive articles through the same path to the outlet are excluded and placed in other appropriate classifications as indicated.

157+, and 171+, for dispensing and orienting combinations including means for handling the articles subsequent to segregation from the source of supply.

187, for devices in which an article is dispensed in response to motion of a supply container, means being provided to subsequently move the dispensed article in a direction normal to that of the movement of said supply container.

290+, for dispensers having means to release articles, as by gravity, and to subsequently manipulate such articles. SEE OR SEARCH CLASS
