DEFINITION

Classification: 221/208

(under the class definition) Article dispensers having means to affirmatively segregate, separate or move the articles from a supply source toward a point of egress.

(1) Note. The weight of the articles, alone, is not considered as an affirmative means for this and the indented subclasses. The application of a force other than gravity tending to move an article or articles relative to other articles to effect a segregation or separation is necessary.

(2) Note. Where an element applying a force to segregate articles has an agitating function as an incident thereof and has combined therewith some other discharge assisting means classification is in subclasses 200+. See also the note to the definition of subclass 200.

(3) Note. Included in this group (see subclass 246 as an exception to the requirement that an affirmative force be applied to the article to effect segregation) are devices in which the sliding movement of the cover of a supply receptacle effects segregation of an article from the remainder of the supply, but does not necessarily affirmatively move any of the the articles.

(4) Note. See "General Statement Of Class Subject Matter" C subsection (4) of the class definition for a discussion of discharge assisting means as provided for in this class.
