DEFINITION

Classification: 221/175

(under the class definition) Article dispensers having means other than or in addition to supply container configuration to affirmatively cause articles from a supply container or other supply source to be formed into a single, continuous, orderly sequence, or linear arrangement which is different as to type or as to direction of orientation than the arrangement of the articles prior to the operation of said means.

(1) Note. There must be an actual formation of a stack from some substantially different arrangement to warrant classification in this and the indented subclasses. Therefore, means to merely perfect the alignment of a stack as by mere straightening are not included herein.
