DEFINITION
Classification: 494/51
Plural driven means:
(under subclass 50) Apparatus wherein two or more driven means, at least two of which means are independent of one another in one or more characteristics, are present.
(1) Note. The following are considered to exemplify, but are not intended to limit, the interpretation of "independent": (a) a reciprocating means and a rotating means, (b) a plurality of rotating means, at least one being driven at a different speed, or in a different direction, than at least one other thereof, (c) a plurality of rotating means, at least one having a different axis of rotation than at least one other thereof, or (d) a plurality of rotating means driven by a common shaft, at least one serving to impart movement (1) in a different direction than another (e.g., a conveying screw segment having a left-handed thread and another segment having a right-handed thread) or (2) of a different nature than another (e.g., conveying by one, stirring by another).
