DEFINITION

Classification: 254/213

Including rotatably driven drum for engaging either material or force transmitting cable:

(under subclass 199) Implements or apparatus including a driven drum which rotates about an axis fixed relative to another portion of the implement or apparatus, and which winds about its axis, or otherwise engages and pulls, either (1) the flexible member or (2) a cable which is (a) adapted to be connected to, or (b) attached to a portion of the implement or apparatus which is adapted to be connected to, the flexible member or article.

(1) Note. The term "cable" is used herein to designate a flexible element, such as rope, chain, wire or a flat band.

(2) Note. The other portion of the implement or apparatus

may be no more than a clamp, hook, etc.

(3) Note. The term "drum" is used in this and the indented subclasses to designate a rotatable structure, (e.g., capstan, driven pulley, driven sprocket wheel, gipsy, spindle, spool, wildcat, winding drum, windlass, etc.), which is caused to turn about an axis of rotation by a drive source and which has a perimeter for contacting and pulling on the cable or flexible member, whereby a driving force is transmitted from the source, by way of either the drum and cable, or the drum, to the flexible member or the article.
