DEFINITION

Classification: 254/333

Having pressure element spaced from drum to confine cable thereagainst:

(under subclass 266) Apparatus including an element spaced from the drum's periphery just far enough to allow the cable to barely pass between the drum and element at their nearest point; the cable at this point is slightly compressed, or has a compressive force placed on it, by the drum and element, and consequently is caused to advance by the contact of the cable with the driven drum's periphery.

SEE OR SEARCH THIS CLASS, SUBCLASS:

216, for implements or apparatus for tensioning flexible material or for extracting stumps or poles including a rotatably driven drum and a pressure element spaced therefrom for confining a cable or the material against its surface.
