DEFINITION

Classification: 254/199

PORTABLE IMPLEMENTS OR APPARATUS FOR TENSIONING FLEXIBLE MATERIAL OR FOR EXTRACTING STUMPS OR POLES:

(under the class definition) Implements or apparatus for (a) contacting and applying a pulling force to at least a portion of a flexible member, (e.g., cable, fabric, strand, wire, etc.), to place the member in a stressed (e.g., stretched, tensioned, etc.) condition or (b) dislodging an article in the nature of a stump or pole (including a fence post, tree, etc.), from its embedment in the ground, the implement or apparatus being detachable from the member or article and movable to a different location after use.

(1) Note. The implements or apparatus of this subclass are intended to be separable from the article being stressed or dislodged and are not intended to remain with, or become a component of, the article after it has been stressed or dislodged.

(2) Note. The dislodging implements or apparatus of this subclass are not intended to move the article more than an insignificant distance subsequent to its extraction from its original location.

(3) Note. If permanent deformation of the strand, etc., occurs, it is incidental to, rather than the intended purpose of, the tensioning.

109, and 110+ for leather-stretching implements of special application to lasting.

24, Buckles, Buttons, Clasps, etc.,

19+, 32+ or 68+ for a tightener which either (a) is a permanent component of, (i.e., permanently attached thereto or formed therewith) a belt or strap, or (b) is a separable component of a belt or strap which remains therewith while the belt or strap is in use and is ordinarily detached

therefrom during periods of nonuse.

26, Textiles: Cloth Finishing,

51+, and 71+ for devices other than stationary frames for stretching or pulling cloth.

38, Textiles: Ironing or Smoothing,

15.8, for skid chain-applying tools; and subclass 9.3 for hose clamp appliers, and subclasses 300+ and 487 for a hand held clamp adapted to grip a flexible article and by which a direct pull may be given to tension or manipulate the flexible article.

100, Presses,

32, for binding apparatus in the nature of a stationary machine not otherwise provided for, including means by which a binder encircles material and is tensioned to increase its tightness about the material.
