DEFINITION

Classification: 175/369

(under subclass 331) Apparatus in which the rolling cutter element is journaled on an axle or pin, supported at one end only in cantilever fashion and provided with a particular means to rotatably secure the rolling cutter element with respect to the axle or pin.

(1) Note. The securing means need not be releasable and may be intended to permanently secure the cutter to the stub axle (e.g., "snap connections"). Patents which merely recite that the cutter is "releasable" have been classified on the basis of other claimed features and cross-referenced into this subclass when appropriate.

368, for releasable means to secure a rolling cutter to a detachable stub axle.
