DEFINITION

Classification: 279/46.1

Spring biased jaws:

(under subclass 9.1) A device wherein the gripping means is separate from the chuck body, and is (a) made of resilient or spring material, such as a tubular body slit lengthwise, or (b) biased by resilient or spring material.

(1) Note. This subclass includes a socket of elastomeric material which expands radially when compressed axially, thus gripping an object in the socket aperture.

SEE OR SEARCH THIS CLASS, SUBCLASS:

2.17, for an expanding chuck or socket having an axially moving actuator including an axially compressible element which expands radially.

43.1+, for a split resilient socket of unitary construction.
