DefinitionThis is the generic class for a chuck or a socket, per se, that is not elsewhere classified, and which includes a means for making a permanent or temporary and readily-releasable connection between a holder and an object, such as a tool, work-piece, or rod-like body, where the gripping means or seat is on or within the holder or base member. This class includes a recessed handle, a spindle, and the like, adapted to receive a tool, a tang, a rod or like body, whether permanently or in such manner as to be readily released. This class also includes a typical machine-chuck with jaws and a tool-holding socket with a detent to grip the object held against a torsional strain, a rock-drill chuck, a punch-holder, etc., where no torsional strain is applied, and in general any socketed holder and any symmetrical clamping device which may be deemed to be a receiver for positively holding an object against relative movement in at least one direction, generally in symmetrical relation concentric with the holding member, but in some instances eccentric. |
