Class 279
CHUCKS OR SOCKETS
Class Definition:
This 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.
