Abstract
A chuck is formed with a generally cylindrical body formed with a bore at a forward end thereof. A fixed clamp segment and a movable clamp segment are located in radial opposition in the bore . A pair of ribs are formed on the fixed segment and extend radially inward. A single rib is formed on the movable segment and extends radially inward. The ribs and cooperate to clamp a shank therebetween in a clamping mode. A sleeve is positioned about the body and is movable axially relative thereto. A camming section formed on an interior wall of the sleeve is captured between a head of a pin and a detent ring to latch the sleeve in an unclamped mode. When the shank is inserted into the bore , the forward end of the shank engages the pin to move the head against the camming section which, in turn, moves the section past the detent ring. In this manner, the sleeve is unlatched and moved forward to compress a plurality of rollers against the fixed segment and the movable segment to place the sleeve in a clamped mode, whereby the shank is clamped.
