Abstract
An expansible shaft in which an axially-movable cam forces a core engager radially outward into engagement with a surrounding core. A cam follower attached to the core engager slidingly engages a cam surface of the cam, a recessed slot is parallel to the cam surface, and one end of a cross-bore in the cam follower overlies and follows the slot as the cam follower slides along the cam surface. A second bore perpendicularly intersects the cross-bore. A first member is mounted in and forms a slip-fit with the cross-bore, a second member is mounted in the second bore, and the length of the first member is such that a portion of it projects into the slot when the second member is within the bore intersection, but the entire first member fits within the cross-bore when the second member is withdrawn from the bore intersection.
