Abstract

221,455. Fornaca, G. May 20, 1924. Chucks.-In a self-centring fluid-pressure operated chuck of the kind capable of being attached to and removed from a lathe, the radially sliding jaw carriers 8 are adjusted by levers 10 pivoted at a on the chuck body and engaged by links 11 pivoted to a collar 12 connected to an axially sliding piston 3 in a cylinder 1. The cylinder is prevented from rotating by an extension 20 and is supplied with fluid from a distributing valve 17, which mav be turned to close both connections to the cylinder and thus lock the chuck. The cylinder 1 and collar 12 are rotatably secured to the chuck body and piston respectively by flanges 4, 13, ball thrust-bearings 5, 14 being interposed. The same mechanism may be used for an internal chuck.
