Abstract

128,191. Poyet, M. J. June 12, 1918, [Convention date]. Chucks.-In an internal chuck of the type in which the work may be mounted or dismounted while the machine is running, the jaw-operating cone g is carried by a rod e to which is attached a head f having oppositely-coned surfaces which are acted on alternately during the opposite movements of a sliding internally-coned collar c through balls i, i<2>, and i<3>, i<5> and rounded pins i<1>, i<4>, or through pins or balls only. The chuck b<1> is formed on the end of the mandrel b which is screwed to the mandrel a. The balls and pins are. mounted in inclined slots in the mandrel a, which slots may be parallel to or at any angle to each other. A hard washer k is provided to receive the pressure of the ball i<3>, when pressing the rod e outwards and the ball i<5> is pushed out of the bore against the stop collar d when the rod' moves inwards.
