Abstract
1,265,242. Chucks. O. BILZ. 7 May, 1970, No. 22019/70. Heading B3B. A quick-change chuck comprises a hollow cylindrical shank 1, a tool socket 2 adapted to be inserted into said shank 1 and to hold a tool, an adjusting nut 4 screwed upon the threaded front end of said socket for adjusting the position of the socket in the shank 1, said adjusting nut 4 having a peripheral groove 10, locking balls 6 guided in transverse bores in the shank or in a part secured to said shank, and a control sleeve surrounding and slidable along said shank for movement in a rearward direction to lock said balls 6 into said groove 10, and in a forward direction to release said balls and permit withdrawal of socket 2 from said shank 1. The chuck is characterized by the provision of a plurality of slidable elements 12 movable in longitudinal grooves 11 in the shank to transmit upward movement of the nut 4 on insertion of socket 2 into the shank 1 to the control sleeve 3 to lock the nut, and to transmit downward movement of the control sleeve 3 to the nut to release and eject the nut and socket. This arrangement allows the chuck to be operated by one hand. The elements 12 include a projection 13 that engages a spring biased sleeve 9 and an extension 14 that is engaged by the nut 4.
