Abstract

1,068,144. Chucks. CENTRE DE RECHERCHES DE PONT-A-MOUSSON. Feb. 3, 1966 [March 25, 1965], No. 4746/66. Heading B3B. A clamping chuck for a lathe comprises fluid pressure operated radially movable jaws (9) (Fig. 1, not shown) and similarly operated axially movable jaws (22), the said axially movable jaws (22) being movable along an axis inclined to the axis of the chuck so that they converge as they move away from the front face of the chuck. In the embodiment described a brake drum (T) is held in the chuck by firstly centring the bore (a) on a centring member (6) fixed to the front face of the chuck, clamping the axially movable jaws (22) on to the inner flange of the drum and then clamping the radially movable jaws (9), on to the external periphery of the drum. The jaws (9) and (22) may be arranged to have replaceable end noses for selecting appropriate jaw parts for different workpieces.
