Abstract
366,267. Chucks ; lathe and like drivers. CRAVEN BROS. (MANCHESTER), Ltd. and HOWES, S. R., Vauxhall Works, Reddish, near Stockport. Jan. 21, 1931, No. 2008. [Class 83 (iii).] In a lathe driver or chuck for railway carriage or wagon wheels, slides b radially movable in a driving ring c are adjusted by a rotatable cam ring f having a cam surface m<1> for each slide. L-shaped pieces m secured to the slides engage cam slots n to effect a positive withdrawal. Wedge-shaped gripping jaws a are slidable circumferentially along inclined surfaces a<1> of the slides to increase the grip if the work o tends to slip and are normally retained in the retracted positions by springs. The ring c is attached to a face-plate d which also carries a central sleeve g with projections h, the action being such that as the cam ring f is rotated by a tommy bar &c. to release the work, the projections h engage projections i on the cam ring to centralize the jaws a and ensure the withdrawal of each jaw, but on gripping the work the projections ride away from each other as shown in the Figure to allow the jaws and cam ring to float and grip the work evenly. The movement of the jaws along the inclined surfaces a<1> is limited to prevent undue pressure being exerted on the wheel, or the slides b may grip the work directly. The cam ring may be rotated by a motor through worm gearing.
