Abstract

272,662. Asquith (1920), Ltd., W., and Feather, G. May 17, 1926. Chucks. - A selfaligning tool-holder for drills comprises a shank A the lower end a<1> of which, together with the part b of a toolsocket B, forms a universal joint. The socket is formed with a plain or conical shoulder b<1> against which bears a similarly shouldered sleeve C having a conical endface c engaged by the similar end of a sleeve D under the influence of a spring E whose compression is adjustable by an enclosing cap e. The arrangement is such that the spring normally maintains the parts A, B in alignment but allows the drill point to follow the lead given by a centre-punch mark, should the latter not be exactly in line with the shank A. The socket may be of any required form to hold the tool.
