Abstract

534,135. Lathe centres and tailstocks. HERBERT, Ltd., A., and HERBERT, Sir A. Jan. 1, 1940, No. 14. [Class 83 (iii)] A lathe tailstock comprises a centre 11 mounted in a casing 12 movable axially in the tailstock body 21 and having an enlarged hollow portion within which is slidably keyed a nut 22 coacting with an axially fixed but rotatable screw 26. A coil spring 25 is located between the nut and a shoulder in the casing and in operation the hand wheel is first turned to compress the spring solid and is then turned back until a pre-determined axial thrust indicated by a dial 30 is exerted on the work which can expand in operation against the spring pressure. The centre bearings include a rear needle bearing 16 and taper roller and thrust ball bearings 17, 18 at the front, adjustment being effected by nuts 19.
