Abstract

1,109,804. Lathe drivers and centres. KOVOSVIT NARODNI PODNIK. 2 June, 1966 [10 June, 1965], No. 24637/66. Heading B3B. A lathe driving centre is provided with driving dogs having gripping edges shaped and disposed so that the effective gripping length of the edge increases with increasing penetration into the face of the workpiece, the point of maximum penetration being located substantially at the centre of the gripping portion of the edge. An adjustably spring-loaded centre 2 is mounted in a body 1 by means of a sleeve insert 5 which also locates resilient members 4 of, e.g., rubber, oil, plastics material, upon which the driving dogs 3 are mounted. The gripping edges of the dogs are curved and are defined by the intersection of, e.g., a cylindrical or conical surface with a plane or by the intersection of two curved surfaces. Pins 9 retained by a ring 10 prevent rotation of the driving dogs 3 which may be mounted with their axes parallel to the axis of rotation or in an inclined position.
