Abstract

557,153. Centring work for turning. NORBURY, E. Oct. 10, 1942, No. 14242. [Class 83 (iii)] A lathe fitting for drilling centres in work pieces comprises mountings for a conical drill 26 and a small clearance drill 28 which may be selectively positioned in alignment with the work axis. A pivot pin 13 accommodates a head 14 having sockets 23 in which the drill 24 and a holder for the drill 28 are secured by grub screws. The head is secured by a handle 19 screwing on a thread 21 and its positions are determined by a 90 degree slot 18 coacting with a pin 17 on the body 11 or by spring plungers. The head is urged to one extreme position by a spring 30 while tightening of the handle 19 tends to move the head to its other extreme position.
