Abstract

320,809. Cammell, Laird, & Co., Ltd., and Archer, J. Dec. 5, 1928. Tools; tool-holders. - In boring, turning, planing and like tools of the kind having a detachable cutter with tapered sides secured to a holder by a central pin or stud, the sides of the cutter taper inwards from both ends to form a waist which is forced by wedge action of the central pin against an undercut shoulder on the holder. The cutter 10 having a cutting edge 11 is provided with a waist 13 which is forced into engagement with the undercut shoulder 15 of the holder 14 by means of a pin having a cylindrical portion 17 coacting with a cylindrical hole in the cutter and a tapered portion 18 coacting with a similar hole in the holder. The holes in the cutter and holder are out of line to enable the pin to force the surfaces 13, 16 together and clearance is provided at 15 and 21. The pin 17, 18 is preferably circular in cross-section but may be of other section and is preferably a good fit in the cutter-hole, the surfaces 15, 13 may be in contact, and the pin may be tapered on its whole length, the holes in the cutter and holder being then both parallel or tapered. The cutter may be circular in section as shown at-the right-hand end of Figs. 1 and 2 or of square or other section as shown at the left-hand end. When circular, the base portion below the waist is given a polygonal form with flat sides 20 for co-operation with the shoulder 15 and when polygonal the base may differ in shape from the cutting edge 11. When the cutter is arranged below the holder, for reverse cutting, the pin is still inserted from the top and is oppositely tapered to prevent its falling out. To enable the cutter to be used after repeated grindings the corners 22 are removed to provide clearance for the work, the shoulder 15 is of less height than the cutter and the wajst 13 is arranged as close to the base 20 of the cutter as possible. According to the Provisional Specification the central hole in the cutter may be tapered.
