Abstract

168,993. Vulcan Foundry, Ltd., and Richards, R. P. June 11, 1920. Taps.-The chasers &c. C of a tap for taperthreading are mounted in a sleeve A and engage a tapered mandrel B bolted to a sleeve e which is axially located with respect to the work by a nut e<2>. The mandrel &c. are maintained at right angles to the work by the feet f<4> of a pedestal F against which the nut e<2> is pressed by the action of the spring I, a ball thrust bearing f<3> being provided. The latter is dust-protected by a flanged retaining-ring H. The chasers C are retained by helical springs under plates c<2> screwed to the sleeve A which is rotated by a spanner &c. at a<2>, axial slots a<1> being provided for the passage of the bolt D. A modification is described to adapt the apparatus to commence the cutting operation at the small diameter of the hole.
