Abstract
300,389. Kendall & Gent (1920), Ltd., and Ingham, E. M., (Representative of Ingham, J. R.). Nov. 10, 1927. Screwing; screwing die-heads.-Machines of the headstock and slide type, fitted with concentric die-heads of the type described in Specification 197,541, are provided with means for taper threading. In the case of a machine with non-rotating die-bead the ring d<1> which actuates the pivoted die carrier is driven by an adjustable two-part worm on a shaft, f<1> provided with a hand wheel for resetting and a pinion engaged by a rack e<3> pivoted to the headstock at e'. Means are provided for raising the rack from the pinion when cutting a parallel thread. When the machine has a rotary die-head the actuating ring D<1>, Fig. 5, carries pins engaging inclined slots in a sleeve operated by a yoke F<8> traversed by rack and pinion gearing driven by a rack pivoted to the work saddle at E and sliding through raising and lowering gear G<1>. Specifications 5241/83, 18988/11, and 264,329 also are referred to.
