Abstract

363,216. Screwing. DEUTSCHE WERKZEUG-UND MASCHINENFABRIK KIRCHHOFF & CO., 6, Hainstrasse, Bliedinghausen, Remscheid, Germany. Feb. 10, 1931, No. 4182. Convention date, Feb. 10, 1930. [Class 83 (iii).] Screwing-dies and die-heads ; stocks and dies.- In a taper-threading screwing die-head the chasers b are radially adjustable in the body a by means of a rotary cam-plate d. An extension e of the body is screwed at f with the same pitch as that to be produced on the work, to engage a work-support h. An exchangeable bush g serves as a work guide and is secured to the support h by screws k which also secure the work. A ring l is rotatable on the support but is slidably keyed at l<1>, Fig. 4, to the extension e and carries a lug m in which a block n is adjustably secured by a screw n<1>. An inclined cam-bar d<1> formed integral with the cam-plate d slides through the block n and thereby causes the cam-plate to be rotated during screwing for producing a taper thread. Adjustment of the block n in the lug m varies the diameter of the thread produced, a scale m<1> being provided for facilitating the adjustment. Parallel threads may be cut by leaving the block n loose on the lug m or the screws k loose on the work. The ring l is attached to the support h by means of a semicircular dove-tailed portion thereon engaging an annular recess h<1> in the support, and the body a may be rotated by a ratchet or by the usual handles.
