Abstract

171,437. Blacker, W. April 11, 1921. Screwing.-In hollow-die screwing machines adapted to be driven by hand or power, and in which the work is clamped in a carriage and fed towards the die, the carriage comprises two blocks d which slide on parallel guide-rods e secured to the headstock b. The faces n of the vice fit into dovetailed grooves in the jaws i, which are mounted on transverse rods k, @ connecting the carriage blocks d. The carriage is operated by a hand-lever g which is slotted to receive the right and left-hand threaded vicescrew j. The hand drive for the spindle c is direct, or through a pinion mounted on one of the rods e.
