Abstract

119,150. Cooper, J. Nov. 23, 1917 Tapping. - A tapping machine has a revolving and longitudinally movable tap-carrying spindle A mounted in a headstock or in adjustable bearings B and having fixed on it a clutch member D<2> through which a spacing pin d<1> slidably passes, to keep the forward driving member D and the reverse driving member D<1>, mounted loose on the spindle A, apart. The clutch members may engage frictionally, but preferably have teeth d. A spring a<2> normally keeps the forward driving members in engagement. The work may be carried in a holder c on a slidable non-rotating spindle C having an adjustable collar E which limits the movement of the spindle C, and thus causes the spindle A to be drawn forward at the end of the tapping operation so that the reverse driving members are engaged.
