Abstract

129,920. Richards Thread Milling Machine Co., and Richards, G. Jan. 2,1919. Milling screws; milling-cutters.-For hobbing screw-threads on taper surfaces, the axis of a parallel hob is inclined to the axis of rotation of the work, or a taper-hob may be employed mounted to rotate on an axis parallel to the work axis. The work A is held in a rotatable workholder B and is acted on bv two parallel hobs F having their axes inclined to the work axis and mounted on a slide D for feeding. The slide D is carried by a slide D<2> pivoted at H and carrying gearing N, O, P for rotating the cutter spindle from the main shaft L, which also rotates the work-carrier. One hob F may have an extension cutter to cut the chase G in a socket fitting.
