Abstract

321,353. Wragg, H. Dec. 28, 1928. Turning.-In machining or reducing the diameter of worms, screws, &c. the saddle a of a lathe is provided with a bracket c carrying a roller or the like b adapted to bear against the side of the helix e on the work and so cause the tool d to be traversed along the periphery of the work. More than one roller may be used, and in the case of a reversible lathe they are arranged on opposite sides of the helix so that the operation becomes automatic. The motion of the saddle in both directions may be assisted by weights &c. and the tool d may be replaced by a milling: cutter. The roller b is preferably arranged abovethe horizontal plane of the tool.
