Abstract
884,055. Screw-cutting lathes. BATAAFSE PETROLEUM MAATSCHAPPIJ N.V. June 23, 1958 [June 25, 1957; April 18, 1958], No. 27391/60. Divided out of 883,864. Class 83 (3). Apparatus for cutting screw threads of varying pitch and diameter comprises a tool 21 carried on a cross-slide 20 the movement of which to cut a tapered thread is provided by an inclined guide-bar 23. The cross-slide is mounted on a saddle 18 moved by a cam 27 rotated in unison with the headstock spindle. The cam profile is such as to give a non-uniform pitch to the thread and a rapid return. Specifications 786,652, 799,028 and 806,553 also are referred to.
