Abstract

335,282. British Dardelet Threadlock (D.D.G.) Corporation, Ltd. Dec. 13, 1928, [Convention date]. Percussive drills.-For the endwise connection of male and female members wherein each member is a right cylinder having a cross section of an archimedian spiral form the members are characterized by the provision of serrations or transverse grooves. The grooves may be closed,. or continuous in the form of helices. Instead of cylinders with parallel generatrices, the members may be formed as helicoids of extended pitch. The male member a and female member b having a section of an archimedian spiral which is completed by a short curve are shown loosely assembled and are adapted to be locked by turning the male member. The surfaces are provided with grooves and ridges which interlock and prevent axial displacement of the members. Specification 292,147, [Class 83 (iii), Metals,- Cutting], is referred to.
