Abstract

172,767. Newham, L. C. Sept. 28, 1920. Coupling.-A clamping-screw for use in electric couplings &c. which does not twist the wires &c. E with which it engages, comprises a main screw A having a smaller screw B threaded into its end and a body portion D. The head of the screw B is less than the diameter of the screw A and the thread is finer. In a modification the screw A has an extension smaller in diameter and having a finer thread on which an internally-threaded cup-shaped member is fitted.
