Abstract

508,217. Two-part coupling. BAILEY, N., and FOULDS, J. R. Jan. 3, 1938, No. 66.

The screw has a head shaped to fit a special key, and it may be located in a recess that can be sealed with soft metal or other material. A spring 15a may be held against the ball 11 by a screw plug 16 to' provide preliminary pressure on the ball. An insulating-shield may surround the holder.
