Abstract

264,077. Cuthill, J., and Oil Well Engineering Co., Ltd. July 28, 1925. Rod joints; spigot-and-socket screwed joints.-In a screwed joint for connecting drill or fishing tools to drill pipes or rods, the two parts a, b of the joint are formed with butting shoulders g, h, inclined at the same pitch angle as the connecting threads e, f and stepped to form coacting stop surfaces i, j, so that the two parts thereof cannot become wedged when screwed together.
