Abstract
A shielded universal joint having a pivot head defining a primary axis. The pivot head has a ball and a neck. The ball has a longitudinal slot. The slot has a throat at the center of the ball. The imperfect socket head is provided having a socket and a pin. The socket defines a secondary axis. The socket has a cavity concentric with the secondary axis. The cavity closely receives the ball. The socket has a continuous margin. The pin is joined to the socket in spaced relation to the margin. The pin extends through the passage. The pin defines a first pivot axis extending longitudinally through the pin. The pin and the throat define a second pivot axis extending through the throat and the pin perpendicularly to the first pivot axis. The socket head is simultaneously pivotal relative to the ball about both of the pivot axes.
