Abstract
A universal joint having a socket and a ball engaged in a bore of the socket, a pair of diametrically opposing slots in the socket wall, a socket driving pin extending through the ball and having its ends extending beyond the ball into said respective slots and being adapted to oscillate therein, and a device associated with the ball and socket to retain the ball in the socket. The pin and ball or the pin and slots are adapted for relative rotation.
Claims7
A heavy duty universal joint usable for tools in which the two ends of the tool may be misaligned, said universal joint comprising:
- a socket having a ball receiving bore, a socket ball engaged in the socket bore, a pair of diametrically opposing slots in the socket wall outwardly of the bore.
- a pin extending through a bore in the ball and having its ends therebyond extending into said respective slots and being adapted to oscillate therein,
- said ball forming a large substantially solid mass around the pin so as to provide great strength in the pin and ball engagement.
- means on said pin adjacent and generally within the external surface of said ball to positively retain said pin within the socket in the axial direction of the pin, and
- means associated with said ball and socket to retain the ball in the socket.
- said pin having two parallel flat sides adjacent each end,
- said slots having flat sides on which said flat sides on said pin slide as they oscillate.
- said flat sides of said pin being fitted in said flat sides of said slots so as to not be rotatable therein.
