ABSTRACT:
A multiple (infinite positions) position swivel ball mount with the swivel ball position clamp locked between two clampable base members that may be clamped toward each other between the jaws of a vise tightly on the swivel ball. Recesses are provided in each of the two clampable base members so that clamping force is exerted by the base members in opposite annular bands displaced from the opposite side center points of the swivel ball for enhanced positive clamping thereof when the clampable base members are tightened into position clamped engagement with the swivel ball. A projection from the swivel ball has an article mounting and holding fixture outer end and the two clampable base members together have an open channel permitting a greatly extended range of angled positions the swivel ball can be clamped in providing a greatly varied range of article mountings.
