Abstract: A sight mount for an archery bow embodying a bracket adapted to be mounted upon a bow. A sight support is mounted on the bracket for pivotal movement in a plane parallel to a plane extending longitudinally through the bow on which the bracket is mounted. Adjustment members are mounted on the bracket at opposite sides of the sight support with one adjustment member yieldably engaging the sight support to restrain pivotal movement thereof in one direction. A movable member is carried by the other adjustment member and is movable to selected positions toward and away from the sight support to hold the sight support at selected angular positions relative to the bracket.

Abstract: A multi-directional positioner for moving one element relative to another element wherein a socket in a housing receives a ball with a rotating fit with a portion of the ball projecting outwardly of the socket and being connected to one element and the housing being connected to the other element. An arcuate groove in the socket extends in a plane passing generally through the center of the ball and receives an electrically actuated power unit which is pivotally connected to the side of the ball. An arcuate groove in the outer surface of the ball extends in a plane passing generally through the center of the ball and perpendicular to the groove in the socket and receives an electrically actuated power unit which is pivotally connected to the adjacent portion of the housing. The power units are energized singularly and/or jointly to impart relative movement between the ball and the housing.

Abstract: A multi-directional positioner for moving one element relative to another element wherein a socket in a housing receives a ball with a rotating fit with a portion of the ball projecting outwardly of the socket and being connected to one element and the housing being connected to the other element. An arcuate groove in the socket extends in a plane passing generally through the center of the ball and receives a piston which is pivotally connected to the adjacent side of the ball. An arcuate groove in the outer surface of the ball extends in a plane passing generally through the center of the ball and perpendicular to the groove in the socket and receives a piston which is pivotally connected to the adjacent portion of the housing. Fluid is introduced under pressure selectively into the arcuate grooves in the ball and the arcuate groove in the socket to impart relative movement between the ball and the housing.
