An adjustment device is provided having a block with two longitudinal bores therethrough joined by a slot. A movable member, having a threaded hole therethrough, is slidingly disposed in one bore, and a movable ball and a fixed member, having a curvilinear surface, are disposed in the other. A set screw, having a conical point, is inserted through the slot and screwed through the movable member so that the conical point engages both the fixed member and the movable ball. Further movement of the set screw forces the cone point between the fixed and movable balls, thus causing the movable ball to move away from the fixed ball.
