ABSTRACT:
The apparatus is for selectively preventing the motion of one part relative to another part to which it is pivotally connected. There is a plate with a planform of a segment of a circle attached to one part, the plate being perpendicular to the axis of the pivoted connection and the center of the segment coincident with the center of the pivot. A clamping apparatus is mounted on the other part and comprises a backstop on one side of the plate and a pointed part positioned on the other side of the plate opposite from the backstop and mounted on a mechanism by which a point of the pointed part can be pressed against the plate, in turn pressing the plate against the backstop to lock the connection. The working surface of the backstop is a set screw adjustable in the stop to adjust the clearance between the stop and the point of the pointed part. The pointed part has a plurality of points and can be attached to its supporting mechanism with any one of the plurality of points in position to engage the plate.
