ABSTRACT:
A movable linkage has a surface of travel in which a generally V-shaped notch with edges is formed. A rotatable cam follower has first and second sides meeting to form a corner that fits in the notch. One of the sides of the cam follower is urged by a spring against the surface of travel of the linkage. The spring force acts in a direction transverse to one side of the notch and along the other surface of the notch. An arcuate concave relief on the first side of the cam follower adjacent to the corner is shaped to embrace one edge of the notch without such edge bottoming on the cam follower as the corner of the cam follower enters the notch.
