Abstract
A pivot assembly for mounting an operating member on a base member for pivotal movement about an axis at an optimum axial position comprising: a pivot shaft having an axis, a base member and an operating member having axially opposable first and second inner surfaces respectively, a first mounting apparatus for mounting one of the members at a fixed axial position on the pivot shaft, and a second mounting apparatus for mounting the other member on the pivot shaft for relative rotational movement, and for axial movement to a position where the first and second inner surfaces axially oppose each other with an axial space therebetween, and the other member is at the optimum axial position. The second mounting apparatus includes, a pair of compressible disk springs mounted to be in a biased condition when the other member is at the optimum axial position. The disk springs constantly tend to move the other member in one axial direction away from the optimum position. The second mounting apparatus also includes a stop which prevents movement of the other member relative to the pivot shaft in the one axial direction from the optimum position and maintains the disk springs in the biased co…
