Abstract
An incremental drive mechanism for a switch operating timing cam is disclosed. The mechanism includes a camshaft having a radially extending cam and a cooperating slide which is adapted to reciprocate along a rectilinear path. The slide has first and second cam surfaces which are engaged during a major portion of a single revolution of the camshaft to reciprocate the slide in a positive manner. The slide has a cantilever spring arm which carries a pawl tooth at its end to engage successive teeth provided on the periphery of a switch operating cam drum or disc.
