Blocked change gear transmission and improved blocker and jaw clutch assembly therefor

摘要

An improved, blocked, change gear transmission having an input shaft normally driven by a one-way prime mover and an output shaft normally connected to a driven device is provided. The improved blocked transmission utilizes at least one improved blocker and jaw clutch assembly which allows engagement of a selected ratio gear under static conditions, i.e., when the driven device is at rest and the blocked transmission is in neutral.
