77-TRN-456 TITLE: BLOCKED CHANGE GEAR TRANSMISSION UTILIZING RESILIENT SHIFTING MECHANISMS AND IMPROVED JAW CLUTCH ASSEMBLY THEREFOR INVENTORS: ELMER A. RICHARDS, JOHN R. VANDERVOORT, EDWARD J. BOGEMA A B S T R A C T An improved, blocked, change gear transmission utilizing at least one improved resilient jaw clutch assembly to selectively engage a selected gear to a shaft is provided. The improved jaw clutch assembly comprises two axially engageable jaw clutch members and a blocker mechanism to prevent engagement of the jaw clutch members until the jaw clutch members are rotating at a substantially synchronous speed. Preferably, one of the jaw clutch members carries axially and radially outwardly extending external clutch teeth designed for selective interengage- ment with axially and radially inwardly extending internal jaw clutch teeth carried by the other jaw clutch member. The improvement comprises providing a back-lash between the interengageable clutch teeth which is substantially greater than the back-lash normally utilized with similar clutch assemblies, said increased back-lash being in the range of five to fifteen times greater than normal back-lash and preferably about ten times greater than normal back-lash.
