Abstract
Improved blocker and jaw clutch means for shiftable change speed gearing is provided for effecting engagement of the low speed gearing of a simple transmission, or the low speed gearing of the main transmission section of a splitter type compound transmission. A transmission having an input shaft driven by a one-way prime mover, a main shaft and at least one countershaft, and including pairs of shiftable gears arranged on and cooperatively between said shafts, is provided with positive clutches, preferably spring loaded jaw clutches, for effecting connection to one of said shafts of a selected one gear of a selected one of said pairs of said gears upon the achievement of substantial synchronization between such gear and such shaft. Blockers are provided for protecting the positive clutch teeth from excessive wear during such shifting. At least one of said jaw clutches, preferably the jaw clutch for engaging the low speed pair of gears in a simple transmission, or the jaw clutch for engaging the low speed pair of gears in the main transmission section of a splitter type compound transmission, is provided with an improved blocker effective to sense only one type of nonsynchronous con…
