ABSTRACT:
A manually shiftable transmission for use in automobiles with the usual driven shaft, axially aligned with a drive shaft. The usual gears, (for example, first, second, third, and fourth gear) are present on said shafts, to transmit a drive from any one gear to said driven shaft. Four sleeves, or driven members, are mounted by splines upon the main shaft and each is slidable thereon longitudinally of the shaft to pair with a gear. Each pair of driven member-and-gear has confronting lateral faces: on each said lateral face is formed one or more dogs to engage with the corresponding dog on a respective confronting face to transmit a drive from the gear to the driven member. The driven members are adapted for sliding travel by shifting forks between a neutral position and a drive position, in which the driven dogs on the driven member engage with the driving dogs on its companion gear.
The dogs are formed with cam faces so inclined to said lateral faces that when a successive gear is engaged by its companion driven member, the dogs of an earlier engaged driven member will disengage from the driving dogs, and said cam faces will co-act to impel the driven member in sliding travel on the driven shaft to a neutral position. Thus, while accelerating, it is unnecessary to employ the shifting forks to disengage a driven member to place such driven member in neutral.
Said cam faces are so formed as to terminate outwardly from the lateral faces from which they project, in a lip. Should the brakes of a vehicle fail, said lips permit of reverse engagement to afford use of an idling engine to retard vehicle speed (as hereinafter explained in detail).
