Abstract Torque transmitting apparatus having two intermeshed helical gears which employs the axial thrust of the helical gears to shift the driven gear longitudinally along its axis, in a direction dependent upon the direction of rotation of the driving gear, so as to effect a clutching action between the driven gear and alternately one of two output members disposed on either side of the driven helical gear. Apparatus for synchronizing a positive engaging ratchet tooth clutch including a cam surface on one of the clutch members and a cam follower on the other clutch member to cam the moveable clutch member longitudinally toward the stationary clutch member while maintaining the ratchet teeth out of engagement one with another until the moveable clutch member has moved through its full longitudinal travel and into complete engagement with the other clutch member.
A torque-responsive transmission comprising: a. reversible drive means; b. a drive shaft; c. an elongated, helical driving gear rigidly mounted on said drive shaft; d. connecting means interconnecting said drive shaft and said drive means; e. an output shaft parallel to said drive shaft; f. helical driven gear means slidably mounted on said output shaft in reciprocably translatable engagement with said drive gear, and having opposing driving clutch members; g. driven clutch members rigidly rotatably mounted on said output shaft on opposite sides of said driven gear means and respectively adapted to be driven by the opposing driving clutch members; and h. brake means comprising a rail substantially parallel to said output shaft, an upstanding supporting member, slidably mounted on said rail, and a pair of opposing spring loaded friction blocks, mounted on said supporting member and constantly engaging opposing faces of said driven gear means, whereby a positive driving engagement is achieved between said driving gear and said driven gear in all positions of displacement of said driven gear between said opPosing driven clutch members.
