Abstract
A cone clutch mechanism has its forward and reverse clutch gears supported by bearings mounted on the housing, with a main shaft supported by bearings mounted on the housing in the same planes as the forward and reverse gear bearings. The male cone member is biased by two springs, each encircling cam faces on the member and bearing against the forward and reverse clutch gears, respectively, to bias the cone member away from its center or neutral position.
Claims8
A clutch apparatus comprising:
- (A) a housing;
- (B) a main shaft;
- (C) first and second main bearings supporting said main shaft on said housing;
- (D) a forward gear having a clutch face on one side, said forward gear freely rotatable about said main shaft;
- (E) forward bearings supporting said forward gear on said housing, with said forward bearings in approximately the same plane as the gear teeth of said forward gear;
- (F) a reverse gear having a clutch face on one side facing said clutch face on said forward gear, said reverse gear freely rotatable about said main shaft;
- (G) reverse bearing supporting said reverse gear on said housing, with said reverse bearings in approximately the same plane as the gear teeth of said reverse gear;
- (H) a drive gear means for driving said forward and reverse gears in respectively opposite directions;
- (I) a sleeve member mounted on said main shaft between said forward and reverse gears, said sleeve member having:
- (a) a clutch face at each end, each selectively engageable with one of said clutch faces of said forward and reverse gears;
- (J) a shift means for selectively moving said sleeve member axially along said shaft to a forward or reverse drive position to engage one of said sleeve clutch faces with one of said forward or reverse gear clutch faces;
- and
- (K) a spring means for automatically forcing said sleeve member toward whichever of said drive positions said sleeve member is closest to.

A clutch apparatus comprising:
- (A) a main shaft;
- (B) a housing having first and second annular projection surrounding said main shaft;
- (C) first and second main bearings supporting said main shaft on said first and second annular projections;
- (D) a forward gear having a clutch face on one side, said forward gear freely rotatable about said main shaft;
- (E) forward bearings supporting said forward gear on said first annular projection with said forward bearings in approximately the same plane as the gear teeth of said forward gear and said first main bearing;
- (F) a reverse gear having a clutch face on one side facing said clutch face of said forward gear, said reverse gear freely rotatable about said main shaft;
- (G) reverse bearings supporting said reverse gear on said second annular projection with said reverse bearings in approximately the same plane as the gear teeth of said reverse gear and said second main bearing;
- (H) a drive gear means for driving said forward and reverse gears in respectively opposite directions;
- (I) a sleeve member mounted on said main shaft between said forward and reverse gears, said sleeve member having:
- (a) a clutch face at each end, each selectively engageable with one of said clutch faces of said forward and reverse gears;
- and
- (J) a shift means for selectively moving said sleeve member axially along said shaft to a forward or reverse drive position to engage one of said sleeve clutch faces with one of said forward or reverse gear clutch faces.
