Abstract
Abstract A jaw clutch comprising two clutch members and a bushing with jaws at both ends, engaging each of said clutch members, one of which clutch members is mounted on the shaft with a provision for moving along the shaft axis and is constantly pressed by a resilient element against the jaw bushing so that the total axial clearance between the jaws of the bushing and those of the clutch members is smaller than the height of each clutch member jaw at the side of the resilient element. In addition, each jaw of the clutch member at the side of the resilient element has a straight portion and a portion beveled towards the face end.

Claim 1
Independent Claim
155 words
A jaw clutch comprising a shaft, a jaw bushing mounted on said shaft and adapted for rotation relative thereto, said jaw bushing having a plurality of jaws at each end thereof; a pair of clutch members each having jaws respectively adapted to selectively engage the jaws at the opposite ends of said jaw bushing, one of said clutch members being mounted on said shaft for rotation therewith and the other of said clutch members being stationary, and a resilient member biasing said one of said clutch members into engagement with said jaw bushing, each jaw of said one of said clutch members and of said bushing having a straight portion along its axial height and a beveled portion towards its free end, the total clearance between the jaws of said jaw bushing and of each of said clutch members being less than the axial height of each jaw of said one of said clutch members.
Claim 2
Dependent Claim

A jaw clutch comprising a shaft, a jaw bushing mounted on said shaft and adapted for rotation relative thereto, said jaw bushing having a plurality of jaws at each end thereof; a pair of clutch members each having jaws respectively adapted to selectively engage the jaws at the opposite ends of said jaw bushing, one of said clutch members being mounted on said shaft for rotation therewith and the other of said clutch members being stationary, and a resilient member biasing said one of said clutch members into engagement with said jaw bushing, each jaw of said one of said clutch members and of said bushing having a straight portion along its axial height and a beveled portion towards its free end, the total clearance between the jaws of said jaw bushing and of each of said clutch members being less than the axial height of each jaw of said one of said clutch members.
Claim 3
Dependent Claim
43 words
A jaw clutch as defined in claim 1 wherein the axial height of the straight portion of each of said jaws is less than said total clearance, and the total axial height of each of said jaws is greater than said total clearance.
