Abstract
Abstract A drive shaft knuckle coupler having a hub with a splined shaftadmitting bore and a series of locking detents pocketed in radial openings in the hub. The detents project into the bore to lock into an annular groove in the shaft. A cam ring is rotatable about the hub and has relieved areas alignable with the detents to permit exit of the detents from the bore to release the shaft. An outer ring with a latch is provided to releasably lock with the cam ring and locate it in release and set positions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
249 words
In a coupler for connecting a pair of shafts at least one of which has splines and a circumferential locking groove comprising: a hub with a cylindrical shaped outer surface having means for connection to the other of the shafts and having an axial bore with splines therein for meshing with the splines of said one shaft pursuant to insertion of said one shaft in said bore; detent means mounted in a radially extending opening in the hub intersecting said bore and adapted to enter into said groove for interlocking the one shaft with said hub; a cam ring rotatably mounted on said cylindrical surface and having a pocket alignable with said detent means to accommodate withdrawal of the detent means from said locking groove, said cam ring having a camming surface defining a side of the pocket sloping generally tangentially toward said cylindrical surface for engagement with the detent means for urging the same into locking position into the bore attendant to rotation of the cam ring in a predetermined camming direction; means for biasing said ring in said predetermined camming direction; a collar rotatably mounted about said cam ring and having means for releasably locking the collaR with the cam ring to accommodate rotation of both the cam ring and collar together to unlocking position of the cam ring; and means for releasably locking the cam ring with said hub and releasably maintaining said cam ring in release position with said pocket aligned with said detent means.
Claim 2
Dependent Claim
249 words
In a coupler for connecting a pair of shafts at least one of which has splines and a circumferential locking groove comprising: a hub with a cylindrical shaped outer surface having means for connection to the other of the shafts and having an axial bore with splines therein for meshing with the splines of said one shaft pursuant to insertion of said one shaft in said bore; detent means mounted in a radially extending opening in the hub intersecting said bore and adapted to enter into said groove for interlocking the one shaft with said hub; a cam ring rotatably mounted on said cylindrical surface and having a pocket alignable with said detent means to accommodate withdrawal of the detent means from said locking groove, said cam ring having a camming surface defining a side of the pocket sloping generally tangentially toward said cylindrical surface for engagement with the detent means for urging the same into locking position into the bore attendant to rotation of the cam ring in a predetermined camming direction; means for biasing said ring in said predetermined camming direction; a collar rotatably mounted about said cam ring and having means for releasably locking the collaR with the cam ring to accommodate rotation of both the cam ring and collar together to unlocking position of the cam ring; and means for releasably locking the cam ring with said hub and releasably maintaining said cam ring in release position with said pocket aligned with said detent means.
Claim 3
Dependent Claim
102 words
The invention according to claim 1 and said means for releasably holding the cam ring in release position comprising a detent pin slidably mounted in the cam ring and pursuant to rotation of the cam ring alignable with said radial opening in said hub and movable thereinto behind the detent means and slidable out of said opening by the detent means being moved outwardly from the bore during insertion of the one shaft thereinto whereby upon the groove in the one shaft being radially aligned with the detent means said detent means being urged thereinto to locking position with the one shaft.
Claim 4
Dependent Claim
42 words
The invention according to claim 1 and said means for releasably maintaining said cam ring in said release position being operably associated with said means for interlocking the collar with the cam ring and operable thereby to locking position with said hub.
Claim 5
Dependent Claim
48 words
The invention according to claim 3 and said means for releasably maintaining said cam ring in release position having an operable association with said means for releasably locking the collar with said cam means for releasing said last mentioned means attendant to release thereof of said cam ring.
Claim 6
Dependent Claim
123 words
In a drive line coupler comprising a hub having a splined bore, radial detent-mounting openings intersecting the bore, and detents in the openings extending into the bore in locking position for locking with a splined shaft inserted therein and movable out of the bore for releasing such shaft, the improvement comprising a cam ring rotatably mounted on the hub and having circumferentially displaced relieved pocket portions and close fitting locking portions facing the hub for respectively opening and closing the openings attendant to alignment of respective portions with respective openings, means for biasing the ring to position closing the openings, and detent means on the ring actuable to locking position into one of said openings upon said ring being disposed in released position.
Claim 7
Dependent Claim
123 words
In a drive line coupler comprising a hub having a splined bore, radial detent-mounting openings intersecting the bore, and detents in the openings extending into the bore in locking position for locking with a splined shaft inserted therein and movable out of the bore for releasing such shaft, the improvement comprising a cam ring rotatably mounted on the hub and having circumferentially displaced relieved pocket portions and close fitting locking portions facing the hub for respectively opening and closing the openings attendant to alignment of respective portions with respective openings, means for biasing the ring to position closing the openings, and detent means on the ring actuable to locking position into one of said openings upon said ring being disposed in released position.
Claim 8
Dependent Claim
125 words
The invention according to claim 5 and said detent means on the ring comprising a pin mounted in a radial opening in the ring and alignable with an opening in the hub, and a shield member rotatably mounted about the cam ring and having a manually actuable detent adapted to be dextrally urged inwardly and aligned with the detent means opening on the cam ring to partially enter thereinto and interlock with the cam ring to permit rotation of the shield and cam ring to a release position of the cam ring in which position the detent pin on the cam ring is aligned with one of the radial openings in the hub and partially entered thereinto whereby locking the cam ring to the hub.
