Abstract

Abstract A uni-directional overload release clutch which when installed with one side thereof connected to a rotary power input element and with its other side connected to a rotary power output element provides a torque limited left hand drive and a solid right hand drive; and which upon installation in an end for end turned over position provides a torque limited right hand drive and a solid left hand drive. In either case the clutch may be reengaged by forward rotation of the output element or by backward rotation of the input element through not more than a full turn.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 69 words
An overload release clutch comprising radially inner and outer clutch members defining an annular space therebetween, a rotor within said space; detent means operatively interposed between said rotor and one of said clutch members; and double throw lock-up means operatively associated with said inner and outer clutch members and with said rotor whereby said rotor may be coupled selectively with either said inner or with said outer clutch member.
Claim 2
Dependent Claim 69 words
An overload release clutch comprising radially inner and outer clutch members defining an annular space therebetween, a rotor within said space; detent means operatively interposed between said rotor and one of said clutch members; and double throw lock-up means operatively associated with said inner and outer clutch members and with said rotor whereby said rotor may be coupled selectively with either said inner or with said outer clutch member.
Claim 3
Dependent Claim 27 words
An overload release clutch as set forth in claim 1 and further comprising torque transmitting lost motion connecting means between said rotor and said outer clutch member.
Claim 4
Dependent Claim 26 words
An overload release clutch as set forth in claim 1 and further comprising one-way drive transmitting means operatively interposed between said rotor and inner clutch member.
Claim 5
Dependent Claim 40 words
An overload release clutch as set forth in claim 1 and further comprising torque transmitting lost motion connecting means between said rotor and said outer clutch member, and one-way drive transmitting means between said rotor and said inner clutch member.
Claim 6
Dependent Claim 52 words
An overload release clutch as set forth in claim 1, wherein said double throw lock-up means comprise a radially reciprocable shuttle key on said rotor and seating recesses for said shuttle key in the outer periphery of said inner clutch member and in the inner periphery of said outer clutch member, respectively.
Claim 7
Dependent Claim 46 words
An overload release clutch as set forth in claim 1, wherein said outer clutch member comprises a peripheral wall and opposite end walls straddling said rotor, and wherein said ball detent means are operatively interposed between said rotor and at least one of said end walls.
Claim 8
Dependent Claim 110 words
An overload release clutch as set forth in claim 6, wherein said rotor has a circumferential series of axial bores, wherein each of said end walls has a circumferential series of ball pockets adapted to register, respectively with said axial rotor bores, and wherein said detEnt means comprise a series of coil springs housed, respectively, in said rotor bores, and a pair of balls at the axially opposite ends of each of said coil springs, said balls being urged, respectively, in axially opposite directions against said end plates and cooperable with said ball pockets to thereby establish a releasable torque transmitting connection between said rotor and said outer clutch member.
Claim 9
Dependent Claim 20 words
An overload release clutch as set forth in claim 7 and further comprising removable filler means for said ball pockets.
Claim 10
Dependent Claim 59 words
An overload release clutch as set forth in claim 6 and further comprising a circumferential series of drift pins reciprocably seated in one of said end walls, and means operatively associated with said outer clutch member and rotor for reciprocating said studs in response to rotary displacement of said outer clutch member relative to said rotor in opposite directions.
