Abstract

Abstract A one-way clutch including an outer member containing a bore surrounding a spaced inner member with a full complement of rollers in side-to-side engagement located around the inner member between the two members. One or more control members may be spaced between the rollers to urge the rollers in a given rotary direction against wedging ramps provided on the surfaces of one of the members to engage the clutch for driving purposes.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 134 words
A one-way clutch including: a first member containing an internal bore; a second member located within said bore, the entire external periphery of the second member being spaced from the interior of said bore; a plurality of equal length rollers and at least one resilient member in side-by-side engagement and together completely surrounding the second member and located around said second member between said members and the circumferential force applied to one of the engaged rollers in a rotary direction by said at least one resilient member will be transmitted through the rollers throught the engagement between said rollers; and one of said members carrying a series of wedging surfaces for cooperating with the rollers to wedge and lock said rollers between said members when said rollers are urged in a given rotary direction.
Claim 2
Dependent Claim 134 words
A one-way clutch including: a first member containing an internal bore; a second member located within said bore, the entire external periphery of the second member being spaced from the interior of said bore; a plurality of equal length rollers and at least one resilient member in side-by-side engagement and together completely surrounding the second member and located around said second member between said members and the circumferential force applied to one of the engaged rollers in a rotary direction by said at least one resilient member will be transmitted through the rollers throught the engagement between said rollers; and one of said members carrying a series of wedging surfaces for cooperating with the rollers to wedge and lock said rollers between said members when said rollers are urged in a given rotary direction.
Claim 3
Dependent Claim 19 words
The one-way clutch of claim 1 wherein: said wedging surfaces are located on said first member within its bore.
Claim 4
Dependent Claim 19 words
The one-way clutch of claim 1 wherein: said wedging surfaces are located on the periphery of said second member.
Claim 5
Dependent Claim 13 words
The one-way clutch of claim 1 wherein: said resilient member is a spring.
Claim 6
Dependent Claim 19 words
The one-way clutch of claim 4 wherein: said spring is anchored to said one member carrying said wedging surfaces.
Claim 7
Dependent Claim 56 words
The one-way clutch of claim 4 wherein: said resilient member is a resilient roller spring that is larger than said rollers and is located between two of said rollers, said roller spring urging said engaging rollers in said given rotary direction by reacting against an abutment surface mounted on said one member between said wedging surfaces.
