Abstract
Abstract A clutch comprising inner and outer clutch members between which is disposed a pair of rolling members each of which is urged to a wedging position in which it prevents relative displacement or rotation of the clutch members in a corresponding one of the two possible directions of relative rotation, but allows relative rotation in the other of such direction, and means operative to displace one or other of the rolling members from its respective wedging position whereby the clutch is freed for relative displacement or rotation of the clutch members in one or other of said directions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
A clutch comprising inner and outer clutch members, at least one pair of rolling members disposed wedging position in which it prevents relative displacement or rotation of the clutch members in a corresponding one of the two possible directions of relative rotation, but allows relative rotation in the other of such directions, and means operative to displace one or other of the rolling members of each pair from respective wedging position whereby the clutch is freed for relative displacement or rotation of the clutch members in one or other of said directions, said means taking the form of a release ring having at least one projecting radial finger, the number of fingers corresponding to the number of pairs of rolling members, each finger projecting through a radial through slot or aperture in one of the clutch members for operative engagement with at least one of the rolling members.
Claim 2
Dependent Claim
148 words
A clutch comprising inner and outer clutch members, at least one pair of rolling members disposed wedging position in which it prevents relative displacement or rotation of the clutch members in a corresponding one of the two possible directions of relative rotation, but allows relative rotation in the other of such directions, and means operative to displace one or other of the rolling members of each pair from respective wedging position whereby the clutch is freed for relative displacement or rotation of the clutch members in one or other of said directions, said means taking the form of a release ring having at least one projecting radial finger, the number of fingers corresponding to the number of pairs of rolling members, each finger projecting through a radial through slot or aperture in one of the clutch members for operative engagement with at least one of the rolling members.
Claim 3
Dependent Claim
48 words
A clutch according to claim 1, wherein the number of through slots or apertures corresponds to the number of fingers and each finger is arranged for alternative engagement with two of said rolling members respectively operable to prevent relative rotation of the clutch members in said two directions.
Claim 4
Dependent Claim
13 words
A clutch according to claim 1, wherein the rolling members are cylindrical rollers.
Claim 5
Dependent Claim
29 words
A clutch according to claim 1, wherein the clutch members rotate, with the inner member in the form of a cylindrical hub and the outer member of sleevelike form.
Claim 6
Dependent Claim
62 words
A clutch according to claim 1, wherein the two rollers of each pair are urged apart to their respective wedging positions by an associated spring disposed between them, one roller of each pair being displaced against the spring loading from its wedging position to free the clutch for relative rotation of the members in a corresponding direction when said means are operative.
Claim 7
Dependent Claim
87 words
A clutch according to claim 1 comprising a plurality of pairs of rollers, wherein the arrangement is such that each two adjoining pairs of rolling members are separated by a single associated finger so that angular movement of the release ring relative to said one member from a central position, which corresponds to a fully engaged condition of the clutch, causes movement of one rolling member of each pair and thereby frees the clutch for relative movement of the inner and outer members in the corresponding direction.
Claim 8
Dependent Claim
26 words
A clutch according to claim 1, wherein each of the fingers is integrally formed with a corresponding segment of the release ring, for ease of assembly.
Claim 9
Dependent Claim
26 words
A clutch according to claim 1, wherein the release ring is arranged externally of the outer member which is formed with said radial slots or apertures.
