ABSTRACT:
A mechanism which is operable as a clutch or vibration damper comprises two rotatable members. One of the members is mounted coaxially within the other member and has a radial extension which extends into a chamber formed in the other member. Particulate drive transmitting medium is contained in the chamber. Relative rotation between the two members is permitted up to a certain limit velocity, above which the drive transmitting medium, under the action of centrifugal force, provides sufficient frictional contact between the two members as to permit drive to be transmitted between the two members. A passage extends radially outwardly from the chamber. A screen across the passage permits only particles smaller than the particles of drive transmitting medium to escape therethrough out of the chamber in use of the mechanism.
