Abstract
A noiseless ratchet drive mechanism comprises one first element with a band shell for cylindrical friction drive engagement fixed on each side. Adjacent to this first element on each side disposed a second element coaxial with the first on a shaft. This second element consists of a disc member with a plurality of integral links, and each link is connected with a second link with its one end passing through a hole in a band ring which forms the rim of the second element. To the second link is fixed an arced brake which engages the inside of the shell for friction engagement with the first element. The turning of the second element in one direction engages the first element in friction drive while the turning of the second element in the opposite direction disengages the friction engagement.
