Abstract

1,074,834. Freewheel clutches. WEIGHBELL Ltd. June 25, 1965 [June 27, 1964], No. 26694/64. Heading F2C. A freewheel clutch for connecting coaxial driving and driven rollers 10, 12, e.g. of the teaching machine described in Specification 46338/63 comprises a nut 14, keyed to the roller 10 and threaded on a screw-threaded member 13 secured to the roller 12, having an axially projecting peg 18 engageable with a peg 17 on the roller 12 for drive in one direction of rotation, reverse rotation of the roller 10 causing the nut to move leftwards along the member 13 to disengage the pegs 17, 18. Renewed forward rotation of the roller 10 back to the angular position from which the reverse rotation commenced causes the drive to be re-established. The pitch of the screw-thread is greater than the overlap of the pegs when in driving engagement.
