Abstract

1390858 Friction ratchets F R RAMSTROM AB 7 July 1972 [16 July 1971] 31880/72 Heading F2Q In a friction ratchet arrangement wedges 7 and 8 selectively engage a groove 2 of a wheel 1 to drive this wheel in one direction or the other in response to movement of the piston-rod of an operating cylinder 4. A lever 3 is attached to the end of the piston-rod and carries the wedges 7 and 8, pivoted on spindles 5 and 6 respectively, the wedges being biased by a spring 11 into contact with a pin 9 which has flats bevelled on it so that it moves the wedges into or out of their respective operating positions on being rotated. In the position shown wedge 7 moves the wheel 1 counterclockwise as the rod is extended. A piston 4 may drive more than one edge assembly, which may have a common pin 9. Both wedges may be simultaneously engageable.
