Abstract

978,314. Bowden mechanisms. BOWDEN (ENGINEERS) Ltd. July 26, 1962 [April 27, 1961], No. 15313/61. Heading F2K. A lubricant seal between a Bowden cable 1 and the end of its conduit 2 is formed by a plastics bush 7, e.g. of nylon or P.T.F.E., having a part-spherical surface 8 rotatably held in an end fitting 3 of the conduit, the bush 7 being preformed into sealing engagement with the helical strands of the cable 1 so that it acts as a nut and is rotated as the cable moves. As shown, the bush 7 has a cylindrical portion 12 and is held in a metallic fitting 3 by swaging the end 6 thereof. In a modification the plastics bush comprises a ball located between an outer flange on an end fitting and a washer seating on a shoulder therein. In manufacture the bush is deformed into engagement with the cable 1 preferably without the use of heat, and it subsequently recovers sufficiently to act as a nut. The conduit 2 comprises one or more coils of wire of circular, triangular or trapezoidal section and has a P.V.C. or other plastics sheath 2a. The interstices of the cable 1 are preferably initially sealed to prevent the ingress of moisture by immersing the cable in liquid wax. Specification 880,260 is referred to.
