1,149,336. Guiding cables. MORSE CONTROLS Inc. 18 March, 1968 [26 Oct., 1967], No. 13033/68. Heading B8B. [Also in Division F2] A conduit for use in a system for transmitting motion by balanced cables 13A, 13B, comprises opposed parallel ducts 34 connected by a web 28, each longitudinal duct 34 having a longitudinal cleft 36 through the outer wall 31 thereof to facilitate axial twisting of the conduit. A coupling 35 is provided for joining two conduits in abutting relationship, the coupling being similarly shaped to the conduit and including a screw and nut 54, 63 for clamping the coupling to each conduit via an aperture in the web 28 thereof. The ends of the conduit may be received in terminal blocks where the cables leave the conduit to be received on a drive or driven drum, in elbow members where the direction of the cables are changed, or in lateral take-off members where one cable passes straight through and the other is taken off to a further drum. Twisting of the conduit about its longitudinal axis to facilitate alignment of the ducts 34 with appropriate cable pulleys in the elbow and take-off members, is restricted by the walls 29, 30 of the conduit being engageable by key-plates adjacent the said pulleys. The key-plates are extended within the elbow and take-off members to guide the cables from the ducts to the appropriate pulleys. Instead of using a terminal block between the elbow or take-off member and the pulley, a minimum friction collar may be provided at the exit from the elbow or take-off member. |
