Abstract
724,729. Clamps. BALFOUR, BEATTY & CO., Ltd., and DOBSON, J. March 30, 1954 [April 29, 1953], No. 11878/53. Class 44. [Also in Group XXXVI] Spacing device for overhead cables comprises a spacer bar 10 having a clamp at each end, each clamp being securely engagable with one of the cables 17 and being connected to the bar 10 by a flexible or pivoted joint which permits limited relative movement between the clamp and the bar about vertical and horizontal axes. Each end of the bar 10 may have a portion 12 of reduced cross-section adjacent a ball 11. Each clamp comprises a pair of jaws 13, 14 connected together by screw 15 which has an unthreaded central portion with a right hand thread 21 at one side and a left hand thread 22 at the other, and one end of which is accessible through bore 24 in jaw 14. The central part of the screw may be non-circular and a slot may be formed in faces 19 of each jaw for reception of a metal locking bar 27 which bears against this part and locks the screw against rotation. Each jaw has a part-cylindrical recess 16 for the reception of cable 17 and a part spherical recess 18 for the reception of ball 11, the inner face of each jaw being cut away adjacent each recess 16 to enable the cable to be tightly gripped without the exertion of undue pressure on the ball, so that the latter is free to rotate in the socket. A recess is provided in each jaw between recess 18 and the edge of the jaw to permit limited angular movement of the bar 10 with respect to the clamp. The device may be made of aluminium.
