Abstract
882,653. Pull-wire systems for mines. DAVIS & SON (DERBY) Ltd., JOHN, and DAVIS, W. B. July 23, 1959 [April 29, 1958], No. 13492/58. Class 78 (5). A pulley block (Fig. 1) intended for carrying the pull-wire of the signalling system of Specification 781,881, has an insulating pulley 21A carried by a clip 15, 16. The clip is pivotally carried at 13 by plate 10 adapted at 11 to be carried by a support, and is separated from the pulley by an insulating bracket 17, 18. The bracket is made in two identical inter-dowelled parts 17 and 18 so that one plastic mould will suffice. In this way the pull-wire is surrounded by insulating material. Similarly, the pull-wire may be carried by a clip 15, 16 (Fig. 4) which is pivoted at 13, is secured at 28 and is separated from the pullwire by insulator 25 made in two identical interengaging parts. Specification 880,866 also is referred to.
