Abstract

1432642 Terminal fittings BRIDON LTD 23 Aug 1974 [28 Aug 1973] 40491/73 Heading D1T An elongate terminal body 9, Fig. 1, having a bore receiving a rope or strand 1, is Characterized in that the bore has an enlarged part 10 adjacent the end at which the rope or strand enters, and a deformable member 2, 3, 5 within the enlarged part 10 of the bore, the terminal body 9 having been compressed as in Fig. 3 to cause the bore to grip the rope or strand 1 over the whole of its circumference and length in the bore so that it cannot be withdrawn from the terminal body and so that the deformable member 2, 3, 5 is held between the terminal body 9 and the strand 1 but is free to deform transversely and longitudinally. The deformable member 2, 3, 5 is stated to dissipate transverse and longitudinal vibrations transmitted along the rope or strand towards the body 9. In Figs. 1 and 3 the deformable member is a soft metal collar or ring 2 from which extends ductile metallic or resilient elastomeric rods 5 to form an open cage. A tubular plug 7 of an elastomer, e.g. epoxy resin or rubber, may be positioned between the rope or strand 1 and the rods 5. The ring 2 seals off the open end of the cavity 10 to prevent the entry of corrosives. In a modified construction the deformable member may simply be a resilient elastomeric or ductile metallic tube 17, Fig. 5, with an integral collar or ring 18, 19 at either end. The walls at the open end may be pressed over (as indicated in dotted lines). Fig. 5a (not shown) is similar to Fig. 5 except that a helical spring (24) surrounds the tube 17. In Fig. 6 (not shown) a resilient elastomeric tube surrounds the rope or strand 1 in the part 10, this tube having a collar or ring (26) sealing the open end of the part 10. In Fig. 6a (not shown) the elastomeric tube is similar to that of Fig. 6 but is thickened at its middle to form a convex plug. In Fig. 7 (not shown) the resilient elastomeric tube has a corrugated external surface. In Fig. 8 a coil spring 30 of eliptical longitudinal section is embedded in a plug 31 of resilient elastomeric material such as epoxyrubber composition, the plug 31 being in the enlarged part 10.
