Abstract

1,135,630. Rubber torsion springs. B. F. GOODRICH CO. 8 June, 1966 [11 June, 1965], No. 25579/66. Heading F2S. In a torsion spring comprising a generally cylindrical rubber bush 18 which has exposed ends and which is bonded to a cylindrical shaft 10 and to two generally semi-cylindrical shell halves 11, 12, which may be sheet steel stampings, each half shell has its internal longitudinal edges smoothly rounded off, adjacent pairs of rounded edges being separated by a space which is filled with part of the body of the rubber and adjacent portions of the shell halves being free to move towards each other apart from the restraint imposed by the body of rubber. As shown each shell 11, 12 has a key 16 which also has curved internal surfaces 17 the keys 16 being intended for reception in corresponding keyways in a supporting structure. In a modification Fig. 2, not shown, keyways 23 are formed in the shells (20, 21). In a further modification, Fig. 3, not shown, the longitudinal edges of the shell halves (24, 25) are bent outwardly to form rounded off internal edges 26 and external flanges 27 which also act as locating keys.
