Abstract

1411464 Digger teeth assemblies; stud and socket fastenings SOC ANON POCLAIN 10 Oct 1973 [31 Oct 1972] 47381/73 Headings E1F and E2B [Also in Division F2] In an earth-digging tooth assembly in which a digger tooth 5 is held on a support 4 by a three part cotter 13 entered into aligned bores in the tooth and the support, the cotter comprises two outer members 14, 15 separated by an intermediate resilient member 16 housed in a blind recess in one of the outer members and of a size such that it will not be completely crushed when the other outer member is caused, during insertion of the cotter into aligned bores, to enter the recess as the outer members are urged together on entering the aligned bores.
