Abstract

1,021,999. Earth digging teeth. R. L. LAUNDER and E. L. LAUNDER. Oct. 29, 1964 [Dec. 20, 1963], No. 44254/64. Heading E1F. A digging tooth 1 for earth excavating and moving equipment is at the rear provided with rearwardly tapering limbs 3 capable of being deflected laterally to a limited extent and terminating in lateral enlargements 7. This construction allows of a satisfactory securing of the tooth in or on in a male or female relationship with a holder 8 having cam surfaces 5 for causing flexing of the limbs and locking surfaces 19, 20 at the ends of the cam surfaces 3 for appropriate engagement with the enlargements 7 of the, preferably, flat, chisel-pointed tooth.
