Abstract

1,061,090. Boring earth &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N. V. July 16, 1965, No. 30319/65. Addition to 1,049,843. Heading E1F. In a roller bit according to the parent Specification the lower parts 12 of the projecting nozzles 10 are formed with parts 13 to prevent junk wedging between the lower parts and the face of the hole. The lower parts may also have projections 19 (Fig. 4, not shown) which prevent junk wedging between the adjacent rollers and the lower parts.
