Abstract

1,104,310. Boring earth &c. SHELL INTERNATIONALE RESEARCH MATTSCHAPPIJ N.V. 7 Oct., 1966, No. 44942/66. Addition to 1,049,843. Heading E1F. In a roller bit according to the parent Specification, the outflow end 9 of each nozzle 8 is angled to direct the flow of liquid towards those cutting teeth of the outer row of teeth of an adjacent cutting element 7. The axis of the end 9 lies within the range 120 to 150 degrees with respect to the axis of nozzle 8.
