Abstract

168,158. Forrester, H. J. C., (International Earth Boring Machine Corporation). May 31, 1920. Drawings to Specification. Drilling. - Relates to a method of operating augers and consists in advancing the auger at one speed of rotation and accelerating the rotation of the auger during or after its withdrawal to expel the cuttings by centrifugal action.
