Abstract

220,776. Cherry, F. E., and Le Grand Sutcliff &. Gell, Ltd. July 16, 1923. Bore-hole apparatus. - In sinking bore-holes, the tool is reciprocated by a cable &c. passing round a rotary member substantially in the form of a volute and preferably comprising discs f, g between which sheaves &c. i - - i<6> are arranged. The cable is connected to, and paid out by, a winch. The Provisional Specification states also that the rotary member may be mounted eccentrically, for example about the axis of the sheave i<6>.
