Abstract

153,040. Hanson, J., and Dorman & Co., W. H. June 23, 1919. Drills.-A tunnel column for supporting drills and like uses comprises a cylinder u, a ram c held against rotation, a needle &c. valve b admitting fluid to the cylinder to force the ram outwards, and a nut i threaded to the ram and adapted to lock the parts in expanded position. A gripping foot h is fixed by a ball-and-socket joint to the outer end of the ram, and a further gripping-foot is fixed or hinged to the outer end of the cylinder.
