Abstract

143,732. Stevens, C. H. June 10, 1919. Drilling submerged work. - A portable pneumatic drill for submerged work has the exhaust 1 controlled by a spring- loaded valve 3, so that the air pressure in the drill casing is greater than the pressure outside and prevents access of water to the drill. The valve may be near the drill, or may be at the end of a flexible tube leading from the drill. Lubrication is provided for bv a suitable device in the air-main from the compressor.
