Abstract

21,693. Meyer, A. Oct. 25. Drilling. - Portable compressed - air drills are secured to ships' plates, boilers, &c. by atmospheric .pressure apparatus in which the cups are exhausted by means of the drill itself. One or more of the several engines c, Fig. 1, are connected by means of a three-way cock d so that, on the remaining engines being driven, they act as pumps and exhaust the cup or cups a by means of a pipe e, Fig. 2. When a sufficient vacuum is attained, the cock is turned to close the passage d and admit compressed air to all the engines. When the drill is to be moved, the cock is turned to admit compressed air to the pipe e.
