Abstract

311,908. Graf, K. April 18, 1928. Locating leaks.-Leaks in gas pipes are located by means of a flexible tube b, one end of which is applied to or held in the immediate vicinity of the pipe by a reacher d while the other end is connected to a hand pump a. The pump a preferably comprises a casing having a spring-pressed diaphragm which is depressed to draw air or air mixed with escaping gas through the tube b, and an outlet or detecting tube c which is applied to the nostrils. A holder e, for insertion in the mouth as shown, may be provided on the detecting tube.
