Abstract

139,672. Ivey, P. D., and Salisbury, A. J. April 22, 1919. Hydrometers.-The lid of an electric battery cell is provided with a tube 3 for guiding the stem of a hydrometer 5, the upper part of which is enclosed in a glass dome having an indicating line 2<1> marked on its surface. A removable rubber or vulcanite cover 4 can be secured over the dome 2.
