Antique DC Polarity-Indicator I never saw or heard of these until I found this one. It was patented in 1905 and shows polarity in a DC circuit using a liquid in a glass tube that when current is passed through it, the negative end "Glows". It has a patent date stamped on it of Oct. 25, 1905. It was available in two models, a model 3220 for battery circuits and a model 3221 for 50-600 volts. They use a liquid filled glass tube that is incased in a hard rubber type case with a connector on each end. Electrodes inside the glass tube attach to the connectors. The metal sleeve can be rotated to cover the glass windows when carried in your pocket. Manufactured by the Manhattan Electrical Supply Company (MESCO), Jersey City NJ.
