"Screenlight" Gauge Glass Illuminator, patents pending, fitting on Dewrance Boiler Water Gauge
This attachment for a boiler water gauge is used to overcome the difficulty frequently experienced in a bad light of reading the level of the water, and is a modification of the familiar gauge glass with the red stripe painted on the back, the object being to use the glass, where it is filled with water, as a lens.
