Patent
·
OSTI ID:5215643
An indicating device for a storage battery comprises a barlike body which is transparent, inserted through, and held on the upper wall of the electrolytic vessel of a storage battery, has a pointed lower end, and is immersed in the electrolyte in the storage battery, and an indicating member which is disposed in the electrolyte near the lower end of the bar-like body, rotatable around a horizontal axis, has its specific gravity correlated with that of the electrolyte, and has its center of buoyancy deviated from the rotative axis thereof so that the indicating member is rotated as it sinks and floats according as the specific gravity of the electrolyte varies. The arrangement is such that, when the indicating member is seen through the transparent barlike body from above the storage battery, the indicating member, for example, selectively moves into and out of a visible range so that the manner of indication is changed according to the specific gravity of the electrolyte. 42 figures.
