Abstract

607,986. Batteries. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., WEBBER, N. W. D., and SHEPPARD, E. A. Feb. 13, 1946, No. 4507. [Class 53] [Also in Group XVIII] In an apparatus for automatically maintaining constant the level of liquid in a battery, reservoir 2, sealed at its upper end has intermediate reservoir 3 supplied with liquid through pipe 4. Supply pipe 5 has its upper end approximately level with the liquid in reservoir 3, and control pipe 6 has one end approximately level with the liquid in reservoir 3, and control pipe 6 has one end approximately level with the liquid in battery 1, the other end above the liquid in reservoir 2. A fall in liquid level in battery 1 allows air to enter space A via pipe 6, and thus liquid passes to battery via pipe 4, chamber 3 and pipe 5. Flow ceases when the liquid level rises to seal again the lower end of control pipe 6.
