Abstract
492,897. Batteries. OLDHAM & SON, Ltd., and MAIR, T. G. March 25, 1937, No. 8895. [Class 53] An accumulator container is provided with a removable window 4 secured to the exterior of the container by a resilient member 5 which engages a projecting boss 2. The window is separated from the boss 2 by a ring 3 which may be made in one piece with the window. A specific gravity indicating device such as described in Specifications 417,237, 417,238, and 442,312, [all in Group XX], may be carried by the window or mounted on a disc held between the boss 2 and ring 3. As shown in Fig. 1, the specific gravity indicator comprises an arm 6 pivoted at 7 to the window and provided at its lower end 11 with a chamber containing air. Indicating discs 8, 9, 10 are cemented to the window or the latter may be provided with a scale of specific gravities.
