Abstract

410,935. Batteries. ALSTON, F. H., 1141, Coventry Road, South Yardley, Birming- ham. March 2, 1933, No. 6329. Drawings to Specification. [Class 53.] For indicating the density of accumulator acid, a single solid piece of material consisting of an arm or pointer with an integral boss or enlarged portion is mounted for angular movement on a celluloid panel and has attached thereto at a point eccentric to the fulcrum or pivot a separate controlling weight adapted to maintain the pointer in equilibrium in different angular positions according to the density of the liquid. The panel, which may be graduated, is placed over a transparent cell between the wall and plates of the accumulator.
