Summary:19,623. Sandy, W. J. L., and Middleton, H. T. Sept. 3. Primary batteries.-The level of the electrolyte is varied by means of a float which can be depressed in the liquid, so that one or both of the electrodes are only submerged when it is desired to use the battery. In the construction shown, the electrodes are a perforated carbon cylinder c and a zinc block d ; the zinc is secured to a distance-piece e and cover f by means of a screw g, nut h, and washer i. The float k is connected to a rod l passing through an aperture m in the metal cover n. A collapsible tube o, connected to the float and to the cover, prevents escape of liquid if the cell is inverted. The normal height of the liquid is shown by the line p. Upon depression of the float, as indicated in dotted lines, the level rises to the line q and submerges the zinc. According to the Provisional Specification, instead of a float, bellows of the like may be used, the electrolyto being displaced by inflating the bellows.
