455,989. Batteries. PLUMMER, R. J., and CEAG, Ltd., Queen's Road, Barnsley. May 2, 1935, No. 13077. [Class 53] An accumulator is provided above the usual cover with an additional cover a which forms or holds in place a temporary closure for the holes or vents in the filling stoppers. The terminal lugs pass through apertures b in the cover a. In the form shown in Figs. 1, 2 and 3 the cover a is applied to a battery comprising two semicylindrical cells and is formed on its under surface with two projections e which sit upon and thus close the stopper holes. Passages f may be provided in the projections e for the escape of gas, the passages having a right-angled bend and terminating at the edge of the cover a as shown at f<1> in Fig. 1. In a modification shown in Figs. 5 and 9, the projections e are formed on a member which is separate from the cover a. |
