F. VAN DE WIEL STOPPER FOR CLOSING THE CONTAINERS OF ELECTRIC ACCUMULATORS [WI @7750? L Jail 7a] Patente June 19, 1923.

FERNAND VAN DE WIEL, OF PARIS, FRANCE, ASSIGNOE '10 COHPAGSIIE GENERALE IDELECTRICITE, OF PARIS,

STOPEB FOB CLOSING THE CONTAINERS OF ELECTRIC ACCUM ULATORS.

. Application filed October 25, 1920, Serial No. 419,531. .Renewed March 30,1923.

To all'whomz't may concern:

Be it known that I, FE-RNAND VAN DE VVIEL, a subject of the King of Belgium, residing at Paris, France, have invented new and useful Improvements in Stoppers for Closing the Containers of Electric Accumulators, of which the following is aspecification.

The present invention relatcs'toimprovements relating to stoppers for closing the containers of electric accumulators.

In electric accumulators of which the containers are provided with a cover, a stopper which permits the'escape of the gas is necessary. 7

According to the present invention such stoppers are so constructed as. to provide the following combinati'onof features viz: that the gases charged with liquid particles are constrained by one or more vertical baffles to traverse a circuitous path between their entrance into the stopper and their escape into the surrounding air; and further the gases enter and leave the stopper at points which are at a higher level than those through which liquid particles carried in suspension by the gas respectively return to the vessel or re-enter the stopper.

In the accompanying drawing Figures 1 and 3 are sectional and plan views-respectively, of the improved stopper;

Figures 2 and 4 are sectional and .plan views, respectively, of a modification of the stopper;

Figures 5 and 6 are sectionaland plan views, respectively, of a further modification of the stopper.-

Referrin to Fi s. 1-4 the gases charged with 'liqui partic es enter the stopper by openings A where the battle 3 causes them to traverse a circuitous course during which they leave on the walls C, D, E, F the liquid particles with which they are charged.

These'particles collect in the bottom of the stopper and re-enter the contalner through holes G, the presence .of the liquid in the pass through openings L in t annular channel between the walls of the baflie and the stopper enter the latter by the open'm A, whence they escape by the apertures the liquid particles collecting in the hollow I and returning to the container by the opening J and the openings at the bottom of the stop' er.

ti le bafiles cou d be 0 the stopper.

Having now particularly described and It is obvious that mulplaced in'the interior ascertained. the nature of my said invention and in what manner the same is to be per.- formed, I declare that what I claim is:

A stopper for an electric accumulator comprising a body having gas inlet ports. a separate liquid outlet port at the bottom of the body arranged at a lower level than the gas inlet ports, gas outlet'ports'at the upper part of the body, a liquid inlet port located at a lower level than said gas outlet ports, and bafliesinterposed between'the gasinlet ports and also interposedbetween the gas and liquid outlet ports arranged to cause the outgoing gases to traverse a circuitous path,

said baflle being also arranged to intercept the direct fiow of gas from the liquid outlet port to the gas outlet port.

'In testimony whereof I have signed my name to this specification 1 FERNAND VAN or: WIEL.
