Complete Specification Left, 29th Aug., 1890-Accepted, 25th Oct., 1890
PROVISIONAL SPECIFICATION.
Improved Means for the Prevention of Polarization in Electric
Batteries.
We HENRY BADCOCK, of 101 High Street, Chemist, WILLIAM GRUNSELL, Quay,
Coal Merchant, and ARCHIBALD WALKER, Quarter Master Sergeant, Royal Engineers,
of 25 Southampton Buildings, all of Lymington, County of Southampton, do hereby
declare the nature of this invention to be as follows:-
According to this invention polarization in electric batteries is prevented by
imparting a continuous or periodical motion or disturbance to the liquid, the invention
being primarily intended to be used with bichromate of potash batteries. The
disturbance of the liquid can be effected in numerous ways; the one which we have
found to give the best results is to arrange a tank slightly above the cells and to cause
liquid from the tank to run into the cells to overflow them, the overflow liquid being
caught in a bottom tank and carried or pumped back to the high tank in any suitable
manner. Or the upper tank and lower tank can be so arranged in a stand supported
by a central pivot or bearing as to admit of the bottom tank when full being lifted up
and the top tank brought down to receive the overflow.
Dated this 29th day of November 1889.

COMPLETE SPECIFICATION.
Improved Means for the Prevention of Polarization in Electric
Batteries.
We HENRY BADCOCK of 101 High Street, Chemist, WILLIAM GRUNSELL, Quay,
Coal Merchant, and ARCHIBALD WALKER, 25 Southampton Buildings, Quarter Master
Sergeant, Royal Engineers, all of Lymington, County of Southampton, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained, in and by the following
statement:
According to this invention polarization in electric batteries is prevented by
imparting a continuous or periodical motion or disturbance to the liquid, the invention
being intended to be used in single fluid batteries such as those in which the exciting
fluid is bichromate of potash.
To properly explain how we carry this into practice reference should be had to the
accompanying drawings.
Figure 1-is side elevation of our arrangement.
Figure 2-plan.
Figure 3-plan of bottom part of Figure 1.
A are the cells preferably formed of carbon supported on glass strips B attached
to a conveniently arranged support C; D is a tank to hold the bichromate of
potash, arranged to feed all the cells, continuously by turning the tap E, the feed
passing through a short arm of tubing F into a cross tube G from whence a pipe H
communicates with each cell the inlet being arranged as near the bottom as possible.
The best results are obtained by causing the flow from tank D to be continuous
into the cells A; so as to overflow them continuously, this overflow is taken by
the pipe J which empties into a trough K which communicates with a cover tank L
by means of a gutter M. N are strainers or filters. When the liquid in the tank D,
has run out, it is pumped back into D by the pump O. It is found in practice

page_text: that the liquid can be used many times over, and that the slightest continual
inflow into the cells is sufficient to keep the battery in uniform and constant work.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed we declare that what we
claim is :-
==
The arrangement of means for imparting a continuous flow of liquid to a primary
battery for the prevention of polarization, as described and illustrated in the
accompanying drawings.
