New and Improved Methods of Charging and Recharging, Cleansing,
Changing, and Varying the Chemicals and Liquids Used in
Secondary Batteries (or Accumulators).
1, JAMES TARBOTTON ARMSTRONG, of 31 Aldermanbury, in the City of London,
Analytical and Consulting Chemist and Electrician, do hereby declare the nature of
my said invention to be as follows:-
My invention relates to secondary electrical batteries (or accumulators).
In carrying out my invention I supply, charge, recharge, cleanse, change and vary
the chemicals and liquids used in such secondary batteries (or accumulators) in the
same manner and by similar methods means and appliances as those described in
Letters Patent granted to me or applied for Nos. 68788 398 85738 and 10,824.

I, JAMES TARBOTTON ARMSTRONG, of 31 Aldermanbury, in the City of London,
Analytical and Consulting Chemist and Electrician, do hereby declare the nature of
my said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Whereas in the manipulation and management of electrical accumulators (or
secondary batteries,) it frequently happens that the liquor requires to be removed, and
other mixtures substituted therefor; or the battery requires to be cleansed and fresh
liquor supplied thereto; and such operations require to be promptly cheaply and
effectively carried out. I also find it advantageous and beneficial to the battery in
every respect to occasionally give the plates a rest, by entirely removing the liquor for
a time.
'
Now the object of my invention is to carry out. such oporations in an efficient
manner, and to provide means for facilitating such operations.
In carrying out my invention, I make use of cisterns which are capable of being
raised and lowered, and usually balanced, or nearly so, in an analogous manner to
those described in my former Specifications for Primary batteries 6878** 398** 857380
and 10,824 one of such cisterns being so placed as to receive the liquor from one or
more of the batteries, and the secondary batteries having connection to them as in my
Primary Battery arrangements; I then allow the same to drain away, while the other
cistern is retained in position to refill the batteries, when required.
I also provide bottles of suitable acids, fitted with flexible or other tubes or
connections; and I so connect the same with one or both of the cisterns, that the same
may trickle into. and slowly mix with the clean water in such cistern or cisterns; such
bottles of liquor being adapted to certain definite periods of working, as required.
By my improved method of working, and using a cleansing tank I am enabled to
entirely obviate the deleterious effects arising from the accumulation of sulphate or
other deposit becoming too thick to be completely reduced; and there is no possibility
of the bad conducting properties of this sulphate or other deposit producing short
circuiting.
Also the electrolyte can always he kept at one uniform specific gravity, so that it
remains in the condition of least resistance; and this can be altered to any extent in
a few moments.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
The application use and adaptation of the new and improved method of charging
and recharging, cleansing, changing, and varying the chemicals and liquids used in
secondary batteries or accumulators, substantially as and for the purposes herein
before described.
