Improvements in Compounds for Battery Solutions.
I, HENRY BLUMENBERG, Junior, residing at corner of White Plains Road and
De Milt Avenue, Wakefield, in the County of Westchester and State of New
York, United States of America, Chemist, do hereby declare the nature of this
invention to be as follows:-
I have heretofore employed bi-sulphate of an alkali or alkaline earth metal
in connection with a ter-sulphate of alumina and also chlorate of an alkali or
alkaline earth metal in connection with a bi-sulphate of an alkali or alkaline
earth metal. With the latter materials it is advantageous to employ a porous
cup to prevent a too violent operation, and in the materials first named the
reactions are not always sufficiently rapid and strong for some operations,
especially where zinc carbon electrodes are employed.
In the present invention I find that by the use of aluminum sulphate with
a chlorate and a bisulphate of an alkali or alkaline earth metal the action of
the solution is more regular and progressive and no porous cup is required,
and the solution is a medium between the solutions in the aforesaid applications,
and hence is adapted to batteries, especially open circuit batteries that are
brought into action periodically.
I have discovered that the following composition for a battery solution is
available, especially for the various zinc carbon type cells that are now so
generally used for all kinds of open circuit work. It gives a higher electromotive
force, the zincs always keep clean, furthermore it does not polarize as quickly
as the sal-ammoniac solution, it contains no creeping salts, and does not attack
or tarnish the connections as much as the sal-ammoniac solution. Further
more, the salt is not so bulky and not crystallize in the bottom of the glass
jar if it is not all dissolved.
This solution that I have found to give such excellent results is one con-
sisting of aluminum sulphate, bi-sulphate of soda and chlorate of soda. The
proportions are to be varied according to the conditions of the work required.
I find that the aluminum sulphate can be used in the form of a double sul-
phate of aluminum with the metals of the alkalies or alkaline earths, called
in the common term of alums. The bi-sulphate of soda can be replaced by
any other bi-sulphate of the metals of the alkalies or alkaline earths; and
furthermore the chlorate of soda can also be replaced by any other chlorate of
the metals of the alkalies or alkaline earths.

I, HENRY BLUMENBERG, Junior, residing at corner of White Plains Road and
De Milt Avenue, Wakefield, in the County of Westchester and State of New
York, United States of America, Chemist, 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:-
I have heretofore employed bi-sulphate of an alkali or alkaline earth metal
in connection with a ter-sulphate of alumina and also chlorate of an alkali or
alkaline earth metal in connection with a bi-sulphate of an alkali or alkaline
earth metal. With the latter materials it is advantageous to employ a porous

In the present invention I find that by the use of aluminum sulphate with
a chlorate and a bi-sulphate of an alkali or alkaline-earth metal the action of
the solution is more regular and progressive and no porous cup is required,
and the solution is a medium between the solutions aforesaid, and hence is

I have discovered that the following composition for a battery solution is
available especially for the various zinc-carbon-type cells that are now
universally used for all kinds of open-circuit work. It gives a higher electro-
motive force. The zines always keep clean. Furthermore, it does not polarize
as quickly as the sal-ammoniae solution, it contains no creeping salts, and does
not attack or tarnish the connections as much as the sal-ammoniac solution.
Furthermore, the salt is not so bulky and will not crystallize in the bottom
of the glass jar if it is not all dissolved.
This solution that I have found to give such excellent results is one con-
sisting of aluminum sulphate, bisulphate of soda, and chlorate of soda.
The proportions that I have found most advantageous to use, are the fol-
lowing:-
1 gallon of water,
8 ozs. chlorate of soda,
10 ozs. bisulphate of soda,
S ozs. aluminum sulphate.
I do not limit myself, however, to these exact proportions.
I find that the aluminum sulphate can be used in the form of a double sul-
phate of aluminum with the metals of the alkalies or alkaline earths called
in the common term of 66
alums." The bisulphate of soda can be replaced by
any other bisulphate of the metals of the alkalies or alkaline earths, and further-
more, the chlorate of soda can also be replaced by any other chlorate of the
metals of the alkalies or alkaline earths.
Having now particularly described and ascertamed the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
First. A compound for a battery solution, consisting of sulphate of aluminum,
bisulphate of the metals of the alkalies or alkaline earths, and a chlorate of the
metals of the alkalies or alkaline earths substantially as set forth

page_text: Second. A battery solution containing sulphate of aluminum, chlorate of
soda and bisulphate of soda, substantially as set forth.
Third. A battery compound consisting of sulphate of aluminum, as contained
in the sulphates of ammonia, potash or soda alums, a bisulphate of the metals
of the alkalies or alkaline earths and a chlorate of the metals of the alkalies
or alkaline earths, substantially as set forth.
