I ALEXANDER SCHANSCHIEFF of Gipsy Hill in the County of Surrey Electrician
do hereby declare the nature of this invention to be as follows:-
My improved battery consists of elements of carbon and zinc immersed in a
liquid which I prepare as follows:-I take basic sulphate of mercury and I add to
it three times its weight of water. I then supply to the mixture strong sulphuric
acid which I let fall in drop by drop. The basic sulphate of mercury is gradually
dissolved.
After a time the drop of sulphuric acid falling in produces a precipitate; I then
immediately stop the process; I cool and filter the solution and so obtain a liquid
of a golden color with which I supply the battery. In the working of the battery
the mercury is recovered, it is found in a metallic form at the bottom of the cells.
I sometimes pack around the carbon element peroxide of manganese or peroxide
of lead mixed with broken carbon. I in this case provide a carbon cell to contain
the carbon element and the material packed around it.

My improved battery consists of elements of carbon and zinc, or in place of
carbon platinum or other metal may be employed. The elements are immersed in
a liquid which I prepare as follows:-I take basic sulphate of mercury and I add
to it three times its weight of water. I then supply to the mixture strong
sulphuric acid which I let fall in drop by drop. The basic sulphate of mercury
is gradually dissolved.
After a time the drop of sulphuric acid falling in produces a precipitate; I then
immediately stop the process; I cool and filter the solution and so obtain a liquid
of a golden colour with which I supply the battery. In the working of the battery
the mercury is recovered, it is found in a metallic form at the bottom of the cells
and also in a finely divided state as a heavy grey powder.
I construct my improved battery with cells having a cover of vulcanite wood or
other insulating material which supports the plates or elements and from which
they hang suspended. I prefer to have in each cell three plates or elements a
plate of zinc in the middle (it requires no amalgamation or other preparation) and
two plates of carbon one on either side of it connected with the insulated cover
in any usual or convenient manner. Such cells I couple one to another
heretofore.

I charge these cells with my novel liquid the preparation of which I will now
more fully describe; by boiling in the usual way' metallic mercury with oil of
vitriol I obtain a sulphate of "mercury. To this sulphate of mercury I add water
in 'the proportion of 30 lbs of water to 10 pounds of the sulphate of mercury-
decomposition ensues and the yellow basic salt which is almost insoluble in water
is formed. I then add very gradually sulphuric acid of specific gravity 1:8 stirring
constantly. The precipitate by degrees passes again into solution. Towards the
end of the operation I add the acid almost drop by drop never allowing the liquid
to become very hot and at the point where I find that the drop of sulphuric acid
falling into the liquid causes precipitation I stop the operation. I then allow the
liquor to settle and cool and draw it off for use when perfectly clear and with the
clear liquid I charge my battery cells.
This liquid is an entirely new chemical preparation and I find it to be most
suitable for use to form a single fluid battery. My improved battery is very
simple in use all the attention required being to fill the cells when the battery
is required and to remove the zinc plates from the cells to economise the liquid
when the battery is not required also when the exciting liquid is exhausted it is
necessary to supply fresh,

page_text: The electro motive force of the cell is high and it yields a strong and equable
current which can be maintained for hours almost without variation.
The mercury deposited in the cells during use is collected and is easily
reconverted into liquid to be again used in the battery.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
My improved galvanic battery in which a novel exciting liquid is employed
which can be prepared by the gradual addition of strong sulphuric acid under the
conditions herein set forth to basic sulphate of mercury held suspended in water.
