PROVISIONAL SPECIFICATION.
Improvements in Galvanic Batteries.
I, ALEXANDER SCHANSCHIEFF, of 44 Basinghall Street, in the City of London,
Electrician, do hereby declare the nature of this invention to be as follows :-
The object of this invention is to provide means whereby the elements can be
readily immersed into and taken out of the liquid or liquids.
I make the casing of the battery (or in the case of double fluid batteries each cell)
of a cylindrical form with a segment cut out of it by two planes approximately at
right angles to each other and passing through the axis. One of the flat sides so
formed constitutes the cover to which the battery plates are attached. This cover is
removeable so that the plates can be renewed and also to allow of the introduction of
fresh fluid; or a separate opening or openings may be provided for the latter
purpose.
The battery is mounted with its axis horizontal and it is filled about two-thirds full
of fluid, that is to say, the fluid occupies about one-half of the original cylinder.
By turning the battery about its axis until the cover lies in a vertical plane. the
elements are lifted out of the fluid, and by turning it so that the cover lies in a
horizontal plane the elements are immersed.
In some cases I fix the main cover and provide wedge shaped slots in it to receive
the elements which are wedge shaped at the top, and I employ a second cover to
come above the tops of the elements to hold them in place and to make a liquid
tight joint.

COMPLETE SPECIFICATION.
Improvements in Galvanic Batteries.
I, ALEXANDER SCHANSCHIEFF, of 44 Basinghall Street, in the City of London,
Electrician, 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 :-
This invention has for its object improvements in galvanic batteries.
In order that the battery elements may be readily raised out of the liquid when the
battery is not in use I make the battery of a cylindrical form but with a segment cut
out of it by two planes approximately radial and at right angles to each other. One
of these planes forms a cover, it is movable and the battery plates or elements are
fixed to it. This cylindrical battery is mounted with its axis horizontal and when in
use it is filled about two thirds full of liquid. By turning the battery one quarter
round in one direction or the other the plates or elements are lifted from the liquid or
are lowered into it. The battery may be made with any desired number of separate
cells divided the one from the other by partitions at right angles to the axis. It is not
essential that the battery should be cylindrical; it may be made with flat sides.
In the annexed drawings Figure 1 is a transverse section of a battery of the
cylindrical form above described; in this figure the plates or elements are represented
immersed in the liquid. Figure 2 shews the same battery with the plates or elements
raised out of the liquid. Figures 3 and 4 are similar views of a battery with flat
sides.
a. a are the sides of the battery, 6 the axis on which it is mounted, c is the
movable cover, d d are the plates or elements attached to the cover, e is an internal
radial partition to control the flow of the liquid when the battery is turned. The
D .

page_text: battery should be so mounted as to limit its movement about its axis to one quarter of
a revolution. In batteries in which two liquids are employed, each cell of the battery
will be divided by a porous partition or partitions.
It will be seen that in this battery the plates or elements occupy one third of the
internal capacity and the liquid occupies two thirds.
Amongst the advantages of the arrangements described are that ample room is
provided for the liquid, and also that the plates or elements are easily renewed. The
liquid also can be changed with great facility. Also that the portion of the battery
unoccupied by liquid forms a receptacle for whatever gas may be given off.
Immediately the gas begins to form a pressure the internal resistance becomes less
and the working capability increased, the result thus constituting a distinct advantage
over the ordinary form.
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 :-
1. A battery in which the plates or elements occupy one third of the capacity and
the liquid two thirds and in which the plates or elements are lifted from the liquid or
lowered into it by turning the battery one quarter round.
2. In a battery in accordance with the preceding claim, mounting the plates or
elements on a radial or nearly radial cover.
