An Improved Arrangement of Electric Battery with Means for
Regulating the Amount of Submersion or Withdrawal of the
Positive Plates.
I HENRY CARTER of 8 Charlton Street, Euston Road, Middlesex Electrical
Engineer do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to arrange an electric battery in which the electric
energy developed is regulated and proportioned to the consumption with mathematical
accuracy thereby effecting a saving in the consumption of the negative electrodes as
well as ensuring a constant and regular “diagram” of the electric light when the battery
is employed for lighting purposes.
According to my invention I form the cell of lead preferably rectangular in shape
and very elongated, the carbons being fixed on each face in the interior which allows
the negative electrode to be attacked regularly.
The movement which causes the withdrawal or the submersion of the positive plates
to take place has been so arranged as to definitely regulate the consumption and
consists in connecting all the electrodes on a platform above the cells and arranged
to slide up or down in the outer wooden casing, the platform being held at any
desired height by a set screw or equivalent means, the said set screw pressing against
side pieces attached to the under part of the platform. On this platform all the
connections existing between the electrodes of contrary poles are fixed. The zinc or
negative electrodes are perforated so as to facilitate the passage of the exciting liquid
and to diminish polarization.
With this battery I employ a switch of simple construction consisting of a short
pillar and a set screw and suitably insulated into which insulation the binding screw
passes to nip the conductor arranged in it.

An Improved Arrangement of Electric Battery with Means for
Regulating the Amount of Submersion or Withdrawal of the
Positive Plates.
I HENRY CARTER of 8 Charlton Street, Euston Road, Middlesex, Electrical
Engineer 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 :-
The object of my invention is to arrange an Electric Battery in which the electric
energy developed is regulated and proportioned to the consumption with mathematical
accuracy thereby effecting a saving in the consumption of the positive plate as well
as ensuring a constant and regular "diagram" of the Electric Light when the
battery is employed for lighting purposes.
According to my invention form the cell of lead or other suitable material,
preferably rectangular in shape and very elongated, the carbons being fixed in each
face in the interior but stops short of the bottom so that the sulphate of zinc may
become deposited in the lower part of the casing which allows the positive plate
to be attacked regularly.
The movement which causes the withdrawal or the submersion of the positive
plates to take place being arranged to definitely regulate the consumption and consists
in connecting all the plates on a platform above the cells and arranged to slide up
or down in the outer wooden casing the platform being held at any desired height by
a set screw or equivalent means, the said set screw pressing against side pieces
attached to the under part of the platform. On this platform all the connections
existing between the plates of contrary poles are fixed. The zinc or negative
electrodes are perforated with three holes so as to facilitate the passage of the exciting
liquid and to diminish polarization.
With this battery I employ a switch of simple construction consisting of a short
pillar and a set screw suitably insulated, into which insulation the binding screw
passes to nip the conductor arranged in it."
This invention will be clearly understood by reference to the annexed drawings
in which Figure 1 is a section of the cell a with carbons b attached and Figure 2 a
view of the carbon plate 6 galvanised at c to enable it to be attached to the lead by
solder. Figure 3 is the zinc plate z. Figure 4 is the combined binding pillar and
switch d with insulation at e, e¹ being the conducting-wire nipped therein.
Figure 5 is a modified arrangement of the combined binding pillar and switch in
which the head of the screw is formed of insulating material and the lower end
of the screw thread is terminated by a disc or enlarged portion g to act as a stop piece
and prevent the binding screw being unscrewed beyond a certain limit.
Figure 6 is a plan of the battery box k platform h negative terminal i and positive
terminal for six cells the zincs being fixable at any desired height by the set screw m

Figure 7 is a plan of cells with platform removed.
Figures 8 and 9 are front and end views respectively of cells a and platform h
complete in box k with adjusting screws / and m.
Figure 10 is a transverse section of the box k and cells a b.
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 :-
1. The improved arrangement of electric battery provided with a movable platform
carrying the connections and the positive plates the platform being supported above
the battery and maintained at any desired height by the set screw m in the manner
hereinbefore described and shown at Figures 6. 8. 9 and 10 of the annexed drawings.
2. Fixing short carbon plates b to the inner faces of battery cells a as set forth and
as shown at Figures 1. 9 and 10 for allowing the negative electrodes to be attacked
in an uniform and regular manner.
3. Perforating or making three centrally formed apertures in the zinc or negative
electrodes as shown at Figure 3 to facilitate the passage of the exciting liquid and to
diminish polarization the zinc being kept clean by free oxfoliation.
4. The combined binding screw and switch pillar shown at Figure 4 and the
modified arrangement of same shown at Figure 5.
