London and THOMAS DANIEL Cox PARKER Electrician of 81 Shaftesbury Road
Crouch Hill in the County of Middlesex do hereby declare the nature of this
invention to be as follows:-
This Invention relates to improvements in voltaic or galvanic batteries for
producing the electric light by incandescent or other means such batteries being
applicable to other purposes.
The object of this invention is to counteract endesmose in the porcus cell and to
enable the cells to be refilled with fresh liquid without first having to discharge
the spent liquid, the battery box is advantageously constructed of wood cells lined
with paraffin wax or some other suitable substance, and the cells are so arranged
that space is left between them as a receptacle for the spent liquid or the overflow.
The porous pot is constructed or fashioned with a lip or spout projecting over
the cell and discharges into the receptacle above described.
By this arrangement the connections of the carbon plates or electrodes are
protected from the liquid coming in contact with them and causing corrosion and
also preventing the liquid of the porous pot overflowing and mingling with the
liquid of the outer cell by which means the zinc is preserved from unnecessary
destruction by the action of the stronger liquid coming in contact with it. And
further in order to prevent any unpleasant smell which may arise from decom-
position by working the battery continuously for a number of hours, I groove the
top edge of the battery case and tongue the bottom edge of the lid or cover and fix
a piece of india rubber or other suitable material in bottom of groove so that when
the lid is closed it is a perfectly tight joint impervious to any fumes which may be
generated by continuous action of the battery by allowing the battery to rest a
short time before opening the lid, thus the fumes that arise from continual action
are condensed and the battery is quite inodorous.

page_text: We, JOHN PRICE REES, Civil Engineer of 2 Great St. Helens in the City of
London and THOMAS DANIEL COX PARKER Electrician of 81 Shaftesbury Road
Crouch Hill in the County of Middlesex 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 relates to improvements in voltaic or galvanic batteries for
producing the electric light by incandescent or other means such batteries being
applicable to other purposes.
The object of our improvements is to counteract endesmose in the porous cell
and to enable the cells to be refilled with fresh liquid without first having to
discharge the spent liquid, the battery box is advantageously constructed of wood
cells lined with paraffin wax, or with india rubber vulcanite or any other suitable
substance or made or moulded thereof and the cells are arranged so that space is
left between them as a receptacle for the spent liquid or the overflow and such
receptacle can be fitted with a tap or cock to draw off such overflow or waste.
The porous pot is constructed or fashioned with a lip or spout projecting over
the cell and discharges into the receptacle above described.
By this arrangement the connections of the carbon plates or electrodes are
protected from the liquid coming into contact with them and causing corrosion
and also preventing the liquid of the porous pot overflowing and mingling with
the liquid of the outer cell by which means the zinc is preserved from unnecessary
destruction by the action of the stronger liquid coming in contact with it.
By raising the divisions of the cells higher than the front or by fitting spouts to
the cells or by any other suitable means the cells can be made to discharge by an
overflow into the recéptacle before mentioned.
By this means a feed can be supplied to either or both porous pots and cells if
required thus obviating the necessity of wholly discharging the cells and porous
pots. And further in order to prevent any unpleasant smell which may arise from
decomposition by working the battery continuously for a number of hours we
groove the top edge of the battery case and tongue the bottom edge of the lid or
cover and fix a piece of india rubber or other suitable material in the bottom of the
groove so that when the lid is closed it is a perfectly tight joint impervious to any
fumes which may be generated by continuous action of the battery, by allowing
the battery to rest a short time before opening the lid the fumes that arise from
continual action are condensed and the battery is inodorous.
As a further means of arresting endesmose and obviating local action we provide
a sliding attachment or envelope to the battery case which can be worked either
with or without a water joint. To this sliding attachment or envelope is affixed a
frame advantageously made of gutta percha vulcanite or of other suitable substance
which frame carries and supports the porous pots carbon electrodes and zinc plates
or sections or divisions of cells which are so constructed and affixed to the sliding
attachment or envelope that by this or equivalent means the porous pots and zinc
plates can be raised and supported out of or above the positive fluid in the cells.
thus preventing local action.

page_text: And in order that our improvements may be more clearly understood and readily
carried into practice we will now proceed to describe the drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a longitudinal section Figure 2 a transverse section and
Figure 3 a plan of a voltaic battery arranged and constructed in accordance with
our improvements.
a a is the battery box containing the series of cells b b advantageously made of
gutta percha or of other suitable substance moulded in one complete series cc is a
frame also made advantageously of gutta percha. This frame c is formed with
double folded ends c¹ c¹ and a bottom the sides being left open thus forming &
series of cells with open sides such series of open cells descending into the series of
cells b b containing the exciting fluid of the battery. The sections or series of
open cells c c are supported upon the cross bars ³ ³ connected to the outer frame
or enveloped by lifting which the open cells cc containing the porous pots e e
carbon plates ff and zinc plates g g can be raised out of the cells bb and can be
supported above the liquid in the cells b by means of the binding nuts and
screws a¹ a¹ which pass through the ends of the battery box a and are fixed to
plates fixed in the ends of the frame d. The zinc plates g are kept in position by
the parts of the cells c as shown.
The porous pots e e are formed with overflow spouts or lips e¹ e¹ projecting over
each cell e to discharge the spent liquid into the receptacle h formed between the
cells bb from which it can be drawn off by the cock i at the bottom.
A lid or cover d¹ is placed over the cells the top edge of the battery being
grooved and lined with india rubber or other suitable material and the under edge
of the cover d² is formed with a tongue to fit into the groove and thus form an air
tight joint and a water or other suitable air tight joint may be applied to the
lower part and edge of the frame or envelope d and the bottom of the battery
box a to prevent the escape of fumes from the battery thus making the battery
inodorous as before described.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The improved arrangement and construction of voltaic batteries in such manner
that the porous pots carbon and zinc plates can be so supported that they can be
raised or lifted out of the cells containing the exciting fluid and thus arrest the
action of the battery substantially as herein before described and represented in the
drawings annexed.
We also claim the forming of the porous cells with overflow lips or channels to
conduct the spent liquor into a receptacle forming part of or combined with the
battery substantially as shown and described.
We also claim the application of an envelope or cover to the battery box
arranged with a water or other air tight joint to prevent the escape of fumes from
the battery substantially as shown and described in the drawings annexed hereto.
