HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London, 'IMPROVEMENTS IN ACCUMULATORS FOR STORING
ELECTRICAL ENERGY AND [IN] DEVICES FOR FACILITATING THE TRANSPORT THEREOF."
[A communication to him from abroad by Nicolas de Kabath, of Paris, France,]
This invention relates to electric accumulators in which lead plates are employed,
and to devices for facilitating the removal or transport thereof
In order that the said invention may be more readily understood I have shown
in the accompanying drawings, by way of example only, one mode of carrying the
said invention into practice
Figure 1 is a front elevation of a plate for the accumulator
Figure 2 is a section of the same on the lino 1-2 Figure 1
Figure 3 is a section of part thereof on the line 3-4, Figure 1
Figures 4 and 5 represent, respectively, a plan of a positive plate and a plan of a
negative plate
Figure 6 represents the case or box of the accumulator provided with shafts
or handles fixed to, or forming extensions of, two of the walls or sides of the box
or case
Figure 7 represents a box or case provided, on two of its parallel faces, with
hooks or lugs into which shafts or handles may be inserted for transporting or
removing the accumulator
In Figures 1, 2, 3, 4, and 5 like letters indicate corresponding parts
In order to construct a plate according to the said invention, I take a sheet of
lead a of suitable thickness, in which I form a number of incisions b in the form of
the letter V, of an arc of a circle, of the letter U, or of any other suitable form, I
then fold the parts of metal liberated by these incisions in such a manner as to
form projecting curled portions or buckles c, as shown in Figure 3. In Figure |
only the lower right hand corner of the plate is shown with the buckles formed
thereon When the pieces of metal are thus folded I obtain a plate having a
number of apertures & and projections or buckles c

page_text: I then fold these plates as shown in Figures 4 and 5 so as to form positivo and
negative electrodes having external extensions e, which servo for coupling them
together. In the spiral "plate thus formed the apertures d allow the liquid to
circulate in a transverse direction, and the buckles c, by keeping the different folds
of the plate separated from one another, permit the circulation of the liquid in a
vertical direction, and at the same time, augment the effective surface of the plate.
The plates thus manufactured can be treated by any suitable process and be
mounted in any convenient manner in the vessel of the accumulator. But in order
to facilitate the removal and replacing of the plates I prefer to arrange them
parallel to one another in a rectangular box or case
According to a modification of the above described mode of construction, I make
the plates by stamping the metal in such a manner as to form parallel lines of
buttons or projections at suitable distances apart, and I perforate the upper part of
each of these buttons
When the plate is wound or folded the said buttons will maintain the separation
of the different folds or coils of the plate, and the apertures or perforations will
permit the circulation of the liquid
In order to facilitate the removal of the accumulator, the weight of the apparatus
being considerable, the sides of the box or case are extended to form arms (Figure 6)
in such a manner that two men can lift the apparatus; or the said sides are
provided with hooks or lugs (Figure 7) into which shafts or handles can be passed;
or if theso means are not sufficient for the transport of the accumulators, I employ
the form of construction shown in Figures 8 and 9, that is to say I combine a
carriage a having two wheels with an arm b articulated to the piece c and forming
a lever.
It will be seen that by bearing upon the lever b of the said carriage the
accumulator will be raised.
The interior of the box or case is composed of hard india-rubber, lead, or other
suitable material
