IMPROVE- MENTS IN ELECTRICAL ACCUMULATORS OR STORAGE BATTERIES
Year: 1885

page_text: I CHAIMSONOVITZ PROSPER ELIESON, of Leytonstone, in the county of Essex,
Electrician, do hereby declare the nature of the said invention for "IMPROVE-
MENTS IN ELECTRICAL ACCUMULATORS OR STORAGE BATTERIES." to be as follows:-
The object of my invention is to improve the construction of electrical accumu
lators, or so called secondary batteries by providing a large area of acting surface
without pasting or otherwise attaching salts of lead to the plates before formation.
In constructing an accumulator according to my invention I use a leaden or other
suitable frame, which is divided into divisions or compartments.. I take a strip of
thin sheet lead slightly wider than the thickness of the lead frame; upon the said
strip I place a similar strip of sheet asbestos or other suitable insulating and acid
proof material. I roll up the strips so as to form a compact spiral cylindrical in
shape. I insert one of these spirals into each compartment or division in the before
mentioned frame.
A series of such frames are arranged in a suitable containing vessel and I pass a
current through them, forming them in the usual way, that is to say, oxydising
one plate to form + terminal, and hydrogenising the other to form terminal.
-
Among the advantages of my improved electrical accumulators may be mentioned
1st That there are no oxides of lead placed therein, which in a crude form are
liable to crumble, and by falling between the plates, short circuit the battery.
2nd That the spiral as constructed according to my invention affords a large acting
surface for electrical storage, whereby such storage may be carried out without
adding the unnecessary weight, which constitutes a serious objection against
accumulators when used for electrical traction or other kindred applications where
the minimum weight against time-storage is a desideratum 3rd That such a cell,
constructed according to my invention increases in capacity during its useful life,
which is only shortened by the disintegration of the leaden frame.

I CHAIMSONOVITZ PROSPER ELIESON of Leytonstone in the county of Essex,
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:-
The object of my invention is to improve the construction of electrical accumu-
lators, or so called "secondary batteries by providing a very large area of acting
surface without pasting or otherwise attaching salts of lead to the plates before
formation.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawing in which figures 1 and 2 represent front
and side views respectively of an electrical accumulator or storage battery made
according to my invention the box or containing vessel being shewn in section.
In constructing an accumulator according to my invention I use a frame a, made
ordinarily of lead, which is divided or formed into divisions or compartments b, of
any suitable shape, the divisions or compartments being shewn square in the
drawing, but it will be obvious that they may be of any other suitable shape.
I take a strip of thin sheet lead; upon the said strip I place another strip of sheet
asbestos or other suitable insulating and acid proof material. I roll up the strips
so as to form a compact spiral c, cylindrical in shape-I insert one of these
spirals c, into each compartment or division b, in the before mentioned frame a.
A series of such frames are arranged in a suitable containing vessel d, as shewn
in figure 2, and I pass a current through them, forming them in the usual way,
that is to say, oxydising one plate to form + terminal, and hydrogenising the other
to form terminal.
-
Among the advantages of my improved electrical accumulators may be mentioned
1st That there are no oxides of lead required to be placed therein, which in a
crude form are liable to crumble, and by falling between the plates, short circuit
the battery. 2nd That the spiral as constructed according to my invention affords
a very large acting surface for electrical storage, whereby such storage may be
carried out without adding the unnecessary weight which constitutes a serious
objection against accumulators when used for electrical traction or other kindred
applications where the minimum weight against time storage is a desideratum.
3d That such a cell, constructed according to my invention increases in capacity
during its useful life, which is only shortened by the disintegration of the leaden
frame.
In the drawing I have shewn the spirals c, as being of greater length than the
thickness of the frames a, but such is not necessary as the ends of the spirals may
be flush therewith.

page_text: 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. An electrical accumulator or storage battery such as is herein before described
formed by placing spirals of sheet lead whose surfaces are separated by suitable
insulating and acid proof material in suitable leaden or other frames or holders
substantially as hereinbefore described.
2. The manufacture and use of the improved electrical accumulator or storage
battery constructed substantially as herein before described and illustrated in the
accompanying drawing.
