Improvements in Electric Accumulators or Storage Batteries.
I, ALBERTO TRIBELHORN, 355, Calle de Bolivar, Buenos Ayres, in the Argentine
Republic, do hereby declare the nature of this invention to be as follows:
-
The present application relates to improvements in electric accumulators or
storage batteries characterized by a special arrangement of the electrode plates.
In my improved accumulator, the positive and negative plates are made in a
cup-like shape in such a manner as to form, of themselves, the receptacle which
contains the electrolyte; these plates, which are of the form of an open vessel
on their upper side, or more or less bell-shaped, square, round or of other con-
venient shape, fit into one another, one above the other, leaving between the
upper and under surfaces respectively of each pair of contiguous plates a free
space in which is contained the electrolyte. The active material is spread on
both the convex or concave surfaces of the plates or on the inner and outer faces
of the bottoms of the receptacles.
To aid the description, I have shown, in principle, in the accompanying draw-
ings, by way of example only, my improvements in electric accumulators.
Figure 1 is a vertical section of one form of my improved accumulator.
Figures 2 to 9 show various forms of vase-electrodes.
Figure 10 shows another form or modification of the accumulator shown in
Figure 1.
Figure 11 is a plan of one of the elements of the same.
Figures 12, 13 and 14 are vertical sections of further modifications of my
improved accumulator.
Like letters indicate corresponding parts throughout the drawings.
My improved accumulator consists essentially of receptacles a open on their
upper sides and more or less bell-shaped, square, round, or of other convenient
shape, Figures 1 to 9, made of conducting material by casting, stamping or in
any other suitable manner.
The active material (positive b, negative c) is spread either on both the external
and internal faces of the bottom of each receptacle or on the convex and concave
parts of the same.
This active material is spread directly upon the surface of the receptacles a
but preferably is held by grilles or other suitable supports. A very advan-
tageous arrangement consists in applying the active material in the form of bands
or strips as shown in Figures 12 and 14.
All the positive active bands or strips b are fixed on the convex or exterior
077

page_text: sides and all the negative active bands or strips c, on the concave or interior
sides.
These bands or strips are fixed by means of screws, rivets, solder or any other
suitable means that will permit the passage of the current.
It is to be understood that I reserve the right to build up the bands or strips
of active material in any convenient manner.
To form a battery, one of the receptacles a is placed upon an insulating
pedestal d, and thereon are piled successively any desired number of similar
receptacles, care being taken to insulate them one from the other by the insula-
tors e made in the form of spheres of glass, porcelain, ebonite or the like.
These receptacles a, thus superposed, form a series of compartments for the
reception of the electrolyte.
The receptacles a are connected together in any suitable order, in the ordinary
manner; for this purpose each receptacle a is provided with a lug f.
If the two extreme elements of the battery, formed in this manner, are con-
nected to the two extreme poles of an electric generator, it forms a pole on the
interior face or concave side and an opposite pole on the exterior face or convex
side of each receptacle.
The total electro-motive-force of the battery is equal to the sum of the electro-
motive-forces of the elements of which it is composed.
When it is required to make the apparatus in a large size, it is preferable to
form the receptacles a of iron, steel or the like and to cover them with lead
(Figure 9); these receptacles can be provided with suitable rims or hooks so as
to permit of their being readily lifted.
When it is required to transport the battery, the receptacles a box themselves
into one another so as to prevent the liquid from being spilt (Figures 6, 8, 13
and 14).
In order to reduce the weight of the accumulator, the bottoms only- of the
receptacles a are sometimes made of metal and the sides of ebonite as shown in
Figure 8.
In the arrangement shown in Figures 10 and 11, the insulators e are placed
at the four corners, in beds or seats provided for this purpose, at the four angles
of the receptacle a.
By this arrangement the different receptacles a are at the same time insulated
from and perfectly secured to each other.
In the types represented in Figures 13 and 14, each receptacle a presents a
rim g forming the lateral wall, fitting on the rim of the receptacle next below,
in such a manner as to form an unbroken exterior.
To prevent evaporation and the upsetting of the electrolyte, a joint of caout-
chouch, is interposed between adjacent receptacles a.
Each receptacle a is provided with a small tube i for the liberation of gas.
The negative bands or strips c of active material can be mounted on the exterior
face or convex side of each receptacle a and the positive bands or strips 6 fixed
on the rims g (Figure 13).
This arrangement permits a certain free space to be formed below the active
material, which is filled with the electrolyte, and into which the particles of the
active material that drop off can fall.
These elements are preferably constructed of iron, with a casing of lead, so as
to be very strong and to permit the setting up of a battery composed of a large
number of elements.
My invention is applicable not only to lead accumulators but to all other kinds.
The novel construction that I have devised provides solid accumulators pre-
senting a large surface within a small compass; an easy mounting of the parts,
the form of these elements ensuring their being held together without the use
of screws, or solder; the electrodes taking the place of independent receptacles
and not requiring special insulators.

page_text: It is to be understood that my improved electric accumulator can be made
in various shapes and sizes and I can modify the accessory arrangements accord-
ing to the different applications.

Improvements in Electric Accumulators or Storage Batteries.
I, ALBERTO TRIBELHORN, of 355, Calle de Bolivar, Buenos Ayres, in the Argentine
Republic, 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 present application relates to improvements in electric accumulators or
storage batteries characterized by a special arrangement of the electrode plates.
In my improved accumulator, the positive and negative plates are made in a
cup-like shape in such a manner as to form, of themselves, the receptacle which
contains the electrolyte; these plates, which are of the form of an open vessel
on their upper side, or more or less bell-shaped, square, round or of other con-
venient shape, fit into one another, one above the other, leaving between the
upper and under surfaces respectively of each pair of contiguous plates, a free
space in which is contained the electrolyte. The active material is spread on
both the convex and concave surfaces of the plates or on the inner and outer faces
of the bottoms of the receptacles.
To aid the description, I have shown, in the drawings filed with my Provisional
Specification, but by way of example only, my improvements in electric accumu-
lators.
Figure 1 is a vertical section of one form of my improved accumulator.
Figures 2 to 9 show various forms of vase-electrodes.
Figure 10 shows another form or modification of the accumulator shown in
Figure 1.
Figure 11 is a plan of one of the elements of the same.
Figures 12, 13 and 14 are vertical sections of further modifications of my
improved accumulator.
Like letters indicate corresponding parts throughout the drawings.
My improved accumulator consists essentially of receptacles a open on their
upper sides and more or less bell-shaped, square, round, or of other convenient
shape, Figures 1 to 9, made of conducting material by casting, stamping or in
any other suitable manner.

and internal faces of the bottom of each receptacle or on the convex and concave
parts of the same.
This active material is spread directly upon the surface of the receptacles a
but preferably is held by grids, grilles or other suitable supports. A very advan-
tageous arrangement consists in applying the active material in the form of bands
or strips, as shown in Figures 12 and 14.
All the positive active bands or strips 6 are fixed on the convex or exterior
sides and all the negative active bands or strips c; on the concave or interior
sides.

page_text: These bands or strips are fixed by means of screws, rivets, solder or other
suitable means that will permit the passage of the current.
It is to be understood that I reserve the right to build up the bands or strips
of active material in any convenient manner.

When it is required to transport the battery, the receptacles a fit into one
another so as to prevent the liquid from being spilt (Figures 6, 8, 13 and 14).
In order to reduce the weight of the accumulator the bottoms only of the
receptacles a are sometimes made of metal and the sides of ebonite as shown in
Figure 8.

In the arrangement shown in Figures 10 and 11, the insulators e are placed
at the four corners, in beds or seats provided for this purpose, at the four angles
of the receptacle a.
By this arrangement the different receptacles a are at the same time insulated
from and perfectly secured to each other.
In the types represented in Figures 13 and 14, each receptacle a is provided with
a rim g forming the lateral wall, fitting on the rim of the receptacle next below,
in such a manner as to form an unbroken exterior.
To prevent evaporation and the upsetting of the electrolyte, a joint of caout-
chouch is interposed between adjacent receptacles a.
Each receptacle a is provided with a small tube i for the liberation of gas.
The negative bands or strips e of active material can be mounted, for example,
on the exterior face or convex side of each receptacle a and the positive bands or
strips b fixed on the interior face or concave side (Figure 13).
This arrangement permits a certain free space to be formed between any two
adjacent receptacles, which is filled with the electrolyte, and into which the
particles of the active material that drop off can fall.
These elements are preferably constructed of iron, with a casing of lead, so as
to be very strong and to permit the setting up of a battery composed of a large.
number of elements.
My invention is applicable not only to lead accumulators but to all other kinds.
The novel construction that I have devised provides solid accumulators pre-
senting a large surface within a small compass; an easy mounting of the parts,
the form of these elements ensuring their being held together without the use
of screws, or solder; the electrodes taking the place of independent receptacles
and not requiring special insulators.
It is to be understood that my improved electric accumulator can be made
in various shapes and sizes and I can modify the accessory arrangements accord-
ing to the different applications.

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
The improved electric accumulator wherein each plate is made in the form of
a cup or receptacle and fits onto the plate below so as to leave between them a
space in which the electrolyte is contained, the active material being applied on
the convex and concave surfaces of these receptacles or on one of the internal and
external faces of the bottom thereof, and the said plates are separated by any
suitable insulators, substantially as hereinabove described with reference to the
drawings, for the purposes specified.
