COMPLETE SPECIFICATION.
An Improved Insulating and Carrying Frame for Accumulator
Electrodes.
I, FRIEDRICH WILHELM SCHNEIDER, of Triberg, in the Empire of Germany,
Engineer, 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 an insulating and carrying framing, which is essentially
intended for horizontal, for instance, for tubular or trough-shaped accumulator-
electrodes, and has especially the purpose to diminish as much as possible the weight
of the accumulator, to construct the same in a more favourable manner, to augment
its durability, and to allow when necessary of a quick exchange of the single
electrodes.
In the annexed drawing
Fig. 1 is a front view of a form of construction of this framing with therein
arranged eletrodes.
Fig. 2 is a cross section, and
Fig. 3 a plan view thereof.
The framing consists of perforated insulating plates a, a¹, a², a³, produced
conveniently of hard-rubber, of which always two enclose a row of tubular or
trough-shaped electrodes b, b¹ lying over another. All the perforated plates are
connected with one another by connecting pieces or cross-bolts c, which simul-
taneously serve as carriers for the electrodes b, b¹, arranged in groups over one
another. In the form of construction illustrated 6 are the negative and are the
positive electrodes.
In this carrying frame, for instance, the connecting bolts care fixed in the one end
plate a of the framing by being screwed in, or the like, and hard-rubber-sockets, d,
of the width of the electrodes, b, to be inserted are slid over these bolts. These
sockets & regulate the distance of the plate a from the next perforated plate a¹,
which provided with corresponding bores, is slid over the bolts c.
Then again
hard-rubber-sockets d are inserted as counter-bearings for the third plate a², and
one continues in this manner, until the arrangement has obtained the desired size.
The last plate, which in the shown form of construction is indicated by a³, is fastened
by small nuts e screwed on the bolts c. Between each 2 plates a, a¹, a², a³,.
then inserted the electrodes b, b' filled with paste, these at the ends are connected
to one another in vertical rows by means of a lead-strip f serving as current-
conductor.
... are
By using the previously described carrying framing, the weight of the accumulator
is considerably diminished, as one need not as in hitherto used accumulators take into
consideration the mechanical solidity of the real paste-carrier, but only a good
current-conduction to the single electrodes, whilst the stability of the structure of
the cell is determined by the proportionally light insulating and carrying framing
itself.
Further the single electrodes by means of this carrying framing can be brought
much nearer to one another than before, without short circuiting. By this circum-

page_text: stance the volume and the weight of the electrolyte can be diminished to the
theoretically necessary quantity.
Finally it may be mentioned, that by means of the framing described elements of
any size can be connected as a whole, while the single electrodes or electrode-rows
can easily be taken out at any time for the purpose of exchange or repairs.
Owing to the said properties the new insulating and carrying framing is especially
convenient for use in transportable accumulators, as used for traction purposes.
The duration of thus constructed accumulators is extraordinarily long.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner, the same is to be performed, I declare that what I
claim is :-
1. An improved insulating and carrying framing for accumulator electrodes,
consisting of perforated insulating plates a, a¹, a², a³. . . which are connected in such
a manner with one another by bolts or bridges c, that the distance between each two
plates can be regulated correspondingly to the width of the electrodes b, b¹ to be
inserted, for the purpose of diminishing the weight of the accumulator, and to
improve its construction to augment its durability, to avoid short circuiting, to
diminish the weight of the electrolyte and to facilitate the exchanging of the single
electrodes.
.
2. A form of construction of the insulating and carrying framing as in Claim 1,
in which the distance of the perforated insulating plates a, a, a², a³
from one
another is determined by sockets d of the width of the electrodes b, b¹ to be inserted,
these sleeves being slid over the connecting bolts c.
Dated is 22nd day of May 1897.
