NORTONAL SE PUIFICATION,
Improvements in Gratings or Supports for Electrical Accumulator
Plates.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, as com-
municated to me by Messieurs Cambier et Cie., of Lille, France, to be as
follows:-
The object of this invention is to substitute for the lead hitherto used in making
beds or supports for electrical accumulator plates, a material that is light, a
bad conductor of electricity, and but slightly affected by diluted acids: for
example, ebonite, vulcanised fibre, wood impregnated with paraffin, celluloid, &c.
Having, with any one of these materials, constructed a rigid frame of
rectangular shape, it is pierced, in two opposite and parallel sides with two series
of holes at equal spaces apart, in such a manner that they are exactly opposite
one another. The grating is then formed by inserting in these holes, one after
the other, and from one side to the other, a metallic wire, which is not affected
by acids, such as lead for example. This wire is strained by any suitable means,
and the two pierced bars are each furnished with a longitudinal groove, on their
outer edge, arranged so that the wire is completely sunk in the bar; the size of
this groove varying according to the dimensions of the accumulator.
The gratings thus formed are then furnished, according as they are intended
for use as positive or negative plates, with suitable agglomerations, which are
fixed by powerful pressure from the two sides of the frame, by means of
suitable apparatus.
In this manner, perfect adherence of the whole plate of oxide to the con-
tinuous metallic sunken wire, is obtained.
The current, which runs through this wire, acts more uniformly at every
point of the oxide mass, than with any other form of plate, so that the charging
of the accumulator is rapid and certain.
The position of the wire presents the same advantages in regard to the dis-
charge, and ensures the production of a continuous and constant current.
The joining together of the plates is effected in the simplest manner by the
extremities of the metallic wire. The escape of gas from the outer edges of
the ordinary lead frames arranged side by side at a little distance apart, is
avoided by this invention as the material of the frame, which material is a non-
conductor, completely covers the metallic wire.
Further, there is much less tendency to the production of short circuits, as
the active material is not so easily detached, because the metallic wire yields
to the deviations resulting from the passage of the current.
Dated this 19th day of July 1898.

Plates.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, as com-
municated to me by Messieurs Cambier et Cie., of Lille, France, to be as
follows:-
This invention relates to gratings or supports for electrical accumulator plates
and is shewn by way of illustration in the accompanying drawings wherein Fig. 1
is a front view in elevation of the accumulator frame, Fig. 2 is a transverse
section and Fig. 3 a horizontal plan in section of the same frame.
The object of this invention is to substitute for the lead hitherto used in making
beds or supports for electrical accumulator plates, a material that is light, a
bad conductor of electricity, and but slightly affected by diluted neids for
example, ebonite, vulcanised fibre, wood impregnated with paraffin, celluloid, etc.
Having, with any one of those materials, constructed a rigid frame of
rectangular shape, A B C D, it is pierced, in two opposite and parallel sides
with two series of holes at equal spaces apart 1, 2, 3, 4, 5, 6, 7, 8, 9, in such a
manner that they are exactly opposite one another. The grating is then formed
by inserting in these holes one after the other, and from one side to the other,
a metallic wire, W which is not effected by acids, such as lead for example.
This wire strained by any suitable means, and the two pierced bars are each
furnished with a longitudinal groove, on their outer edge, arranged so that the
wire is completely sunk in the bar; the size of this groove varying according to
the dimensions of the accumulator.
The gratings thus formed are then furnished, according as they are intended
for use as positive or negative plates, with suitable agglomerations, which are
fixed by powerful pressure from the two sides of the frame, by means of
suitable apparatus.
In this manner, perfect adherence of the whole plate of oxide to the con-
tinuous metallic sunken wire, is obtained.
The current, which runs through this wire W, acts more uniformly at every
point of the oxide mass, than with any other form of plate, so that the charging
of the accumulator is rapid and certain.
The position of the wire presents the same advantages in regard to the dis-
charge, and ensures the production of a continuous and constant current.
The joining together of the plates is effected in the simplest manner by the
extremities of the metallic wire. The escape of gas from the outer edges of
the ordinary lead frames arranged side by side at a little distance apart, is
avoided by this invention as the material of the frame, which material is a non-
conductor completely covers the metallic wire.
Further there is much less tendency to the production of short circuits, as
the active material is not so easily detached, because the metallic wire yields
to the deviations resulting from the passage of the current.
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 construction and fitting up an electric accumulator frame in the manner
indicated above and with the materials as mentioned.
2. In an electric accumulator frame the special arrangement of the continuous

page_text: wire through which the current runs forming the connection between the two
horizontal transverse pieces as indicated above.
3. In electrical accumulator frames the method of coupling these frames
together and placing them in juxtaposition for the purpose of forming the active
elements, substantially as described.
