IMPROVEMENTS IN ELECTRIC BATTERIES
Year: 1885

page_text: I GEORGE FREDERICK REDFERN of the General Patent Office, No 4, South Street,
Finsbury, in the County of Middlesex, Patent Agent do hereby declare the nature
of the said invention for "IMPROVEMENTS IN ELECTRIC BATTERIES " a communi-
cation from abroad by Jean Baptisto Neyraud of Lyons, in the Republic of
France, Electrician, to be as follows:-
This invention relates to improvements in electric batteries and has for object to
prevent the sodaic water (that is to say water saturated with a salt) at the bottom
of the porous pot from rising by the capillary attraction of the porous pot to the
upper part thereof and also to prevent the head or screw from becoming oxydised
and by these means to attain regular working and a much greater constancy.
In carrying out the invention I provide a battery the porous pot of which is
provided with a porcelain or earthenware cover or head glazed at the upper part.
This cover is provided with a nipple having a conical hole also glazed; this hole
is stopped by a lead plug in which is fixed a screw threaded rod serving as a
connection and provided with a nut. The lead plug is traversed by a platinum
wire which also passes through a suitable insulating material, sealing the plug ;
the wire is connected to a piece of carbon placed in the interior of the porous pot
and surrounded by small pieces of similar material; the bottom of the porous pot
is formed of insulating material.
By employing as above described a head or cover of porcelain or ceramic ware
and of metal a current is transmitted to the head or cover or connection by means
of an inoxydable wire also in contact with the sodaic water, preferably a solution
of ammonia.

Finsbury, in the county of Middlesex Patent Agent do hereby declare the nature
of this invention (a communication from abroad by Jean Baptiste Neyraud of
Lyons in the republic of France, Electrician) 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 improvements in electric batteries and has for object to
prevent the sodaic water that is to say water saturated with a salt at the bottom
of the porous pot from rising by the capillary attraction of the porous pot to the
upper part thereof and also to prevent the head or screw from becoming oxydised
and by these means to attain regular working and a much greater constancy.
In order to enable the invention to be fully understood I will describe the same
by reference to the accompanying drawing in which figure 1 is a sectional elevation
of an electric battery constructed according to this invention; figure 2 is a plan
of the cover of the porous pot; figure 3 is a vertical section of the battery taken
at a right angle to figure 1.
In carrying out the invention I provide a battery the porous pot of which is
provided with a porcelain or earthenware cover or head glazed from the upper
part E, down to the line marked F. This cover is provided with a nipple having
a conical hole also glazed; this hole is stopped by a lead plug I in which is fixed
a screw threaded rod J serving as a connection and provided with a nut. The
lead plug is traversed by a platinum wire which also passes through a suitable
insulating material K sealing the plug; the wire is connected to a piece of
carbon G placed in the interior of the porous pot and surrounded by small pieces
of similar material; the bottom K¹ of the porous pot is formed of insulating
material.
By employing as above described a head or cover of porcelain or ceramic ware and
of metal a current is transmitted to the head or cover or connection by means
of an inoxydable wire also in contact with the sodaic water, or water saturated
with a solution of ammonia.
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 :-
The construction and use of the improved electric battery substantially as
herein before described and represented in the accompanying drawing..
