1. HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., l'atent Agents,
Southampton Buildings in the County of Middlesex 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 :-
My invention relates to that class of galvanic batteries which are provided with
reinforcing or feeding cups; and it consists in the certain novel features hereinafter
fully set forth and claimed, the object being to produce a simpler, cheaper and more
effective device of this character than is now in ordinary use.
In the accompanying drawing
Figure 1 is a top plan view of an improved galvanic battery and
Figure 2 a vertical section taken on line x, x, Figure 1.
A represents the outer or containing jar and B the porous or inner jar.
The outer jar is made of glass, or similar material, and provided with a cover C,
which may be secured to the body of the jar, and made air and water tight in any
convenient and suitable manner.
The inner jar is preferably composed of biscuit porcelain or analogous porous
materials, and is provided with legs m, on which it is supported within the jar A.
A feeding or reinforcing cup D, is formed integral with the body of the porous
jar B, the said cup being arranged vertically at one side of the said jar and crescent-
shaped in horizontal section, as shown by dotted lines in Figure 1.
Projecting from the outer side of the porous jar B, near its bottom, there is a
shelf provided with an upwardly projecting flange, at its outer edge, said shelf and
flange constituting a gutter which for convenience of reference is marked E.
This gutter extends from one side of the cup D, entirely around the base of the
jar B, to the opposite side of the cup D, as shown in Figure 1, and is partially filled
with free mercury.
A zinc plate F, is inserted in the jar A, its lower edge resting in the gutter E.

page_text: The plate is cylindrical in form, and is provided with a vertical opening or a slot in
one of its sides, through which the solution K, flows, and also for the reception of the
cup, D, as shown at E in Figure 1.
A stud projects from the upper edge of the said plate, through a hole d, in the
cover C; and to this stud is secured a screw-cap for the conducting wire i.
A carbon plate H, provided at its upper end with a stud e, which projects through a
hole in the cover C, is disposed in the porous jar B, the said stud being provided
with a screw cap 1, for the conducting wire k.
The porous cup B, is filled around the plate H, with granulated carbon and
manganese J.
The jar A is filled with an acidulated solution K, composed preferably of one part
of sulphuric acid and six parts of water.
The cup D is filled with sulphuric acid N, for feeding or reinforcing the solution K,
in the jar A.
The walls of the porous jar B, are perforated as shown at j, thereby permitting the
solution K, to freely enter the said jar and act upon the plate H, and also upon the
carbon and manganese J. The walls of the cup D being porous, the acid N, percolates
the same in sufficient quantities to feed or reinforce the solution K.
The free mercury t, in the channel E, serves to keep the zinc plate F, properly
amalgamated and thereby prevents its undue destruction by the action of the
acidulated solution K.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is
First. In a galvanic battery of the character described, the perforated porous jar B,
provided with the feeding cup D, and gutter E, constructed and arranged sub-
stantially as shown.
Second. In a galvanic battery of the character described, the jar A, provided with
the cover C, in combination with the porous jar B, provided with the cup D, and
gutter E, substantially as specified.
Third. In a galvanic battery of the character. described, the perforated porous
jar B, provided with the cup D, and gutter E, the containing jar A, provided with
the cover C, the cylindrical zinc plate F, standing in the gutter E; the carbon
plate H, disposed in the jar B; the acid N, disposed in the cup D; the acidulated
solution K, disposed in the jar A; the free mercury, t, disposed in the gutter E;
and carbon J, disposed in the jar B, all combined and arranged to operate sub-
stantially as set forth.
Fourth. In a galvanic battery of the character described, a perforated porous jar
provided with a gutter for containing free mercury, and with a cup for containing
a reinforcing acid, said cup and gutter being formed integral with the body of the
jar, and the gutter and cup disposed on the outer side of said body, the cup being
interposed between the ends of said gutter, substantially as shown and described.
Dated this 13th day of December 1887.
