MARK BAILEY Hollies Lodge, Clarence Road, Wood Green London N. Electrician
and JOHN WARNER 21 Osborn Street Whitechapel, London E. Ironfounder, 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:
Our Invention consists in an Improved construction of secondary, or polarization
battery formed in the manner herein after described, and the combination therewith
of an electric lamp suitable for mixing or other purposes.
Our object is to obtain within as small a space as possible a store, or supply of
energy capable of sustaining a lamp at its full light giving capacity during the
ordinary working shift; and to enable exhausted plates to be promptly removed and
replaced. The annexed drawing and explanation will make clear the manner in which
we carry our invention into effect.
Fig. 1, is a sectional elevation shewing our improved method of arranging the
plates and cells.
Fig. 2, is a side elevation of the form of plate we employ.
Fig. 3 an elevation of the battery and lamp shewing general arrangement.
Fig. 4, enlarged view of plate shewing selvage, or bound edge.
We prefer to employ narrow glass, porcelain, or ebonite cells A A; the elements B B,
being so arranged or folded over the sides of contiguous cells as at C, as to help
to hold them together, and so that one part of the same plate is an anode in one cell,
and a cathode in the other. We construct our plates of lead wire closely woven into
a ribbon, mat, or mesh, having a selvage or bound edge D; the size of wire varying
with the area & weight of the plate employed. A series of these plain woven plates are
now set up as shewn in Figs. 1 and 3, the cells being filled with sulphuric acid and
water, and are then formed upon the Planté system, either by the current derived
from a battery of higher electro-motive force; or by a suitable dynamo machine.
When the plates are fully formed, we enclose the cells in a wooden or other box E,
furnished with a strap or handle G, and upon any convenient part of the box we
mount a lampf, which is suitably connected to the battery.

page_text: We also provide means for recharging the cells by means of terminals formed in
the material of the box as at H H, these are sunk within the wood, and when the
charging takes place, plugs are inserted, and connected to the machine or battery.
The plates can be woven, and afterwards formed in any suitable length; and then cut
to suit the size of battery. The arrangement described enables us to obtain a very
large flexible, and coherent surface free from the defects common to plates formed
from an adherent or added material.
Having now described our Invention, and the manner in which we carry the same
into effect we would wish it understood that we are aware that plates formed of a
woven material have been employed to sustain an added substance, subsequently
treated so
as to obtain the conditions needful for a secondary battery; to such
however we lay no claim; what we believe to be novel and desire to have secured
to us is,
1st. An Improved Secondary Battery constructed, chemically formed, and con-
nected to an incandescent lamp suitable for mining or other purposes substantially as
set forth.
2nd. The method of constructing the elements employed in the above combination
by means of wire consisting of lead woven into a ribbon, mat, or mesh, having a
bound edge or selvage, said elements being formed upon the Planté system in the
manner described.
3rd. In an Improved Secondary battery combined with a lamp as described, the
method of suspending the elements so as to avoid all joints and connections, and so
that one and the same element is an anode in one cell, but cathode in the contiguous
one, the arrangement described also assisting to hold contiguous cells in contact, as
herein set forth.
