page_text: WILLIAM KINGSLAND 49 Cambridge Road Gunnersbury W. Electrical Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of constructing a secondary battery
whereby the same may be used for a great variety of purposes such for instance as
electric-bell, telegraph or telephone work, where it is necessary that the work of the
cell should be extended over as long a time as possible without attention, and
" or from the necessity
consequently that the battery should be free from "local action
of recharging it at comparatively frequent intervals.
In order to effect this 1 employ a negative element or anode consisting wholly or
mainly of peroxide of lead in a hard, dense, compressed or agglomerate condition,
and not in contact with any oxidysable metal, and in conjunction with this element 1
employ a positive element or cathode of zinc, and I prepare this zinc element so as
to resist "local action" by first amalgamating it with mercury, and then depositing
on it electrolytically a coating of zinc, or may deposit the zinc on some other metal
such for instance as lead.
The peroxide of lead and the zinc elements are mounted in a suitable containing
cell of glass or other material, and the cell may advantageously be sealed in order to
prevent the evaporation or spilling of the electrolyte, which latter may advantageously
consist of a dilute solution of sulphuric acid.

page_text: I, WILLIAM KINGSLAND, of 49 Cambridge Road, Gunnersbury in the County of
Middlesex Electrician, 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 an improved method of constructing a secondary battery
whereby the same may be used for a great variety of purposes such for instance as
electric bell, telegraph, or telephone work, where it is necessary that the work of the
cell should be extended over as long a time as possible without attention and
consequently that the battery should be free from "local action
,, or from the necessity
of recharging it at comparatively frequent intervals.
In order to effect this I employ a negative element or anode consisting wholly or
mainly of peroxide of lead in a bard, dense, compressed or agglomerate condition
not in contact with any oxidizable metal, the said anode being preferably made up
and provided with contact strips as described in the specification of patent granted to
myself No. 5867 dated 22 April 1887. In conjunction with this element I employ a
positive element or cathode of zinc, and I prepare this zinc element so as to resist
"local action" by first amalgamating it with mercury and then depositing on it
electrolytically a coating of zinc, or I may deposit the zinc on some other metal such
for instance as lead; the object in every case being to work with the pure
deposited zinc.
The peroxide of lead and the zinc elements are mounted in a suitable containing cell
of glass or other material and the cell may advantageously be sealed in order to
prevent the evaporation or spilling of the electrolyte, which latter may advantageously
consist of a dilute solution of sulphuric acid.
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 I am aware that it has
been proposed to use in secondary batteries an anode composed of peroxide of lead
not in contact with any oxidizable metal, I lay no claim to such an anode per se, but
what I claim is :
1. In secondary batteries an anode or negative element, composed of solid peroxide
of lead in combination with a cathode or positive element prepared by the electrolytic
deposition of zinc, on a zinc, lead, or other base, whereby local action is prevented,

page_text: 2. In secondary batteries, a cathode or positive element prepared by electrolytic
deposition of zinc, on a zinc, lead, or other base, in combination with an anode or
negative element composed of solid or agglomerate peroxide of lead made up or fitted
as described in specification of patent No. 5867 of 1887 hereinbefore referred to, all
constructed arranged and acting substantially as and for the purposes herein
set forth.
