declare the nature of this Invention to be as follows:-
This Invention has for its object to provide a battery simple in construction
occupying but a small space in comparison with its power and readily and economically
regenerated or put into a condition for renewed work after it has become exhausted.
The Invention relates to batteries which may be compactly arranged as far as the
general disposition of the elements and adjuncts adapted to a single liquid battery are
concerned after the manner illustrated and described under the Patent 11521 dated
21st August 1884 granted to John Henry Johnson as a communication from Philipp
George Skrivanow but this present Invention relates to batteries whereof the negative
element is coated with or holds chloride of silver but we may use instead peroxide of
Silver. When we use chloride of Silver a suitable support therefor is carbon but
when we use peroxide of Silver we prefer to make the support of silver or platinum.
The positive element may be of zinc of tin or of iron using by preference zinc when
we use peroxide of Silver for the opposite element. The electrolyte for the elements
is either a potassic or sodic hydrate but when the negative element carries chloride of
silver and the positive element is tin we prefer to use dilute hydrochloric acid as the
electrolyte.
In order to make the battery portable and readily accessible we prefer to fix all the
negative elements to a single plate or carrier so that they may all be removed at once
from the battery This plate or carrier is preferable of insulite or vulcanite and forms
a cover for the cells and it may be held in position by a metal cover fastened over it so
that the battery is thereby hermetically sealed. The connections required to couple up
the cells are arranged so that the act of putting on the cover couples up the cells. The
lamp may be placed in the metal cover to admit also of the contacts for the circuit
therethrough being made on fastening on the cover.

page_text: In order to regenerate the negative elements we remove the said elements from the
battery and place them in a bath of hydrochloric acid or of chloride of sodium or
potassium or other soluble chloride or the bath may consist of, or contain, the spent
liquor of the battery. Through this bath whilst the elements to be regenerated are
immersed therein we pass an electric current and when the spent liquor is used as the
bath we recover by that means the metal in solution therein whilst at the same time
we regenerate or reconvert the elements and claim an electrolyte fit for re-use in
the battery.
Where a circular form of the lamp is desired the chloride or oxide elements may
be arranged in pairs with the zincs surrounding them either by being made as two
cylinders or in S form with a chloride or oxide element in each loop of the S. These
pairs of elements are coupled together and are situated in one compartment or cell
of the battery of which compartments or cells there are preferably three separated by
radial divisions extending from a central post. The cover of the battery is made of a
circular disc of insulating material to which the elements are attached the one set
terminating in a spring which bears upon a metal cover placed over the insulating
cover. This metal cover carries the lamp which has an insulating material between it
and the metallic lamp stem. The other set of electrodes terminates in a contact piece
which when the metal cover is put in place bears on a spring contact plunger in the
lamp stem. The terminal wires of the filament of the lamp are respectively in
electrical contact with the said spring contact plunger and the metallic cover which
bears on the spring to which one set of elements is connected. By this means when
the metallic cover is put on and forced down the lamp circuit is completed and the
lamp lighted. A convenient mode of attaching the metal cover to the battery is to
provide it with catch pieces sliding down vertical grooves at the top of the battery
and then by a rotary motion caused to take under inclined projections by which the
metal cover is drawn down to make the contacts. The metal cover may be locked to
the battery by holes in the rims of each arranged after the manner of the divisions of
a vernier and scale so that a slight movement brings the holes opposite each other.

We THE NEW PORTABLE ELECTRIC LAMP AND POWER SYNDICATE COMPANY
Limited of 41 Coleman Street in the City of London and DAVID URQUHART of 4 The
Sanctuary in the City of Westminster Electrical Engineer and BENJAMIN NICHOLSON
of The Torrs South Norwood Park in the County of Surrey Gentleman, 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 :-
This Invention has for its object to provide a battery simple in construction
occupying but a small space in comparison with its power and readily and
economically regenerated or put into a condition for renewed work after it has
become exhausted.
The Invention relates to batteries which may be compactly arranged as far as the
general disposition of the elements and adjuncts adapted to a single liquid battery are
concerned after the manner illustrated and described under the Patent 11,521 dated
21st August 1884 granted to John Henry Johnson as a communication from Philipp
George Skrivanow but this present Invention relates to batteries whereof the negative
element is coated with or holds chloride of Silver but we may use instead peroxide of
Silver. When we use chloride of silver a suitable support therefor is carbon but when
we use peroxide of Silver we prefer to make the support of silver or platinum. The
positive element may be of zinc of tin or of iron using by preference zinc when we
use peroxide of silver for the opposite element.
The electrolyte for the elements is either a potassic or sodic hydrate but when the
negative element carries chloride of silver and the positive element is tin we use dilute
hydrochloric acid as the electrolyte.
In order to make the battery portable and readily accessible we prefer to fix all the
negative elements (positive pole plates) to a single plate or carrier so that they may
all be removed at once from the battery. This plate or carrier is preferable of insulite
or vulcanite and forms a cover for the cells and it may be held in position by a metal
cover fastened over it so that the battery is thereby hermetically sealed. The cover
which carries the negative elements also carries contact pieces which make the
connection with the positive elements (negative pole plates) when the cover is put in
place so that the act of putting on the cover couples up the cells. The lamp may be
placed in the metal cover to admit also of the contacts for the circuits through the
lamp being made on fastening on the cover.
In order to regenerate the negative elements we remove the said elements from the
battery and place them in a bath of hydrochloric acid or of chloride of sodium or
Potassium or other soluble chloride or the bath may consist of or contain the spent
liquor of the battery. Through this bath whilst the elements to be regenerated are
immersed therein we pass an electric current using what were the negative elements

bath being any conductor usually employed in analogous processes. When the spent
liquor is used as the bath we recover by that means the metal in solution therein
whilst at the same time we regenerate or reconvert the elements and obtain an
electrolyte fit for reuse in the battery.
use.
Where a circular form of the lamp is desired the chloride or oxide elements may be
arranged in pairs with the zincs surrounding them either by being made as two
Cylinders or in S form with a chloride or oxide element in each loop of the S. These
pairs of elements are coupled together and are situated in one compartment or cell of
the battery of which compartments or cells there are preferably three separated by
radial divisions extending from a central post. The cover of the battery is made of a
circular disc of insulating material to which the elements are attached the one set
terminating in a spring which bears against a metal cover placed over the insulating
cover. This metal cover carries the lamp which has an insulating material between
it and the metallic lamp stem. The other set of electrodes terminates in a contact
piece which when the metal cover is put in place bears against a spring contact
plunger in the lamp stem. The terminal wires of the filament of the lamp are
respectively in electrical contact with the said spring contact plunger and the metallic
cover which bears on the spring to which one set of elements is connected. By this
means when the metallic cover is put on and forced down the lamp circuit is completed
and the lamp lighted. A convenient mode of attaching the metal cover to the battery
is to provide it with catch pieces sliding down vertical grooves at the top of the
battery and then by a rotary motion caused to take under inclined projections by
which the metal cover is drawn down to make the contacts. The metal cover may be
locked to the battery by holes in the rims of each arranged after the manner of the
divisions of a vernier and scale so that a slight movement brings the holes opposite
each other. The accompanying drawing represents as an example a circular portable
electric lamp constructed according to this Invention suitable for Miners
Figure 1 is an elevation of the upper portion of the lamp. Figure a plan with the
cover removed. Figure 3 a sectional elevation and Figure 4 a horizontal section.
A is a metal frame consisting of a base of thin metal connected by bars or strips y
to a ring surrounding the upper part of the battery B thereby constituting a casing
or support for the said battery. The battery is preferably made of vulcanite or like
material and is divided by radial partitions into three cells (each containing a set of
two pairs of elements the zinc or positive elements D being preferably S shaped and
containing in each loop thereof the oxide or negative elements E. These elements
are carried by a disc F of vulcanite or other suitable insulating material forming the
cover to the battery. The two negative elements in each cell are electrically connected
together by a strip G and the several elements are electrically connected in series as
is well understood. A spring H connected to one of the strips G constitutes the
positive terminal of the battery whilst the other terminal consists of a block I secured
to the centre of the disc F and electrically connected to one of the positive elements
by a wire i passing through a tube of vulcanite or the like secured to the cover F
which tube is provided with a slot in which a strip w from the positive element enters
and in which it is in contact with the wire i leading to the block I. The positive and
negative elements are connected inseries by a similar arrangement the wires ³ entering
the tubes of vulcanite or the like where they come into contact with the strips to
from the positive elements the other ends of the wires being electrically connected to
the strips G. The illuminating portion of the lamp is fitted in a metal socket K to
which one of the terminal wires of the illuminating filament is connected the other
terminal wire of the said filament being connected to a plug L fitted in the socket K
but insulated therefrom by vulcanite or other suitable material. Through the plug L
passes the stem M of a spring plunger which when the lamp is in use makes contact
with the terminal I of the battery the contact with the other terminal to complete the
circuit through the lamp being made by the spring H and a metal Collar N screwed
into or onto the metallic cap or cover of the lamp and in one with or electrically
connected to the socket K.

page_text: The cover is secured to the frame A of the lamp by lips or projections P
formed on the upper ends of the bars or strips y of the frame passed through notches
or openings a in the rim b attached to or formed on the cover and engaging with
another ring fitted to turn on the cover so as to engage beneath the lips P. The
ring is provided with inclines v₁ on the upper surface so that by turning the ring
beneath the lips or projections P the said inclines forcibly press down the cover
towards the disc F without rotating the said cover between which cover and the disc F
is interposed an india rubber packing ring Q so as to ensure a liquid tight joint at
that
part.
When the cover O is forced down to the extent required to bring the terminals HN
and I M into contact the lamp will be lighted and it may be maintained in this
position by passing a bolt or the loop of a padlock through holes d provided for the
purpose in the rings 6 and v near the edge of the cap or cover O as shewn by dotted
lines in Figure 1. The bulb of the lamp is enclosed in an outer globe u secured to
the cover by the disc N as shewn in Figure 3 and a hook R constituting a handle to
the lamp is connected to the cover by wires S which serve as a cage to protect the
illuminating portion of the lamp from injury.
