do hereby declare the nature of this invention to be as follows:-
This Invention has for its object improvements in portable batteries for the.
production of electric light.
The improved battery consists of a vessel preferably of cylindrical form or it may
be rectangular; it is divided into two three four or other number of compartments
by partitions. The vessel stands upon a foot and projections on the bottom of the
vessel enter holes in the foot.
A metal stem fixed to the foot projects up through a central passage formed in the
vessel where the partitions meet in a boss at the centre.
The vessel receives a cover which is faced on the under side with india rubber.
The stem of the foot projects also up through a central hole in the cover.
To this cover the battery elements are fixed as hereinafter described.
A second or outer cover fits on over the first and this cover carries an electric
incandescent lamp.
In the centre of the outer cover which is of conical form there is a collar in which a
thumb nut is able to turn. The nut screws on to a thread cut upon the stem of the
foot and when tight it holds the parts all together, and the under cover in liquid tight
contact with the top of the vessel and its partitions.
When I lift the elements from the vessel the thumb nut meets a thread on the top
of stem and by screwing the thumb nut on this thread the elements are kept out
of the liquid.
The zinc elements of the battery consist of round rods having threads cut on their
upper ends which screw into nuts embedded in the under cover; they are notched at
either or both ends to receive a screw driver. When screwed home they make a
tight joint against the india rubber with which the under side of the cover is lined.
The liquid of the battery is thus effectually excluded from the joint. An india rubber
ring may be applied around the zinc to prevent the upper end being dissolved by
the liquid.

page_text: The carbons are held in clips having screw stems passing up into the cover and
receiving nuts. The clips are embedded in marine glue or like composition.
The elements are connected in series by wires embedded in the substance of the
under cover and closed in with marine glue or the like. The terminals are brought
to two nuts let into the under cover.
The outer cover is also clothed on its under side with india rubber; it carries the
electric lamp as already stated. The terminals of the lamp are taken to metallic nuts
let into the upper cover. The circuit is completed by the insertion of two screws;
each screw passes through one of the lamp terminal nuts in the upper cover and
enters one of the battery terminal nuts in the inner cover. The screws also join the
two covers together..
When the thumb nut is unscrewed from the stem of the foot the cover with the
elements can be lifted so as to remove the latter out of the liquid. The nut then can
be screwed on to another thread provided at the upper end of the stem, in such a
position that the cover is supported at a sufficient distance above the vessel.
Sometimes I make the battery vessel in two parts, a lower part subdivided by the
partitions and an upper part carrying the cover and elements.
The latter part fits over the former and the joint is made tight by an elastic ring.
Thus the vessel is telescopic and it can be elongated to raise the elements out of
the liquid or compressed to replace them in it. Nevertheless the vessel remains closed
liquid tight with the exception of a small vent provided for the escape of gas and to
which a cap is provided.

page_text: I, ALEXANDER SCHANSCHIEFF, of Gipsy Hill, in the County of Surrey, 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:-
:1!
This invention has for its object improvements in portable batteries for the production
of electric light.
The improved battery consists of a vessel preferably of cylindrical form or it may
be rectangular; it is divided into two three four or other number of compartments
by partitions. The vessel stands upon a foot and projections on the bottom of the
vessel enter holes in the foot.
A metal stem fixed to the foot projects up through a central passage formed in the
vessel where the partitions meet in a boss at the centre.
The vessel receives a cover which is faced on the under side with india rubber.
The stem of the foot projects also up through a central hole in the cover.
To this cover the battery clements are fixed as hereinafter described.
A second or outer cover fits on over the first and this cover carries an electric
incandescent lamp.
In the centre of the outer cover which is of conical form there is a collar in which
a thumb nut is able to turn. The nut screws on to a thread cut upon the stem of
the foot and when tight it holds the parts all together, and the under cover in liquid
tight contact with the top of the vessel and its partitions.
When I lift the elements from the vessel the thumb nut meets a thread on the top
of stem and by screwing the thumb nut on this thread the elements are kept out of
the liquid.
The zinc elements of the battery consist of round rods having threads cut on their
upper ends which screw into nuts embedded in the under cover: The nuts of one cell
are connected by wires embedded in the under cover to the two carbons of the next,
and the nuts of last cell are coupled with the lamp. The zines are notched at either
or both ends to receive a screw driver. When screwed home they make a tight joint
against the india rubber with which the under side of the cover is lined. The liquid
of the battery is thus effectually excluded from the joint. An india rubber ring may
be applied around the zinc to prevent the upper end being dissolved by the liquid.
The carbons are held in clips having screw stems passing up into the cover and
receiving nuts. The clips are embedded in marine glue or like composition.
The elements are connected in series by wires embedded in the substance of the
under cover and closed in with marine glue or the like. The terminals are brought
to two nuts let into the under cover.
The outer cover is also clothed on its under side with india rubber; it carries the
electric lamp as already stated. The terminals of the lamp are taken to metallic nuts

page_text: let into the upper cover. The circuit is completed by the insertion of two screws;
each screw passes through one of the lamp terminal nuts in the upper cover and
enters one of the battery terminal nuts in the inner cover. The screws also join the
two covers together.
When the thumb nut is unscrewed from the stem of the foot the cover with the
elements can be lifted so as to remove the latter out of the liquid. The nut then can
be screwed on another thread provided at the upper end of the stem, in such a
position that the cover is supported at a sufficient distance above the vessel.
Sometimes I make the battery vessel in two parts, a-lower part subdivided by the
partitions and an upper part carrying the cover and elements.
The latter part fits over the former and the joint is made tight by an elastic ring.
Thus the vessel is telescopic and it can be elongated to raise the elements out of the
liquid or compressed to replace them in it. Nevertheless the vessel remains closed
liquid tight with the exception of a small vent provided for the escape of gas and to
which a cap is provided.
In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of a battery lamp of this construction.
Figure 2 is a vertical section of the same.
Figure 3 is a plan.
Figure 4 is a horizontal section through the battery elements.
Figure 5 is a plan of the inner cover."
Figure 6 is a section of a portion of the inner cover on the line c in Figure 5.
a is the vessel divided by radial partitions, b is the foot on which it stands; is a
stem fixed into the foot, c is the inner cover carrying the battery elements; it is made
preferably of vulcanite. d is the outer cover of wood on which the glow lamp with
its outer covering glass e is mounted.
The foot is provided with a pin 2 which enters a corresponding recess in the
bottom of the vessel a to prevent it turning. The inner cover c is provided on its
inner side with a face c¹ of vulcanised india rubber, the edges of this bear upon the
upper edge of the vessel a and make a liquid tight joint. are the carbon elements,
they are held by rivets in clips f¹¹ (see Figure 6) and these clips have stems f³ passing
up into holes in the cover c and receiving nuts f³ which are sunk into recesses.
clips ffare coated with marine glue. g g are the zinc elements, they have secrew
stems which screw into nuts g¹ glet into the cover on the outer side. 92 g² are rings
of vulcanised india rubber placed around the zincs to prevent their upper ends being
dissolved. At h h two small nuts are let into the cover c on the inner side and these
serve to secure the outer cover d.
The
One of the nuts is the carbon terminal of the battery and the other is the zine
terminal.
The connections are made by wires laid in grooves on the under side of the cover c,
the grooves are filled over the connecting wires with marine glue and the india
rubber c¹ covers them so as to prevent any access of the battery solution to the con-
nections. The outer cover d has a socket of the usual sort fixed upon it in which the
glow lamp is carried and for additional security the glass e is provided over the glow
lamp. is a collar fixed to the cover d by screws from the underside and k is a nut
held in this collar but able to turn. The screw stem ¹ passes through this nut and
by screwing the nut on to the lower thread on the stem at 6x the battery is effectually
closed. The lamp terminals are connected by wires laid in grooves on the inner face
of the cover d to metal ferrules let into the cover at 11. These ferrules receive
screws m m which pass down through them into the nuts and thus electrical
connection with the lamp is established. The battery can be put out of action by
unscrewing the nut k and lifting the two covers c and d which are now held together
by the screws m. Then by screwing the nut on to the thread B at the upper end of

page_text: the stem the covers are supported with the battery elements out of the liquid. It
is convenient to make the cover in two parts as then the attachments are concealed
and yet readily accessible but the cover may be made in one piece or its parts may be
permanently connected.
In place of forming screw threads upon the stem I can provide pins or projections
upon it, one immediately over the cover and the other near the top of the stem b'.
The nut or rotating part k is then slotted in such a way as to enable it to pass the
pins or projections upon the stem. The part k is also provided with inclines on its
upper surface. Figure 7 shows an elevation of these parts and Figure 8 is a plan of
the nut or part k. When the cover is in its place closing the vessel a the part k on
being turned acts by its incline upon the lower pin upon the stem b₁ and forces the
cover down so as to make a secure joint. When the cover is unfastened and lifted the nut
or part k passes above the upper pin upon the stem and being then turned it rests on
the pin and supports the cover with the battery elements out of the liquid.
Figure 9 shows in section a lamp battery in which the cell or vessel is made
telescopic o is the upper part of the vessel; it is cylindrical and open at both ends;
at its upper part it receives the cover p upon which are the battery elements lamp and
other parts as already described. The cover may be fixed in place on the part o in
any convenient manner, is the lower part of the telescopic vessel, it also is cylindrical
in the body, but it is closed at the lower end and divided by partitions in the same
way as in the battery lamp previously described. r is a round ring of vulcanised
india rubber interposed between the parts o and q making a tight joint but allowing
the parts to move telescopically, the india rubber ring rolling between them.
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 what I
claim is :-
1. A lamp battery substantially as described consisting of a vessel divided by
partitions into cells; a cover in one or more parts carrying the elements and a
glow lamp; a sten passing through the centre of the cover and connecting it with
the vessel; and a nut or fastening on the stem holding the cover in place and
closing the battery.
2. A lamp battery substantially as described consisting of a vessel divided by
partitions into cells; a cover in one or more parts faced on its inner side with india
rubber closing the vessel; battery elements attached to the cover; connecting wires
between the elements and to the battery terminals laid in grooves in the cover and
between it and the india rubber face.
3. The method substantially as described of connecting the zinc elements by forming
a screw-thread upon them and screwing them into nuts inserted into the cover of
the battery.
4. A lamp battery with telescope container or vessel substantially as described.
5. Apparatus substantially as described and represented by the annexed drawings.
