1, WILLIAM EDWARD TEALE of Sindsley House Swinton in the County of
Lancaster Lamp Manufacturer do hereby declare the nature of this invention to be
as follows:-
This invention is an improvement upon an invention for which Letters Patent
No. 4888 bearing date 30th November 1878 were granted to me and the object
of the present invention is to simplify and improve such lamp and to adapt it
more particularly to the burning of heavy hydro-carbon oils.
The oil cell or cistern I make in metal and by preference of a cylindrical or
conical form having a wick tube projecting upwards from the centre of the top of
the same, such tube being screwed on the outside. The feeding aperture is provided
inside with a tube which is turned or bent sideways at a right angle or other con-
venient angle, so as to prevent the oil from flowing out if the lamp should be tilted
or upset. There is also in the top a small vent pipe for the escape of the air whilst
filling the cistern and the pipe is carried down and bent sideways for the same
purpose. I prefer to place a piece or pieces of sponge in the cell to prevent the oil
swisbing" about, and I employ a double wick; that is to say I have a
permanent wick which is always in the oil but only extends a certain distance up the
wick tube and in the top of the latter I place a small plug of cotton wool which will
require to be renewed whenever it becomes encrusted.
from <
Upon the wick tube I screw another tube which serves to regulate the height of
the flame, and at the same time carries a metal dome or cone which regulates the
supply of air to the flame, the lower side of this dome or cone being perforated for
the admission of the air.
The lower part of the body of the lamp is in the form of a cap which fits over
the upper part of the oil cell and is attached to the dome or cone in the following
manner.
The latter is provided with two lugs in which are fixed two headed pins. In the
upper part of the cap are two corresponding slots larger at one end than at the other,
one of which is provided with a spring partly covering its slot.

page_text: To attach the oil cell and the body of the lamp together, these pins are forced
through the larger part of the slots, one of them raising the spring; the cap (or
the cell) is then partially turned and the spring slips off the head of the pin and
comes behind it, so as to lock it and prevent it from being removed.
This spring cannot be released until the oil cell has been unscrewed. The upper
part of the body of the lamp is in the form of a flat ring with a conical chimney
projecting from the top and it is connected to the lower part by means of three stout
wires or pillars inside which is a glass cylinder to protect the flame. One of these
pillars is removable so that a fresh glass can be inserted when required, and the lamp
is provided with a convenient non conducting handle.
The top plate and the bottom run of the body are perforated for the admission of
air to the interior of the lamp.
In lighting the lamp, the cell having been charged with oil, the dome is removed
from the body of the lamp (by pressing the spring) and then screwed onto the top of
the wick tube, a light is then applied to the wick and the body of the lamp affixed by
passing the headed pins through the larger end of the slots in the cap and then a
slight turn removes the pin from under the spring which falls and locks the lamp.
The height of the flame is regulated by unscrewing or screwing the oil cell which
lowers or raises the wick tube inside the extinguishing tube attached to the cone.
The bottom of the oil cell is dished in the centre so that the permanent wick is
always supplied so long as the cell contains any oil at all.

Improvements in Lamps for Domestic and other Purposes.
I WILLIAM EDWARD TEALE of Sindsley House Swinton in the County of
Lancaster Lamp Manufacturer 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 is an improvement upon an invention for which Letters Patent
No. 4888 bearing date 30th November 1878 were granted to me, and the object
of the present invention is to simplify and improve such lamp, and to adapt it
more particularly to the burning of heavy hydrocarbon oils.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the sheet
of drawings hereunto annexed and the following explanation thereof.
Fig. 1. is a plan view of the oil cell. Fig. 2 a partial plan of the upper part
of the body of the lamp. Fig. 3 a plan of the lower part of the body of the
lamp and oil cell, the pillars and handle being in section taken through about the
line A-B (in Fig. 4). Fig. 4 is a side elevation of the lamp complete. Fig. 5 a
section of the lower part of the body and Fig. 6 a section of the oil cell, wick
tube and dome.
The oil cell or cistern a I make in metal and by preference of a cylindrical or
conical form having a wick tube b projecting upwards from the centre of the top of
the same, such tube being screwed on the outside. The feeding aperture c is provided
inside with a tube d which is turned or bent sideways at a right angle, or other
convenient angle, so as to prevent the oil from flowing out if the lamp should be
tilted or upset. There is also in the top a small vent pipe e for the escape of
the air whilst filling the cistern a and this pipe is carried down and bent sideways
for the same purpose.
"
I prefer to place a piece or pieces of sponge in the cell to prevent the oil from
'swishing' "about and I employ a double wick; that is to say I have a permanent
wick (see Fig. 6) which is always in the oil but only extends a certain distance up
the wick tube b and in the top of the latter I place a small plug of cotton wool 1
which will require to be renewed whenever it becomes encrusted.
Upon the wick tube b I screw another tube g which serves to regulate the height
of the flame, and at the same time carries a metal dome or cone h which regulates
the supply of air to the flame, the lower side of this dome or cone being perforated
for the admission of the air, as shown at Fig. 6.
The lower part of the body of the lamp (see Fig. 5) is in the form of a cap which
fits over the upper part a' of the oil cell a and is attached to the dome or cone h in
the following manner.
The latter is provided with two lugs h¹ see
headed pins kk. In the upper part of the
at one end than at the other, one of which is
Figs. 3 and 6 in which are fixed two
cap i are two corresponding slots larger
provided with a spring I partly covering

page_text: its slot. To attach the oil cell a and the body i of the lamp together, these pins k
are forced through the larger part of the slots, one of them raising the spring; the
cap i (or the cell a) is then partially turned and the spring 1 slips off the head of the
pink and comes in front of it so as to lock it and prevent it from being removed.
-
This spring cannot be released until the oil cell a has been unscrewed.
The upper part of the body of the lamp (see Figs. 2 and 4) is in the form of a
flat ring or plate m with a conical chimney n projecting from the top and it is con-
nected to the lower part by means of three stout wires or pillars o inside which is a
glass cylinder p to protect the flame.
i
One of these pillars o¹ see Fig. 4 is removable by unscrewing so that a fresh
glass p can be inserted when required, and the lamp is provided with a convenient
handle g.
The top plate m and the bottom rim of the body are perforated for the admission
of air to the interior of the lamp.
In lighting the lamp, the cell a having been charged with oil, the dome h is
removed from the body of the lamp (by pressing the spring button (*) and then
screwed onto the top of the wick tube b.
A light is then applied to the wick f¹, and the body i of the lamp affixed by passing
the headed pins k, k¹ through the larger end of the slots in the i and then a slight
cap
turn removes the pin k¹ from under the spring which falls and locks the lamp.
The height of the flame is regulated by screwing or unscrewing the oil cell a which
raises or lowers the wick tube b inside the extinguishing tube g attached to the
cone h.
:
The bottom all of the oil cell (see Fig. 6) is dished in the centre so that the
permanent wickfis always supplied so long as the cell a contains any oil at all.
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: -
The general construction and arrangement of parts constituting a safety lamp for
domestic and other purposes substantially as herein before described and illustrated by
the annexed drawings.
