Improvements in Lamps and Lamp Stoves.
We, ELIZA RIPPINGILLE, Lamp and Stove Manufacturer, and WILLIAM
PORTER, Foreman, both of The Albion Lamp Company, Aston Brook Lamp
Works, Birmingham, do hereby declare the nature of this invention to be as
follows:-
The invention relates to that description of lamp or lamp stove in which the
burner has two wick tubes for flat wicks side by side and a cone with only one
opening through which the two flames pass.
We will first describe our invention as applied to that class of lamp or oil stove
in which the oil tank and burner, that is to say, the lamp, is slidden into position
underneath its chimney.
Heretofore the tanks of such lamps have rested upon the bottom plate of the stove,
or have been supported on ledges with their bottoms close to the surface on which
the stove is placed, and no efficient supply of air has been afforded between the two
wicks.
The present invention consists in supporting the tank at a suitable height above
the supporting surface, either by the addition of feet to the tank or in other suitable
way, and in forming a rectangular air chamber passing through the tank, preferably
flush with the bottom of the latter, and extending upwards some distance above the
top, such air chamber being open at the bottom and having a perforated diaphragm
at or near its upper end. This air chamber is of size to fit exactly the space
between the wick tubes or a tube fixed within such space, and the upper part thereof
serves as a guide to the burner. The burner is provided with the ordinary
perforated diaphragm, through which the air passes to the space within the cone
and to the exterior of the wicks, and the cone has only one opening through which
both flames pass separated from each other by the intermediate air current.
The invention is also applicable to such description of lamp stove or lamp in which
the tank and burner are dropped into an external case.
The perforated diaphragm at or near the upper end of the intermediate air
chamber may be flat, concave, convex, or of other desired shape.
The above construction is also applicable to oil lamps used only for lighting
purposes, and in either case the intermediate air tube may fit the space between the
wick tubes or a tube inserted in such space. In some cases the wick tubes may
extend above the intermediate air chamber or tube, which latter may extend below
the wick tubes and at its upper end open into a basket surrounding the wick tubes
and supplying the air to the space between and around the latter. In any case
the burner has its lower part provided with a slightly conical or tapered fitting to
fit a correspondingly slightly comical or inclined socket formed on the top of the tank
around the central air tube or chamber.

page_text: We, ELIZA THORPE, formerly ELIZA RIPPINGILLE, Lamp and Stove Manufac-
turer. and WILLIAM PORTER, Forenian, both of The Albion Lamp Company, Aston
Brook Lamp Works, Birmingham, 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:—
The invention relates to that description of lamp or. lamp stove in which the
burner has two wick tubes for flat wicks side by side and a cone through which the
two flames pass.
Heretofore the tanks of such lamps as are slidden into position in the base. of an
oil stove have rested upon the bottom plate of the stove or have been supported
upon ledges with their bottoms close to the surface on which the stove is placed,
and no efficient supply of air has been afforded between the two wicks.
The present invention consists in supporting the tank at a suitable height above
the supporting surface either by the addition of feet to the tank or in other suitable
way, and in forming a rectangular air chamber passing through the tank preferably
flush with the bottom of the latter and extending upwards some distance above the
top, such air chamber being open at the bottom and having a perforated diaphragm
at or near its upper end. This air chamber is of size to fit exactly the space between
the wick tubes or a tube fixed within such space, and the upper part thereof serves
as a guide to the burner. The burner is provided with the ordinary perforated
diaphragm, through which the air passes to the space within the cone and to the
exterior of the wicks.
In some cases the cone has only one opening, through which
both flames pass, in which cases the flames are separated from each other by the
intermediate air current.
The invention is also applicable to such description of lamp stove or lamp
in which the tank and burner are dropped into an external case.
The perforated diaphragm at or near the upper end of the intermediate air
chamber may be flat, concave, convex, or of other desired shape.
The above construction is also applicable to oil lamps used only for lighting
purposes, and in either case the intermediate air tube may fit the space between the
wick tubes or a tube inserted in such space. In some cases the wick tubes may
extend above the intermediate air chamber or tube, which latter may extend below
the wick tubes and, at its upper end, open into a basket surrounding the wick tubes
and supplying the air to the space between and around the latter. In any case the
burner has its lower part provided with a slightly conical or tapered fitting to fit:a
correspondingly slightly conical or inclined socket formed on the top of the tank
around the central air tube or chamber.
The invention is illustrated in the accompanying drawings, in which:-
Fig. 1 is a vertical cross section and Fig. 2 is a plan of the tank and burner of a
lamp stove, and Fig. 3 is a part side view and Fig. 4 is an end view of a perforated
air diffuser for the central draft.
Fig. 5 is an elevation partly in section and Fig. 6 is a plan of the tank. and burner
of a lamp stove showing slight modifications, and Fig. 7 is a vertical section and
Fig. 8 is a plan of a lamp burner used only for lighting purposes.
In all the figures like parts are indicated by similar letters-of reference.
We will first describe the construction shown at Figs. 1 to 4.
a is the oil tank, the bottom of which is supported at some distance above the
bottom plate of the stove or other supporting surface by means of perforated
downwardly extending flanges a' forming continuations of the tank sides; to the
centre of the tank bottom is fixed a rectangular air tube a², which is open at both
ends so that air may enter at the bottom and pass out at the upper end to supply

page_text: air to the inner surfaces of the flames. The burner has two wick tubes bb, wick-
raising pinions ec, a perforated diaphragm or basket d, a seat e for the cone f, and
a slightly tapered fitting 9 to fit a correspondingly inclined socket formed in the
burner fitting a fixed to the tank top. The parts of the burner and burner fitting
above described are well known and form no part of our present invention. The
inner sides of the wick tubes and connecting plates fixed across the ends of the
latter form a rectangular air tube which fits over the air tube a³ and serves to
guide the burner correctly to its seat. The tube a does not rise quite to the top-
of the wick tubes, but a short tube h, whose upper end 1 level with the tops of the
wick tubes, rests on the top of the tube a², and such tube his surmounted by a
rectangular head or diaphragm perforated on its sides, ends and top. In this
construction the cone has only one opening through which both flames pass. It
will be seen that, in addition to the ordinary supply of air passing through the
diaphragm or basket d and supplied mainly to the exterior of the flames, there is a
central air current which enters the bottom of the tube a³, passes up between the
wick tubes and is distributed to the inner sides of the flames by the perforated head
or diaphragm . The lamp above described is for use with an oil stove and is
slidden into positiou in the base of the stove.
The arrangement shown at Figs. 5 and 6 is very similar to that above described
with the following exceptions, namely, instead of supporting the bottom of the
tank a above its supporting surface by perforated flanges a', it is so supported by
feet a; the air tube a' instead of rising above the top of the tank a, terininates on
a level therewith; the central air tube of the burner instead of being formed by
the inner sides of the wick tubes and plates fixed across the end of the latter, is a
separate tube i fixed to the burner between the wick tubes; such tube i descends
below the bottoms of the wick tubes b, fits inside the air tube a² and terminates
at its upper end below the tops of the wick tubes within the space between the
diaphragin d and an upper diaphragm j; also the cone f has two slits or openings
therein, one for each flame, instead of only one as in the previously described
arrangement, and the perforated head or diaphragm is replaced by the upper
diaphragm above referred to. In this case however a central air current is
supplied to the space between the wicks through the tube a², and a tube between
the wick tubes fits the tube a' and guides the burner correctly to its seat, as in the
arrangement described with respect to Figs.
to 4. The lamp shown at Figs. 5
and 6 has a chimney hinged to the pin & and a seat for culinary vessels at the top
of such chimney as is well understood. The seat e for the cone and chimney is
also hinged to the pin k; the diaphragm rests loosely on the seat e and fits loosely
the wick tubes b. Thus, in order to enable the burner to be removed, the chimney
and its seat e with the diaphragm jis first turned back on the pin k, when the
burner can be lifted vertically from its seat a³. The cone and chimney seat e is
provided with legs e¹ which rest on the burner fitting and assist in securing it in
place.
The lamp burner shown at Figs. 7 and 8 has a separate central air tube i, as in
Figs. 5 and 6, terminating at its upper end a little below the diaphragm ), but
terminating at its lower end at or near the bottom plate of the fitting y, as in
Fig. 1. The cone f has two slits or openings for the flames, as in Fig. 5, and the
air tube a² of the tank a rises above the top of such tank, also as in Fig. 1. The
body of the burner shown in Figs. 7 and 8 is circular, as is common for ordinary
lamp burners. In this example a central air current is supplied between the wick
tubes, and the burner is correctly guided to its seat by the tube i fitting the tube a³,
as described with respect to Figs. 1 to 6.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In oil lamps and stoves, the combination with an oil tank (a) and two flat
wicks contained in wick tubes (bb), of the air chamber (a²) and tube (a²), which

page_text: tube (a2) fits between the wick tubes (bb) and is fitted with the perforated
cap (¹), all constructed and arranged for the purposes hereinbefore set forth and
as illustrated in Figs. 1, 2, 3, 4.
2. In oil lamps and stoves, the combination with an oil tank (a) and two flat
wicks contained in wick tubes (bb), of the supports (a' a¹), the air tube (a) into
which fits the inner air tube (i) fastened to the wick tubes (66), the diaphragms (d d
and), and the double cone (f), all constructed and arranged for the purposes
herein before set forth and as illustrated in Figs. 5 and 6.
3. In oil lamps, the combination with an oil tank (a) and two flat wicks contained
in wick tubes (6 b), of the air tube (a) fitting into another air tube (1) fastened to
the wick tubes (6 b), the diaphragms (d d and j j), and the double cone (f), all
constructed and arranged for the purposes herein before set forth and as illustrated
in Figs. 7 and 8.
