Improvements in Lamps and Lamp Stoves.
We, ELIZA THORPE, formerly ELIZA RIPPINGILLE, Lamp and Stove
Manufacturer, and WILLIAM PORTER, Forenian, 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 class of lamp or lamp stove in which two or more
flat wicks are mounted parallel to each other and a central or intermediate air
supply is provided between the wicks, and the invention consists of novel modes of
construction of such class of lamps and lamp stoves.
In applying the present invention to lamps or lamp stoves in which the air
supply between the wick tubes is obtained through a tube passing through the oil
tank and the burner is hinged to the latter, we combine with the wick tube au
intermediate air tube, the bottom of which, when the burner is in position for use,
rests upon the upper end of the air tube passing through the oil tank, a layer of
cork or other suitable material being used between such parts to form a sufficiently
tight joint, and in order to prevent "weeping" of any condensed vapor over the
upper edge of the lower air tube or part of air tube to the exterior of the tank,
we form the co-fitting parts inclined towards the interior of the tank or we apply
a slightly rising lip all round the inner edge of the top of such air tube, so that
any condensed vapor accumulating on such part shall run back into the tank. The
wick tubes and pinion chambers are at their bottom made to fit a suitable fitting
around the lower air tube.
In cases where the burner is not hinged to the tank, the air tube passing through
the tank has its upper end terminating above the tank top, and the wick tubes,
each with its connected pinion case, are passed into openings in the tank top on the
outer sides of the air tube and fit suitable fittings formed in the tank top at such
parts, the support for the cone and the perforated diaphragm being slipped in position
over the wick tubes and retaining the parts in their correct positions.
If desired the air tube passing through the tank can be dispensed with, in which
case the wick tubes and intermediate air tube may be provided at their bottom
with a fitting to fit a corresponding fitting in the tank top, in which case a
perforated chamber is fixed around the wick tubes and supplies air to the
intermediate air tube through end openings in the latter.
As a modification the perforated chamber surrounding the wick tubes and air
chamber may be fixed to the tank top and formed to receive the fitting at the
lower end of the wick tubes and air chamber and provided with end openings
to fit against and conduct air to the aforesaid end openings in the air tube.
A perforated diaphragm is in either case fitted into the air tube to diffuse the
air equally therein.

We, ELIZA THORPE, formerly 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, 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 class of lamp or lamp stove in which two or more
flat wicks are mounted parallel to each other and a central or intermediate air
supply is provided between the wicks, and the invention consists of a novel mode of
construction of such class of lamps and lamp stoves.
The invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is a sectional elevation of a lamp stove with the parts in position for use
and Fig. 2 is a sectional elevation of the same lamp stove showing the chimney
and burner turned on their hinge joint and separated from each other and from
the tank.
a is the tank, which is provided with feet a' to raise the bottom above its support
and thereby form an air space beneath the same; 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 air to the inner surfaces of
the flames.
The burner has two wick tubes, wick-raising pinions c c, a perforated
diaphragm or basket d, a seat e for the cone and chimney 1, and a flat fitting g to
fit a corresponding socket formed in the burner fitting a³ on the tank top. To the
burner, between the wick tubes bb, is fixed an air tube i to form a continuation of
the tube up to a short distance below the tops of the wick tubes bb. The parts
above described, separately considered, form no part of our present invention.
According to our present invention, instead of forming the air tubes a² and i of
such lengths and proportions as to fit the one within the other, we now make the
lower end of the tube i to fit on the upper end of the tube a, a layer of cork or
other suitable material being interposed between such parts to secure a tight
joint, and, in order at the same time to prevent as far as possible the "weeping
of any condensed vapor over the upper edge of the tube af to the exterior of the
tank, we form the co-fitting parts of such air tubes inclined towards the interior of
the tank as shown, or we apply a slightly rising lip all round the inner edge of the
top of the air tube a², so that any condensed vapor accumulating on such part
shall run back into the tank. So far as above described the burner inay be capable
of complete removal from the tank and of being placed in position vertically and
of being secured in position for use by any of the well known catches or fastening
means. We, however, according to our present invention, connect the chimney
seat e and burner rigidly together and hinge the chimney scat e as heretofore to
the pink so that the seat e and burner can be moved into and out of position for
use by simply turning them on the pin k, a spring catch m being employed as
heretofore to secure the seat e and chimney in position for use and to facilitate
access to the burner.
It will be readily understood that the present invention, although described in
connection with a lamp stove, is equally applicable to lamps.
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 stoves and lamps such as those described and claimed in Specification
No 23 102 of 1891 the arrancament and combination of the hinge the which the

page_text: wick holders and the whole top of the stove or lamp may be turned over) and of
the divided air tube ai fitting together by means of a cork or other suitable
joint, the air tube a² being bevelled upon its upper edge towards the interior of
the tank and the lower end of the air tube being made to fit the same, all
constructed and arranged for the purposes hereinbefore set forth and as illustrated
in Figs. 1 and 2.
2. In oil stoves and lamps such as those described and claimed in Specification
No. 23,102 of 1894, the arrangement and combination of an air tube a² passing
through the tank and bevelled upon its upper edge towards the interior of the tank
and an air tube i carried by the burner and formed at its lower end to fit the upper
end of the air tube a' and a layer of cork or other suitable material between such
parts, all constructed and arranged for the purposes hereinbefore set forth and as
illustrated in Figs. 1 and 2.
