Improvements relating to Oil-lamps and Lamp-stoves and to
Burners therefor.
I, JAMES PRICE of 148, Beckenham Road, Penge, in the County of Surrey,
Grocer and Oilman, 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:-
My invention relates to oil-lamps and lamp-stoves of the kind or class adapted
for burning paraffin and other fluid hydrocarbons without the use of a lamp-glass or
chimney, and is chiefly designed to provide for producing a more perfect combustion
of the illuminant and a brighter and steadier flame, whilst keeping the base of the
burner and the oil-reservoir cooler than is practicable in lamps or lamp-stoves of
this kind or class as heretofore constructed.
One feature of my said invention is the combination, with the burner of an
oil-lamp or lamp-stove, of a closed or unperforated gallery or globe-socket so
arranged that air cannot enter the globe of the lamp, or the casing around the
burner of the lamp-stove, through the space between the outer lamp-cone and the
lower edge of the said globe or casing, and therefore all the air supplied to
the flame must pass through the lamp-cone or lamp-cones.
In this manner I ensure the production of a strong draught through the lamp-
cone or lamp-cones and thus produce a more perfect' combustion of the oil and
increase the brightness of the light, whilst carrying away the heat from the base of
the burner and from the upper surfaces of the oil-reservoir in such a manner as to
keep the same cool.
I find it advantageous, in applying my invention to an oil-lamp, to employ, in
combination with a lamp-burner having a closed or unperforated gallery or
globe-socket as above mentioned, a globe or shade having the top thereof closed,
and having suitable perforations around the upper portion thereof for the escape of
the products of combustion.
In applying my invention to a lamp-stove, I combine, with the closed or
unperforated gallery, a circular or oval casing having suitable apertures at or near
the top thereof for the escape of the products of combustion.
In the accompanying drawing, I have shown how my said invention may be
conveniently and advantageously applied to a lamp-burner having two lamp-cones
arranged as described in the Specification of former Letters Patent dated
4th February 1893, No. 2539.
a is the oil-reservoir; is the base of the burner; c is the inner lamp-cone and d
the outer lamp-cone.
e is my closed or unperforated gallery or globe-socket, which is fitted upon the
lower portion of the outer lamp-cone d, and upon which is supported a globe or
shade g which is closed at the top but has perforations g¹ around the upper part
thereof for the escape of the products of combustion. The said gallery is made
in the form of an annular plate having inner and outer upwardly turned flanges e¹, e³.
The inner flange e fits tightly upon the outer cone d, whilst the outer Hange e
forms a socket to receive the lower edge of the globe g.
It is evident that, as the air in the globe becomes heated and escapes through the
apertures g', cold air will enter the said globe through the two lamp-cones, but
cannot enter between the outer lamp-cone and the lower edge of the globe. By
thus controlling the admission of the air for supporting combustion so as to cause it
to pass through the lamp-cones only, a very strong draught is produced, which
ensures more perfect combustion of the illuminant, and, by reason of the access of a

page_text: large quantity of cold air to the base of the burner and the upper part of the
oil-reservoir, aids in keeping these parts cool.
I do not confine myself to the special construction or arrangement of the parts
above described, as such construction and arrangement can be modified to suit
different kinds of burners. Moreover the flange instead of forming a socket for
the globe may, if desired, extend upward within the said globe, so as to keep the
same concentric with the burner.
The gallery e is preferably provided with one or more clips or catches for
retaining the globe in position thereon, and the operating levers of these catches are,
in some instances, passed through slots in the gallery e, but these slots are not
intended for the admission of air and are formed in such a manner as to prevent as
far as possible the passage of air through them into the said globe.
I can,
if desired, use a globe having an open top; I find it more advantageous,
however, to use a globe such as is shown in the drawing.
When I apply my improvements to a lamp-stove I substitute for the globe ga
suitable casing, preferably of metal, which is supported upon the gallery e or, if
desired, may be formed with or attached to the said gallery. This casing may be
open at the top and have holes or notches formed in or near its upper edge for the
escape of the products of combustion. The said casing is preferably so constructed
and arranged that a cooking vessel may be supported thereon.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. The combination, with the burner of an oil-lamp or lamp-stove, of a
gallery or globe-support secured upon the lamp-cone and constructed without any
holes or openings for the admission of air to the space above the same and around
the said lamp-cone, for the purpose above specified.
Second. The combination, with the burner of an oil-lamp or lamp-stove having
two lamp-cones, of a closed or unperforated annular gallery or globe-support
secured upon the lower part of the outer lamp-cone, substantially as, and for the
purpose, above specified.
Third. A lamp having two lamp-cones and provided with a closed or unperforated
annular gallery or globe-support secured upon the outer lamp-cone, and with a
globe having its top closed and having openings around its upper part, as above
described with reference to the accompanying drawing and for the purposes
specified.
Fourth. A lamp-stove having two lamp-cones and provided with a closed or
unperforated gallery and with a casing supported thereon and having apertures at
or near the top for the escape of the products of combustion, substantially as
described.
