page_text: 1, JOHN HENRY BROWN, of 16, Venner Road, Sydenham, in the County of
Surrey, Clerk, do hereby declare the nature of this invention to be as follows:-
This invention relates to an apparatus with which a mineral oil lamp is used
for cooking purposes.
In carrying out my invention I secure to an annular cast iron base, two
supports; one of which is placed opposite to the other. To these supports are
attached adjustable bars which are secured to and support an annular gallery
which may be either raised or lowered to suit the varying heights of lamps at
present in use; the supports and the bars being clamped in the desired position
by a bolt and nut, situated at the upper end of each support. The bars have
each a longitudinal slot therein so that they can be adjusted vertically without
removing the bolts. The supports have also perforations therein and into one
of these on each side enters a small stud on the lower end of each bar before.
being tightened by the bolt so as to ensure perfect rigidity of the gallery.
The gallery is formed by an upper annular frame and a lower plate having a
central opening therein around which the edge is turned up.
Lugs are projected from the upper frame towards the centre of same, to carry
any suitable cooking utensil; the turned up edge around the opening in the
lower plate prevents the contents of the utensil should it boil over or spill from
running on to the lamp.
Over the opening in the upper frame is fitted a hinged hollow cover made in
such a manner as to form a chamber. By the use of this chamber the direct heat
from the lamp is prevented from passing through the cover and is diverted
hrough the space between the upper frame and lower plate of the gallery; the
over being of course closed when the stove is used for heating purposes.
The lamp which may be of any suitable construction is placed in an adjustablo
tand arranged on the base beforementioned; the distance between the chimney
nd the gallery being adjusted in the manner herein stated.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to an apparatus with which a mineral oil lamp is used
for heating and cooking purposes.
In order that my invention may be clearly understood I will describe the same
with reference to the accompanying drawings in which.-
Figures 1 and 2 are sectional elevations of my improved lamp stove; in
Figure 1. the gallery is also shewn by dotted lines in a raised position and in
Figure 2 the hinged cover-plate of the gallery is shewn raised as is required
when the stove is employed for cooking purposes.
Figure 3 is a cross section through X-X of Figure 2 and
Figure 4 is a perspective view of the adjustable lamp holder.
In carrying out my invention I secure to an annular cast-iron base (A) furnished
with, preferably, four feet such as (B), two upright supports (C) and (C) which
are arranged one opposite to the other; each support having suitable ornamental
side pieces formed thereon for keeping the same rigid. In contact with these
supports are adjustable bars (D) and (D) which are secured to and carry an
annular gallery (E) which can, thereby, be either raised or lowered to suit the
varying heights of lamps at present in use; the said supports and the bars being
clamped together in the desired position by means of the wing-nut bolts (F)
and (F) at the upper ends of the supports. The bars (D) and (D) have each a
longitudinal slot (G) therein which enables the same to be adjusted vertically
without removing the clamping bolts. Said bars are situated in grooves in the
supports as shewn in Figure 3 so as to prevent them from swinging over sideways.
The supports have also each a vertical row of perforations (H) therein and into
one of these perforations on each side enters a small stud or projection on the
lower end of each bar,, before the bolts are tightened up, so as to ensure perfect
rigidity of the gallery.
The gallery (E) is formed by an upper annular cast-iron frame (I) and a lower
plate (J) having a central opening (K) therein, around which the edge is turned
up. Lugs (L) are projected from the upper frame towards the centre of same
so as to carry any suitable cooking utensil when required. The turned-up edge
around the opening in the lower plate prevents the contents of the utensil should
it boil over or spill from running on to the lamp.
Over the opening in the upper frame of the gallery is fitted a hinged hollow
cover plate (M) made with a flat top and convex bottom so as to form a
chamber (N) by the use of which the direct heat from the lamp is prevented
from passing through the cover plate, and is diverted through the space between
the upper frame (I) and the lower plate (J) of the gallery and finally through
the annular outlet (0); the cover plate (M) being of course closed when the
stove is used for heating purposes.
The lamp employed with the apparatus may be of any suitable construction,
but I prefer to use a central-draught lamp or one with a duplex burner.
The lamp is placed in the holder (P) which rests on the lugs (Q) projected
from the base (A). Said holder is so formed that it can be adjusted in circum-
ference to suit the varying sizes of lamp reservoirs. This is effected by placing
the bolt (R) through the one suitable, of the several perforations formed in the
holder, and then screwing on the nut.
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 :-
Firstly: An apparatus with which a mineral oil lamp is used for heating and
cooking purposes, constructed in the manner substantially as herein set forth and
as illustrated.
Secondly-In an apparatus such as described, the hinged hollow or chambered

page_text: cover-plate (M) of the gallery (E) constructed in the manner and for the purposes
substantially as herein set forth.
Thirdly: "In combination with an apparatus such as described, the adjustable
lamp-holder (P) substantially as herein set forth.
