PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating and Cooking by Means of
Mineral Oil Lamps.
I, JOHN HENRY BROWN, of 16 Queens Road, South Norwood, in the County
of Surrey, England, Clerk, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a simple apparatus whereby an ordinary
mineral oil lamp may be used for heating rooms, and also for cooking purposes, at
the same time, the apparatus is so constructed that it can be used as a drawing
room or reading lamp staud.
It consists of securing to a suitable base plate three or more hollow columns in
each of which is arranged a telescoping rod; these rods are attached to, and support
a gallery, which may be either raised or lowered to suite the varying heights of,
the lamps at present in use and can be adjusted and firmly held in the desired
position by suitable binding screws situated at the upper portion of the columns.
Said gallery is formed by an upper and lower annular plate, constructed in such a
manner that the rim of the upper plate is shaped to meet and be secured to the
rim of the lower one. Each plate has a central opening or aperture to allow the
heat from the lamp to impinge upon or come in direct contact with the bottom of
the cooking utensil. A recess is made in said upper plate to prevent the contents
of the utensil should it, say, boil over or spill from running down the side of the
gallery, in which case it is directed on to the lower plate, and subsequently
evaporated by the heat from the lamp; a small flange, around the aperture in the
lower plate prevents it from coming in contact with the chimney.
When the apparatus is required for heating rooms a small disc baving a dished
lining is placed over the aperture in the upper plate, so as to form a chamber
between the two plates, to receive the products of combustion which are finally
emitted through small perforations formed around the gallery in order that the
heat may be evenly distributed.

Improvements in Apparatus for Heating and Cooking by Means of
Mineral Oil Lamps.
1, JOHN HENRY BROWN, of 16 Queens Road, South Norwood, in the County of
London, England, Clerk, 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 object of my invention is to provide a simple apparatus whereby an ordinary
mineral oil lamp may be used for heating rooms and also for cooking purposes, at

page_text: the same time, the apparatus is so constructed that it can be used as a drawing
room or reading lamp stand.
But in order that the invention may be clearly understood reference is made
to the accompanying sheet of drawings in which (A) represents a suitable base
plate provided with handles similar to (B). Two hollow columns (C) and (C) are
rigidly secured to said plate in each of which, is arranged a telescoping rod (D)
upon the upper ends of these rods are fixed the brackets (E) and (E) which
are attached to and support a gallery hereinafter explained. By the use of these
rods the gallery may be either raised or lowered to suit the varying height of the
lamps at present in use, and firinly held in the desired position by the clips (F)
and (F) which are forced into the notches (G) by the spring (H) arranged upon
both the binding screws (I) and (J) said binding screws however may be used
without the clips if desired.
The beforementioned gallery is formed by an upper and lower annular plate,
constructed in such a manner that the rim portion of the upper plate (J) is turned
downwardly to meet and be secured to the rim of the lower plate (K). Each plate
has a central opening or aperture to allow the heat from the lamp to come in
contact with the bottom of the utensil when the apparatus is used for such
purposes. A funnel shaped contrivance (L) having three projecting arms similar
to (M) is arranged centrally between the upper and lower plates, and is for the
purpose of increasing the rigidity of said plates and also assisting to draw
unvitiated air into the heating chamber formed between the plates. A ridge (N)
is made around the upper plate (J) to prevent the contents of the utensil, should
it, say, boil over or spill, from running down the side of the gallery, in which
case, it is directed on to the lower plate (K) and subsequently evaporated by the
beat from the lamp; a small flange (O) formed around the aperture in the lower
plate prevents it from coming in contact with the chimney.
When the apparatus is required for heating. rooms a small hinged disc (P)
having a suitable lining is placed over the aperture in the upper plate, the effect
is that the products of combustion together with the air which is drawn in through
the contrivance (L) enter the aforesaid chamber and are finally emitted through
the perforations (Q) formed around the gallery.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
clair is:
Firstly. An apparatus for heating and cooking by means of a mineral oil lamp,
consisting of a suitably supported gallery formed by the upper and lower annular
plates (J) and (K) each having a central aperture; the upper plate (J) being
also provided with the hinged disc (P) whilst around the lower plate (K) are
the perforations (Q), substantially as herein set forth and as illustrated.
Secondly. In an apparatus such as herein described the annular plates (J)
and (K) forming a chamber in combination with the funnel shaped contrivance (L).
Thirdly. In an apparatus such as herein described the combination with the gallery
of the adjustable supports consisting of the hollow columus (C) and (C) and the
rods (D) and (D).
