COMPLETE SPECIFICATION.
Improvements in Gas-stoves or Heaters.
I, CHARLES STANFORD UPTON, of 42 Park Place, in the City of New York,
County and State of New York, U.S.A., Manufacturer, do hereby declare the
nature of my invention for IMPROVEMENTS IN GAS-STOVES OR HEATERS, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The object of my invention is to provide a gas-stove or heater, which shall be
simple of form, cheap of construction, and efficient in action, and to that end my inven-
tion consists of the construction, combination, and arrangement of the various parts
of my improved gas-stove or heater, shown and described in the following
Specification, of which the accompanying drawing forms a part, wherein similar
letters and numerals of reference designate like or equivalent parts wherever found
throughout the several views, and in which :-
Figure 1, is a view of my improved gas-stove or heater partly in central vertical
section thereof;
Figure 2, is an exterior side view thereof; and
Figure 3, is a top plan view of the lower portion or base of such stove or heater,
showing the burner in position thereon, the heating drum being removed.
Referring to the drawing
The reference letter A designates a supporting base of suitable form, B the
heating drum supported by said base, and C the burner located upon the base A
and within the drum B.
The base A is formed of cast iron or other suitable metal or material, and is
preferably of substantially the circular form shown, being provided on its upper
side with an annular groove 1, and having at the bottom three or more short legs 2,
by which the entire device is supported in an elevated position so as to allow a free
circulation of air beneath the same.
Located in the center of the base A, and preferably raised slightly above the
level of the annular groove 1 is a ring 3 connected with the annular portion of the
base A by three or more spokes or braces 4, said ring or spokes being preferably
cast or otherwise formed integral with the rest of said base A.
The burner C, consists of a central hollow hub 5, closed at one end, and open at
the other as shown at 6 in Fig. 1, into which hub are screwed or otherwise securely
fastened radial pipes 7, in communication with the hollow of the central hub 5 at
their inner ends and closed at their outer, and provided on the upper sides with
burner-holes 8 for the escape and ignition of the gas fed to the burner C. The
construction of the burner is such that it will throw a perfect yellow flame and no
other.
The lower or open end 6, of the hub 5, is provided with an exterior screw-thread
adapted to screw into a suitably interiorly screw-threaded elbow 9, into the other
end of which is screwed a short pipe 10 which passes through a hole formed for that
purpose in the base A, on the outer end of which pipe is a suitable stop-cock and
connection 11, adapted to be brought into communication with a suitable gas-supply-
pipe in any well known manner. Formed in the upper closed end of the hollow
hub 5, is an interiorly screw-threaded hole 12 into which is screwed, when the parts
are all in position, a threaded rod 13 having a slotted head 14, or other suitable
means for turning the same, at its upper end, by which such rod is screwed firmly
n place.
The drum B, the lower edge of which rests in the annular groove 1 of the base A,
is formed preferably of sheet-iron, and is provided at the top and bottom with a

page_text: series of perforations 15 to allow air to enter and escape from the same, and is also
preferably provided with annular corrugations 16 which allow of the expansion and
contraction of said drum without interfering with the stability of the store. This
drum B, is closed at the top by a top-plate 17, which is of slightly larger diameter
than the drum, and is preferably provided with a downwardly turned flange 18
around the outer edge thereof, and with a central hole having a downwardly turned
flange 19 surrounding the same by which said hole is made larger at the upper end
than at the lower end thereof, so as to receive the head of the rod 13 and allow the
top thereof to lie flush with the top surface of the top-plate 17, as shown in
Fig. 1.
The top-plate 17 is also preferably provided with an annular groove 20 in which
ordinarily rests the lower end of a removable ornamental cap 21 preferably formed
of spun metal and having a handle 22 by which the same may be easily removed,
that portion of the top-plate 17 lying within the annular groove 20 being preferably
perforated, as shown, to allow the heated air to come in contact with any cooking
utensil placed on said top-plate, when the cap 21 is removed and the stove is used
for cooking.
Located within the drum B, above the spokes or braces 4, but below the
burner C, is a perforated plate or air distributor 23 which prevents draughts of air
from disturbing and rendering unsteady the flames of the burner, which burner is
ignited by the insertion of a match or other suitable lighting device through any of
the lower holes or perforations 15 of the drum B, or if desired said drum may be
provided with a suitable hinged door (not shown) for that purpose which may be
of any suitable form of construction.
The various parts of the stove being apart and it being desired to assemble them
together in proper position for use, the perforated air-distributing plate 23 is placed
in position on the base A, and the radial pipes 7 having been screwed into the
hollow hub 5 of the burner C, the lower end of said hub 5 is passed through the
ring 3 of the base A, and screwed firmly into the elbow 9 until the said ring 3 is
tightly held between the end of the elbow and the flange of said hub 5, as shown in
Fig. 1, and as soon as these parts are securely fastened together, the pipe 10, to the
outer end of which has already been secured the stop-cock and connection 11, is
passed through the hole provided therefor in the side of the base A, and securely
screwed into the open end of the elbow 9. The drum B is then placed in position
with the lower edge thereof resting in the annular groove 1 of the base A, the top-
plate 17 is placed thereon, and the screw-threaded rod 13 being passed down
through the central hole of said top-plate and screwed down into the hole 12 formed
in the top of the hub 5 of the burner C, until the rod 13 forcing down the
top-plate 17 will hold the top-plate, the drum B, and base A, firmly together,
when the parts will all be in position, and the stove ready for use.
If desired the burner C, may be cast or otherwise formed of one single piece
of metal, and many other changes and modifications in the construction, com-
bination and arrangement of the various parts of my improved gas-stove or
heater, may be made without departing from the scope of my invention, and I do
not intend to limit myself to the exact form of construction shown, but;
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:
1. In a gas-stove or heater, the combination with a suitable base, of a burner
secured thereto, and a drum supported by the base, and secured to the burner,
substantially as shown and described.
2. In a gas-stove or heater, the combination with a suitable supporting base,
of a burner secured thereto, a drum having a top provided with a central hole
Gupported by the base, and a screw-threaded rod passing through the hole in the
top of the burner and screwing into a threaded hole in the burner, substantially
as shown and described.

page_text: 3. In a gas-stove or heater, the combination with an annular base of a drum
supported thereon, a top having a central hole supported by the drum, a burner
consisting of a series of radial pipes communicating with a hollow hub at the
center, which hub is provided at the top with an interiorly screw-threaded hole, and
a screw-rod adapted to pass through the central hole of the drum-top and screw
into the central hole of the burner in such manner as to hold the base, drum and
top firmly in place, substantially as shown and described.
Dated this 9th day of January 1894.
