COMPLETE SPECIFICATION.
Improvements in Oil-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 OIL-STOVES OR HEATERS, 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 central draft oil-stove or heater,
which shall be light in weight, extremely simple and cheap of construction, and
highly efficient in action; and to that end my invention consists of the construction,
combination and arrangement of the various parts thereof, shown and described in
the following Specification, of which the accompanying drawing forms a part,
wherein similar numerals of reference designate like or equivalent parts wherever
found throughout the several views, and in which :-
Figure 1 is a front view of my improved oil-stove and heater, all save the oil-
font and supporting base thereof being shown in central vertical section;
Figure 2, is a front exterior view thereof;
Figure 3, is a view similar to Fig. 1 of a modified form of the construction shown
in said Fig. 1, and
Figure 4, is a top plan view of a modified form of the drum-supporting ring.
Referring to the drawings:-
The reference letter A designates a supporting base, B the oil-font supporte
thereby, C the burner supported by the oil-font B, and D the heating drum
supported by the burner. All these various parts are preferably of substantially
the form shown, and are formed preferably of suitable sheet metal in order to
secure lightness of construction. The base A is supported above the supporting
surface by legs 1, by which free access of air to the bottom of the central draft
tube 2 which extends entirely through the oil-font B, is allowed, the base A. being
for that purpose either bottomless, or provided with suitable perforations for the
air. The base is also preferably provided with handles a, by which the entire
device may be moved about as desired.
"
The burner C, is of the form well known as "The Rochester and is provided
with a wick-lift of that well-known type, and said burner is secured to the oil-
font B, in any desired manner preferably by a bayonet joint (not shown) of the
ordinary form. The inner tube 3, of said burner C, forms the outer wall of the
wick-chamber, the central draft tube 2, forming the inner wall thereof, while
the outer tube 4 of such burner, is provided with suitable perforations forming an
air distributor by which air is fed to the outside of the flame of the wick, passing
for that purpose through suitable passages 5 between the inner tube 3 and the
chimney holding gallery 6, surrounding the same; the air to feed the interior of
the circular flame passing up through the central draft-tube 2, and through per-
forations formed in a suitable air-distributing thimble or cone 7, supported by the
draft-tube 2, as shown.
Supported by and preferably secured to the burner C, is a drum supporting-
ring 8, preferably provided with an upwardly extending outer flange 9, within
which flange when in position rests the lower edge of the heating drum D, which
is held firmly in place by means of suitable set-screws 10 which are placed in
suitably threaded holes in the flange 9, as shown. This drum D, is preferably
provided with ornamental and strengthening corrugations 11, and with a top
plate 12, secured to the side walls of the same in any desired manner, which top
plate is provided preferably with an annular groove 13, adapted to receive the

page_text: bottom of a removable bell-shaped ornamental cap 14, provided with a handle 15,
said top-plate being provided with a series of perforations 16 within the annular
groove 13, by which the heated air from the interior of the drum D is allowed to
reach the bottom of any suitable cooking utensil placed thereon after removal of
the cap 14, when the stove is used for cooking; and to facilitate lighting the wick
of the burner C, said drum D, is preferably provided with a mica windowed door 17,
as shown. Said drum D, is provided with a series of perforations 18 in the side
wall thereof near the top, to allow of the escape of the heated air, when the stove
is used for heating.
Supported in the chimney supporting gallery 6, of the burner C, is a short
annular chimney 19 the upper edge of which curves upward outward and down-
ward, and which extends preferably to only about the height of the interior air
distributing thimble or cone 7, as shown in Fig. 1, said chimney being preferably
formed of spun metal, although if desired glass or any other suitable material
may be used for making the saine, and when such short chimney is used, it will be
found that a much longer and hotter flame is produced, and the combustion is more
perfect than when it is not so used.
In the modified form of construction of my improved oil-stove and heater,
shown in Fig. 3, instead of the short chimney 19, I use a long glass chimney 20 of
the ordinary form, and when such long chimney is used, I prefer to provide the
drum D, with a series of perforations 21 in the bottom portion of the side wall
thereof, similar to the upper perforations 18 therein, and if desired the drum
supporting ring 8 in either form of construction may also be provided with per-
forations 22, as shown in Fig. 4, and through these perforations 21 and 22, when
the stove is in operation, cold air will pass to the interior of the drum D to be
heated by being brought into contact with the chimney 20 and the drum D, and
then, mingled with the heated air from the chimney itself, will pass out through
the perforations 18, and also through the perforations 16, when the cap 14 is
removed.
It is evident that many changes in the construction, combination and arrange-
ment of the various parts of my improved oil-stove and heater may be made
without departing from the scope of my invention, and 1 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 inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a central draft oil-stove or heater, the combination with the burner, of a
short chimney 19 located within a heating drum perforated only near the top, the
sole ingress of air to the drum at the bottom being through the chimney, substan-
tially as shown and described.
2. In a central draft oil-stove or heater, the combination with the burner, of a
short chimney 19 supported by the burner, an imperforate drum-supporting ring 8,
surrounding the burner, and a heating drum perforated at or near the top thereof,
substantially as shown and described.
3. A short chimney for oil-stoves or heaters the top of which curves upward,
outward and downward, substantially as shown and described.
4. In a central draft oil-stove or heater, the combination with the burner, of a
glass chimney supported by the same, and a heating drum with perforations at the
bottom and the top, surrounding the chimney, substantially as and for the purpose
shown and described.
