page_text: 4 is a deban perspec
Fig. 5 is a perspective detail of the valve at the bottom of the mixing-chamber,
partly broken away to show the construction of parts operating in connection
therewith.
Referring to the said drawings, the letter A designates a bowl for the reception
of petroleum or gasoline, or both, and the said bowl has the usual handle H and a
plug G, through which it may be fed.
Screwed into said bowl by means of the threads B is a tube C, provided, where
shown, with about four oval holes D and the upper end of this tube is continued in
a reduced extension R and provided near its upper end with about eight holes S.
The letter L designates a pair of pins projecting from opposite sides of the
tube C below said oval holes D and F is a regulating-ring surrounding said tube,
having two inclined slots M embracing said pins, and provided with an operating
handle 1. By this means when the handle is moved from side to side, the slots
in the regulator, engaging the pins L, will cause said regulator to move spirally
up and down upon the tube C and the holes D will be thereby more or less opened
at their upper ends, as will be obvious.
Z is a wick, whose lower end extends to the bottom of the bowl A. and whose
body passes up within the tube C to a point about opposite said holes, and this
wick is raised and lowered by any suitable means, not here shown and forming no
part of the present invention.
A small pipe E is preferably arranged within the tube C, being connected to one
side thereof at the point e, and this tube extends from a point within the bowl A
above the liquid therein to a point within the tube C above the holes D. The object
of this pipe is to conduct into the tube any vapor which may be formed within the
bowl by reason of the heat communicated thereto from the flame. Surrounding
the tube C above the regulator F is a sleeve provided with inclined slots
embracing pins N on the sides of said tube in substantially the same manner as did
the slots M in the regulator above described.
J is a pipe surrounding the sleeve l, than which it is considerably larger_and
longer, its lower end extending downwardly to a point opposite the lower ends of
the holes D and the pipe J is connected to the sleeve by bars a, as seen in Fig. 2,
the whole being turned upon the tube C by a handle K similar to that upon the
regulator. This device is what I call the "fender" because when it is lowered
the lower end of the larger pipe J stands opposite the holes D, inside of which the
flame is located and the latter is therefore prevented from being extinguished by

page_text: sudden drafts of air; but the fender may be raised, when desired, so as to gain
access to or permit inspection of the regulator and the parts within it.
The letter W designates a mixing-chamber, which is detachably secured by
threads V to its bottom and the latter is provided with a number of holes and is
centrally rigidly mounted upon the extension R. Within this chamber is located
a disk T, which turns around the extension R and rests upon the bottom of the
chamber, being operated by a handle Q projecting downwardly through a slot in
said bottom and said disk is provided with holes t, adapted to register with the
holes in the bottom, or when the disk is turned by the handle to be thrown
partially or wholly out of register therewith, whereby the disk constitutes a
regulating-valve governing the admission of air through the bottom of the mixing-
chamber to join the vapor that issues from the holes S. Said mixing-chamber has
an upwardly-extending tube X upon which is tightly but removably fitted a
burner of any approved construction, and the upper end of this burner is
enlarged so as to present a large heating-surface or so as to support a dish or
cooking vessel the upper end of the burner being covered by a fine sieve,
whereby soot and other particles are prevented from dropping into the device.
Upon the extension R just below the mixing-chamber W is tightly fitted a
sleeve d, and extending outwardly and radially from the upper end of this sleeve is
a plate P which is bent inwardly and again connected with the sleeve d at its
lower end, the whole forming another fender below the holes in the bottom of
the mixing-chamber W, which fender may be adjusted vertically upon the
extension R and will prevent a sudden inflow of air through the said openings or
holes into the mixing-chamber. To said extension R inside the hole through
the center of the valve T are secured two tongues U whose upper ends are bent
outwardly from said extension and beneath which the valve T turns as it is
operated by the handle Q.
This improved vapor-stove being constructed as above described, the operation
thereof will be as follows: A light is applied through one of the holes D to the
inflammable liquid, which is drawn upwardly by capillary attraction through the
wick Z and the regulator F is turned so that the proper amount of air will be
admitted through the holes D to mix with the burning liquid and create vapor.
The regulator-fender J is turned as above described, so as to prevent the sudden
admission of an excessive quantity of air which would interfere with the formation
of this vapor. The vapor rising through the extension R issues from the holes S
(the upper end of the extension being closed) and air admitted through the holes
in the bottom of the mixing-chamber W, its admission being regulated by the
valve T, as above explained, mixes with the vapor in this chamber. The upper
fender P prevents a sudden draft of air rushing into the mixing-chamber which
would cause the mixing to be imperfect and the burning to be irregular.
The mixed vapor and air passes upwardly through the tube X into the burner Y,
and where it issues from the sieve it will burn with a non-luminous flame,
possessing great heating power.
If a dish or vessel be placed upon the burner Y the contents thereof will be
quickly and highly heated or if the entire device be placed within a surrounding
drum or suitably arranged in any other manner, the heat from the flame may be
used for heating purposes, all as is well known in the art and forms no part of the
present invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is
1. In a vapor-burner, the combination with the bowl A, the tube C rising therefrom
and having a number of holes D, a mixing-chamber and a burner carried by the
upper end of said tube, and a regulator surrounding said holes, of a sleeve fitting
said tube above the holes therein and having inclined slots O, pins N on said tube,
with which said slots engage, a pipe J surrounding said sleeve and extending below

page_text: the lower end thereof, bars a, connecting said sleeve and pipe, and an operating-
handle K extending outwardly from said pipe, as and for the purpose set forth.
2. In a vapor-burner, the combination with the bowl A, a tube C rising there-
from and having a number of holes D, a mixing-chamber and a burner carried by
the upper end of said tube, and means, substantially as described, for regulating
the admission of air through said holes, of a small pipe E secured within and to
one side of the tube C and extending from a point within the bowl above the
liquid therein to a point within the tube above the holes therein, as and for the
purpose set forth.
3. In a vapor-burner, the combination with the bowl A, the tube C rising

bottom and around said extension, and having holes t, adapted to register with said
holes in the bottom, an operating-handle Q connected to said disk, and a burner Y
at the upper end of said chamber, all substantially as described.

controlling the admission of air through said holes, a sleeve d, tightly fitting upon
said extension, a fender-plate l' extending outwardly from said sleeve for the
purpose set forth, and a burner Y at the upper end of said mixing-chamber, all
substantially as described.
5. In a vapor-burner, the combination with the bowl A, the tube C rising
