COMPLETE SPECIFICATION.
Improvements in Reversible Hydrocarbon Generators and Burners.
1, BENJAMIN GREEN DEVOE, of 751 South Elizabeth Street, Lima, Allen
County, Ohio, United States of America, Machinist, 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 and efficient reversible bydro-
carbon generator and burner, and it consists in the novel features of construction
hereinafter described and particularly pointed out in the clainis.
In the accompanying drawings forming part of this Specification wherein like
letters of reference indicate like parts-
Figure 1, is a top or plain view of my improved reversible hydrocarbon
generator and burner, with the deflector partly broken away to show the
burner.
Figure 2, is a side view thereof; one of the burners being removed, and
Figure 3, is a similar view partly in section, and showing the tubular vaporizer
and burners in their reversed positions.
In the drawings A designates the base having a deep forward or pan portion B,
and surrounded by a flange C. D is a frame corresponding in outline substantially
to the base A, and supported above the same upon standards E secured thereto.
At the opposite ends of the frame D are located upright supports F upon which
a deflector G is movably supported.
Upon the base A, and within the frame are arranged two sets of standards H
and H which are made integral with the base A, and recessed upon their inner
sides at the top, to receive in each case the burners 1. The said burners consisting
of an outer superheating drum J closed at one end and provided with apertures a
and open at its other end. Within this superheating drum J is a centrally disposed
shell K, open at both ends, and secured at its top to the outer superheating drum J,
thereby forming an annular space between the drum J and shell K into which the
air is drawn and superheated. The vapor from the vaporizer Q is forced into the
central shell K, above which it is mixed with the surrounding superheated air
issuing through the apertures a in about the proportion of 80 parts of air to
20 parts of vapor, which mixture will, upon being ignited, burn without odour or
smoke, and produce a flame of intense heat.
Upon the surface of the base A are seats L cast integral therewith, and at
specified places upon the frame D are situated similar seats M, and lugs N, N'
along the edges thereof. O is the oil supply pipe provided with a veedle valve P,
and is the tubular vaporizer supported upon the frame D, and secured thereto
by hook bolts b, and nuts e; said vaporizer Q terminating in a pipe portion Q
which dips downwardly and extends across the base A to which it is secured by
similar hook bolts b, and nuts <.
In the upper side of the pipe portion Q', directly beneath the center of each of
the burners is a very small vapor outlet through which the vapors, after passing
from the vaporizer Q, is forced into the central shell portion K of the burners.
To start the apparatus it becomes necessary to place a quantity of asbestos in
the deep forward or pan portion B of the base A, and then by opening the valve P
of the oil supply pipe permit a small quantity of oil to enter the vaporizer, and
after passing into the pipe portion Qissue therefrom through the outlets d, this
will then saturate the asbestos, and after igniting the same the heat produced

page_text: thereby will in a very short while vaporize the oil admitted to the vaporizer Q.
The vapor thus generated will, after passing from the vaporizer Q enter the pipe
portion Q, and be driven with great force through the outlets d therein into the
central shell portion K of the burners above which the combustion will be rendered
more perfect by the admixture of the large quantity of superheated air issuing
from the apertures a in the top of the superheating drum J.
By constructing the vaporizer Q tubular in form, and supporting it at a few
places only upon the frame D, the heat will be enabled to circulate freely around
and envelop the same, and as a small quantity of oil will be distributed over so
large an area in direct presence of the heat the same will be almost immediately
vaporized.
By means of the movable deflector G which is supported above the burners, the
flames and heat produced thereby may be directed to any desired part of the stove,
and where desirable the deflector may be entirely removed by means of an ordinary
stove-lid lifter, said deflector having suitable recesses e therein, into which the lifter
may be inserted.
It will be observed that the burners I, the vaporizer Q and pipe Q connected
thereto, are not rigidly secured to their respective supports, the object of which is
to permit of their being readily removed and reversed as is shown in Figure 3.
The operation in the reversed position being the same as in the first, except that
the vapor will be forced downwardly from the pipe portion Q now located above
the burners I, the combustion takes place beneath the burners instead of above
them, and the heat and flames be deflected by the base A. instead of the movable
deflector G.
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. A hydrocarbon generator and burner comprising a supporting base, a frame
corresponding in outline substantially to said base, and supported upon suitable
standards secured thereto, a deflector movably supported above said frame, a
reversible vaporizer having a pipe provided with vapor outlets, and an oil supply
pipe communicating therewith, and burners reversibly disposed in proximity to the
vaporizer, and vapor outlets in the pipe communicating therewith, substantially as
specified.
2. A hydrocarbon generator and burner, comprising a supporting base, a frame
corresponding in outline substantially to said base, and supported upon standards
secured thereto, a deflector movably supported above said frame, a reversible
tubular vaporizer supported upon said frame, having a pipe provided with vapor
outlets, and an oil supply pipe communicating therewith, and burners reversibly
supported in proximity to said vaporizer, and the vapor outlets in the pipe
communicating therewith, substantially as specified.
3. A hydrocarbon generator and burner comprising a supporting base having a
deep forward or pan portion, a frame corresponding in outline substantially to said
base, and supported upon standards secured thereto, said frame having upright
supports at its opposite ends, a deflector morably supported thereon, a reversible
tubular vaporizer extending around and secured to said frame, an oil supply pipe
provided with a suitable valve, and a pipe provided with vapor outlets communi-
cating with said vaporizer, and burners reversibly supported upon standards
secured to the base, whereby the vapor will be mixed with superheated oxygen in
about the proportions specified, substantially as herein shown and described.
4. A hydrocarbon generator and burner comprising a supporting base A having
a deep forward or pan portion B, and surrounded by a flange C, a frame Ď
supported above said base upon standards E secured thereto, a deflector G,
uprights F secured to the opposite ends of the frame D. for supporting the said
deflector, a reversible tubular vaporizer Q supported upon seats L on the frame D
and secured thereto by hook-holts and nuts e, an oil supply pipe O having a

page_text: needle valve P, and a pipe Q' provided with vapor outlets d connected to, and
communicating with said vaporizer, and reversible burners I having standards H, H¹
for supporting the same in proximity to the reversible tubular vaporizer Q, and
vapor outlets in the pipe Q communicating with said vaporizer, substantially as
herein shown and described.
5. A reversible hydrocarbon burner comprising an outer superheating drum
having vertical sides, an open end and a closed end provided with a series of
apertures, and a cylindrical central shell portion open at both ends, and secured
within said superheating drum to the top thereof, substantially as specified.
