Improvements in Hydrocarbon Gas Generators and Burners.
I WILLIAM HUMPHREY WHEATLEY, of the Firm of Wheatley and Mackenzie,
Engineers, and Patent Agents, of 40 Chancery Lane, in the County of London,
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 invention is an improved hydrocarbon burner, and is constructed with a
view of supplying the burner with a sufficient quantity of air without creating the
disagreeable roaring noise so common in hydrocarbon burners. This burner is also
constructed with a view of securing a complete vaporization of the oil and also of
mixing a definite quantity of air with said vapour at the point of combustion.
With these objects in view, my invention consists in the peculiar construction of
some of the parts, and also in the novel manner in which all the parts are combined,
as will be more fully hereinafter described and claimed.
In the drawings :
Fig. 1 is a front view of a complete burner.
Fig. 2 is a transverse section on lines X-X, Fig. 1.
Fig. 3 is a transverse section on line Y-Y, Fig. 1.
Fig. 4 is a horizontal section of the combined oil and vapour chamber...
Fig. 5 is a top plan view of the burner with the deflecting plate removed.
Fig. 6 is a detail sectional view.
In carrying out my invention I employ a frame 1, composed of a base 2, having
a sloping face, and a surrounding flange 3. Extending upwardly from this flange
on three sides of the base are the sides 4 composed of a series of vertical bars, and
all connected by means of a top rail 5. The opposite ends of this top rail 5 are
also connected by means of a front rail or cross bar 6, said bar forming with the
top rail 5, an open rectangular frame upon which are supported the oil, vaporizing,
and mixing chambers.
7 designates a combination chamber, provided with an integral arm 8 which rests
upon the bar or rail 6, while the rear end of the chamber is supported upon the top
rail 5, as shown in Figs. 2 and 5. This combination chamber comprises an oil com-
partment 9, a vaporizing compartment 12, and a vapour collecting compartment 13.
An oil supply pipe 10 enters one end of the oil compartment, and extends
nearly to the opposite end, which is closed by a screw plug 10'. The bottom of the
vaporizing portion is below the oil compartment, and is formed with an inclined
portion 11 down which the oil flows in a thin sheet, and is readily vaporized. The
vapour then ascends to the dome shaped collector 13, into which is led a delivery
pipe 15 said pipe 15 having hollow globular burners 16 at each end, and these
burners are each provided with the top and bottom apertures 17 and 20 respectively,
the upper apertures being bevelled at their inner and outer edges whereby the
vapour may issue therefrom with great force, and then expand rapidly, whereby a
more perfect combustion is attained. The burner pipe rests upon the central
bars 18 and the end bosses 19, and in the aperture 20, is screwed a plug 19¹ which
bears upon these end lugs as clearly shown in Fig. 6. These are for the purpose
of preventing the pipe warping, and to make it more secure, I employ the eye
bolts 21 and nuts 211, screwed thereon beneath the base.

page_text: 22 designates a mixer composed of an outer shell 23, and an inner shell 25, the
outer shell having integral arms 24 to support it upon the rails 5 and 6, and the
shell 25 is provided with lugs 25¹ to support it within the shell 24. The outer shell 23
is broader at the bottom, and the inner shell 25 is contracted at the bottom, so
that the space between the two shells is annular, and tapers toward the top. The
top of the inner shell is of such size that a coucentric opening is produced through
which air is drawn up between the shells, and inasmuch as the space between the
shells tapers, it will issue with great force. The contracted end of the inner shell
rests directly above the burner, so that the vapour passes straight up.
Said
vapour is given ample room to expand prior to the mixture with the air, which
entirely surrounds it, thereby making a complete admixture, and greatly aiding
combustion.
26 indicates a deflecting plate supported above the burner upon the standards 27
extending upward from the sides of the outer shells 23 and this deflector is formed
with openings 28 which register with the store holes, and if desired, these openings
can be closed by covers 29.
30 indicates the asbestos wicking which is used to start an initial fire, and when
this initial fire is thus started, the oil in the chamber 12 is vaporized and elevated
to the dome 13. From here it is drawn off by the pipe 14 and it will be seen that
there is no chance of any solid particles being drawn into the pipe 14, and in this
way all coking or charring of the hydrocarbon within the pipe is avoided. The
burners being constructed and arranged as they are, also prevent any condensation,
and as the vapour emerges from the burner it rapidly expands into the inner shell
and emerging therefrom is mixed with air and completely consumed. The covers 29
are removed when it is desired that the flames shall reach a pot &c. in the stove
hole.
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 hydrocarbon burner, an oil supply pipe, a chamber connected with said
pipe, said chamber having a lower portion provided with an inclined bottom, and a
dome shaped upper portion, a delivery pipe leading into the dome shaped portion,
and a burner pipe connected with the delivery pipe.
2. In a hydrocarbon burner, a frame comprising a base, side and top rails, a
vaporizing chamber supported upon said frame about midway its length, the burner
and pipes connecting the same with the vaporizing chamber, and the mixers
supported also from the frame above each burner, whereby the vapour is mixed
with a large percentage of air as it is burned.
3. In a hydrocarbon burner, a frame, an outer shell supported upon the same,
by means of radiating arms integral with the shell an inner shell supported upon
the outer one, the upright standards upon the outer shell and the deflecting plate
supported by said standards..
