'Improvements in Vapour Burners."
I, HARPER FORREST SMITH, of 3226 Montgomery Avenue, Philadelphia,
Pennsylvania, United States of America, Mechanician, 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:—
My invention consists of improvements in vapour burners embodying means for
vaporizing the gasoline or hydro-carbon fluid employed, and converting the same
into gas in a practical and efficient manner, the features of the same being
hereinafter described.
In the accompanying drawing
Figure 1 represents a vertical section of a vapor burner embodying my
invention.
Figures 2 and 3. represents vertical sections of other forms thereof.
Similar letters of reference indicate corresponding parts in all the figures.
A designates the vapor tube to which is attached the pipe which supplies gasolina
or other hydro-carbon fluid to said tube.
B designates a smaller vapor tube or passage which extends obliquely in the shell.
of the device from the tube A to the chamber C of the needle valve D, which may
be raised and lowered or adjusted by the screw stem E of said valve.
Directly above said valve is the gas tube F, whose lower end is open to the
atmosphere, whereby air may be admitted into said tube by the action of the vapour
directed from said valve into the open end of said tube.
On the side of the tube is the small port G, which forms a direct com-
munication between said tube and the superheating tube H, which is located
above or adjacent to the vapour tube A, so that gas will be directed into said 'tube.
A and discharge from said tube H, which when ignited serves to superheat the
tube A.
Supported on the tube F' is the burner J, at the sides of which are the flaring
armis K, and in said tube opposite to said arms are the ports L, through which gas
is discharged for heating said arms and increasing the temperature of the gas in
the tube F.
Rising from the tip of the burner are the deflectors and guards M, which protect
the resultant flame, and act as an additional heater for said tip, preventing
carbonization in the slit or opening of the tip, especially as after the flame is
extinguished there is a retention of heat for a considerable time.
It will be seen that when the device is in operation, as the tube A is heated by
the flame of the superheating tube, the gasoline or hydrocarbon fluid that enters
said tube A is vaporized, and the vapor passes through the tube B, and enters the
valve chamber from which it is directed into the tube F, and air is also admitted
at the open bottom of the same, whereby a highly inflammable gas is produced,
some of which enters the superheating tube as has been stated, and the remainder
may be consumed at the tip of the burner, where the flame will be brilliant and of
a high temperature.

page_text: In order to admit the air into the superheating tube H to be combined with the
gas therein for governing the blueness of the flame and intensity of the heat on
the tube A, said tube H is provided with an opening N for this purpose as shown
in the drawing.
In Figure 2, the communication between the tube A and the valve chamber is
by means of a passage or tube Q, which extends parallel with said tube A instead,
of obliquely as in Figure 1, and the gas tube F is closed at its bottom, and provided
just above the same with an opening or inlet R for the admission of air to the gas
in said tube F.
In Figure 3, both tubes B and.Q of Figures 1 and 2, are dispensed with, and the
tube A communicates directly with the valve chamber.
In this case the gas tube is directly connected with the valve chamber, and
provided with an air inlet P, as in Figure 2. In the said figure 3 the superheating
tube is also omitted, it being noticed that the vapour tube A is close to the burner,
the latter being heated by the flame of the gas discharged through the ports L
adjacent to the arms K, which receive the impact of said flame.
I am aware that it is not new to connect a pipe with the burner, the same.
extending from said tube outside of the same, to the superheater tube or chamber,
so as to supply the latter with gas for primarily superheating the hydro-carbon fluid
in the supply tube, but in my construction, I employ the port G as a direct
communication between the tubes F and H, and thus avoid the use of the aforesaid
pipe.
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:-
1st. A vapour, burner consisting of a shell having therein a vapour chamber with
an inlet and an outlet, a controlling valve for said outlet, a gas passage open to
the atmosphere directly over said vapor chamber outlet and in line therewith and
a superheating passage adjacent and over said vapour inlet passage and provided
with an air inlet and communicating directly with said gas passage, and a tip
connected with said shell.
2nd. A vapour burner consisting of a shell having the vapour chamber C with
the needle valve D therein and provided with the inlet A and communicating
passage B, the gas passage F open at its base directly over the vapor chamber outlet
to the atmosphere, said gas passage being in line with said vapour chamber, tha
superheating tube H adjacent to and above said inlet and communicating directly
with said gas passage, and a tip secured to said shell.
Ord. A vapour burner consisting of a shell having the chamber C with the valve
1) therein, the inlet A, the passage B, the gas tube F, the superheating tube H,
adiacent to and over said inlet and communicating directly with said gas tube,
a tip ou said shell, the arms K and guards M.
