Improvements in Gas or Vapour Burners.
"I, HARRY MCMILLEN HAMRICK, of No. 802, Witherspoon Building, Philadelphia,
Pennsylvania, United States of America, Mechanical Engineer, 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 an improvement in burners, whereby the flame from
the same is projected against the generating tube so as to heat the same.
It further consists in providing a generator and conductor in which the hydro-
carbon is converted into vapor or gas, and the heat conducted to a chamber and
thence into the burner tube.
It further consists of novel details of construction, all as will be hereinafter
set forth.
In the accompanying drawing,
Figure 1 represents an elevation of a burner, embodying my invention.
Figure 2 represents a vertical sectional view on line - Figure 1.
Figure 3 represents an elevation of a cap employed, showing perforations
therein, and
Figure 4 represents a vertical sectional view of a portion of the tube employed
without the use of the cap.
Similar letters of reference indicate corresponding parts in the figures.
A designates a burner, the same consisting of a tube B having the flaring
end C and having the bars D) which are suitably secured to said tube, and to
the casing or plug E, which latter is screw-threaded in order to be secured to
the place of support and is provided with a chamber F, having the outlet or
passage G leading therefrom.
H designates a cap which is adapted to be placed on the upper end of said
tube B, between which and said cap are situated the screens or gauzes J, said
cap having slots K above said screens and being provided at or near its mouth
with a screen or gauze L, said screens being held in position by any suitable means.
M designates a supply pipe which leads from any suitable source of supply
(not shown) and conducts the hydro-carbon to the generator tube N, which is
adjacent to said tube and passes up the same and around the cap H at about a
level with the slots K, through which the flame is adapted to pass and heat said
generator, which serves to conduct the heat to the plug E, since said generator
passes down said tube and communicates with the chamber F in the plug E.
I designates a screen which is placed around the cap and covers the perforations
or slots, so that the flame which issues therethrough may be steadied.
A suitable pin valve Q or analogous device is conveniently situated in order
to control the supply of hydro-carbon as desired.
In lieu of the slots L in the cap H, I may employ the perforations R, the
effect being the same, and I may dispense with said cap H and seat the screens J
directly within the tube B seen in Figure 4, in which event I will provide perfora

tions S in the tube B above said screens, and above said perforations will be
placed the gauze or screen L, the effect being the same.
V designates a mantle which is supported above the burner by the rod or bar W,
which is removably supported in a lug A¹ by a set screw B¹.
The operation is as follows:
The hydro-carbon passes through the tube M into the generator N; the amount
being adjusted by the valve Q, and passes up the generator and around the same,
where the burner having been lighted, flames will play against the generator
and the hydrocarbon will be converted into vapor or gas, and passes down the
generator into the chamber F from which it is forced through the outlet G, and
into the tube B, where it mingles with the air and passes through the screens and
is ignited. The screen L serves to cushion enough of the flame to be thrown
through the openings in the cap.
It will of course be evident that the advantage of employing the cap is that
by removing the same access to the screens can be readily had and the same
replaced if worn or broken, and this is the preferred form, but as above
stated, the screens may be placed directly in the tube, and the cap dispensed with.
It will of course be evident that various changes may be made in the con-
struction without departing from the spirit of my invention, and I do not
therefore desire to be limited in every instance to the form as herein shown and
described.
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. In a burner, a tube, a chamber and a generator, which is adapted to be
heated by the flame of said burner and conducts the heat to said chamber.
2nd. In a burner, a tube having openings therein, a generator adjacent to said
openings, and means for forcing a flame against said generator.
3rd. In a burner, a tube having openings therein, a screen covering said open-
ings, a generator adjacent said openings and means for forcing flames against said
generator.
4th. In a burner, a tube having perforations or openings in the side thereof,
a generator adjacent said openings, a chamber communicating with said generator
and a sereen above said openings, whereby a flame is projected against said
generator.
5th. In a burner, a tube, a cap therefore having openings therein, a screen
above said openings, a screen below said openings, a generator adjacent said
openings, and a chamber with an outlet in communication with said generator.
6th. In a burner, a tube, a chamber with an outlet below said tube, a cap for
said tube having openings in the side, screens above and below said openings, a
generator passing upwards and around said cap and down and communicating with
said chamber and means for regulating the supply of hydro-carbon.
