COMPLETE SPECIFICATION.
Improvements in Vapour Burners or Plumbers' Torches.
I, CHARLES HUTCHINSON THOMPSON, Gentleman, of 39 West 27th Street,
New York City, in the County and State of New York, United States of America,
do hereby declare the nature of my invention for "IMPROVEMENTS IN VAPOUR
BURNERS OR PLUMBERS' TORCHES," 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 the invention is to provide an improved device for producing a
flame for removing paint and the like and for plumbers' use, and the invention
consists in the novel construction hereinafter described.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a plan view of a burner or torch embodying my invention, the handle
being partly broken away and the mixing tube being shown in section on line 1, 1,
Figure 2; and
Figure 2 is a vertical section on line 2, 2, Figure 1.
In constructing a torch or burner in accordance with my invention, the body or
reservoir a is made of the desired size for containing a sufficient supply of gasoline,
and of suitable shape, preferably cylindrical, and at two or more points on its
exterior sockets b are provided, either one of which is adapted to receive the
handle c.
The gasoline is supplied through a suitable orifice which is closed by a
screw plug d.
At the top, near the edge, the body is formed with a raised neck e internally
threaded, which receives the wick tube f, into which a wick g is tightly fitted, the
wick being of a length to reach to near the bottom of the reservoir and to near
the top of the wick tube f. The top of the wick tube f is closed by a suitable
tip h having an axial orifice i for outlet of the vaporized gasoline and a transverse
groove at the inner end; said groove in practice has been found efficient in
preventing clogging of the axial outlet and thereby increasing the efficiency of the
burner.
In connection with the wick and wick tube, a vapor tube k is employed, and
extends from the neck e downward to near the bottom of the reservoir, and is then
returned on itself and extended upward into the wick tube f to near the tip h,
thereof, the vapor tube k being spaced from the wick tube sufficiently to accom-
modate the wick g, and the arrangement is such that vapor will be conducted from
the reservoir above the gasoline through tube k to the tip of wick tube f and
increase the intensity of the flame. The bend of the vapor tube passes around
and is soldered or otherwise suitably secured to a cross bar m and said cross bar is
a sufficient distance above the bottom to prevent injury to the bar and a consequent
displacement of the vapor tube in the event the bottom should become indented.
Around the wick tube f there is fitted a mixing tube n which, near the bottom,
is provided with an exterior cup-shaped flange o adapted to receive a sufficient
quantity of gasoline to heat the wick tube and wick and start the generation of the
vapor, the parts once heated supplying sufficient vapor to sustain the flame.
mixing tube n has suitable side openings p, for the entrance of atmospheric air to
mix with the vapor from the wick and vapor tube.
The
It will be observed that the wick tube and its appurtenances are inclined to the
vertical so as to direct the flame outward from the device. At the inner end of
the top a gauze disk is provided and has been found efficient in practice.

page_text: 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,-
1. The improved torch or burner constructed and operating, substantially as
shown and specified.
2. The combination with the reservoir and wiek tube, of the vapor tube so
constructed and arranged as to conduct vapor from above the gasoline in the
reservoir to the wick tube, substantially as described.
3. The combination with the reservoir and wick tube, of the mixing tube
having a cup-shaped flange for receiving a quantity of gasoline, substantially as
described.
4. The improved torch or burner comprising the reservoir, the wick tube and
the vapor tube, said vapor tube being supported by a cross bar above the bottom
of the reservoir, substantially as described.
5. The wick tube having a tip formed with an axial orifice and with a transverse
groove at its inner end, substantially as described.
6. The wick tube having a tip formed with an axial bore, and a gauze disk at
the inner end of the tip, substantially as described.
Dated this 26th day of July 1894.
