a longitudinal bore 15 opening into which
is an air port 16 which is regulated by a
perforated sleeve 17 which revolves on said
cylindrical portion 14.
5 Spaced a suitable distance from the junc-
ture of the pipe 13 with the member 14
and communicating with the bore 15, is a
gas supply pipe 18 and a pressure conduct-
0ng pipe 19, the free end of the latter be-
1o inr threaded into the base of a cone-shaped
vaive .20, the latter being rotatably mount-
ed within the valve casing 11 and held in
position by means of a screw 21 which passes
through a washer 22 and into the smaller
15 end of said valve, the washer overlying a
portion of the casing and thus causing said
valve to be tightly seated when said screw
is tightened, but allowing the same to be
rotated in the casing and upon the threads
20 -of the pipe 19, when said screw is loosened,
it being understood that said pipe 19 pos-
sesses ample flexibility to allow this move-
ment. The end of the valve 20, into which
the pipe 19 is threaded, is preferably pro-
25 vided with a knurled flange 23 by means of
which this rotation is facilitated.
As most clearly seen in Fig. 2, the valve
casing 11 is provided with a longitudinal
bore 24, the blow pipe 12 being carried by
30 the inner end thereof while a pressure sup-
ply pipe 25 is threaded into the opposite
end thereof, said pipe having its free end
located at a suitable point and normally
closed by a screw cap 26 which latter may
35 be removed when it becomes necessary to
conduct compressed air through said pipe
25 by means of a tube 27 which may lead
from any suitable source of supply. The
construction of the valve 20 is also clearly
40 shown in Fig. 2 and it will be readily seen
that the same is of hollow construction, the
pipe 19 communicating with its interior as
do the ends of the bore 24, the latter com-
munication being established through a pair
45 of openings 28, the relation of which in
respect to said bore 24, may be varied by
rotation of the valve 20, thus increasing or
diminishing the amount of pressure dis-
charged from the end of the pressure or
50 blow pipe. In the operation of this form
of the invention, gas under pressure is
passed through the tube 18 by means of a
flexible hose 29 or other suitable connec-
tion, said gas now flowing through the bore
55 15 and drawing in the proper amount of
air from the port 16, the mixture now con-
tinuing through the pipe 13, the bore 5 and
into the receptacle 1 from which it will dis-
charge through the openings 9 at which it
60 may be ignited. On account of the position-
ing of the pipe 19, an appreciable amount
of pressure will pass therethrough and into
the valve 20 from which it will be dis-
charged through the bore 24 and the blow
65 pipe 12, this pressure now acting to forcea jet of flame from the receptacle and burner
1. If it becomes necessary to increase the
pressure, discharged from the tube 12, it is
simply necessary to rotate the valve 20 in
such a manner as to increase the size of the 70
openings through which the gas may pass
it being understood that the force of the
gas passing through said openingsincreases
as the size of said openings is increased.
If it becomes necessary to provide a still 75
stronger blast for projecting the jet of flame
from the burner, the cap 26 may be re-
moved and the tube 27 applied, compressed
air being now conducted through said tube
27 and the pipe 25 into the valve casing 11 80
from which it will be discharged through
the outer end of the blow pipe 12.
It becomes expedient in the proper opera-
tion of the device, to provide means where-
by the amount of gas, fed to the interior of 85
the casing 1, may be controlled. For this
purpose I have provided a suitable valve 30
for the port 15, the latter being operated
by means of a spring actuated thumb lever
31 whose movement is limited in one direc- 90
tion by means of a set screw 32. This set
screw also serves as a means for locking the
valve in totally or partially open position,
the spring 33 holding said lever 31 nor-
mally in contact with the lower end of said 95
screw.
In Fig. 7 1 have illustrated my invention
as applied to a torch of similar construction
to the form previously described, this form
of torch being in fact, identical with said 100
previously described form with the excep-
tion that the valve mechanism, the valve 20
and the parts coacting therewith, and the
air pressure pipe are omitted, a supporting
handle 34 being attached to the upright 105
member 14. For the sake of clearness and
brevity, I have applied the same reference
numerals to the common features of the
form previously described and the form
shown in Fig. 7. 110
In Figs. 10 and 11, I have shown my im-
proved supplemental reservoir and burner
as supported by a T-coupling 10' which car-
ries a valve 35 and an air mixer 36, said
valve 35 carrying a pressure or blow pipe 115
12 which passes through the head of said
coupling, through the bore 5 and has its
free end passing through the central open-
imng 8 in the plate 7. The upper end of the
valve 35 communicates with a three-way .120
coupling 37 into which gas under pressure
is fed by means of a supply pipe 37a, the
latter being connected to a gas supply pipe
38 by means of a T-coupling 39, a valve 40
being interposed between the air mixer 36 125
and said - coupling 39. It is to be under-
stood that gas, flowing into the coupling 37
will be discharged through the pipe 12. A
portion of this gas however, flows through
a valve 41 and is discharged from the in- 1300
