Improvements in Blow Pipes.
I, HERBERT GEORGE KEEBLE of No. 13, Windsor Road, Denmark Hill,
in the County of Surrey, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in blow pipes, and the object of it is
to provide a portable combined lamp and blow pipe, as well as a combined
lamp, blow pipe and blast, the latter being capable of giving a flame of increased
length.
In carrying the first part of the invention into effect. I provide a suitable
lamp as the source of the necessary flaine. This lamp is, preferably, adapted to
burn methylated spirit or benzoline. In shape, the lamp is convenient for being
held in the hand and sufficiently stable to stand on a bench. The wick is presented
through a burner at the top of the lamp, the burner and wick, or both, being
adjustable in point of height. Suitable provision is made for filling the lamp, either
by using the burner socket or by making the lamp body separable about half way
of its height. The blow pipe is supported at the proper height and in a horizontal
position by a ring or guard fixed to the top of the lamp. This is open on the side
opposite the blow pipe to allow of the flame passing through to the work.
According to the second part of my invention, the lamp is fixed to the side and
near the top of a larger upright vessel or chamber, which latter is adapted to
receive the same combustible as the lamp is supplied with. The blow pipe is
supported horizontally above the said vessel, and a pipe from it dips down into the
combustible after the manner of a spray diffuser or producer. The blast through
the blow pipe sucks up a portion of the combustible from the vessel in question, and
injects it, in the form of spray, into the flame of the lamp, thereby producing a blow
pipe flame of increased length.
The blast may be supplied by the user's mouth or by any suitable type of bellows,
fixed or portable.
An adjustable chamber adapted to receive soldering fluid or flux and a brush for
applying it is also incorporated with the lamp.

Improvements in Blow Pipes.
I, HERBERT GEORGE KEEBLE, 13, Windsor Road, Denmark Hill, Surrey,
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 relates to improvements in blow pipes and the object of it is
to provide a portable combined lamp and blow pipe as well as a combined
lamp, blow pipe and blast, the latter being capable of giving a flame of increased
length and strength.

Figure 1 is a sectional elevation of a portable combined lamp and blow pipe
constructed according to the first part of my invention.
Figure 2 is a sectional elevation of a combined lamp, blow pipe and spray or jet
blast producer, whilst
Figure 3 is an elevation illustrating the general arrangement of the parts shown
and described with reference to Figure 2 and a convenient means for producing the
necessary blast.
Similar letters of reference denote like or corresponding parts in the several
figures.
Referring to Figure 1, in carrying the first part of the invention into effect
I provide a suitable lamp A as the source of the necessary flame a.
This lamp is
preferably adapted to burn methylated spirit or benzoline. In shape the lamp is
convenient for being held in the hand and sufficiently stable to stand on a bench or
other flat surface. The wick is presented through a burner at the top of the
lamp, the burner and wick or both being adjustable in point of height. Suitable
provision is made for filling the lamp, either by using the burner socket or by
making the lamp body separable about half way of its height as at c. The blow
pipe B is supported at the proper height and in a horizontal position by a ring
or guard (fixed to the top of the lamp) which may be open on the side opposite
the blow pipe to allow of the flame passing through to the work.
Referring to Figures 2 and 3, according to the second part of my invention the
lamp A is fixed to the side and near the top of a larger upright vessel or chamber C
which latter is provided with a detachable handle g and may be adapted to receive
the same combustible liquid as that with which the lamp is supplied. The blow
pipe B is supported horizontally above the said vessel C, and a pipe e depending
from the blow pipe dips down into the combustible liquid after the manner of
a spray diffuser or producer, whilst the blast through the blow pipe B sucks up a
portion of the combustible liquid from the vessel C and injects it in the form of a
spray or jet into the flame a of the lamp, thereby producing a blow pipe flame fof
increased length and strength. The blast may preferably be supplied by any
suitable type of bellows fixed or portable-the most convenient arrangement being
similar to the ordinary spray producer, as shown in Figure 3 ;-or the blast may
be produced by the user's mouth.
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
First. A portable combined lamp and blow pipe consisting of the lamp A, blow
pipe B and parts constructed, arranged and operating substantially as set forth and
shown with reference to Figure 1.
Second. A portable combined lamp, blow pipe and blast consisting of the
lamp A, blow pipe B, reservoir C and jet or spray producing tube e, the whole
constructed, arranged and operating substantially as set forth and shown with
reference to Figures 2 and 3.
