PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Blow-pipes, and in Burners to
be Used in connection therewith.
We, JOSEPH SMITH and JAMES ROSCOW SMITH both of 72 Halliwell Road,
Bolton in the County of Lancaster, Brazing-apparatus Manufacturers, do hereby
declare the nature of this invention to be as follows, that is to say :-
It relates to improvements in blow-pipes (for brazing or other purposes) and in
burners to be used in connection with these blow pipes and consists of constructing
same so that the blast of air discharged from or fed to the flames by them may be
either cold or heated, while the burners used in connection with these blow pipes
are adapted in accordance with one arrangement for utilizing oil as the flame
producing substance or medium and in accordance with another arrangement these
burners are made to answer their purposes whether oil or gas is used.
In carrying our invention into effect we construct the blow pipe so that that part
of it near the orifice whence the air emerges passes through a flame which will
thus heat said air prior to its contact with the flame, and to have in a given space
as great a surface of said part of the pipe as possible, heated by said flame we bend
or coil same to meet the necessary requirements.
The burners for use in connection with these blow pipes are made of sheet metal
or other material and are mounted in suitable proximity with the orifices from
which the jets of air emerge, openings being made vertically in these burners so
that the flames therein may ascend when the blasts are not being applied, while
lateral openings are made of a suitable form in order that the blasts when acting
may carry the flames as desired.
Leading into these burners are pipes which supply the oil from any suitable
vessels either arranged to be held in the hands of the workmen or users or to be
fixed and to act as stationary supply tanks, appropriate valve-mechanisms being
applied thereto so that the flow of the oil is thus brought directly under the control
of the users.
We fix a receptacle in a suitable position relative with the burner, so that any
stray oil may be caught by it and thus prevented from running to waste.
When the burners are to be used for either oil or gas, the pipes for supplying
the latter are arranged to do so without interfering with the construction of these
burners or their functions as oil burners, and this may be effected by making the
gas-supply pipe encircle the outer end of the blow-pipe which enters the burner
above described.
We preferably use a burner with each blow-pipe although we may for certain
purposes use several blow-pipes to one burner, or a series of burners and blow-pipes
may be attached together.
The blast may be supplied from any of the well known bellows, fans or other
blowers, while the whole apparatus may be mounted on fixed bearings or made so
that it may be held in the hands of the user.
In order to guide or concentrate the blast or current of air a guiding lip or
nipple is mounted within or attached to the blow-pipe at or near its orifice.

page_text: Improvements in or appertaining to Blow-pipes, and in Burners to
be Used in connection therewith.
We, JOSEPH SMITH and JAMES ROSCOW SMITH, both of 72 Halliwell Road,
Bolton in the County of Lancaster, Brazing-apparatus Manufacturers, 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,
that is to say :-
It relates to improvements in blow-pipes (for brazing or other purposes) and in
burners to be used in connection with these blow-pipes and consists of constructing
same so that the blast of air discharged from or fed to the flames by them may be
either cold or heated, while the burners used in connection with these blow-pipes
are adapted in accordance with one arrangement for utilizing oil as the flame
producing substance or medium and in accordance with another arrangement these
burners are made to answer their purposes whether oil or gas is used.
In order that our said invention may be more readily understood, we have
hereunto appended sheets of drawings illustrative thereof, in which :-
Figs. 1 and 2 are side elevation and top view respectively of apparatus made in
accordance with our said invention.
Fig. 3 is a part sectional elevation of our said improved apparatus.
Figs. 4 and 5 are side sectional and end views of certain parts of our said
invention and are drawn to an enlarged scale in order that their formation or
construction may be more readily understood.
Figs. 6, 7, and 8 are part sectional elevations of modifications hereinafter
described.
Similar letters and figures refer to similar parts throughout the several views.
In carrying our invention into effect we construct the blow-pipe a so that that
part of it a near the orifice a³ whence the air emerges passes through a flame which
will thus heat said air prior to its contact with the flame, and to have in a given
space as great a surface as possible of said part a¹ of the pipe a heated by said
flame we bend or coil same as shown at a³ Fig. 6, to meet the necessary require-
ments, although for most purposes the formation illustrated by the several other
views answers all that is desired.
The burners b for use in connection with these blow-pipes, are made of sheet
metal or other material and are mounted in suitable proximity with the orifices a
from which the jets of air emerge, openings c being made vertically in these
burners so that the flames therein may ascend when the blasts are not being
applied, while lateral openings d are made of a suitable form in order that the
blasts when acting may carry the flames as desired.
In order to guide or concentrate the blast or current of air a guiding lip or
nipple k is mounted within or attached to the blow-pipe a at or near its orifice a..
Leading into these burners bare pipes e which supply the oil from any suitable
vessel or vessels feither arranged to be held in the hands of the workmen or users
(which arrangement is the one shown in the drawings wherein Figs. 1 and 3
illustrate the apparatus as in position as on a table or on the floor in which the oil
is prevented from flowing out of the tube e) or to be fixed and to act as stationary
supply tanks, appropriate valve mechanism g being applied thereto so that the
flow of oil is thus brought directly under the control of the users.
We fix a receptacle in a suitable position relative with the burner b, so that
any stray oil may be caught by it and thus prevented from running to waste.
When the burners b are to be used for either oil or gas or for both, the pipes for
supplying the latter are arranged to do so without interfering with the construction
of these burners or their functions as oil burners and this may be effected by

page_text: making the gas supply pipe e' encircle the outer end of the blow-pipe a (as shown
by Fig. 7) which enters the burner b above described.
Provided the apparatus will meet the necessary requirements if fixed to a
stationary object as the wall of a building or the like, then the oil supply pipe e
and the air pipe a may be arranged relatively with each other and the parts b
and 6 in which case also the cone 6' may be detachable if desired, as shown by
Fig. 8.
We preferably use a burner b with each blow-pipe a although we may for
certain purposes use several blow-pipes to one burner, or a series of burners and
blow-pipes may be attached together.
The blast may be supplied from any of the well known bellows, fans or other
blowers, while the whole apparatus may be mounted on fixed bearings or made so
that it may be held in the bands of the user.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination in blow-pipes of air and oil supply pipes with shields and
valves for guiding and controlling same substantially as herein specified.
2. The combination in blow-pipes of air, gas and oil supply pipes with shields
and valves for guiding and controlling same substantially as herein specified.
3. The combination in blow-pipes of the air and oil supply pipes, shields and
valves for protecting and controlling the flow of same, and a receptacle for
preventing the waste of stray oil substantially as herein specified.
4. The combination of the several parts forming blow-pipes, the same being
constructed and arranged substantially as herein specified.
