Brazing and other Purposes.
We, THOMAS WILLIAM HORTON, of 4; Bennetts Hill, Birmingham, in the County of
Warwick, Solicitor, and WILLIAM PULLEN, of 51, Holloway Head, Birmingham afore-
said, Brush and Art Metal Dealer, do hereby declare the nature of our said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
Our invention has for its object a new or improved portable apparatus or tool for
brazing and other purposes which will be found very handy as it can easily be
manipulated in various positions and can be used with ordinary paraffin or petroleum oil.
In order that our invention may be clearly understood and easily carried into
practical effect we have appended hereunto two sheets of drawings upon which we
have illustrated examples of our improvements.
Figure 1 is a part sectional perspective view of our portable apparatus or brazing
tool.
Figure 2 is a detail view of the vapouriser and burner.
Figure 3 is a modification showing the burner and vapouriser combined.
Figure 4 is another modification of a combined vapouriser and burner showing a
method for regulating the supply of oil.
In carrying our invention into practice we provide the oil container A which may
be of any size and shape. Fitted into this container is the pump B which pumps air
into the container, thereby forcing the paraffin oil up the pipe C which is attached
to one end of the flexible tube D secured to the top of the tank by the lock nut d¹.
This pump is provided at the nozzle with the valve b¹ which opens by the pressure of
air and is closed by the action of the spring b². The plug 63 is provided as a stopper
for the opening through which the container is refilled. The other end of the .
flexible tube is attached in any desired manner to one end of the stop cock E, the
other end of this cock being fixed to the combined handle and bracket or burner
nozzle holder F. The handle portion of this bracket is hollow covered on the exterior
with asbestos string or other non- conductor of heat, and passing down this hollow
handle is the tube h¹ communicating at one end with the stop cock; the other
portion of this tube is then formed into the coil H in such a manner that the part h³.
crosses the coil at the point where the flame issues the other end h* being situated
between the coil and the hollow handle and on this end of the tube we fix the
burner. This coil H which we call the vapouriser is covered or enclosed by the
burner nozzle J which fits into the holder F. If desired we may fix the cup K
between the holder F so as to partly enclose the burner for the purpose of holding
methylated spirits for heating the coil when starting the apparatus. The bracket or
burner nozzle holder may be formed at an angle instead of straight as shown. .

page_text: At Figure 3 we have shown a combined coiled vapouriser and burner nozzle which
is made by forming the coils H³ tapered towards the top or end from which the flame
issues.
In the method as shewn at Figure 4 we form the combined vapouriser and burner
nozzle from the bell mouthed piece L with an annular space formed so as to
constitute an annular jacket for the oil and vapour. The oil passes into the space
at 12 and out to the burner through the pipe or hole 13. The bar or grid / which
may be formed of one or more bars is provided for the flame to impinge against as it
issues from the mouth. The arrangement for controlling the supply of oil, which
may be fitted into the handle of the apparatus consists of the lever N pivotted to the
support n at about the centre and to the valve spindle p¹ which is connected to the
valve P. When the end n of the lever is depressed it lifts the valve from its seating
and thus allows the full rush of oil to pass through, but as soon as the lever is
released the spring p² forces the valve on to its seating and cuts off the full supply of
oil, only allowing sufficient to pass to keep the burner alight for heating the
vapouriser.
The action of our apparatus is as follows:-
A supply of air is first pumped into the container, which is full of petroleum or
paraffin oil, and then the cup K is filled with methylated spirits and ignited so as to
heat the coil, or the coil may be heated by other means and when sufficiently heated
the cock E is opened and if the controlling arrangement as shown at Figure 4 is used
the lever is pressed, thus allowing the oil which is forced upwards.by the pressure of
air to freely flow into the heated coil, where it immediately becomes vapourised or
converted into gas and is ignited as it issues from the burner through the interior of
the coil, striking against the cross piece and out at the mouth of the burner.
In some cases we may dispense with the pump in the oil container and pump the
oil into the container from an independent barrel or supply tank, the oil being forced
up the flexible tubing by the air in the container as it becomes filled with oil.
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
:-The combination and arrangements of the various parts constituting a port
able apparatus or tool with its flexible connection, for brazing and other
the
purposes substantially as herein described and as shewn upon
accompanying sheets of drawings.
nd: In a portable apparatus or tool for brazing and other purposes a coil
situated in the interior of the burner nozzle and in contact with the flame for
vapourising and converting the oil or vapour into gas in the manner substan-
tially as herein set forth and as shown upon the accompanying sheets of
drawings.
d-In a portable apparatus or tool for brazing and other purposes the handle
covered with asbestos or asbestos string or other non-conductor of heat,
and forming part of the frame for enclosing the coil or vapouriser and for
supporting the burner nozzle in the manner, and for the purpose substantially
as herein set forth and as shown upon the drawings.
th-In a portable apparatus or tool for brazing and other purposes the frame
for enclosing the coil or vapouriser and for supporting the burner nozzle in the
manner and for the purpose substantially as herein described and as shown
upon the drawings.
:-În a portable apparatus or tool for brazing and other purposes such as
previously claimed forcing the oil out of the container by an air pump located
in the interior of the container in the manner substantially as herein set forth
and as shewn upon the drawings.
