page_text: Improvements in Soldering Bits.
I, ARTHUR SHIRLEY, of Camden House, Foleshill Road, Coventry, in the County
of Warwick, Cycle Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in soldering bits provided with means by
which they are heated, the object of the invention being soldering bits adapted to
be heated by petroleum, volatile oils, gas or electricity.
A soldering bit constructed in accordance with this invention and adapted to
be heated by means of pétroleum, or volatile oils comprises a handle, adapted to
contain the petroleum or volatile oil, provided at its forward end with a tube for
conveying the oil to the burner, the said tube constituting also the shank by which
the bit is fastened to the handle. The bit is a hollow metal body preferably of
copper having a pointed or otherwise suitably shaped extremity, and furnished
around its interior, just behind the base of the point or nose, with a ring or other
burner provided with flame holes at which the oil or vapour is burned, the duct or
tube forming the shank of the tool opening into this burner after traversing part
of the body of the bit: A valve is provided for regulating the flow of oil to the.
burner, being preferably formed of a piece of pointed metal rod fitting into a
corresponding seat in the duct. The valve is opened or closed by turning the rod
which is screw threaded and which engages with corresponding screw threads in
an elbow of the said duct or pipe. The nose of the bit is provided with holes to
allow of the escape of the products of combustion.
Oil having been supplied to the reservoir (forming the handle) through a suitable
opening therein, the valve in the duct is opened by unscrewing the plug or point
from its seat so as to allow oil to flow to the burner. The oil is then lighted, and
when the body of the bit becomes sufficiently heated, the oil in traversing that
part of the duct within the hollow body becomes vapourized and burns at the ring
in the manner of a gas, combustion taking place in the hollow body of the bit
which thus becomes highly heated and the products of the combustion escape
through the holes provided for the purpose.
When using gas to heat the bit above described, the duct or tube forming the
shank is attached in any suitable manner to a flexible tube in connection with any
suitable source of gas supply. The supply of gas to the burner may be regulated in
the same manner as the oil previously described.
When the bit is to be heated by electricity the insulated conducting wires are
preferably led through the tube forming the shank to the hollow bit where the
heat may be generated by means of an arc, or by means of a suitably placed electri-
cally resistant substance, through which the current is passed.
In some cases in order to heat the burner quickly I may provide a cup like con-
trivance beneath the burner to contain oil which may be ignited readily, and thus
accelerate the production of gas in the burner. Also I may if desired attach a

page_text: pump to the reservoir or fittings for attachment of the pump thereto for putting
the oil under pressure.

I, ARTHUR SHIRLEY, of Camden House, Foleshill Road, Coventry, in the County
of Warwick, Cycle Manufacturer, 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:-
This invention relates to improvements in soldering bits provided with means by
which they are heated, the object of the invention being soldering bits adapted to
be heated by petroleum, volatile oils, or gas.
A soldering bit constructed in accordance with this invention and adapted to
be heated by means of petroleum, or volatile oils comprises a handle, adapted to
contain the petroleum or volatile oil, provided at its forward end with a tube for
conveying the oil to the burner, the said tube constituting also the shank by which
the bit is fastened to the handle.
I will proceed to more fully describe this my invention by the aid of the accom-
panying sheet of drawings, upon which are figures and numbers of reference,
similar numbers referring throughout the several views to the same thing or part,
and in which :-
Fig. 1, is a longitudinal sectional view of my improved soldering bit.
Fig. 2, is a side elevation of same, and Fig. 3, is an end view of the bit.
Fig. 4, is a cross sectional view of the bit on line A-B Fig. 1, showing the
burner.
Fig. 5, is a cross sectional view of the bit on line C-D Fig. 1, showing means
for attaching the same to the shank.
The bit 8, is a hollow metal body preferably of copper having a pointed or
otherwise suitably shaped extremity, and furnished around its interior, just behind
the base of the point or nose, with a tube or other burner 9, provided with flame
holes 10, at which the oil or vapour is burned, the duct or tube forming the
shank 11, of the tool opening into this burner after traversing part of the body of
the bit. A valve 12, is provided for regulating the flow of oil to the burner, being
preferably formed of a piece of pointed metal rod 13, fitting into a corresponding.
seat in the nozzle, 15 of the duct. The valve 12 is opened or closed by turning
the rod 13, which is screw-threaded and which engages with corresponding screw
threads in an elbow of the said duct or pipe. The nose of the bit is provided with
holes 16 to allow of the escape of the products of combustion.
Oil having been supplied to the reservoir 17, (forming the handle) through a
suitable opening 18 therein, the valve 12, in the duct is opened by unscrewing
the plug or point from its seat so as to allow oil to flow to the burner.
The oil
is then lighted, and when the body of the bit becomes sufficiently heated, the oil
in traversing that part of the duct within the hollow body becomes vapourized and
burns at the tube burner 9, in the manner of a gas, combustion taking place in the
hollow body of the bit 8, which thus becomes highly heated and the products of
the combustion escape through the holes 16 provided for the purpose.
When using gas to heat the bit above described, the duct or tube forming the
shank pipe 11, is attached in any suitable manner to a flexible tube 19, shown in

page_text: dotted lines in Fig. 2, in connection with any suitable source of gas supply. The
supply of gas to the burner may be regulated in the same manner as the onl
previously described.
In some cases in order to heat the burner quickly I may provide a cup like con-
trivance 26, beneath the burner to contain oil which may be ignited readily and
thus accelerate the production of gas in the burner. Also I may fix in the reser-
voir (as seen in Fig. 1) a fitting 21, in which there is a non-return valve 22, and
where desired I attach to this fitting a pump for putting the oil in the reservoir
under pressure.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what I
claim is:-
1. A soldering bit consisting of the hollow or chambered bit 8, being internally
heated by oil or gas from a reservoir 17 or communicating pipe 11, substantially as
described and shown.
2. The combination with the hollow bit 8, having an internal burner 9, of the
oil chamber 17, and communicating pipe 11, and nozzle 15, substantially as et
forth and shown.
3. The combination with the hollow bit 8, having an internal burner 9, of the
shank pipe 11, reservoir 17, forming a handle having the gas connection 19, all
substantially as set forth and shown.
4. In soldering bits of the kind described in preceeding claims, the combination
with the heating supply pipe 11, and nozzle 15, of the regulating valve, substan-
tially as described and shown.
