1, HERMAN BUSH, Jeweller's Agent, of 125, Hessle Road, Hull, in the county of
York, do hereby declare the nature of this invention to be as follows:-
My invention of Improvements in "Combination Lamp and Blow-Pipe" refers to a
combination of an ordinary small lamp with a specially constructed apparatus of a
blow-pipe of simple construction and handy form, increase of power and range of
flame over similar contrivances previously introduced by me, and designed for use by
various metal-working trades for soldering or annealing.
The apparatus consists of a metallic vessel of cylindrical shape 31 inches high and
the same or more in diameter, internally divided into two sections; one of the sections
forming an oval tube of 14 by 2 inches diameter and 2 inches high, one end of this
tube is securely soldered to the inside of the lid of the vessel and the other end fitted
with a bottom securely soldered. On the lid of the vessel over the said tube is made a
hole into which is fitted and securely soldered the outer screw-rim of an ordinary
small benzoline lamp to hold the burner and wick with an attachement for raising and
lowering. This section or compartment is intended to hold the fuel of the ordinary
lamp and consists of equal parts of Methylated Spirits and Benzoline or Gasoline,
which propelled by a wick gives bright light without smoke and no disagreeable smell,
this section or division is placed in the interior of the body of the vessel at the side of
the lid; the remaining space of the body of the vessel, forming the other section is
intended to hold the fuel for furnishing the flame or heat of inflamable gas for
soldering, annealing or other heating purposes is Gasoline or Ligroine.
The centre of the lid carries a slightly conical tube about half an inch in diameter
at the bottom and about 14 inch high, having at the side in a line with the wick of the
lamp, near the top end a hole of one-eighth inch diameter; the lid of the vessel is
pierced for the reception of the conical tube in order to extend the opening into the
body of the vessel, whilst the top end of the conical tube is closed up by a disc of
metal plugged in and securely soldered. The upper end of this conical tube carries a
closely fitting and revolving ferrule into which are horizontally soldered at equal
distances three tubes of one-eighth inch diameter with orifices of different sizes; the

page_text: sufficient for soldering the largest lead, brass or iron pipes, joinings or defective places.
The blow-pipe will answer for melting moderate quantities of gold and silver, without
recourse to crucible or fire, or for testing mineral substances or native ores or alloys
for precious metals, likewise for soft as well as hard soldering metallic articles
generally manufactured or repaired by various metal working trades, or serve, without
the use of the blow-pipe, as an ordinary sinall lamp on the work-bench or in dark
chambers.
2. Simpler construction and more handy form of the apparatus in general,
and lower rate of manufacture than similar contrivances of soldering lamps and
blow-pipes.
3. Increase of heating power and range of flame by forcing a large volume of air
through the cross cuts in the spiral windings thereby generating a maximum quantity
of oil-gas to produce the beating power and likewise utmost security against unavoidable
accidents by guarding the rotating ferrule against removal from the conical tube, not
otherwise to be avoided.

page_text: I, HERMAN BUSH, Jeweller's Agent, of 125, Hessle Road, Hull, in the County of
York do hereby declare the nature of my invention for AN IMPROVED COMBINATION
LAMP AND BLOW PIPE and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :-
My invention of "Improved Combination Lamp and Blow-Pipe" refers to a com-
bination of an ordinary small lamp with a specially constructed apparatus and attached
blowpipe of simple construction, pleasing and handy form, giving an increase of power
and range of flame over similar contrivances previously introduced.
The apparatus consists of a metallic vessel A of cylindrically corrugated shape
34 inches high and about the same in diameter, internally divided into two sections;
one of the sections forming an oval tube of 14 and 21 inches diameter, B and 2 inches
high. One end of this tube is securely soldered to the inside of the lid of the vessel
and the other end fitted with a bottom securely soldered. On the lid of the vessel over
the said tube is a hole into which is fitted and securely soldered the outer screwing of
an ordinary small benzoline lamp to hold the burner and wick with an attachement for
raising and lowering, C. This section or compartment is intended to hold the fuel of
the ordinary lamp and consists of equal parts of methylated spirits and gasoline, which,
propelled by a wick gives bright light without smoke or disagreeable smell. This
section or division is placed in the interior of the body of the vessel at the side of the
lid, the remaining space forming the other section intended to hold the fuel for
furnishing the flame or heat of inflamable and ignited gas for soldering, annealing or
other heating purposes, gasoline.
On the top of the lid of the vessel and opposite the burner of the lamp is a hollow
projection in appearance similar to the body holding the burner, which serves as an
accumulator or condenser of the gas serving as the heating modium D. The top of
this projection carries a slightly conical tube about 1 inches high and inch in
diameter at the bottom, E, having at the side in a line with the wick of the lamp near
the upper end a hole of about of an inch in diameter; the lid of the vessel is pierced
for the reception of the named projection carrying the conical tube in order to form
an open connection with the body of the lamp, whilst the top end of the conical tube
is closed up by a disc of metal plugged in and soldered. This conical tube is enclosed
in a well fitting and rotating ferrule, F, into which are soldered in a horizontal position
at equal distances into holes corresponding the hole of the inner tube three tubes, of
inch diameter and of G G G a length to reach nearly to the wick of the opposite
burner, each of these tubes with an orifice of a different size. The revolving ferrule is
secured against removal from the conical tube by a metal cap covering H the circum-
ference of the ferrule, but fastened by means of screw or solder to the top of the conical
tube, which arrangement will prevent any possibility of escape of gas and afford
security against accidents not otherwise to be avoided. At the side of the lid on the
top of the vessel and between the burner of the lamp and the conical tube is a hole
fitted with a screw stopper forming the mouth of the vessel M for feeding the body

page_text: with the fluid for generating the gas. Under this hole attached to the inside of the
corrugated side of the vessel is a contrivance in the shape of a float made of a slice of
cork, L suspended on a wire sliding up and down in a piece of thin tubing, which
prevents the overfilling of the vessel with the fluid, as the suspended cork begins to
brise when it is reached by the fluid poured into the vessel, exhibiting a red glass
ball attached to the upper end of the wire as a warning to stop.
Opposite the hole for feeding the vessel and likewise between the burner of the lamp
NN and the conical tube is a hole to receive a metal tube of inch diameter. This
tube is first of all bent into a horizontal spiral winding provided on the upper side at
about half inch distances with incisions by a fine piercing saw. The inner end of the
spiral winding tube is plugged and soldered up. The flat spiral winding rests on
the bottom of the vessel, covering Fig. 3 about ths of its space and the outer end of the
spiral winding is bent at right angle upwards and extends about inch out of the K
intended hole on the lid of the vessel and is bent slightly outwards. On to this end is
fitted an india rubber tube about 12 inches long, O provided with a mouthpiece of
hone, having a curved plate of tin as a rest against the lips or a smaller plate to serve
as a rest against the teeth in the mouth of the operator, P.
The metal tube, on to which the india rubber tube is fitted, is securely soldered into
the hole on the lid of the vessel out of which it protrudes. In the inside of the vessel
just under the bottom of the oval tube forming the body of the lamp is a circular plate
perforated with fine holes and a hole for admitting the upright end of the spiral
winding and is intended to promote the generating of the gas for heating. This plate
fits well into the vessel on to which it is soldered, Fig. 5. The bottom and the lid are
securely soldered on to the corrugated edges of the side, so as to make the apparatus
compact and air-tight.
Directions for using the "Improved Combination Lamp and Blow-Pipe." Unserew
the head of the lamp holding the wick and nearly fill with a mixture of gasoline and
methylated spirits and adjust the head of the lamp in its place; then remove the screw
stopper and fill with gasoline until the red glass ball ceases rising, adjust the screw
stopper firmly and light the wick of the lamp, turn the ferrule on the conical tube so
as to bring the orifice of any of the required sizes of horizontal tubes over the ignited
wick, which is raised or lowered according to the size of the orifice to meet it, take the
mouthpiece of the india rubber tube into your mouth and blow into it, when the air
escaping out of the cuts in the spiral winding at the bottom of the vessel will generate
gas from the gasoline and be accelerated in the generating by passing through the
perforations in the circular plate and in ascending condense in the accumulator, pass
through the conical tube and side hole, entering the horizontal tube of the rotating
ferrule before it and at the orifice the issuing gas will instantly ignite at the flame of
the wick into a solid and powerful flame, which, being directed on to the place of the
article to be soldered or heated, will produce a heat of unquestionably the nearest
approach of coal gas not to be obtained by any similar contrivance and at such insigni-
ficant expense. After done using the blow pipe, the flame will instantly cease, then turn
the ferrule sidewards in order to prevent the escape of unutilized gas, and lower, if
desirable, the wick, which will keep the apparatus ready for operation without
relighting.
For any work of a regular nature to be conducted on the work bench, some
mechanical blower, instead of blowing with the lungs will do good sorvice and can
easily be arranged with the requisition of a common house bellows fastened under the
bench and connected with the india rubber tube of the apparatus and worked either by
hand or with a foot pedal, if for the latter purpose a sofa spring is placed between the
handles, so as to render the opening automatic, when the pressure of the foot on the
movable top board of the bellows will give the blast instead the lungs.
The "Improved Combination Lamp and Blow-Pipe" possesses numerous advantages
over similar blow pipo apparatuses hitherto in use, as its function can be set instantly
into action without any previous preparation and will admirably answer the require-
ments of plumbers and gasfitters, jewellers and watch-makers, various metallic
instrument makers, assayers, mining prospectors and chymical manipulators.
