page_text: PROVISIONAL SPECIFICATION.
I THOMAS BRIGGS of 58 Rokeby Street, Stratford, in the County of Essex,
Plumber, do hereby declare the nature of my said invention for "APPARATUS FOR
USE IN SOLDERING," to be as follows:-
It is well known that in making plumber's wiped & other kind of joints, a fire
is required to melt the metal, & to heat the irons, & that moreover the use of this
fire in certain places is attended with a great risk owing to the liability of setting
fire to the place. The number of buildings that have been destroyed by this
agency is proof of the great risk incurred by the use of these plumber's fires.
The object of my invention is to provide an apparatus by the use of which all
kinds of plumber's joints may be made without the use of fires, melted metal, or
heated irons, & consists in the use of an apparatus producing a fierce flame, hot
enough to heat the work, & melt the solder, & in every way sufficient to produce
first class work.
The apparatus to produce this flame is constructed as follows;-I take an air
tight vessel of suitable dimensions according to the sized apparatus required & in
it I fix a small piston air pump provided with a suitable handle on the outside to
manipulate it; this air pump has two valves in both the suction & the deliverey
pipe, each of which has a port at each end of the pump barrel, so that the pump is
a continuous acting one, charging & delivering during each stroke.
The suction pipe communicates with the outside of the vessel. The delivery
pipe is contained entirely within the vessel which acts as a reservoir for the
compressed air. The end of the delivery pipe is coiled on the bottom of the vessel,
& it is perforated with numerous small holes. On the top of this coil a quantity
of cotton wool, waste, or other absorbent material is placed say sufficient to occupy
one eight of the capacity of the vessel. This material is to absorb the petroleum
or other gaseous oil which is placed in the vessel, so that none of it is loose, thereby
avoiding the liability of it leaking. A suitable trapped opening is provided in the
top of the vessel to allow the oil to be introduced. It will be seen that if the
vessel is charged with oil, & the pump set to work it will be filled with a gaseous
compressed air. An outlet pipe is provided in any suitable part of the vessel, & it
is fitted immediately outside the vessel with a cock. To the end of this pipe an
india-rubber tube of any desired length is fixed; to the other end of this rubber

page_text: tube is fixed the manipulating nozzle, which consists of a tube of about of an
inch dia. bent in the form of an elbow, from the top of this pipe another one of
about of an inch dia. is lead, & passing through the top of the other pipe just at
the bend is carried inside the large pipe to within a short distance of its end,
which therefore presents the appearance of an injector, being one small pipe within
a large one. Both these pipes are provided somewhere in their length with cocks
placed so as to be convenient for manipulation.
To set the apparatus to work the reservoir is charged with air, & after the cock
on the outlet pipe, & also the cock on the large pipe at the end of the nozzle are
opened, a light is applied to the nozzle when a flame will appear, which may be 1
intensified to any degree by opening the cock of the small pipe at the nozzle, so as
to let the compressed air at a greater pressure play on the flame.
It will be understood that the pressure must be kept up in the reservoir by
constantly keeping the pump at work, which may be effected by either hand
or foot,
Several nozzles may bo fed from one reservoir and pump;

I THOMAS BRIGGS of 58 Rokeby Street, Stratford in the County of Essex,
Plumber, do hereby declare the nature of my said invention for " APPARATUS FOR
USE IN SOLDERING and in what manner the same is to be performed, to be
particularly, described and ascertained in and by the following statement :-
It is well known that in making plumber's wiped and other kinds of joints,
a fire is required to melt the metal, and to beat the irons, and that moreover the
use of this fire in certain places is attended with a great risk owing to the liability
of setting fire to the place. The number of buildings that have been destroyed
by this agency is proof of the great risk incurred by the use of these "plumer's
fires.
The object of my invention is to provide an apparatus by the use of which all
kinds of plumber's joints may be made without the use of fires, melted metal, or
heated irons; and consists in the use of an apparatus producing a fierce flaine,
hot enough to heat the work, and melt the solder, and in every way sufficient to
produce first class work.
The apparatus to produce this flame is constructed as follows;-I take an air-
tight vessel of suitable dimensions, according to the sized apparatus required, and
in it I fix a small piston air pump provided with a suitable bandle on the outside
to manipulate it; this air pump has two valves in both the suction and the
delivery pipe, each of which has a port at each end of the pump barrel, so that
the pump is a continuous acting one, charging and delivering at each stroke.
The suction pipe communicates with the outside of the vessel. The delivery pipe
is contained entirely within the vessel which acts as a reservoir for the compressed
air. The end of the delivery pipe is coiled on the bottom of the vessel and it is
perforated with numerous small holes. On the top of this coil a quantity of
cotton wool or waste, or other absorbent material is placed, say sufficient to occupy
one eigth of capacity of the vessel. This material is to absorb the petroleum
product, benzoline or othe gaseous oil or spirit which is placed in the vessel, so
that none of it is loose, thereby avoiding the liability of it leaking. A suitable
trapped opening is provided in the top of the vessel to allow the oil or spirit to
be introduced. It will be seen that if the vessel is charged with suitable oil or
spirit and the pump set to work, it will be filled with a gaseous compressed air.
An outlet pipe is provide in any suitable part of the vessel, and it is fitted
immediately inside the vessel with a non-return valve and immediately outside
it with a cock. To the end of the cock an india-rubber tube of any desired length
is fixed; to the other end of this rubber tube is fixed the manipulating nozzle,
which consists of a tube of about inch diameter bent in the form of an elbow,
from the top of this pipe another pipe of about & inch diameter is lead, and passing
through the top of the other pipe just at the bend, is carried inside the large pipe
to within a short distance of its end, which therefore presents the appearance of
an injector being one small pipe within a large one. Both these pipes are pro-
vided somewhere in their length with cocks placed so as to be convenient for
manipulation.

page_text: To set the apparatus to work the reservoir is charged with air, and after the
cock on the outlet pipe, and also the cock on the large pipe at the end of the nozzle
are opened, a light is applied to the nozzle when a flame will appear which may
be intensified to any degree by opening the cock of the small pipe at the nozzle so
as to let the compressed air at a greater pressure play on the flame.
It will be understood that the pressure, must be kept up in the reservoir by
constantly keeping the pump at work which may be effected by either hand or
foot, or suitable mechanism may be employed to impart motion to it from a
revolving shaft.
་
Several manipulating nozzles may be feed from one vessel and pump.
My apparatus may be used for many other purposes where an intense flame is
necessary, other than soldering; for instance it may be used for lead burning, in
which case the manipulating nozzle is made of smaller dimensions the larger pipe
is made perpendicular and the small blow pipe is brought to the edge of it, the
compressed air forcing a very fine flame which is hot enough to burn lead.
In order that my invention may be fully understood I will more particularly
describe it with the aid of the accompanying drawings on which similar parts are
marked with like letters of reference.
Referring to the accompanying drawings Fig 1 Sheet No 1 is an elevation of
the air tight reservoir and pump of my apparatus. Fig 2 Sheet No 1 is a sectional
elevation of the same and Fig 3 Sheet No 1 is a plan of the same with the covers
removed. Fig 4. Sheet No 2 is an elevation of the manipulating nozzle of my
apparatus and Fig 5 Sheet No 2 is a plan of the same.
A designates the air tight vessel constructed of any suitable material and of any
desired size, B the piston air pump constructed with a piston b fixed to a piston
rod 6 passing through a suitable stuffing box on the cap of the pump and having
a handle C attached to it outside the vessel A, so that it may be manipulated by
the user.
The pump has two valves e. e. in the auction pipe E and two valves f. f.
in the delivery pipo F. the pipes E and F having ports or openings into each end
of the pump barrel, so that the pump is a continuous acting one, charging and
delivering during each stroke. The suction pipe E communicates with the outside
of the vessel. The delivery pipe F is contained entirely within the vessel which
acts as reservoir for the compressed air, the pipe being coiled on the bottom of
the vessel and perforated with numerous small holes. On the top of this coil is
placed a quantity of cotton wool or waste, or other absorbent material (not shown
in the drawings for sake of clearness,) to take up and absorb the oil or spirit with
which the vessel is charged, so that none of the liquid is loose, thereby avoiding
the liability of it leaking. A suitable trapped opening or valve G is made on the
top of the vessel to allow the oil or spirit to be introduced. An outlet pipe H is
fixed in the side of the vessel with a non-return valve h. and on the outside with
a cock J to the nozzle of which is fitted by a running joint, a small piece of pipe j.
on to which is fixed an india-rubber tube of any length. At the other end of the
tube is fixed by a similar running joint the manipulating nozzle which consists of
a small chamber K out of one end of which is a short pipe L carrying a running
joint and small length of pipe 7. on to which the other end of the india-rubber tube
is fixed. Out of the other end of the chamber K are run two tubes M and N,
the former about of an inch in diameter, and the latter about of an inch in
diameter. The pipe M is bent in the form of an elbow, and the pipe N lies close
outside it, and passes through the top of it at the bend, and is carried inside it to
within a short distance of its end, which presents somewhat the appearance of an
injector, being a small nozzle within a large one. Both these tubes are provided
with cocks in and n conveniently placed for manipulation. If the air reservoir and
pump are, made sufficiently large several nozzles may be feed from one vessel,
in which case it would be more convenient to work the pump by steam or other
power.
To use the apparatus the vessel is charged with suitable oil or spirit, and the
pump is worked by manual or other power when the vessel becomes charged-with

page_text: a gaseous compressed air. The cock J on the outlet pipe and also the cock m,
having been opened a light is applied to the nozzle when a flame will appear, which
may be intensified to any degree and regulated by opening or partly closing
the cock n. so as to let the compressed air at a greater pressure play on the
flame.
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. An apparatus, constructed arranged and operating, as and for the purpose
hereinbefore described and shown.
Secondly. The combined pump and air reservoir constructed and arranged, as
and for the purpose hereinbefore set forth.
Thirdly. The nozzle constructed as hereinbefore described and illustrated by
Figs 4 and 5 Sheet No 2 of the accompanying drawings.
Fourthly A Boldering apparatus consisting essentially of the pump partially
enclosed within the air reservoir and manipulated by the handle outside the
reservoir, and the manipulating nozzle, all constructed arranged and operating
as hereinbefore set forth.
