This invention relates to certain improvements in forges for the purpose or
object of using hydrocarbon and volatile oil vapours or any of them for blowpipe
purposes, and in order that the same may be readily understood reference is
made in the following description to a sheet of drawings illustrative of the
invention
B is a sheet iron or other metal cylinder in which is placed a cylindrical leather
bellows actuated by means of pedal C. To the cylinder is attached a tube D' by
which the bellows blast is conducted, said blast on its passage to the discharge
nozzle D being governed by the tap or cock G (when the handle or key g, is placed
in a vertical position the discharge is open). E is the forge hearth or pan.
Thus a portable forge is provided which may be worked with coals without
having applied thereto the rest part of my Invention.
The portion of this Invention which has for object the use of hydrocarbon or
inflamable vapours is as follows:-

On turning the key g of the tap G, to the horizontal position the direction of
the blast is changed and directed to the metal ball F by the tube f, which latter is
brazed to and in communication with the interior of the tap G. The ball F, serves
as a reservoir of air which will escape by the tubes a b c d in different directions.
From the underside of the ball F, the said four tubes a b c d are carried down to
a copper cylinder H, surmounted by a bell cover h, terminating in a hollow ball h¹
fitted with a nipple on to which is screwed a conduit pipe K. Inside the hollow
ball is a loose ball k acting as a valve.
Inside the cylinder H, wherein is placed the liquid hydrocarbons or volatile oils,
are carried the continuations of the pipes a b c d whereof the two first pass

valves D. The two other pipes c d are bent and are carried out and joined at I.
The cylindrical reservoir H is fitted with two horizontal metal division plates p,
between which there is disposed a filling of sponge. The screw capped opening o
serves for the introduction of the liquid and the opening o¹ for drawing off or
emptying the contents. The bolt e is to fix the apparatus at the foot.
By the side of the opening o in the mouth of the tube S which is closed at the
bottom and descends nearly to the bottom of the cylinder and is destined to
receive a lug T of red copper, which is secured to the forge by the chain V, fitted
with the disc U, which will serve to close the mouth of tube S, when the plug of
copper T is introduced.
In the top of the reservoir H, is placed a box M of oval horizontal section at the
bottom and the cover receives the mouths of the two tubes ab were they are
securely fastened.
In the interior of the bell cover h is a flap valve P faced with a disc of felt.

rivetted to the bottom of the forge E, furnished with perforation at that point and
tube X, is fitted with the tap y.
Two flexible tubes K I, connect the forge apparatus with a blow pipe nozzle R,
one of the branches whereof is furnished with a small india rubber tube g.
When the pedal C is operated and the handle g of the tap G is in a horizontal
position, the air will be forced into the ball F and thence down the pipes a b
through the box M and the valves D into the cylinder H where bubbling in the
liquid contained by the said cylinder it will carry away the gaseous vapours from
this liquid in passing through the sponges; it will then pass into the india rubber
pipe K, through the opening k and finally will pass out at the nozzle of the blow
pipe.
At the same time that this production of gas takes place air from the ball F
descends by the pipes c d and arrives at the nozzle of the blow pipe by passing
through the india rubber tube I¹.
The pipe X with its tap y open is for the purpose of allowing the superabundant
supply of air coming from the bellows to be directed to the coke fire contained in
the pan E.
The piece of copper T when placed with the coke in the pan E will be heated
to red heat during the work, this piece is then passed into the tube S in order to
heat the liquid and thus greater quantity of gas will be given off.
The valves P and K are for the purpose of preventing the return to the reservoir
of the heated and possibly burning gas from the blow pipe.
The felt facing of the valve P absorbs the globules of liquid driven along with
the gas and so makes the same drier.
The valves D and the box M are for the purpose of preventing the liquid rising
with the air in the pipes a b.

PORTABLE AND STATIONARY FORGES."
"IMPROVEMENTS IN
This Invention relates to certain improvements in forges for the purpose or
object of using hydrocarbon and volatile oil vapours or any of them for blow pipe
purposes and in order that the same may be readily understood reference is
made in the following description to a sheet of drawings illustrative of the
invention.
B is a sheet iron or other metal cylinder in which is placed a cylindrical leather
bellows actuated by means of pedal C To the cylinder is attached a tube D¹ by
which the bellows blast is conducted, said blast on its passage to the discharge
nozzle D2 being governed by the tap or cock G when the handle or key g is placed
in a vertical position as shown by dotted lines the discharge is open E is the forge
hearth or pan.
Thus a portable forge is provided which may be worked with coals without
having applied thereto the rest part of my invention.
The portion of this invention which has for object the use of hydrocarbon or
inflamable vapours is as follows:-
On turning the key g of the tap G to the horizontal position the direction of the
blast is changed and directed to the metal ball F by the tube f which latter is
brazed to and in communication with the interior of the tap G.
The ball F serves as a reservoir of air which will escape by the tubes a b c d in
different directions.
From the underside of the ball F the said four tubes a b c d are carried down to
a copper cylinder H surmounted by a bell cover h terminating in a hollow ball h¹
fitted with a nipple on to which is screwed a conduit pipe K Inside the hollow
ball h' is a loose ball k acting as a valve.
Inside the cylinder H wherein is placed the liquids hydro-carbons or volatile
oils; are carried the continuations of the pipes a b c d whereof the two first pass
to the bottom of the cylindrical reservoir H and terminate with flap valves D.
The two other pipes c d are bent and are carried out and joined at I The
cylindrical reservoir H is fitted with two horizontal wire-gauze or perforated
division plates p between which there is disposed a filling of sponge. The screw
capped opening o serves for the introduction of the hydrocarbon liquid or volatile
oils and the opening o' serves for drawing off or emptying the contents.
bolt e is to fix this apparatus to the foot plate.
The
By the side of the opening o is the mouth of the tube S which is closed at the
bottom and descends nearly to the bottom of the cylinder and is destined to
receive a plug T of red copper which is secured to the forge by the chain V fitted
with the disc U, which will serve to close the mouth of tube S when the plug of
copper T is introduced.
In the top of the reservoir H is placed a box M of oval horizontal section at the
bottom the cover whereof receives the mouths of the two tubes a b were they are
securely fastened and these are continued below. In the interior of the bell
cover h is a flap valve P faced with a disc of felt. Below the tap G is brazed a
tube X connected with a sheet metal air box z rivetted to the bottom of the
forge E furnished with a perforated screen at that point and tube X is fitted with
the tap y.

page_text: Two flexible tubes K. I¹ connect the forge apparatus with a blow pipe nozzle R
one of the branches wherein is furnished with a small india rubber tube q.
When the pedal. C is operated and the handle g of the tap G is in a horizontal
position, the air will be forced into the ball F and thence down the pipes a b
through the box M and the valves D into the cylinder H where bubbling in the
liquid contained by the said cylinder it will carry away the gaseous vapours from
this liquid in passing through the sponges it will then pass into the india rubber
pipe K through the ball valve opening k and finally will pass out at the nozzle of
the blowpipe.
At the same time this production of gas takes place air from the ball F descends
by the pipes c d and arrives at the nozzle of the blow pipe by passing through the
india rubber tube I¹.
The pipe X with its tap y open is for the purpose of allowing superabundant
supply of air coming from the bellows to be directed to the coke fire contained in
the pan E.
The piece of copper T when placed with the coke in the pan E will be heated
to red heat during the work. This piece is then passed into the tube S in order
to heat the liquid contained in H and thus a greater quantity of gas will be
given off..
The valves P and k are for the purpose of preventing the return to the
reservoir H of the beated and possibly burning gas from the blow pipe.
The felt facing of the valve P absorbs the globules of liquid driven along with
the gas and so makes the same drier.
The valves D and the box M are for the purpose of preventing the liquid to rise
with the air in the pipes a b.
Having now described the nature and particulars of the said invention I
claim
First A portable bellows forge of this or that construction as regards the hearth
or framing in combination with an apparatus for using hydrocarbon and volatile
oil vapours or any of them for blow-pipe soldering purposes constructed and
operating as herein described in reference to and shown by the drawings.
Second. The use of the tap G either for the purpose of allowing the super-
abundant supply of air to be directed into the pan of the forge or for the purpose
of producing the gas or vapours by simply turning the handle g of the said tap into
a vertical or horizontal position as herein set forth.
Third. The gas or vapour apparatus consisting of the ball F pipes a b c d
