An Improved Gas Forge and Furnace.
I, HENRI BARTHELEMY BURIN of Fives-Lille, France Mechanical Engineer
do hereby declare the nature of this invention to be as follows :-
My invention has for its object an improved gas forge and furnace.
In order that my invention may be more clearly understood I refer to the annexed
drawings in which;
Fig. 1 is a cross elevation through a b Fig. 2.
Fig. 2 is a cross elevation through c d Fig. 1.
Fig. 3 is a cross section showing an apparatus with three blow-pipes.
My invention consists of a cast iron casing or frame A with an inside refractory
coating R. Through this casing passes the apparatus B B provided with two
three-way cocks C; one of these cocks C A supplies the gås, the other C B supplies
the air..
The cock C A communicates with the tubes D, the cock C B with the tubes E.
The socket C' gives admission to the air; two cocks F placed on the gas-pipes
direct this fluid through the tubes T in the tubes D and are intended to light the
apparatus.
Two stuffing boxes I are placed between the gas and the air, a small screwed
tube H unites the cocks G to the tubes E, these cocks G placed at the ends of the
tubes E are intended to dispense with the cock C B at will and also serve to regulate
the intensity of the heat. The two tubes D and the two tubes E are pierced with
holes exactly facing one another, the gas rushing from the tubes D is driven
violently by the air coming from the tube E and produces the double-blow-pipe
which makes the flame K swell with such great intensity on the piece to be
heated.
The number of holes is unlimited and they may be provided with conical beaks.
The pieces are introduced into the forge by an opening L, a stand M holds them
in their places; the escape of the heat is effected through a pipe O acting as a
chimney; two openings P are made at each end of the furnace in order to permit
the lighting of the apparatus and the heating of pieces of a certain length.
An opening Q is made opposite the entry of the pieces for the same purpose.
Those openings may be closed by any convenient stopper.
Fig. 3, shows a three blow-pipe apparatus each supplied with one or several
holes.
Two apparatuses or even three may be placed beside each other for the purpose
of heating while the smith is occupied hammering the piece.
Like the double blow-pipe it is surrounded with a refractory coating and is also
supplied by one or several special cocks. These double or triple blow-pipes are
both rendered movable by a mechanical process, that is, brought further or nearer
from each other according to the greater or less action required.
Dated this Sixth day of August 1895.

page_text: Like the double blow-pipe it is surrounded with a refractory coating, the interior
of this coating may be as represented by the dotted lines (Fig. 3) and is also supplied
by one or several special cocks. OO represent two chimneys one on each side of
the upper tube. These double or triple blow-pipes are both rendered movable by
a mechanical process, that is brought farther from or nearer to each other according
to the greater or less action required.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The general disposition of the apparatus substantially as above described and
illustrated.
2. The application and disposition of the double and triple blow-pipe acting so
powerfully substantially as above described and illustrated.
3. The interior disposition with the chimney acting with the blow-pipes to con-
centrate the heat on the pieces to be heated substantially as above described and
illustrated.
4. The disposition of the air tubes forcing the flames of the gas on the pieces
according to the degree of inclination required substantially as above described and
illustrated.
5. The disposition of all the cocks destined to render my apparatus useful and
practical substantially as above described and illustrated.
Dated this Fourth day of May 1896.
