COMPLETE SPECIFICATION.
An Improved Furnace or Atmospheric Burner for Using
Acetylene Gas.
I ALEXANDER STERZA, Professor. in Mantova, Italy do hereby declare the
nature of my said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
Some gases especially those, whose density is not much dissimilar from that of
the air, are not easily diffusable and in order to make them diffusable it is necessary
to break them-as the saying is-in order to mix them at the same time with
the air.
To that purpose I have found couvenient the system for which 1 intend to take
the patent.
With my system I make the gases, or force them to pass between some solid
bodies placed confusedly and so carry along with them the ambient air.
I apply this general principle to acetyline gas when it is required to have the
same diffused or mixed with the air. When the gas is wanted for heating purposes
I force the acetyline gas to pass through a series of metallic seaves disposed in
such a manner as to oblige the gas itself to pass through them.
The annexed drawing will serve to show and illustrate more clearly the following
description.
Figure 1 in the drawing represents a section made on the axis of the apparatus,
Figure 2 is the plan of the smaller base with the projection of the annular tube
of the small jets ;
Figure 3 is the metallic disc of the larger base.
The trunk of a metallic cone overturned A B C D (Figure 1) is opened at the
lower end CD and in the same the acetyline gas is introduced through the
small boles F F F (in the plan F1 F1 F1, Figure 2) of the annular tube which is
fixed near the lower base of the cone and is placed in communication with the
tube G of the said gas.
Instead of conducting the gas through the said tube the same can be conducted
by means of several single tubes or otherwise.
Another overturned cone's trunk A¹ B' C¹ D', of smaller dimensions, is placed
inside the first cone on the same axis; this internal cone is opened at the two
bases or ends and has the larger base A¹ B₁ somewhat distant from the base A. B
of the first cone's trunk.
Above the holes F F F .
made on the annular tube there is a series of wire
cloths rolled up and placed confusedly which reacts down to base A. B. of the cut
Cone.
The base A B' is closed by a thick wire net.
The base A B. is closed by a metallic disc thickly perforated near the circum-
ference Figure 3.
Above the disc is placed a metallic net surmounted by another net made of
asbestos, and above this is placed a wire cloth or sheet on which upper surface is
collected the diffused gas mixed with the air.
Instead of the asbestos cloth another wire net can be used and this according to
the purpose for which the apparatus is to be used, that is to say if it is required to
have a low flame with much heat or else a high dame is wanted just to simply lap
touch or lick the walls of the objects to be heated.

The inside cone determines a current of air which runs toward the upper part of
the furnace and so aids considerably the mixing of the air with acetyline and the
-combustion.
The inner cone can be substituted by an iron tube either straight or of serpentine
form with the object of obtaining a smaller or larger quantity of air.
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.
A furnace or any other apparatus having for object to render acetyline gas
suitable for the heating purposes; the same being formed of two vases one inside
the other and between which the acetyline gas is conducted passing through
several wire cloths and nets and asbestos cloths before being burnt and so becoming
mixed with the air, substantially as herein before set forth and illustrated.
Dated the 19th day of January 1897.
