COMPLETE SPECIFICATION.
An Improved Burner for Acetylene Gas.
I, EMILE FRANÇOIS JEAN CLEMENT BAUWERAERTS of 8 Rue des Princes,
Brussels, in the Kingdom of Belgium, Inventor, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to a combustion apparatus or burner for acetylene gas.
In the accompanying drawing which illustrates my invention;
Figures 1, and 2 are views in elevation, and vertical section of the regulator
with the mixing chamber which constitutes the characteristic feature of my
invention.
Figure 3 is a plan view of the regulating plate.
The gas enters by the pipe into the mixing chamber j which communicates
with the external air by means of two passages & that extend obliquely from the
bottom of the mixing chamber towards the outside.
As the gas enters the said chamber, air is sucked in through the oblique
passages and an automatic mixing of the gas and air is caused thereby. The
entry of the air may be regulated by means of the plate 7 which on rotation closes
the passages k more or less.
The plate is secured to the regulator-mixing chamber by means of screws 11
and slots . Upon this regulator mixing chamber is mounted the burner
proper.
Figure 4 illustrates a three-branch burner for producing an unconfined or
unenclosed fan-shaped flame. The number of branches is optional.
Figure 5 illustrates a burner for producing an unconfined or unenclosed circular
flame. Upon the pipe or passage situated, above or over the regulator-mixing
chamber are arranged-in the form of a cross-four semi-cylindrical branches m
which are connected to a crown or ring n above which is a circumferential
chamber o having an open top or a top pierced with numerous apertures, which
constitute the regenerator for the burner. In the centre of the burner there is
arranged a stem p which widens out at its upper part. in the form of a funnel.
The acetylene gas mixed with air passes through the branches m, the ring or
crown n, and the chamber o where it is burned. The flame assumes a globular
shape by reason of the upper part of the stem p. This stem p may terminate in a
platform or plate or in any other fashion so as to impart the desired shape to the
flame. In any case however, if the head of the stem is sharp edged or projecting
it will be necessary to pierce it with apertures for the purpose of avoiding heating.
This unconfined or unenclosed burner as illustrated by Figure 5 may be employed
as a glass-enclosed burner (see Figures 6, 7 and 8) by adding to it a casing g
pierced with longitudinal apertures, and which embraces the lower part of the
burner. Upon this casing there is arranged a gallery r which carries a double
ring ss. The glass chimney or globe is adapted to fit into the outer ring, whilst
the space between the said rings is pierced with numerous apertures. The air
entering through the apertures of the casing is divided into two currents :--one,
the inner current, flowing along the stem p and along the internal surface of the
flanie, whilst the other, or outer current, is subdivided into two currents, one of
which flows between the ring and the chamber o and serves to feed the flame on
its outside, whilst the other current flows through the apertures of the double ring
and prevents the flame from licking the glass.

page_text: For simple bat's wing burners as illustrated by Figures 9 and 10 the mixing
chamber t is provided with two lateral apertures and is adapted to screw directly
under the burner which is provided at its base with a second chamber v where the
mixing is completed.
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.) A burner for acetylene gas characterized by a mixing chamber in which
there is effected a mixing of the gas supplied by a central passage or pipe, with
the air drawn or sucked in through lateral passages, and a regulator for controlling
the supply of air, the upper part being screw-threaded to receive the burners
proper substantially as hereinbefore described and illustrated in the accompanying
drawings.
(2.) A burner having three or more branches for burning acetylene gas with
an unconfined or unenclosed flame substantially as hereinbefore described and
illustrated by the accompanying drawings.
(3.) An unconfined or unenclosed burner for acetylene gas, characterized by
four semi-circular branches connected to a circular crown or ring above which
is a chamber having an open top or a top pierced with numerous apertures in
combination with a central stem whose top is widened out for the purpose of
imparting to the flame a globular or any other desired shape substantially as
herein before described and illustrated by the accompanying drawings.
(4.) In combination with the burner as claimed by Claim 3, an outer casing
pierced with longitudinal apertures for producing currents of air on the outside
and on the inside of the flame, a double ring pierced with apertures for subdividing
the outer current for the purpose of feeding the flame on the outside, and of
preventing the flame from licking the glass chimneys substantially as herein before
described and illustrated by the accompanying drawings..
(5.) A bat's wing burner for acetylene gas, characterized by a mixing chamber
forming the base of the burner and arranged above the chamber containing
the air apertures, substantially as hereinbefore described and illustrated in the
accompanying drawings.
