PROVISIONAL SPECIFICATION.
Improved Gas Burner Used in connection with Acetylene Gas, and
the like.
JAMES ST. CLAIR Legge, Artist, 38, Carlingford Road, Drumcondra, Dublin,
ARTHUR SISSON COOPER Gentleman, 42, Dawson Street, Dublin, do hereby declare
the nature of this invention to be as follows:-
In order to carry out this invention an ordinary gas burner is used or a new
one can be made of an inch from top of burner small holes are bored usually
four those holes are made one size smaller than the holes on top which the gas
passes through the idea of those four holes is to allow the air to mix with the
gas which prevent smoke.

Improved Gas Burner Used in connection with Acetylene Gas, and
the like.
We, JAMES ST. CLAIR LEGGE, of 107, Hollybank Road, formerly of 38, Carling-
ford Road, Drumcondra, in the City of Dublin, Ireland, Artist, and ARTHUR
SISSON COOPER, of 42, Dawson Street, in the City of Dublin, aforesaid, Gentle-
man, 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:-
The object of this invention is to provide a special form of acetylene burner,
or to fit existing burners with means, whereby acetylene gas can be properly
combusted, thus avoiding the production of the smoke caused by the insuffi-
cient combustion which is incident to all burners at present in use for burning
acetylene gas.
Our invention consists in providing the burner just beneath the combustion
point with a mixing chamber and apertures leading thereinto through which the
atmospheric air is drawn by the pressure of the acetylene passing through the
mixing chamber, the gas and air being thus intimately mixed in the mixing
chamber after the manner of the well known Bunsen or atmospheric gas
burner.
In the accompanying drawings Figs. 1 and 2 are respectively elevation and
vertical section of a special form of acetylene gas burner constructed in accord-
ance with our invention and Fig. 3 is a vertical section of an ordinary acetylene
Price &

page_text: gas burner to which our invention has been applied. The same parts are
lettered to correspond in the various figures.
In the form shown in Figs. 1 and 2 the burner is of the double or duplex type
having its two combustion outlets C C so arranged that when ignited the two
flames D D impinge one against the other as shown. Each combustion outlet
is supplied by a branch pipe E E leading from a main pipe F passing through
the stem or body A of the burner which is secured in the gas pipe or branch B
by screwing thereinto, as shown, or in any other suitable manner. Just beneath
each of the top plates H H¹ in which are the combustion outlets C C, is a
mixing chamber G G having side apertures g g therein through which the
atmospheric air is drawn by the pressure of the acetylene gas issuing through
the jet aperture jj¹ in the steatite or other block J J fixed in the upper end of
the branch pipe E E. The mixing chambers G G¹ are secured to their respec-
tive branch pipes E and El in any suitable manner, so that they can be renewed
when worn, preferably by screwing them thereonto as shown, but they may be
made in one with the branch pipes as will be well understood. The holes g g¹
in the sides of the mixing chamber are arranged as found suitable, preferably
they are made say about th of an inch from the top plate of the burner, are
usually four in number, and are one size smaller than the combustion outlets CC¹.
In the form shown in Fig. 3 the mixing chamber G is, as before, provided
with side apertures g and is situated just below the combustion outlet C and
between it and the jet aperture j in the block J. It will be obvious that the
mixing chamber G prowded with a combustion outlet may be formed as part
of an ordinary acetylene burner, or it may be made as a separate piece to screw
on or into or be otherwise detachably connected with the upper end of an
ordinary acetylene burner.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
-
1. An acetylene gas burner having a mixing chamber with side apertures
therein a gas jet leading into the lower part of said mixing chamber and a
combustion outlet in the top thereof so that the gas issuing through the jet
will draw atmospheric air into the mixing chamber the mixed air and gas
passing to the combustion outlet substantially as and for the purpose described.
2. The duplex form of acetylene gas burner constructed in the manner
described with reference to Figs. 1 and 2 of the accompanying drawings and
for the purpose stated.
3. For application to an ordinary acetylene burner a mixing chamber having
side apertures therein, a gas jet beneath said mixing chamber and a combustion
outlet above, for the purpose of drawing in atmospheric air through the side
aperture and intimately mixing it with the gas passing to the combustion outlet
substantially as described.
4. An acetylene gas burner constructed substantially in the manner and for
the purpose herein before described and illustrated in the accompanying drawings.
