CHARLES HENRY GREEN residing at No. 118 West 123rd Street in the City of
New York in the State of New York, United States of America Merchant do hereby
declare the nature of my invention for GAS BURNERS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
My improvement relates to gas burners of the kind which are termed annular or
Argand gas burners, and it consists in a burner tip composed of two cylindrical shells
of metal connected at the bottom by an intermediate ring shaped piece of metal, and
at the top by a perforated piece of metal. A pipe is used which is made in two
sections, the lower of which has a socket whereby it may be screwed onto the nipple
of a gas fixture, and the upper of which has a socket whereby it may be screwed onto
the lower section. Pipes connect this pipe with the annular burner tip. By screwing
the upper section of said pipe more or less down upon the lower section, the flow of
gas to the burner, may be varied. A handle may be employed to rotate the upper
section. In the burner tip there is arranged between the two shells, a perforated
plate. Gas enters below this plate and passes through the perforations, by which it is
broken пр into small jets before reaching the point of ignition. The perforations or
holes in the top of the burner tip are arranged in two circular rows; those of one row
being opposite the spaces between those of the other row. From the top of the upper
section of the pipe referred to, a rod extends upwardly and supports a button or
spreader.
In the space surrounded by the inner wall of the burner tip, perforated air dis-
tributors are arranged. Extending from the outer shell of the air distributor is a
perforated air distributor upon which is mounted a deflector and a chimney gallery.
In the accompanying drawing Figure 1 is a vertical section of a gas burner
embodying my improvement. Figure 2 is a horizontal section of the same taken at
the linex Figure 1. Figure 3 is a top view of the burner tip. Similar letters of
reference designate corresponding parts in all the figures.

page_text: A designates the burner tip. It consists of two cylindric shells of brass or other
suitable metal, a¹ a connected together at the bottom by an intermediate ring shaped
piece of metal a' and at the top by a smaller piece of metal a' having numerous
perforations.
B'B' designate a pipe made in two sections, the lower B2 of which has an internally!
screw-threaded socket so that it may be secured to the nipple of a gas fixture and
receive gas therefrom. Above this socket is a gas duct 6 extending to the upper
extremity of the section B³. The upper portion of this section B2 is externally of
smaller diameter than the lower portion and is screw threaded externally. The upper
section B' of the B2 B¹ has in the lower portion a cavity which is screw threaded
internally so as to fit the external thread of the upper portion of the section B². From
this section B' pipes 6 extend. Any suitable number of these pipes 62 may be used
although three will suffice. They communicate with the cavity in the section B¹ and
extend to the inner shell a¹ of the gas burner tip A. Gas may flow from the gas
fixture through the pipe B2 B¹ and the pipes 62 to the gas burner tip A.
The section B¹ of the pipe B2 B¹ is imperforate above the section B³, consequently
when the section B¹ is screwed downwardly as far as it can go, it will approach the
more nearly to the upper end of the section B* as to permit of the passage of very
little gas to the burner tip, and when moved to its fullest extent in the opposite direc-
tion, it will permit of the free flow of gas to the burner tip. A pin in the section B²
acting in conjunction with a slot or groove in the section B¹ limits the rotation of the
latter. The section B' may be rotated by rotating the burner tip through the agency
of a handle C extending therefrom.
In the burner tip there is arranged between the two shells a¹ a², a perforated
plate a. The gas which enters the burner tip is received below this perforated plate aº.
The latter causes it to circulate around the burner tip so that it will pass into the
upper portion of the burner tip uniformly around the same. Without this perforated
plate a the gas would be apt to pass up through the burner tip in streams corre
sponding in position and number to the pipes 63 and although before reaching the top
of the burner tip this stream would have become distributed circumferentially around
the burner tip so as to meet and escape at all portions of the top of the burner tip, yet
they would have a tendency to maintain their separate identity and pass out in greater
volumes at portions of the top of the burner located above the pipes 6* causing the
flame to be ragged or forked. As the plate a³ obviates this and causes the gas to
ascend more uniformly throughout the burner tip to the top of the latter, the flame
will be more uniform.
The perforations or holes in the top of the burner tip are arranged in two circular
rows; those of one row being opposite the spaces between those of the other row. I
have found that this arrangement conduces to uniformity of the flame.
From the top of the upper section B¹ of the pipe B¹ a rod C¹ extends upwardly and
at the upper end sustains a button or spreader D.
In the space surrounded by the inner shell a¹ of the burner tip, perforated air dis-
tributors EE are arranged. Air ascending through this space is divided up into
small jets and reaching the button or spreader is deflected outwardly against the
flame.
Extending from the outer shell a³ of the burner tip is a perforated air distributor F
and upon which are mounted a deflector Gand a chimney gallery H. This deflector G
directs towards the flame, the air which passes up through the air distributor F.
Preferably an air distributor I will be arranged between the outer shell a³ of the
burner tip and the deflector G.
The chimney gallery is provided with resilient fingers which serve to hold the
chimney in place and are bent outwardly so as to be adapted to support the holder for
a globe or shade.
"While chimneys of various shapes may be used with this burner, I prefer to use a
chimney J having a cylindric base portion and globular portion arranged above the
same and a tubular upper portion.

page_text: Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. The combination with an annular gas burner of a button or spreader for direct-
ing air upwardly against a flame, substantially as specified.
2. The combination with an annular gas burner of an outer deflector for directing
air inwardly against the flame, substantially as specified.
3. The combination with an annular gas burner of air distributors for dividing up
the air passing to a flame emanating therefrom, substantially as specified.
4. An annular gas burner having in its top a plurality of rows of perforations or
holes arranged so that the holes or perforations of one row will be opposite the spaces
between those of another row, substantially as specified.
5. The combination with an annular gas burner tip of a number of pipes for con-
ducting gas thereto, and a perforated ring or plate arranged within said burner tip
between the shells and below the top thereof for distributing the gas uniformly around
the burner tip, substantially as specified.
6. An annular burner having a feeding pipe composed of two sections connected
together by screw threads, the upper being connected to the burner tip by inter-
mediate pipes and being capable of rotation upon the lower so as to control the flow of
gas, substantially as specified.
