Year: 1867

page_text: LETTERS PATENT to Elliott Perry Gleason, of the City and County of
New York, in the State of New York. and United States of America,
Gentleman, for the Invention of "IMPROVEMENTS IN CYLINDRICAL OR
'ARGAND' GAS BURNERS."
Sealed the 17th December 1867, and dated the 24th June 1867.
PROVISIONAL SPECIFICATION left by the said Elliott Perry Gleason
at the Office of the Commissioners of Patents, with his Petition, on
the 24th June 1867.
I, ELLIOTT 'PERRY GLEASON, of the City and 'County of New York, in the
State of New York, and United States of America, Gentleman, do hereby
declare the nature of the said 'Invention of "IMPROVEMENTS IN CYLINDRICAL OR
ARGAND GAS, BURNERS," to be as follows:-
In the usual forms of "argand",gas burners the gas passes directly from
the inlet opening of the supply pipe.through the burner to its flame apertures
with an unobstructed flow; the gas thus reaches the flame under great
pressure, which is manifest ordinarily by a peculiar unpleasant hissing or
singing sound in the burner.
This Invention relates to certain novel :devices for obviating these defects,
consisting, firstly, in the use of an obstructing or deflecting point. or surface
placed within the burner immediately over or in front of the inlet opening
through which gas enters, the, burner;, and, secondly, in the multiplication of
the apertures in the top of the cylindrical burner which feed the flame by

page_text: forming a second series of such apertures concentrically or otherwise within or
without the flame apertures as ordinarily arranged. Screws may be used
as deflectors by inserting them through the casing of the lower portion of the
burner in a right line with the inlet opening supplying gas thereto, so that
the point or end of the screw shall reach the said opening to cover and, if
desired, close the same. By turning the screw its point is made to approach
or recede from the opening, increasing or diminishing thereby the flow of gas,
while the gas impinging against the end of the screw is thereby in a measure
retarded in its flow and is deflected and distributed within a suitable space in

of using a simple screw whose end presents but a slight deflecting surface it
is often preferable to place an extended plate or disc over the inlet aperture
against which the current of gas shall impinge. Such a disc or plate may be
made to approach or recede from the inlet aperture by means of a screw or
other mechanical device, and will serve more effectually than a simple screw
point to arrest and distribute the gas and to produce an even flow thereof
to the burning apertures by diminishing its pressure. By duplicating or
multiplying the apertures in the top of the burner through which the gas is
supplied to the flame a more perfect combustion of the gas is obtained,
creating consequently a softer and more brilliant light than in the ordinary
burners.

Letters Patent.
NOW KNOW YE, that I, the said. Elliott Perry Gleason, 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:--
or
The nature of my Invention relates to improvements in the construction of
argand gas burners for the purpose of preventing the hissing singing noise
usually attendant upon the passage of gas through the same, and also to
regulate the supply of gas thereto, and provide for its more thorough consump-
tion therein; and said Invention consists in placing an adjustable deflecting
point or surface immediately over or in front of the inlet, aperture through,
which gas is supplied to the burner, and in duplicating its jet or flame.
openings.
In the accompanying Drawings, forming a part of this Specification.
Figure 1 is an elevation, and Figure 2 a vertical diametric section of an
argand burner in which my inprovements are introduced, the deflection of the
current of gas being obtained by the adaptation of a screw placed over the:
inlet aperture; Figure 3 is an elevation, and Figure 4 a section of an argand,
burner, illustrating a modification of the screw arrangement shown in Figures.
1 and 2; Figure 5 is a top view of the improved burner, illustrating the
duplication of jet openings; Figures 6 and 8 are respectively elevations,, and,
7 and 9 vertical diametric sections of burners, illustrating other modifications.
of my improvements wherein plates or disks presenting exten ed surfaces are.
employed for deflecting and regulating the flow of gas to the burner..
My improved cylindrical burners may each be constructed in two sections.
or divisions. A, in the accompanying Drawings, representing..the lower, or
bottom, and B'the upper or top divison thereof. The lower section, A is pro-
vided with the inlet i for introducing the gas to the burner, arranged as fully
illustrated in the sectional Figures of the Drawings. The upper, section; B.
consists of a burner (formed as usual of an inner and an outer tube or cylinder:

page_text: enclosing between them an annular space 6), which is combined by suitable
hollow arms a; a, or otherwise with a hollow cap C below, made to screw
over and upon the top of the lower section A. This cap C is so formed as
that when it is screwed down in place upon the lower section of the burner a
vacant space or chamber D shall be left in the cap over the inlet opening in
said lower section; this distributing chamber D over the inlet i is connected
with the annular space 6 in the upper section by means of apertures pierced
from the one to the other through the arms a, a, connecting the upper cylindrical
burner with the cap C. Where the inlet opening i in the lower section A is
pierced centrally I insert a screw E through a suitable screw aperture formed
centrally in the top of the cap C, as shown in Figure 2, so that its point (which is
properly flattened for the purpose) shall close down immediately over and upon
said inlet. The upper end of the screw E may be fitted with a projecting.arm
or lever e, by which to be readily turned when desired. The annular space 6 of
the burner is closed; as is usual in the construction of cylindrical burners, but
instead of having but one series of jet openings s, s, Figure 5, pierced through
the top thereof, as in the ordinary forms of such burners, I make a second
series of openings s', 's', in the same, thus supplying two currents of gas to the
flame, increasing thereby the brilliancy of the light and obtaining a more
thorough consumption of the gas supplied and a low pressure thereof.
more simple arrangement of the regulating screw is obtained by forming the
inlet aperture in the lower section laterally, and inserting the screw E¹
through the side of the section opposite the same, as illustrated. in. Figures 3
and 4 of the Drawings.
A
In the modifications of my improvement, illustrated in Figures 6 and 7,
8 and 9, the distributing chamber D in the cap C is somewhat enlarged or
widened over the inlet opening i in the lower section A, and a flat plate or
disk G is fitted therein to drop down over and upon the said opening, at which
point it is supported by and upon slight projections from the side of the
chamber; this disk G may be elevated by means of a regulating screw F
operating from without obliquely through the lower section against the same,
as shown in Figures 6 and 7, or by means of a spindle K, screwing down
centrally through the top of the cap C, and having its lower end attached
loosely to the disk, said spindle being operated by means of an arm or lever k,
as illustrated in Figures 8 and 9.
In operation, the gas flowing in through the inlet aperture i in the lower
section A of my burner, impinges against the end of the screw E, or the face
of the disk G, placed over said aperture (which in either case deadens or
prevents the hissing whistling sound otherwise occasioned by the pressure of

page_text: the gas forced through the small inlet opening i), and being deflected thereby
is distributed throughout the chamber D in the cap C, whence it passes with
an even flow into the annular space b.of the burner, to be thence supplied to
the flame through the double openings s, s¹, at the top, illustrated in Figure 5.
By causing the screw E to approach or recede from the inlet opening, or by
elevating or depressing the disk G placed over said opening, the pressure of
the gas in the burner and the quantity to be burned therein can be perfectly
adjusted, the disk G or screw E being elevated to increase, or depressed to
diminish the pressure and supply.
I contemplate applying my improvements to any form or variety of cylindrical
burners.
And having thus fully described my Invention, and illustrated some of the
best modes of using and applying the same, I claim as new in the construction
of a cylindrical or "argand" gas burner,-
First, the use or employment of a regulating screw in combination with the
inlet or supply opening of the burner, in the manner and for the purpose
herein-before specified.
Second, the combination of an adjustable regulating plate or disk with the
inlet or gas supply opening of the burner.
And, third, providing an argand gas burner with a double series of
concentric jet openings to supply the flame, substantially in the manner herein
set forth.
In witness whereof, I, the said Elliott Perry Gleason, have hereunto set
my hand and seal, this Twentieth day of November, A.D. 1867.
