Year: 1874

page_text: LETTERS PATENT to Henry Edward Newton, of the Office for
Patents, 66, Chancery Lane, in the County of Middlesex, Civil
Engineer, for the Invention of "IMPROVEMENTS IN GAS BURNERS."-
A communication from abroad by Alonzo Tunstall Welch, of
Vol. TT
Sealed the 4th August 1874, and dated the 24th June 1874.
PROVISIONAL SPECIFICATION left by the said Henry Edward
Newton at the Office of the Commissioners of Patents, with his
Petition, on the 24th June 1874.
I, HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN GAS BURNERS," to
be as follows:-
This Invention relates more particularly to argand gas burners in which
the burner is made with a hollow metal ring receiving at its upper
part a nearly flat ring of aluminium perforated with holes for the
escape of gas. The aluminium ring is held in place by the edge of

page_text: the metal of the hollow ring being folded over its edges.
Within the
hollow metal ring is a deflector plate that leaves an annular opening
for the passage of the gas, so that it is supplied with uniformity to the
flame.
The hollow arms for the gas to reach the burner ring are united to 5
a short sheet metal cylinder that is inserted into the open upper end
of the cylindrical body of the burner, thereby forming a chamber in
which the gas becomes heated, and this construction allows of the
burner being easily removed, cleaned, and replaced.
The lower end of the cylindrical body of the burner screws upon the 1
gas supply pipe, and the gas passes through the central hole into the
said body. Around the upper end of this hole is a seat for a valve to
regulate the quantity of gas passing to the burner.
The valve itself is made cylindrical, fitting into the cylindrical open-
ing in the body of the burner, and one or more sides of this cylinder 1
are removed to form gas passage ways, and a small radial groove at the
valve end of this cylinder serves to allow a small quantity of gas to
pass when the valve is resting on its seat, thereby preventing the light
being extinguished.
The valve cylinder has a mortice in it, into which is inserted an 2
excentric, and the stem of the excentric is inserted from outside the
body and fits tightly into the excentric; the valve cylinder, whero
the stem passes through it, is made with enlarged holes, so as to allow
the cylinder to be raised or lowered by the excentric and operate as a
valve, and a small helical spring in one of these holes, resting at one 2
end against the interior of the body and at the other end against a
shoulder in its hole, serves to produce the friction required for holding
the valve in any position to which it may be adjusted.
In order to support a chimney or a shade without casting a shadow
I make use of wire arms that are bent near their inner ends in an 3
S form, and the ends of the wires pass vertically through holes in a
flange surrounding the body, and the S bend of the wire bearing
against the outer surface of the flange retains cach arm in its proper
radial position, but allows any of the arms that may not be required for
use to be removed or replaced with great facility. The long arms serve 3
to hold a shade or globe and the short ones a glass chimney.

filed by the said Henry Edward Newton in the Great Seal Patent
Office on the 19th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of June, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Henry Edward Newton,
Her special licence that I, the said Henry Edward Newton, my execu-
tors, administrators, and assigns, or such others as I, the said
Henry Edward Newton, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN GAS BURNERS," a communi-
cation to me from abroad by Alonzo Tunstall Welch, of Brooklyn, in
the State of New York, United States of America, upon the condition
(amongst others) that I, the said Henry Edward Newton, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being made to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that
is to say):-
:-
A perforated ring of alluminum is secured at its edges within a
hollow burner ring within which is a deflector to equalize the flow of
gas.

page_text: A cylinder at the lower end of the arms to the argand ring is
removable with the burner from the body.
A cylindrical valve within the body is operated by an eccentric, and
a friction spring is provided to hold the valve when adjusted.
The wire arms holding the chimney or shade are made with an
S shaped spring bend and inserted in holes in a flange around the body.
In the Drawing. Fig. 1 is a vertical section of the burner complete.

A cylinder at the lower end of the arms to the argand ring is
removable with the burner from the body.
A cylindrical valve within the body is operated by an eccentric, and
a friction spring is provided to hold the valve when adjusted.
The wire arms holding the chimney or shade are made with an
S shaped spring bend and inserted in holes in a flange around the body.
In the Drawing, Fig. 1 is a vertical section of the burner complete.
Fig. 2 is a section, in larger size, of the burner ring detached.
Fig. 3 is a plan of the body of the burner.
Fig. 4 is a plan of the burner ring.
Fig. 5 is a plan and section of the annular deflector plate.
Fig. 6 is a section, and Fig. 7 is a perspective view of the cylindrical
valve, stem, and eccentric in larger size.
This Invention relates more particularly to argand gas burners, and
the burner is made with a hollow metal ring a receiving at its upper
part a nearly flat ring of alluminum perforated with holes for the
escape of gas. The alluminum ring is made with recessed or flanged
edges, so as to be held in place by the edges of the metal of the hollow
ring a being folded over its edges; this construction prevents the gas
from coming into contact with the turned over edges of the ring a.
Within the hollow metal ring is a deflector plate c that leaves an
annular opening d for the passage of the gas, so that it is supplied with
uniformity to the flame.
The hollow arms e for the gas to reach the burner ring bare united
to a short metal cylinder / that is inserted into the open upper end of
the cylindrical body of the burner, thereby forming a chamber in
which the gas becomes heated; and this construction allows of the
burner being easily removed, cleaned, and replaced.
The lower end of the cylindrical body % of the burner screws upon
the gas supply pipe and the gas passes through the central hole o
into the said body. Around the upper end of this hole is a seat for a
valve n to regulate the quantity of gas passing to the burner.
The valve itself is made cylindrical, fitting into the cylindrical open-
ing in the body k of the burner, and one or more sides of this cylinder

page_text: are removed to form gas passage ways, and a small radial groove 2 at
the valve end of the cylinder serves to allow a small quantity of gas
to pass when the valve is resting on its seat, thereby preventing the
light being extinguished.
The valve cylinder n has a mortice in it, into which is inserted an
eccentric i, and the stem of the eccentric is inserted from outside the
body and fits tightly into the eccentric; the valve cylinder n, where
the stem passes through it, is made with enlarged holes, so as to allow
the cylinder to be raised or lowered by the eccentric and operated as a
valve; and a small helical spring s in one of these holes, resting at one
end against the interior of the body k and at the other end against a
shoulder in its hole, serves to produce the friction required for holding
the valve in any position to which it may be adjusted.
In order to support a chimney or a shade without casting a shadow,
wire arms t, u, are made use of that are bent near their inner ends in
an S form, and the ends of the wires pass vertically through holes in a
flange 4 surrounding the body k, and the S bend of the wire bearing
against the outer surface of the flange 4 retains such arm in its proper
radial position, and allows any of the arms that may not be required for
use to be removed or replaced with great facility. The long arms serve
to hold a shade or globe, and the short ones a glass chimney.
