REGULATING GAS BURNERS, WHICH HE CALLS THE UNIVERSAL GAS BURNER'S REGULATOR
Year: 1859

page_text: LETTERS PATENT to George Kennedy Geyelin, Civil Engineer, of London',
for the Invention of "REGULATING GAS BURNERS, WHICH HE CALLS THE
UNIVERSAL GAS BURNER'S REGULATOR."
Sealed the 10th June 1859, and dated the 7th January 1859.
PROVISIONAL SPECIFICATION left by the said George Kennedy Geyelin
at the Office of the Commissioners of Patents, with his Petition, on the
7th January 1859.
I, GEORGE KENNEDY GEYELIN, Civil Engineer, of London, do hereby declare
5 the nature of the said Invention for "REGULATING GAS BURNERS, WHICH I CALL
THE UNIVERSAL GAS BURNER'S REGULATOR," to be as follows:-
The difference between the ordinary gas regulator with valve and this
consists,-1. That I interpose between the valve and the burner a perforated
chamber, the. holes of which will not pass more gas than is necessary for
consumption under low pressure to the burner, by which means the flame of
Argand, Dumas, and all other burners remain invariable under any variation
of pressure.
2. To prevent the almost total closing of the valve by a very
great pressure; the valve can also be perforated.

by the said George Kennedy Geyelin in the Great Seal Patent Office on

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
KENNEDY GEYELIN, Civil Engineer, of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of January, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Kennedy Geyelin, Her special licence that I, the said George
Kennedy Geyelin, my executors, administrators, and assigns, or such others
as I, the said George Kennedy Geyelin, 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 "REGULATING GAS BURNERS, WHICH I CALL THE UNIVERSAL GAS
BURNER'S REGULATOR," upon the condition (amongst others) that I, the said
George Kennedy Geyelin, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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 George Kennedy Geyelin, 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 and accompanying Drawing (that is to say):-
The difference between the ordinary gas regulators with valves and this
cousists, that I interpose between the valve and the burner an inner perforated
chamber, the hole of which will not pass more gas under low pressure than is
necessary for the consumption of the various kind of burners. To prevent
the almost total stoppage of the supply of gas under very high pressure
when the valve is closed, the valve can be perforated, or a hole made in
the outer case.

page_text: DESCRIPTION OF THE DRAWING.
Full-size Section.
A is a spherical valve, which, when lifted by the dia-
phragm over chamber B, closes against the cone ; this
construction allows the regulator to act horizontally;
chamber B is perforated, the number or size of holes
varying according to the description of burners used; thus
Argand burners of thirty holes require more or larger holes
than fish-tail or bat-wing burners; but should the burners
be changed at any time, it is easy to stop some of the holes
up with white lead, or enlarge the holes with a broach
according to requirement. The holes ought to be only [The filed Drawing is not
sufficiently numerous or large to admit sufficient gas to the burner under low
pressure; the moment the pressure increases, the gas lifts the diaphragm of
oiled silk over chamber B, which closes partially the valve; but to prevent
the almost total stoppage of the supply of gas under very high pressure when
the valve is closed, it is perforated with a hole sufficiently large to supply the
burner. From chamber B the gas passes into the outer chamber C, where it
expands previous to reaching the burners; under the diaphragm a bridge is
shewn, which prevents the valve from sinking; but I use also in some cases
a support from below by means of a cone.
colored.]
Having thus fully described the nature and object of my Invention, what I
claim therein as new and desire to secure by Letters Patent is, regulating the
supply of gas by means of the inner perforated chamber and the perforated
valve, also the general construction of the regulator as described.
In witness whereof, I, the said George Kennedy Geyelin, have hereunto
set my hand and seal, this Seventh day of July, in the year of our
Lord One thousand eight hundred and fifty-nine.
