GAS BURNERS." A communication from abroad by Edward Ferguson,
No. 10, Rue Mogador, Paris, in the Empire of France.
Sealed the 13th December 1859, and dated the 16th June 1859.
PROVISIONAL SPECIFICATION left by the said Jozé Luis at the Office
of the Commissioners of Patents, with his Petition, on the 16th
June 1859.
I, JOZÉ LUIS, of the British and Foreign Office for Patents, No. 1³,
Welbeck Street, Cavendish Square, London, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention for
"AN APPARATUS FOR REGULATING INDIVIDUALLY THE PRESSURE, EXPENDITURE, AND.
LIGHT IN GAS BURNERS," a communication to me from abroad by Edward.
Ferguson, No. 10, Rue Mogador, Paris, in the Empire of France, to be as
follows:-
By means of this apparatus or regulator the maximum of light is obtained
in all parts of a building, &c., notwithstanding the different degrees which it;
is desired to obtain. Its application is very simple; it can be adapted to any
pipe, and is very cheap. This result is obtained by the introduction of an
obstructor in the key of the cock of each gas burner.

The obstructor is represented, Fig. 1, as applied to an ordinary pipe; the
key a of the cock has a screw-cut hole bored in it, and in this hole a screw b,
One end of the screw 6 is rounded, and
about of an inch long is inserted.
the other grooved to admit of its being advanced or withdrawn by means of a
turnscrew, Fig. 3 the orifice by which it is introduced is lastly closed by a
round-headed screw c.
Admitting that the pressure be maintained the same at its entrance in the
building, &c., either by a cock or regulator, and knowing the nature of the
burners to be employed, together with the pressure necessary to arrive at a
given expenditure for obtaining the maximum of light, the apparatus is
regulated as follows:-1st., the screw plug c, Fig. 1, is removed by means of
the key P, Fig. 3; 2nd., the manometer n, Fig. 2, is substituted for the
burner m, Fig. 4, which is replaced at o, Fig. 2; 3rd, the burner is lighted;
4th, the screw b, Fig. 1, is advanced or withdrawn by means of the turnscrews,
Fig. 3, till the manometer indicates the desired pressure; 5th, the screw
plug c is then replaced, and the operation is terminated. This arrangement,
as shown by the Fig. 5, can be also employed in gauge cocks for water, &c.,
for preserving an equal flow.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jozé Luis in the Great Seal Patent Office on the 15th
December 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JozÉ
Luis, of the British and Foreign Office for Patents, No. 1", Welbeck Street,
Cavendish Square, London, in the County of Middlesex, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of June, 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 Jozé Luis, Her special licence that I, the said Jozé Luis,
my executors, administrators, and assigns, or such others as I, the said
Jozé Luis, 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 "AN APPARATUS

page_text: FOB REGULATING INDIVIDUALLY THE PRESSURE, EXPENDITURE, AND LIGHT IN GAS
BURNERS," a communication from abroad by Edward Ferguson, of No. 10,
Rue Mogador, Paris, in the Empire of France, upon the condition (amongst
others) that I, the said Jozé Luis, 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 Jozé Luis, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, and accompanying Drawings, that is to say: -
The object of the present Invention is an apparatus or regulator, by means
of which the maximum of light is obtained in all parts of a building, notwith-
standing the different degrees which it is desired to obtain. Its application is
simple; it can be adapted to any pipe, and is very cheap. This result is
obtained by the introduction of an obstructor or regulator passing through the
key of the cock of each gas burner.
Fig. 1 represents the obstructor b as applied to an ordinary cock: the key a
of the cock has a hole screw-cut in it, and in this hole a screw b, acting as
obstructor about of an inch in length, rounded at one extremity, and grooved
at the other to admit of its being advanced or withdrawn by means of a turn-
screw s, Fig. 4 is introduced; the orifice by which it enters is lastly closed by
a round-headed screw c. Fig. 2 represents a cock, in which the screw b,
Fig. 1, is replaced by a little key d, held in its position by a screw m; Fig. 3
represents a manometer, by aid of which the pressure at each burner may be
regulated; Fig. 4 represents the key and turnscrew.
Admitting that the pressure be maintained the same at its entrance in the
building either by a cock or regulator, and knowing the nature of the burners
to be employed, together with the pressure necessary to arrive at a given
expenditure for obtaining the maximum of light, this apparatus is regulated
as follows:-The screw plug c, Fig. 1, is removed by means of the key P,
Fig. 4; the manometer n, Fig. 2, is substituted for the burner m, Fig. 5,
which is replaced at o, Fig. 2, and the gas is lighted. The screw or
obstructor b, Fig. 1, is then advanced or withdrawn by means of the turnscrew
Fig. 4, till the manometer indicates the desired pressure.
Having thus described my Invention, and the manner in which the same is
or may be carried into effect, I wish it to be distinctly understood that I do

page_text: not confine myself to the precise details, as they may be varied and modified
without departing from the principle; what I claim, and desire to secure by
Letters Patent, is the arrangement as above described and represented in the
annexed Drawings, and of which the screw bor its equivalent acting as
obstructor, & the aperture a arranged in the key of the cock to receive the
obstructor, are the chief features.
In witness whereof, I, the said Jozé Luis, have hereunto set my hand
and seal, this 15th day of December, in the year of our Lord One
thousand eight hundred and fifty-nine.
