Year: 1859

page_text: LETTERS PATENT to Samuel Wright, of Sudbury, in the County of Suffolk,
Gas Engineer, for the Invention of "AN IMPROVED GAS GOVERNER OR
REGULATOR."
Sealed the 27th October 1859, and dated the 6th May 1859.
10 SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Wright in the Great Seal Patent Office on the
5th November 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
WRIGHT, of Sudbury, in the County of Suffolk, Gas Engineer, send greeting..

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of May, 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 Samuel Wright, Her special licence that I, the said Samuel Wright,
my executors, administrators, and assigns, or such others as I, the said
Samuel Wright, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 IM-
PROVED GAS GOVERNOR OR REGULATOR," upon the condition (amongst others)
that I, the said Samuel Wright, 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 Samuel Wright, 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, reference being had to the Sheet of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
I govern or regulate the pressure of gas by passing and diffusing it through
a woven texture of linen, cotton, silk, hair, or it may be a metal fabric into a
chamber or chambers to which the burner is attached, the pressure of the gas
at the jet of the burner being thereby governed and regulated as required.
This woven fabric of fibrous or other material I stretch in a small chamber, to
which the gas is admitted in its passage to the burner in the form of a
diaphragm, through which the gas must pass before escaping at the burner.
Instead of one diaphragm of woven fabric, two or more like diaphragms may
be interposited if required

page_text: together, the nipple or burner being screwed into a, and the supply tube into
part b. I form a small recess in the upper part of b, and fit therein a light
ring c, by which the diaphragm d of woven material is fixed. To introduce it
the disc of woven material is laid on the top of b, and the ring c then forced
down into its recess, carrying with it the woven material, and so straining
tight.
The detail views show the ring and diaphragm of woven material separately,
with the woven material; in this position, in the passage of gas to a burner, the
gas is constrained to pass through the meshes of the material, and be so
diffused and equalized in its pressure, causing the flame to burn steadily and
without flickering, thereby effecting great saving of gas, and producing a better
light than can be produced without such governing or regulating, which it
effects in a much higher degree than can be secured by other regulators. This
regulating diaphragm can be readily cleaned by washing, or a new material
may be introduced if required.
Having described the nature of my Invention, and the manner of performing
the same, I declare that what I claim as my Invention to be protected by the
herein-before in part recited Letters Pattent is, passing gas through a diaphragm
or piece or pieces of woven material, as, and for the purposes herein-before
described.
In witness whereof, I, the said Samuel Wright, have hereunto set my
hand and seal, this Third day of November, in the year of our Lord
One thousand eight hundred and fifty-nine.
SAMUEL WRIGHT. (L.S.)
