IMPROVEMENTS IN GAS REGULATORS
Year: 1863

page_text: LETTERS PATENT to John Jones, of Manchester, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN GAS REGULATORS."
Sealed the 4th December 1863, and dated the 12th June 1863.
PROVISIONAL SPECIFICATION left by the said John Jones at the
Office of the Commissioners of Patents, with his Petition, on the
12th June 1863.
I, JOHN JONES, of Manchester, in the County of Lancaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN GAS REGULATORS,"
to be as follows:-
My Invention consists, in the first place, in making the ordinary cover or
"disc," as it is termed in the trade, of galvanized iron to resist the corrosive
action of the moisture or gas.
In the second place, finding from experience that the cast-iron valve seat
in common use corrodes from the action of the moisture and frequently causes
the valve to stick, thereby preventing the proper action of the regulator, I use
a brass valve seat instead.

by the said John Jones in the Great Seal Patent Office on the 9th
December 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JONES, of Manchester, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of June, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Jones, Her special licence that I, the said John Jones, my
executors, administrators, and assigns, or such others as I, the said John
Jones, 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 REGULATORS,"
upon the condition (amongst others) that I, the said John Jones, 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 per-
formed, 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 John Jones, 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).
My improvements: in gas regulators consist, in the first place, in making
the ordinary cover or "disc," as it is termed in. the trade, of galvanized iron
to resist the corrosive action of the moisture or gas...
In the second place, finding from experience that the cast-iron valve.seat
in common use oxidizes from the action of the moisture and frequently causes
the valve to stick, thereby preventing the proper action of the regulator, I
use a valve seat of brass or any other unoxidizable metal, reference being
made to the accompanying Drawings.
Fig. 1 is a longitudinal section of my regulator shewing a brass valve
seat a, a, in section. Fig. 2 represents an end elevation of the regulator,

for letting the water out of the regulator.
Having now described the nature of my Invention, I would have it under-
stood that what I desire to be protected by the herein-before in part recited
Letters Patent is,―
First, the use of galvanized iron for gas regulator covers or discs.
Secondly, the use of brass or other unoxidizable valve seats in order to
insure the effectual working and operation of the gas regulators.
In witness whereof, I, the said John Jones, have hereunto set my hand
and seal, this Fifth day of December, in the year of our Lord One
thousand eight hundred and sixty-three.
