IMPROVEMENTS IN GAS REGULATORS
Year: 1862

page_text: LETTERS PATENT to Richard Broadbent, Commission Agent, Loeds, for
the Invention of "IMPROVEMENTS IN GAS REGULATORS."
PROVISIONAL SPECIFICATION left by the said Richard Broadbent at
the Office of the Commissioners of Patents, with his Petition, on the
3rd October 1862.
I, RICHARD BROADBENT, Commission Agent, Leeds, do hereby declaro the
nature of the said Invention for "IMPROVEMENTS IN GAS REGULATORS," to be as
follows:-
My Invention consists, in the first place, in coating the surface of the
ordinary cover with an enamel or coating of glass, earthenware, or other
suitable material, for the purpose of protecting it from injury by the action
of the gas or moisture thereon. The cover is coated with the enamel both
on the inner and the outer surface, and the mode of applying it is similar to
that in ordinary use for enamelling the surfaces of metals.
And my Invention consists, in the second place, in adapting and applying
a ball and socket joint to the valve spindle and valve, for the purpose of
imparting an universal motion to the spindle in order to enable it to accommodate
itself to the curvilinear motion of the cover which works on centres at one
end, thereby obviating the inconvenience arising from the defective action
of the ordinary joint in certain positions of the spindle.

and of an Order of the Lord Chancellor, by the said Richard Broadbent
in the Great Seal Patent Office on the 30th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, J, RICHARD
BROADBENT, Commission Agent, Leeds, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of October, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Пerself, Her heirs and successors, give and grant unto
me, the said Richard Broadbent, IIer special license that I, the said Richard
Broadbent, my executors, administrators, and assigns, or such others as I,
the said Richard Broadbent, 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 Richard Broadbent, by an instrument in writing under
my hand and seal, 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
inonths next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Broadbent, 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 Drawings hereunto annexed, and to tho
letters and figures marked thereon (that is to say):-
My Invention of "Improvements in Gas Regulators" consists, in the first
place, in coating the surface of the ordinary cover with an enamel or coating
of glass, carthenware, or other suitable material, for the purpose of protecting
it from injury by the action of the gas or moisture thereon. The cover is coated
with the enamel both on the main and outer surface, and the mode of supplying
it is similar to that in ordinary use for enamelling the surfaces of metals.
And my Invention consists, in the second place, in adapting and applying a
ball and socket joint to the valve spindle and valve, for the purpose of
imparting an universal motion to the spindle in order to enable it to accom-
modate itself to the curvilinear motion of the cover which works on centres at
one end, thereby obviating the inconvenience arising from the defective action
of the ordinary joint in certain positions of the spindle.

page_text: Having thus stated the nature of the said Invention, I will proceed to
describe more particularly in what manner the same is to be performed by
reference to the accompanying Drawings, in which are represented the parts
above referred to.
Fig. 1 is a vertical section of the gas regulator, and Fig. 2 is a horizontal
section of the same in the line a, b, of Fig. 1.
A is the ordinary inlet for the gas into the regulator; B is the ordinary
valve through which the gas passes into the chamber C, which is open at top,
and is covered by the cover D, which is capable of working on centres at E at
one end, its reverse end being made to rest on mercury as shown; F is the
valve spindle, with a screw thread on its upper end, by means of which the
position of the valve is adjusted as required, the lower end of the spindle
being united to the valve by means of a ball and socket joint at G. The
ordinary outlet for the gas from the regulator is shewn at H. It will be obvious
that by means of the ball and socket connection of the lower end of the
spindle F with the valve B, the spindle F will be enabled to accommodate
itself to the curvilinear motion of the cover D on its centres at E, and in this
manner obviate the occasional inconvenience arising from the defective action
of the ordinary joint in certain positions of the spindle.
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that what I claim as of
my Invention is,―
First, the use of a cover for the regulator with an enamel or coating of
glass, earthenware, or other suitable material, on both the inner and the outer
surface of the cover, for the purpose of protecting it from the injurious action
gas or moisture.
of
And, secondly, the adaptation and application of a ball and socket joint as
a means of connecting the valve spindle with the valve, for the purpose
herein-before described.
In witness whereof, I, the said Richard Broadbent, have hereunto set
my hand and seal, the First day of April, in the year of our Lord One
thousand eight hundred and sixty-three.
Witness,
ROBERT ROBSON.
RICHARD BROADBENT. (L.S.)
