IMPROVEMENTS IN GAS REGULATORS
Year: 1858

page_text: LETTERS PATENT to Charles Tiot Judkins, of No. 32, York Road,
Lambeth, in the County of Surrey, Engineer, for the Invention of
"IMPROVEMENTS IN GAS REGULATORS."
Sealed the 10th May 1859, and dated the 10th November 1858.
PROVISIONAL SPECIFICATION left by the said Charles Tiot Judkins at
tho Office of the Commissioners of Patents, with his Petition, on the
10th November 1858.
I, CHARLES TIOT JUDKINS, of No. 32, York Road, Lambeth, in the County
of Surrey, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN GAS. REGULATORS," to be as follows:-
In
gas regulators constructed according to the Invention of Charles Esplin,
for which Letters Patent, No. 1943, and bearing date the 27th day of
August 1855, were granted to him, or according to my Invention, for which
Letters Patent, No. 1760, and bearing date the 24th day of July 1856, were
granted to me, I fix a bar or other support across the regulator, to which I
suspend a balance lever rod at right angles therewith, and I connect one end
of such balance rod with the disc, or with the spindle of the valve, which I
place nearer the end of the regulator at which the outlet is situated than has
been hitherto done; and I have a weight or counterpoise to slide or screw on,
or otherwise connected with the other end of the balance rod, so that I can,
by moving such weight to or from the point of suspension of the balance rod,
regulate the amount of pressure at which I intend the valve in the inlet
chamber to be closed; and by such arrangement I am enabled to use a disc or
internal cover of cast iron, or other material of greater weight than has
hitherto been used in regulators.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
TIOT JUDKINS, of No. 82, York Road, Lambeth, in the County of Surrey,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of November, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Charles Tiot Judkins, Her special licence that I, the said
Charles Tiot Judkins, my executors, administrators, and assigns, or such
others as I, the said Charles Tiot Judkins, 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 Charles Tiot Judkins, 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 Charles Tiot Judkins, 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 the accompanying Sheet of Drawings, and the letters and
figures marked thereon (that is to say) :—
My improvements consist in fixing a bar or other support across gas
regulators constructed according to the Invention of Charles Esplin, for which
Letters Patent, No. 1948, and bearing date the 27th day of August 1855,
were granted to him, and across gas regulators constructed according to my
Invention, for which Letters Patent; No. 1760, and bearing date the 24th
day of July 1856, were granted to me, and I suspend to such bar or support
a balance lever rod at right angles therewith, and I connect one end of such
balance rod with the disc, or with the spindle of the valve, which I place
nearer the end of the regulator at which the outlet is situated than has been

page_text: hitherto done; and I have a weight or counterpoise to slide or screw on, or
otherwise connected with the other end of the balance rod, so that I can, by
moving such weight to or from the point of suspension of the balance rod,
regulate the amount of pressure at which I intend the valve in the inlet
chamber to be closed; and by such arrangement I am enabled to use a disc or
internal cover of cast iron, or other material of greater weight than has
hitherto been used in regulators.
Figure 1 is a vertical section, and Figure 2 is a horizontal section, of a
gas regulator with my improvements applied; the same letters refer to the
same parts in each Figure. a, a, is the bar or support; b, the balance lever
rod, which works loosely on the bar between collars or shoulders; c is the
weight or counterpoise; the lever rod, as shewn, is forked at one end, and the
ends of the fork d, d, pass under the cars e, e, which are connected with the
discf; g is the spindle of the valve h; i is the inlet chamber; the other parts
are publicly known, and therefore need not be described. Figures 3 and 4
are end views of the gas regulator.
Having described the nature of my said Invention, and in what manner the
same is or may be performed, I wish it to be understood that I do not claim
Invention
any of the parts taken separately; but that what I claim as my
are, the improvements herein-before described for regulating the amount of
pressure of gas at which the valve h will be closed.
In witness whereof, I, the said Charles Tiot Judkins, have hereunto set
my hand and seal, this Tenth day of May, in the year of our Lord
One thousand eight hundred and fifty-nine.
Signed, sealed, and delivered by the above-
named Charles Tiot Judkins, in the
presence of
