IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF GAS
Year: 1874

page_text: LETTERS PATENT to William Thomas Sugg, of Vincent Works,
Vincent Street, in the City of Westminster, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF GAS.”
Scaled the 3rd November 1874, and dated the 5th May 1874.
PROVISIONAL SPECIFICATION left by the said William Thomas Sugg
at the Office of the Commissioners of Patents, with his Petition, on
the 5th May 1874.
I, WILLIAM THOMAS SUGG, of Vincent Works, Vincent Street, in
the City of Westminster, do hereby declare the nature of the said
Invention of "IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF
GAS," to be as follows:-
This Invention has reference to modifications or improvements upon
apparatus for regulating the supply of gas for which Letters Patent,
No. 2277, dated the Fifth day of September, 1866, No. 3133, dated
October 13, 1868, and No. 2841, dated September 26, 1872, were granted
to me, and relates more especially to the latter. It consists in either
attaching to the hollow valve spindle of the governor and above the

page_text: diaphragm a burner nib of steatite or other suitable substance with a
slit, orifice, or orifices exactly or as nearly as may be corresponding in
size with the burner where the gas is consumed, or the nut which
fastens the diaphragm and shield to the hollow valve spindle may be so
made as to admit of the insertion of a screw, the conical or other
suitably shaped point of which enters the hollow spindle. By turning
the screw the size of the outlet or gas way from the hollow spindle to
the chamber above the diaphragm and beneath the burner where the
gas is consumed may be regulated with the greatest nicety and made at
pleasure to correspond with or vary from the size of the orifice in the
burner where conbustion takes place. In both cases the spindle is
hollow in the direction of its axis, and has one or more radial holes
which serve as channels to convey the gas from beneath the diaphragm
to the chamber above it.
Another modification or improvement consists in the application of a
spring or springs in lieu of or in addition to a weight for adjusting the
governor to the pressure at which it commences to regulate..
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Thomas Sugg in the Great Seal Patent
Office on the 5th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
THOMAS SUGG, of Vincent Works, Vincent Street, in the City of
Westminster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of May, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Thomas Sugg, Her
special licence that I, the said William Thomas Sugg, my executors,
administrators, and assigns, or such others as I, the said William Thomas
Sugg, 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, excrcise, and vend, within the United Kingdom of Great Britain

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF GAS," upon the
condition (amongst others) that I, the said William Thomas Sugg, 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 William Thomas Sugg, 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 accompanying
Drawings and to the letters and figures marked thereon, that is to
say:
This Invention has reference to modifications or improvements upon
apparatus for regulating the supply of gas for which Letters Patent,
No. 2277, dated the Fifth day of September, 1866, No. 3133, dated
October 13, 1868, and No. 2841, dated September 26, 1872, were granted
to me, and relates more especially to the latter. It consists in either
attaching to the hollow valve spindle of the governor and above the
diaphragm a burner nib of glass, steatite, or other suitable non-corrible'
substance with a slit, orifice, or orifices having a proportionate corre-
spondence according to the quality of the gas to be consumed by the
burner. The same object may be attained by piercing the diaphragm
and shield with suitably sized orifices, or the nut which fastens the
diaphragm and shield to the hollow valve spindle may be so made as to
admit of the insertion of a screw, the conical or other suitably shaped
point of which enters the hollow spindle. By turning the screw the size
of the outlet or gas way from the hollow spindle to the chamber above
the diaphragm and beneath the burner where the gas is consumed may
be regulated with the greatest nicety and made at pleasure to correspond
with or vary from the size of the orifice in the burner where combustion
takes place. In both cases the spindle is hollow in the direction of its
axis, and has one or more radial holes which serve as channels to convey
the gas from beneath the diaphragm to the chamber above it.
Another modification or improvement consists in the application of a

page_text: spring or springs in lieu of or in addition to a weight for adjusting the
governor to the pressurè at which it commences to regulate.
In order that the foregoing may be more easily understood, Drawings
are attached hereto, of which the following is a description:-Fig. 1 is a
sectional elevation of the regulator, A, being the case; B, the valve;
C, the diaphragm; and D, the burner nib attached to the valve spindle.
Fig. 2 is also a sectional elevation of a regulator differing only from the
other in size and the arrangement for regulating the size of the hole or
conduit from the lower chamber to the upper chamber. In this Fig.
A is the case; B, the valve; C, the diaphragm; and E, the screw, the
point of which is made to enter the conduit and increase or decrease the
size of the passage in accordance with the direction in which the screw
is turned.

Having now described and particularly set forth the nature of this
Invention, and the manner in which the same is or may be used or 1
carried into effect, I would observe in conclusion that I do not confine
or restrict myself to the precise details or arrangements which I have
described or referred to, as variations may be made therefrom without
deviating from the principles or main features of this Invention, but
what I consider to be novel and original, and therefore claim as the 2
Invention secured to me by the herein-before in part recited Letters
Patent is,―
Firstly. The regulation of the size of the orifice connecting the upper
