IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF GAS, AND IN FITTINGS CONNECTED THEREWITH, WHICH ARE ALSO APPLICABLE TO OTHER PURPOSES
Year: 1868

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, AND IN
FITTINGS CONNECTED THEREWITH, WHICH ARE ALSO APPLICABLE TO OTHER
PURPOSES."
Sealed the 9th April 1869, and dated the 13th October 1868.
PROVISIONAL SPECIFICATION left by the said William Thomas
Sugg at the Office of the Commissioners of Patents, with his
Petition, on the 13th October 1868.
I, WILLIAM THOMAS SUGG, of Vincent Works, Vincent Street, in the
City of Westminster, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS EOR REGULATING THE SUPPLY OF GAS, AND IN
FITTINGS CONNECTED THEREWITH, WHICH ARE ALSO APPLICABLE TO OTHER PUR-
POSES," to be as follows:-
This Invention has reference in the first place to further improvements
in apparatus for regulating the supply of gas, and for which Letters
Patent, No. 2277, bearing date the Fifth day of September, One thousand
eight hundred and sixty-six, were granted to me; and consists in the
mode of securing the flexible diaphragm within the case of the governor

page_text: or regulator. This is effected by forming a metal ring with three, or
more, or less inclined planes (or segments of a three, or more, or less
threaded screw) upon its periphery. On the edge of the ring notches
are cut, which allow it to pass over studs or projections either cast on
the interior of the case or otherwise fastened to it. These studs are
undercut so as to admit of the inclined planes of the ring, when it is
turned partially round, taking a bearing upon the said studs and thus
press the ring down to a shoulder in the body of the lower case, so that
whatever substance is placed between the ring and the shoulder is
tightly gripped thereby. Notches are cut in the upper case of the
governor, which allow of its dropping over stops cast on the periphery
of the ring, the object being that the cover when put on and turned
slightly round shall press against the stops on the ring, force it tightly
home, and retain it there with the assistance of screws, until the screws
are withdrawn and the ring released by an opposite movement of the
cover. It will be obvious from the foregoing that if the flexible
diaphragm be placed between the ring and the before-mentioned
shoulder it will be held firmly in position until intentionally removed.
The foregoing method of securing the flexible diaphragm is applicable
to governors of all sizes, whether they be used for public lamp, private
consumption, or street main use.

The Invention in the second place relates to the construction of the
"
cones or fittings attached to the top of the governor and in which
the burner is inserted. It is proposed to cast these in soft metal, that
is to say, a mixture of zinc or lead, tin and antimony, or other suitable
compound, to make them smooth or polished internally of a taper form,
and to insert within the tube a conical or curved plug of such diameter
as to leave a narrow concentric passage for the gas to pass through, and
thus distribute it uniformly to every part of the burner. This improve-
ment may be applied to fittings generally independent of those con-
nected with the governors before mentioned. For the purpose of
facilitating the manufacture and lessening the cost of production, together
with other advantages, both the soft metal rings of the governors and
the cones just described are preferred to be (though not indispensably
necessary) cast in polished brass, iron, steel, or other metallic moulds.
When, however, the rings are too large to admit of this material and
process being adopted, the ordinary method of casting or constructing
must be resorted to, the general form as described being retained.

page_text: 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 13th April 1869.
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 Thirteenth day of October, in the year
of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said William Thomas Sugg, Her
special licence that I, the said William Thomas Sugg, my exccutors,
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, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF GAS, AND IN
FITTINGS CONNECTED THEREWITH, WHICH ARE ALSO APPLICABLE TO OTHER PURPOSES,"
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 marked thereon, that is to say :-
This Invention has reference in the first place to further improvements
in apparatus for regulating the supply of gas, and for which Letters
Patent, No. 2277, bearing date the Fifth day of September, One thousand
eight hundred and sixty-six, were granted to me.

page_text: In order that the Invention may be more perfectly understood
Drawings are attached hereto, of which the following is an explanation:-
Fig. 1 is a sectional elevation of the governor and burner cone; Fig. 2
is an elevation of the ring; Fig. 3 is a plan of the governor with the
cover removed; and Fig. 4 is a plan of the under side of the cover.
The action and general arrangement of the apparatus is similar to
that described in the Specification of the Letters Patent before alluded
to, but the method of securing the flexible diaphragm in its place is
different, and consists in forming a metal ring A, Fig. 1, with three or
more or less inclined planes (or segments of a three, or more, or less
threaded screw) upon its periphery, shown at B, Fig. 2. On the edge of
the ring notches C are cut, which allow it to pass over studs or pro-
jections D either cast on the interior of the case or otherwise fastened to
it. These studs are under cut so as to admit of the inclined planes of
the ring A when it is turned partially round taking a bearing upon the
said studs D and thus press the ring down to a shoulder in the body of
the lower case, so that whatever substance is placed between the ring and
the shoulder is tightly gripped thereby. Notches E are cut in the upper
case of the governor, which allow of its dropping over the stops F cast
on the periphery of the ring, the object being that the cover when put
on and turned slightly round shall press against the stops or studs I on
the ring, force it tightly home, and retain it there with the assistance of
screws G until the screws are withdrawn and the ring released by an
opposite movement of the cover. It is, however, by no means im-
perative that the turning of the cover should be the means employed
to thrust the ring home, as a triangular or other suitably forked tool
or tools may be used for the purpose. It will be obvious from the
foregoing that if the flexible diaphragm H be placed between the ring
and the before-mentioned shoulder it will be held firmly in position until
intentionally removed.
The foregoing method of securing the flexible diaphragm is applicable
to governors of all sizes, whether they be used for public lamp, private
consumption, or street main use.
The Invention in the second place relates to the construction of the
"cones" or fittings I attached to the top of the governor and in which
the burner is inserted. It is proposed to cast these in soft metal, that is
to say, a mixture of zinc or lead, tin and antimony, or other suitable
compound to make them smooth or polished internally of a taper form

page_text: and to insert within the tube a conical or curved plug J, Fig. 1, of such
diameter as to leave a narrow concentric passage between it and the side
of the cone I for the gas to pass through, and thus distribute it
uniformly to every part of the burner. This improvement may be
applied to fittings generally independent of those connected with the
governor before mentioned. For the purpose of facilitating the manu-
facture and lessening the cost of production, together with other
advantages, both the soft metal rings of the governors and the cones
just described are preferred to be (though not indispensably necessary)
cast in polished brass, iron, steel, or other metallic moulds. When, how-
ever, the rings are too large to admit of this material and process being
adopted the ordinary method of casting or constructing must be resorted
to, the general form as described being retained. Similar letters in the
different Figs. refer to the same parts of the apparatus.
Having now described and particularly set forth the nature of this
Invention, and the manner in which the same is or may be carried into
effect, I would observe in conclusion that I do not confine myself to the
precise details described or referred to, as variations may be made without
deviating from the general means by which these improvements are pro-
duced; but what I consider to be novel and original, and therefore claim
as the Invention secured to me by the herein-before in part recited
Letters Patent is, the construction of gas governors or regulators and
fittings connected therewith or otherwise applied to fittings generally,
substantially as herein described.
In witness whereof, I, the said William Thomas Sugg, have
hereunto set my hand and seal, this Thirteenth day of April,
in the year of our Lord One thousand eight hundred and sixty-
