PROVISIONAL SPECIFICATION left by the said William Henry Moseley at
the Office of the Commissioners of Patents on the 30th October 1882.
WILLIAM HENRY MOSELEY, of Derby, in the county of Derby, Engineer,
"IMPROVEMENTS IN COCKS OR VALVES FOR CONTROLLING OR REGULATING THE FLOW
OF WATER, STEAM, GAS OR OTHER FLUIDS,"
This invention has for its object improvements in cocks or valves for the purpose
of regulating or controlling the flow of steam gas or liquids, and consists in
forming in the shell or body of the cock or valvo a cylindrical facing in which
slides an elastic ring of cast iron, brass, or other metal, regulated by a screwed
spindle; lever or other device. The elasticity of the ring keeps it tight against the
face and forms a perfect joint, keeping sediment or grit from getting between the
faces.
When the cock or valve is used for liquids or gases possessing corrosive properties
the working parts must be constructed of, or coated with, materials capable of
resisting such action.

IMPROVEMENTS IN COCKS OR VALVES FOR CONTROLLING OR REGULATING THE FLOW
OF WATER STEAM GAS OR OTHER FLUIDS
This invention has for its object improvements in cocks or valves. for the purpose
of regulating or controlling the flow of steam, gas or liquids, and consists in forming
in the shell or body of the cock or valve a cylindrical facing on which slides an
elastic ring of cast iron, brass, or other metal regulated by a screwed spindle, lever,
or other device. The elasticity of the ring keeps it tight against the face and
forms n perfect joint, keeping sediment or grit from getting between the faces.
When the cock or valve is used for liquids or gases possessing corrosive properties,
the working parts must be constructed of, or coated with materials capable of
resisting such action.
Heretofore nearly all stop-valves have been liable to tho objection of the valve
falling away from its facing, when opened, and in those rare cases where it is not
50, springs and other devices, which soon get out of order, have been used to
obviate this serious defect.
I
My present invention while always keeping the valve tight up against its facing,
contains in the valve itself the elasticity requisite for the n
th
The accompanying drawings shew my present invention applied in various ways.
Fig. 1 is a sectional elevation.
Fig. 2 is a sectional plan of a stop-cock suitable for boilers, steam engines, &c. .
Fig. 3 is a back elevation of the same.
Fig. 4 is a plan of a ring with split boss and two arms.
i
A is the valve box or casing, which may be made of cast iron or other suitable
metal, and of any required dimensions, B is a ring of suitable metal which is first
sprung in by the lugs C C' and (while being thus sprung in) is turned the same
diameter that the shell or facing A¹ is bored, D D' are two small stops to prevent
the ring from turning. These are not required when the valve is opened by a lever
and spindle.
The apparatus (of any known kind) used for cramping in the ring is. then
removed, and the ring being placed in its seat contains within itself sufficient
elasticity to cause it to spring strongly against the boro of the facing, thus always
keeping it up against the face, whether open or shut, ensuring a perfect joint when
closed, and by the act of closing, cleaning away from the facing any deposit or grit
which may have settled there.
A lug E is cast on the ring with a central hole bored in it for the passage of the
spindle which actuates the valve. It will be seen in the plan view, Fig. 2, that the
ring has a space between the lugs C C' thus leaving the passage always open at the
back of the valve and permitting the fluid or gas to flow inside the ring, that when
the valve is closed there is no part whatever of the facing in which the ring slides
exposed to the action of the steam, fluid &c. It is applicable where two or more
passages are required. The ring can be split in any part, and I find it frequently
advantageous to use a ring with a split boss and two arms as shewn in Fig. 4.

page_text: The principle of the valve is applicable for steam, hydraulic, gas and all other
purposes where a stop-cock is required.
In the case of small valves such as for beer or liquors, the valve may be closed
by a spring on the spindle and opened by a lever for the sake of quickness, instead
of screwing down, but I do not bind myself to, or claim, any special mode of
operating the valve.
I am aware that in itself the mere making of a spring ring is not novel; such
rings being greatly used for packing pistons and pump buckets, but having now
described my invention, and the best mode known to me of performing the same, I
would have it understood that I claim :-
The construction of stop-valves with the valve proper (opening and closing the
passage or passages) made of a metallic ring held by its own elasticity against, the
facing or bore of the shell in which it slides, as and for the purposes described.
In witness whereof I the said William Henry Moseley have set my hand
and seal this Twentieth day of February in the year of our Lord one
thousand eight hundred and eighty three.
