IMPROVEMENTS IN VALVES FOR STEAM WATER, GAS OR OTHER LIQUIDS OR Fluids
Year: 1886

page_text: I WILLIAM MARRABLE of No. 12 Warton Road High Street Stratford in the
County of Essex Carpenter do hereby declare the nature of my invention for
IMPROVEMENTS IN VALVES FOR STEAM WATER, GAS OR OTHER LIQUIDS OR Fluids
to be as follows:-
My invention has reference to valves constructed with a disc, but instead of
screwing the disc or valve downwards to its seating against the pressure of the
water or other liquid or fluid I cause it to be drawn upwards against its seating by
means of a screwed spindle passing through the body of the casting and terminating.
by a suitable wheel or handle, the upper side of the valve or tap casting is continued
so as to form a stuffing box with a nut or other suitable contrivance to form a
tight joint; upon the spindle of the disc or valve I form by preference a left handed
screw in order to draw the disc, against its seating, I cast the tap or valve with a
round inlet & outlet way the inlet being below the valve and the outlet being
above, the two communicating by means of a round hole cored through the partition
in the body of the casting, hitherto there has been considerable difficulty in fastening
the leather asbestos, or other suitable washer to the disc in order to obviate this
difficulty, I cast a collar on the spindle and the washer is screwed firmly against
this collar by means of a nut the thread to take this nut being right banded it is
readily manipulated against the working thread on the spindle which is a left
handed thread, the top face of the nut acts upon the washer which forms the stop
or means of shutting off the water or other liquid or fluid. The action of the
valve is as follows, by turning the spindle by means of the wheel or handle it is
caused to descend thereby opening the passage or way and admitting a free passage
to the water gas or other liquid or fluid and by turning the spindle the reverse
way the disc is drawn up against the seating provided for it in the body of the
casting. I sometimes form the disc with a suitable provision for the thread
& allow it to run in guides in this case the spindle does not rise in the stuffing
box but has only a revolving motion.

Improvements in Valves for Steam, Water, Gas, or other Liquids
or Fluids.
I WILLIAM MARRABLE of No. 12 Warton Road, High Street Stratford in the
County of Essex Carpenter do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
My invention has reference to valves constructed with a disc, but instead of
screwing the disc or valve downwards to its seating against the pressure of the
water or other liquid or fluid, I cause it to be drawn upwards against its seating
by means of a screwed spindle passing through the body of the casting and
terminating by a suitable wheel or handle, the upper side of the valve or tap
casting is continued so as to form a stuffing box with a nut or other suitable
contrivance to form a tight joint, upon the spindle of the disc or valve I form by
preference a left handed screw, in order to draw the disc against its seating, I cast
the tap or valve with a round inlet and outlet way, the inlet being below the valve
and the outlet being above the two communicating by means of a round hole cored
through the partition in the body of the casting. Hitherto there has been con-
siderable difficulty in fastening the leather, asbestos, or other suitable washer to the
disc, in order to obviate this difficulty I cast a collar on the spindle and the
washer is screwed firmly against this collar by means of a nut the thread to take
this nut being right handed it is readily manipulated against the working thread
on the spindle which is a left handed thread, the top face of the nut acts upon the
washer which forms the stop or means of shutting off the water or other liquid
or fluid.
The action of the valve is as follows by turning the spindle by means of the
wheel or handle it is caused to descend thereby opening the passage or way and
admitting a free passage to the water, gas, or other liquid or fluid, and by turning
the spindle the reverse way the disc is drawn up against the seating provided for
it in the body of the casting. Instead of forming the thread in the body of the
casting I sometimes form the disc with a suitable provision for the thread and
allow it to run in guides, in this case the spindle does not rise in the stuffing box
but has only a revolving motion.
Having now described the nature of my invention I will proceed to describe
in what manner the same is to be performed, reference being had to the drawings
hereunto annexed and to the letters and figures marked thereon.
Fig. 1 is an elevation of my improved valve and Fig. 2 a similar elevation shewn
in section illustrating the working parts, Fig. 3 is a view of a spindle shewing a
different plan of fixing the washer in this case.the washer c¹ is left loose so that
the motion of the water causes it to constantly change its position and present a
different surface to the seating, Fig. 5 is another plan of fixing the washer, in this
arrangement a box h² with the washer c¹ is allowed to hang upon a ball or head at
the end of the screw so that if not square with the seating it will adjust itself
and ensure a tight joint. It will be seen by reference to Fig. 2 that the water

page_text: enters at a and passes through the opening b in the partition d in the body of the
casting when the valve spindle c is screwed down into the open position, when the
water passes away; when the spindle c is in the closed position as shewn in Fig. 2
the washer c is brought close against the seating formed on the partition d and
the water is shut off, while the pressure of the water from the main or other
service tends to keep the washer firmly against its seating and so prevent any
leakage. The spindle c is caused to rise and fall "when it is turned by means of
the handle e," by a left handed thread c³ which is formed upon it, a corresponding
thread being formed in the body of the valve at a¹. When the spindle is formed
as illustrated in Fig. 4 the washer c¹ is fixed against a shoulder at c³ by means of
the nut In Fig. 3 the spindle is cut off shorter and a short spindle or screw h
is screwed into it as shewn at h¹ and the washer c¹ is first slipped over it & rests
upon the shoulder h². The nut ƒ Figs. 1 & 2 is for the purpose of inserting and
fixing the washer c³.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I wish it to be under-
stood that I do not limit myself to the precise details herein before described and
illustrated but I declare that what I claim is :—
1st. The construction of the body of the valves with a partition cast in and
admitting the water or other fluids from the under side thereby tending to keep
the washer or valve tight against its seating substantially as described.
2. The construction of the spindle having a loose washer or ball joint for self
adjustment substantially as illustrated & described.
3. The combination of the several parts for the puposes specified substantially
as described and illustrated.
