PROVISIONAL SPECIFICATION.
Improvements in Stop Valves for High Pressure Steam,
and other Fluids.
I, GARRATT PAYNE of 28 Comyn Road Clapham Junction in the County of
Surrey Engineer do hereby declare the nature of this invention to be as follows:-
My invention relates to stop valves such as are described in the Specification
of my Patent No. 2451 dated 3rd February 1893.
The valve is as described in my aforesaid Specification constructed somewhat on
the principle of a sluice valve with one or two facing part or parts forming what
is called the gate or gates. The gates are mounted in a sling frame which is
connected to the main spindle so as to allow the latter to revolve independently
of the sling frame when required. The main spindle is not made hollow throughout
but is provided with a screwed recess at the top and at the bottom. Into the
screwed recess at the bottom is screwed the upper shank of the sling frame and
the gates are provided with pins which go through the wedged shaped holes in the
sling frame. The screwed recess at the top is provided with a screw on which is
freely mounted a friction cone which is capable of being jammed into a suitably
formed recess in the top of the hand wheel and the stud is provided with a handle
or lever to allow of its being turned to jamb the friction cone into the hand wheel
and to release it. The hand wheel is provided with an internal thread to form the
nut which raises and lowers the valve and when the valve has been lowered to its
proper position for closing, the friction cone at the top is caused to jamb, thereby
making the spindle and the hand wheel to all intents and purposes in one.
further turning the hand wheel the stud at the bottom of the spindle is caused
to be screwed out of the spindle more or less and in descending this causes the
wedge shaped sling or frame to force the gates apart.

COMPLETE SPECIFICATION.
Improvements in Stop Valves for High Pressure Steam,
and other Fluids.
I, GARRATT PAYNE of 28 Comyn Road Clapham Junction in the County of
Surrey, Engineer, 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 relates to stop valves for high pressure steam and other fluids such

page_text: as are described in the Specification of my Patent No. 2451 dated 3rd February
1893.
The accompanying drawing represents in part sectional elevation a representative
construction of valve made according to my invention.
The valve is as described in my aforesaid Specification constructed somewhat on
the principle of a sluice valve with one or two facing part or parts A (two being
here shewn) forming what is called the gate or gates. The facing parts A A are
mounted in a carrier ring or frame F which is connected to the main spindle E so
as to allow the latter to revolve independently of the said carrier ring or frame. The
main spindle E is not. made hollow throughout but is provided with a screwed
recess at the top and also at the bottom. Into the screwed recess at the bottom
is screwed the upper shank of the sling frame I and the facing parts A A are
provided with pins G, which may have rollers thereon if desired, and which go
through the wedge-shaped holes in the sling frame I. The screwed recess at the top
of the spindle E is provided with a screwed stud D on which is freely mounted a
friction cone D which is capable of being janined into a suitably formed recess in
the top of the hand wheel E¹ and the screwed stud D is provided with a handle or
lever D to allow of its being turned to jamb the friction cone D¹ into the hand
wheel E and to release it. Instead of using a hand wheel the valve spindle may
be raised and lowered by a lever or in any other convenient manner. The hand
wheel E¹ is provided with an internal thread to form the nut as shewn and the latter
is capable of revolving in a bearing E attached to the valve casing for the purpose.
of raising and lowering the valve. When the valve has been lowered to its proper
position for closing, the friction cone D at the top is caused to jamb, thereby
making the spindle E and the hand wheel E¹ to all intents and purposes in one. On
further turning the hand wheel E¹ the screwed stud or shank I at the bottom of
the spindle E is caused to be screwed out of the spindle more or less and in
descending this causes the wedge-shaped sling or frame I to force the facing parts A
apart until they make joint with the seatings B B. It is however evident that I do
not limit myself to the exact means shewn for raising and lowering the spindle and
for causing it to operate the sling frame as other means may be devised for carrying
out these operations.
Although I have only shewn my invention as applied to a valve with two facing
parts A A it is evident, without further description, that it may be applied equally
well to valves with only one gate or facing part as described for instance in my
afore mentioned Specification.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. A sluice or gate valve having one or two facing part or parts for making joint
with a seat or seats, in the valve casing said facing part or parts being mounted in
a carrier ring or frame connected to a spindle operated in any convenient manner
for raising and lowering the facing part or parts, means for revolving the spindle
for actuating a sling frame supported in the carrier ring, the sling frame being
provided with a wedge-shaped hole or holes engaging with a pin or pins on
the facing part or parts with or without a roller or rollers mounted thereon, said pin
or pins or roller or rollers being adapted for bringing the facing part or parts tightly
up against the seat or seats or away from same substantially as set forth.
2. A sluice or gate valve having one or two facing part or parts for making joint
with a seat or seats in the casing, said facing part or parts being mounted in a
carrier ring or frame connected to a spindle for raising and lowering the facing part
or parts by means of a nut formed in one with a hand wheel or the like and a
friction device for causing the coupling of the hand wheel and the spindle for the
purpose of moving the sling frame which is provided with a wedge shaped hole or
holes engaging with a pin or pins on the facing part or parts, with or without a
roller or rollers mounted thereon, said pin or pins or roller or rollers being adapted

page_text: for bringing the facing part or parts tightly up against the seat or seats or away from
same substantially as set forth.
3. The construction of valve as described and shewn on the drawing.
