Improvements in Straight Way Cocks or Valves.
I SIDNEY MOORHOUSE of Victoria Works Staleybridge in the County of Lancaster
Brassfounder do hereby declare the nature of my Invention to be as follows:-
.
My Invention relates to cocks or valves for controlling the flow of fluids and
particularly to the cases wherein the thoroughfare is closed by means of two valves
or shutters which are pressed in opposite directions against valve seatings as in the
case of the ell known Peate valve. In the said Peate valve the two valves are pressed
against the valve seatings by means of a double wedge acting upon inclines formed
upon the backs of the valves.
When the thoroughfare is opened the two valves are permitted to move away from
the valve seatings so that grit and dirt can get between the two faces of the valve and
seating, such grit and dirt tending to cut and wear the surfaces and prevent the
perfect closing of the thoroughfare. To remedy this defect 1 employ a spring to keep
the inclines on the valves against the wedge or cone upon the spindle so that the two
valves are always pressed against the seating faces by the re-action of such spring.
In the construction which I have adopted the two valves are so shaped as to form a
box when put together, such box enclosing a spiral spring which surrounds the spindle
and bears by one end upon the shoulders of the double wedge and by the other end
upon an inner end of the said box. When the thoroughfare is opened the valves
are kept in contact with the seating faces by the re-action of the spring. In the
cases of large valves more than one spring may be used. When the cock is in use it
may not in all cases be necessary to screw the wedge tightly down as the spring
might have sufficient closing effect but when necessary the valves can be tightly
wedged against the seating faces as in the case of the Peate valve.

Improvements in Straight Way Cocks or Valves.
I SIDNEY MOORHOUSE of Victoria Works, Staleybridge, in the County of Lancaster,
Brassfounder, 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 and accompanying drawings :-
My Invention relates to cocks or valves for controlling the flow of fluids and
particularly to the cases wherein the thoroughfare is closed by means of two valves or
shutters which are pressed in opposite directions against valve seatings as in the case
of the well known Peate valve. In the said Peate valve the two valves are pressed
against the valve seatings by means of a double wedge acting upon inclines formed
upon the backs of the valves. When the thoroughfare opened the two valves are
permitted to move away from the valve seatings so that grit and dirt can get between
the two faces of the valve and seating, such grit and dirt tending to cut and wear the
surfaces and prevent the perfect closing of the thoroughfare. To remedy this defect
I employ a spring or springs to keep the inclines on the valves against the wedge or
cone upon the spindle so that the two valves are always pressed against the seating
faces.
In order that my Invention may be clearly understood I will describe the same

page_text: more fully with reference to the accompanying drawings wherein Fig. 1 is a sectional
view of a complete stop valve or cock for controlling the flow of fluids constructed in
accordance with my Invention. Figs. 2 and 3 illustrato modifications which may be
made in the construction of the parts affected by my invention. In Fig. 1 a is the
body of the valve which is provided with a bonnet a¹ and screw and hand wheel b
these parts being of an ordinary or of any suitable formation and being subject to
variation as required to suit differences in the sizes of valves and in the purposes for
which they may be intended to be used. The thoroughfare through the body is
closed by a valve c which is fitted to slide up and down in the valve chamber and is
formed in two parts. Within the space between the two parts of the valve is a nut d
which engages with the thread of the screw 6 and is formed with two inclined faces
which bear against correspondingly inclined faces c¹ which are formed on the insides
of the two parts of the valve. When the screw is turned in the direction which will
force down the nut the two parts of the valve are pressed in opposite directions against
the seating faces or walls of the valve chamber and close the thoroughfare. In some
cases the said valve chamber would be formed with two flat walls against which
the two parts of the valve would be pressed but in other cases and especially in
the cases of small valves the said chainber might be bored out and the valve be
turned to fit the chamber. In the latter case the nut d might for convenience of
construction be formed with a cone adapted to fit hollow conical seatings formed on
the two parts of the valve. The upper part of the valve is formed with inwardly
projecting flanges c³ which serve to keep in place a spiral spring e which surrounds
the nut the two parts of the valve forming as it were a box which encloses the nut
and the spring. The said spring is compressed between a shoulder upon the nut
and the flanges and by bearing upon the nut as a fixed fulcrum tends to thrust
the valve in a direction which would be upward in the drawing. It will be seen
that when the two parts of the valve are pushed upward they are at the same time
moved into closer contact with the wall or walls of the valve chamber owing to the
wedge action of the nut. When the screw is turned to open the valve the spring
carries the parts of the valve upward and keeps them in sliding contact with the
walls or seating faces of the valve chamber and when the valve is being closed the
spring sustains. the parts of the valve and maintains the said sliding contact. For
some purposes or at certain times the contact between the valve and its seating or
seatings due to the action of the spring may be sufficient but whenever necessary
the parts of the valve can be tightly wedged against the seating faces by turning
the screw b.
In Fig. 2 two spiral springs are applied one above and one below the wedge part
of the nut. The additional spring e acts upon inclined faces formed upon the two
parts of the valve and tends to separate the parts and thereby to keep the valve in
contact with the seating faces.
In Fig. 3 a single spring is used and the parts of the valve are thrust apart by the
action of a conical collar b¹ upon the screw and of a fixed cone f at the bottom of
the valve chamber. The spring bears by each end upon the inclined or conical ends
of the box formed of the two parts of the valve so that such parts are thrust apart at
- both ends.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
(1) In a valve or cock of the indicated type the combination of a spiral spring or
of spiral springs with the other parts constituting the complete valve as set forth and
indicated.
'
(2) In a stop valve or cock the spiral spring applied between the two parts of the
valve o so as to tend to separate such parts substantially as and for the purpose set

page_text: (3) In a stop valve the two parts of the valve c formed as a box and enclosing a
spring or two or more springs which tend to separate such two parts substantially as
and for the purpose set forth and indicated.
