PROVISIONAL SPECIFICATION.
Improvements in Valves for Water and other Liquids.
I, ROBERT WILLIAM ANDERSON of 93 Mulgrave Street, Liverpool in the
County of Lancaster, Engineer do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in valves for water and other liquids and
its object is to so arrange a valve that it is allowed freedom to seat itself accurately
on its metallic scat, that packing for the valve spindle is dispensed with and that
the parts may be few, simple and readily accessible while the external appearance
is neat and attractive.
In carrying my invention into effect I arrange my valve tap with a main casting
of cylindrical form to which the water supply branch is attached or on which it is
formed in any convenient way.
I invert my main casting and insert from below a tubular or drilled valve stem
on which is preferably formed a circular milled disc, wheel or handle.
The valve stem is screwed into the cylindrical case and carries at its upper and
inner end a flat or conical seated valve, which valve is pressed home to its seat by
a spiral spring acting between the valve or rather screw down spindle and the valve.
The valve is socketed by a square or round projecting piece to the screw spindle
and so, although thrust to its seat by the pressure brought to bear by the spring
yet it is sometimes turned round on its seat as it is pressed home. In this manner
it is caused to displace particles of grit and remain true to its seat.
Suitable apertures drilled or otherwise formed in the valve stem or screw down
portion permits access of water when the valve is opened to a central aperture also
in the screw down part, so that when the dise or wheel handle is rotated to obtain
water or other liquid supply the water flows through a tube or aperture forming
the centre, of which the end projects sufficiently below the dise or wheel to guide
the water efficiently.
Above the screwed part of the stem a groove is cut and a hole leads from this
groove to the exit aperture to drain off any leakage which would otherwise pass
the screw and cause such leakage to discharge at the centre. The spring is made
sufficiently strong to hold the valve closed against the water pressure.
The movement of the screwed stem is also limited in any convenient way as by a
groove and pin.
By this arrangement of inverted handle and valve stem with discharge or exit
through the stem I am enabled to entirely dispense with packing glands for the
stem as the whole pressure of the water bears upon the valve only and not upon
the stem, water having access to the stem only when discharging.
The invention may be modified in several ways, the valve may carry for example
the hollow exit stem which may pass through the centre of the screw and handle
disc or wheel, while the spring may make the connection between the screw handle
and the valve, by surrounding the discharge pipe, in which I bore a hole in order
to drain from the cavity or recess containing the spring.
A spindle from the valve may likewise be prolonged and screw into the metal on
the water pressure side of the valve and in this case, the handle portion is not
screwed but is held ou in one position by pin, washers or other device. It is con-
nected by square recess and projection to the valve to rotate and so screw to its
seat.
In another modification, I prolong the valve spindle to the pressure side and
cause it to carry a small piston working in a small cylinder and I thrust the valve

page_text: to its seat by a central projection from the screw handle; in this case also I
dispense with the use of springs.
The valve may be attached to the rotating or screw down part by lugs and pin
with the spring surrounding the connecting part, and in another modification in
which the valve screws to its seat the screw may be formed in the valve seat and
suitable holes lead through when it is opened.
In these several modifications a characteristic feature of my invention is retained
which consists of the inverted handle, through the centre part of which the dis-
charge of water occurs; and further the valve is in all cases pressed home to its
seat against the water pressure.

COMPLETE SPECIFICATION.
Improvements in Valves for Water and other Liquids.
I, ROBERT WILLIAM ANDERSON, of 93, Mulgrave Street, Liverpool, in the
County of Lancaster, 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 improvements in valves for water and other liquids and
,its object is to so arrange a valve that it is allowed freedom to seat itself accurately
on its metallic seat, that packing for the valve cylinder is dispensed with and that
the parts may be few, simple and readily accessible while the external appearance
is neat and attractive.
In the two sheets of accompanying drawings at Figures 1 to 18 inclusive. I have
illustrated my invention as applied to various modifications, and throughout the
drawings the same reference letters are used for the same or similar parts.
and 3
In carrying my invention into effect I arrange my valve tap (Figures 1,
Sheet 1) with a main casting a of cylindrical form to which the water supply
branch is attached or on which it is formed in any convenient way.
As shown in Figure 1 the branch e is cast in one with a.
I invert my main casting a and insert from below a tubular or drilled valve stem b
on which is preferably formed a circular milled disc ', wheel or handle. The valve
stem is screwed into the cylindrical case a and carries at its upper and inner end
a flat seated valve d which valve d is pressed home to its seat by a spiral spring e
acting between the valve or rather screw down spindle and the valve d, as shown
in section at Figure 2 and in clevation in Figure 3 on a larger scale. The valve d
is socketed by a square or round projecting piece d to the screw spindle b and so
although thrust to its seat by the pressure brought to bear by the spring e yet it is
turned round on its seat as it is pressed home. In this manner it is caused to
displace particles of grit and remain true to its seat.
Suitable apertures 3 drilled or otherwise formed in the valve stem or screw
down portion permit access of water when the valve is opened to a central aperture 2
also in the screw down part, so that when the disc or wheel handle is rotated to
obtain water or other liquid supply, the water flows through a tube or aperture 12
forming the centre of which the end projects sufficiently below the disc or wheel b
to guide the water efficiently.
Above a portion of the screwed part of the stem ba groove 65 is cut, and a hole k
leads from this groove to the exit aperture to drain off any leakage which would
otherwise pass the screw and cause such leakage to discharge at the centre. The
spring e is made sufficiently strong to hold the valve closed against the water
pressure. The movement of the screwed stem is also limited in any convenient
way as by the groove and pin . By this arrangement of inverted handle and
valve stem with discharge or exit through the stem I am enabled to entirely

page_text: dispense with packing glauds for the stem as the whole pressure of the water bears
upon the valve only and not upon the stem, water having access to the stem only
when discharging.
The invention may be modified in several ways one of which is shown at Figure 4
and one at Figure 7, the valve d may carry for example the hollow exit stem ²
which may pass through the centre of the screw and handle disc or wheel
while the spring may make the connection between the screw handle, and the
valve d, by surrounding the discharge pipe, in which I bore a hole in order to
drain from the cavity or recess containing the spring.
"
This arrangement is shown at Figure 4 where the nut holds the valve against
the action of the spring, when is turned to open.
Figure 7 shows another modification where the valve d is made tubular below
at and carries the spring e in a recess but the edge of the tube is turned over
inside to hold against the spring.
Figure 5 shows an external elevation of my valve when the water supply pipe c
is bent and made separate from a but attached to it.
Figure 6 illustrates a modification where the wheel is arranged with spokes.
Figures 8 and 9 show another arrangement of the valve d with the spring e con-
tained in a hollow.
Figures 10 and 11 show the spring within the valve and the valve retained by a
screw pin.
In Figures 12 and 13 the valve d has a hollow e filled with rubber.
A spindle from the valve d may likewise be prolonged and screw into the
inetal on the water pressure side of the valve as shown in Figure 15 and in this case
the handle portion is not screwed but is held in one position by a pin, washers
or other device. It is connected by square recess and projection to the valve and
when rotated it causes the valve to rotate and so screw to its seat.
In another modification, Figure 14, I prolong the valve spindle to the pressure
side and cause it to carry a small piston or guide h' working in a small cylinder,
and I thrust the valve di to its seat by a central projection from the screw handle b ;
in this case also I dispense with the use of springs.
The valve may be attached to the rotating or screw down part by lugs and pin
as shown at Figures 8 to 13 inclusive with the spring surrounding or within the
connecting part.
At Figure 16 show a modification of my invention suitable for cylinder
drains and here the valve d is forced to its seat without the intervention of a
spring.
Figure 16 is a section and Figure 17 is an elevation but the external elevation
may also be as in Figure 19 where the admission end is at right angles to the
discharge b.

applicable to these valves when a spring washer
and the valve in order to allow a limited elastic
In these several modifications a characteristic feature of my invention is retained
which consists of the inverted handle, through the centre part of which the
discharge of water occurs; and further the valve is in all cases pressed home to its
seat against the water pressure.
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.) The stop cocks or valves for liquids, gases, or vapours, substantially as
hereinbefore described, with reference to Figures 1 to 18 of the accompanying
drawings, in which discharge of fluid takes place through the tubular screw down
or rotating portion.
(2.) A stop cock or valve in which a cylindrical body as a contains a screw down
or rotating tubular piece as b, through which fluid is discharged, the said fluid

page_text: gaining access to the aperture 2 by holes as ³, substantially as hereinbefore
described and illustrated in the accompanying drawings.
(3.) A stop cock or valve in which a spring connection is made between the
screw down piece, and the valve d by the methods herein before described with
reference to Figures 2, 3, 4, 7, 8, 9, 10, 11, 12 and 13 of the accompanying
drawings.
(4.) A stop cock or valve in which the valve d has a screwed stem as hor
extension as hand is seated by the rotation of a stem piece or screw piece the
said stem or screw piece being tubular substantially as hereinbefore described with
reference to Figures 14 and 15 of the drawings.
