PROVISIONAL SPECIFICATION.
Improvements in Valves for Water, Steam, or other Liquids or
Gases.
I, WILLIAM ROBERT SYKES Senior, of 15 Vernon Road, High Street,
Clapham, in the County of Surrey, Telegraph Engineer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in valves for water, steam or other liquids,
or gases, and consists that instead of applying the pressure direct onto the inlet pipe
for the purpose of preventing the escape of fluid, that is to say, instead of applying
a vertical pressure (I use the word "vertical" as distinct from "horizontal," the
former pressure operating the valve direct down on to the seating, the latter moving
it sideways to close or open the inlet aperture), I employ a horizontal movement by
means of the screw.
In those cases where pressure is applied to the valves vertically and where no
fibrous packing is used, that is to say, where it is metal against metal, if any
unevenness occurs, or any grit or other material by chance gets on to the face
of the valve or on the valve seating, when vertical pressure is applied such grit
instead of being moved out of the way is ground by the pressure of the screw on
to the valve creating great unevenness and damage to the valve by racing. With
my invention I provide against this by the horizontal movement of the valve
across the inlet pipe by means of the screw, that is to say, that any grit or
dirt that may be on the face of the valve or on its seating is brushed aside by
the movement of the valve across the inlet pipe seating from one side to the
other.
The valve is made hollow to take a spring and fits on to a seating of the nut
worked by the screw. The spring keeps the valve normally tight against the inlet
aperture.

Improvements in Valves for Water, Steam, or other Liquids or

I, WILLIAM ROBERT SYKES, Senior, of 15 Vernon Road, High Street,
Clapham, in the County of Surrey, Telegraph 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, steam, or other liquids,
or gases, and consists that instead of applying the pressure direct on to the inlet
pipe for the purpose of preventing the escape of fluid, that is to say, instead of
applying a vertical pressure (I use the word "vertical" as distinct from "horizontal,"

page_text: the former pressure operating the valve direct down on to the seating, the latter
moving it sideways to close or open the inlet aperture), I einploy a horizontal
movement by means of the screw.
In those cases where pressure is applied to the valves vertically and where no
fibrous packing is used, that is to say where it is metal against metal, if any
unevenness occurs, or any grit or other material by chance gets on to the face
of the valve or on to the valve seating when vertical pressure is applied instead of
such grit being moved out of the way it is ground by the pressure of the screw on to
the valve or its seating creating great unevenness and damage to the valve by racing.
With my invention I provide against this by the horizontal sliding movement of
the valve across the inlet pipe by means of the screw, that is to say, that any grit
or dirt that may be on the face of the valve or on its seating is brushed aside by
the movement of the valve across the inlet pipe (valve seating) from one side to
the other.
In order that my invention may be better understood and more readily carried
into effect I will describe it with reference to the accompanying drawing
:-
a is the handle of the tap on the lower portion of which is formed a screw
thread & which works through a block or nut c provided with a hollow or cup like
portion d containing a spring e; over this springe and cup d the hollow valye f
fits. g is the inlet aperture for the water or other liquid which is closed by means
of the valve fas hereinafter described.
In order to prevent leakage at the head of the tap through upward pressure
of the water, a passage h is made in the threaded or lower portion of the
handle a which operates the valve, such passage h forming a junction with the
passage leading to the outlet pipe k, so that any water finding its way to
the head of the tap would escape by means of the hole / down through passage h
and out at k.
The action of my invention is as follows:-
=
When it is desired to close the inlet aperture 9, cutting off the flow of water,
the handle a is turned in the ordinary manner which by means of its thread b
working in the nut c moves the valve facross the aperture 9, the spring e being
the means of keeping the valve pressed well home on its seating. It will be
seen that, as before mentioned, should any dirt or grit be upon the valve or its
seat the sliding movement of the valve across the inlet aperture will brush it
aside.
I am aware that taps have been constructed before in which the valve has been
pressed down on its seating by means of a spring, such spring however being com-
pressed by the extra turning of the handle. I, therefore, do not lay any claim to
the spring as described.
With iny invention the turning of the handle does not give variation of pressure
on the spring, the screw being only used to move the valve across the aperture g,
whereas in prior inventions the screw has been used to force the valve down on to
its scating, making the valve solid with the seating, at the same time compressing
the spring.
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 :-
A sliding valve operated by means of the screw through the turning of the
handle, substantially as herein described and as illustrated in the accompanying
drawing.
