My object is to form a hydraulic valve for high pressure, which while being
perfectly watertight can be more quickly "cut off" or turned “
possible with the valves now in use.
I accomplish this by fitting between two suitable cheeks of metal in one or both
of which are sunk circular depressions of suitable size, a suitable disc of metal
of suitable thickness from one side of which a suitable segment has been removed.
The two cheeks are bolted or otherwise fastened together and by means of a suit-
able rod, fitted to the centre of the disc, it can be turned from the outside.
A suitable orifice, or channel, for the passage of the water is cut between the
cheeks to correspond with the segment cut from the disc, which upon being turned
closes or opens the orifice through which the water passes, a quarter turn being
sufficient to close or open it completely.

An Improved Hydraulic Valve.
I, HENRY SIDEBOTTOM, of Flixton Road, Urmston, in the County of Lancaster,
Agent, 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 object is to form a hydraulic valve for high pressure, which while being
"C turned on "than is possible
perfectly watertight can be more quickly "cut off" or
with the valves now in use. I accomplish this by fitting between two suitable
cheeks of metal (in one or both of which are sunk suitable circular depressions of
the required size,) a suitable disc of metal of suitable thickness, from one side of
which a suitable segment has been removed.
The two cheeks are bolted or otherwise fastened together and by means of a
suitable rod fitted to the centre of the disc it can be turned from the outside.
A suitable orifice, or channel, for the passage of the water is cut between the
cheeks to correspond with the segment cut from the disc.

page_text: The disc upon being turned closes or opens the orifice through which the water
passes, a quarter turn being sufficient to close or open it completely.
Referring to the drawings sent herewith:
-
Fig. 1 shows a cross section of my improved valve, Fig. 2 a plan section and
Fig. 3 a plan section of a threeway valve of my improved construction―
a indicates the disc, fitted between_cheeks bb, in which is cut segment c
through which the water can pass, when it is in the position shown, from opening
of channel d to channel e, but which is moved by a quarter turn of rod f into
position shown by dotted line g closing the inlet d and cutting off the supply.
It will be perceived that it can be used equally well the reverse way if desired,
and that in Fig. 3 the water from inlet can be allowed to flow out by both
outlets and k, or by a quarter turn either of them can be cut off, and by a half
turn the supply inlet h completely closed.
It will also be perceived that four or more channels either inlets or outlets can
be controlled in the same manner, size or convenience being the only obstacles.
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:-
'
The combined apparatus substantially as described and shown herein before and
in the accompanying drawings, for the purposes set forth...
