hereby declare the nature of said invention for "IMPROVEMENTS IN VALVES OR
COCKS FOR CONTROLLING THE SUPPLY OF WATER AND OTHER LIQUIDS OR FLUIDS
to be as follows:-
"
The object of my Invention is simplicity of construction combined with great
strength and durability in apparatus or valves for controlling the supply of water
and other liquids or fluids.
According to my invention I make the body with by preference, in the case of
stop or bib cocks, a passage which may be of annular form; around the seating in
connection with this body I arrange a screw, said screw having a central passago
joining a side passage or passages and to which is fitted a nut having a solid top,
said nut also forming the valve; instead of a stuffing box I prefer using a washer
or cup leather although a stuffing box may be used if preferred, the valve scating
may be of any suitable material for different purposes.

FOR CONTROLLING THE SUPPLY OF WATER AND OTHER LIQUIDS OR FLuids
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
By my invention I attain simplicity of construction combined with great
strength and durability in valves or cocks for controlling the supply of water and
other liquids or fluids.
According to my invention I make the body or casting with a passage by the
side or around the valve seating in connection with which I provide a tubular
screw or screwed stem having a central passage and one or more lateral passages or
apertures joining the central passage. On this screw I fit a nut having a solid top,
said nut also forming the valve which can be screwed down on to the seat, thus
closing the valve by covering the aforesaid lateral aperture or apertures through
the tubular screw stem. Instead of the ordinary packed stuffing box and gland
I prefer in many cases to use a washer or cup leather. The seating may be of
leather or any other suitable material all according to the different purposes for
'which the valves are intended.
Figure 1 is a vertical longitudinal section, Figure 2 a vertical transverse section,
Figure 3 a side view and Figure 4 a plan with cover and seating removed of a stop
cock or valve specially applicable for large sizes. a is the body of valve with
annular passage
b round the scating-c is the cover or top casing with cup leather o
secured by cover f. The screw g is here shown fixed by means of a flange between
flanges on the body a and top casing c The screw is in this case formed with
side passages as shown at h, h¹ h. The nut or valve i is shown with a square top
so that the valve may if required be placed underground and worked by a
correspondingly square recessed key or box spanner from surface. The lower part
of nut or valve i is flanged and screws down on to the leather or other washer
seating on flange of screw g. I sometimes fit a washer on top of flange so that
when the valve is screwed up the washer is pressed against the inside top of
casing c and not only acts as an additional preventer of leakage but allows of the
packing or cup leather being replaced without shutting down the main and thus
saving time trouble and expense.
Figure 5 is a vertical sectional view of the upper part of a valve applicable as a
hydrant valve. a is the body on the outlet shank of which is fixed a scrow d, or
screw thread may be formed on the shank itself to connect to hose scrow or stand
pipe, or it may be otherwise suitably formed for connection with a hose. The
screw g is by preference formed with a flange let into the body a so as to make a
Bush joint at bottom, and prevented from turning by lugs or pins or bolts or by
other well known means; the nut i is formed with a square to which may be
attached the box spanner for working same. When the nut or valvo i is rnised,
the liquid passes in the direction of the arrows that is to say through the
apertures / into the annular space band to the outlet.

as it is suitably made for small sizes, a is the body, b the annular passage round
the scating. In this case the casing c is cast in one with the body and instead of
the cup leather a simple washer e is shown, being held in position by cover f. The
screw g is screwed into the body and the bottom part jagged for the purpose of
fixing it, and metal is run in all round to form the seating k. The sido
passages hh¹³ may either be cast or drilled. The top of valve or nut i is here
shown with a crutch key but different forms are used for different purposes as for
instance for self closing valves a lover or knob and weight or spring, and for
lavatory uses a wheel or cross may be used. In the case of the bib-cock shown the
inlet is at but it may be reversed if required; the dotted lines show the way
I prefer making the stop-cock and the other forms of this valve may be made into
stop-cocks in the same way.
Figure 8 is a vertical longitudinal section and Figure 9 a side view of another
modification formed with an opening b on one side. The screw g is here shown
cast in one with the body a, and the casing or cover c fixed by means of small
screws or bolts and nuts. The upper part of casing forms a stufling box & and the
top of valve or nut i is by preference formed with a square to which I may attach
any desired means for working the valve; the seating may bo of leather but
metal or other substance may be used.

It will be noticed (as shown in all the figures) that as the lateral openings h_are
slightly raised above the seating the scour of the liquid will keep the seating clear
of any sediment thus avoiding the wear caused by such sediment.
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
First In connection with a valve seating the hollow or tubular part g, screwed
outside and provided with lateral aperture or apertures h in combination with the
valve proper or nut i working thereon, and closed at one end where it passos out
through the body, substantially as described with reference to the accompanying
drawings.
Second-The combinations of parts forming the improved screw valves or cocks
shewn on the drawings.
