therefor for Facilitating Repairs while under Pressure.
I FREDERIC GEORGE SISON HAM of 43 Rockbourne Road, Forest Hill in the
County of Kent, Commercial Traveller do hereby declare the nature of said
invention for "IMPROVEMENTS IN COCKS AND VALVES AND CONNECTING FERRULES
THEREFOR FOR FACILITATING REPAIRS WHILE UNDER PRESSURE to be as
follows:-
وو
This invention is applicable to cocks and valves which are fitted at the end or
outlet of a pipe or to cocks and valves which are not so fitted but where, by reason
of a union being provided or from other reasons the cock can be screwed out or
screwed in a very short distance.
My invention consists in fitting or forming the inlet shank or end of the cock or
valve with a screw thread outside and in forming it with that end closed but
provided with an inlet on one side or with two or more lateral inlets. In
connection with this I form the end of the pipe ferrule into which this screwed
shank is to be inserted with a chambered out part for admitting the water to the
aforesaid lateral hole or holes in the shank. By screwing the shank further in
against a seating formed in the ferrule or by unscrewing it so far that the lateral
hole is covered in the ferrule part, the inlet to the cock or valve, is closed and the
tap or valve can then be repaired under fluid pressure.
of the shank of the cock or valve so as to seat itself fluid tight against a seat
I may thus form the end
formed in the ferrule but while in the normal position it is a short space away from
that seat. I insert a divided washer with or without leather joint washer between
the end of the ferrule and the flange on that side of the cock; by removing this
washer (or it might be two slotted washers) I am enabled to screw the shank in so
far that its end seats itself against the seat in the ferrule. The parts of the
washer may be hinged together and connected by cotter or screw. Or I simply
unscrew the shank so far that the lateral inlet hole is covered in and by the female
part of the ferrule, and in this case I need not face the end of the shank as in the
previous case.

I FREDERIC GEORGE SISON HAM of 43 Rockbourne Road, Forest Hill in the
County of Kent, Commercial Traveller do hereby declare the nature of said
invention for "IMPROVEMENTS IN COCKS AND VALVES AND CONNECTING FERRULES
"and in what
UNDER PRESSURE
THEREFOR FOR FACILITATING REPAIRS WHILE
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
The invention is applicable to cocks and valves of the make known as high
pressure, screw down, loose valve cocks, plug cocks, diaphragm screw down cocks,
or other similar descriptions of cocks or valves also ball valves and range or hot
water cocks or valves and generally to cocks and valves which are fitted at the end
or outlet of a pipe or to cocks and valves which are not so fitted but where by
reason of a union being provided or from other reasons the cock can be screwed out
or in a very short distance.
The object of the invention is to enable the cocks or valves to be repaired
while under pressure such for instance as from the water main or from a supply
cistern.
In the accompanying drawings I have shown my invention applied to several
forms of cocks and valves.
Figure 1 shows the application to an ordinary screw down bib cock or valve.
The shank A is made longer than usual and is screwed with a male screw as usual.
The shank A is constructed with a closed or blank end A¹ and with one or more
lateral inlets B.
In connection with the cock or valve I form the pipe ferrule C, known as a
screw ferrule into which the screwed shank is to be inserted, with a chambered out
part in it as shown. The ferrule or boss C has a female screw inside for a part of
its length and the end of the boss or ferrule is left to solder or connect to lead or
iron or other pipe in the usual way.
The cock or valve being screwed into the ferrule or boss C up to the shoulder of
the cock or valve the water passes through the ports or apertures B freely, being
controlled by the valve or plug used in the cock or valve, but in the event of
repairs becoming necessary through the valve or other parts of the cock or valve
being worn out or leaky, the act of unscrewing the body of the cock or valve a
short distance brings the ports or apertures B forward into the female screwed part
of the ferrule or boss C and presents the closed end A¹ of the shank of the cock or
valve to the water supply in the position shown in Figure 1A thus shutting it off
so effectually that the repairs necessary may be done without inconvenience or loss
of water.
Or I, may as shown at Figure 2 construct the cock or valve in the manner
aforesaid but with the addition of forming the closed or blank end A' of the shank
with a faced metal seating (or a seating of leather or other suitable material) and
forming the ferrule or boss C in the manner aforesaid but with the addition of

page_text: forming at the point marked D a corresponding faced metal seating. I also make
or form a divided washer or distance piece E (with or without leather joint washer)
of metal or other suitable material and hinged and locked or made in two equal or
unequal pieces to connect together to form the distance piece.
This distance piece is fitted round the shank or screwed end of the cock or valve,
and the whole is screwed on to the boss or ferrule.
When necessary to repair the cock or valve I take off the distance piece and then
I am enabled to screw the cock or valve so far into the part C as shown in
Figure 2 that the closed end of the shank of the cock or valve seats itself against
the seating D formed on the boss or ferrule and effectually shuts off the water
supply.
In the case of cocks or valves as shown in Figure 3, having long shanks and
back nuts, as is usual with range and other cocks I form the cock or valve in the
manner aforesaid as shown in Figure 1 with the ports or apertures towards the end
of the shank which has a closed or blank end, and I make the back nut rather
larger than usual.
When necessary to repair the cock or valve the act of unscrewing the body of
the cock or valve brings the ports or apertures under the backnut F and prevents
the flow of water.
I may also construct the ferrule or boss in connection with a cock or valve in
the manner described with reference to Figure 1, but instead of enlarging the
whole of the chamber in the intermediate part of the ferrule I enlarge it only in
one part as shown in the ball cock Figure 4, in which case I continue the female
screw through the part C as far as is necessary and construct a recess in one
portion of the enlarged part, by which means I am enabled to repair the cock or
valve. I effect this by reversing the position of the body of cock or valve or
unscrewing the shank A only so far that the lateral inlet or port in the shank is
covered by the female screw part of the ferrule and the blank or closed end of the
shank is presented to the water supply from main or cistern as before described
whilst the cock or valve is under repair. This mode of construction is also
applicable to stop cocks inserted in a pipe and in connection with a running
socket.
I may also construct the ferrule or boss as shown in Figure 5 in which case the
enlarged chamber C is bent round to form a wall bracket and a union is attached
for connecting a pipe thereto.
Or the ferrule or boss in connection with a cock or valve may be made as shown
in Figure 6, with one or more passages G to lead the water directly to the port or
ports B formed in the screwed shank A of the cock or valve which shank is
constructed with a blank end A¹. By this means I am enabled to shut off the
water from the cock or valve in order to repair the same; I can effect this by
turning the body of cock or valve, so far round that the communication between
the cock or valve, and the passage or passages in the boss or ferrule is closed; or by
turning the boss or ferrule round in a similar way.
I may also use this construction of a male screw A with a blank end A¹ and
having one or more ports B in connection with a ferrule C having one or more
passages G as shown in Figure 6 as a means of closing the communication between
two pipes apart from the use of a stop cock or valve.
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. The construction of cocks and valves and ferrules substantially as
described with reference to Figures 1, 1ª, 3, 4, 5 and 6 with blank or closed cock
inlet shank end and with one or more lateral ports or apertures which may be
closed by unscrewing or slacking back the body of cock or valve from the screwed
ferrule of supply pipe or tank.

page_text: Second. The construction of cocks and valves and ferrules substantially as
described with reference to Figures 2 and 24 with blank or closed cock inlet shank
end, and with one or more lateral ports or apertures which may be closed by
screwing up the shank against a seating on the ferrule of supply pipe or tank.
Third. The construction of connecting ferrules substantially as described and
shown.
