Improvements in Water Taps or Valves.
I, JAMES HENRY HARRISON, of 5, Warren Street, Stockport, in the County of
Chester, Plumber and Gasfitter, do hereby declare the nature of this invention
to be as follows:-
-
.
This invention relates to improvements in water taps or valves and has for its
objects to render such taps or valves more reliable in action, not liable to leak
whatever the pressure of water may be and easy to repair.
To this end I form a tap or valve casing containing two valves, riz. a ball
valve and a dise valve adapted to operate upon two seatings arranged axially in
line and a suitable distance apart from each other.
The said dise valve is furnished with a washer and has a stem suitably guided
in the tap or valve casing and at its outer end engaged by a screw spindle or by
the float lever in case of a tap or valve for a water supply cistern.
The inner side of the said valve is formed with a projection adapted to pass
through and push the said ball valve off its seating when required to admit water
whilst otherwise the pressure of water in the supply pipe acts direct upon the said
ball and presses same against its seating.
Immediately in front of the said ball valve I form an opening in the tap or
valve casing, furnished with a screw plug which permits of renewing the ball
valve when worn.
The said ball valve seating I form as a part of the casing whilst the dise valve
seating I render removable therefrom so as to be able of renewing the valve
washer when required.
In order to facilitate the regulation of the action of the float lever in case of
a tap or valve for a water supply cistern, I render the float adjustable on its
lever by bending or cranking the free end of such lever and adapting the float to
be lowered or raised thereon by screws or nuts.

and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to improvements in water taps or valves and has for its
objects to render such taps or valves more reliable in action, not liable to leak
whatever the pressure of water may be and easy to repair.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1&2 are longitudinal sections of a water tap or valve constructed in
accordance with my invention, Fig. 1 showing the same as used in connection
with a water supply cistern and Hoat and Fig. 2 as an ordinary tap or valve,
Fig. 3 is an end view of a detail of my improved tap or valve and Fig. 4 a side
view of my improved water tap or valve float.
In carrying out my invention and referring to Figs. 1, 2 & 3, I form a casing a
(preferably made in two parts) arranged to contain two valves, viz. a ball valve b
and a disc valve c adapted to operate upon two seatings d, e respectively, arranged
axially in line and a suitable distance apart from each other.
The ball seating d I form.as part of the casing a whilst the disc valve seating e,
I render removable so as to permit of being renewed when required.
The said disc valve I make in the form of a cup fitted with a washer f and by
a nut g secured upon its stem h which is guided in a bridge i formed on the
seating e, see Fig. 3, and in the outlet end of the casing a through which it
projects.
The inner side of the valve e has a projection & forming an extension of the
stem h, the free end of which is adapted to pass through and push the ball
valve 6 off its seating d when required to admit water whilst otherwise the pres-
sure of water in the supply pipe acts direct upon and forces the said ball valve
against its seating, which relieves the said dise valve from the water pressure
and thus renders same less liable to wear.
Should the pressure of water which often varies be insufficient to hold the ball
valve upon its seating the water will be cut off by the said dise valve and leakage
prevented.
When using my improved construction of tap or valve, as shown in Fig. 1,
for a water supply cistern 7 to be operated upon by a float lever m, I form the
end of the stem h which projects through the casing a, with a slot n and the
outlet end of the casing a with a projection o to which latter I hinge the float
lever m the nose g of which engages in the said slot.
When constructing a water tap or valve for ordinary purposes, as shown in
Fig. 2 I form the stem outside the casing a with a crutch or the like and
on its continuity a thread adapted to engage in a nuts suitably secured to or
formed in the casing a and provided with a stuffing box whereby the disc
valve c can be screwed against or removed from its seating e as may be desired
for the purpose of cutting off or admitting water.
Referring to Fig. 4, in order to facilitate the regulation of the action of the
float lever in case of a tap or valve for a water supply cistern, I render the
float u adjustable on its lever m by bending or cranking the free end of such lever
upwards and adapting the float to be lowered or raised thereon by means of
screw threaded stud secured to the top of the float and made vertically adjust-
able in the end of the float lever m by nuts w applied at each side thereof.
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:
1st. A water tap or valve having two seatings one of which is adapted to receive
a ball and the other a disc shaped valve body, the said ball shaped valve body
being forced against its seating by the water pressure from the main and wamared

page_text: therefrom by the said disc shaped valve body when the latter is removed from its
seating, all substantially as and for the purpose set forth.
2nd. A water tap or valve float lever having its free end bent or cranked and
its float rendered vertically adjustable thereon, all substantially as and for the
purpose set forth.
