Improvements in the Construction of Valves for Hot and Cold
Water and other Fluids.
We DAVID HANCOCK, DAVID CHARLES HANCOCK, and ALFRED HEARN Hancock,
all of 13 Lett Road, Stratford, in the County of Essex, Plumbers and Gas Fitters do
hereby declare the nature of this invention to be as follows:-
The object of our invention is to construct valves for hot and cold water, and other
fluids which are simple in construction and easy of application, because in the case
for example, of a ball valve made according to our invention and when required to be
applied to cisterns which are close to a ceiling the action is at the top of the valve and
consequently easily accessible, and by turning the valve sideways, the plug can be
taken out at bottom without shifting the arm at all; and further valves constructed
according to our invention are not liable to get out of order, as there is no stuffing
box or packing required to be used.
According to our invention the body of the valve is made in one casting with a
partition therein dividing the valve portion and the valve arm.
The body of valve may be round, oval, angle or other shape and has a slot in the
inside to the top of valve for the working of "disc spindle," which latier may be round,
square, or of any other suitable shape.
Cast on the top of valve are pieces for fixing the arm of ball or other handles. The
disc has a straight spindle or other piece cast on the side with a small flange inside at
the top of socket. At the bottom of socket we screw in a plug which keeps in a piece
of rubber or other suitable material and forms the disc seating, which is easily taken
out for repair.

page_text: At the top of disc spindle we have a slot in which the ball lever passes through for
the opening and shutting of valve or the spindle could be screwed convenient for bib
or other valve fittings.
Between the body and passage for the spindle there is a partition extending below
the valve seating and thereby preventing any water coming up the passage.
The spindle of disc passing through the body of valve to the top and bearing against
the arm head, keeps the disc in a perfectly upright position and presses the leather or
rubber against the seating inside of valve when raised by ball or other appliances,
leaving room between disc and body of valve at bottom for a full flow of water without
any obstruction.

We DAVID HANCOCK, DAVID CHARLES HANCOCK, and ALFRED HEARN HANCOCK
all of 13 Lett Road, Stratford, in the County of Essex, Plumbers, and Gas Fittors 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:
The object of our invention is to construct valves for hot and cold water and other
fluids, which are simple in construction, and easy of application, because in the case
for example, of a ball float valve made according to our invention and when required
to be applied to cisterns which are close to a ceiling, the action is at the top of the
valve and consequently easily accessible, and by turning the valve sideways, the plug
disc can be taken out at bottom without shifting the arm at all; and further, valves
constructed according to our invention are not liable to get out of order, as there is no
stuffing box or packing required to be used.
And in order that our invention may be more fully understood we will proceed to
describe same with reference to the accompanying drawings.
Figure 1 is a vertical section of a valve constructed according to our invention.
Figure 2 is a plan of the same; Figure 3 is an inverted plan, and Figure 4 is an
inverted plan of a valve made according to our invention in which the body of the
valve is made of an angular shape. Figure 5 is an clevation of a similar valve but of
larger size, the disc spindle being semicircular in section.
Similar letters of reference hereinafter used refer to like parts in all the figures.
According to our invention the body a of the valve is made in one casting with a
partition b therein dividing the valve portion and the valve arm.
The body a may be round as at Figures 1, 2 and 3, oval, angular, as at Figuro 4, or
other convenient shape and has a slot or passage c in the inside of the top of valve for
the working of "disc spindle "d' which latter may be round, square, or of semicircular
section as in Figure 5 in which latter case the seat side of the spindle forms a bearing
surface against the ears e.
Cast on the top of the valve are the guiding pieces or ears e to which the arm f of
ball g is jointed, and which guide the disc spindle d¹.
The disc d has a straight spindle or other piece cast on the side and has also a small
flange inside at the top of socket. At the bottom of socket we screw in a plug
which keeps in a piece of rubber or other suitable material h' forming the valve seating,
which is easily taken out for repair.
At top of disc spindle d' we form a slot k through which passes the ball lever f
for the opening and shutting of valve, or the spindle could be screwed for bib or other
valve fittings.
Between the body a and the passage c there is a partition b extending below the
valve seating m thereby preventing any water coming up the passage c.

page_text: The disc spindle d passing through the body a of the valve to the top and bearing
against the arm head e keeps the disc d in a perfectly upright position and presses the
rubber or leather h¹ against the seating inside of valve when raised by ball or other
appliance, thus leaving room when open, between the disc d and body a for a full flow
of water without any obstruction.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
In valves for hot and cold water and other fluids in combination the body a in a
piece with partition b, the slot or passage c and guiding pieces or cars e together with
the disc d with elastic seating, plug h, Hange 1 and disc spindle d¹ substantially as and
for the purposes set forth.
