Especially Adapted for High Pressure Water Main
Supply.
I, EDWIN CHARLES URRY, "Engineer" of 52 Lambton Road, Hornsey Rise, N,
in the County of Middlesex, do hereby declare the nature of my Invention for
"IMPROVEMENTS IN BALL VALVES (EQUILIBRIUM OR OTHERWISE) ESPECIALLY
ADAPTED FOR HIGH PRESSURE WATER MAIN SUPPLY".to be as follows:-
My Invention relates to improvements in valves as used for supplying cisterns,
boilers and the like with water.
In carrying my Invention into practice, I so construct the body of my improved
valve, so as to use it in combination with a tube working in a vertical position in
the said body. This tube, is fixed to, and passes through the ball or other
hollow vessel.
Through the said tube the water is supplied, and shut off direct from the main,
when coming in contact with a rubber, leather, or other suitable elastic washer
fixed in the top of body before described, forming the seat (or may be constructed
metal to metal) on the water attaining its required level. The said body is cast
with a division at its centre, below the said division the supply tube has a flange
of such dimensions which places the valve in equilibrium, thus ensuring an effec-
tive and easy closing valve under high pressures. I also construct the ball with a
bottom of a slightly concave form.

I, EDWIN CHARLES URRY, of 52 Lambton Road, Hornsey Rise, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention for "IMPROVE-
MENTS IN BALL-VALVES (EQUILIBRIUM OR OTHERWISE) ESPECIALLY ADAPTED FOR
HIGH PRESSURE WATER MAIN SUPPLY" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying drawings forming a part of
this Specification:-
My invention relates to improvements in valves for use in connection with
pipes for supplying cisterns, boilers and the like, such valves being commonly
known as ball-valves.

The said invention is illustrated in the accompanying drawings in which―
Figure 1 is a plan or top view of a valve constructed in accordance with my
invention and
Figure 2 is a vertical section of the same.
Figure 3 is an elevation of the valve chamber proper and
Figure 4 is a horizontal section of the same.
The remaining Figures are hereinafter described, and like letters indicate the
same parts throughout the drawing.
In carrying my invention into practice I employ a body or chamber a with
which I combine a tube b which passes downward through and is connected to the
ball or float c as shewn. Through this tube the water entering the valve chamber
at & from the main is designed to flow until the said tube is raised by the action of
the water in the cistern or other receptacle to be filled, upon the float c when such
water reaches a predetermined level. In the interior of the valve chamber or
body a I cast a series of small wings e which serve to guide the tube b in its
vertical movements. Above the top of this tube I arrange a washer f of leather
india-rubber or other elastic material secured in the valve body a. Against this
washer the upper end of the tube b is forced so as to effectually cut off the supply
from the main when the float c is raised when the water in the receptacle to be
filled attains the desired level. g represents a division or partition in the valve
body a to prevent the pressure in the main acting upon a flange or collar h on the
tube b which collar is arranged in the lower portion of such body a as shewn and
serves to place the valve in equilibrium thus ensuring the easy closing of the same
when subjected to high pressures. i represents a leather washer which serves to
prevent the escape of water from the main when the valve is closed by reason of
its upper end coming in contact with the washer f.
Figure 5 is a vertical section and Figure 6 a horizontal section shewing a slight
modification in the construction of my improved valve wherin I employ in place
of the wings e and partition g previously described, a conical partition e¹ which
supports the tube b at or near its top, thus ensuring a free vertical movement of
the said tube, against the pressure of the water from the main.

page_text: Figure 7 is a similar view to Figure 5 the only modification being that instead
of employing a washer i as illustrated in Figures 1 and 5, I make use of a ring i¹
of india-rubber or other suitable material.
Figure 8 is a vertical section and Figure 9 a horizontal section shewing the
adaptability of my invention to a valve which is designed to be controlled as to its
movements by an ordinary lever carrying a ball at its end. It will be seen by
reference to these Figures that the arrangement is substantially the same as that
described in previous Figures of the drawing, the only modification being that the
tube b is in this case provided with a valve or seat at its upper end and is provided
with apertures 61 through which the water flows into and through the bore of the
tube when such valve is withdrawn from its seat by the fall of the level of the
water in the cistern or other receptacle.
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 a valve such as is herein referred to, the tube b (through which the
water is designed to flow and which is connected with the ball or float c) in
combination with the valve body a having the washer f substantially as herein set
forth and for the purposes specified.
Second. A valve for supply pipes or mains consisting of the parts constructed
combined & operating substantially as herein set forth and shewn in the drawing.
