Improvements in Automatic or Self Acting Water Waste Preventing
Valves.
I, WILLIAM Ross Junior residing at Number two Golfhill Terrace, Dennistoun,
Glasgow, in the County of Lanark, Draughtsman do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in automatic or self acting water wasto
preventing Valves for supplying, and regulating the supply of water to closets,
urinals &c. The waste preventing Valve is enclosed in a cylindrical Vessel or casing
which is closed at the bottom end, and fitted with a moveable cover at the top end.
At a certain distance above the bottom of this Vessel, is a false bottom having a hole
in the centre thereof into which is fixed the Valve seating. The Cylindrical Vessel or
casing is provided with an inlet branch above the Valve seating, and an outlet branch
below the Valve seating, each branch being provided with a coupling for completing
connections. The Valve may either be a simple disc raised from its seat by a sucker,
which is attached to a Valve cover and spindle, or may form the sucker and Valve
combined. The Valve cover is fixed to the lower end of the spindle, either with or
without the sucker attached, and above the valve cover a thrust plate is also attached
to the spindle. The upper end of the spindle projects through a gland in the moveable
cover of the cylindrical Vessel or casing. When at rest the valve cover is suspended
above the Valve, by a spiral spring, which is compressed between the false bottom of
the cylindrical Vessel or casing, and the thrust plate. The said spring supports the
Valve cover, and prevents its connection with the Valve until the spring is further
compressed by a force, applied to the projecting end of the spindle. "A force so
applied brings the Valve cover into contact with the Valve, thus compressing the
sucker. On the force being removed the spring is allowed to expand, thus raising
the Valve by the power of suction. When equilibrium is restored within the cavity
of the sucker the Valve drops away from the Valvo cover, and shuts off the flow of
water through the Valve Seating, thus regulating the supply, and preventing waste
of water.

Valves.
I, WILLIAM Ross Junior, sometime residing at Number two Golfhill Terrace,
Dennistoun, Glasgow, now at Number One hundred and thirty four Ingleby Drive,
Dennistoun, Glasgow, Draughtsman, 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 :-
This invention relates to improvements in automatic or self acting water waste
preventing Valves for supplying and regulating the supply of water to closets,
urinals &c. The waste preventing Valve is enclosed in a cylindrical Vessel or
casing C, which is closed at the bottom end, and fitted with a moveable cover at the
top end.
At a certain distance above the bottom of this Vessel is a false bottom F. B.
having a hole in the centre thereof, into which is fixed the Valve seating V. S. The
cylindrical Vessel or casing (is provided with an inlet branch I above the Valve
seating, and an outlet branch O below the Valve seating, each branch being provided
with a coupling for completing connections. The Valve V may either be a simple
disc raised from its seat by a sucker, which is attached to a Valve cover, and spindle,
or may form the sucker and Valve combined as shown in the annexed drawing the
flexible rim S¹ of the Valve forming the sucker. The Valve cover V. C. is fixed to
the lower end of the spindle S either with or without the sucker attached, and above
the Valve Cover V. C. a thrust plate T. P. is also attached to the spindle. The upper
end A of the spindle S projects through a gland in the moveable cover of the
Cylindrical Vessel or Casing . When at rest the Valve cover V. C. is suspended
above the Valve V, by a spiral spring S. P. which is compressed between the false
bottom F. B. of the cylindrical Vessel or casing C, and the thrust plate T. P. The
said spring S. P. supports the Valve cover V. C. and prevents its connection with
the Valve V, until the spring S. P. is further compressed by a force applied to the
projecting end A of the spindle. A force so applied brings the Valve cover V. C.
into contact with the Valve V, thus compressing the sucker S¹. On the force being
removed the spring S. P. is allowed to expand, thus raising the Valve V by the power
of suction. When equilibrium is restored within the cavity of the sucker, the Valve V
drops away from the Valve cover V. C. and shuts off the flow of water through the
Valve seating V. S, thus regulating the supply, and preventing waste of water. The
quantity of water is increased or diminished as desired, by a regulating screw R. S.
Instead of the internal spiral spring mentioned above a lever and weight may be
applied externally, for lifting the Valve.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The application of a suction Valve as described above to self acting water closets
and urinals, as shown in the annexed drawing.
2. A Suction Valve enclosed in a cylinder or Vessel and actuated by direct
pressure on the spindle substantially as herein described, or any colourable imitation
thereof.
