IY IDIONAL DI BUITIVATION.
Improvements in Outlet Valves for Sewer Flushing Tanks and
other Purposes.
BRIERLEY DENHAM HEALEY of Bamber Bridge, in the County of Lancaster,
Civil Engineer do hereby declare the nature of this invention to be as follows :-
My present invention refers to valves for tanks in which water is stored in quantities
of from one thousand to two thousand gallons, which water when passed through the
outlet valve is used for flushing sewers.
According to my present invention the outlet valve has a ring flange bolted under
the bottom of tank with or without a bridge for carrying a centrally fixed cap, and is
jointed to tank bottoin with an india rubber washer broad enough to serve as the
seating for valve sleeve which latter moves vertically in opening. Between the valve
sleeve and the fixed cap is an india rubber roller ring, slightly compressed to form the
packing of upper seat of valve, but free to roll as the valve rises or falls. When the
ring flange is made without a bridge, a substitute is provided above the valve within
the tank, from which the fixed cap is then suspended.
In connection with the levers and rods for actuating the valve a quadrant is pro-
vided which is graduated so as to allow of valve being opened to suit various sizes of
sewers.
It is obvious that the valve may be used for other purposes.

Improvements in Outlet Valves for Sewer Flushing Tanks and
other Purposes.
I, BRIERLEY DENHAM HEALEY, of Bamber Bridge, in the County of Lancaster,
Civil Engineer, 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 :-
My present invention refers to valves for wheeled tanks, in which water is stored in
quantities of from one thousand to two thousand gallons, which water when passed
through the outlet valve is used for flushing sewers.
The outlet valve has a ring flange bolted under the bottom of tank with or without
a bridge for carrying a centrally fixed cap, and is jointed to tank bottom with an
india rubber washer broad enough to serve as the seating for valve sleeve, which
latter moves vertically in opening.
Between the valve sleeve and the fixed cap is an india rubber roller ring, slightly
compressed to form the packing of upper seat of valve, but free to roll as the valve
rises or falls. When the ring flange is made without a bridge, a substitute is provided
above the valve within the tank, from which the fixed cap is then suspended.
In connection with the levers and rods for actuating the valve, a quadrant is pro-
vided which is graduated so as to allow of valve being opened to suit various sizes of
sewers. It is obvious the valve may be used for other purposes.
And in order that this invention may be better understood I will describe it with
reference to the accompanying drawing.
1 is the outlet flange, 2 the tank bottom, 3 the bridge in outlet, 4 the fixed central
cap, 5 india rubber joint and seat, 6 the valve sleeve, 7 the india rubber roller ring,
7 indicates the position of roller ring when valve is open, 8 shews 'recess inside of
sleeve for handiness in putting on the roller ring, 9 is the graduated arm or quadrant,
10 the lever which operates the valve, 11 slot in lever for guiding the quadrant.
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
1. The combination and use of an annular sleeve with one edge resting on a rubber
seat, having a centrally fixed cap between which and the sleeve there is a roller ring.
2. The combination of a quadrant in slotted lever the end of quadrant forming a
wedge for keeping valve shut.
