COMPLETE SPECIFICATION.
Improvements in or relating to Flushing Valves.
I, WILLIAM HENRY DOYLE, of 1610, Spruce Street, Philadelphia, in the County
of Philadelphia, State of Pennsylvania, United States of America, Sanitary
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:-
The invention consists in the combination with a water-closet flushing-valve
of a valve for adjusting and cutting off the flow of water to the water-pressure
chamber. It also consists in an air-valve or anti-siphoner for preventing the
flusher from siphoning or sucking back the foul contents of the bowl. And
such other parts as are hereinafter shown.
Reference being had to the accompanying sheet of drawings making part of
this specification, in which
Figure 1 is a longitudinal and diametrical section of the flushing valve or
flusher, on the line 1-1, Fig. 2;
Figure 2 is a diametrical section through the line 2-2, Figure 1;
Figure 3 is a diametrical section through the line 3-3, Figure 1;
Figure 4 is an enlarged longitudinal and diametrical section of a valve to
be applied to the inside of the flusher for preventing siphoning;
Figure 5 is an exterior-view of the upper end of the pressure chamber and
the perforated ring valve for controlling the water pressure; and,
Figure 6 is a plan view of Figure 5.
Similar letters refer to similar parts in the several views.
A is the casing of the flusher consisting in the top and bottom screw ends
or caps, B, C, of the cylindrical shell ]) within which is concentrically fitted
the upper or water-pressure chamber E, the lifting-toe chamber F, and the
bottom valve chamber G, all of which are screwed or otherwise removably
fitted together. From above the chamber E to the valve-chamber G extends a
water way H forming a suitable part of an annular ring or space, Figures 1, 2.
The water-pressure chamber E is provided with a screw-cap I which bears
on a circular or ring-valve J fitted over the reduced end, a, of the chamber,
which is provided with openings, b, aligned with openings, c, in the reduction
or neck, a, so that the communication can be adjusted or cut-off entirely by
sliding the ring on the neck. A valve seat K, and cup leather, d, is located in
the water-pressure cylinder E and has a water pressure or poppet valve L which
is weighted at M and provided with a fluted stem N, operated by a lifting-toe ()
on a shaft P, of a handle Q, dotted lines, bearing against its bottom end e.
R is an intermediate valve which bears on its valve seat f, and is connected
with the top valve L by the stem g, the bottom h, of which has a depending

page_text: screw-shank i, on which screws a conical-nut j, terminating in jaws which
receive a rod S in bottom connection with the slow-closing or cushion-piston T,
of the open-top cylinder U to whose bottom water-pressure is led by means of
a channel, l, leading beneath it and controlled by an inwardly-projecting screw-
plug m which varies the degree of opening in the channel.
Water entering at the top B passes through the aligned openings c, b, of the
neck a, and valve J into the chamber E and pressing on the top of the poppet-
valve L forces it firmly on its seat K, and also its connected valve R is pressed
on its seat f, and the piston T lowered in its cylinder U, by which the How of
water through the flusher in the path indicated by the arrows, is stopped. On
turning the handle Q of the shaft P, the lifting toe operates by lifting the
fluted spindle N and poppet valve L and allows the water to flow from above the
valve L, and said toe by means of its contact with a pin, s, of the stem g, lifts
the valve R to its top limit to reduce the water pressure to a minimum by
draining the water through the valves L, R, into the bottom_ valve
chamber G. The water from the top nozzle B passes down the annular space H
and up under the valve R into the channel V and out to the bowl through the
bottom nozzle C. After flushing the opposite movement of the handle Q closes
the valves L, R, without any concussion their descent being controlled by means
of the water beneath the piston T slowly escaping through its channel 7.
To prevent any siphoning of the foul matter of the seat-bowl into the flusher
an exterior air-pressure is automatically applied to the interior of the flusher
through the medium of a valve which while admitting the air-pressure at the
same time prevents the water of the flusher from discharging through the valve
to the outside. In this instance the valve consists in a pipe or cylinder W
Figure 4 suspended from the inside of flusher casing A by its conducting
nozzle n.
Its bottom end has a screw-cap o, which is provided with an out-
wardly opening flap-valve p. The upper end has upwardly projecting supports q,
which support a ball-valve X over the top end of the cylinder W without
closing it, while above is the ball-valve seat r. The air pressure for preventing
siphoning enters the nozzle n, and passes down the cylinder W through the
valve 2, which is normally open until the rising of the water of the flusher
reaches said valve 2, and closes it. The ball-valve X operates ancillary to the
flap valve 2, in case its closing should be hindered. I do not limit myself to
the particular valve illustrated and described but propose to use any form of
valve which will carry into effect an exterior air-pressure applied to the interior
of a flusher or water-closet valve for preventing siphoning from the bowl to
the flusher.
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 with a flusher, of a valve fixed within the flusher by
which an exterior pressure is applied to the interior of said flusher for pre-
venting siphoning from the bowl to said flusher.
2. The combination with a flusher, of an interior water-pressure chamber, a
circular valve seat of the water pressure chamber, a ring valve, and aligned
openings or ports of the water-pressure chamber and ring valve for regulating
a water pressure on the valve of the water-pressure chamber.
3. The combination with a flusher, of a flusher casing, a lifting-toe chamber,
a slow-closing or water-pressure chamber, a slow-closing or water-pressure valve,
a valve with a fluted stem, and a vibrating toe, in flushing a water-closet bowl.
4. The combination with a flusher of a flusher casing, a lifting-toe chamber,
a slow-closing or water-pressure chamber, a slow-closing poppet or water-
pressure valve, a water-cushion piston cylinder at the bottom of the flusher-
casing, a water-cushion piston, connection between the slow-closing or water

page_text: pressure valve and the water-cushion piston, and a vibrating toe, in flushing a
water-closet bowl.
5. The complete flusher substantially as described and illustrated in the
accompanying drawings.
