"IMPROVEMENTS
IN APPARATUS FOR REGULATING THE SUPPLY OF WATER TO WATER CLOSETS,
URINALS, AND OTHER PLACES, AND PREVENTING WASTE."
My Invention relates to improved apparatus for supplying measured quantities
of water to water closets, urinals, lavatories, or other places, and preventing waste.
The apparatus consists of an oscillating receiver, which is so pivoted as to be
tilted by the weight of the water contained in it. This receiver is placed within a
tank, and is supplied through a ball. valve. The receiver works on a pivot beneath
it in such position as to ensure the preponderance of weight in the direction of the
outlet from the tank, and the receiver is hopper shaped, so as to discharge its
contents quickly when tilted. The receiver is held up by a catch on a lever, which
by the same movement that releases the receiver also holds the ball valve shut
whilst the receiver is being discharged.
The receiver is counterbalanced or acted on by a weighted lever to return it to
position after being discharged, and may be provided with a float which when the
receiver is tilted is immersed in the after-charge to assist the counterbalance in
righting the receiver.
Instead of the receiver being kept filled, it may be so arranged as to remain
empty, and only be filled at the time of actual use, so as to avoid all damage from
frost when placed in exposed positions. In this case the receiver, instead of being
normally held up by a catch, remains in the tilted position, and its rear edge taking
under the ball arm holds it up and keeps the valve closed. The chain or other
connection is in this case attached directly to the receiver, and on pulling it the
receiver is immediately caused to right itself, thereby lowering the ball arm, and
opening the valve to fill the receiver, which not being held, is tilted by the weight
of the water as soon as it has filled sufficiently.
The apparatus is simple in construction, inexpensive, and not liable to get out of
order as only one valve, and that the ordinary ball valve, is used.

LEWIS WALL, of Islington, in the County of Middlesex. " IMPROVEMENTS
IN APPARATUS FOR REGULATING THE SUPPLY OF WATER TO WATERCLOSETS,
URINALS, AND OTHER PLACES, AND PREVENTING WASTE."
My Invention relates to improved apparatus for supplying measured quantities
of water to waterclosets, urinals, lavatories, and other places, and preventing
waste.
The apparatus consists of an oscillating receiver, capable of being tilted only by
the weight of the water contained in it when filled to a certain height, said
receiver being placed within a tank and supplied through a ball valve. The
receiver works on a pivot beneath it in such position as to ensure the preponderance
of the weight in the direction of the discharge pipe, and the receiver is hopper
shaped, so as to discharge its contents quickly when tilted. The receiver is held up
by a catch on a lever, from which it can be released by pulling the ordinary handle.
The receiver is thereupon tilted by the weight of water within it, and during this
movement it holds the ball valve shut.
The catch lever is weighted and acts on the receiver to return it to position after
being discharged, and the receiver would be counterbalanced to hold the receiver
upright until filled to a certain height, and to assist the weighted lever in
righting it.
Instead of the receiver being kept filled, it may remain empty, and only be filled
at the time of actual use, so as to avoid all damage from frost when placed in
exposed positions. In this case the receiver remains in the tilted position, and its
rear edge taking under the ball arm, as in the former case, bolds it up and keeps
the valve closed. The chain or other connection from the lift up handle is in this
case attached directly to the receiver, so that on pulling it the receiver will be
immediately caused to right itself, thereby lowering the ball arm and opening the
valve to fill the receiver, which, not being held by any catch, tilts as soon as it is
sufficiently full for the weight of the water to preponderate on the discharge side.
The apparatus is simple in construction, inexpensive, and not liable to get out of
order, as only one valve, and that the ordinary ball valve, is used.
DESCRIPTION OF DRAWINGS.
Figure 1 is a longitudinal section of the first mentioned arrangement in which
the receiver is normally kept filled; Figure 2 shows the same apparatus, the
receiver being represented it its tilted position.
A is the tank, and B is the hopper shaped self tilting receiver mounted on a
horizontal axis C beneath it, resting in bearings c on the bottom of the tank; D is
the weighted lever, and E, the catch by which the receiver is held upright; Fis

and open the valve to refill the receiver; H is a counterweight on the back of the
receiver attached adjustably to enable the quantity of water which the receiver
must contain before tilting to be regulated. The receiver is made of the hopper
like form shown, so that when filled with water to the level at which the valve is
shut off by the ball float it will tilt and discharge itself suddenly. The whole of a
given quantity is thus discharged at once, and neither more nor less, and a good
flush ensured. The tank A is provided with a small chamber to contain the after
charge separated from the discharge pipe by a perforated partition a; a¹ is a
rubber stop on the bottom of the tank on which the receiver rests when upright.
Figures 3 and 4 illustrate the other arrangement in which the receiver is
normally kept tilted and empty, as shown in Figure 3, and temporarily raised to
the position Figure 4 for the purpose of being filled. The same letters of reference
indicate the same parts which need not be again described.
In this case the weighted arm D and latch E are dispensed with, and the cord or
chain G is led over a pulley g and attached directly to the receiver B, as shown,
and connected to the pull handle or to a self acting closet seat.
Having described the nature of my Invention, and the manner of performing the
same, I declare that what I claim as the Invention to be protected by the herein-
before in part recited Letters Patent is,-
1st. The apparatus for supplying measured quantities of water and preventing
waste, consisting of a hopper-like self-tilting receiver contained within a tank, and
discharging its contents bodily thereinto, a weighted catch lever to retain and right
it, and a ball valve, all combined to operate substantially as herein described and
shown in Figures 1 and 2 of the Drawings.
2nd. A hopper-like self-tilting receiver contained within a tank and discharging
its contents bodily thereinto, provided with means for righting it for the purpose
of filling, and combined to operate in connection with a ball valve, substantially as
herein described and shown in Figures 3 and 4 of the Drawings.
In witness whereof, I, the said Lewis Wall, have hereunto set my hand and
seal, this Fourteenth day of October, in the year of our Lord One thousand
eight hundred and eighty-one.
LEWIS WALL. (L.S.)
