I, RICHARD BROWN EVERED, of 28 Drury Lane, in the County of Middlesex,
Brass Founder, do hereby declare the nature of my invention for "IMPROVEMENTS
IN FLUSHING APPARATUS CHIEFLY DESIGNED FOR URINALS AND WATER-CLOSETS
"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to flushing apparatus chiefly designed for urinals. and
water-closets.
The object of my said invention is to provide for the opening of the supply valve
of a flushing tank and the closing of the discharge valve thereof by the depression
of a pivotted plate or seat, and for the automatic opening of the discharge valve
and closing of the supply valve when the said plate or seat is released.
My invention is illustrated in the accompanying drawing, in which
Figure 1 is a perspective view of a urinal provided with my improved flushing
apparatus.
Figure 2 is a vertical central section of the same, drawn to an enlarged scale.
Figure 3 is a vertical longitudinal central section, drawn to an enlarged scale,
showing the supply valve of the flushing tank.
Like letters indicate corresponding parts in all the figures.
a indicates the basin or receptacle of the urinal, which is connected by a pipe a¹
with a drain or sewer.
6 is the flushing tank, which has a discharge pipe c extending therefrom to the
top of the basin or receptacle a; d is the valve-cock for the supply of water to
the said tank, and s is the discharge valve, which is provided with a spindle e¹.
f is a metal plate pivotted at f¹ to a base-plate f and supported upon two buffers
or cushions g of india-rubber or other suitable material. This plate is so arranged
that à person must stand thereon in order to use the urinal. It is preferably
perforated as shown, to form a grating. h is a lever which is pivotted at h¹ and
has a weight i attached to one of its extremities, so that its other extremity is
pressed upwards against the underside of the plate f. k is a bent lever pivotted
at k. One arm of this lever is provided with a weight and the extremity of the
said arm rests upon the lever h. The other arm of the lever k is coupled to the
73 .

page_text: lower end of a rod or link . This rod or link is coupled at its upper end to
a lever m pivotted at m¹ to a bracket n attached to, or forming part of, the shell
of the valve-cock d.
The valve-cock & is shown in Figure 3. Its valve d' is provided with a spindle d
which projects upwards and is furnished with a push-knob d³, fitted to slide in
a recess or cavity in the top of the shell of the cock. A spring d is arranged
within the said recess or cavity and tends to keep the valve d closed and to press
the push-knob d³ against the underside of the lever m. The said spring, therefore,
tends to raise the said lever and the link 1, and, to some extent, assists in retaining
the plate fin its highest position, or in returning it to this position after it has
been depressed as hereinafter described.
The rod or link is made with a slot through which extends the supply pipe o
A lever p is pivotted at p¹ to a bracket q attached to, or forming part of, the tank b.
This lever extends at p through a slot in the rod or link . The spindle e¹ of the
discharge valve e is coupled at p³ to the lever p.
r is a pipe which is connected at one end to the tank 6 near the top thereof, and
at the other end to the pipe c beneath the valve e, and which permits any surplus
water that may be admitted into the said tank to overflow into the basin or
receptacle a The overflow may, however, be provided for in any other convenient
manner.
The operation of the apparatus is as follows, that is to say:-When a person
stands upon the plate f, his weight causes the compression of the buffers or cushions g
and of the spring d in the cock d, and, by means of the rod or link and levers m, p,
closes the discharge valves and opens the supply valve d' so that water flows into
the tank b. When the plate f is released, the buffers or cushions g and the spring d
by their reaction, raise the plate f, close the supply valve d¹, and open the discharge
valve e, so that the water which has accumulated in the tank 6 flows down. the
pipe c and flushes the basin or receptacle a.
With a flushing apparatus constructed as above described, the flushing of the pan
or receptacle, after being used, is ensured.
The raising of the plate f and the operation of the valves, by the reaction of the
said buffers or cushions and spring, is, to some extent, assisted by the weights i, i¹.
It is obvious that the flushing apparatus above described can be adapted for use
with a water-closet by connecting the rod or link with a pivotted seat instead of
with the plate f.
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. A flushing apparatus wherein the supply and discharge valves, are con-
nected, by suitable mechanism, with a pivotted plate or seat in such a manner that,
when the said plate or seat is depressed, water will be supplied to the flushing
tank, and, when the plate or seat, is released, the water will be discharged from the
said tank, as, and for the purposes, specified.
Second. The improved apparatus consisting of the parts constructed and com-
bined substantially as described with reference to the accompanying drawing and
operating as, and for the purpose, specified.
