Hillmartin Villas, Nightingale Road Wood Green
Middlesex, Engineer do hereby declare the nature of this invention to be as
follows:-
To provide a simple and reliable method of flushing water closets, by means of a
slight movement of the seat when the closet is used.
Sometimes I employ the ordinary double valve cistern, but so arrange the lever
that at rest, the valve in the top compartment is down and that in the bottom
compartment up. To the fulcrum of this lever an arm is attached from which a
rod, chain or other connection descends to the water closet seat.
The seat of the water closet when at rest is in contact with the top of the closet
for only a part of its length measuring from back to front, the other part of the
seat is of a less thickness and there is consequently a space between the lower edge
of this and the water closet equal to the diminished thickness of the seat.
When this part of the seat is depressed, the point where the diminution in
thickness commences acts as a fulcrum and the opposite end of the seat is raised, and
as this part of the seat is in connection with the cistern lever, in this way the top
valve is raised and the lower one let down, thus allowing the water to pass into the
bottom compartment of the cistern.
Whilst the seat is kept in this position the water is retained in the lower com-
partment, but when the seat is permitted to resume its original position the cistern
valves are returned to theirs viz. the top valve down and the bottom valve up
thus discharging the full contents of the lower compartment to flush the water
closet.
The seat is furnished with an axle which rotates in the wall brackets and permits
of its being thrown back when desired. It is also sometimes connected to the
cistern by a chain so that the action of throwing it back, pulls the chain and
reverses the valves, thus causing a flush of water to the closet when it is brought
back to its original position.

Improvements in and connected with the Flushing of Water
Closets.
I SAMUEL JOHNSON of 7 Hillmartin Villas, Nightingale Road, Wood Green
in the County of Middlesex, 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 object of this invention is to provide a simple and reliable method of
flushing water closet pans, by means of a movement of the seat, when the closet
is used.
In carrying out my invention, I may employ a double valve cistern, the lever
carrying the two valves being operated in one direction by a weight, and in the
other direction by the tipping of the seat, which moves a lever in suitable connection
with the valve mechanism

page_text: Means are also provided whereby the seat lever may be operated when the seat
is lifted, and thrown back to admit of slops being thrown into the pan.
In the accompanying drawing:-
Figure 1 is a front elevation of my improved apparatus.
Figure 2 is a side elevation of the same.
Figure 3 is a view shewing the normal position of the seat and its lever.
Figure 4 is a similar view, shewing the position of the parts when the closet is
being used; and,
Figure 5 is a view shewing the operation of the parts when the seat is raised and
thrown back, to permit of slops being thrown into the pan.
A is the pan, which may be of any flush-out systein. B is the seat, which is
pivotted to brackets C extending from the wall, or placed in any other position
convenient to the pan. These brackets may have a forward extension on either
side of the pan to support the seat, or the seat may rest on the rim of the pan.
The pivot pins of the seat work in slots in the brackets, so arranged as to permit
of the back of the seat rising when the front is depressed. The rocking of the seat
takes place on rubber, or other fulcrum pieces a. a, which may be attached to the
underside of the seat, and bear on the rim of the pan, or on the side prolongations
of the brackets. Or, the fulcrum pieces may be formed on the rim of the pan.
The seat B is provided, at back, with cam pieces b, which may be formed in one
with the pivot pins. These cams may be arranged as shewn in the drawing
Figs. 2, 3, and 4, or they may be square or nearly square blocks, as shewn at
Figure 5.
D is a board extending across the back of the seat, and pivotted to the brackets C.
The ends of the board, which I term the seat lever, are provided with forwardly
extending fingers or projections which overlie and rest upon the cam pieces b.
The back of the board or seat lever D is attached by a rod or other connection c
to a double valve arrangement in the flush cistern E.
It will be seen from Figure 4, that when the seat is depressed in front, the seat
lever D will be rocked on its pivots, and will pull on the connection c.
It will be seen from Figure 5, that when the seat is thrown back, the cam pieces b
will act to operate the lever D for the same purpose.
The flush cistern E, will be divided by a partition into two parts, one part being
in connection, by means of the flush pipe d, with the pan A, an opening e of
suitable size in the partition, forming the connection between the two parts of the
cistern.
The double valve mechanism is so arranged, that when in its normal position,
the opening e is closed, and the pipe d is open.
Onto the fulcrum of the valve lever, which extends beyond the side of the
cistern, is fitted an arm, to which the connection c is attached.
One part of cistern E is filled from the main cistern, a bali cock being provided
to cut off the flow as usual.
When the valve arrangement is operated, the e valve is raised and the d valve
lowered, and the water will run from the e part of the cistern, to the d part of the
cistern, and will be retained in the latter.
When the pressure is removed from the seat, the valves will be caused, under
the influence of a weight on the valve lever, to return to their normal position,
viz., e valve closed and d valve open, and the flush will take place.
The same effect will be produced by turning down the seat from the position
shewn at Fig. 5.
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 means herein shewn and described for automatically flushing the pan of
a water closet after use.

page_text: 2. In apparatus for flushing water-closets, the combination of a seat provided
at back with pivots and cam pieces, fulcrum pieces below the seat, a seat lever, a
double valve mechanism in a flush cistern or tank, and a connection between the
lever and the valve mechanism, as set forth.
3. In apparatus for flushing water-closets, the use and application of a seat.
adapted to rock or oscillate on fulcrum pieces below the seat, as and for the purpose
set forth.
