PROVISIONAL SPECIFICATION.
Improvements in and connected with Flushing Apparatus for
Water Closets.
I, WESLEY BRIGGS, of 7 and 11 Sheepscar Street, and Gipton both in the City
of Leeds, Plumber and Sanitary Engineer, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to provide improved flushing apparatus for water
closets, which will lift the water noiselessly to cause the flush.
According to my invention the apparatus consists of a cylinder (fixed within the
cistern) fitted with a perforated plate and diaphragm carried on a rod which passes
out through the top of the said cylinder, and through a tube fixed in the said top,
which is made air tight so as to form an air valve by means of a rubber or other
such washer or covering upon the said tube, so that when the said rod is lifted a
plate or disc carried on the said rod comes in contact with the end of the said tube
and washer and excludes air from the syphon until the water is finished. When
the said rod is lifted the water charges the syphon and water flows in under the
diaphragm (through holes in the said cylinder case) giving a full discharge from the
cistern.
When the cistern has been emptied the rod and piston or perforated plate and
diaphragm return to their normal positions, and the plate or disc carried on the
rod is moved away from the valve so admitting air through it into the cylinder, and
stopping any further syphonage until charged again.
The top of the cylinder provided with unions to which a pipe is connected.

Improvements in and connected with Flushing Apparatus for

I, WESLEY BRIGGS, of 7 and 11 Sheepscar Street, and Gipton, both in the
City of Leeds, Plumber and 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 object of this invention is to provide improved flushing apparatus for water-
closets, which will lift the water noiselessly to cause the flush.
DESCRIPTION OF
DRAWINGS
Fig. 1, is a sectional clevation of my invention.
Fig. 2, is a plan of Fig. 1.
According to my invention the apparatus consists of a cylinder A (fixed within
the cistern B). This cylinder is provided with holes A', and fitted with a
perforated plate C and diaphragm D (preferably of rubber) carried on a rod E,
which passes out through the top F of the said cylinder A, and through a tube G

page_text: fixed in the said top F, which is made air tight, as hereinafter explained, so as to
form an air valve by means of a rubber or other such washer or covering H upon
the said tube G, so that when the said rod E is lifted a plate or disc J carried on
the said rod comes in contact with the end of the said tube G and washer H, and
excludes air (otherwise free to come through the tube G) from the syphon K, until
the water is finished.
L is a regulation tube joined into the syphon K to control the quantity of water
to be allowed for the flush, which is done by shortening or lengthening the distance
between the bottom of the cistern B and the end of the pipe L.
The cistern B is filled through pipe connected to union M, to which the ball tap
or cock valve N is connected, the supply is shut off by the action of the ball O as
ordinary. P is the pipe to the closet basin.
The rod E is connected to a link or loop F¹ joined to a lever F2 pivotted at F
upon the cistern B.
To this lever the hand chain for giving the flush is connected.
When the cistern B is charged water is also within the cylinder A into which it
passes through the holes A¹.
When it is desired to make the flush the rod E is lifted (through the lever F²
and hand chain,) so bringing the disc or plate J into contact with the end of the
tube G and washer H, which excludes the admission of air through the tube G
into the cylinder A. As soon as the rod E is lifted, as aforesaid, the water, already
in the cylinder A, charges the syphon K, and water continues to flow into the
cylinder A through the holes A', water is also drawn up the tube L by the suction
created in the said pipe by the passage of the water through the syphon K from the
cylinder A, the water continues to flow until a full discharge from the cistern is
effected, and this is regulated by the tube L, for as soon as the level of the water
in the cistern B gets below the end or level of the tube L, air rushes into the said
tube and stops the syphonage, so that by regulating the distance of the end of the
tube L from the bottom of the cistern B the amount of water to be allowed for the
flush can be regulated.
When the cistern B has been emptied the rod E, piston or perforated_plate C,
and diaphragm D return to their normal positions, and the plate or disc J carried
on the rod E is moved away from the valve or tube G and washer H, so admitting
air through it into the cylinder A, and stopping any further syphonage, until charged
again.
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 :-
upon
1. A flushing apparatus, for water-closets, having a cylinder A within a cistern B,
and a syphon K leading from the said cylinder to the closet basin, the said cylinder
being fitted with a perforated plate C, a diaphragm D, and a disc or plate
a rod E, which passes through a tube G, upon which is an elastic washer or
covering H, so that on the lifting of the rod E until the disc or plate J comes in
contact with the end of the tube G, and washer or covering H, air is excluded from
the said cylinder, and water caused to pass through the said syphou to give the
flush, substantially as shown and described.
2. A flushing apparatus, for water-closets, having a cylinder A within a cistern B
and a syphon K, leading from the said cylinder to the closet basin, the said cylinder
being fitted with a perforated plate C, a diaphragm D, and a disc or plate J upon a
rod E which passes through a tube G, upon which is an elastic washer or
covering H, so that on the lifting of the rod E, until the disc J comes in contact
with the end of the tube G and washer or covering H, air is excluded from the
said cylinder A, and water caused to pass through the said syphon K to give
the flush, and a regulating tube L for admitting air into the syphon K to stop the
flush, substantially as shown and described.

page_text: 3. In flushing apparatus for water-closets, the combination with the cistern B of
a cylinder A. having holes A' a perforated plate C, a diaphragm D, a disc or plate J
upon a rod E, which passes through a tube G and washer or covering H; a
syphon K joined to the said cylinder A and to a pipe P leading to the closet
basin, with a tube L, substantially as and for the purposes shown and described.
Dated this 14th day of November 1894.
