PROVISIONAL SPECIFICATION.
Certain Improvements in connection with Syphon Flushing Cisterns
and Water Waste Preventers.
We GEORGE BRINDLEY of 50, Alma Street Aston near Birmingham in the
County of Warwick Plumber, JAMES MCEWEN and SAMUEL THOMPSON (trading
as Samuel Thompson & Co.) of Millfields Works near Wolverhampton in the
County of Stafford Ironfounders, do hereby declare the nature of this invention to
be as follows:-
This invention relates to a method by which a rapid syphonic action may be
obtained, whereby the entire contents of the cistern are exhausted at each flushing
without waste of water and our improvements consist in the construction of a
circular or other shaped chamber which stands upon the floor of the cistern or
within a well in same, this chamber is covered in at its top with the exception of a
cone shaped portion which rises a certain height from the covered top and in the
centre of same for the passage of the water.
Immediately over this cone is the syphon composed of two pipes with an elbow
or bend at the top, a bell mouth terminates the pipe and fits over the cone which is
kept a certain and sufficient distance from the sides of same by means of distance
pieces or partitions thereon in order to provide water ways. The second pipe of
the syphon is connected to delivery pipe to closet pan and may be curved or
straight.
Within the circular or other shaped chamber is a loose movable disc of similar
shape having arms, side pieces, or litters, passing and working through the top of
the covered chamber and in connection with suitable lever attachment.
The action is thus. By depressing the lever the loose disc is picked up thus
causing the water in the chamber to be raised and forced through the cone
into the bell mouth of the syphon and up and over the bend thereof thus
displacing the confined air therein and causing a partial vacuum whereby syphonic
action is started which continues until the contents of the cistern become exhausted,
the cistern then refills and the covered chamber is charged by water ways at the
base thereof.
The release of the lever allows the loose disc to descend to its normal position;
but its descent does not affect or check the working of the syphon which once set
in action continues in any case to discharge the contents of the cistern owing to
the water ways being above the covered chamber. This arrangement of covered
chamber and its connections may be used in a cistern either with or without a well
as preferred.

trading as Samuel Thompson & Co. of Millfields Works near Wolverhampton in
the County of Stafford Ironfounders, 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 :-
Our invention relates to a method or methods for syphon flushing cisterns and
water waste preventers for water closets, urinals and the like by which a rapid
syphonic action is obtained whereby the entire contents of the cistern may be
discharged at each flushing and waste of water prevented.

We will proceed to describe fully our improved arrangements with the assistance
of the drawings in which we have illustrated certain methods setting forth the
principle of our invention and the best means we are aware of for carrying the same
into effect.
A is the tank or cistern which is supplied from the main service in the usual
manner by inlet pipe .B. regulated and governed by ball valve and float C. and D.
and having an overflow pipe E. A sunken double well F: extends from the
cistern, this well being preferably of the form shewn vizt. nearly circular at its one
end and elongated with a semi-circular end at the other (though the well or wells
may be made oval square or other suitable shape, the corresponding fittings being
of similar outline) the syphon is composed of two vertical pipes G. G' having an
elbow or bend at the top thereof, the pipe G. which is of a curved form pre-
ferably (or it may be straight) is connected by the screw nut .H. to the usual
delivery pipe I. leading to the closet pan or urinal, the underside of the bend
or top of the syphon rises to the height of the walls of the cistern, the straight
pipe G terminating with a funnel or bell shaped mouth which descends to the top
of the well F. and nearly level therewith. Situated within the circular part of
the well is a circular chamber J. provided with feet or rests and which stands
upon the floor of same, this chamber is covered in at its top with the exception
of a hollow cone shaped extension J¹ which rises a certain height from the
covered top in the centre of same for the passage of the water, the circular
chamber is open at its base to afford water way thereinto.
Rising immediately over the cone J¹ and encircling same is the funnel mouth
of the syphon pipe G which is kept a certain and sufficient distance from the
sides of same by means of distance pieces or partitions K. thereon in order to
provide water ways L. L. between the cone and syphon mouth.
Within the circular chamber is a loose movable disc or lifter M. of similar shape
in plan, having arms, side pieces or lifting rods N. passing and working through.
