Improvements in Apparatus for Flushing Waterclosets and other
like purposes.
JAMES BOOTH, Manufacturer, of Cheapside Works, Cheapside, Birmingham,
in the County of Warwick, and THOMAS KIRK, Works Manager, of 25 Cook
Street, Nechells, Birmingham, in the County of Warwick do hereby declare the
nature of this invention to be as follows:-
In the construction and arrangement, hereinafter described, of a flushing
apparatus for water closets and other like purposes.
Into a cistern or tank, with sufficient capacity to hold the quantity of water to
be discharged at each flushing operation, we insert a syphon of cast iron or other
metal, the descending leg being of the ordinary tubular shape.
The other, or ascending leg of the said syphon is much larger in diameter than
the descending leg, and is of a tubular segment shape, with a hollow arm on the
side of the tubular segment retainer so as to permit of the reception and working
inside the said tubular segment retainer of a round flap having an arm at the side,
hinged at the end of the said arm, in the interior near the bottom of the hollow arm
of the tubular segment retainer.
A lever, working on slots in top of the cistern or tank, is connected with the said
round flap, by means of a cap with a cranked arm on the one side and a projecting
piece in the centre, the said projecting piece raises the arm of the round flap to the
required height in the tubular segment retainer, the round flap itself working in the
interior of the tubular segment retainer, and the arm of the round flap working
inside the hollow arm at side.
The apparatus is fixed to the tank or cistern by means of the ascending leg of
the syphon being screwed.
The bend of the syphon is a little higher than the top of the tank or cistern, and
above the level of the water.
The action of the apparatus is as follows:-
==
The cistern or tank is supplied by an ordinary ball cock; the chain or cord
attached to the lever being pulled, the round flap, working freely inside the
ascending tubular segment retainer, is suddenly raised upwards, lifting the water
over the bend of the syphon.
The syphon is thereby set in operation, and the water delivered through the
descending leg of the syphon to the water closet or place to be flushed.
The cistern or tank is slowly filled through the ball cock, but the syphon will not
again act until the chain or cord be pulled.
The fact of the round flap, when raised, passing slightly beyond the inlet of the
syphon bend, does not in any way check the flow or offer any obstruction to the
passage of the water.

Improvements in Apparatus for Flushing Waterclosets and other
like purposes.
We, JAMES BOOTH, Manufacturer of Cheapside Works, Cheapside, Birmingham
in the County of Warwick and THOMAS KIRK, Works Manager, of 25 Cook
Street Nechells, Birmingham, in the County of Warwick 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 :-
In the construction and arrangement herein after described, of a flushing
apparatus for water closets and other like purposes.
Into a cistern or tank, with sufficient capacity to hold the quantity of water to
be discharged at each flushing operation, we insert a syphon of cast iron or other
metal, the descending leg being of the ordinary tubular shape.
The other or ascending leg of the said syphon is much larger in diameter than
the descending leg and is of a tubular segment shape with a hollow arm on the
side of the tubular segment retainer so as to permit the reception and working
inside the said tubular segment retainer of a round flap having an arm at the side,
hinged at the end of the said arm, in the interior near the bottom of the hollow arm
of the tubular segment retainer.
A lever, working on slots in top of the cistern or tank, is connected with the said
round flap, by means of a cap with a cranked arm on the one side and a projecting
piece in the centre, the said projecting piece raises the arm of the round flap to the
required height in the tubular segment retainer, the round flap itself working in the
interior of the tubular segment retainer and the arm of the round flap working
inside the hollow arm at side.
The apparatus is fixed to the cistern or tank by means of the descending leg of
the syphon being screwed.
The bend of the syphon is a little higher than the top of the tank or cistern, and
above the level of the water.
The action of the apparatus is as follows:-
The cistern or tank is supplied by an ordinary ball cock, the chain or cord
attached to the lever being pulled, the round flap, working freely in the ascending
tubular segment retainer is suddenly raised upwards, lifting the water over the
bend of the syphon.
The syphon is thereby set in operation, and the water delivered through the
descending leg of the syphon to the water closet or place to be flushed.
The cistern or tank is slowly filled through the ball cock, but the syphon will not
again act until the chain or cord be pulled.
The fact of the round flap, when raised, passing slightly beyond the inlet of the
syphon bend, does not in any way check the flow or offer any obstruction to the
passage of the water.
We will now prcceed to describe with reference to the accompanying drawings
the manner in which our invention is to be performed.
(Fig. 1.) represents a longitudinal section; and Fig. 2 the plan of flushing
apparatus for water closets and other like places; the parts of the said flushing
apparatus being constructed and combined according to our invention.
In the said Fig. 1 & 2. the cistern or tank is represented filled with water to the
proper level, by the action of an ordinary ball cock, and the apparatus is ready for
the flushing operation.
Fig. 3. represents a plan of the round flap with an arm, and
Fig. 4. a perspective view of a cap, with a crank on the one side, and a projecting
piece in the centre.
The same letters of reference indicate the same parts in the several figures of
the drawings.

page_text: A. is the cistern or tank, B is the ball cock by which the level of the water in
the cistern or tank is determined; N. is the overflow C. D. is the syphon C being
the ascending leg, and D being the descending leg. The descending leg D is of the
ordinary tubular shape and is connected by means of an ordinary joint to the
delivery pipe passing to the water closet or like place to be flushed.
The ascending leg C. of the syphon is much larger in diameter than the descending
leg D. and is a tubular segment shape as in section (see Fig. 1) and constitutes a
chamber open at bottom but slightly raised from the bottom of the cistern or
tank (A).
The descending leg (D), the ascending leg (C), the hollow arm (G) and the
bend (F) are made in one casting either in iron brass or other metals, and fixed to
the cistern or tank (A) by a single junction at bottom of the descending leg (D);
that is secured by means of the nut (L). In the hollow arm (G.) and the tubular
segment retainer, or ascending leg (C) works a round flap (E) with an arm jointed
at the end of the said hollow arm (G.) by means of a pin (K³) passing through the
cap (M) and the end of the round flap (E).
The round flap with arm (E) is raised in the tubular segment retainer or
ascending leg (C) of the syphon by means of the lever (H) to which is attached a
cord or chain (H¹). (I) being the fulcrum, (K.) is a joint connecting the rod (K2)
with the said lever (H) and further connecting at the opposite end to a stud (K')
which latter is a part of the cap (M).
It will be seen by an examination of (Fig. 1) that the water in the cistern or
tank (A) is at its normal level a little below the bend (F. Fig. 1.) and the flushing
apparatus is inoperative.
When it is required to flush the water closet or other like place to be flushed in
connection with the descending leg (D) the chain or cord (H¹) is pulled down and
with it the lever (H) working on fulcrum (I). This raises the rod (K2) and the
projecting arm on cap (M) (see Fig. 4) suddenly lifts the round flap (E) to the top
of the said tubular segment retainer or ascending leg (C.) without coming in contact
with the sides of the said tubular segment retainer, or ascending leg (C) or the sides
of the said hollow arm (G).
The water is thus lifted over the bend (F) into the descending leg (D) and the
flushing operation is thereby set in action and the water in the cistern or tank (A)
is delivered through the pipe to the closet or place to be flushed.
The cistern or tank (A) is slowly filled by the ball cock (B) and the syphon does
not come again into action until the cistern or tank (A) is filled, and the chain or
cord (H).be again pulled as will be understood from the foregoing description,
reference being had to the accompanying drawings.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
"Improvements in flushing apparatus for water closets and other like places": -
1. The combination of a tubular segment retainer, formed as an ascending leg of
a syphon with a hollow arm at side, as herein before described.
2. The combination of a round flap with arm, working in the interior of the
aforesaid tubular segment retainer, and a cap with a projecting piece underneath
and a crank at the side, as herein before described and illustrated in the
accompanying drawings.
