Improvements in Apparatus for Flushing Water Closets and other
iike purposes.
OSCAR CRANE, of Crane Brothers, Manufacturers, of 183, Moseley Street, Bir-
mingham, in the County of Warwick, do hereby declare the nature of this in-
vention to be as follows:
My invention has for its object to affect the flushing of water closets and other
like places by a simple and inexpensive apparatus not liable to get out of order.
Into a cistern or tank with sufficient capacity to hold the quantity of water
to be discharged at each flushing operation, I insert or cast in the cistern or
tank a straight pipe and well. The straight pipe is as high as the top of the
said cistern or tank. And when the said straight pipe is not cast in the said
cistern or tank it is connected therewith by a single screw junction. The said
well is part of the said cistern or tank. In making a flushing apparatus accord-
ing to my invention I form preferably of cast iron and in a single casting a

or ascending leg of the said syphon as a conical shape and is much larger in
diameter than the descending leg and works freely in the said well in the cis-
tern or tank and the ascending leg works freely over the said straight pipe. A
lever working in slots in top of cistern or tank is connected with the said syphon
at top by means of a hook that is cast on the said syphon and a bend or hook on
the one end of lever.
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
syphon is raised upwards and the said syphon being sufficiently heavy wher
liberated suddenly raises the water which is in the well upwards and over the
bend of the syphon. The syphon is thereby set in operation and the water to
be flushed is delivered through the descending leg and straight pipe to the water
closet or place to be flushed,
The cistern or tank is slowly filled again by the ball cock but the syphon will
not again act untill the cistern or tank is filled and the operating chain or cord
is pulled and liberated.

OSCAR CRANE, of Crane Brothers, Manufacturers, of 183, Moseley Street, Bir-
mingham, in the County of Warwick, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
;--
My invention has for its object to affect the flushing of water closets and other
like places by a simple and inexpensive apparatus not liable to get out of order.
Into a cistern or tank with sufficient capacity to hold the quantity of water
to be discharged at each flushing operation. I insert or cast in the cistern or
tank a straight pipe and well. The straight pipe is as high as the top of the
said cistern or tank. And when the said straight pipe is not cast in the said
cistern or tank it is connected therewith by a single screw junction.
The said well is part of the said cistern or tank. In making a flushing apparatus
according to my invention I form preferably of cast iron and in a single casting a
syphon. The descending leg of which is the ordinary tubular shape. The other
or ascending leg of the said syphon has a conical shape and is much larger in
diameter than the descending leg and works freely in the said well in the cis-
tern or tank and the descending leg works freely over the said straight pipe. A
lever working in slots in top of cistern or tank is connected with the said syphon
at top by means of a hook that is cast on the said syphon and a bend or hook on
the one end of lever.
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
syphon is raised upwards and the said syphon being sufficiently heavy when
liberated suddenly raises the water which is in the well upwards and over the
bend of the syphon, The syphon is thereby set in operation and the water to
be flushed is delivered through the descending leg and straight pipe to the water
closet or place to be flushed,
The cistern or tank is slowly filled again by the ballcock but the syphon will
not again act until the cistern or tank is filled and the chain or cord is pulled
and liberated.
I will now proceed to describe with reference to the accompanying drawings
the manner in which my invention is to be performed.
Figure 1 represents in longitudinal section of a cistern or tank of flushing
apparatus for water closets and other like places being constructed and combined
according to my invention.
Figure 2 represents a plan.
The same letters of reference indicate the same parts in the several figures of
the accompanying drawings a is the cistern or tank a is the overflow c, b is the
syphon is the descending leg and the ascending leg E is the straight pipe
or inner ascending leg and is of the ordinary tubular shape and is connected
by a single junction that is screwed to the bottom of the well F by the nut F2,
and by means of the ordinary union joint the straight pipe or inner ascending
leg.E is connected to the closet or place to be flushed, is the ascending leg of
the syphon working freely over the straight pipe or inner ascending leg E.
The descending lege is of much larger diameter than the ascending leg b, and
as a conical shape working freely in the well F. The descending lege and the
ascending leg is connected together in a single casting forming a bend and is
much higher than the normal level of the water in the cistern or tank a. G is

page_text: a lever working in slots G2, cut in the cistern or tank a.
The one end of the said
lever G as a hook G which is hooked through a hole on the top of syphon c, b,
the other end of the said lever G as a hole G³ to link a chain or cord. It will be
seen by the longitudinal section Figure 1 that when the water in the cistern or
tank a is at its normal level it is below the bend of the said syphon c, b. When
it is required to flush the water closet or place to be flushed in connection with
the inner ascending straight pipe E the chain which is linked to lever G³ is
pulled down the lever working on the fulcrum in slots G2 raises the syphon c, b,
upwards and when liberated suddenly raises the water from the well E up the
descending leg and over the bend to the inner ascending leg E and the said
syphon c, b, is thereby set in action. The cistern or tank a is slowly filled again
by the ballcock d, but the syphon e, b, does not come again into action untill
the operating chain or cord H is pulled down and liberated, as understood from
the foregoing description reference being had in the accompanying drawings
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim as my invention of improvements in flushing apparatus for water closets
and other like places:-
First. The addition to or combination of a conical shape descending leg of
the syphon having a rising and falling motion over a straight ascending leg on
the pulling up and liberating of a chain or cord thereby displacing and raising
of the water from the said well over the bend of the syphon and thereby setting
up a flushing action substantially or herebefore described and illustrated in the
accompanying drawings.
