PROVISIONAL SPECIFICATION.
Improvements in Syphon Apparatus for Supplying Water to Water
Closets, Urinals, and the like.
I GEORGE WILLIAM HARRISON of 45 Water Lane Leeds in the County of
Yorks, Cistern Maker and Brass Finisher do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved method of charging or primeing a syphon
used for flushing cisterns for water closets, urinals and the like. My object is to
gain an effectual, simple and durable syphon apparatus without the obstruction of
valves, and to prevent the waste of water.
My invention consists of a dome or half ball with an outlet at the top.
Inside
the dome I place two wings or flappers which are jointed together in the fashon of
an hinge, which are connected to the dome towards the bottom and works
mechanically upwards towards the outlet and forces the water over an ordinary
syphon bend and primes the syphon.
The hinges are made geomatrically so as to fit perfectly in the dome, they are
made in two halves which are connected together, one which we will call A is
made hollow where they are connected together in the shape of a tube which passes
through the dome, one side projecting so far, as to allow a small lever to be fixed
thereon, which is used to actuate the hinge A. The other hinge which we will
call B. is made to fit into hinge A connecting the two together by means of a solid
pin or rod which passes through the centre or hollow part of A which also passes
through the dome a little further than the hollow part of A so as to allow a second
small lever to be fixed for the purpose of actuating hinge or flapper B. From
the two small levers I connect or couple two rods, wires chains or their equivalent
which are then connected to a lever on the top of a cistern of ordinary construction
which, when worked causes the hinges or flappers to come together pressing the
water over the syphon pipe and primes the syphon.

Improvements in Syphon Apparatus for Supplying Water to Water
Closets, Urinals, and the like.
I GEORGE WILLIAM HARRISON of 45 Water Lane Leeds in the County of
York Cistern Manufacturer 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 :-
This invention relates to an improved method or means of or for charging or
priming a syphon used for flushing cisterns for water closets, urinals and the
like. The object of the invention is to obtain an efficient, simple and durable
yphon arrangement, without the obstruction of valves, and to prevent waste of
vater.

page_text: This invention consists of a dome or hollow hemispherical vessel, placed with the
base on the bottom of the cistern, and provided with holes or other openings round
the side of the base to admit water freely to the interior. To the outlet at the top
of the dome is attached the lower end of the shorter leg of the syphon. Within
the dome are placed two semicircular wings or flaps, which are hinged together
along their diametral edges about a common axis, and by means of a pair of levers
and connections hereunder described, can be moved upwards about such hinge and
allowed to fall back.
One of the wings or flaps is attached to the axial rod of the hinge, and to one of
the ends of said rod is secured one of the above mentioned levers. The axial rod
passes loose through the (side) bosses of the hinge of the other wing or flap, and
one of the bosses passes through the bearing at one side of the dome or hemispherical
vessel. The second of the above mentioned levers is cast on or otherwise secured
to the just mentioned projecting boss. Both said levers are on the same side of the
dome, but point in opposite directions when the wings or flaps are in a horizontal
position. It will be evident that if both levers are raised together, the wings will
be moved upwards simultaneously, and as they fit approximately close to the inside
of the dome during this movement, the water above them is forced upwards through
the shorter leg of the syphon, charging or priming the syphon.
The free ends of the said levers are attached by a pair of links or rods to the
weighted arm of a double armed lever, hinged in a bracket attached to the top of
one of the sides of the cistern. The draw chain or rod is attached to the opposite
eud of said lever.
The weight at the end of the weighted lever and the weight of the wings
themselves causes the fall of the latter as soon as the water is discharged from the
cistern, the suction of the escaping water holding up the wings until the discharge
is completed.
It will be evident that the nature of my invention is not altered, if the shape
of the vessel be other than hemispherical; for example semi-cylindrical, or any
other surface of revolution about the axis of the hinge corresponding to the
shape of the wings or flaps. I prefer however the hemispherical shape as being
the best.
And in order that my invention and the manner in which the same is to be
performed may be more readily and clearly understood I have annexed hereto
the accompanying sheet of drawings in which
Fig. 1 is a section of the cistern in the line of the axis or hinge of the wings,
Fig. 2 is a section through the dome at right angles to the section shewn in
Fig. 1.
Fig. 3 is a side elevation of the dome corresponding to Fig. 2.
Figs. 4 and 5 are plans of the wings.
is the dome shaped vessel.
b is the discharge pipe or sy phon.
c and d are the two wings, the wing & being attached to the axial rod i and the
wing e provided with side bosses through which the axial rod i passes loose one of
these side bosses is prolonged, so as to project through the side of the dome, having
a lever f cast or otherwise secured to said boss.
g is the other lever secured to the axial rod i.
hand i are connecting links or rods attached at their lower ends to the levers f
and g respectively, and at their upper ends by means of a short, double hinged link
to the weighted arm of the lever j. To the opposite arm of the latter is attached
the draw rod or chain.
k are the openings round the base of the dome to admit water from the cistern.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :--
1. In syphon apparatus for supplying water to water closets and the like, the

page_text: employment of a hemispherical or other suitably shaped vessel open or provided with
openings round the base and an outlet at the top connected to or communicating
with the shorter leg of the syphon and provided with hinged wings or flaps, such
that when the latter are moved or rotated about the hinge in an upward direction,
the water is forced up the shorter leg of the syphon charging or priming the same.
2. In syphon apparatus for supplying water to water closets and the like, the
combination of the hemispherical or other suitably shaped vessel a provided with
hinged wings or flaps such as c and d with the syphon pipe 6 and with means for
actuating said wings, comprising axle i, levers ƒ and g connected to the two
wings respectively and to the lever ; all substantially as herein set forth and
illustrated.
3. The improved means for charging or priming the syphon pipes of water closet
and the like cisterns substantially as herein set forth.
