the said cylinder is fitted with a base having a hole through, which admits the
said pipe
or long syphon leg, to go through to the level, of top of flushing cistern.
The hole in charging cylinder is sufficiently slack, on the pipe to allow the water
contained in the said flushing cistern to fill the space between the said cylinder
and pipe, or long syphon leg, the top of the cylinder forms a bend, on end of
which is fixed to the top of the said cylinder, the other connects to a pipe
forming short leg of syphon, thus communicating the short syphon leg with the
said cylinder. The apparatus is put into operation as follows. The said cylinder,
sliding up the pipe or long syphon leg, & been charged with water, the water
contained in the said cylinder is lifted to a higher level than the top of pipe, cor
long syphon leg, thus charging the same, this starts the syphonic action, and the
contents of the flushing cistern is discharged, by the connection allowed by the
bend, and short leg of syphon communicating with the long leg of syphon
through the charging cylinder, the water contained in the said Hushing cistern
continues to flow out of same until it subsides to the bottom of short syphon leg,
when the action ceases.

Improvements in Syphons for Flushing Cisterns, Tanks, and
the like.
THOMAS GARFORTH RHODES Engineer, Albert Terrace, Kirkstall, Leeds
RAYMOND GAUNT Engineer The Mount Stanningley Leeds. We 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 :-
(1.) An improved form of syphon consisting of a pipe or long syphon leg over
which is free to work up and down by the action of a lever, a charging cylinder!
this cylinder is closed at the top with the exception of a pin hole; the bottom of
the said cylinder is fitted with a base having a hole through which admits the
said pipe, or long syphon leg, to go through to the level of top of flushing cistern.
The hole in charging cylinder is sufficiently slack on the pipe to allow the
water contained' in the said flushing cistern to fill the space between the said
cylinder and pipe, or long syphon leg. The top of the cylinder, forms a bend,
one end of which is fixed to the top of the said cylinder; the other connects to a
pipe forming short leg of syphon thus communicating the short syphou leg with
the said cylinder. The apparatus is put into operation as follows. The said
cylinder sliding up the pipe, or long syphon leg, and being charged with water,
the water contained in the said cylinder is lifted to a higher level than the top of
pipe, or long syphon leg, thus charging the same, this starts the syphonic action,
and the contents of the flashing cistern is discharged by the connection allowed
by the bend, and short leg of syphon communicating with the long leg of syphon
through the charging cylinder. The water contained in the said flushing cistern
continues to flow out of same, until it subsides to the bottom of short syphon leg
when the action ceases.
(2.) Improvements in syphon cistern Patent No. 24832/93 Fig. 5 consisting of
taking the syphon bend to near the bottom of the flushing cistern, and forming
the displacer in the form of a rake, thus allowing the water contained in the
said flushing cistern to be discharged to a lower level than present arrangement.
(3.) An improved form of syphon consisting of an horizontal or inclined
cylinder, and syphon pipe, the said cylinder is provided with a piston having two
discs, one for displacing the contents over the syphon bend, and thus producing
the syphon action, the other for closing the open end of cylinder during syphon
action. The water during this time is drawn in at an opening in the bottom of
Baid cylinder.
(4.) An improved form of syphon consisting of a vertical cylinder, having a
dome at the top, and the bottom provided with an enlarged base, having opening,
or openings fitted with a valve plate (or the said base may be simply provided
with holes equal to the area of the discharge pipe). The action is as follows,
the water in flushing cistern enters the cylinder by the said valve at the base,
upon raising the said cylinder by the lever, the valve closes and the water is lifted
to a higher level, than top of discharge pipe, thus producing the 'syphon action,
the water in flushing cistern then enters through the said valve and continues
until the same reaches the base of the cylinder when the action ceases, or when

cylinder.
Fig. 1 Sheet 1 shows the syphon applied to a cast iron cistern, and consists of
the bell A provided with holes A' at the bottom of bell A, also set screw B, for
holding the cup C in position, the said cup C is provided with ribs C¹, and is free
to slide up and down the syphon pipe D. The action is as follows Upon raising
the bell A, and by reason of the set screw B acting on the cup C, this is also
raised, together with the water contained in the said cup C, to above the top of
syphon pipe D, when the water falling down the syphon pipe D produces the
syphonic action, the water contained in the cistern flowing up the bell A through
holes A', and between spaces in the bell A and the cup C; when the water in the
said cistern reaches the bottom of the bell A, then the action ceases.
Fig. 2 Sheet 1 shows another arrangement in a lead lined cistern. The ball E
is connected with two pipes, one the bent syphon pipe F, the other a straight
pipe this arrangement is free to slide up and down the syphon pipe G, and is
operated by a lever. The water in cistern may fill the ball E through the slack
of the pipes F and F¹, or the ball E may be provided with a hole E¹. Also the
end of the syphon pipe F may be provided with a casting F, the object of which
is to allow the water in the cistern to be drained to a low level, this casting or
tube has holes F3 for allowing the water to pass up the syphon pipe F. The
operation is as follows: Upon raising the ball E by means of the lever the water
contained in the ball E falls down the syphon pipe G, thus producing the
syphonic action. The water in the cistern then flows up the bent syphon pipe 'F,
and thence down the syphon pipe G. The bent syphon pipe F slides freely up and
down the casing F, so that if the lever be held down the water will still drain to
the bottom of the said cistern.
Fig. 3 Sheet 1 is another arrangement and consists of a cylinder H provided
with a branch pipe H', the cylinder is free. to slide over the syphon pipe I, and
the whole is operated as before described and set forth.
Fig. 4 Sheet is another modification in which the use of straight pipes are
the principle feature, and consists of the cylinder J provided with two covers K
and K K receives two pipes K' and K³, the whole is free to slide over the syphon
pipe Land is operated as before described and set forth.
Fig. 5 Sheet 1 is another modification consisting of a cylinder J provided with
an inlet pipe J the bottom end of which communicates with the lower part of the
cylinder J, the whole is free to slide up and down the syphon leg L¹ and is operated
as before described and set forth.
Fig. 6 Sheet 2 shows an arrangement of syphon cistern provided with a
displacer in the form of a rake M, also the end of the syphon pipe N is brought
to near the bottom of the said cistern, so that the water may be drained to a
lower level than that shown in Fig. 5 Patent No. 24,832/93.
Fig. 7 Sheet 2 is another view of the displacer M showing the spaces M'.
The action is as follows Upon operating the lever the displacer flushes the water
up the syphon bend N, thus producing the syphonie action, which continues to go
on by reason of the water flowing through the spaces M' in the displacer M, until.
it reaches the level of the syphon bend N.
Fig. 8 Sheet 2 shows an arrangement of syphon provided with a cylinder O,
piston or displacer P, syphon bend Q, the piston or displacer P is provided.
with two discs P1 and P2 one for flushing the syphon the other for closing the
end of the cylinder O during the syphonic action; the water then being drawn in
at an opening O' at the bottom of the said cylinder O.
Fig. 9 Sheet 2 shows an arrangement of syphon consisting of a cylinder R,
provided with a valve S, the whole is free to slide over the syphon pipe T, or if
the cylinder R be made large enough the valve S may be dispensed with, and the
cylinder R simply provided with a hole S¹. The operation is as follows Upon
raising the cylinder R the valve S closes and the water contained in the cylinder R
is raised to above the top of the syphon pipe T, thus producing the syphonic

page_text: action, the valve S then raises and admits the water in the cistern until it subsides
to the level of the valve S when the action ceases.
Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
