Improvements in Siphons and Ball Valves Employed in Siphon
Cisterns for Water Closets and the like.
I JOHN HENRY DUKE, of 303 Hessle Road, Hull in the County of York,
Plumber, do hereby declare the nature of this invention, to be as follows:-
The object of my invention is to construct a siphon for cisterns which shall.
greatly economize space, and shall be direct in its action, and give a quick and;
powerful flush, the ball of the valve in connection with the cistern being much..
lighter and cheaper than those hitherto employed.
I construct my invention as follows:-
I employ a tube having an outer cover or dome, on the inner tube and projecting.
outside the outer cover, I attach a tube or short pipe having an upward turn,
above this pipe and preferably attached to the outer dome or covering I employ.
a suitably bent or forked lever having a valve covering or cap. pivotted or other-
wise connected to it,, one of the forks of the lever being preferably weighted, the-
covering or cap fits on the mouth of the small tube, a chain, wire or the like is
connected to the weighted part, such chain or the like passes over a pulley
attached to any suitable; part of the cistern. To operate the siphon the said chain
is pulled and lifts the: valve covering, water being admitted into the short pipe or
valve causes suction in the siphon which immediately gives a quick and powerful
flush.
In place of employing the nut and tail, (which would be necessary for sanitary,
and iron cisterns only) I may dispense with the same for lead cisterns, and form a.
large. flange at the bottom of the outer cover, the flange being soldered or otherwise.
attached to the bottom of the cistern without screwing.
The ball of the tap may be made of cork coated with a rubber or other-suitable -
solution, this makes the float or ball much lighter and therefore more buoyant,
and saves all soldering, there is no liability of it getting filled with water as is the-
case with the metal ones, which very frequently carode, the acids or the like in
the water eating the solder away which allows water to enter the ball thus
preventing it floating.

I JOHN HENRY DUKE of 33 Hessle Road Hult in the County of York
Plumber, 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 :-

DESCRIPTION OF DRAWINGS.
Fig. 1 shows side elevation of my improved siphon for water closet cisterns and
the like.
Fig. 2 shows sectional view of Fig. 1 with lever for lifting valve mounted on
short tube or valve opening.
Fig. 3 shows flanges on outer and inner vertical tubes to allow of soldering to
cistern bottom if used for lead cisterns.
I construct my invention as follows:-I employ a tube A having an outer cover
or dome B, on the inner tube and projecting outside the outer cover, I attach a
tube or short pipe C having an upward turn, above this pipe and preferably
attached to the outer dome or covering I employ a suitably bent or forked lever D,
having a valve covering or cap E pivotted or otherwise connected to it, one of
the forks of the lever being preferably weighted at F; the cap or covering fits
on the mouth of the small tube, a chain wire G or the like is connected to the
weighted part, such chain or the like passes over a pulley attached to any suitable
part of the cistern.
To operate the siphon the said cord G is pulled and lifts the valve covering E,
water being admitted into the short pipe or valve C, causes suction in the siphon
which immediately gives a quick and powerful flush.
In place of employing the nut H and tail J which would be necessary for
sanitary and iron cisterns only, I may dispense with the same, and for lead cisterns
form a large flange K at the bottom of the outer cover B and tube A see Fig. 3, .
the flange being soldered or otherwise attached to the bottom of the cistern.
without screwing, holes L being formed in the outer cover B for the water to be
drawn through when the flushing takes place, or a small seat may be soldered into
cistern bottom and siphon screwed into this; the ball of the tap may be made of
cork coated with a rubber or other suitable solution, this makes the float or ball much
lighter and therefore more buoyant and saves all soldering, there is no liability of
it getting filled with water as is the case with the metal ones which very frequently
corrode, the acids or the like in the water eating the solder away, which allows
water to enter the ball thus preventing it floating.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
1. A siphon consisting of a vertical tube A, with outer cover B, and with short
tube C,.having valve E, actuated by means of weighted lever D for flushing
cisterns in the manner and for the purposes, substantially as shown and
described.
