Improvements in Flushing Cisterns.
I, FREDERICK JAMES BOSTEL of 73 Ebury Street, in the County of London,
Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a method of and means for actuating.
the syphons of flushing cisterns so as to ensure more effective action.
In carrying out my invention I provide the usual cistern fitted with a ball cock
inlet valve and a syphon discharge.
I close the short arm of the syphon normally by means of a plug valve attached
to which is a cord, wire, or other connecting means connected at opposite end to
one arm of a lever pivotted conveniently to one side (or both sides) of the cistern,
and such lever having at the other extremity or arm a hanging bucket or subsidiary
cistern which may be of inverted cone shape and which when filled with water
raises the plug from its seat and actuates the syphon, so giving the discharge to
the closet.
In order to gradually and intermittently fill or charge this bucket or cistern I
drill or perforate the upper part of the ball cock valve and fix therein one end of
a small tube or pipe and in a convenient position above the bucket before described
I pivot a small tipping cistern so arranged as when filled to tip its contents into the
bucket counterbalancing the plug valve before referred to.
The small tube or pipe from the head of the ball valve I lead up to and over the
tilting cistern so that it may discharge therein.
The operation is as follows. On the cistern becoming filled in the ordinary way
the ball rises and the ball valve is closed when the water in a thin stream will rise
through the small tube and fall into the tipping cistern and this as soon as over-
weighted will discharge into the bucket counterbalancing the plug valve of the syphon
which plug will then be raised and the syphou put in action. The counter-
balancing bucket is gradually emptied by means of a small hole or holes or other
convenient device.

COMPLETE SPECIFICATION.
Improvements in Flushing Cisterns.
I FREDERICK JAMES BOSTEL of 73 Ebury Street, Pimlico in the County of
London, Sanitary Engineer 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 aud by the following statement :-
And in order to more clearly explain my said invention I have attached to this
Specification a drawing which is a view of my improved flushing cistern with part
of one side cut away so as to shew the mechanism more distinctly.
The object of my improvements is to provide means for actuating the syphons
of flushing cisterns so as to ensure more effective action and for this purpose I
provide a cistern A of the usual character fitted with a ballcock inlet valve B and
a syphon discharge C. I close the short arm of the syphon normally by means of

page_text: a plug-valve D. attached to which is a cord, wire, chain or the like E connected
at its opposite end to one arm F of a lever pivotted conveniently as at G on to a
central bar H. or to one side of the cistern, and on the opposite arm J of the lever
I hang a bucket or subsidiary cistern K. which when filled or partially filled with
water raises the plug D from its seat and so actuates the syphon thus giving the
discharge to the closet.
In order to fill or charge the bucket K. intermittently I drill or perforate the
upper part of the ball cock say at L. and secure therein one end of a small tube M.
and in a convenient position above the bucket K. (say as at N) I pivot a small
tipping cistern such as O. arranged so that when filled or nearly so its contents
will cause it to tilt or turn over on its pivot such contents being discharged into
the lower cistern or bucket K. which then descends and operates plug valve D and
syphon C. a small hole in the bottom of the bucket K allows the gradual escape
of water therefrom and when a certain quantity has been thus discharged the
plug D overcomes the weight of the bucket K and returns to its seat thus closing
the short arm of the syphon.
After the discharge the ball P. falls and opens the ball cock B when the water
passes into the cistern until it is shut off by reason of the ball having risen to its
normal position, and when this takes place and the water from the usual supply
pipe ceases to run into the cistern it rises through the small pipe or tube M and
falls into the small tipping cistern O until it has risen therein to the necessary
height for overbalancing same and tilting the contents into the bucket K. so raising
the plug D again and this action continues so long as the water supply is constant.
Or, in place of filling the tipping cistern as before described I may divide the
main cistern and fix my subsidiary bucket K and tilting cistern O in one compart-
ment thereof, the syphon and ball or other valve from the supply pipe being in the
other compartment from which when filled to a certain height a portion of the
contents may pass through an overflow pipe or channel into the tilting cistern O.
or I may tap the supply pipe in front of the ball or other valve and carry a pipe
of small diameter direct to the tilting cistern or other means for filling this cistern
may be employed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same may be performed I declare that what
I claim is.
1. In flushing cisterns the use of a subsidiary hanging bucket or cistern, inter-
mittently and suddenly filled or charged by the tilting or upsetting thereinto of
the contents of a small tilting cistern conveniently placed, for the purpose of
withdrawing by its weight (when fully charged) the plug of a plugvalve inserted
in the short arm of a syphon substantially as hereinbefore described with reference
to accompanying drawing.
2. Perforating the upper portion of a ball cock valve and inserting one end of a
small tube so that when said valve is closed the water from the supply pipe may
pass up the said tube and deliver into a tilting cistern conveniently placed,
substantially as described and with reference to drawing.
3. In flushing cisterns the combination of a hanging subsidiary bucket such
as K, forming when charged an overbalancing weight, with a syphon having on its
short arm a plugvalve connected to one arm of a lever by a cord or chain such
as E. a tipping cistern such as O and a means for filling sanie gradually such as by
a small pire or tube connected to the ball cock or other valve substantially as
..hereinbefore described with reference to drawing.
4. The construction and arrangement of flushing cistern substantially as herein-
before described and illustrated by accompanying drawing.
