Improvements relating to Syphon Flush Cisterns employed in
connection with Water Closets,
I, CHARLES FREDERICK ROBERTS, of Linfitts, Delph, in the County of York,
Gentleman, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to construct a cheap and effective method of
flushing water closet cisterns.
According to my invention the bent pipe or syphon pipe is hinged on a fulcrum
at one end near the bottom, whilst the other opposite end is made with a valve
for fitting into a valve seating formed at, the top of the outlet pipe.
This hinged syphon pipe is connected by a vertical or other form of rod to a
lever, the other end of said lever being connected by cord or chain to a pull
handle, the arrangement being such, that when the handle is pulled downward
the lever and rod above mentioned cause the syphon pipe to oscillate slightly upon
its fulcrum, in doing which the valve is opened setting in action the syphon
discharge, whereby the cistern is immediately emptied.
The lever which operates the syphon pipe may be connected by a rod at any
suitable part which on being operated rocks the syphon pipe upon its fulcrum
and so sets the syphon in action.

Improvements relating to Syphon Flush Cisterns employed in
connection with Water Closets.
I, CHARLES FREDERICK ROBERTS, of Linfitts, Delph, in the County of York,
Gentleman, 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;-
The object of my invention is to construct a cheap and effective method of
flushing water closet cisterns.
According to my invention the bent pipe or syphon pipe is hinged on a fulcrum
at one end near the bottom, whilst the other opposite end is made with a valve
for fitting into a valve seating formed at the top of the outlet-pipe.

page_text: This hinged syphon pipe is connected by a vertical or other form of rod to a
lever, the other end of said lever being connected by cord or chain to a pull
handle. the arrangement being such, that when the handle is pulled downward
the lever and rod above mentioned, cause the syphon pipe to oscillate slightly upon
its fulcrum, in doing which the valve is opened setting in action the syphon
discharge whereby the cistern is immediately emptied.
The lever which operates the syphon pipe may be connected by a rod at any
suitable part which on being operated, rocks the syphon pipe upon its fulcrum
and so sets the syphon in action.
In the accompanying drawings Fig. 1 represents my invention, where A is the
water cistern, having an outlet pipe at B. The syphon or bent pipe is shewn at C,
one end thereof being hinged at D. The opposite end of said bent pipe is pro-
vided with a valve E, which fits into a valve seating at the top of the pipe B.
A lever is employed, fulcrumed at G and connected at one end by rod H to the
syphon pipe G. When the pull handle and wire I is drawn downward as shewn
at Fig. 2; the syphon pipe is caused to oscillate upon its fulcrum D, whereupon
the valve is opened permitting the water from the cistern to pass down through
the pipe B in order to flush the water closet.
Figs. 3 and 4 illustrate other methods of operating the syphon pipe, which in
both cases is fulcrumed at D.
This arrangement and construction of syphon-flushed cisterns, is positive in its
action, cheap in the construction, and cannot easily be got out of order.
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:
In water cisterns, the employment therein of a syphon pipe, hinged at one end,
and having a valve at the opposite end, operated in the manner substantially as
herein shewn and described.
