I MILTON SYER of 36 Rye Lane Peckham in the County of Surry Merchant
do hereby declare the nature of my invention for IMPROVEMENTS IN SYPHON
WATER WASTE PREVENTERS FOR THE FLUSHING OF CLOSETS, URINALS AND
OTHER PURPOSES to be as follows:-
In carrying my Invention into effect, I combine a Syphon tube, with a cistern of
any desired capacity, the Syphon tube is trapped with water, so as to prevent the
escape of air down the syphon tube.
This syphon tube is covered by a cap, and in this cap I fix an air valve or air pipe,
now the water filling the cistern compresses the air under syphon cap and thus
keeps the water from flowing down syphon tube I release the compressed air, and
the water rises and flows down the syphon tube, the syphon being started the
whole of the water in cistern is withdrawn. I also fit a self closing valve to the
syphon cap, closing the aperture through which the compressed air escapes, thus
preventing the return of the air.
From the foregoing it will be understood that the cistern being empty, and the
syphon trapped with water which is retained in the trap, as the water fills up the
cistern it compresses the air under syphon cap, thus holding back the water from
flowing down syphon tube. The cistern being supplied by means of a ball valve
the supply is shut off when the water has risen the required height. I now open
the air valve fitted on syphon cap, by means of a lever attached to the cistern and
at the same time I secure the ball valve so that no water can enter the cistera
until the lever is released, which shuts the air valve.
I sometimes fix this air valve on to an air pipe of any required length, so that
the air valve my be conveniently placed in seat of water closet, on the pressing or
pulling of which the air under syphon cap is released and the water flows.
The syphon tube and trapping chamber I make in one or more pieces, most
suitable to manufacture.

page_text: I, MILTON SYER, of 36 Rye Lane, Peckham, in the County of Surrey, Merchant,
do hereby declare the nature of my invention for "IMPROVEMENTS IN SYPHON
WATER WASTE PREVENTERS," and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My invention relates to improvements in syphon water waste preventers for the
flushing of closets, urinals, and other purposes, and it is designed to effect the same
in an effectual and simple manner, and with a minimum of operative movement.
In carrying my invention into effect, I combine a syphon tube with a cistern of
any desired capacity. The syphon tube is trapped with water, so as to prevent the
escape of air down the syphon tube. This syphon tube is covered by a cap, and in
this cap
I fix an air valve or air pipe. Now the water filling the cistern compresses
the air under the syphon cap, and thus keeps the water from flowing down the
syphon tube. I release the compressed air, and the water rises and flows down the
syphon tube; the syphon being started, the whole of the water in the cistern is
withdrawn. I also fit a self closing valve to the syphon cap, closing the aperture
through which the compressed air escapes, thus preventing the return of the air.
From the foregoing it will be understood that the cistern being empty and the
syphon trapped with water, which is retained in the trap, as the water fills up the
cistern it compresses the air under the syphon cap, thus holding back the water
from flowing down the syphon tube. The cistern being supplied by means of a
ball valve, the supply is shut off when the water has risen to the required height.
I now open the air valve fitted on the syphon-cap by means of a lever attached to
the cistern, and at the same time I may secure the ball valve, so that no water can
enter the cistern, until the lever is released, which shuts the air valve.
I sometimes fix this air valve on to an air pipe of any required length, so that
the air valve may be conveniently placed in the seat of the water closet, on the
pressing or pulling of which the air under the syphon cap is released and the
water flows.
The syphon tube and trapping chamber I make in one or more pieces most
suitable to manufacture.
In order that my invention may be the better understood I now proceed to
describe the same, in relation to the drawings hereunto annexed.
Figure 1 is a sectional elevation of my device complete, showing alternative
device for releasing the compressed air.
Figure 2 is a plan of the same.
A is the syphon tube leading down to the closet pan, urinal or other place where
a flush may be desired. Surrounding this is the annular wall, B, and fitting over
this, so as to form a water trap and a compressed air chamber, is the cap C. This
cap has its outer edges resting upon supports or legs D. The air valve is shown
at E, and is conveniently in the form of a float valve whose travel is kept vertical
by the guide (fitted with a stop) and bridge F. G is a weighted lever, resting upon
the float valve E, and normally retaining the same in place upon its seating. His
a pull operated from any convenient point, and which raises the lever when
required. K is the usual ball cock.

page_text: Though I have specified a float valve and weighted lever as a convenient means
of carrying my invention into effect, yet the air valve might be of other forms, and
operated by other means, such for instance as by an electro magnet brought into
action by the operator completing an electric circuit.
As shown in the drawing, the flushing cistern is full of water, a cushion of air
having been compressed in the chamber formed between C and B by the water
pressure, and the spaces between B. C¹ and A forming a water trap. Upon the
pull H being operated, the weighted lever G is raised, and the float valve E rises
from its seating, the compressed air being thus suddenly released, and the syphonage
brought into play by the water head in the direction shown by the arrows.
As the water sinks, the valve E again falls on to its seating, preventing any
break of the syphonage, until the cistern is emptied. The ball valve being brought
into play, immediately begins to refill the cistern, and produce anew the conditions
required for a flush.
My device it will thus be seen can be used as a continuous intermittent flush, or
the ball may be secured until the cistern is emptied, and then allowed to drop and
refill the same. L shows an air pipe leading to the valve M, normally, held closed
by a spiral spring, which may be released by a push N, thus allowing the com-
pressed air to escape and the syphonage to be established. Where this is employed,
the valve E would not exist, the only aperture into the cap being at O.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, I declare that what I claim is
1st In a syphon water waste preventer, the combination of a syphon tube with
surrounding annular wall and double cap, in order to provide a water trap and an
air chamber, substantially as and for the purposes specified.
2nd The combination therewith of any self closing air valve, and convenient
operating device, in a flushing cistern, substantially as and for the purposes
specified.
3rd The alternative combination therewith of an air pipe and valve in a flushing
cistern, substantially as and for the purposes specified.
4th The specific combination therewith of a float valve, weighted lever, and pull,
in a flushing cistern, substantially as specified.
