A SYPHON WATER. WASTE PREVENTER
Year: 1884

page_text: I, RICHARD GIBBINGS MEDLAND of 4 Carshalton Road in the County of Surrey
Plumber I do hereby declare the nature of my invention for A SYPHON WATER.
WASTE PREVENTER to be as follows:--
'
=
A square or angular cistern of zinc or other metal fitted with a syphon, the
syphon consisting of a cylinder attached to a cone with sealed top-the large
part of cone being at. top to give impetuous motion, the bottom of cone passing
through cistern attaches to service pipe.. The syphon action is caused by an indian,
rubber valve working in cylinder on a metal disc attached to a gun metal shaft,
the shaft working. through diaphragm in bottom of cistern with metal weight
below to bring valve down. A crank lever, is fixed to bottom of cistern under
the weight with chain and ring pull. The ring being suddenly pulled, raises
the reverse end of lever which pushes the valve up the cylinder driving the water.
up in the cone, causing the syphon to start. The diaphragm is onclosed between
two brass flanges, the inner edges being rounded to allow for expansion of
diaphragm. The top flange is soldered to bottom of cistern.
・
The bottom flange is fixed to the top flange with brass screws, and by dis-
connecting these screws, the bottom flange, diaphragm, shaft and valve can be
removed with ease to put new rubber valve or diaphragm. The overflow pipe is
below top of Syphon where cone and cylinder is attached, so that there cannot be
any waste of water down the service pipe, the action of valve reducing water in
cistern. The cistern is supplied by a ball valve which regulates it according to
syphon. The lever under cistern can be worked by door action, seat action, treadle
action or by ring pull as before stated.
"
A connecting rod from lever to urinal W.C or lateral waste with indian rubber
globular seating to hold water in urinal W.C. or lateral, the valve being pulled up
and down through a metal guide by the aforesaid ring and pull. The urinals to
be of cast enamelled iron or earthenware.
I
-
The grating
In front of valve there will be au elliptical perforated grating.
having flanges to slip in a groove formed in urinal, an overflow at back of grating
one inch below rim of urinal coming down at back can be attached to the waste or
can be carried through wall to drain as necessary so that the water always stands
in urinal when the. valve is down.
This valve and cistern can be worked together by door action, or treadle action..

I do hereby declare the nature of my invention for THE PREVENTION OF WASTE
OF WATER AND FOR FLUSHING W.C's URINALS LATRINES &c. and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
A square or angular cistern of zinc or other metal with cylinder A inside coming
down within of an inch of bottom, the top of cylinder being sealed and attached
at side to a taper cone B, the taper cone passing through and being soldered to.
bottom of cistern C projecting 2 inches below the bottom with open end for service
pipe or union of service to W.C's &c. The water flowing from cistern up into
cylinder to water line D inch below partition of cylinder and cone Q. The
syphon motion is caused by a thin rubber seating E, working in and fitting
cylinder, the rubber being supported by a metal disc F being an inch less than
cylinder allowing the water to flow by to water line. When being pushed up
supports the seating which drives the water into cone, the seating being thin
rubber, having no support on top is sucked up, by the action of syphon, thereby
leaving a full water way.
The metal disc and rubber seating working on and screwed with flange and nut
to a gun metal shaft G. The bottom of shaft working in a red rubber diaphragm Ḥ
through bottom of cistern. A metal weight I screwed to bottom of shaft outside
of diaphragm to bring back valve after action. The outer edge of diaphragm is
screwed between brass flanges J to make it water tight, the top flange being
soldered or attached to cistern, and the bottom flange being screwed with five
screws to top. By taking out screws the valve can be disconnected for repairs.
Attached to bottom flange is a domecal metal shield K to protect diaphragm.
A hole in shield to allow weight to work through.
A weighted lever L working in centre on staple M attached to cistern. One-end
of lever with hole for chain and pull N, the weighted end being flat at top works
direct under weight of shaft. By pulling the ring, the lever pushes the weight,
shaft and valve, up the cylinder driving the water from the cylinder into the cone,
causing the syphon to discharge.
The cone being as large again on top, gives the greater weight of water, and
causes a rapid flush. The cistern is fitted by Water Company's pattern ball valve O
which shuts off to water line before described.
An overflow P is inserted in the side of cistern at of an inch above water line,
being a of an inch below partition in cylinder, so that the water cannot waste
down the W.C. but will run through the overflow at side in case of leakage of ball
cock or other causes. It can be seen by Water Company's servants. It can be
worked by ring pull, door action, treadle action, or seat action,

page_text: When the cistern is empty and the syphon draws air at the bottom of cylinder
the after flush has greater pressure, baving the whole weight of water from the top
of taper cone. Thus giving a very rapid flush with small quantity of water.
I declare that what I claim is
My own invention for the prevention of waste of water, and for the improved
method of flushing W.C's, urinals, drains latrines &c.
