IMPROVEMENTS IN WATER WASTE PREVENTORS
Year: 1884

page_text: I THOMAS GOODE MESSENGER of Loughborough in the county of Leicester,
Valve Manufacturer do hereby declare the nature of invention for "IMPROVEMENTS
IN WATER WASTE PREVENTORS" to be as follows:-
My invention relates to certain improvements in the class of flushing cisterns
worked on the syphon principle and particularly the one set forth in my specifica-
tion N° 5023-1881 The operator hitherto having no power to limit the discharge
of water to a less quantity than the contents of the cistern in which the syphon is
fixed. To obviate this, I propose to substitute for the solid plunger or float Fig 3
working in cylinder or receiver, a flat loosely fitting plate or plunger of 'metal or
other material fitted with an air valve of the spindle or other type; or construct a
valve or its equivalent to admit air into syphon at any other point at pleasure; or
otherwise to stop the flow of water from cistern into syphon and consequently to
closet or other requirement. To effect this I prefer to enlarge the lower end of
short leg of syphon, and divide the enlarged portion, so as to give two distinct
water ducts, one communicating with water contained in cistern, and the other with
water contained in vertical cylinder or receiver (the top of which I prefer to keep
under water line) the two ducts communicating in one cylindrical bent pipe forming
the syphon. Supposing the cistern to contain the proper measured quantity of
water as regulated by ball valve, when the lever or handle is pulled down the valve
in plunger becomes closed, and forces the water out of cylinder through water duct
as above described, and syphonic action is set up, drawing the water from cistern
through other duct, and continuing to flow so long as the lever is held down until
the cistern is nearly empty, when the syphon becomes charged with air instead of
water, and the action must be repeated to cause the water to flow from the cistern
again. Should it be desired to use only a portion of the water contained in the .
cistern, if, after pulling down the lever the handle or lever be released a self acting
motion opens the valve in plunger allowing the atmospheric air to pass rapidly
through it into syphon which causes the flow of water to at once cease.
plunger being carried back into position by a balance weight, and the quantity of
water required to fill cistern to water line, supplied by ball valve in the usual way,
every thing remains until the operation is repeated.

connecting the lead discharge pipe thereto by means of a brass coupling and
soldered joint in the usual way, I prefer to secure the syphon by a coupling formed
of two parts one part of which is cast with two projecting pieces to clutch two
corresponding pieces cast on syphon, so that when two pins are screwed through
half coupling to cistern bottom, the joint of syphon is tightly made. The second
part of coupling is cast to receive the lead or other metal discharge pipe slightly
"bell mouthed and screwed by the two before named pins and nuts, the joints
being made sound by indiarubber or other suitable packing. But should it be
desired to carry the discharge pipe which is the long leg of syphon, over the top of
cistern, the before named coupling may be dispensed with.

do hereby declare the nature of this invention for "IMPROVEMENTS IN 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 certain improvements in the class of flushing cisterns
worked on the syphon principle. In cisterns of this class the operator has hitherto
been unable to limit the discharge of water to any less quantity than the measured
quantity contained in the cistern in which the syphon is placed.
The arrangement in which my Invention is embodied consists essentially of four
parts.
1. A cistern-2 A syphon. 3 A vertical cylindrical tube or vessel hereinafter
called the cylinder. 4 An air valve or flow controller.
The cistern is shown at A. Figures 1 and 2. it may be of any suitable shape
dimensions and material such as those in common use for similar purposes and is
provided with a ball valve M or other means of filling it to any given water line
in the usual way.
Its
The syphon is shown at B, Figures 1 and 2 it may consist of metal or any
other suitable material and be of any 'convenient section and should be of equal or
nearly equal bore throughout I prefer however to make it of cylindrical section
The short leg of the syphon extends nearly to the bottom of the cylinder and the
head is so placed that its under surface is above the top of the cistern
extremity is at all times in free communication with the cistern so that the water
stands at the same level in both till the mechanism hereunder described is brought
into action Its lower end is enlarged and divided into two parts so as to give two
distinct water ducts, one G communicating with the water contained in the cistern
the other E with the water contained in the cylinder hereinafter described both
communicating with the cylindrical bent pipe forming the syphon. The water in
the cylinder hereunder described likewise stands at the same level as the water in
the cistern.
The cylinder is shown at C figures 1 and 2 It is constructed of metal or other
suitable material and may be of cylindrical or other desired section and.is
furnished with a plunger D and an aperture E by which it is at all times in free
communication with the short leg of syphon Its sectional area must be much
greater than that of the syphon.
The object of the cylinder is to provide a means by which the level of the water.
in the short leg of the syphon can be raised until the bend is reached and syphonic .
action commences.
"
The air valve is shewn at K figures 1 and 2 and constitutes one of my improve-
ments It may be constructed of metal or other suitable material and may be of
the type shewn or an ordinary plug tap or slide or any desired equivalent Its
object is to stop the flow of the liquid as soon as sufficient water has been
discharged,

page_text: I usually place the valve in position shown in drawing but if desired it may be
placed so as to stop the flow of liquid through the duct leading to the syphon from
the cistern thereby stopping the discharge both by cutting off the supply of
liquid and causing the syphon to become charged with air through the cylinder
or through the long leg of syphon.
The plunger D is connected by suitable mechanism, such as the well known
contrivances in common use for similar purposes, with a handle, the action of the
apparatus being as follows-When the handle or lever is pulled down the plunger
D is lowered quickly, forcing the water of of the cylinder C through the water
duct E and thereby temporarily raising the level of the water in the short leg of
the syphon and causing it to flow over the bend.
Syphonic action is thus set up, and water is drawn from the cistern through the
other water duct G which will continue to flow as long as the lever is held down.
Should it be desired to use only a portion of the water contained in the cistern,
the handle must be released, whereupon a self acting motion opens the air valve K
and allows air to pass rapidly through it into the syphon, when the flow of water
ceases at once. The plunger is carried back to its original position by means of
a balance weight and water is again admitted into the cistern in the usual way;
in this state every thing remains until the operation. is repeated.
By means of a rod or catch pin the ball H of the ball valve M is kept suspended,
to prevent water passing into the cistern while the lever is held down.
Instead of attaching the syphon to the bottom of the cistern by means of a nut
and connecting the discharge pipe thereto by means of a brass coupling and soldered
joint in the usual way, the syphon is secured by a coupling formed of two parts.
One of these parts is cast with two projecting pieces which clutch two corresponding
pieces cast upon the syphon, so that when two pins are screwed through the half
coupling to the bottom of the cistern the joint of the syphon is tightly made. The
other half of the coupling is cast so as to receive the lead or other metal discharge
pipe which is made slightly bell mouthed and secured by the two above inentioned
pins.. The joints are made sound by india rubber or other suitable packing If
desired however the discharge pipe-which forms the long leg of the syphon can
be carried over the top of the cistern and not pass through it at all.
my
Having now particularly described and ascertained the nature of said
invention and in what manner the same is to be performed I declare that what
I claim is
:-
First The 'employment of a valve tap slide or other equivalent arrangement to
cause the syphon to become charge with air or to cut off the supply of water or
other liquid from the cistern when it' is desired to stop the flow of same before the
cistern is empty.
Second-The attachment of the syphon and of the discharge pipe to the cistern
by means of a coupling formed of two parts substantially in the manner before
described.
