IMPROVEMENTS IN WATER WASTE PREVENTERS
The objects of my invention are to produce a water waste preventer for closets
urinals and the like from which the water is discharged by the oscillation or
inclination of the vessel in which the water is contained and to effect this
discharge without putting any undue strain on the ball supply valve lever while at
the same time my apparatus is very certain in its operation and effectual in
preventing leakage and waste of water. I can also so arrange and fit this
apparatus that in addition to the flush which is first delivered an effectual after
flush is also provided by one and the same action
With these objects I make a cistern of any suitable material and of a convenient
shape and size but I prefer to make it of a quadrantal section so as to secure one
of its plane sides against the wall or elsewhere. In this cistern the oscillating
vessel is supported horizontally lengthwise which vessel is preferably of a semi-
circular section. The water supply pipe passes through the upper part of ono of
the ends of the cistern into the oscillating vessel and has a closed end but a narrow
opening is made through the lower side of the pipe near the closed end inside the
oscillating vessel through which the water can pass. I prefer to make the end
part of this pipe with a tapered exterior surface. Fitting tightly round the end
part of the pipe I place a casting of metal containing a passage for the water
which passage commences with a narrow opening corresponding with the opening
in the pipe and terminates with any suitable ball valve. This casting is secured
to the end of the oscillating vessel and may support the same by its bearing round
the supply pipe or a separate bearing may be formed round the said pipe for the
vessel. The openings in the pipe and in the casting are made to coinmunicate
when the vessel is on a level or in position to be filled. The other ond of the
Drine C71

page_text: vessel is supported in the same manner on a pipe which has a similar bearing
valve with passages for the water on the outside of the cistern. This acts as an
overflow pipe. A lever is attached to the oscillating vessel to which is connected
the pull. In the cistern the discharge pipe is preferably placed at or near one end
thereof and near the pipe may be constructed a low transverse midfeather or
vertical partition in the lower part of which close to the bottom of the cistern are
one or more small holes.
The action then is as follows. The oscillating vessel being empty and in a level
position the water passage is formed to the ball valve which admits the water
until the vessel is sufficiently filled and the ball valve shuts off the supply. The
pull then inclines the vessel and empties the water out of the same into the
cistern. Immediately the vessel is inclined the opening in the casting no longer
corresponds with the opening in the pipe and no water therefore can enter until
the vessel is brought back to its former position. The water which has been
emptied into the cistern passes away by the discharge pipe and effects the flush
but when the cistern is so constructed a certain proportion of the water is retained
by the transverse midfeather or partition which afterwards passes away slowly
through the holes and gives the required after flush.
In order to prevent any water splashing over the edges of the cistern from the
sudden emptying of the vessel one lateral edge of the cistern may be bent over
inwardly a certain distance while on the other side I may place below the vessel
an inclined plate to act as a broaker for the water and prevent it rushing up the
side of the cistern.
In order also to ensure the vessel coming back to the level position after having
been inclined I may counterweight the same but I profer to pivot it a little out of
the centre line thereof so that the side of the vessel which is raised when it is
inclined shall be a little larger and heavier than the other sido. At the same time
this counterbalancing of the vessel cannot cause it to pass beyond the level position
by reason of the bont over lateral edge of the cistern.

IMPROVEMENTS IN WATER WASTE PREVENTERS
The objects of my invention are to produce a water waste preventer for closets
urinals and the like from which the water is discharged by the oscillation or
inclination of the vessel in which the water is contained and to effect this discharge
without putting any undue strain on the ball supply valve lever while at the same
time my apparatus is very certain in its operation and effectual in preventing
leakage and waste of water. I can also so arrange and fit this apparatus that in
addition to the flush which is at the first delivered an effectual after flush is also
provided by one and the same action.
In order to explain my invention I refer to the accompanying drawing.
Figure 1 is a transverse vertical section of my apparatus.
Figure 2 is a longitudinal vertical section of the same taken at a. b. in Figure 1.
Figure 3 is a longitudinal vertical section on an enlarged scale of one end
of my apparatus shewing in what manner the water is admitted thereinto.
Figure 4 is a cross section taken at c. d. in Figure 3.
Figure 5 is a longitudinal vertical section also on an enlarged scale of the other
end of my apparatus shewing the overflow thereof.
The letters refer to the same parts in all the Figures.
The cistern A is made of any suitable material and may be formed of any
convenient shape but I prefer to make it of a quadrantal section as shewn in
Figure 1 and its plane side A' is then easily secured against the wall or elsewhere.
Lengthwise in the cistern A is supported horizontally an oscillating vessel B which
vessel B is preferably of a semicircular section as shewn in Figure 1 and is
supported at each end by the water supply pipe and by the overflow pipe as is
hereinafter explained. Referring to Figures 3 and 4 the water supply pipe C is
firmly secured to the upper part of one of the ends A³ of the cistern A. and passes
through into the oscillating vessel B. The end of the pipe C.is closed as shewn
at D and a narrow longitudinal opening E is made through the lower side of tho
pipe C near this closed end D which opening E is inside the oscillating vessel B.
A metal casting F of a suitable shape is fitted round the end part G of the pipe C
inside the vessel B and can oscillate thereon and to prevent the escape of any
water thereat the meeting faces of the two parts that is to say the pipe and the
casting are inade perfectly true and smooth. I also prefer to taper this ond part G
of the pipe C so that when required as the parts wear or otherwise the joint can be
rendered perfectly tight by screwing up the nut H on the end D. The casting F
contains a passage for the water which passage commences with a narrow
opening K corresponding with the opening E and terminates in the usual shape of
a circular or other section where it is fitted with any suitable ball valve L. A
bracket M which may preferably be made in the same piece therewith secures the
casting F to the end B' of the oscillating vessel B and the said casting F may
thereby support the said vessel B as shewn in Figures 3 and 4 or a separate
bearing may be formed round the pipe C to support the oscillating vessel B. Tho
opening K communicates with the opening E when the vessel B is on a level as
shewn in the drawing. Referring to Figure 5 the other end of the oscillating
vessel B is supported round the end of the overflow pipe N. This pipe N is firmly
secured to the upper part of the other end A³ of the cistern A and passing through
the same opens into the oscillating vessel B. Round the end part of the pipe N° is

page_text: fitted a casting 0 of a suitable shape which can oscillate thereon and the lower
part of this casting O is secured to the end B of the vessel B. A lover or bent
rod P is attached to the oscillating vessol B to which rod P is connected the pull R.
The discharge pipe S is preferably placed at or near one end of the cistern A and
near the pipe S may be constructed a low transverse midfeather or vertical a
partition T in the lower part of which close to the bottom of the cistern are one or
more small holes V.
The action then of this apparatus is as follows. The oscillating vessel B being
empty and in a level position a passage for the water is formed from the supply
pipe C through the openings E and K to the ball valve L whereby the water is
admitted until the said vessel B is sufficiently filled and the said ball valve L shuts
off the supply. The pull R can then incline the vessel B into the position shown
in dotted lines in Figure 1 and the water is emptied out of the said vessel B into
the cistern A-Immediately the vessel B is inclined the opening K no longer
communicates with the opening E and no water therefore can pass until the
vessel B is brought back to its former level position. The water which has been
emptied into the cistern A passes away through the discharge pipe S and effects
the flush but when the cistern A is fitted and arranged as shewn in Figures 1 and 2
a certain proportion of the water is retained by the midfeather T which afterwards
passes away slowly through the hole or holes V. to the pipe S and gives the
required after flush.
In order to prevent any water splashing over the edges of the cistern by reason
of the sudden emptying of the oscillating vessel the outer lateral edge of the cistern
may be bent over inwardly in one or more places or throughout its length as shewn
at A' in Figure 1 while on the other side A'I secure below the vessel B an inclined
plate W which extends the whole length of the cistern A and acts as a breaker for
the water to prevent the same rushing up the said side A¹.
In order also to ensure the vessel B coming back to the level position after
having been inclined I may counterweight the same but I prefer to pivot and
support the said vessel B a little out of the centre line thereof as shewn in Figure 1
so that the side B that is raised when the vessel B is inclined shall be a little
larger and heavier than the other side B. This aforesaid counterweighting or
counterbalancing of the vessel B cannot cause it to pass beyond the level position
by reason of the bent over edge A' of the cistern A which said edge A engages
the side B' of the oscillating vessel Bas shewn in Figure 1.
In conclusion I would state that I have shewn in the drawing the shapes and
details and methods of construction of the various parts of my apparatus that I
consider the best and most suitable for carrying out my objects as herein before
declared but at the same time I would have it clearly understood that I do in
no wise limit myself to the said shapes or details or methods of construction ns
shown in the drawing for all the said parts may be made of such shapes and
in such a manner as may be most convenient and suitable in each case.
Having thus particularly described and clearly ascertained my invention and in
what manner the same is to be performed I claim as my invention which is
protected by the herein before in part recited Letters Patent
