Improvements in Syphon Flushing Cisterns and in Water Waste
Preventers.
I, WALTER DEELEY of Phoenix Works Holloway Head, in the City of
Birmingham, Sanitary Engineer, do hereby declare the nature of this invention
to be as follows :-
This invention relates to syphon flushing cisterns, and water waste preventers, of
that type, in which a plunger in conjunction with a bell or movable jacket,
(surrounding a stand pipe) is employed, for forcing water to a higher level, in
order that the same shall pass down the down-pipe, hence the removal of
the air contained within it, and a partial vacuum obtained, which through its
instrumentality, allows the water in the cistern to rise, and hence a final flushing,
following an initial one as aforesaid.
By my invention, the parts of a cistern, are simple in construction, efficient and
semi silent when in use, and not liable to get out of order.
In carrying out my invention 1 take an ordinary tank, having fitted within the
middle of its bottom, and erected up the middle of the body of the tank, an erect
stand-pipe, with its upper part cupped or expanded for collecting water into the
interior of the same.
The foot or shank of this stand-pipe, passes through a hole in the bottom of the
cistern and is there secured by ordinary clamping nuts, in conjunction with a
union joint.
The foot or base part of the stand pipe, has four or other number of short
inclined ribs, tapering outwardly from the base, towards a collar or swell of the
foot part, and at a short distance from the said lower end.
Surrounding the lower part of this said stand-pipe, (which is a hollow and erect
pillar, leading to the down-pipe of the cistern,) is a loose wall, elevated from the
bottom of the cistern by an annular flange or foot, so as to leave clearance between
the said bottom, and well, for the inward passage of water, when flushing, through
piercings or holes in the bottom of the said well.
Surrounding the stand-pipe, is a conical bell, having at its base, an expanded
flange or plunger, of about the inside diameter of the well, so that the said flange
resembles a plate at the foot of the bell, which works piston-like within the said
well, and is prevented from coming flat to its bottom, by lifts or studs.
Circumferentially encircling the lower part of the stand pipe, and over the
piercings of the well, and between the underside of the flange or plate of the bell,
is a loosely fitted disc valve, which closes the piercings in the bottom of the well,
when the combined bell and extended flange descends, but rises from its seat, and
from over the piercings aforesaid, when the said combined bell and flange is lifted,
by hooked ends of a forked lever, taking under trunnion centres on the two opposite
sides of the bell near its upper end.
The lever may consist of a forked arm, with a rear stem, which latter is jointed
about its middle to the double branches of a forked bracket, distending inwardly
from the end of the cistern, which is provided with the usual ball-cock fittings,
overflow, and other like accessory parts.

page_text: Thus, the slight vacuum created by the lifting of the bell and its flanged
bottom, causes water to instantly force itself into the lower part of the chamber,
under the flange, up the sides of the downpipe, over its top, and down its middle.
The releasing of the lever causes the bell to gravitate by its own weight (the
disc valve to take to its seat over the opening) and so force the water piston-like,
from out of the well or chamber, up the interior of the bell, and over the top of
the down pipe, and down the same, hence the flushing, by the partial vacuum
created, which causes an unequal atmospheric pressure inside and outside the
cistern.

Improvements in Syphon Flushing Cisterns and in Water Waste
Preventers.
I, WALTER DEELEY of Phoenix Works, Holloway Head, in the City of
Birmingham, Sanitary Engineer, 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 :-
This invention relates to syphon flushing cisterns, and water waste preventers, of
the well and plunger type, as hereinafter described.
Figure 1 of the accompanying drawing, represents in longitudinal vertical section,
a syphon flushing cistern, and a water waste preventer, constructed, arranged and
provided, or fitted with improvements made according to my invention.
The bell and plunger, which is shown fitted and working within a fixed or an
attached well or chamber, is resting at the bottom of the well, but elevated to a
short distance from the same by distance feet, so as to leave sufficient clearance for
the free passage of water, through the inlet holes in the bottom of the said well,
when the disc valve is lifted.
Normally the said disc valve closes the said inlet holes, and thereby confines the
water located between the underside of the plunger part, and within the bell, so
that the raising of the said combined bell and plunger, leaves free the valve,
which rises.

Figure 2 represents a portion of the said cistern, with the combined bell and
plunger lifted, and the disc valve elevated, with the same coming against stops,
at the terminations of guides or rib snugs, at the foot of the down pipe, which
answers both as a guide and stop to the valve, and also constitutes a well to the
cistern or flush box bottom.
Figure 3 represents a topside plan of the well, with the valve removed; and it
also shows the standpipe with the guide ribs, situated at four equi-distant points.
Figure 4 represents a complete topside plan of the said Figure 1, with the fore
or picking up part of the lever broken off, and with the bell broken away from the
plunger base, so as to exhibit more clearly, the top of the disc valve, and the inlet
openings in the bottom of the well, which are shown in dotted lines.
a is a cistern or flush box, open at top, and covered by a lid 7. b is an erect
standpipe with its lower part , directed through the bottom of the cistern, whilst
the upper end is bell mouthed and marked .
The said lower end &, is outside wormed, upon which, affixing nuts c, c³ take, as
hereinafter described.
Disposed at a short distance from the base of the said stand pipe, are guide
ribs with stops, and shoulders, which latter, come upon, or take within
seatings d, of a well or open topped vessel d, having a foot d³, at the underside of

page_text: its middle part, upon which the said well stands, and is thereby elevated above the
bottom of the cistern or flush box a.
By the screwing up of the nut c', around the neck b³, the said standpipe is drawn
downwardly, and the shoulders 6, of the guide ribs 6, made to impinge upon the
seatings d, and thereby affix the well to the bottom of the cistern, and around the
base of the standpipe.
e is a down pipe leading from the standpipe, and connected to the same by
the nut c, of a union joint.
Situated at the middle part, and upon the topside of the bottom of the well, and
circumferentially around the foot of the stand-pipe, is a disc valve f, composed of a
plate of metal, india-rubber or other like solid substance, and adapted to cover
slotted holes or inlets d*, directed in a circular manner around the standpipe, and
wherethrough liquid from the flush box passes, when flushing is in operation, but
closed by the said valve, when water located between the underside of the
plunger g, and within bell h, requires to be lifted or elevated above the open top of
the standpipe, (for the purpose of creating a partial vacuum down the said
standpipe), by the forcing action of the said plunger, which works free and piston-like
within the well, which to all intents and purposes, is a water cylinder located at the
bottom of the cistern, and under the water contained within it.
A clearance is left on the underside of the said plunger for the free passage of
liquid when the said plunger is down, by feet or distance stops g'. The combined
bell and plunger is picked up by the hooked end, of the inner end , of a lover i,
jointed at is, and having an outer end is, to which a pull j, is connected.
The said inner end i³, takes upon trunnion ends n². located on the two opposite

page_text: preferably oval in figure, and having fitted, and freely within it, a disc plunger g, of
a combined plunger and bell g, h, picked up by an auxiliary or cranked arm, k',
having a slotted acting end, which takes upon trunnion ends on the opposite
sides of the bell. This said auxiliary arm k', is integral with or carried by the
primary lever k, which is jointed at k³, and has a counterpoised weighted end k*, for
the bringing back of the said lever, and combined bell and plunger, to their normal
positions as represented in Figure 6.
The other parts are marked with the same letters of reference as before.
Assuming the parts to be in positions represented in Figure 6, the pulling of the
lever k, by the pull k, turns the said lever about the centre ³, depresses the arm k',
and presses down the combined bell and disc plunger g, h. The short arm k¹ of the
lever, is prevented from rising too far by a fixed stop a.
Portion of the water confined in the lower part of the well or water cylinder,
below the plunger, is compressed and then lifted up the inside of the bell, to above
the open top of standpipe, when the said water passer over the said open top,
and down the throat or passage of the same, when by such action, a vacuum or
a partial vacuum is created by the displacement of the air within the said standpipe
and downpipe, hence the creation of flushing.
Immediately the flushing commences, the water within the flush box or cistern,
passes, by its pressure, through the passages or openings d', which rises to a
sufficient extent to make a free clearance for the inside passage of the water.
Water also passes into the bell, through the joint between the plunger, and well or
water cylinder.
By my invention the whole or nearly the whole of the water in the cistern is
extracted at each flush.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First: In a syphon flushing cistern of the well or water cylinder type,
providing the said well, or the water cylinder, which has inlet holes or passages
through its bottom with a valve, or a disc valve substantially as described and
set forth.
Secondly-In a syphon flushing cistern, a well or water cylinder having holes
or inlet passages through its bottom, and a disc or like valve, adapted to cover the
said holes or passages, on the starting of the flush, and which well and valve are

Thirdly :-
:-In a syphon flushing cistern, of the well or water cylinder type, the
combination with a well or water cylinder, having holes through its bottom, and a
disc valve, adapted to cover the same at times, of a combined bell and plunger, with
feet or distance rests upon the underside of the latter, substantially as described
and set forth.
Fourthly In a syphon flushing cistern, the combination with a valve, and water
cylinder, with an elevated bottom, of a valve guide and stop 64, 6, as set forth.
Fifthly In a syphon flushing cistern, the construction and arrangement of the
parts, and the affixing of the permanent well in position, substantially as described
and set forth in Figures 1, 2, 3, 4 and 5.
