Improvements in Syphon Flushing Cisterns or Water Waste
Preventers.
We, HERBERT EDWARD BRICE of Alexandria Road, Edgbaston, in the City
of Birmingham, Brassfounder, and JOHN JONES of 40 Sydney Street, Chelsea,
London, Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to syphon flushing cisterns or water-waste preventers, of
the well and plunger type, and has for its object, a more efficient flusher, without
any loose parts, than has heretofore been made.
According to our improvements, we fit within an ordinary flush-box or tank a
slightly raised well, with piercings or holes through its middle and a stand pipe
having its mouth or flared entrance standing above the water level. Working
freely and telescopically over the standpipe is the middle leg of a three-legged
syphon, which is picked up by a lever whose forked and forward end engages with
studs or traanions upon the two opposite sides of the syphon. The middle and
bearing part of the lever has pockets, which are engaged by a sliding movement,
with opposite pegs extending inwards from and formed integral with a bifurcated
bracket forming the fulera about which the lever turns as a centre.
The outer end of the lever is fitted with a pull, whilst the cistern itself is provided
with the usual ball-cock, doat and over-flow.
The entrances to the respective legs of the syphon are circumferentially
surrounded by a piston-like flange suitable for working within the well, whose walls
stand about 5 inches above the bottom of the tank.
The tops or crown of the legs are open to one another so that the water has
a free passage through the said legs to the open end of the stand pipe which is
located within the middle leg.
OPERATION.
:
To operate the cistern, depress the lever by the pull, when the inner end of the
arm is lifted, and with it, the syphon is picked up and its flanged end taken to near
the top of the well. Water fills up the well and occupies the space vacated by the
piston, when the pull is released, and the triple-legged syphon and its cognate
parts fall by their own weight and force the liquid up the outer legs and up the
clearances between the middle leg and the down-pipe, the respective streams of
water meeting above and flowing down the stand-pipe, the water acting as a water
piston, displaces the air, and creates a partial vacuum in the inside upper part of
the syphon, hence the initial starting of the syphonic action, which is then continued
in the ordinary way consequent upon the stand pipe, combined with the down pipe,
forming the longer leg to the syphon system. The flow of water or syphonic
draught is continued until the cistern is empty.
The holes in the bottom of the well may come opposite the open bottoms to the
legs, and in order to prevent the syphon from twisting, the said well and piston
flanged end may be made of a D-figure,
In another form of our improvements, the initial starting of the flush may be
accomplished by depressing the three-legged syphon, that is, the normal position of
the syphon is lifted," with the piston end coming near the mouth of the well, when
by pulling the lever through the pull, the syphon (which may be counterpoised,

page_text: then descends and forces the liquid up the legs and starts the syphonic action of
the cistern.
By making the pivot ends upon which the lever turns in manner as described, the
employment of loose pins is dispensed with.

Improvements in Syphon Flushing Cisterns or Water Waste
Preventers.
We, HERBERT EDWARD BRICE of Alexandria Road, Edgbaston, Brassfounder,
and Jons JONES of 40 Sydney Street, Chelsen, London, 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 or water-waste preventers,
preferably of the well and plunger type, and has for its object, a more efficient
ilusher, without any loose parts, than bis heretofore been made.
According to our improvements, we fit within an ordinary flush-box or tank a
slightly elevated well, with piercings or holes through its bottom and a stand pipe
having its mouth or flared entrance standing above the water level. Working
freely and telescopically over the stand pipe is the middle leg of a three-legged
syphon, which is picked up by a lever whose forked and forward cud engages with
studs or trunnions upon the two opposite sides of the syphon.
The outer end of the lever is fitted with a pull, whilst the cistern itself is provided
with the usual ball-cock, float and over-flow.
The entrances to the respective legs of the syphon are circumferentially surrounded
in common by a piston-like Hange suitable for working plunger-like within the well.
The tops or inner ends of the legs are open to one another, so that the water has
a free passage through the said legs to the open end of the stand pipe which is
located within the middle.
Figure of the accompanying drawing represents in longitudinal vertical section,
a water waste preventor flushing cistern constructed, arranged and provided with
imp made according to our invention.
2 represents a perspective view of the same with one of the sides broken
into, thereby showing the several parts of the cistern in elevation.
Figure 3 represents a vertical section of the three legged syphon and its
plunger-like bottom flange.
Figure is a cross section of the syphon upon the dotted line. Figure 3 looking
downwards.
Figure 5 is a topside plan of the combined plunger and syphon, and
Figure 6 is a horizontal section of Figure 1 upon the dotted lines .e', looking
downwards and showing the syphon in plan.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is a syphon, having triplicate legs or water passages a', a² and a³, surrounded
at their open and bottom ends by a plunger-like flange a', which is of the same
shape as, and works piston-like within, a slightly elevated well b, open at top at 65
and having holes, made within its closed bottom &, and also having a foot &', for
elevating the same resting upon the bottom c', of the flush box e, whose top edge c³,

page_text: is in a slightly lower plane than the open top d', of the standpipe d, passing through
the bottom of and made fast to the said flush box c, and over which the middle
leg a³, of the three legged syphon a, passes.
The said syphon is picked up by the gapped end e', terminating the branches of
the ends e', of a lever e, jointed at 2, to an extension of the flush box, and having
a stop e³, and a pull e'.
The said ends e, engage with trunnions a³, on the opposite sides of the syphon.
The whole of the legs a', a, a, are open to each other at their upper ends a³.
is the ball tap, the overflow and i the downpipe leading from the stand-pipe.
To operate the cistern, depress the lever by the pull, when the inner end of the
arm is lifted, and with it, the syphon is picked up and its flanged end taken towards
the top of the well. Assuming that the stand and down pipes are open to the pan
of the closet, water fills up the well and occupies the space vacated by the piston
and lower part of the syphon.
Now when the pull is released, the triple-legged syphon with plunger falls, and
forces a part of the water located below it in the well up both the outer legs and up
the clearances between the middle leg and stand-pipe, when the respective streams
of ascending water meet above and pass over the top of and flow down the said
stand-pipe, and the water thus ascending acting as a water piston, causes the initial
starting of the syphonic action, which is then continued in the ordinary way
consequent upon the standpipe, combined with the down-pipe, forming the longer
leg to the syphon system. The flow of water or syphonic draught is continued
until the cistern is empty.
The holes in the bottom of the well come opposite the open bottoms to the legs,
and in order to prevent the syphon from twisting, the said well and piston flanged
end may be made of a D-figure, or of the inside section of the well.
As a modification of our improvements, the initial starting of the flush may be
accomplished by depressing the three-legged syphon, that is, the normal position
of the syphon is "lifted," with the piston end coming near the mouth of the
well, when by pulling the lever through the pull, the syphon (which may be
counterpoised) then descends and forces the liquid up the legs and starts the
syphonic action of the cistern.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. In the syphons of flushing cisterns, making the same three-legged, with
the legs open to each other at their upper ends and with one of the legs or the
middle leg taking and working over the standpipe, substantially as described and
set forth.
Secondly. In the syphons of flushing cisterns, making the same three-legged as
referred to in the first claim and with a plunger or piston flange surrounding its
bottom edge, substantially as described and set forth.
Thirdly. In flushing cisterns, the combination with a three-legged and plunger-
flanged syphon, of a well, located within the flush box, and adapted to form a
cylinder for the plunger flange of the syphon to work within, substantially as
described and set forth.
Fourthly. In syphon flushing cisterns, the general construction, arrangement
and combination of the parts, substantially as and for the purpose herein described
and set forth.
