PROVISIONAL SPECIFICATION.
Improvements in Syphon Cisterns.
I, WALTER STOCK, of the firm of Stock, Sons, & Taylors, of 35, Temple Street
Birmingham, in the County of Warwick, Brassfounders, do hereby declare the nature
of this invention to be as follows:-
This invention consists of an improved syphon action for cisterns whereby a
saving of water is effected and waste prevented.
. The stand or supply pipe which passes through the cistern is brought up to the
same height or level with the top of the cistern and fitting over the stand pipe is
an inner and outer "bell" or dome the inner bell encasing the stand pipe, the inner
bell is connected to the outer bell by means of rivets or in any other suitable
mauner. A chamber or well is situated at the bottom of the cistern round the stand
pipe and the bell or dome fits down over this bell.
Upon the upper part of the outer bell on each side are snugs or projections and a
lever raises and lowers this bell or dome. This lever takes its bearing upon the
sides of the cistern by means of a cross piece or axle which lodges in slots cut out
for the purpose, the lever has two arms which catch or hook under the snugs or
projections upon the bell.
The usual chain may be attached to the end of the lever to actuate the same to
cause a flush of water, and obviously by drawing down the chain the lever is
depressed the bell or dome thereby raised a certain height and the water is forced
from the bell or inner chamber over the top of the standpipe and into the same.

COMPLETE SPECIFICATION.
Improvements in Syphon Cisterns.
I, WALTER STOCK, of the firm of Stock, Sons, & Taylors, of 35 Temple Street,
Birmingham, in the County of Warwick, Brassfounders, 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, reference
being had to the drawings hereunto annexed, and to the letters & figures shewn
thereon :-
This invention has for its object an improved method of syphon action for cisterns
with a view of obtaining a simple yet effective means whereby a saving of water is
effected waste prevented and yet a good supply delivered down thro' the pipes for
the purpose of flushing and thoroughly washing out the basins of w.c.'s urinals
and such similar situations where the apparatus may be fixed and where a flow and
flush of water may be required.
I will describe my invention more fully by the aid of the annexed drawings in
which
Figs. 1 and 2 are sectional elevations of my improved syphon cistern.
Fig. 3 shews a top view of the bell or dome and the kind of lever I usually
employ although other kinds may be used.
When the cistern or tank is full or at high water level the different parts will
assume the positions seen in Fig. 2.
On the other hand when at low level the different parts will be seen as in Fig. 1.
A is the cistern or tank, B is the stand pipe rising through the cistern to
P71

page_text: higher level than usual for the purpose hereinafter described. B' is the supply
pipe extending from the bottom of the cistern A and in direct connection with
the stand pipe 13 and forming a continuation of same for the water to flow
down, D is a double bell or dome and consisting of an outer and inner bell,
the inner bell is rivetted or attached to the outer bell or domo D in any
suitable manner us at E and is of sufficient diameter to pass down over and
encase the stand pipe B, this inner bell has a flanged termination or footing all
round CF is a well or circular chamber surrounding the base of the stand
pipe 13 within which well the flanged footing of the inner bell descends.
G, Gis the ordinary inlet valve and Hoat of the kind commonly known as
ball valves for regulating the supply of water to the cistern. H is an inlet pipe
and an outlet or overflow. Jare the songs or projections upon the neck or
upper part of the outer bell or dome on opposite sides thereon. K is a lever
for lifting the bell or dome having a cross bar or axle L. and terminating with
two arms of a spur shape M see Fig. 3, the cross bar or axle obtains a bearing
upon the sides of the cistern or tank which have seatings or slots cut therein
to receive same, the usual button will be upon the one end of the cross bar working
against a fixed stop upon the cistern side.
A handle and chain N or other suitable method for depressing the lever is
affixed thereto.
In order to create a flush of water for the swilling out of a w.c. or urinal
basin and the like.
By pulling down the handle and chain N, or actuating other suitable lever con-
nection for the depression of same, the lever K is thereby depressed at its one end,
thus raising the bell or dome D and inner bell ('n certain height as seen in Fig. 1,
this action causes a vacuum to be formed in the double bell the water meanwhile
Howing into the bell at the base of the stand pipe, the sides of which bell are out
out on the top edge at intervals to allow of a quicker supply thereto.
By releasing the handle and chain or other attachment the bell or dome is
depressed to the first position Fig. 2. The pressure brought to bear upon the
quantity of water within the well by the downward action of the double bell and
the compressed air within such hell, forces up a given quantity of water from the
well through the intervening chambers (a) (a) between the outer and inner bell
and the inner bell and the stand pipe, the amount of pressure thus produced forcing
the water sufficiently high for it to flow over the top of and down the stand pipe B
and thus flowing into the supply pipe B' is conducted to the w.c. or urinal basin
as the case may be and effectually flushes and cleanses the same.
The cistern or tank will supply itself as in the usual manner after each discharge
or flush of water (this supply being governed by the ball valve), but in the event of
the ball valve becoming out of order, one object of my invention comes into effect,
ris, that by prolonging or carrying the stand pipe to a height nearly level with
the sides of the cistern or tank, the water instead of flowing to waste down the
stand pipe will force its way through the slots or seatings in the sides of the cistern
or tank which carry the lever thus indicating that something is wrong, hence water
waste is prevented.
I wish to be understood that. I do not confine myself to the precise details herein
as may modify the different parts required to construct my improved method.
I may mention that the cistern or tank will be covered in, in the usual manner,
with a covering or lid the same being somewhat hollowed or expanded over the
bell or done to allow for the rising of the same when being operated.
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 cistern the combination of the various parts as shown, in the
building up of the said syphon cistern and the particular formation of such parts
tovether with their manner of working whereby the waising and lowveising of a

page_text: double bell or dome forces the water up the interior of the double bell or dome
over the top of and down the stand pipe and thereby causes a flush of water for
purifying and cleansing the basins of w.c.'s urinals and such like, substantially as
herein set forth and described.
Second. I claim in a syphon cistern, the improvements for flushing w.c.'s,
urinals and the like by the means and in the manner hereinbefore described and
shewn whereby any waste of water is prevented and a simple yet effective syphon
flushing action is obtained as set forth."
