An Improved Bell Syphon Valve, applicable to Flushing and
Filtering.
I WILLIAM BARBER PRESS of 5 Lansdown Villas High Road Leytonstone in
the County of Essex Mechanical Model Maker do hereby declare the nature of
this invention to be as follows:-
My invention relates to outlet valves of flushing or other tanks or cisterns and
has for its object combining the simplicity of the common valve with the force of
the syphon, to give a reliable flush from the flushing cistern or a steady force from
the house supply tank or cistern when fixed therein, the constructing an outlet of
such a form that a perfect strainer or filtering arrangement can be readily attached
without interfereing with or preventing the free action of the said syphon valve by
this means strained or filtered water is supplied for use the fittings are not spoiled
with dirt or grit, and the bell or syphon valve being free should the pipes burst
with frost or the supply fittings require repair, the flow of water or other liquid
can be stopped. And my invention consists of a bell syphon valve constructed as
hereafter explained I fix in a tank or cistern for water or other liquids a stand pipe
or tube of any desired length (under water level) the base of which is flanged and
screwed for the convenience of and to which the outlet pipe is attached and can be
called the long leg, the top of the said stand pipe is turned true for a valve seat and
on which the valve leather or rubber rests when closed over the long leg or stand
pipe I place a bell of such a length that it shall reach near but not touch the
bottom of the cistern and of such diameter proportioned with outlet tube or long
leg that it shall form a complete syphon the said bell is provided with internal
projecting guides for the purpose of keeping it central the said guides are preferably
cast with the bell, over the guides and at the top of the bell inside I form a special
cavity for the reception of the valve plate the valve plate is centered therein having
an universal movement a leather or rubber pad is then placed against the plate and
kept in position by the bell guides that project beyond the valves diameter and thus
prevent the pad from falling, now it will be understood that the valve being
allowed to move in any direction it will readily accomodate itself to its seat and
would not be shifted by the sway of the bell or by irregularities in fixing the
cistern or tank, and that when the bell is down the valve is closed but when lifted
o its required higth syphonic action takes place and a perfect flush ensues when
used as a constant outlet from a tank or cistern for house or other supply. I
preferably keep the valve raised from its seat to a given higth by means of a
counterbalance weight preferably cast onto a lever the said lever being pivotted
n or into a fixed stand post or support raised above the highest point of the bell
he lever having a hook or eye is linked to the bell and the weighted end raises
he bell and keeps the valve off its seat the weighted end is, then coupled by link
r chain to the pull lever the pull lever being pivoted at any convenient part on
he cistern-to provide for fixing the strainer or filter I cast near the flange of the
tandpipe a rib to hold a rubber ring. Outside the bell is a similar rib my strainer
r filter can be of any approved material in the body with two necks formed of
liable material one fitting the standpipe the other the bell both are secured by
abber rings (preferably) but they can be screwed at base.

An Improved Bell Syphon Valve, applicable to Flushing and
Filtering.
I, WILLIAM BARBER PRESS, of 5 Lansdown Villa, High Road, Leytonstone,
Essex, Model Maker, 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 my invention relates to certain new and useful improvements in valves
more especially applicable for use in connection with flushing cisterns, and house-
supply-tanks; the object of the invention being, firstly, to provide a valve in which
the valve proper always effects a more perfect joint with the valve-seat than in
those valves usually employed and secondly, to provide simple and effective means
whereby the water passing through the valve for house supply can be effectively
filtered.
:
I now proceed to describe my said invention, reference being had to the
accompanying drawing and to the figures and letters of reference marked thereon ;
like letters referring to like parts throughout all the views.
Fig. 1., is a sectional view of a tank shewing my invention arranged therein.
Fig. 2., is a sectional elevation of my improved valve; and Fig. 3 is a plan of
the underside of the bell portion thereof.
Fig. 4., represents respectively an elevation and plan of the metal portion of the
valve proper.
Fig. 5., is a plan and elevation respectively of the rubber or other flexible disc
forming a part of the valve proper.
Fig. 6., is a detail view shewing my improved valve and filter combined.
A represents a water tank, with my improved flushing apparatus and valve
arranged therein. The flushing apparatus comprises the ordinary syphon-tube B-
secured in the tank in any desired manner, and having the branch-pipe C; the top
edge D thereof being made as true as possible. An inverted bell-shaped cap or
cup E-having inward radial extending ribs F is formed with a recess. G in which
is a smaller recess H. Within the recesses G, H, is fitted the valve proper I.
Said valve comprises a metal disc J, having a projection K, and a rubber or other
flexible disc or ring L upon which the part J rests.
The valve I is entered into
the recesses G, H edgewise; but when flat, as shewn in Fig. 2.,-it rests upon
and is retained in position by the ribs F. It will be readily understood that inas-
much as the valve is free to move in any direction, it will readily adapt itself to
any slight uneveness of the valve-seat D.
A projecting pin M is cast integral with and between the bend of the syphon-
pipes B and serves to support the rocking-lever N having arms O, P; from the
former of which the pull-chain Q depends, and from the latter a connection extends
to the cap E.
In operation, the water contained by the cistern A will enter the branch-pipe C
under the valve I when the chain Q is drawn downwards and the cap or cup E is
correspondingly raised. When, however the chain Q is released, the stream of
water through the syphon to the outlet-pipe R will continue until the tank is
empty.
When my improved valve is used in connection with house-supply cisterns and
in combination with my improved filtering device, I dispense with the syphon B
and form the valve-seat on the upper end of the outlet-pipe R (Fig. 6). A groove
or shoulder S is formed around the the inverted cup E to receive a flexible disc or
washer T a similar disc U being fitted around the pipe R. Any suitable filtering
medium, such as asbestos or other material or substance V extends between the
discs T, U, and strains all water entering the valve. The washer T being flexible
enables the cup E to be readily raised or lowered. A lever W is arranged above

page_text: the tank A. and has one end connected to the cup E and a weight X depending
from a flexible connection Y, secured to the other end. When it is desired to cut
off the flow of water through the pipe R, the weight X can be supported by a
hook or shelf Z, which enables the valve to shut off the water when the cup E
falls.
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 ==
1. In a flushing apparatus, the valve consisting of an inverted cup having radial
inward projections, a recess formed in the cup above the projections, a smaller
recess formed centrally in the firstnamed recess, a valve loosely contained within
the said recesses, and said valve consisting of a metal disc having a central upward
projection and a flexible and preferably soft disc resting against the under surface
of said metal disc, all substantially as and for the purposes herein before set forth.
2. In a syphon flushing apparatus the lever N pivoted to and supported by the
syphon B independent of the cistern, all substantially as herein before set forth.
3. The combination with a valve as hereinbefore described of a filtering device
consisting of a flexible disc arranged in an annular groove or upon a shoulder on
the inverted cup, a similar disc fitted to the outlet-pipe, and a filtering medium
arranged between the two discs aforesaid, all substantially as and for the purposes
hereinbefore set forth.
4. The combination with a water supply tank and a valve within the tank, of a
lever pivoted above the tank; one end thereof being connected to the tank, and a
weight depending from the other end, and means for supporting the weight when
desired to cut off the water supply, all substantially as hereinbefore set forth.
5. The hereindescribed valve, consisting of an inverted cup having inwardly
radial projections, a recess formed above said projections, a smaller recess extending
centrally out of the aforesaid recess, a valve proper loosely fitted within the
aforesaid recesses and retained therein by the radial inwardly extending projections
aforesaid, all substantially as and for the purposes hereinbefore set forth.
