PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Controlling Supply of Water or
other Liquid.
I, HENRY FAIJA, of No. Great Queen Street, in the City of Westminster,
Civil Engineer, do hereby declare the nature of this invention to be as follows:--
With ball cock apparatus as usually arranged to control the supply of water to
cisterns as for example to the water waste preventing cisterns of water-closets and
for other uses the closing of the cock is effected gradually the ball being raised as
the water level in the cistern rises. It results that the quantity being supplied to
the cistern is constantly and gradually diminishing until the flow becomes very
small. Consequently much more time is occupied in filling the cistern than would
be needful if the water way through the cock remained wide open until the cistern
was nearly full.
Now the object of my invention is to obviate the disadvantage referred to for
which purpose I provide a separate compartment or chamber for the ball and in
connection with this compartment or chamber I arrange a syphon whose longer
leg terminates at any desired level within the cistern. The shorter leg is provided
at a point above its lower end with an air escape hole and with some means to
prevent entrance of air into the syphon through the said hole during the emptying
of the syphon, the arrangement being such that when water is flowing through the
cock into the cistern the ball will remain unaffected until the water level in the
cistern rises to and above the bend of the syphon whereupon water will flow also
into the compartment or chamber containing the ball which will thus be caused to
rise and close the cock; as the cistern is emptied the water will be, withdrawn by
the syphon from the ball compartment or chamber and the ball will descend
therein thus again opening the cock and so on. In one arrangement the air escape
bole is furnished with a cup or vessel that is filled with water from the ball chamber
so that whilst water is being withdrawn through the syphon as above described the
air hole will remain sealed but that it will be subsequently unsealed by the
continued escape of the water from the cup or vessel.
As will be evident apparatus according to my invention can be constructed in
various forms and adapted to control the supply of liquid for other purposes than
the flushing of water-closets.

Improvements in Apparatus for Controlling :Supply of Water or
other Liquid.
:
I, HENRY FAIJA of No. 2 Great Queen Street, in the City of Westminster,
Civil 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 :—
:
"
With ball cock apparatus as usually arranged to control the supply of water so
isterns, as for example to the water waste preventing cisterns of water closets, and
for other uses, the closing of the cock is effected gradually, the ball being raised as
the water level in the cistern rises. It results that the quantity being supplied to

page_text: the cistern is constantly and gradually diminishing until the flow becomes very
small; consequently much more time is occupied in filling the cistern than would
be needful if the water way through the cock remained wide open until the cistern
was nearly full.
Now the object of my invention is to obviate the disadvantage referred to, for
which purpose I provide a separate compartment or chamber for the ball, and in
connection with this compartment or chamber I arrange a syphon, whose longer
leg terminates at any desired level within the cistern. The shorter leg is
provided at a point above its lower end with an air escape hole, and with some
means to prevent entrance of air into the syphon through the said hole, during the
emptying of the syphon, the arrangement being such that when water is flowing
through the -cock into the cistern the ball will remain unaffected until the water
level in the cistern rises to and above the bend of the syphon, whereupon water
will flow also into the-compartment or chamber containing the ball, which will thus
be caused to rise and close the cock; as the cistern is emptied, the water will be
withdrawn by the.syphon from the ball compartment or chamber, and the ball will
descend therein thus- again opening the cock and so on. In one arrangement the
air escape hole is furnished with a cup or vessel that is filled with. water from the
ball chamber, so that whilst water is being withdrawn through the syphon as above
described, the air hole will remain sealed, but that it will be subsequently unsealed
by the continued escape of the water from the cup or vessel.
As will be evident apparatus according to my invention can be constructed in
various forms, and adapted to control the supply of liquid for other purposes than
the flushing of water-closets.
In the accompanying drawings, wherein the same letters of reference, so far as
they are used in different views, are there applied to like parts in each case,
Fig. 1. is a sectional elevation showing the general arrangement of my invention,
and one means which I adopt for opening and closing the air escape hole.
Fig. 2. is also a sectional elevation showing another arrangement of opening and
closing the air escape hole.
Fig. 3. is a transverse section at X. Y. of the arrangement shown in Fig. 2.
In Fig. 1. A, is a portion of the cistern or tank into which it is desired to
regulate the flow of water or other liquid, and B. is a separate vessel which may
be placed either inside or outside the tank A, in which the ball G, rises-and falls,
actuating the tap C, by which the cistern A, is filled.
D, is a syphon by which the water or liquid is drawn cut of B, into the cistern A.
E, is an air escape hole surrounded by the open vessel F.
The action of the apparatus may be thus described. The cistern A, being
empty, the vessel B, will also be empty, or nearly so, and the ball will be in the
position shown by the dotted lines; the tap C, will be open and consequently the
cistern A, will be filling gradually, but no liquid will flow into B, until such time
as the liquid or water in A, has reached to abont, or above, the top of the syphon D,
and until this desired level is. reached the tap C, will be full open; when the liquid
has reached this level .however it will commence to flow through the syphon I),
which in this instance acts only as a conduit, quickly filling the vessel B, which is
of small relative capacity, and thus, the ball G, will be raised and the tap C, closed,
when also the vessel F, surrounding the air escape hole E, will be filled. As the
cistern A, is emptied the vessel B, will remain full, and the tap C, therefore closed,
until such time as there is sufficient difference in the level of the water or liquid in
the two vessels for the syphon to start, and as the vessel F, will then be full of
water, the air escape hole E, will be sealed, and consequently the vessel B, will.be
emptied to any desired level below it, as for instance to the dotted line N. The
vessel F, which may be emptied by the air escape hole E, or by perforations in its
lower portion, or by both, will by this time.be empty, and the air escape hole,E,
unsealed. As the cistern A, fills the water or liquid rises in the longer leg of the
syphon D, and the air in the syphon is forced out through the air escape hole Ę
thus allowing of the flow of liquid from the vessel.A, into B, to commence wher

page_text: the desired level in A, has been reached, which flow will continue until B, is full
and the tap C, closed as already described.
In Figs. 3, and 4, I show a mechanical arrangement for opening and closing the
air escape hole E. H, is a valve fixed on the spindle I, running in guides and
attached to the lever K, working on the fulcrum L. The valve H, is adjusted to
remain on its seating, and keep the air escape hole E, closed, until such time as
owing to the liquid in B, falling, the ball comes down and the arm M, of the ball
valve presses on the end of the lever K, thus raising the valve H, off its seating to
about the position shown in dotted lines H¹, Fig. 3, and keeping the air escape hole
open so long as the ball G, remains in this, its lowest position. As the liquid flows
into B, the ball G, rises, and the lever K, is released from the pressure of the ball
arm M, when the valve H, will fall into its seating, and the air escape hole E,
be closed.
In conclusion I wish it to be understood that I do not limit myself to the precise
details herein before described and illustrated, as many modifications and variations
may be readily adapted, and the position of the air escape hole varied without
affecting the principle of my invention.
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: An arrangement substantially as shown for automatically regulating the flow
of water or other liquid by which the tap or valve filling the cistern or tank is
kept full open until such time as the water or liquid has attained the required
height in the cistern, and then rapidly closed.
2. In combination with a cistern or tank a separate vessel in which the ball
actuating the tap or valve, rises and falls, which vessel is emptied and filled by
means of a syphon communicating with the cistern or tank; the syphon being
provided with an air escape hole, which may be opened and closed as desired
substantially for the purposes hereinbefore described.
Dated this 10th day of June 1892.
