IMPROVEMENTS IN AUTOMATIC SUPPLY VALVES
Year: 1884

page_text: I, ALFRED CHRISTOPHER BELL of Bexley Heath in the County of Kent, Zinc
Worker and Plumber do hereby declare the nature of my said invention for
IMPROVEMENTS IN AUTOMATIC SUPPLY VALVES to be as follows:
This invention has reference to the Automatic Supply of water or other liquids
to vessels, and maintaining such water or other liquids at a constant level.
For this purpose I provide a hollow cylinder or vessel having an outlet at its
lower part and in the cover of which is fixed a vertical pipe projecting downwards
into the said hollow cylinder or vessel which is in communication with a main
supply pipe by means of connections in the usual manner. Up and down the
outside of the vertical pipe slides a float, an extension of, or an attachment to
which at its bottom part forms a perforated cage. Immediately below the
perforations a valve fitted with a suitable seating (preferably of india rubber or
other clastic material) is screwed on to the bottom of the cage. so that upon the
ascent of the float the said seating is brought against the lower end of the vertical
pipe. Thus, supposing the hollow cylinder or vessel to be empty and the float in
the lowest position the supply of water or other liquid would pass from the main
supply pipe, down the fixed vertical pipe, through the perforations in the cage, to
the interior of the hollow cylinder or vessel and through the bottom outlet of the
same to the vessel it is intended to supply, the float rising on the fixed vertical
pipe according as the water accumulates and until the valve seating is brought by
the action of the float to bear against the lower end of the fixed vertical pipe, thus
sbutting off the supply. The action of the float is governed by the level of the
liquid in the vessel or vessels supplied through the outlet at the lower part of the
hollow cylinder or vessel.
Instead of the main supply pipe and the fixed vertical pipe being connected to
the hollow cylinder or vessel at the cover the same connection may be effected at
any other suitable part.

page_text: I ALFRED CHRISTOPHER BELL of Bexley Heath in the county of Kent,
Zineworker and Plumber do hereby declare the nature of my invention for
IMPROVEMENTS IN AUTOMATIC SUPPLY VALVES. and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention has reference to the automatic supply of liquids into vessels such
as Kitchen range boilers &c and maintaining such liquids at constant levels.
For this purpose I provide a hollow vessel having an outlet at its lower part,
and in the upper part or cover of which is fixed a pipe projecting vertically, or
approximately so, downwards into the said vessel and being in communication
with a main supply pipe by means of connections in the usual manner. Up and
down the outside of the vertical pipe slides a float an extension of or an
attachment to the bottom part of which forms a perforated cage. Immediately
below the perforations a valve fitted with a suitable seating (preferably of india
rubber or other elastic material) is screwed on to the bottom of the cage, so that
upon the ascent of the float the said seating is brought against the lower end of
the vertical pipe. Thus supposing the hollow vessel to be empty and the float
in its lowest position the supply of water or other liquid would pass from the main
supply pipe down the fixed vertical pipe, through the perforations in the cage to
the interior of the hollow vessel and through the bottom outlet of the same, the
float rising on the fixed vertical pipe according as the liquid accumulates, and until
the valve seating is brought by the action of the float to bear against the lower
end of the fixed vertical pipe, thus shutting off the supply. The action of the float
is governed by the level of the liquid in the vessel or vessels supplied through the
outlet at the lower part of the hollow vessel.
Instead of the main supply pipe and the fixed vertical pipe being connected to
the hollow vessel at the cover the same communication may be effected at any
other part.
In the accompanying sheet of illustrative drawings Figs. 1 and 2 are sectional
elevations, Fig. 3 a plan, and Fig. 4 a sectional plan, of one form of apparatus
according to my invention.
A is the hollow vessel, B the outlet, C the cover, D the fixed vertical pipe,
E coupling to main supply pipe, F the float, G the perforated cage, H the valve
with elastic seating I.
The action of the apparatus is as follows:-Supposing the hollow vessel A to be
empty and the float Fin its lowest position as shewn, the supply of liquid would
pass from the main supply pipe, down the fixed vertical pipe D, and through the
perforations in the cage G to the interior of the hollow vessel A and through the
outlet B to the vessel it is intended to supply, the Hoat F rising on the fixed
vertical pipe D according as the liquid accumulates and until the valve seating I
is brought by the action of the float F to bear against the lower end of the fixed
vertical pipe.D, thus shutting off the supply.
It is obvious that the arrangement shewn may be considerably modified, for
instance, the liquid instead of passing through the perforations in the cage G may
pass through the annular space K in the centre of Hoat. F; Or the seating may be
placed on the top instead of the bottom of the float.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is;-
In Automatic supply valves, the arrangement of a float carrying carrying a valve
which, by the variation of level of the liquid in the containing vessel causes the

page_text: valve to open or close the end of a fixed pipe in connection with a main supply
pipe, and thereby to maintain the liquid in the vessel or vessels supplied at &
constant level, substantially as described and illustrated.
