PROVISIONAL SPECIFICATION.
Improvements relating to Apparatus for Storing and Expelling
Liquid under Pressure.
I, REGINALD HADDAN, of the firm of Herbert & Co., Patent Agents, of
18, Buckingham Street, Strand, W.C., London, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to
me from abroad by Julian Fagoaga y Azcona, of Pino 13, Barcelona, in the
Kingdom of Spain, Mechanical Engineer, to be as follows:-
This invention relates to apparatus in which water or other liquid may be stored
or placed under pressure and from which it may be expelled by said pressure when
desired, such apparatus being suitable for extinguishing fires, filling ships' water
tanks, or such other purpose for which a stream or jet of water under pressure is
required.
The improvements consist in providing the receiver in which the water is stored
with a suitable outlet controlled by a valve which when it is opened by hand is held
back from its seat thereafter by the rod of a float so that when the receiver is
emptied of water or liquid the float then falling releases the valve which is then
closed by a spring and the air pressure in the receiver is retained by the air being
prevented from escaping after the water or liquid has been expelled.
The rod of the float may also be connected by an elbow lever to that of the valve
so that the falling of the float rod closes the valve in place of releasing the
latter to be closed by the spring.
Dated this 26th day of April 1890.

COMPLETE SPECIFICATION.
Improvements relating to Apparatus for Storing and Expelling
Liquid under Pressure.
I, REGINALD HADDAN, of the firm of Herbert & Co., Patent Agents, of
18, Buckingham Street, Strand, W.C., London, Civil Engineer, do hereby declare
the nature of this invention, a cominunication to me from abroad by Julian Fagoaga
y Azcona, of Pino 13, Barcelona, in the Kingdom of Spain, Mechanical Engineer,
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 apparatus in which water or other liquid may be stored
or placed under pressure of compressed air and from which it may be expelled by
said pressure when desired, such apparatus being suitable for extinguishing fires,
filling ships water tanks or such other purpose for which a stream or jet of water
under pressure is required.
The improvements consist in providing the receiver in which the water is stored
with a suitable outlet controlled by a valve which, when it is opened by hand or
otherwise is held back from its seat thereafter by the action of a float so that when
the receiver is emptied of water or liquid, the float then falling causes or allows the
valve to be thereupon closed and the air pressure in the receiver to be retained by
the air being prevented from escaping after the water or liquid has been expelled."
Reference being made to the accompanying drawings,
Fig, is a longitudinal section of a water tank made in the form of a boiler and
provided with the contrivance for fulfilling the above mentioned purpose showing
the valve held open by the action of the float.

page_text: Fig. 2 is a similar view of part of the tank showing a modification in the mode of
connecting the float rod to the valve.
A is a closed tank having at a suitable place in the floor, being its lowest part a
pocket B. C is a pipe passing down through the roof of the tank and extending
down to within the pocket B. The pipe C extends above the tank and branches
laterally so that space is provided for the valve D which is pressed on its seat D
by spring E and may be opened or thrust back against the action of the spring by
any suitable kind of spindle or rod to be moved by hand. G is a float in the
pocket B, the rod H of this float extends up the pipe C to the head thereof. This
rod H carries the laterally extended projection Hand on the spindle of the valve D
is a pin D, this pin and the projection H¹ being relatively placed so that when the
valve is opened by hand, the float, lifted by the water, rises until the projection H¹
lies in the path of the pin D¹ and prevents the valve from closing until the water
having been all driven from the tank through the pipe C and outlet C¹ the float G
eventually falls just before the level of the water in the tank sinks to the edge of
the pipe C, and the projection H' passing down from before the pin D' the valve is
closed by the spring E and the compressed air in the tank A. is retained.
When the float rod H is connected directly to the valve D, this may be done as
in Fig. 2 by a bell crank lever J pivoted at J and connected at one end to the
float rod Hand at the other by a rod J' to the valve D. It being necessary here
to lift. the rod H to close the valve the float G operates the rod H through a
pivoted lever G connected at one end to the float and at the other to the rod H
instead of the float being directly fastened on the end of the rod so that the falling
of the float, lifts the rod. An additional valve K is here shown on the float
rod H.
•
The valve D in this modification is not moved by hand, but automatically follows
the movement of the float, being open when the float is raised and closed when the
float falls. To retain the water in the tank therefore any convenient form of stop
cock is placed in the pipe C¹..
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
The combination of a closed tank A adapted to receive water under pressure of
compressed air, a pipe C descending to near the bottom of said tank; a rod H
passing upward through said pipe, a float G connected to said rod and a valve D
in said pipe adapted to be closed simultaneously with the fall of said float for the
purpose set forth.
