STEPHEN ARNOLD PEARSON, 47, Park Green, Macclesfield, Accountant, do hereby
declare the nature of this invention for an automatic flushing arrangement to be as
follows:-
AA!
The arrangement to consist of a vessel with a valve fixed in the bottom, the
valve to be closed by a plug made of any material that will float, wood, india
rubber, metal ball, &c. The plug to be attached at the required distance to a
float. The float to be made of any material and shape that will float, 'and must
be of sufficient power to release the plug from the valve, and be suspended at the
required distance over the centre of the valve. The draw off pipes to be arranged to
prevent the suction overcoming the float, but yet of sufficient suction to draw the
plug into the valve when emptying. The arrangement works thus, when liquid
begins to flow into the vessel, the plug closes the valve and as the liquid rises the
tighter the plug fits, till the liquid reaches the float and as the liquid still rises the
power of the float is developed till it releases the plug which then rises to the top
of the liquid which at once flows away till the plug resumes its position in the
valve. When not required to work automatically the float not to be used but the
plug is then released by direct pull or lever which will then float to the top of
the liquid and resume its position as before.

STEPHEN ARNOLD PEARSON, 47, Park Green, Macclesfield, Accountant, 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:
The invention consists of a valve plug (1) made of any floating material which
when free from the valve will rise and float on the liquid and as the liquid runs
away will sink and be drawn by suction into the valve closing the outlet. To
release the plug (1) automatically a float (2) is suspended over the plug (1) and
attached (3) to it, and as the liquid rises gradually gives the float (2) sufficient
power to release the plug (1).

page_text: ILLUSTRATION OF THE WORKING :-
A valve half ball shape open at the bottom for outlet, is fixed in a vessel to contain
the liquid, the bottom of the vessel to slope gently from the sides to the valve.-
The plug (1) I am using is a hollow airtight india rubber ball made with a
projection to which an attachment (3) can be made.
The float (2) is a lacquered round tin air tight vessel flat top and bottom,
diameter and depth in accordance with the power required to lift the plug (1). At
the middle of the top and bottom is a brass projection to which attachments (3) are
made, the bottom to connect the plug (1) and float (2) and the top one to connect it to
the top of the vessel to hold it in suspension at the required distance above the
plug (1). When the liquid begins to run into the vessel the plug (1) is drawn by
suction into the valve and closes it, the liquid then begins to rise in the vessel till
it reaches the float (2), the float (2) is adjusted that its power is not sufficient to
remove the plug (1) as soon as the liquid reaches it, but the liquid continuing to rise
round the outside of the float (2) gradually increases its force till it releases the
plug (1) with a jerk sufficient to remove it out of the reach of the suction, the
plug (1) then immediately rising of itself to the top of the liquid, gradually sinking
as the liquid runs away till it again closes the outlet and thus continues to act as
the liquid flows into the vessel. The plug (1) may also be released from the valve
either by direct pull or by lever, the same action in the vessel by the plug (1)
going on.
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:
1. The novelty of a floating plug (1) which when released from the valve will
rise to the top of the liquid and fall as the liquid flows away till it closes the
valve again.
2. The novelty of a float (2) which when attached (3) to the plug (1) will release
the plug (1) when required.
3. The novelty of attaching (3) the float (2) and the plug (1) so that the float (2)
has power to release the plug (1), and does not interfere with its closing the
valve.
