WILLIAM WHITE, of 30ª, Wimpole Street, in the County of Middlesex, Architect.
IMPROVED MECHANICAL ARRANGEMENTS TO BE APPLIED TO BALL, FLOAT, AND
OTHER VALVES FOR FACILITATING THE ACTION THEREOF."
The principle of the action of this valvo is mainly automatic, the pressure of the
column of water behind it being alone sufficient to close it immediately upon the
release of the valve without any leverage.
The valve may be clack or spindle, and its opening motion will be against the
inlet current of water by means of a lever from below or outside of the water way.
In the case of high pressure I purpose to open the valve by means of a strong bar
lever, which is raised or lowered by a ball float lever attached. This bar lever
may be loaded by the addition of weights or otherwise for the purpose of regulating
its action as a counterpoise to the column of water to any such extent as shall still
be within the power of the ball float to raise. And in order to meet the case of
extraordinary pressures an intermediate lever bar may be introduced between the
bar lever and the ball float.
In cases of low pressure where the weight of water is no greater than may be
readily over balanced by a simple ball float the lever bar is not required, though I
reserve liberty to use it as well as the simple ball float alone, and I purpose to
make this principle applicable to a similar automatic closing of water-way_taps
without the ball Boat for other purposes of water arrangements generally: These
last mentioned arrangements will be found useful for actuation by manual or other
power.

WILLIAM WHITE, of 30, Wimpole Street, in the County of Middlesex, Architect.
"IMPROVED MECHANICAL ARRANGEMENTS TO BE APPLIED TO BALL, FLOAT, AND
OTHER VALVES FOR FACILITATING THE ACTION THEREOF.'
The principle of the action of this valve is mainly automatic, the pressure of the
column of water behind it being alone sufficient to close it without any leverago
immediately upon the release of the valve.
The valve may be clack or spindle, and its opening motion will be against the
inlet current of water by means of a lever from below or outside of the waterway.
In the case of high pressure I purpose to open the valve by means of a strong
bar lever, which is raised or lowered by a ball float lever attached.
This bar lever may be loaded by the addition of weights or otherwise for the
purpose of regulating its action as a counterpoise to the column of water to any
such extent as shall still be within the power of the ball float to raise.
And in order to meet the case of extraordinary pressures an intermediate lever
bar may be introduced between the bar lever and the ball float.
In cases of low pressure where the weight of water is no greater than may be
readily overbalanced by a simple ball float the lever bar is not required, though I
reserve liberty to uso it as well as the simple ball float alone, and I purpose to make
this principle applicable to a similar automatic closing of water way taps without
the ball float for other purposes of water arrangements generally. These last
mentioned arrangements will be found useful for actuation by manual or other
power.
Having thus far described the nature of the said Invention, and incidentally
intimated in what manner the same is to be performed, I will now proceed (aidod
by the accompanying Drawings) to further and particularly describe and ascertain
in what manner the same is to be performed or carried out in practice, that is to

is ground in to stop formed against the box b when the valve v is raised. The
stuffing & is to provide against the leakage only of the few drops which might
otherwise take place during the action of the screw (s, c,) which passes through it.
i, inlet; o, outlet.
Having now particularly described and ascertained the nature and object of the
said Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the Invention of "Improved Mechanical
Arrangements to be applied to Ball, Float, and other Valves for Facilitating the
Action thereof," substantially as herein before set forth and described, it being
understood that the principal and important point in the said Invention is the
construction of such valves, as above mentioned, so as to open wholly with force
applied below and external to the waterway by action of direct counterpoise to the
column of water within, and which by the weight thereof automatically close, and
without stuffing or packing, whether by grinding in or otherwise of the operating
medium.
In witness whereof, I, the said William White, have hereunto set my hand
and seal, this Second day of June, in the year of our Lord One thousand
sight hundred and sichty
