Street, Rochdale aforesaid, Traveller, and GRINDROD KERSHAW, of 64, Clement
Royds Street, Rochdale aforesaid, Draughtsman, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to improvements in valves for automatically opening
and shutting off a supply of water or other liquid.
Our improved valve consists of a delivery pipe preferably with a conical mouth,
the large end being at the bottom; a spindle with a conical boss to fit the conical
mouth is fitted in this pipe, and the end of this spindle rests upon a lever ful-
crumed on a stationary bracket near the valve spindle and secured at its other
end to a float, which floats upon water in a vessel supplied through the valve,
the level of the water in the vessel automatically controlling the opening and
closing of the valve.
In applying our improved valve to maintain an uniform level of water say in
the conditioning trough of a warping and beaming machine, we form a well say
with the trough, and in this well place the float to control the supply of water;
when there is sufficient water in the trough the float and lever hold up tho
spindle and shut off the water, but when the level of water falls in the trough
and well, the float, in falling, moves the lever sufficiently to open the valve and
admit some water to the trough, and when the latter is full enough the float will
be lifted high enough to shut the valve again.
We prefer to employ the conical valve as described but any other suitable form
of valve might be employed and if desirable, a rubber or other soft or suitable
material might be placed between the valve and the plug.
We have only described our improved valve as applied to a warping and beam-
ing machine but it is obvious that a valve arranged as described inay be applied
for other purposes.

Improvements in Valves.
We, FRANK ASHWORTH HOLT, of Atlas Iron Works, Molesworth Street, Roch-
dale, in the County of Lancaster, Machine Maker, ALFRED SEELEY, of 34, South
Street, Rochdale aforesaid, Traveller, and GRENDROD KERSHAW, of 64, Clement
Royds Street, Rochdale aforesaid, Draughtsman, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
Our invention relates to improvements in valves for automatically opening
and shutting off a supply of water or other liquid.
Our improved valve consists of a delivery pipe preferably with a conical mouth,
the large end being at the bottom; a spindle with a conical boss to fit the conical
mouth is fitted in this pipe, and the end of this spindle rests upon a lever ful-
crumed on a stationary bracket near the valve spindle and secured at its other
end to a float, which floats upon water in a vessel supplied through the valve,
the level of the water in the vessel automatically controlling the opening and
closing of the valve.
In the accompanying sheet of drawings-
Figure 1 is a side sectional elevation. Figure 2 is an end sectional elevation
and Figure 3 is a plan of our improved float valve for automatically controlling
the supply of water or other liquid.
In these views, a designates a tank or well, b a bracket secured to the upper
sides of the tank, can adjustable supply pipe which passes freely through a
hole in the bracket b and is set and secured at the desired height by locknuts d;
e is a boss fixed to the end of the supply pipe and in this boss is formed the
seating for the conical valve f which is preferably faced with india rubber or other
suitable material and is carried by a valve spindle g. The lower end of the
valve spindle g is coned or pointed where it rests upon the flat surface ¹ of a
lever which is fulcrumed at i to a stationary bracket fixed to the end of the
tank.
The other end of the lever h has float attached to it and when the liquid
in the tank is at its normal level the valve is closed by the lever but when the
liquid is below its normal level and the float falls, the lever allows the valve to
open and liquid from the supply pipe c to flow into the tank until the normal
level is regained.
In applying our improved valve to maintain an uniform level of water say in
the conditioning trough of a warping and beaming machine we place the tank
at a suitable level and connect the tank by a pipe k to the trough so that the
float will act to regulate the valve and maintain the water at the same level in
the trough as it is in the tank, and if required we can vary the depth by adjust-
ing the position of the supply pipe c and so raising or lowering the valve.
Instead of employing a separate tank a and connecting pipe k we may place
the valve in a well forming a continuation of the trough.
We prefer to employ the conical valve as described and illustrated but any
other suitable form of valve might be employed.
We have only described our improved valve as applied to a warping and beam-
ing machine but it is obvious that a valve arranged as described may be applied
for other purposes.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is;-
-
1. In combination, the vertically adjustable supply nine having on external

page_text: valve seating at its lower end, and a valve, the spindle of which projects
upwardly into the supply pipe, and its lower end rests upon a float, lever by
which the valve is automatically closed or allowed to open as the level of liquid
varies, all substantially as herein set forth.
2. In combination, the tank a, supporting bracket b, adjustable supply pipe c,
locknuts d, boss e, having the external valve seating, valve f, spindle y, and
float lever h, all substantially as herein set forth.
Dated this 26th day of June 1900.
