IIILLARY II. TIALLEY AND ROBERT I. McCULLEY, OF STILES, TEXAS.
VALVE.
SPECIFICATION forming part of Letters Patent No. 574,540, dated January 5, 1897.
Application filed January 31, 1896, Berial Nc, 577,592, (No model.)To o.ll wheon it nacCy concern:I
Be it known that we, HILLARY H. HALLEY
and ROBERT I. MCCULLEY, citizens of the
United States, residing at Stiles, in the county
5 of Tom Green and State of Texas, have in-
vented a new and useful Valve, of which the
following is a specification.
Our invention relates to valves, and par-
ticularly to float-valves employed in connec-
ro tion with receptacles in which it is desirable
to retain the liquid, as water, at a uniform
depth, such as water-troughs for cattle, the
construction of the device being such as to
close the valve when the surface of the water
15 reaches the desired point and allow the valve
to open when the surface of the water falls
below said point.
The object of the invention is to provide
means whereby in case the float is disar-
20 ranged by the cattle the valve will be auto-
matically closed to prevent waste of water,
the disarrangement being such as not to per-
manently injure the valve mechanism or con-
nections.
25 Further objects and advantages of this in-
vention will appear in the following descrip-
tion, and the novel features thereof will be
particularly pointed out in the appended
claims.
30 In the drawings, Figure 1 is a sectional
view showing a trough or receptacle contain-
ing a valve mechanism embodying our in-
vention arranged in connection with an ele-
vated tank. Fig. 2 is a detail view, partly
35 in section, of the valve mechanism.
Similar numerals of reference indicate cor-
responding parts in all the figures of the draw-
ings.
I designates a receptacle in connection with
40 which the valve mechanism embodying our
invention is employed, said valve mechanism
comprising, essentially, a valve-casing 2 in
communication with a supply-pipe 3 and pro-
vided with upper and lower guides 4 and 5
45 for the stem 6 of the valve 7. Said guides
are formed in spiders 8 and 9, respectively,
the upper spider S being formed integral with
a cap 10, having a central outlet-opening 11,
through which the liquid escapes from the
50 interior of the casing. The valve-seat 12 is
formed around said outlet-opening, and in
the construction illustrated consists of an an-nular cushion of suitable yielding or elastic
material, such as rubber or leather. The
valve 1 is preferably of conical form, whereby 55
the water or other liquid entering through
the supply-pipe 3 is deflected by the beveled
under surface thereof to avoid the closing of
the valve until relieved of the weight of the
float. 60
Secured to the upper end of the valve-stem
is an approximately semispherical cup 13, in
which is seated a spherical head 14 on the
lower end of the float-stem 15. This float-
stem is coupled, bymeans of the union 16, to 65
a projection 17 on the head 14, and is also
coupled, by means of a union 18, to a pro-
jection 10 on the spherical float 20. The
float is provided at a point opposite the pro-
jection 10 with an eye 21, to which are at- 70
tached the inner ends of limiting orguy wires
22, said wires being preferably attached at
their outer ends to the sides of the receptacle
by means of staples 23. In case of attack by
cattle the wires 22 will be encountered, and 75
the vibration of the float caused thereby will
dismount the head 14 from the cup 13.
The weight of the float is sufficient when
the level of the water is lowered to unseat
the valve, but when the weight of the float So
is removed from the valve the pressure of the
water within the valve-casing is sufficient to.
seat the valve irrespective of the level of the
water in the receptacle. Hence in case of in-
jury to the means employed for protecting 85
the valve mechanism the valve will be auto-
matically seated to prevent the escape and
waste of water which would result if the valve
were allowed to remain open.
In Fig. 1 we have shown the receptacle in 90
communication, through the improved valve
and the supply-pipe 3, with an elevated tank
24, this being a common arrangement of de-
vices employed for supplying cattle contin-
uously with water. 95
Various changes in the form, proportion,
and the minor details of construction may be
resorted to without departing from the spirit
or sacrificing any of the advantages of this
invention.
Having described our invention, what we
claim is-
1. The combination of a valve adapted to
be seated by internal pressure in the valve-
