HENRY S. PINKERTON, OF JUNO, TEXAS.
VALVE.
No. 840,954.
To all whom1 it 7Tamy concern:
Be it known that I, HENRY S. PINKERTON,
a citizen of the United States, residing at
Juno, in the county of Valverde and State of
5 Texas, have invented new and useful Im-
provements in Valves, of which the following
is a specification.
My invention has relation to valves, and is
designed as an improvement on Letters Pat-
o ent granted to me April 25, 1905, and num-
bered 788,426; and the invention consists of
the features of construction, combination,
and arrangement of parts hereinafter fully
described and claimed, reference being had
15 to the accompanying drawings, in which--
Figure 1 is a view in side elevation of a
float-valve embodying my invention. Fig. 2
is a vertical section through the same, taken
on a line parallel with the float-lever. Fig.
20 3 is a vertical transverse section taken on a
line centrally through the valve, the operat-
ing-lever, and the controlling-link connected
with the lever. Fig. 4 is a sectional plan
view taken on the line 4 4 of Fig. 2. Fig. 5 is
25 a view similar to Fig. 1, showing a modifica-
tion i1i the construction and mode of mount-
ing the operating-lever.
Referring now more particularly to Figs. 1
to 4, inclusive, of the drawings, the numeral
30 1 represents a base provided in its under side
with a threaded socket 2 to receive the
threaded end of a supply-pipe. Communi-
cating with this socket is a valve port or
opening 3, opening at its upper end through
35 the top of the base. The base is provided on
its upper side with an annular rim 4, sur-
rounding the opening 3 and forming a seat
for the reception of the valve proper, 5, which
comprises a disk or h ead 6, carrying upon its
4o under side a packing ring or gasket 7, adapt-
ed to engage the rim 4, said ring or gasket be-
ing secured to the disk by a cap-piece 8, hav-
ing a hollow body portion fitting within the
opening in the packing-ring, and a surround-
45 ing rim-flange 9, which projects beneath the
packing-ring and clamps the same firmly in
position against the under side of the disk or
head 6. A screw or other like fastening 10
passes through the hollow body portion of the
5o crown of the cap-piece and detachably se-
cures the same to the disk or head 6.
Rising from the base 1 is a supporting and
guide frame in the form of a double yoke,
said frame being composed of opposite sets
55 of standards 11 and 12, arranged upon dia-
metrically opposite sides of the port 3, said
Patented Jan. 8, 1907.
standards being ..connected at their upper
ends by cross-pieces 13 and an intermediate
web or top.piece 14. The standards 11 and
12 are arranged to form diametrically oppo- 60
site guide slots or passages to receive guide
ears or lugs 15, projecting from diametrically
opposite sides of the valve body or head 6,
whereby the valve is guided in a true vertical
path and held from oscillation. Secured to 65
the boss 18 is a guide-stem 16, which fits and
slides at its upper end in a guide-opening 17
in the top piece 14. This stem may. be
formed integrally at its lower end with the
boss 18, but is here shown in threaded en- 70
gagement with a socket formed in the boss
18, integral with the upper surface of the disk
6. This stem obviates any tendency of the
valve to tilt or cant during its opening and
closing movement. 75
The disk 6 is provided at one side of the
boss 18 with spaced flanges or ears 19, receiv-
ing a bolt 20, to which the inner end of an
operating-lever 21 is pivoted, which lever
carries at its outer end a float 22. The body 8o
.portion of the lever extends horizontally out
through the space between the- standards 12
and is provided at its inner end with a right-
angularly-bent arm 23, which is pivotally
connected at its lower free end with the bolt 85
20. The upper end of the arm 23 is pivoted
by a bolt 24 to the lower end of a slotted sus-
pension-link 25, pivoted at its upper end by a
bolt 26 to the horizontal connecting pieces or
members 13 of the yoke-frame. When the 90
valve is seated, the link 25 hangs vertically in
the plane of the arm 23 and opposes a resist-
ance to the upward movement of the valve,
and thereby serves, in effect, as a lock to hold
the valve closed against any tendency of the 95
water to lift it. When the lever 21 is oper-
ated, however, as by the downward move-
ment of the float 22, the lever will swing upon
the link and draw the latter laterally out-
ward, thus disposing it so as to offer the least oo
resistance to the upward movement of the
valve, which will thereby be permitted to
rise to its fullest extent without resistance
and to open wide the port 3 for the free out-
flow of water. 105
It will be observed that the standards 12
are offset at their upper ends, as indicated at
12', this offset portion serving to form a
wider support and brace for the lever and
permit the pivotal connections of the link io
and lever to have free and unobstructed out-
ward movement. The lower ends of both
