chamber I3 attached to the upper end of the pipe
In Figs. 1 to 6, inclusive, I have shown one form
of auxiliary valve means for this purpose in which
the chamber I3 is provided with a projection or
inwardly extending offset 25 and a port 26 de
I, which chamber serves as an auxiliary valve
chamber and has formed thereon or attached
thereto the discharge nozzle 3. 'I'he upper end

with the inlet end of the nozzle. For cooperation

a gland or followerflâ clamping suitable packing

to form between them flow passages 28; and each

upper, outwardly projecting- Y endk of said rodV
section I1 carries an operating handle or lever I9,
20 whereby the rod as a whole may beraised and
lowered to operate the valve 1. A coiled spring
20 disposed about the rod section I1 between the
passage of variable size between the chamber and
port to graduatively control the flow of water
therefrom to the nozzle, while when either passage
28 is'disposed in register with the port a full ñow
of waterto the nozzle is allowed. In the normal 20r
position of the parts one of the valve wings is
centrally disposed beneath the port 26 and spaced
coupling I8 and the top of the stuffing box or a
such a distance therefrom that when the handle
thimble 2| bearing thereonv serves to hold the

I1, through lwhich rod> section, cap and the side
30 walls ofthe slot of th'ef head 22 passes a pin or

pipe and drain outlet 4 for'the discharge of all
residual Water remaining in the stand pipe above
the valve 1. In practice the Water supply con
nections to the standpipe are arranged below
55 the frost line, and this drainage'action ensures
that no residual water from a supply action is

Hence
when a full flow of water from the nozzle 'is not
desired or required the amount of flow may be
reduced for any particular service purpose.y

In the construction shown. in Figs. 7, 8 and 9
the outlet chamber Iâa has fitted therein a stuffing
box I4a which isy flanged at its top for the en
gagement therewith of 'a flanged clamping‘ring '
29 threaded onto the casing and‘wherebyv the 45
stuffing box is held from outward displacement'.
This stuffing box conforms generally, so far as
its packing features are concerned, with the struc
ture shown in Figs. I to 6, inclusive,`and its similar
parts are correspondingly numbered. This box
I4a, however, is formed with a depending shell‘30
provided in its side with a port 3l facing the
nozzle and having an annular bottom wall 32
formed with sets of valve ports 33. The coupling
member Ißa in this construction has a circular
flange or valve disk 34 provided with arcuate slots
35 for cooperation with the sets of ports 33 to
secure a graduative discharge action. The shell
30 may be provided with a spline or key projection
36 to engage a seat groove 31 in the casing for
holding the shell from rotationïand ensuring ac
curate positioning of the valve ports 33. The

obvious reasons. yIn order to avoid this objection
In both forms of the auxiliary »valve means
I provide vmeans whereby after opening of> the disclosed the construction -and range of move

may be reduced and »graduatively controlled', toward the stationary valve member inthe auxil 70

2,109,187
to the nozzle as long as valve 'I is open and in the
fullest ñow obstructing position of the auxiliary
valve. Thus in the event that the handle should
not be returned to normal position after a
discharge action, that fact will .be vvisually indi
cated by the flow of a small amount of water from
the nozzle, ensuring attention being given to cut
oil the flow by returning valve 'I to closed posi
tion for a drain »action and to'prevent freezing
10 of the hydrant during freezing'weather.
My
invention thus provides in addition to its advan
tageous features described a >simple safeguard
against the valve 'l being left open through over
sight after use of the hydrant, whereby the
frostproof property of the hydrant‘rstructure is
maintained and preserved.
From the foregoing description,v taken in con
nection with'the drawings, the construction, mode
of operation and advantages-of my invention
20 will be readily understood, and it-will be seen
that the invention provides a frostproof hydrant
or other frostproof water service apparatus
whereby either a full or graduative discharge of
water from the discharge nozzle may be secured
25 at will and by the provision of a simple and
eii‘lcient type of means for the purpose. vAlso it
will be seen that the invention provides auxiliary
valve means for a graduative water discharge ac
3
nozzle and-operative by said operating means
in the open position of said inlet valve for gradu
atively regulating the discharge of water through
the nozzle.
2.'In a frostproof hydrant, the combination
of a-stand pipe having a water inlet and a drain
outlet at its lower end and a discharge nozzle at
its upper end, a water inlet valve in said pipe
movable upwardly to a position in which it opens
communication between the inlet and stand pipe 510
for a full flow of water to the nozzle and closes
communication between the drain outlet and
stand pipe and downwardly to a position in
which it closes the inlet and opens communica
tion between the drain outlet and stand pipe,
means movable in a certain general direction for
opening and closing the water inlet valve, and
a valve movable with the inlet valve on its up
wardv and downward movements into and out of
operative relationship to the discharge nozzle
for regulating the discharge of water from the
nozzle in the open position of the inlet valve,
said regulating valve being operable by move
ment of 'the aforesaid means in a diiîerent gen
eral direction from the first-named general di es
rection for graduatively regulating the discharge
of water through the nozzle.

of a stand pipe having a water inlet and a drain l
30 with the normal operation oi the hydrant and
outlet at its lower end and a discharge nozzle
at its upper end, a valve in said pipe movable
upwardly to a position in which it opens com
munication between the inlet and stand pipe for
a full ñow of water to the nozzle and closes com
munication between the drain outlet and stand
>pipe and downwardly to a position in which it
closes the inlet and opens communication be
tween the drain outlet and stand pipe, valve
governing means movable in a vertical direction
for opening and closing the valve, said means i
being also movable in a horizontal direction, and
regulating valve means including a member
movable with the inlet valve in its upward and
downward movements into and out of operative
relationship to the discharge nozzle and operable ~'
by movement of the valve governing means in a
without endangering its frostproof properties. It
will further be seen that the invention provides
auxiliary means for a graduative flow discharge
action which may be applied to and employed in
conjunction with the parts of an ordinary hy
drant valve mechanism and without material de
parture from approved types-of frostproof hy
drant or like water service structure. While the
construction is such that the customary return
of the operating handle to normal position after
a water supplying action ensures that the main
valve will be returned to water cut off and drain
position, the invention further safeguards the
apparatus against liability of freezing'by pro
viding a means for indicating‘whether or not
the main valve has been returned to cut off posi
tion, thus enabling measures to be taken to pre
vent freezing in case that through carelessness
or inattention on the part 'of kthe operator the
operating handle should be left in valve opening
position.
It will, of course, be understood that while I
have shown certain embodiments of >myvinven

the form, details of constructionï and arrange
