5 Claims. (C1. 137-68)
My invention relates to improvements in valves chamber in either direction of its movement
therein. The, lower end of the valve member 2I
for humidifying apparatus for radiators, partic
ularly'steam and hot water radiators.
The primary object of my invention is to pro
5' vide an eñicient valve for humidifying apparatus
for, use in maintaining the proper degree of
humidity and purifying the air in rooms heated
by steam or hot water radiators and which is
adapted for attachment together with said ap
l ~` paratus to standard types of such radiators and
substantially concealed from View thereby.
Other objects are to provide a valve appara
tus of the character and for the purpose above
set forth for use in connection with evaporation
~';- tanks adapted to be set into the radiators in
concealed positions and a fresh water supply for
said tanks, and which is equipped with means
controlled by the amount of water in said tanks
to maintain said water at a fixed level and also
extends into the intermediate casing portion I9
and is bifurcated, as at` 24, for a purpose pres
ently seen. A telescopic plunger rod 25 is slid
ably mounted in the top of the float chamber
casing Il, centrally of the latter, in a sleeve 25
inserted through said top and into said charn
ber. The plunger rod 25 comprises upper and
lower telescopic sections 2'I and 28 having a slot
and pin connection 29 and 3G, respectively, there
between, for a purpose

end of the upper Isection
portion 32 and a lateral
flange 33 below said portion. A coil spring 34
is interposed between the top of said casing Il
and a washer 35 resting on a pin 38 passing
through the lower end of the section 28. A
,controlled by an oversupply of water passing bifurcated bracket 3l. is secured by rivets 38 in
the intermediate casing portion I9 to the top
thereinto to shut ofi said water supply.
Other objects are to provide a valve for the wall thereof. A rocker arm 39 is pivotally

My control valve 5 comprises an upstanding between the arms of the latch 43 at the other

The beforementioned slot and pin connection
29 and 3i) between the sectionsl 2l and 28 of the
plunger rod 25 is in the nature of a safety pro
vision, preventing said rod from being thrust
20
downwardly beyond its valve-seating position.
For this purpose the slot 29 and pin 3Q are ar
ranged so that in the valve-seating position of
the rod Z5 further downward pressure there
against is ineffective against the section 28.
The parts are re-conditioned for operation by
pulling the plunger rod 25 outwardly, by way of
the hand-grip 32, swinging the trip latch to its
described position beneath the plunger 33 and
suspending the pan 45, emptied of its contents,
on said trip latch.
The foregoing constitutes a detailed descrip
tion of a preferred embodiment of' my invention
and it is believed that its operation and construc
tion will be clear therefrom.
Obviously, however, the details described may
be varied without departing from the inventive
concept disclosed, and it is to be understood that
right is herein reserved to all such modiñcations
falling fairly within the scope of the protection
prayed.
What I claim is:

the water to said levelto operate said member in
one direction, a tensioned plunger for operating
50 said member in the opposite direction and mov
able to an ineiïective position, and means for
holding said plunger in said position and includ

by said housing engageable with said float to lower
said float in the liquid against the buoyancy of
said float, said housing having an overflow port,
a receptacle below said overiiow port, and a rock
70 able supporting member for said receptacle hav
ing an end thereof engageable with said spring
pressed means to normally hold said spring
buoyancy of said float, said housing having an
opening through which said plunger engages, a
receptacle disposed below said overflow port, and
a rockable supporting member for said receptacle
having an end thereof engageable with said 20
plunger to normally hold said plunger against
operation, the weight of liquid in said receptacle
swinging said supporting member to a position
disengaged from said plunger.
4. A liquid lever controlling valve comprising 25
a housing having a lo-wer outlet port and an
overflow port above said outlet port, an inlet
chamber carried by said housing provided with
spaced apart axially alined valve seats, a valve

housing, a rock lever carried by said housing hav
ing the ends thereof connected to said valve mem
ber and said float respectively, spring-pressed

said float to lower said iioat in the liquid against 35
the buoyancy of said float, a receptacle communi
eating with said overflow port, and a combined
trigger and receptacle supporting member rock
ably carried by said housing, said supporting
member having an end thereof engageable with 4.0.
said spring-pressed means to normally hold said
spring-pressed means against operation, the
weight of liquid in said receptacle swinging said
supporting member to a position disengaged from
said spring-pressed means.
5. A liquid lever controlling valve comprising
a housing having a lower outlet port and an
overflow port above said outlet port, an inlet
chamber carried by said housing provided with
spaced apart axially alined valve seats, a valve
member in said chamber, a iioat in said housing,

lloat to lower said float in the liquid against the
buoyancy of said float, a flanged sleeve slidably
carried by said housing engaging about a portion~
of said plunger, said sleeve having opposed elon
gated slots, a. pin carried by said plunger loosely
engaging in said slots, a receptacle disposed be
low said overflow port, and a rock member car
ried by said housing having one end thereof
detachably secured to said receptacle and thev
other end thereof engageable with the flange of 651
said sleeve to thereby hold said plunger in in
operative position, the weight of liquid in. said
receptacle swinging said rock member out of en
gagement with said flange to thereby release said
plunger for engagement with said float.
