within the shell into the radiator, it has been found that
a length of wick, preferably, but not necessarily, approxir
mately cylindrical in form, serves effectively. One form
of the wick is illustrated in FIG. 1 at 14, wherein the
wick is held in an elbow-shaped partially tubular member
15 open at both ends and containing the wick 16; the ends
of the member 15 are indicated at 17 and 18. The hori
zontal portion 19 of the member 15 has an elongated cut
out portion 19a along the top thereof, exposing the wick

of illustration and that it is therefore neither desired nor
intended to limit the invention necessarily to ‘any or all
of the exact details shown or described except insofar as
they may be deemed essential to the invention as de?ned
in the appended claims.
Referring brie?y to the drawing, FIG. 1 is a radiator
valve connected to the end wall of a radiator, with parts
broken away and partly in section.
FIG. 2 is a fragmentary enlargement of FIG. 1, but
illustrating a modi?ed form of the wick shown in FIG. 1.

It is to be noted that the wick 16b is shorter than the
other wick members set forth and terminates in the pas
sage 28 through the radiator wall 13. This serves to il
lustrate the principle that water drawn along the wick
from the shell 10 will pass off the rear end of the wick on
to the ?oor of this passage and thus ?ow down into the
The principle of operation of all of the wicks illustrated
and described above, is the same; that is, they will draw
condensate out of the shell and pass it into the radiator,
thus preventing clogging of the nipple and thus shutting

The shell 10 has the usual cap 40 secured thereto con

reference to the constructions shown in the drawing, it is
to be understood that such is not to be construed as im
parting limitations upon the invention, which is best de
?ned in the following claims.
In the case of any and all of the wicks discussed above,
it is to be understood that wherever they are mounted
41 can evaporate through the holes 42. To prevent the
forrration of a ?lm of condensate in the holes 42, a cylin

drical wick 43 is mounted against the inner wall of the
cap 40, and preferably has sut?cient height to extend to
or above the lower edges of the holes 42.
Secured against the lower or inner surface of the roof
31, is an annular wick 44 preferably having 21 depending
?ange 45, the axial opening 46 of the wick being aligned
with the passage 34. Thus the wick 44- draws condensate
away from the passage ‘34 and radially outward therefrom,
to pass down the inner wall of the shell 10.
It will be noted that in each of the arrangements pre
viously described a portion of the wick is on contact with
or extends beyond the edge of the ori?ce or passage which
is to ‘be drained of condensate. It is essential that the
wick be so positioned in order to assure contact between
the wick and any condensate which may enter or be
formed in the ori?ce as without such contact ‘the wick can
not function.
Wherever the term “wick” is used herein it is to be
understood that the element referred to serves the com
mon purpose and function of wicks and that it is con
structed as wicks are generally constructed, i.e., of a plu
rality of relatievly loosely twisted, braided, knitted, felted
or woven ?bers, or a substitute, to operate by capillary at
traction to convey liquid away from a source to a distance
or place remote from the source.
It is obvious from the present disclosure that a radiator

radiator, when provided with wicks arranged and posi
tioned substantially as set forth with respect to the ori~ 4 O
tical reasons that they should remain positioned against
such surfaces, they may be secured to such surfaces by
any desired means or in any manner.
For example, the
wicks may ‘be cemented to the surfaces, not shown.
I claim:
1. A radiator valve comprising a shell enclosing a com
partment containing a thermodynamic valve unit, a nipple
for connecting the interior of the shell to a radiator, an
escape ori?ce through which air may pass out of the shell,
‘and a valve seat housing mounted in an opening in a Wall
of said compartment, said housing having an axial passage
therethrough with a valve seat located therein, the combi
nation of said valve seat and said thermodynamic valve
unit being adapted to control the movement of air and
steam through the valve, and wick means for drawing con
densate out of and away from said passage.
2. A radiator valve according to claim 1, a portion of
said wick means being positioned in contact with a por
tion of the edge of an ori?ce of said passage.
3. A radiator valve according to claim 1, a portion of
said wick means extending into an ori?ce of said passage.
4. A radiator valve according to claim 1, a portion of
said wick means being positioned anterior to and extend
ing toward ‘but not entering into an ori?ce of said passage.
