1 Claim.
This invention relates to a-device for supply
ing moisture to internal combustion motors, the
general object of the invention being to provide
means for connecting the inlet manifold to the
5 radiator so that moist air will be drawn into the
manifold, with means for preventing too much of
the moisture to be carried into the manifold.
This invention also consists in certain other
features of construction and in the combination
10 and arrangement of the several parts to be here
inafter fully described, illustrated in the accom
panying drawing and speci?cally pointed out in
the appended claim.
In describing the invention in detail, refer

An opening I9 is, located in the top of the re
ceptacle I and is enclosed by a cage 20 which con
tains a ball valve 2i which closes the opening I9
under the action of gravity but which will open
said opening if the receptacle I is turned over,
this arrangement being used when the device is
placed on an aeroplane. When the vehicle is in
upright position the valve 2| will close the open
ing I9 and thus prevent the entrance of air into
the receptacle.
The lower part of the receptacle I contains wa
ter which, of course, can never pass above the
level shown by the dotted line 22.
When the motor is in operation moist air will
