WINDSHIELD CLEANING DEVICE
Ernest J. Eaddy, Spartanbnrg, S. 0.
Application April 5, 1937, Serial No. 135.149
6 Claims.
This invention relatesv to a windshield cleaning
device and has for its object to provide, in a
manner as‘hereinafter set forth, a normally in
‘ active device of the vclass referred to for installa
5 tion in an automotive vehicle forwardly and rear
wardly with respect to the windshield of the lat,
ter, made active, when occasion requires, from
the interior of the vehicle and when active pro
jecting a cleaning‘ liquid rearwardly in a direction
10 to impact against, the front of the windshield
whereby the said front is cleaned.
A further object of the invention is to provide,
in a manner as hereinafter set forth, a normally
inactive windshied cleaning device for installation
in an automotive vehicle forwardly and rear
wardly with respect to the windshield of the lat
ter, made active, when occasion requires, from
the interior of the vehicle and when active pro
jecting a liquid possessing a defrosting character
istic, rearwardly in a direction to impact against
the front of the windshield whereby the latter
is defrosted.
‘Further objects of the invention are to pro
vide, in amanner as hereinafter set forth, a de
vice of the class referred to which is simple in
its construction and arrangement, strong. dur
able, compact, readily installed with respect to
the windshield of an automotive vehicle, thor
oughly eiiicient in its use, conveniently operated,
quickly assembled and comparatively inexpensive
to manufacture.
To the above ends essentially and to others
which may hereinafter appear, the invention
consists of the novel construction, combination
35 and arrangement of parts as will be more speci?
cally described and as illustrated in the accom
panying drawings, wherein is shown embodiments
of the invention, but it is to be understood that
changes, variations and modi?cation may be re
40 sorted to which fall within the scope of the
invention as claimed.
In the drawings:

therewith of the liquid discharge nozzles of a
cleaning device in accordance with this invention,
Figure 2 is a fragmentary view in perspective
of the closed type body of an automotive vehicle

arrangement therein of the rear portion of a
cleaning device in accordance with this inven
tion,

a modi?ed form of cleaning device in accordance
with this invention, and
Figure 7 is a section on line 1-1, Figure 6.
With reference to Figures 1 and 2 the vehicle is
generally indicated at 8 and includes a body 9 of
the closed type. Figure 2 illustrates an instru 15
ment board Ill arranged within the body 9. The
cowl of the vehicle is indicated at H on Figures 4
and 5 and at l2 on Figure 6. The windshield is
indicated at I 2'1 Figures 1, 2 and 6.
Figures 1 to 5 illustrate one form of the device 20
and Figures 6 and 7 another or modi?ed form.
Each form of the device includes a container I3
for a body of cleaning liquid or fluid. Preferably,
the liquid will possess a defrosting characteris
tic. Extending from the container I3 is a liquid
feed line it which at its outer end is connected
to and opens into the lower end of an annular
peripherally ?anged housing or coupling I5 con
stituting a check valve chamber l6 having con
?ned therein a spring controlled ball valve I'I
constituting a check. The seat for valve I1 is
indicated at II. The upper end of housing l5
extends into, is secured to and has controllable
communication with the lower leg IQ of a ver
tically arranged T coupling 20 disposed on the
bottom edge of the leg I! and arranged forwardly
of the instrument board Ill. The upper and
intermediate legs of the coupling 20 are indi
cated at 2|, 22 respectively. The leg 2| is ar
ranged over and spaced from leg It. The leg 22
merges into the rear sides of the legs l9, 2| at
the inner ends of the latter and extends rear
wardly from legs l9, 2i. Arranged over and
spaced from housing I5 is an annular peripher
ally fianged housing or coupling 23 constituting
a check valve chamber 24 having con?ned there
in a spring controlled ball valve 25 constituting a
check. The seat for valve 25 is indicated at 25.
The inner end of housing 23 extends into, is
secured to and has controllable communication 50
with the leg 2|. Secured to the upper end of
housing 23 is a liquid supply line or» pipe 21.
The seats I8, 26 are arranged within the hous
ings I5, 23 respectively intermediate the ends of
the latter. Extending into the rear end of leg 55

The housings I5, 23 and the elements carried
thereby provide alternately opening controlling
valve structures. The cleansing liquid or ?uid is
termed a cleansing medium. The T-coupling 20
provides a cleansing medium receiving chamber
89 with which the lines i4, 21 and the pump 33
communicate. The line I 4 is normally in com
munication with chamber 89. The line 21 is nor
10 mally closed to chamber 89. The pump 33 is in
permanent communication with chamber 89.
The ports 6|, 8‘! are directed towards the front
of windshield and function, when a form is made
active, to direct the cleansing liquid to impact in
16 spray-like form the front of the windshield for.
cleaning it, or when a liquid possessing a defrost
ing characteristic employed is directed to impact
against the front of the windshield by the ports
6|, or 81, the windshield will be defrosted.
