1 Claim. (01. 15-250)
This invention relates to new and useful im~
Drovements in a windshield heater.
_
The invention has for an object the construc
tion of a heater capable of heating a windshield
s for the purpose of keeping it clear of ice, snow
and
vapors.
’
_
The invention particularly proposes the con,
struction of a windshield heater which is char
acterized by the provision of a squeegee element
l 0 of the like operating. against the outer surface
of a windshield and. used in combination with‘a
heated substance, preferably the exhaust from
the vehicle, having said windshield, to keep the
windshield clear.

with a’ windshield provided with a windshield
heater constructed according to this invention.
~ Fig. *2 is a schematic outside elevational view
of the windshield with ‘the heater applied; this
view is called schematic because certain of the
parts have been projected out of their actual
plane so that the complete circuit of the pipe
system may be easily traced.

line 3—-3 of Fig. 2.

Another object of this invention‘ is to provide
pipes for the passage of ‘the heated ?uid. which
pipes preferably extend around the windshield,
either embedded into the frame which holds the
windshield, or outside of the frame, or around
the edges of the windshield itself.
- Still further the invention contemplates the
associationof a heater with the circulating heat
30 ed substance so that this heated substance may
also operate the heater in addition to performing
its other duties.
