(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. I - 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. Fig. 3 is a vertical sectional view taken on the line 3—-3 of Fig. 2. 10 ‘Fig; 4 is a view similar to Fig. 3 but showing some of ‘the parts-in elevation; and furthermore showing the pipes located ‘outside of the wind shield frame.

These different types are ar- _ , ice and snow. 25 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. ‘ Another one- of the objects of this invention is ranged .side bySide, each takingup one-half the width of the windshield. f \ ‘Fig. 7 is a fragmentary elevational view of a windshield seen fromthe interior of a car and constructed according to this invention. ‘ Fig. 8 is a sectional view of Fig. 7.

This light is cennected to the battery ef the ve 25 hicle and may be connected into an electric; cir cuit by a suitable switch at the driver's seat, so that it may be used as a turn indicator or to at tract the attention of other drivers or pedestrians, on a pivotally mounted arm 24 connected with a 20 rotative bushing or valve 28 controlled in a man ner similar to the valve l8- previously described. The windshield‘ 2| is provided with a frame 25 through the pipes 26 for conveying the heated vfluid which operates the motor 23. 25 Fig. 6 shows another portion of the windshield, indicated by reference numeral 2 I‘, provided with a duplicate cleaning device consisting of the squeegee or similar element 22, the motor 23, the arm “and the pipes 26'. These pipes are ar ranged external of the frame 25' of the wind either at the front windshield or at the rear win 30 dow of the vehicle. - The pipe I6’ is, connected with a supply pipe l8" 30 _ shield. which is intended to be connected to receive some of the exhaust gases from the automobile or to receive other heated and moving ?uid or sub 35 stances. From this pipe the substances pass through the pipe line I6 and then through the motor l5 to revolve the squeegee element l2.
