Disclosure of Invention
Oscillating windshield wipers have a number of prob¬ lems which cause such obstructed or impaired windshield vision. With an iced-over exterior windshield, the wipers are worthless in attempting to clear the windshield until the ice or snow on the exterior surface of the windshield has melted. However, even with such ice or snow melted, the oscillating wiper blades will serve to glaze over the windshield with ice in the event of the windchill factor, per se, is below freezing, or in the event the windchill factor, aggravated by the vehicle's forward speed, is be¬ low freezing. Even assuming the exterior surface of the windshield is clean and clear, the very action of the os¬ cillating windshield wiper arms, moving back and forth, impairs or interferes with the driver's clear vision.
Worn wiper blades are ineffective in cleaning water mois¬ ture and dirt from the windshield's exterior surface and, as such, can neither render clear, let alone to maintain clear, the exterior surface of the windshield. And, re- gardless of the condition of the wiper's blade arms, the oscillating blade arms eventually wear annular grooves into the exterior surface of the windshield. Such annular grooves are permanent, impair the driver's vision, and, during nighttime -■driving. *-the headlights from oncoming vehicles aggravate the impairment of the driver's vision. In addition to vision obstruction and impairment problems caused by ice, ice-encrusted snow and snow on the exteri¬ or surface of the windshield, dirt, collected water, wa¬ ter deposited from rainfall and moisture on the exterior surface of the windshield further obstruct or otherwise impair the driver's vision. As sometimes will happen, a driver will be driving his vehicle on the highway with his windshield clean and clear; but then, suddenly, a mile down the road, the driver runs" a sudden downfall or cloudburst with his vision totally obstructed by deluges of rain and water. Accordingly, the objects of the inven¬ tion are to contribute to the solution of the discussed problems of the art by providing a vehicle window clean¬ ing device which replaces the windshield wipers. High- speed blower means, with high-impact exhaust air veloci¬ ty, ducted to air nozzles, remove water, rain, moisture and dirt from the exterior surface of the vehicle's wind¬ shield, clean the windshield surface, render the wind¬ shield surface clear, and maintain the windshield surface clear, whether the vehicle is stationary or moving. High- temperature heater means, combined with such high-speed blower means, melt all the ice, ice-encrusted snow and/or snow upon the exterior surface of such windshield, and thereupon remove any water, moisture and dirt remaining upon the exterior surface of the windshield, clean the windshield surface, render such windshield surface clear, and serve to maintain such windshield's surface clear. In an embodiment of this invention, not only are the high-speed blower means and high-temperature heater means operatively disposed relative to the exterior surface of
the windshield, but also relative to the exterior sur¬ faces of the right-side front and rear windows, left-side front and rear windows, and rear window. In all invention embodiments, the high-speed blower means and the high- temperature heater means are electrically powered by the vehicle's electrical system and are switch-controlled. In the modified invention, only electrically powered high-speed blowers, with high-impact exhaust air veloci¬ ty, ducted to air nozzles, are employed to clear not only the exterior surface of the windshield but also the left and right side-view mirrors and the exterior surfaces of the left-side and right-side front and rear windows, and the rear window, of any rainwater, water, moisture, de¬ bris or loose powder snow. In this modified invention, the high-speed blowers are powered by the vehicle's elec¬ trical system and are switch-controlled. Worn windshield wiper blades are ineffective in clearing rainwater, water, moisture, debris or loose powder snow from the ex¬ terior surface of the windshield; and, windshield wipers since not so employed, have no clearing effect with re¬ spect to the left and right side-view mirrors and the ex¬ terior surfaces of the left-side and right-side front and rear windows, and the rear window.

Best Mode for Carrying Out the Invention
In Fig. 1 of the drawings, reference numeral 1 gener¬ ally refers to the first embodiment of the invention. Shown in phantom lines are the vehicle 3, windshield 5 and the firewall 7 of the engine compartment. The housing 9 for the combined electrically powered high-speed blower 11 and the high-temperature electrical heater 13 is ap¬ propriately mounted in fixed relationship on the firewall 7. The blower 11 and heater 13 are both electrically pow¬ ered and have leads 15 operatively connected to the ve- hide's electrical system. Switches 17 and 19 control the blower 11 and heater 13, respectively. The switches 17 and 19 are appropriately located on the vehicle's dash for the driver's access and convenience. While the blower 11 is operated independently of the heater 13 by closing the blower switch 17, the blower switch 17 must be closed in order to operate the heater 13 by closing switch 19 to complete the circuit to the heater 13. The high-speed blower 11 must produce a wind velocity within the range of 120-200 MPH. The high-temperature heater 13 must pro- duce a temperature within the range of 120-150 degrees F. An air intake duct 21 communicates directly with the com¬ bined blower-heater housing 9; and an exhaust duct 23 communicates directly with the combined blower-heater housing 9. Upon closing the blower switch 17, ambient air from the engine compartment is drawn into the housing 9
and forced therefrom by the blower 11 at high velocit through the exhaust duct 23. When the heater switch 19 i closed as well, ambient air is drawn through the intak duct 21 into the combined blower-heater housing 9 will b heated by the high-temperature electrical heater 13 to high temperature and forced from the housing 9 throug the exhaust duct 23. The exhaust duct 23 communicates di rectly with an exhaust manifold 25 which has six manifol branches 27, 29, 31, 33, 35 and 37 in direct communica tion with the manifold 25. Each of the terminal ends 3 of the manifold branches 27, 29, 31, 33, 35 and 37 is i the configuration of and thereby defines a sphere havin removed therefrom a segment with one base, the bas being, as shown in Fig. 5, where the air passage exits Each of the terminal ends 39 freely and complementall mounts a directional air jet 41, defining a swivel-join relationship. A locking screw 43, whose threaded shan portion 45 is appropriately engaged with a transvers tapped hole 47 in air jet 41, locks the air jet 41 in it discrete directional position where same is disposed rel ative to its terminal end 39 by sufficient tightening o the locking screw 43. The air jets 41, together wit their terminal ends 39, define air nozzles 49. The ai nozzles 49 are disposed below the bottom 51 of the wind shield 5 with their directional air jets 41 appropriatel positioned and adjustably disposed so that the ambien air, forced by the high-speed blower 11 through the ex haust duct 23, exhaust manifold 25, manifold branches 27 29, 31, 33, 35 and 37, and their respective air nozzle 49, will be directed upon and will impact the entire ex terior surface of the windshield 5 with such tremendou force that all dirt on the exterior surface of the wind shield 5, all collected water on the exterior surface o the windshield 5, all water deposited on the exterio surface surface of the windshield 5 from rainfall and al moisture on the exterior surface of the windshield 5 wil be instantly removed by being blown away from th exterior surface of the windshield 5, with the desire result that the windshield exterior will be cleaned rendered clear and maintained clear removing any prio
obstruction to or impairment of the driver's vision. When the exterior surface of the windshield 5 is covered with ice, ice-encrusted snow and/or snow, both the blower switch 17 and heater switch 19 are closed causing ambient air to be drawn through the intake duct 21 by the blower 11, to be heated by the high-temperature heater 13 in the combined blower-heater housing 9 and to be forced through the exhaust duct 23, exhaust manifold 25, branches 27, 29, 31, 33, 35 and 37, and their respective air nozzles 49. Such heated air will impact the entire exterior sur¬ face of the windshield 5, melt and blow away all ice, ice-encrusted snow and/or snow from the entire exterior surface of the windshield 5, followed by all dirt and re¬ maining moisture being instantly removed by being blown away as well as from the entire exterior surface of the windshield 5, with the desired result that the windshield exterior surface will be cleaned, rendered and maintained clear.
The second embodiment of the invention, generally re- ferred to by reference numeral 53 in Fig. 2, utilizes the same structure of the combined blower-heater housing 9, high-speed blower 11, high-temperature heater 13, intake duc '21 and exhaust duct 23, shown and described with re- pect to Fig. 1. In the second invention embodiment 53, the exhaust duct 23 communicates directly with an exhaust manifold 55 that communicates directly with upstanding slits or slot-formed air nozzles 57, disposed below the bottom 51 of the windshield 5 and positioned so that the ambient air forced by the high-speed blower 11 will be directed upon and will impact the entire exterior surface of the windshield 5. The function of the second invention embodiment 53 is similar to the function of the first in¬ vention embodiment in melting and blowing away all ice, ice-encrusted snow and/or snow from the entire exterior surface of the windshield 5, followed instantly by all dirt and remaining moisture being instantly removed by being blown away as well as from the entire exterior sur¬ face of the windshield 5, with the desired result that the windshield exterior surface will be cleaned, rendered clear and maintained clear.
With respect to the first invention embodiment 1 the functional results obtained when only the blower switch 17 is closed may be referred to as the first mode; and the functional results obtained when both the blower and heater switches 17 and 19 are closed may be referred to as the second mode. Thus, it should be discerned and appreciated that when both the first invention embodiment 1 and second invention embodiment 53 are in their first mode, the functional results obtained are similar; and that when both the first invention embodiment and the second invention embodiment are in their second mode, the functional results obtained are similar.
The third embodiment of the invention, generally re¬ ferred to by reference numeral 59 in Fig. 3, utilizes the same structure of the combined blower-heater housing 9, high-speed blower 11, high-temperature heater 13, intake duct 21 and exhaust duct 23, shown and described with respect to Fig. 1. In the third invention embodiment 59, the exhaust duct 23 communicates directly with an exhaust manifold 61 that communicates directly with two upstand¬ ing elongated slits or slot-formed air nozzles 63, disposed below the bottom 51 of the windshield 5 and po¬ sitioned so that the ambient air forced by the high-speed blower 11 will be directed upon and impact the entire ex- terior surface of the windshield 5. When the blower switch 17 in the third invention embodiment 59 is closed, the third invention embodiment 59 is in its first mode with the functional results obtained that are similar to the functional results obtained when the first invention embodiment 1 is in its first mode. When both the blower and heater switches 17 and 19 in the third invention embodiment are closed, the third invention embodiment is in its second mode with the functional results obtained that are similar to the functional results that are ob- tained when the first invention embodiment 1 is in its second mode.
The fourth embodiment of the invention, generally re¬ ferred to by reference numeral 65 in Fig. 4, utilizes the same structure of the combined blower-heater housing 9, high-speed blower 11, high-temperature heater 13, intake
-8- duct 21 and exhaust duct 23, as shown in and as described with respect to Fig. 1. In the fourth invention embodi¬ ment 65, however, two combined blower-heater housings 9 are utilized, . each having a high-speed blower 11, a high- temperature heater 13, an intake duct 21 and an exhaust duct 23 for each side of the windshield 5. In the fourth invention embodiment 65, each of the exhaust ducts 23 terminates in an upstanding elongated slit or slot-formed air nozzle 67. As shown, the two air nozzles 67 are dis- posed below the bottom 51 of the windshield 5 and are po¬ sitioned so that the ambient air forced by their respec¬ tive high-speed blowers 11 will be directed upon and im¬ pact the entire exterior surface of the windshield 5. When the two blower switches 17 in the fourth invention embodiment 65 are closed, the fourth invention embodiment 65 is in its first mode with the functional results ob¬ tained that are similar to the functional results that are obtained when the first invention embodiment 1 is in its first mode. When both of the two blower switches 17 and the two heater switches 19 in the fourth invention embodiment 65 are closed, the fourth invention embodiment 65 is in its second mode with the functional results ob¬ tained that are similar to the functional results that are obtained when the first invention embodiment 1 is in its second mode.
The fifth embodiment of the invention, generally re¬ ferred to by reference numeral 69 in Fig. 7, shows the vehicle 3 with its windshield 5, right-side window 71 with its right-side mirror 73, right-side rear window 75, left-side front window 77 with its left-side mirror 79, left-side rear window 81, and rear window 83. Two up¬ standing nozzles 67, both of which are disposed below the bottom of the windshield 5, are positioned, as shown, so that ambient air forced by their respective high-speed blowers 11 will be directed upon and will impact the en¬ tire exterior surface of the windshield 5. One upstand¬ ing nozzle 67 is disposed below the bottom of the right- side front window 71 and is positioned, as shown, so that ambient air, forced by its high-speed blower 11, will be directed upon and will impact the entire exterior surface
of the right-side front window 71, along with such ambi ent air being directed upon and impacting the right-sid mirror 73. One upstanding nozzle 67 is disposed below th bottom of the right-side rear window 75 and is positione so that ambient air,, forced by its high-speed blower 11 will be directed upon and will impact the entire exterio surface of the right-side rear window 75. One upstandin nozzle 67 is disposed below the bottom of the left-sid front window 77 and is positioned, as shown, so that am bient air, forced by its high-speed blower 11, will b directed upon and will impact the entire exterior surfac of the left-side front window 77, along with such force ambient air being directed upon and impacting the left side mirror 79. One upstanding nozzle 67 is dispose below the bottom of the left-side rear window 81 and i positioned, as shown, so that ambient air, forced by it high-speed blower 11, will be directed upon and will im pact the entire exterior surface of the left-side rea window 81. Two upstanding 67 are disposed below the bot torn of the rear window 83 and are positioned, as shown so that ambient air, forced by their high-speed blower 11, will be directed upon and will impact the entire ex terior surface of the rear window 83. Each of the forego ing nozzles 67 utilizes the same structure of the com bined blower-heater housing 9, high-speed blower 11 high-temperature heat 13, intake duct 21 and exhaust duc 23, shown in and described with respect to Fig. 4 wit reference to the fourth invention embodiment 65. The tw combined blower-heater housings 9 for the windshield 5 i this fifth invention embodiment 69 are similarly mounte on the firewall of the engine compartment; only one o the combined blower-heater housings 9, however, is util ized for the right-side front window 71 and is appropri ately mounted on . the support structure within the conven tional door envelope for the right-side front window 71 only one of the combined blower-heater housings 9, howev er, is utilized for the right-side rear window 75 and i appropriately mounted on the support structure within th conventional door envelope for the right-side rear win dow 75; only one of the combined blower-heater housing
9, however, is utilized for the left-side front window 77 and is appropriately mounted on the support structure within the conventional door envelope for the left-side front window 77; only one of the combined blower-heater housings 9, however, is utilized for the left-side rear window 81 and is appropriately mounted on the support structure within the conventional door envelope for the left-side rear window 81; and the two combined blower- heater housings 9 for the rear window 83 are appropriate- ly mounted on the support structure within the vehicle's rear compartment. The blower and heater switches 17 and 19 are appropriately located on the vehicle's dash for the driver's access and convenience. Upon closing of the blower switches 17, ambient air, forced by the high-speed blowers 11 through the nozzles 67, will impact the ex¬ terior surfaces of the windshield, side windows, rear window and side mirrors with such tremendous force that all dirt, collected or deposited water or moisture there¬ on will be instantly removed by being blown away, with the desired results that the windshield, side windows, rear window and side mirrors will be cleaned, rendered clear and maintained clear. And upon all the blower and heater switches 17 and 19 being closed, all ice, encrust¬ ed snow and/or snow will be melted and thereafter removed by being blown away from the windshield, side windows, rear window and side mirrors, followed instantly by all dirt and remaining moisture being removed by being blown away, as well as the windshield, side windows, rear win¬ dow and side mirrors being cleaned, rendered clear and maintained clear.
In Fig. 8, reference numeral 85 generally refers to the modified invention. Shown in phantom lines are the vehicle 87, windshield 89 and firewall 91 of the engine compartment. An electrically powered high-speed blower 93 is appropriately mounted on the firewall 91. Air intake duct 95 and exhaust duct 97 communicate with the blower 93, with the exhaust duct 97 being tee-connected to the exhaust manifold 99. The exhaust manifold 99 has left and right manifold branches 101 and 103 which communicate with respective left-side and right-side air nozzles 105
and 107 which are disposed and located below the bottom 109 of the windshield 89 so that ambient air, drawn from the engine compartment through air intake duct 95 and forced by the operation of the blower 93 through the ex- haust duct 97, will be directed upon and will impact, via air nozzles 105 and 107, the entire exterior surface of the windshield 89 with such tremendous force that any rainwater, water, moisture, debris or loose powder snow will be cleared from the exterior surface of the wind- shield 89. Shown are a left side-view mirror 111 and a right side-view mirror 113. A left trident branch 115, disposed through the frame of the left-side front door 117, carries on its terminal end an 0-ring seal 119 which, when the door 117 is closed, mates with an 0-ring seal 121, carried on the proximal terminal end of the ex¬ haust manifold 99, disposed through the chassis frame for the left-side front door 117, and thereby establishes sealed communication between such proximal exhaust mani¬ fold and the left trident branch 115. The other end of the left trident branch 115 has top, """middle and bottom air nozzles 123, 125 and 127. Ambient air, forced through the left trident branch 115, will be directed upon and will impact, via top and bottom air nozzles 123 and 127, the entire exterior surface of the left-side front door window 129 to similarly clear same of any rainwater, wa¬ ter, moisture, debris or loose powder snow; and with the middle air nozzle 125 directing and impacting forced am¬ bient air upon the mirrored surface 131 of the left side- view mirror 111 to similarly clear same. A right trident branch 133, disposed through the frame of the right-side front door 135, carries on its terminal end an 0-ring seal 137 which, when the door 135 is closed, mates with an 0-ring seal 139, carried on the proximal terminal end of the exhaust manifold 99, disposed through the chassis frame for the right-side front door 135, and thereby es¬ tablishes sealed communication between such proximal ex¬ haust manifold and the right trident branch 133. The oth¬ er end of the right trident branch 133 has top, middle and bottom air nozzles 141, 143 and 145. Ambient air, forced through the right trident branch 133, will be di-
rected upon and will impact, via top and bottom air noz¬ zles 141 and 145, the entire exterior surface of the rignt-side front door window 147 to similarly clear same of any rainwater, water, moisture, debris or loose powder snow; and with the middle air nozzle 143 directing and impacting forced ambient air upon the mirrored surface 149 of the right side-view mirror 113 to similarly clear same. In Fig. 11, the device 85 has the same structure as shown in Figs. 8-10, with the exception that, instead of employing the air intake duct 95 to draw ambient air from the engine compartment, an air intake duct 151 is option¬ ally employed to draw ambient air from the passenger com¬ partment. Further shown in Fig. 11 are the left-side rear window 153 and the rear window 155. An electrically pow- ered high-speed blower 157 is appropriately mounted in the rear compartment 159 of the vehicle 87. An air intake duct 161 communicates with the blower 157; and an exhaust duct 163 communicates directly with the blower 157 and is connected in communicative relationship, as shown more discernably in Fig. 13, both to an air nozzle 165 and to an exhaust manifold 167. Upon operation of the blower 157, ambient air, drawn from the rear compartment 159 through the air intake duct 161 and forced by the blower 157 through the exhaust duct 163, will cause such forced ambient air to be directed upon and impact, via air noz¬ zle 165, the entire exterior surface of the rear window 155 with such tremendous force that any rainwater, water, moisture, debris or loose powder snow will be cleared from the entire exterior surface of the rear window 155. The air nozzle 165 is disposed and located below the bot¬ tom 169 of the exterior surface of the rear window 155. Ambient air, forced through the air nozzle 165, is di¬ rected through a vehicle body opening 171 which, when the blower 157 is not in operation, is closed and sealed by a spring-biased flapper valve 173. When the blower 157 is in operation, the force of the ambient air being directed through the air nozzle 165 and vehicle body opening 171 opens the flapper valve 173; and, upon cessation of the operation of the blower 157, the restoring force of the spring component of the flapper valve 173 causes the
valve 173 to close and seal the vehicle body opening 171. It should be noted that the structure, shown in Figs. 11-13 and already described, and to be described with reference to Figs. 11-13, for the clearing of rainwater, water, moisture, debris and loose powder snow from the left-side and right-side rear windows, and the rear win¬ dow, are the same with the exception of the optional structure of the air intake duct 175, shown in Fig. 13. Instead of employing the air intake duct 161 to draw ambient air from the rear compartment 159, the air intake duct 175, communicating with blower 157, may be substi¬ tuted to draw ambient air from the passenger compartment of the vehicle 87.
Hence, ambient air can be drawn by the blower 93 from the engine compartment via air intake duct 95 and ambient air can be drawn by the blower 157 from the rear compart¬ ment via the air intake duct 161; in another embodiment, ambient air can be drawn by the blower 93 from the pas¬ senger compartment via the air intake duct 151 and ambi- ent air can be drawn by the blower 157 from the passenger compartment via the air intake duct 175; in another em¬ bodiment, ambient air can be drawn by the blower 93 from the engine compartment via air intake duct 95 and ambient air can be drawn by the blower 157 from the passenger compartment via air intake duct 175; and in a final em¬ bodiment, ambient air can be drawn by the blower 93 from the passenger compartment via air intake duct 151 and ambient air can be drawn by the blower 157 from the rear compartment via the air intake duct 161. The exhaust manifold 167 angles around within the interior of the left side of the vehicle's body, as is shown, to the chassis frame 177 for the left-side rear door 179 and terminates with a ring-like seal 181 where it communicates in sealing relationship with a similarly configured ring-like seal 183 at one end of an exhaust branch 185, flattened to run interiorly and without interference within the left-side rear door envelope and then outward through the exterior body of the left-side rear door 179 and thence upwardly to terminate in top, middle and bottom air nozzles 187, 189 and 191. Communi-
cation of the exhaust manifold 167 with the exhaust branch 185 is only established when the left-side rear door 179 is closed.
The same structure, of the seals 181 and 183, flatten- ed exhaust branch 185, and the top, middle and bottom air nozzles 187, 189 and 191 are employed for the right-side rear door. Hence, ambient air, forced through the exhaust manifold 167, will cause the nozzles 187, 189 and 191 to similarly clear the exterior surfaces of both the left- side and right-side rear windows of rainwater, water, moisture, debris and light powder snow.
