Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
203 words
In combination, a vehicle, apparatus for imparting a pleasant fragrance to the air within said vehicle having a dashboard comprising housing means fully enclosed with a vent opening mounted within said dashboard with vent opening penetrating said dashboard, fan means within said housing means for blowing air through said vent opening into the interior of said vehicle, slide tray means open at the top for containing a material which upon evaporation has a pleasant fragrance, means within said housing means for accommodating said slide tray means beneath said vent, whereby air movement generated by said fan means passes over said tray causing evaporation of said material, said housing means converging downstream of said fan means to increase velocity of the air flowing over said material thereby enhancing the rate or material evaporation, and means conveniently located within said vehicle for selectively energizing or deenergizing said fan means whereby an occupant of said vehicle is able to conveniently and at will generate air flow, means for selectively permitting generation of said fragrance while said fan means is operating, and door means beneath said vent opening mounted within said dashboard accessible from the front for permitting convenient removal and replacement of said slide tray means.

Claim 3
Dependent Claim
35 words
The apparatus of claim 1 wherein said slide tray means is provided with a leader at the front end thereof facing said door means for permitting convenient grasping and removal of said slide tray means.
Claim 4
Dependent Claim
39 words
The apparatus of claim 2 having switch means mounted on said dashboard for controlling the operation and speed of said fan means thereby permitting the rate of discharge of the fragrance laden air into the interior of said vehicle.
Claim 5
Dependent Claim
63 words
The apparatus of claim 3 wherein said means for selectively permitting generation of said fragrance consists of a stationary, slotted partition means above said tray means, and a slotted member above said partition means slidable between a position blocking the slotted openings in said partition means to prevent generation of vapors and a position unblocking said openings to permit generation of said vapors.
Claim 6
Dependent Claim
192 words
Apparatus for imparting a pleasant fragrance to the air within a vehicle having a dashboard comprising housing means fully enclosed with a vent opening, bracket means for supporting said housing means below said dashboard with said vent opening facing into the interior of said vehicle, fan means within and at the rear of said housing means for blowing air through said vent opening into the interior of said vehicle, slide tray means open at the top for containing a material which upon evaporation has a pleasant fragrance, means within said housing means for accommodating said slide tray means beneath said vent whereby air movement generated by said fan means passes over said tray causing evaporation of said material, said housing means converging downstream of said fan means to increase velocity of the air flowing over said material whereby enhancing the rate of material evaporation, means above said tray means for selectively blocking or unblocking exposure of the interior of said tray means to said air movement thereby permitting air flow with or without generation of said fragrance, and switch means located on said housing means for controlling operation of said fan means.
