The present invention comprises a portable ventilation system which can be incorporated into caps, hats or other conventional headgear. An aperture is formed in the brim or front section of a hat or cap which is adapted to receive the body of the ventilating apparatus. A direct current motor is installed at the center of the mounted body, the shaft of the motor being directly coupled to a multiple bladed impeller. A directional visor is mounted below the impeller and in juxtaposition to the user's face for directing the flow of air resulting from rotation of the impeller. The DC motor is powered by a portable battery pack. Interconnection between the motor source for the present invention and the battery pack allows the hat or cap upon which the present invention is mounted to be removed.

1. A ventilating apparatus for mounting upon head gear comprising: (a) a cylindrical body having upper and lower ends; (b) a circular flange secured to the lower end of said cylindrical body about the axis of said cylindrical body, said flange having a circumference which is larger than that of said cylindrical body; (c) frictional securing means disposed about the outer surface of the cylindrical body for securing the head gear adjacent said circular flange; (d) a rotary power source coupled to the cylindrical body along the axis thereof; (e) a multiple bladed impeller coupled to the rotary power source and adapted to rotate about the axis of the cylindrical body; (f) direct current power means coupled to the rotary power source; (g) a first semicircular deflection member having a radius which is substantially equal to that of the cylindrical body, said first deflection member depending downwardly from the lower end of the cylindrical body; (h) a second deflection member integral with the first deflection member opposite the cylindrical body, said second deflection member being disposed at an obtuse angle with respect to the first deflection member; and (i) a third deflection member pivotally coupled to said first deflection member, said third deflection member being adapted to adjustably deflect the axial flow of air from said multiple bladed impeller. 2. A ventilating apparatus as defined in claim 1 including a circular grid secured to the lower end of the cylindrical body adjacent said circular flange and being intermediate the first deflection member and the multiple bladed impeller.
