Abstract A ventilator device in the form of a half dome having an open, screened face surmounting a sloping header with an internal, hinged entrance located below the header and a slotted U-tube having dual funnel shaped intakes facing in the direction of the screened face, the slotted U-tube enabling air forced therein via the funnel intakes to disperse moisture within the device to be exhausted other than through the air passageway over which the ventilator device is mounted with an opening in a vehicle to be ventilated. The ventilator device may be molded or otherwise formed, and the material of which it is made may be opaque or translucent - in the latter case providing illumination from daylight sources as well as ventilation.
A ventilator device for mounting over an opening in a moving vehicle comprising a half-dome shaped, flanged, upper member and a substantially flat, lower member juxtaposed symmetrically thereon and joined therewith, a screened opening in said upper member for admitting forced air into said device, an opening in said lower member for exhausting air from said device, a walled enclosure around said lower opening for preventing water forced into said upper opening from escaping through said lower opening, a funnel-ended U-tube surrounding said enclosure having its funnel ends extending outside said device and facing with said upper opening, and an opening in the base of said U-tube for dispersing air into said device to agitate water accumulating in said device.
