ABSTRACT:
A cover for a steam radiator and for circulating air passing therepast. The cover includes a cover and blower apparatus. The cover covers the steam radiator. The blower apparatus is connected to the cover and circulates the air passing past the steam radiator. The blower apparatus includes a thermostat that is disposed in close proximity to the steam radiator, and extends therefrom to a blower fan, and activates the blower fan when the air becomes heated by the steam radiator to a predetermined temperature, which causes the air to be drawn in through intake vents in the front wall of the cover, up through an open top of the cover, into a main through opening in a bottom wall of a lid portion of the cover, downwardly out through a secondary through opening in the bottom wall of the lid portion, into an upper prismatic-frustrum-shaped funnel of the blower apparatus, into a lower prismatic-frustrum-shaped funnel of the blower apparatus, downwardly through an upper tube of the blower apparatus, into the blower fan, downwardly through a lower tube of the blower apparatus, forwardly into a manifold of the blower apparatus, and out outlet vents in the front wall of the cover.
