Abstract
Abstract The heat of a fireplace is absorbed by the invention and conducted to a desired area or place instead of merely dissipating and escaping up through the chimney. The invention herein is a fireplace heater and comprises an air conductor having a heat absorbing portion and an air passage through the air conductor and air moving means for moving air through the air passage of the air conductor thereby causing ambient air to pass through the heat absorbing portion which greatly increases the temperature of the air resulting in hot air coming out of the exit opening of the air conductor. An air hole in the air conductor faces in the direction of the fire and the size of the air hole is controlled by a valve. Since air is being moved through the air conductor by the air moving means the effect of the air hole is to fan the fire and give the fire additional oxygen resulting in a hotter fire and a much more easily started fire. The invention is adaptable to various accessories so that various items can be heated or dried such as food, liquids or clothes.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
414 words
A fireplace heater, comprising: first and second heat absorbing air conduits each having an inlet and an outlet, said inlet of said first conduit receiving air into said fireplace heater and said outlet of said second conduit expelling air from said fireplace heater; a third heat absorbing air conduit interconnecting said first and second conduits, having an inlet in communication with said first conduit near the inlet of said first conduit and an outlet in communication with said second conduit near the outlet of said second conduit; a fourth heat absorbing air conduit interconnecting said first and second conduits, having an inlet in communication with said first conduit essentially at the outlet of said first conduit and an outlet in communication with said second conduit essentially at the inlet of said second conduit; said first, second, third and fourth heat absorbing air conduits defining generally a fireplace grate; first and second upright heat absorbing air conduits each having an inlet and outlet, said inlet of said first upright conduit in communication with said fireplace grate essentially at the juncture of said first and fourth conduits and the outlets of said second upright conduit in communication with said fireplace grate near the juncture of said second and fourth conduits; first and second upper heat absorbing air conduits each having an inlet and an outlet, said inlet of said first upper conduit and said outlet of said second upper conduit in respective communication with said first and second upright conduits essentially at the outlet of said first upright conduit and the inlet of said second upright conduit; third and fourth upper heat absorbing air conduits interconnecting said first and second upper conduits and each having an inlet and an outlet, said inlet and outlet of said third upper conduit in respective communication with said first and second upper conduits essentially at the outlet of said first upper conduit and the inlet of said second upper conduit respectively, said inlet and outlet of said fourth upper conduit in respective communication with said first and second upper conduits essentially at said inlet of said first upper conduit and said outlet of said second upper conduit; said first, second, third and fourth upper heat absorbing air conduits defining a plane located generally above said fireplace grate and supported by said first and second upright conduits; air moving means in communication with said inlet of said first heat absorbing air conduit for the circulation of air through said fireplace heater.
