Abstract
Abstract A heat sustaining and deflecting element is provided in an occupied area required to be heated, which is adapted to be set over a heat supplying source such as a cleanly burning burner, a stove top or an equivalent electrically heated unit and which includes a hood having an open side, so constructed and arranged that a rising breathable air current, produced by convection, will be deflected and redirected substantially horizontally to occupied portions of such area, in combination with highly conductive bodies occupying fixed positions under the hood for absorbing, storing, and subsequently reradiating heat supplied by said source, for redirection by the hood.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A portable heat absorbing, heat reradiating and air deflecting and distributing unit composed of heat conductive material and adapted to be set over an extraneous heat source, which unit includes a. a supporting means; b. a hood supported thereby, which hood includes uninterrupted side, back and top portions and has a wide open bottom and a wide open front, for deflecting a rising convection current of heated, breathable air in a generally horizontal direction through the open side of the hood from bottom to top thereof where it may reach and be useful to persons occupying a relatively low portion of such space, said unit further including, largely within the hood, a series of vertically spaced, horizontal, heat absorbing and reradiating plates of progressively increasing area from bottom to top of the hood.
Claim 2
Dependent Claim
133 words
A portable heat absorbing, heat reradiating and air deflecting and distributing unit composed of heat conductive material and adapted to be set over an extraneous heat source, which unit includes a. a supporting means; b. a hood supported thereby, which hood includes uninterrupted side, back and top portions and has a wide open bottom and a wide open front, for deflecting a rising convection current of heated, breathable air in a generally horizontal direction through the open side of the hood from bottom to top thereof where it may reach and be useful to persons occupying a relatively low portion of such space, said unit further including, largely within the hood, a series of vertically spaced, horizontal, heat absorbing and reradiating plates of progressively increasing area from bottom to top of the hood.
Claim 3
Dependent Claim
25 words
A unit as set forth in claim 1 in which the heat absorbing plates are substantially circular in cross-section and the hood is substantially parti-circular.
Claim 4
Dependent Claim
70 words
A unit as set forth in claim 1 in which the supporting means, the plates and the hood top are impaled upon a common headed bolt, are spaced from one another by sleeves that surround the shank of the bolt, and are clamped together in association with the sleeves between the bolt head and a nut which is threaded onto the end of the bolt remote from the bolt head.
Claim 5
Dependent Claim
36 words
A unit as set forth in claim 3 in which the hood supporting means comprises a plurality of long, narrow crossing members, which members, mounted on the bolt beneath the lowermost disc, have coterminous downturned ends.
Claim 6
Dependent Claim
27 words
A unit as set forth in claim 4 in which the lower end of the hood is coterminous with the downturned ends of the crossing supporting members.
