Abstract
Abstract A radiator has a plurality of vertical pipes with longitudinally co-extensive radiating surface extensions. The extensions are generally T-shaped in cross-section with the base of the T being joined to the pipe. Extensions are joined at opposite sides of an oval pipe. The pipes are joined by headers, and the resulting radiator has a rectangular shape with a plurality of spaced vertical rectangular members.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
In a radiator comprising a plurality of parallel conduit components connected between two manifolds, each conduit component comprising two longitudinally joined plates, incorporating therebetween a pipe for containing a heating medium, the plates extending on opposite sides of the pipe outwardly therefrom, the improved combination wherein the plates extend on opposite sides of the pipe outwardly therefrom to surfaces of the radiator and terminate in flat faces perpendicular to the plates, wherein the flat faces present substantially plane, continuous surfaces periodically cut by a narrow slot between adjacent components, and wherein adjacent pairs of components encompass substantially closed cavities for chimney-like circulation of air, each cavity contiguous with two said pipes, one on each of two opposite sides of the cavity.
Claim 2
Dependent Claim
121 words
In a radiator comprising a plurality of parallel conduit components connected between two manifolds, each conduit component comprising two longitudinally joined plates, incorporating therebetween a pipe for containing a heating medium, the plates extending on opposite sides of the pipe outwardly therefrom, the improved combination wherein the plates extend on opposite sides of the pipe outwardly therefrom to surfaces of the radiator and terminate in flat faces perpendicular to the plates, wherein the flat faces present substantially plane, continuous surfaces periodically cut by a narrow slot between adjacent components, and wherein adjacent pairs of components encompass substantially closed cavities for chimney-like circulation of air, each cavity contiguous with two said pipes, one on each of two opposite sides of the cavity.
Claim 3
Dependent Claim
20 words
A radiator according to claim 1 wherein corners of the flat faces are removed thereby providing for additional air circulation.
Claim 4
Dependent Claim
165 words
In a radiator comprising a plurality of parallel conduit components connected between two manifolds, each conduit component comprising two longitudinally joined plates, incorporating therebetween a pipe for containing a heating medium, the plates extending on opposite sides of the pipe outwardly therefrom, the improved combination wherein the plates extend on opposite sides of the pipe outwardly therefrom to surfaces of the radiator and terminate in flat faces perpendicular to the plates, wherein the flat faces present substantially plane, continuous surfaces periodically cut by a narrow slot between adjacent components, wherein adjacent pairs of components encompass substantially closed cavities for chimney-like circulation of air, each cavity contiguous with two said pipes, one on each of two opposite sides of the cavity, and wherein the two manifolds are rectangular and are each comprised of two complementary U-shaped halves, the width of each half corresponding to distance between the surfaces of the radiator and wherein corners of the flat faces are removed thereby providing for additional air circulation.
