Abstract
Abstract A solar heat collector having a collector element made from interconnected tubular members, each of which is provided with a transverse baffle, the baffles have openings forming spillways over which heat exchanging liquid passes. The collector element is preferably made from a plurality of tandem arranged sheet metal soft drink or beer cans, the ends of certain cans being removed before the cans are assembled. One or a plurality of collector elements are disposed along an incline such as a roof and a pump feeds liquid to the upper end or ends of the inclined collector element or elements to cascade down through each element and be heated by heat absorbed into the metal from the sun's rays. The heated liquid is then fed through a pipe or pipes from the lower end of each collector.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A solar collection comprising, a plurality of metal soft drink or beer cans of the type which have body portions and tops across the ends of said body portions, the tops having openings therein formed when the cans were opened, each of said cans having an open bottom received by the top of the next adjacent can for forming a series of connected juxtaposed tandem coaxial cans defining successive compartments of a tubular body closed throughout its length and in which said tops of said cans form longitudinally spaced generally radially extending baffles which, when said tubular body is inclined with said openings being respectively spaced above the lowermost inside portions of the adjacent body portions, successive spillways for liquid fed by gravity from the uppermost can of said series and permit the liquid to collect in successive compartments while cascading down through said successive compartments.
Claim 2
Dependent Claim
146 words
A solar collection comprising, a plurality of metal soft drink or beer cans of the type which have body portions and tops across the ends of said body portions, the tops having openings therein formed when the cans were opened, each of said cans having an open bottom received by the top of the next adjacent can for forming a series of connected juxtaposed tandem coaxial cans defining successive compartments of a tubular body closed throughout its length and in which said tops of said cans form longitudinally spaced generally radially extending baffles which, when said tubular body is inclined with said openings being respectively spaced above the lowermost inside portions of the adjacent body portions, successive spillways for liquid fed by gravity from the uppermost can of said series and permit the liquid to collect in successive compartments while cascading down through said successive compartments.
Claim 3
Dependent Claim
31 words
The solar collector defined in claim 1 wherein the bottom end portions of said body portions respectively overlap the upper end portions of the body portions of the next adjacent cans.
Claim 4
Dependent Claim
48 words
The solar collector defined in claim 1 including an additional soft drink or beer can having a top in an opened condition and a body portion and a bottom, said additional can being connected to the open end of the endmost can at one end of said series.
Claim 5
Dependent Claim
52 words
The solar collector defined in claim 1 including an additional soft drink or beer can have a body portion and a bottom and in which the top has been removed, and the open upper portion of said additional can is connected to the top portion of the endmost can in said series.
Claim 6
Dependent Claim
59 words
The solar collector defined in claim 3 including a second additional soft drink or beer can having a body portion and a bottom and in which the top has been removed and the open upper portion of said said second additional can is connected to the top portion of the endmost can at the other end of said series.
Claim 7
Dependent Claim
17 words
The solar collector defined in claim 5 including nipples protruding through the bottom of each additional can.
Claim 8
Dependent Claim
37 words
The solar collector defined in claim 1 wherein said tops are provided with openings extending from the central portion outwardly toward an edge portion and wherein each of said openings is aligned in said series of cans.
