Abstract: A system for collection of solar energy by one or more reflectors which concentrate the suns rays on liquid circulating pipes which is part of a collecting and storing system for solar heated liquid to replace or supplement usual sources of heat in heating systems. More specifically, the system comprises one or more bent, preferably parabolic reflectors pivotly mounted on black heat absorbing pipes through which liquid circulates to absorb heat energy from the sun. The reflectors and the pipes are mounted in an open space such as a building roof with adjusting mechanism to pivot and fix the reflectors in different positions. Transparent plates bridge the space between the edges of the reflectors with hooked cross straps to hold the assembly together.

Abstract: A method of making a solar reflector from a flat rectangular sheet of reflecting material into a substantially a parabolic cross-sectional shape to form a part of a solar heat collecting system wherein the reflector is supported to concentrate the rays of the sun on a pipe through which liquid is circulated including bending permanently the sheet material along its longitudinal center line to give the two half portions thereof a minor angle with respect to a horizontal plane, bending the longitudinal edges back upon themselves to form slotted hook portions along the longitudinal edges of the sheet material and bending the two half portions toward each other below the breaking point of their elasticity to receive the longitudinal edges of a translucent plate in the slots of the hook portions whereby the parts are held in assembly.
