My invention relates to Solar heating ap from the line of incidence of this median line paratus and it has for its object to provide with its reflector to the pipe 17 being, in the an apparatus of this kind which will be of case of each of the six lenses, the same. simple and efficient construction. It Will be clear from the description given 60 5 To these ends I have provided a solar heat above that with the group of lenses disposed ing apparatus having the peculiar features perpendicularly to solar rays, those rays of construction and mode of operation set passing through each lens will be condensed forth in the following description, the novel and directed upon the reflectors, and thence features of the invention being particularly directed, still converging to a focal line at 85 O pointed out and defined in the claims at the the pipe 17. The middle lens 4 is constructed close thereof. So as to focus directly upon the pipe 17. It In the accompanying drawings: will thus be clear that if each lens collects Figure 1 is a transverse vertical sectional and delivers upon the pipe a given amount of view of a solar heating apparatus constructed heat, the total heat delivered to the pipe 17 70 5 in accordance with my invention.
