This invention relates to a focusing mirror adapted for use in solar heating apparatus, and to mechanism for directing the mirror toward the sun. It is one object of my invention to provide an improved mirror for such purposes so designed that a mirror of large size may be easily and economically constructed and that the curvature and focal length of the mirror may be readily adjusted to suit operating conditions. Another object of my invention is to provide improved mechanism for directing the mirror toward the sun and for automatically maintain the mirror in such adjustment. To the accomplishment of this purpose, I provide means for correcting both vertical and horizontal deviations from the true direction. I also provide automatic means for resetting the mirror between the setting and the rising of the sun.
