No. 13486.—22nd March, 1901.—SOLAR MOTOR COMPANY, a corporation organized under the laws of the State of New Jersey, and doing business at 186, Devonshire Street, Boston, Massachusetts, United States of America, Manufacturers (assignees of Aubrey George Eneas, of 186, Devonshire Street, Boston aforesaid, Gentleman). Improvements in solar generators.

Claims.—(1.) A solar generator comprising a reflector, a support therefor, and means for changing the position of said reflector, said reflector having a conical form open at top and bottom, being truncated above its apex at such a distance as to provide a relatively large opening as and for the purpose described, and steam-generating apparatus located in the focus of said reflector. (2.) A solar generator comprising a reflector in the form of a cone, a support therefor, and means for changing the position of said reflector, said reflector having a truncated form open at top and bottom, and made up of a multitude of facets each curved very slightly with respect to two axes, and the whole having the general curvature of the truncated cone, and a boiler and water-circulation apparatus extending co-axially of said reflector. (3.) A solar generator comprising a reflector having a curved reflecting surface focussing at all points along a straight line or a focal axle, pivotal fixed supports for said reflector at opposite sides thereof for the diurnal movement of the reflector, and means for varying the angle of the focal axis relatively to the said fixed pivotal diurnal axis of the reflector, according to the declination of the sun. (4.) A solar generator comprising opposite fixed supports set in alignment with the meridian of the place, said supports containing fixed pivotal bearings at unequal heights, the axial line of said bearings extending at an angle corresponding to the latitude of the place, a reflector mounted at its opposite sides to turn on said bearings, said reflector having curved walls of the conical type described, and means for tipping said reflector so as to vary the angle of the focal axis thereof relatively to said pivotal line, and means to turn said reflector on said bearings. (5.) In a solar generator, a reflector having at opposite sides approximately vertical tracks, fixed supports, each of said supports being provided with pivotal bearings for said reflector, and connections between said pivotal supports for moving said tracks relatively to said pivotal bearings. (6.) In a solar generator, independent supports each provided with a pivotal bearing, said pivotal bearings being in longitudinal alignment, a reflector mounted on said pivotal bearings and having its centre of gravity approximately in the line of said pivotal bearings, means for shifting said reflector relatively to said pivotal bearings, said reflector being maintained with its centre of gravity in the said pivotal line in all the changing positions of the reflector. (7.) A solar generator comprising a reflector of the conical type described, automatic means for giving said reflector a diurnal movement at a uniform rate of speed corresponding to the apparent diurnal travel of the sun, and means for varying the length of time required to pass from sunrise position to sunset position, and intermediate positions, according to the different periods of the year, without adjusting the clock or controlling-device.
