The Cram"s Deluxe with an Automatic Daily Sun Ray Indicator globe was first patented in 1936 and an instant success with educational facilities. This globe aided in the demonstration of the relationship of the elliptical orbit of the earth to the sun. Displaying the point at which the Sun's rays are hitting the earth by setting the pointer on the season indicator on the base of the globe while automatically displaying day and nighttime periods by using a ferule, at any given point.
