Abstract

717,293. Globes. MILTENBERGER, F. Aug. 14, 1952 [Aug. 16, 1951], No. 20429/52. Class 146(2) A terrestrial globe for illustrating the illumination of the earth by the sun in the course of a year and throughout the day consists of a transparent or translucent shell 38, 39 whose polar axis is inclined to a perpendicular on the ecliptic; the shell 38, 39 encloses an electric light 26 with a screen 25 pivoted on a perpendicular axis 23 so that one-half only of the globe is illuminated at a time. The globe is rotatively secured by a half-meridian stirrup 3 clamped to a stand 2 and the lower end of the stirrup terminates in a disc 9 carrying a ring 10 surrounding a boss 11 of a bracket 12 supporting the screen 25 adjustably carrying the light 26. By rotation of the light and screen the area of illumination of the globe can be changed from the position shown, where the surface to the left of the chain dotted line is illuminated and where rotation of the globe will not bring the north pole into the area of illumination, to the opposite position where the south pole is in continuous darkness. The rotation of the light and screen is obtained through gears 22, 20, 17 and a dial 15 calibrated into months. Two slip rings 28, 29 and spring bushes 32, 33 connect the light 26 and cable 35.
