This invention relates to improvements in celestial globes. The invention is applicable in combination with practically any kind of celestial globe and may either be permanently '5] incorporated with a globe or used as an attachment for existing or new globes.

Celestial globes of the character referred to ordinarily show stars, planets, names, constellations and the like, on the same as they are arranged in the heavens, that is, as if seen from outside the celestial sphere. When these are viewed, however, on the globe itself, they appear in a reverse position from that in which seen in the heavens. My invention contemplates the use or arrangement of a mirror in proximity to such a globe so that portions of the globe, or the globe in its entirety can be viewed in the mirror and the stars, constellations, and the like, seen in their 1 p IIllII'OPWlll. be set as shown in Figs. 1 and 2, "70

correct positions.

Other features and advantages of my 1nvention will appear more fully as I proceed with my specification.

In that form of device embodylng the features of my invention shown in the aocompanying drawings Figure 1 is a view in side elevation; Fig. 2 is a top plan view; Fig. 8 is an enlarged view of the image seen in the mirror when viewed as shown in Fig. 1; Fig. 4 is anenlarged de tail view showing a method of illuminating the globe; and Fig. 5 is a detail 'view of the lettering and the like that can be employed.

As shown in the drawings, 10 indicates a celestial globe rotatably mounted in the meridian ring 11 which, in turn, is rotatably supported in the horizon ring 12, the latter being carried by asuitable curved support 13 on top of a standard 14.

Numeral 15 indicates a mirror, here shown as substantially semi-circular in shape, carried by the trunnions 16 on the supporting fork 17, the lower end of which, as indicated by 18, is adjustably mounted in the clamp 19. Numeral 20 indicates a thumb screw to hold the rod 18 in any desired position. The clamp 19 is provided with a pair of jaws 19 adapted to embrace the horizon ring 12 and 50 21 indicates a thumb screw for holding the Southern horizon, and so forth.

clamp 19 in any desired position on the horizon ring 12. i i

p In the form bear the shown, the horizon'ring may lettering, Eastern horizon I [15 In the practice ofthe invention, the globe may-be turned'in its mounting until it is in" the correct position considering the place on the earth occupied by the observer, the season, the timeof day or night, and so forth: For so. example, the-sphere may be turned so'that the North'Pole points to the celestial North Pole in the vicinity of thenorthstar. The' globe may also be rotated on its axis until it is inthe correct position"considering'the e5 timeof dayor night. The mirror 15 may then be set at any horizon desired. For ex-' ample, if it is desired to viewthe stars as they appear when looking toward the north, the

the eye of the observer being indicated by-22. v

This. will: give an image in-the mirror substanti'ally as shown. in Fig. 3which will be, to a ccer'tain. extent, as'the stars appear at that time and place as'viewed in the heavens n75 looking toward the north. When thus viewed, it will be seen that theglobe can berotated on its axis which will show the movement of the stars as they actually occur in the heavens. Obviously, any'otherhorizon so may be similarly viewed." For example, the mirror 15 could be set at the western horizonf to showthe appearance of the stars when 7 looking westerly. 7 When thusiviewed, also, the globe can be rotated on its axis and the185 stars will enter the field of vision in the mirror at the top and leave at the bottom, thus simulating the setting of starsin thewest.

I suggest the printing of names, wording, and the like, for example, the names of con stellations like the Big Dipper with the letters arranged backwards so that when viewed in the mirror, the names will appear correct.

If desired, the globe may be adaptedfor 05 which ca-se, the stars, as indicated by 25, and the lettering, as indicated by 26, would be open or formed of some translucent or transparent material transmitting light so that the stars, wording, and so forth, will be Visible by contrast with the surrounding opaque material 24..
