ILLUMINATED GLOBE Ffiled Feb. 24, 1940 Fayhano ff flap/er Patented Apr. 7, 1942 I UNITED STATES PATENT OF FI'CE 1 Claim.

This invention relates to illuminated globes such, for example, as terrestrial and celestial globes, which are mounted on a standard or other suitable support and are lighted in such manner that the exterior surface of the globe is illuminated, thus facilitating the examination thereof, and an object is to produce a new and improved illuminated globe of the above character in which the lamp is disposed outside of the globe and the arrangement being such that the globe is satisfactorily and efiiciently illuminated and the cost of the assembly being materially reduced. I

For purposes of illustration but not of limitation, an embodiment of the invention is shown on the accompanying drawing in which the figure is a side elevation, partly in section, of an illuminated globe and supporting standard therefor.

The illustrated embodiment of the invention comprises a standard having a base l carrying an upstanding yoke having arms I l and I2. Formed in the standard is a, vertically disposed opening [3, the upper portion of which flares outwardly, the opening or socket l3 being open ended. Disposed within the opening 13 is a bracket M to receive an electric light bulb I 5, the wires l 6 for the bracket l4 leading through the bottom end of the opening l3 and having a plug 11 of the usual character at the opposite end thereof. For directing the light rays upwardly is a reflector I8 arranged within the opening l3. In the outer end of the opening I3 is a lens l9 which is suitably held in place by a ring 20.

Carried by the outer ends of the yoke arms H and I2 by rivet pins 2| is a meridian ring 22 and carried by the meridian ring 22 is a globe 23, the walls of which are of glass or other suitable translucent material. The globe 23 is mounted for rotative movements within the ring 22 by diametrically

opposed supports

24 and 25, one of which is preferably releasable to enable the globe to be assembled as will be readily understood by those skilled in this art. The globe 23 is covered by a series of gores 26 which may contain any suitable pictorial illustration such, for example, as a terrestrial or celestial map. The gores 26 are preferably of relatively thin sheet material of translucent character as, for example, relatively thin parchment paper.

It will be manifest that the arrangement is such that the form of lens I9 is not critical, except that it shall confine the directed rays to the globe surface, thereby to obviate stray rays beyond such surface which would cause glare interfering with reading of the indicia, and in order fully and satisfactorily to illuminate the globe. The light rays penetrate through the translucent gores 26 and through the walls of the globe 23 in order to illuminate the outer surface of the globe, thereby to facilitate the examination of the indicia on the gores In this manner an exceedingly inexpensive illuminated globe may be produced, eliminating the costly features normally attendant to an illuminated globe in which the lamp is positioned inside of the globe. It will be recognized that the intensity of the light rays must be suflicient to penetrate through the gores as well as the walls of the globe in order to light up all portions of the globe. An important advantage of the above described arrangement resides in the fact that substantially'the entire surface of the globe is illuminated and in such manner that examination thereof can be readily made. This is a decided improvement over illuminated globes which obtain their illumination from a lamp disposed inside of the globe because in'such structures, a dark spot exists where the lamp enters the globe.

It is to be understood that numerous changes in details of construction, arrangement and opera tion may be effected without departing from the spirit of the invention especially as defined in the appended claim.

What I claim is:

The combination of an indicia-carrying globe of translucent material, a support for pivotally mounting said globe in spaced relation thereto, said globe support formed with a recess, a light source mounted in such recess to be shielded thereby from an observer, and a lens mounted in the open end of such recess for confining the directed light rays to the maximum area of the globe surface which is presented to said light source.
