R. R. DUPLER ILLUMINATED GLOBE STRUCTURE Filed April 11,1944

' INVENTOR. B ymwz RDupZer W7 MAW ATTORNEY Patented Dec. 30, 1947 UNITED,- STATES A N 3 Claims.

This invention relates to-illuminated globes such, for example, as globes having a source of light on the inside and the outside covered by translucent terrestrial or celestial maps, and an object is to produce a new and improved illuminated globe structure in which the globe is in the form of two hemispherical shells, the globe being supported by either a full meridian ring or semi-meridian ring by simple and efiicient means.

Other objects and advantages will hereinafter appear and for purposes of illustration but not of limitation, an embodiment of the invention is shown in the accompanying drawings in which Figure 1 is a side elevation of the illuminated globe structure;

Figure 2 is an enlarged vertical sectional elevation of the globe and meridian ring; and

Figure 3 is an enlarged transverse sectional view substantially on the line 33 of Figure 2.

The illustrated embodiment of the invention comprises a globe in the form of two hemispherical shells l and H. The shells l0 and II are preferably of glass but may be of any suitable transparent or translucent material. In the region of the north pole the shell It is formed with an inwardly extending post l2 having an outwardly opening socket I 3 which may be of any desired shape. Fitting within the socket I3 is a block I4 which may be of metal, and adhesive such as glue may be employed for fastening or cementing the block within the socket. Integral with the block I 4 and projecting outwardly therefrom is a cylindrical post l5 which extends into an aperture or socket formed in a full meridian ring Hi. It will be observed that the outer side of the block I is flush with and conforms to the adjacent peripheral surface of the shell In.

In order to insure that the block will be held securely in position, it is provided with a screwthreaded shank I1 which extends through an aperture in the bottom wall of the socket l3. A nut l8 engages the shank I! to hold the block securely in place.

The two shells l0 and II are secured together at their abutting edges by a strip I9 of trans parent adhesive tape commercially known as Scotch tape. Obviously the light rays from the inside of the globe pass through the Scotch tape and when the same is covered by a map or some decorative design, the same will be obscured from view and will not be noticeable. Tape of this character possesses substantial strength sufficient to hold the two shells in the desired relation.

At the opposite end .or south pole of the globe is a combined lamp bracket and. globe. -supporti which has a block 20 of polygonal cross section.

The block 20 fits a notch 2| on the inner side of the meridian ring l6 and this notch is open at opposite sides so that the block may be slipped laterally in one direction or the other as desired. A screw 22 extends through the opening in the meridian ring and threadedly engages the block 20 thereby to hold the same in the desired position. Mounted on the block 20 is a ring 23 which extends into and fits an opening formed in the shell II. On the lower end of the ring 23 is an outwardly extending flange cap 24 which engages the outer side of the shell H in the region adjacent to the edge of the'hole.

Suitably secured to the ring 23 and projecting inwardly therefrom inside of the globe are fingers 25 which support a lamp socket 26 carrying an elongated lamp bulb 21. The wiring 28 for the lamp passes through an opening in the side of the block 20 and thence upwardly between the fingers 25 to the socket 26.

From the above description it will be manifest that I have produced an exceedingly simple and practical globe assembly enabling the use of hemispherical shells which can be more readily produced than the one-piece globe. The shells can be readily molded and the attaching or mounting parts quickly and easily applied. When it is desired to detach the globe from the ring IE, it is merely necessary to loosen the screw 22 and then bodily shift the block 20 and its adjacent parts laterally clear of the notch 2!. This rocking action is possible due to the mounting of the post IS in its aperture or socket. Thereafter, the lamp bulb 21 can be readily replaced if nec essary. The structure is such that it can be simply and inexpensively produced and the assembly problems reduced to a minimum.

It is to be understood that numerous changes in details of construction, arrangement and operation may be efiected without departing from the spirit of the invention especially as defined in the appended claims.

What I claim is:

1. Illuminated globe structure comprising a globe in the form of a pair of hemispherical shells, means for adhesively joining said shells, one shell having an inwardly extending socket, a block within said socket having an outwardly projecting post, means for securing said block within said socket, an arcuate mounting for said globe having a socketed portion to'receive said post, said arcuate mounting having a notch arranged diametrically opposite said socketed portlon, opposite sides of said notch being open, a combined lamp socket and globe support mounted in said notch, and a fastener for detachably securing said support to said mounting, whereby upon loosening said fastener, the support may be bodily moved from said arcuate mounting and then the post slipped out of its socketed portion.

2. Illuminated globe structure as claimed in claim 1, wherein the, means for. securingtheblock in the socket comprises a threadecli'shank depending from said block through an aperture in the bottom of said socket, and a nut on the inside. of said shell engaging said shank.

3. Illuminated globe structure as: claimed". im'

claim 1, in which said combined lamp socket, and. globe support comprises a polygonarblock fitting v said notch for preventing turningofrthexhlock; a flanged ring on said block with the flange there-., of engaging the outer side of the respective shell and the ring extendinginto an opening in the shell; a lamp :socket on said ring. and projecting inside of the globe, and a screw in said arcuate mounting in screw-threaded engagement with said polygonal block.
