8 Claims;

This invention relates to the mounting of globes or spheres but more particularly to the mounting of illuminated transparent or translucent hollow globes of the type frequently covered with terrestrial or celestial maps.

An object is to produce a new and improved mounting for a globe particularly of a globe made up of two hollow sections the abutting edges of which are relatively smooth but free from overlapping portions.

AnOther object is to produce an illuminated globe having the new and improved features of construction, arrangement and assembly hereinafter described.

For purposes of illustration but not of limitation, an embodiment of the invention is shown on the accompanying drawing in which Figure 1 is a perspective view of a globe and its standard;

Figure 2 is an enlarged sectional elevation of the globe showing the structural mounting features therefor; and

Figure 3 is an enlarged plan view partly in section of the interior of the globe with the upper section or hemisphere removed.

The illustrated embodiment of the invention comprises an illuminated globe having a standard II! on the top of which is a laterally extending rigid bracket arm II on which the globe I2 is mounted. The globe I2 is made up of hollow sections which in this instance are shells 0r hemispheres I3 and I4, the abutting edges of which are relatively smooth and free from overlapping portions. The standard II) and bracket arm II are formed with hollow bores to receive the electric light cord I5. A switch Ila is carried by the bracket arm II and is suitably connected to the leads I5.

Communicating with the bore in the bracket arm II is a tube I6 which is in screw thread engagement with the arm I I and projects outwardly therefrom at substantially right angles. Fitting over the outside of the tube I8 is a sleeve I1 provided with an outwardly extending flange or collar l8 on its lower end. The collar I8 engages an outwardly extending boss I9 on the upper side of the bracket arm II thereby providing a bearing for the collar I8 to enable it to turn freely relative to the bracket arm. The lower globe section I4 is provided with an opening to provide a relatively snug fit with the sleeve I! so that the globe section I4. rests against the collar I8. The sleeve I! may be of any suitable sheet material such as sheet metal and struck from the walls of the sleeve is a pair of fingers 20 which are bent downwardly into engagement with the inner surface of the globe section I4 to cooperate with the collar I8 for holding the globe section or hemispheres I4 in clamped relation.

The upper end portion of the tube or post I6 is screw threaded and receives a nut 2! which can be screwed down against the upper end of the sleeve I'I thereby securely to hold the sleeve and the hemisphere I4 in position but still enabling the sleeve I1 and hemisphere I4 to turn or rotate about the post I6. Suitably mounted on the extreme outer end of the post I6 is an electrical socket 22 to receive a lamp bulb 23. It will be apparent that in view of the assembly, any ordinary type of lamp bulb may be employed of the desired intensity and eliminating the necessity of using an elongate tubular lamp bulb which in view of assembly problems, has been widely used for this purpose.

Suitably mounted on the upper or inner end of the tube I1 is a bracket having a series of spaced inwardly and laterally curved arms 24 which are relatively narrow and which terminate at their outer ends near the mouth or open end of the globe section I4. The inner ends of the arms are integral with a disc 25 which in this instance is in screw threaded engagement with the sleeve IT. The outer ends of the arms 24 are integral with a ring 26 and extending radially outward from the ring 26 are four equi-distantly spaced pins 21, the ends of which are screw threaded to receive nuts 28 disposed on opposite sides of the ring and enable the pin to be longitudinally adjusted toward and away from the globe.

Connected to the outer end of each pin 21 is a block or foot 29. In this instance, the feet 29 are in the form of plastic blocks of material such as Lucite which is translucent and the outer face 30 of each foot 29 is curved to conform to the inside curvature of the globe sections. As shown on Figure 2, each ,foot engages a portion of the globe section I4 and also a portion of the globe section I3. As shown, approximately half of each foot engages each of the globe sections and in the first instance each foot is adjusted into snug intimate contact with the globe section l4 so that a portion of each foot projects beyond the free edge or mouth of the globe section [4. This arrangement enables the globe section I3 to be fitted properly upon the globe section l4 and enables the section I3 to be retained in the desired position relative to the section I4 so as totform a substantially smooth and unbroken exterior surface for the globe. At the same time it will be manifest that the globe section l3 can be readily and conveniently removed from the section I4 as desired and replaced thereupon without difiiculty.

In this instance, a wire yoke 15! has outwardly bent end portions which are attached to the ring 26. The yoke extends well within the globe section l3 and has an outwardly projecting stud 32 which projects through an opening in the globe section 13. A disc-like nut 33 engages the stud 32 on the outside of the globe section l3 and holds this hemisphere in the desired position.

From the above description, it will be manifest that the two sections or hemispheres I3 and I4 making up the globe 2, can rotate as a unit about the post or tube I 6 which is held stationary to the bracket arm I l Instead of employing the bracket arm II, it is manifest that the globe can be mounted in a full meridian ring or a semi-meridian ring. Whenever it is necessary to inspect or replace the lamp bulb 23, the globe section or hemisphere Hi can be removed from the section 14 by removing the nut 33 and lifting the section l3.

It will be manifest that the blocks or feet 29 enable the globe sections to be made inexpensively and free from overlapping joints which are very difficult to produce with any degree of accuracy and exactitude. A feature of importance resides in the provision of an illuminated globe in which practically the only dark spot is in the region of the outer end of the tube H. The light from the lamp bulb is sufficient properly to illuminate the remainder of the globe and the plastic feet or blocks 29 are such as to permit passage of light so as to properly illuminate the abutting surfaces of the hemispheres. The globe G2 which may be of glass or other suitable translucent or transparent material, may be covered with a terrestrial or celestial map which will be satisfactorily illuminated.

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