MOUNTING DEVICE FOR ILLUMINATED GLOBES Filed Jan. 21, 1950 INVENTOR. Raymond A. Dup/er mm a. 2M

A TTORNE Y Patented Nov. 24, 1953 UNITED STATES PATELNT attain QFFICE MOUN TIN G DEVICE FOR ILLUMINATED GLOBE S 1 Claim. 1

This invention relates to the mounting of globes such, for example, as globes containing terrestrial or celestial maps or other indicia, or plain globes, and an object is to produce a simple and efiicient mounting device for use with globes which can be readily and conveniently applied to an apertured portion of the globe enabling the globe to be mounted, for example, on a suitable supporting post or the like or in the case of an illuminated globe enabling the same device to be employed but in association with a conveniently mounted guide element to receive the usual lamp supporting socket thereby enabling the same grommet-like device to be employed either for an illuminated globe, in which case the lamp support guide is employed, or for a plain or unilluminated globe, in which event the grommet-like device is used alone, thereby substantially reducing the cost of mounting these globes and producing a device which is adapted for use either with a plain globe or with an illuminated globe.

Other objects and advantages reside in details of construction and arrangement of parts, and for purposes of illustration but not of limitation, an embodiment of the invention is shown on the accompanying drawings, in which:

Figure 1 is a fragmentary side elevation of a globe or sphere with translucent walls and show ing the grommet with which a guide device is associated for use in connection with an illumihated globe:

Figure 2 is an enlarged transverse sectional view substantially on the line 2-2 of Figure l; and

Figure 3 is an exploded view in perspective showing the globe engaging grommet and the spring arm, guide device which may be attached to the grommet when used in connection with an illuminated globe.

The illustrated embodiment of the invention comprises a sphere or globe, the walls I B of which in this instance are of transparent or translucent material such as glass, Lucite or the like. As shown, the sphere is covered with a map I! which may be a terrestrial map although the covering and the indicia thereon may be of any desired character. The globe in this instance is mounted upon an arcuate support or semimeridian ring i2 to which it is suitably connected by a support device [3 at the upper end enabling the globe or sphere to be rotated about its axis. The mounting for the semi-meridian ring [2 is not shown but reference is made to my Patent 2,127,249, dated August 16, 1938, and entitled Illuminated Globe Mounting which shows one form of standard or support for the arcuate support l2.-

It is a desideratum to provide a mounting means for a globe or sphere of this character which can be used when the globe is to be illuminated by means of a lamp projecting inside of the globe, or for use in connection with a plain or unilluminated globe. As shown, the globe is provided with an aperture [4 which is diametrically opposed to the support device I3 and fitting inside of this opening is a grommet !5 in the form of a metallic disc-like annulus It for engaging the outer surface of the globe around the aperture l4 and an integral relatively short tube 5! which projects inside of the globe and abuts against the edge wall of the aperture Id. The tube H is provided with a plurality of apertured tabs H} which are at all times disposed substantially in planes parallel to the axis or center of the grommet l5. The tabs I8 are bent outwardly and downwardly against the inner wall of the globe and cooperate with the flange or annulus It to retain the grommet in place. Thus when the device is used with a plain or unilluminated globe, the grommet is inserted into the aperture of the globe, the tabs i8 are bent inwardly thereby effectually retaining the grommet in position, the apertured tabs I9 remaining in their inwardly extending normal position.

In the event the mounting is used in connection with an illuminated globe which employs an elongate electric lamp 20 which is connected to a tubular support 21 which extends through the grommet [5, some support is necessary for the lamp receiving support or socket member 2!. For this purpose, a metallic band 22 is employed having a series of downwardly extending spring arms 23. The lower end 2 5 of each spring arm 23 curves outwardly and terminates in a reduced extension 25 which is shaped to conform to the rectangular aperture 26 in each of the apertured tabs 15. As shown, there are four spring arms 23, one being provided for each of the apertured tabs :9. In use the guide element 22 is forced through the grommet i5 until the reduced extensions 25 enter the apertures 25 in the tabs or lugs 52, whereupon the guide is held in the desired position of use. It will be understood that the arms 23 are sufficiently springy to enable the extensions 25 to enter the apertures 25 and retain the assembly in position of use.

From the above description, it will be apparent that I have produced an exceedingly simple and inexpensive rnountim which can be used either for a piain or unilluminated globe or for an illuminated. globe by merely the addition of the spring armed guide device which can be readily and com veniently mounted in position oi use. This obviates the necessity of having a special mount ing for illuminated globe and another mounting for use in connection with a plain or unilluminated globe.

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

What I claim is:

A mounting for a lamp within a globe having series of tabs integral. with said tube adapted to be bent against the inside of the globe for retaining the annulus in place, tabs integral with said tube coaxial with said tube having apertured ends adapted to be disposed within the globe, a guide member comprising a band of smaller diameter than said annulus, spring legs integral with said band and depending therefrom, and outwardly inclined end portions on said legs adapted to be flexed into the apertures in said last tabs thereby to hold said guide member in position of use in alignment with said annulus.
