One of theiimportant features of this invention resides in the means for joining the hemispherical sections in a manner that will produce a satisfactory structure and prevent transverse or rotational movement of one hemispherical section relative to the other. applied to the edges of the sections before they are brought together in abutting relation, but

there are many instances where solely such means have been found to be insufficient for holding the parts together. For example, the adhesive is not always immediately effective, the abutting edges often do not make a perfect fit, or the adhesive becomes ineffective under certain condition or' I have found'that the assembly can be greatly simplified and the joint improved if a series of mounting members 20 are placed'at spaced-apart portions all around the meeting edge walls of For the purpose of I3 extends transversely across the Ordinarily, an adhesive is More or less than three I tabs may be formed and these may bebent so that they extend alternatively in oppositdire'c tions perpendicularlyVfro-m the bodyiportionwto form oppositely facing channel sections for re ceiving the edge Wall portions' of eachhemis pherical section when brought into assembled:

ssr tsaro ate dy tess nr s p sm ridian ring. The mounting, glget congprises g rigid disc member 50 adapted, with a minimum of friction, slidably to engage the under side of the flange 35 and having a central cylindrical section or block 5| that telescopes a short distance into the sleeve 34. A nipple 52, threadably secured to the section 5|, extends into the lobe and mounts a socket 53 for the illuminating bulb 54. The electrical cord 55 for the socket passes through the nipple 52 and through openings 56 and 51 to the current source. For mounting the bracket in a manner to prevent relative rotational movement, a boss 60, havin a threaded opening on its under side, depends from the bracket and seats in the groove 13, in which position it is locked by the set screw l4 engageable therewith.

The operation of the globe will be evident from the description and drawings. Sufiice it to say that the globe turns relative to the meridian ring while being supported on the mounting bracket. The globe may be dismounted merely by loosening the set screw l4 and sliding the globe with the mounting bracket sidewise until the meridian ring is cleared. If it is desired to remove the entire globe, the assembly may then be lowered until the knob 4| clears the recess l2, or if it is only desired to remove or replace the illuminating bulb, the bracket may be removed as a unit with the globe and attachments for replacement or repair.

From the description, it will become evident that I have invented a new and improved illuminated globe assembly having simple and novel means for mounting and maintaining the hemispherical sections, from which the larger sized globes are manufactured, in their assembled relation and for removably mounting the assembled globe in an arcuate support by means of a mounting bracket that also forms a part Of the lighting fixture. For purposes of effecting the desired assembly and mounting, relatively few and simple parts are employed thereby to enable a globe, having illuminating features, to be manufactured in any size at a relatively low cost, and to enable replacement of parts or repair without difliculty or particular shells.

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

What I claim is:

1. An illuminated globe comprising a pair of hemispherical shells, each havin an aperture in a position to be diametrically opposed when the sections are together in the form of a globe, a bearing post, means adjustably mounting said bearing post in one of said apertures, said mounting means comprising a pair of nuts threadedly engaging the bearing post, one nut being disposed within the globe and having a centrally recessed portion corresponding in size to that of the opening through the hemispherical shell, notches in said nut for enabling turning movement to be efiected from without the globe, the other nut being disposed outside of the hemispherical shell, 9. central post on said latter nut extending through said opening and fitting within said depressed portion in the assembled relation, outwardly flared portions on said nuts for gripping the adjacent hemispherical shell wall therebetween when in assembled relation, bushing means stationarily mounted in the other aperture, an internal support connecting said bushing means with said bearing post for holding said hemispherical shells together, an arcuate mountin for the globe having a notch for receiving said bearing post, a combined lamp socket and bushing engaging support for mounting said lamp socket internally of the globe and rotatably supporting the lattenand means for detachably securing said support to said mounting.

2. An illuminated globe comprising a pair of hemispherical shells each having an aperture in position to be diametrically opposed when the sections are together in the form of a globe, a bearing post, means for adjustably mounting said bearing post in one of said apertures, a sleeve corresponding diametrically to the opening through the hemispherical shell, an annular flange on the sleeve adapted to seat against one wall portion adjacent the opening, another sleeve telescoping within said first sleeve, an annular flange on said latter sleeve for engaging the opposite wall portion adjacent the opening, means for locking the sleeves in their telescoped position thereby to grip the hemispherical shell therebetween, an internal support connecting one of said sleeves with said bearing post for holding the hemispherical shells together, an arcuate mounting having a notch for receiving said bearing post, a combined lamp socket and bushing engaging support for mounting said lamp socket internally of said globe and rotationally supporting the latter, and means for detachably securing said support to said mounting.
