UNITED STATES EDWIN F. GUTH, OF ST. LOUIS, MISSOURI.

GLOBE HOLDER.

Application filed November 18, 1926. Serial No. 149,066.

My invention relates to the lighting fixture art and particularly to devices adapted to receive and support in position, a globe to surround the light source.

The object of my invention is to provide a device for this purpose, of simple, strong, durable and practically inexpensive construction, which may be. quickly and easily operated and always dependable to perform the function for which it is designed.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Fig. 1 shows an exploded view of my device and a globe to be received thereby;

Fig. .2 shows a sectional view of my device and a part of a globe supported thereby;

Fig. 3 shows a transverse sectional view of the same;

Fig. 4 shows a side elevation view, in detail, of my locking ring;

Fig. 5 shows a side elevation view, in detail, of the canopy terminating in the sup porting ring I employ; and

Fig. 6 shows a modification of my locking ring in which I employ a spring, wire shaped, to function in substantially the same manner as the locking ring shown in detail in Fig. 4.

As illustrated in the drawings, my improved globe holder comprises a canopy 10, which is supported at its upper extremity by a chain 11 in the ordinary manner. This canopy is of the standard shape, and flares downwardly and outwardly. terminating at its lower end in a vertical cylindrical portion 12 having a bead at its extremity. As far as this construction concerned, my canopy ditters very little from many canopies in general. use. it being my desire to utilize the standard term of 'anopy in constructing my globe holder. To this end, I punch or stamp one or more tongues out of the vertical cylin' drical wall of the portion 12', as indicated atlb. and force the punched-out portion 14 in wardl v and downwardly to form the tongues 15. These tongues 15 are preferably curved to conform to the curvature of the lip of the globe 17, and. should be only on one-half of the circumference of the vertical cylindrical portion 12 of the canopy 10. so as to permit the insertion of the globe 17 in the manner indicated in Fig. 1. I form a plurality of apertures 18 in the vertical cylindrical wall 12, on that side of the canopy 10 opposite the resilient tongues 15. The globe 17 is locked in the canopy 10 by means of the ring 19, which is formed to telescope the outside of the vertical cylindrical portion 12 and extend down until it contacts with the bead at the lower edge of the canopy 10. I provide a plurality of internally extending lugs on the inner wall of this ring 19, which are located so as to register with the openings 18 in the vertical cylindrical wall 12, and are also curved to correspond to the curvature of the lip of the globe 17.

In my modified form, illustrated in Fig. 6, I construct my locking ring of a heavy spring wire 22, the ends terminating in inwardly extending curved hook members 23, designed to project through their respective openings 18 and engage the lip 16 of the globe 17. By this construction, the locking ring of my device may be applied without inserting it over the canopy as the fixture is being installed, for the spring wire may be forced open to pass across the enlarged central portion of the flangedring 12 after all the other parts, including the lobe, have been placed in their final positions. In practical operation, the globe 17 is tilted sidewise, as shown in Fig. 1, and the lip there of placed above the lugs 15. The globe is then moved into its normal position within the ring 12. The locking ring 19 is then brought down, the lugs 20 passing through their respective openings 18, snapping over and engaging below the lip 16 of the globe 17, at points opposite to the lugs 15. The locking ring 19 is then forced downwardly, over the wall of the flanged ring 12 and by friction, and the resiliency of the metal furnishing a spring tension on the tongue, the globe is held firmly in position, locking the assembled parts of my device in their proper functioning position. \Vhen it is desired to remove the globe 17, this is accomplished by the operator placing his thumb, or fingers, against the outwardly extending lug 21 and lifting on it, which operates to snap the ring 19 out of engagement with the vertical cylindrical wall 12. and by tilting the globe 17, as shown in Fig. 1, it can be detached from the resilient tongues 15.

It is not essential the supporting lugs be formed by cutting and punching the metal as I have described, but I prefer such, and therefore do not desireto be limited in the scope of my protection except as outlined in the appended claims. t i

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is:

1. A holder for lighting globes comprising a canopy having a vertical Cylindrical portion, a plurality of inwardly extending arcuate tongues struck out of said portion, there being an opening in said portion equidistant from said tongues, a securing ring Which fits over said vertical cylindrical. portion, a similar tongue formed thereon, said tongue fitting said opening.

2. A support for globes, comprising a canopy having a plurality of openings formed in its wall adjacent its lower edge, an inwardly extending resilient tongue formed on the Wall of said. canopy adjacent its lower edge, a ring adapted to telescope the outer Wall of said canopy, inwardly extending resilient tongues on said ring which register with said openings, said tongues being adaptedv to project; inside of the canopy and engage the lip of a 3. A support for globes, comprising a canopy havin g a plurality of openings formed in its all adjacent its lower edge, resilient means on the inner Wall of said canopy ad apted to engage the lip of a globe, a ring adapted to telescope the outer Wall of said canopy, and resilient means on the inner Wall of said ring adapted to register with said openings and engage the lip of the globe to he supported.

4. A support for globes, comprising a can opy having a plurality of openings lira-med in its Wall adjacent its lmrer edge, resilient means on the inner wall oi. said canopy adapted. to engage the lip of a globe, a ring adapted to telescope the outer wallv of said canopy, and resilient means on the inner wall of said ring adapted to register with said openings and engage the lip (31? the globe to he supported, sanl means cantor-wing to the curvature oi the lip of said globe.
