SUPPORT FOR LIGHT GLOBES.

Application filed April 19,

An object of the invention is to provide a support for light globes by which a light globe may be readily applied to its support and detached'therefrom. Another object of the invention is to make it unnecessary to remove or unscrew the screws which are commonly used for the support of light globes. Another object of the invention is to provide a globe support which does not put any strain on the globe at any one place. Another object of the invention is to provide a globe support cheap to manufacture and which is readily installed upon existing types of light globes.

Other objects will appear hereinafter.

Fig. 1 is a plan view of the invention partly broken away to show certain features of construction.

Fig. 2 is a horizontal section on the line 2 2 of Fig. 1.

Fig. 3 is a plan view of one of the spring clips.

Fig. 4 is a side elevation of the clip shown in Fig 3; and

Fig. 5 is a perspective view of the spring clip shown in Fig. 4:.

Fig. 6 is a plan View of the supporting ring which supports the spring clips.

Fig. 7 is a side elevation of the supporting ring illustrated in Fig. 6.

Referring to the drawings, 1 represents a globe of the type commonly used in lighting fixtures which are supported from the ceiling of a room, and 2 indicates a support or cap for said globe. The member 2 is supported from the ceiling by any suitable means not shown and has a peripheral portion 2 which has screwthreaded apertures, into which screws 3 are screwed.

The above parts are in common usage at the present time, the screws being tightened up to retain the globe in place. It has been found that the screws become corroded after use and will not set up against the globe. Again, if the screws are tightened too much,

they often crack the globe. We have found that with the addition of a few parts we can overcome the above obstacles and provide a globe support which will support the globe for ready attachment and detachment from the supporting means 2.

Our improvement consists of applying a band or ring 5 to the upper portion of the globe 1. The periphery of the globe 1 has a 1928. Serial No. 271,311.

flange 4 which serves to secure the band or ring 5 when it is attached under the flan 'e 1, and formed integral with the band 5 or a plurality of spring members 6. Any number of these may be provided, but we find that the use of three of these will serve our purpose. The members 6 extend obliquely downward and provide a curved portion 7, an upwardly extending portion 8 and a continuation 9. The portion 9 has a horizontal extension 10, the lower portion of which has a series of teeth 11. The above parts are preferably constructed of sheet metal which is resilient. The end portions 12 and 13 of the band 5 are provided with co-operating teeth 14: in order to prevent relative movement between these members when the screws 15 have been tightened in slot 16. These screws are threaded into apertures in the end portion 13 of member 5 and the ends are pulled tightly when the band is applied to the upper portion of the globe 1, whereupon the screws 15 are tightened.

It is only necessary after the band has been aflixed as above described to the bowl or globe 1, in order to fasten the globe to its support, to press the globe upwardly into the member 2 and give to the same a slight turning movement to the right. The members 6, because of their inherent resiliency will allow a number of teeth 11 to ride over the screws 3 and will resiliently hold the teeth on the screws due to the spring tension of the members 6. To detach the globe it is only necessary to turn the same in the opposite direction. The globe is not subjected to strain at any one point, because of the fact that the band 5 supports the flange 4; at all places around the periphery of the globe. Although we prefer to construct the ring 5 and the members 6 of brass, they may be constructed of any suitable material and the members 6 may be integral with the member 5, as illustrated, or they may be attached thereto by any suitable means, such as rivets 0r screws.

In order to hold the globe while the same is being cleaned or while a new lamp is being inserted, we have shown a chain, one end of which is attached to the member 2 and the other end of which is attached to the band 5.

Although we have described the lamp as one which is commonly supported from the ceiling of a room, it will be understood that We do not desire to be limited to this use, but desire to use devices embodying our invention in any place Where it may be applied.

We claim:

1. A support for a lamp globe comprising a cap, a plurality of supporting members ex tending from said cap, a globe, a plurality of arms mounted on said globe and means consisting of a plurality of stepped teeth co-operating With said supporting members for placing said arms under tension.

2. A support for a lamp globe comprising a cap'having a peripheralportion, a plurality of supporting members extending from said cap, a lamp globe, spring arms attached to said lamp globe, and extensions on said spring arms, said extensions extending substantially parallel With the periphery of said cap and having raised portions thereon co-operating Wltll SEtlCl supporting members for placing said spring arms under tension.

In testimony whereof We have hereunto set our hands this 16th day of April, A. D. 1928,

GILBERT GREEN. GEORGE BOOTH.
