Patented June 17, 1930 UNET SATES JOSEPH HENRY HUDSON, OF BROOKLYN, NEW YORK GLOBE SUPPORT AND THE LIKE Application filed December 1, 1928- Serial No. 323,113.

This invention relates particularly to globe-supporting devices adapted for use in connection with holders having interior grooves,

The primary object of the invention is to provide a simple and easily manipulated globe-supporting device, which is adapted to to securely engage and hold a globe or the like by means of a separable deformed resilient open cylindrical coil.

.The inventive idea involved is capable of expression in a variety of forms, influenced by the form of groove in the holder and the form of neck on the globe and by the upper and lower inclinations of the sides of the coil.

The invention is illustrated in its preferred embodiment, in the accompanying drawing, in which Fig.1 is an elevational view of an open cylindrical coil C before being deformed;

Fig. 2, a plan view of the deformed coil C showing its two ends connected with each other and ready to be placed on the globe;

Fig. 3, a sectional view of a depending electric lighting fixture showing (partly in full lines and partly in dotted lines) the deformed coil C in use, this section being taken as indicated upon a line 44: of Fig. 2, the holder A, the globe B, the socket D and the lamp E 39 being no part of my invention, however;

and Fig. 41:, a broken sectional view taken similarly to Fig. 3, and showing a fragment of a metal shade in order to illustrate the adaptability of the deformed coil to different makes of grooves in holders and of necks on globes. The deformed coil can be used to connect the shade shown in Fig. 4 with the holder shown in Fig. 3, also to connect the holder shown in Fig. 4 with the globe shown in Fig.

3, also to connect a reflector with a holder having an interior groove. The globe may be of any form having a neck, and may be open at the bottom. The holder may be of any form having an interior groove, it need have 45 no ventilating holes, and it need not be attachable to a socket.

It will be observed that the deformed coil and the globe are in compression and that the holder is in tension, thus forming a truss.

In the example illustrated (see Figs. 2 and 3) the ends of the coil have been conjoined by means of the integrally-formed interlocked loops 3 and the coil has been deformed to press outwardly downward against the lower inside of the groove of the holder at deformations 1 and upwardly inward against the upper part of the neck of the globe at deformatlons 2, and to press outwardly against the middle inside of the groove of the holder at deformations 3 and at. interlocked loops formed at 3*. The deformations 2 may be midway between deformations 1 and 3, or to either side of said middle point.

The coil being easily expansible by reason of lts inherent elasticity and its capacity to flex between its deformations is stretched over the flange of the globe, whereupon the coil will constrict itself around the neck of the globe. Thus placed on the globe the coil 1s sprung into the holder by pressing one or more of the deformations 1 and 3 or at 8*, thereby quickly uniting the globe and the holder. When the globe is being positioned the polygonal form of the coil as a whole is distorted, its sides momentarily flexing and compressing their open turns, and then reflexing within the groove of the holder, thus assuring a tight fit in the holder. When it is desired to remove the globe, it is steadily pressed at any exposed portion near its neck while pressing oppositely on the holder in order to cause flexure of the deformed coil and eccentricity relative to the holder, the crescent-shaped space thereby yielded permitting the globe with the deformed coil placed thereon to be readily released.

The act of, deforming the coil stiifens it at and for a distance alongside the deformations, enabling the deformed coil to securely hold the globe in whichever direction the holder points. The deformations are shown as twelve in number inclusive of the interlocked loops formed at 3 counted as one deformation. Any desired number of deformations and any desired number of turns in the coil may be employed, the turns may be any desired diameter, the coil may be made from any suitable material, the deformations may be any shape suitable to the neck on the globe and the groove in the holder, and the interlocked loops or any suitable joint may be used anywhere in the length of the coil, however. Under the influence of heat the open turns of the deformed coil in position are free to expand in all directions independently of the expansions of the globe and of the holder. The springiness left remaining in the coil in the portions centering midway between the deformations constitutes a cushion for the globe and facilitates the axial rotation of the globe while in position in order to display any particular portion of the globe. The deformed coil braces up a globe and elfects a dust-proof oint at the bottom of an adapted form of holder. The globe is automatically centered on the holder by reason of the symmetrical inner and outer lines of the deformed coil. The deformed coil when in use is concealed from view, thereby preserving the sightliness of the holder and permitting uninterrupted ornamentation on its moulding.

What I regard as new and desire to secure by Letters Patent is 1. A globe-support consisting of a holder having a groove on its inner side, a resilient open cylindrical coil having a plurality of deformations adapted to engage and press against the neck of aglobe and to engage and press against the'inside of the groove in said holder when the said coil is positioned 7 between said neck and said groove. v

2. The combination with a globe, of a globe-holder having a groove therein, of a globe-support consisting of a separable resilient open cylindrical coil having its ends connected together and having a plurality of deformations adapted to engage and press on the neck of said globe and having a plurality of deformations projecting from said neck and adapted to engage and press against the inside of the groove in the holder when said globe is positioned in said holder.
