Y GLOBE HOLDER nor.

1 Application filed December object to provide a globe. holding device capable of being clamped about or released from the neck of a globe, and which at the same time embodies the feature of simplicity as regards the manner. of effecting the clamping or releasing of the globe, and which eliminates the necessity for clamping screws.

The holder embodying the resent inven tion is in the form of a split 7 and adapted to encircle the neck of a globe, with provision for drawing the ends together and for permitting the ends to spread apart to effect the globe clamping and releasing respectively.

Further the invention resides in the means for drawing together or allowing the expansion of the ends of the band, this means being preferably embodied in one of the devices utilized to support the globe holder and globe.

Still further the invention resides in a globe holder having part or all the characteristics above referred 'to, and addition.- ally shaped so as to afford a degree of adjustability to adapt the holder to globes whose necks are of slightly varying diameters.

The inventionmay be further briefly sum marized as consisting in certain noveldetails of construction, and combinations andarrangements of parts which will be described in the specification and pointed out in the appended claims.

In the accompanying sheet of drawings, Fig. 1 is a side elevation of my improved holder applied to, or in supporting relation to a globe;;Fig. 2 is an enlarged plan view of the holder removed from the globe showing the holder in full lines when it is contracted and its ends clamped as when the holder is supporting the globe, and showing by dotted lines the ends released and the holder somewhat expanded to permitthe release or removal of the globe; Fig. 3 is a fragmentary perspective view showing how LIGHTING FIXTURES.

one of the holder supporting devices may be utilized to hold the ends of the band or holder in globe supporting position; Fig. a

is a similar View showing the ends released or spread; and Fig. 5 is a perspective view showinga lamp equipped with my invention. .7

In the accompanying sheet of drawings, 10 represents the globeof a. lamp fixture,

which giobe may have any suitable design or shapeand is adaptedto envelop a lamp .inthe customary manner, this fixture being particularly a ceiling fixture wherein the lamp is supported from an upperwall or' ceiling somewhat in the manner illustrated in Fig. 5.] The globe hasthe customary re-j duced neck portion'surmounted by a lip or flange, indicated at 10. The globe holder consists of a circular band 11 which may be formed of any suitable material, but pref erably from metal having. some degree of elasticity which will permit the contraction of the band to the position shown by full lines in, Fig. 2, and its expansion, as indi cated by dotted lines in, the same figure.

The band is. provided preferably at equallyspaced points with a plurality of loops 12 with circular outer portions and paral el inner portions,-as'shown in Fig. 2. The number ofthese loops may be varied and will depend upon the number of points at which the holder and globe are to be supported, as by chains, or cords, or links.

In this instance the holder is to besupported at three points, and therefore three such loops are provided. or devices are designed to be attached tothese loops, and as here shown they include endless straps or links 13 which form a permanent part of the holder andpass through The supporting means openings in the inner portions of'the loops P as clearly shown in the different figures, of the drawing. a Y

One of these'loops, designated 12* is split at a point indicated at 12, forming the two ends of the band which are adapted to be drawn together to contract the band and obviously due to the fact that the link is narrow, the ends of the band at the loop 12 are held together or in the position shown in Fig. 2, in which event the band is contracted or in conditionfor supporting the globe. On theother hand, when thelink associated with the split loop 12 is turned from vertical position to horizontal position in'the manner indicated in Fig. 4, the ends of the band, or the parts of the split loop 12 can spring apart so as to allow the band to expand. p

It will be seen therefore, that the locking otthe band in globe supporting position is brought about by one of the links or parts of the holder supporting means, and that when this link is in supporting position it automatically retains or locks the band in its contracted position. It will be seen also, that it is; only necessary to allow the link 13 associated with the split loop 12 'to drop to horizontal position as relieving this link 13 of the weight of the globe that the ends of the holder are automaticallyflre leased-so that the holder can expand.

Additionally another advantage follows from the use oi a holder in the form of a split band having the external loops lQand 12, and this lies in the tact that the loops provide a'certain amount of excess metal to enable the band to enlarge somewhat to permit it to'be used with a globe somewhat larger than the standard size normally intended to be used with the holder, that is to say,should the external diameters of the.

necks oi the globes vary somewhat, or should the bands vary slightly in size, the lnwardly vxtendin )arallel sides of the loops 12 mav,

s l v expand so as to allow the holder to be clamped about a globe. having a relatively large size neck.

The holder and globe may be supported and connected to the lamp in any suitable manner. For'example, in Fig. 5, the globe and globe holder form a part'otf a ceiling lamp designated asa whole by the reference character 14. In this lamp there isa central fixture 15 which contains the lamp proper, the top ofthis fixture being supported from above by supporting members 16 and the links 13 or" the globe holderbeing connected to the upper part ofthe fixture by supporting rods or links 17.

It will be seen therefore, that I have provided globe holder which does not require holding screws, and whichat the same time embodies the features of simplicity and utility to a high degree.

I do not desire to be confined'to the exact details shown, but aim in my claims to cover all modifications which do not involve a de-, parture from the spirit and scope of my invention in its broadest aspects' Having described my invention, 1 claim:

Lit globe holder for a lamp, comprising a split band adapted to be extended about the neck of a globe, said band having portions adapted to be drawn together or spread apart to permit the band to be contracted or expandethand an elongated substantially flat endless link slidably and .rotatably engaging the endportionsot the band whereby when said link is in a positionin which it extends lengthwise alongside the band the band. is free to expand and when. said link is turned to a position at right angles to the plane of the band said band' is contracted and held in contracted position. o

2. A globe holder comprising a split band adapted to encircle the neckoi a globe, a plurality of holder suppoz-ftin'g links connected to said band, and supporting members connected to said links, one said links adjustably engaging the ends of the band adjacent the split and serving to hold said ends relatively close together or to permit them to spread apart, depending upon the position that the llnk assumes with reference to sald band.

3.1L globe holder for a lamp fixture comprising split band having outstanding ends at the point of the split, and a plurality of holder supporting devices connected to the holder, one of said devices eugaging said ends of the band to hold the band contracted, said end engaging support 111,9; device belngmovable wlth respect to comprising a band adapted to encircle the neck of a globe to be held, and provided with" a plurality of outwardly extending loops, one of the loops being divided into two parts forming a split band, and a plurality of holder supporting. links extending through said loops, one of said links serving to hold the two ends or portions of the split or divided loop relatively close together andto permit them to spread apart,

depending upon the position that said link assumes with reference to said loop.

In testimony whereof, I hereunto allix my WILFRID LUMLEY.
