Application led May 29, 1912. Serial No. 700,377.

To all whom it may-concern:

Be it known that l, JAMES SToDDARna citizen of the United States, residing at Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Shade-Holders, of which the following is a full, clear, and exact description. Y

My invention relates to shade holders, and is particularly concerned with a device of this character adapted to support shadesV in the form of glass globes in which there is but a single opening.

The o bj ect of the-invention is to eliminate the unsightly set screws ordinarily employed to engage a ange surrounding the opening of the globe to attach the same to the fixture.

A further object is to so support the globe that the supporting means do not clamp or hold the globe so rigidly as to interfere with free expansion and contraction of the globe under varying temperatures.

A further object is to provide a holder which renders unnecessary any attaching liange surrounding the opening of the globe.

The particular advantage of this inven' tion is that it provides means for so holding the globe as to obviate the possibility of breakage through screwing up the set screws ordinarily employed too tightly, or through loosening of said set screws by jarring of the fixture to which the globe is attached.

With these and other objects in view as will appear from the following descriptlon, the invention consists in the construction and arrangement of parts, l.a preferred embodiment of which is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of a globe holder embodying my invention, showing how the same is applied to the globe. Fig. 2 is a partial elevation and section of the holder, showing the interior clamping means, in clamping position. Fig. 3 is a view similar to Fig. 2, showing the holder with the holdingarms in position to be inserted within the opening of the globe. Fig. 4 is a detall of the fastening or adjusting nut for the holding arms.

In the embodiment of my invention herein selected for illustration, the holder comprises an outside shell 1, which may be at tached to the fixture in any desired manner, as through an opening 21 This shell may be of any desired diameter, according to the size of the globe and diameter of the opening within which the holder is to be mounted. The edge of this shell is. adapted to engage the globe 3 adjacent the opening therein 4. Within the shell are mounted a plurality of clamping arms 5. The number of these arms may be varied toaccord with the size of the globe to be held, but it is found that four are ordinarily .suiicient for any holder up to and including eight inches in diameter. These clamping arms may be hinged, as at 6, to the shell 1, or may be simply spring arms having one end attached to the inner side of the shell, as by screws or rivets 7. These arms have an offset bend 8 and a globe engaging extension 9, and the arms are of such length that when adjusted to holding position, as indicated in Fig. 2, they engage the inner side of the globe well within the edge of the opening therein. Each arm has xed' thereto a screw stud 10 to receive a threaded sleeve or nut 11 eX- tending through an opening 12 in the shell l, the outer end of said sleeve being provided with an operating head 13, which is preferably -knurled to facilitate the operation thereof.-

. When the globe is to beattached to the holder, the clamping screws and nuts are extended to their full length, as indicated in Fig. 3, whereby the outer ends 9 of the clamping arms are collapsed so as to be easily slipped within the opening of the globe. The ends 11 are then screwed up until the arms take the position indicated in Fig. 2, wherein they bear against the innerx side of the globe and hold the same more or less snugly in contact with the outer edge ofthe shell 1. It is to be understood, how-- ever, that to securely hold the globe it ia not necessary to screw up the ends so tightlyl as to draw the globe tightly against the edge of the shell, for the reason that the length of the clamping arms causes them to project well beyond the edge of said shell and well within the edge of the globe when in opera tive position, whereby the globe is, in effect. simply suspended upon the clamping arms. and held in proper relative position by theI edge of the shell. Inasmuch as the clamping ends pass loosely through the openings l/ of the shell, the heads of the same lie doui close to the outer surface of the shell, am when said shell is of the form here indicated Patented Sept. 24,1912. I

that is to say, if the upper surface is retreating rapidly toward the center, these ends will be, in effect, entirely concealed trom view by the shell andby the globe. lt Will be noticed also that the openings in the shell Jfor these ends and the point of attachment of the screws l() to the arms, are so relatively arranged that the headsl oi' the ends willv lie flat against the upper surface of the shell when the globe is attached. The shell may be providedwith Ventilating openings' la, covered, it desired, by ornamental hoods l5.

While l have herein described a particular embodiment of my invention, it is to be understood that the same may be altered in details and relative arrangement ot parts Within the scope of the appended claims.

lll/'hat l claim is:

l. A shade holder comprising a supporting member adapted to engage the outer surface oli the shade and having a plurality of shade holding arms adapted to engagefthe inner surface of the shade, and cooperating means carried by said member and holding arms for collapsing said arms to introduce them Within the shade and for expanding them to holding position wit-hin the shade.

2. i shade holder comprising a shell or trame adapted to engage the outer surface of the shade and having a plurality oit adinstable shade holding arms attached to its inner side adapted to engage the inner surface of the shade, and cooperating means carried by said shell and holding arms tor adjusting said holding arms to position them for insertion Within the shade and for drawing them to holding position against the inner surface of the shade.

3. le shade holder ior shades having a single opening, comprising a hollow shell having an edge adapted to engage the outer surface ot the shade adjacent said opening and having a plurality of adjustable shade supporting arms attached to its inner surface adapted to extend beyond the edge of said shell when said arms are in operative position, and coperating ineens carried by said insee/e shellrand supporting arms for adjusting said arms to engage the inner surface of the shade to support said shade in engagement with the edge of said shell.

Ll. A shade holder :tor shades having a single opening, comprising a member adapted to engage the outer surface of the shade adjacent said opening and a pluralityo adjustable arms attached to said member and adapted -to engage the inner surface ot' the shade adjacent said opening and coperating means carried by said member and by said arms operable to adjust saidvarms to and -lfrorn shade holding position.

t shade holder for shadeshaving a single opening, comprising a member adapted to engage the outer suril'ace of the shade adjacent said openingand having a plurality ol" shade supporting arms adapted to engage the inner surface of the shade adjacent said opening and at points beyond the points olf engagement or said shade by said member, and cooperating screw and nut means carried by said member andisupporting arms tor collapsing said supporting arms to adapt the same tor insertion Within said opening and for drawing said arms into engagement with the inner surface oil said shade to support the same in contact with said member.

6. A shade holder for shader` having a single opening, comprising a Amember adapted to engage the outer surf ice ot the shade adjacent said openii j, a p.uiaiity oi adjustable shade supporting members attached to said lirst mentioned member and adapted to engage the inner surface oli the shade adjacent said. opening, and a screvs7 and nut adapted to operate through openings in said lirst mentionedinember to draw said supporting members to supporting posi- 'tion Within said shade.
