GLOBE HOLDER FOR ILL'UMINATING FIXTURES Application filed. May 16,

a holder forming a part ol the lixlure with improvements whereby a shade may be insorted into the holder and held leinpi'ira r1 by a yielding gripper while the holder beii'ig screwed'or adjusted into final position to cause the gripper to permanently and firmly hold the shade.

This object is or 'riod out by means of a gripping device, orcilerably made in sec-- tions which normally extends somewhat a :ross and within the circular opening; ol the holder into which the shade is to be placed, sothat the gripper will more rer'idily ltlh'l) hold of the neck ol the shade and secure the shade pending the linal adjustment of lhe luilder; and which same'pjripping device will. then perinammlly secure lho shade.

in the aceoi'np'anyin51 drawings,

Figure l is a side elevation ol' my unproved shade holder with a conventional electric light shade held thereby;

l igure 2 an enlarged view in vertical section showing; the position ol the parts when the yielding gripper in normal position and. eidendinp slightly within and across the borders of the opening in 'lhe holder enough to temporarily hold the shade;

Figure 3 a like view showing the parls in their final position after the holder has been scrmved home and the yiehling;- gllpl llil." has been. loreed into the groove or noel: ol. the shade; I

Figure 4 a plan view of lhe holder and the yielding gripper, 'lhe latter in normal position when it extends well within the opening in the holder;

Figure 5 is an inverted plan view of the holder looking at the bottom thereof and showing the gripper extending somewhat within the opening of the holder;

Figure 6 is a detached view of the gripper showing its several sections and the ring on which the sections are strung.

Referring to the drawings, the numeral. 1 indicates an electric light fixture oil? any conventional type. This fixture has a lower extension. indicated at 2, and provided with a screw thread on its outside. The lower margin of this extension is beveled as seen at 3 for a purpose presently to appear.

The numeral 4 indicates the outer shell ol the 1927. Serial No. 191,648.

sheet inelalspun up into any desired design.

This shell has soldered or otherwise fitted within. it a screw threaded annulus 5 having a groove 6 Within which is sprung a wire ring to form a shoulder or stop to prevent the annulus from being entirely SCI'QWQLl oil ol the extension 2 of the fixture. This wire ring-like stop is inserted through the opening 7 withinthe shell of the holder 4 alter annulus has been screwed on 'l'he threaded extension 2 of the fixture.

Thus it will be seen that by rotating the holder 4-, it will be adjusted up or down with reference to the fixture by reasrm of its threaded mounting on the extension 2 of the fixture. l

The holder at its lower end is turned inward or formed with a ledge 8 constituting a space 9 within the holder and between the ledge and the lower ends of the annulus and extension 2. On this lodge is placed the yielding gripper, consisting in the present embodiment oi a plurality, preferably "four, oil coil, springs 10. These springs are strui'lp; on a wire ring 11 over which are bent hooks or clips 12 struck up from or lori'ned with the ledge 8. See Figure 2.. These clips seeuro the wire ring and thereby also secure the $.p1' ngs forming the gripper, yet permitt ng the springs to have freedom of 1110K)- inent radially as well as longitudinally. The

natural temflency oi the spring sections is lo distend, in doing which their inner portions make. a short cut across the opening within the lodge 8, and thus project themselves into the space within the inner ina gin of the ledge 8. This is clearly shoim in Figures and 5. I i This extension of the spring gripper sections within the opening in the ledge enables them/to make immediate contact with the shade when the latter is inserted in said opening, see Figure 2, where it will be seen that the head 18 on the neck of the Shade 141- has been snapped or pushed past the grippersections and they have sprung back partly into the groove beneath the bead and are ready to be forced finally further inward into pressing contact with the shade within the groove. See F igure 3. I

In this latter figure, the parts are shown with the holder l screwed upward on the extension 2 of the fixture, so as to cause the bevel 3 on the fixture to force the spring gripper inward and into the groove 15 of the neck of the globe. In this way the shade has become permanently and strongly attached to the holder where it will remain in any situation in which the fixture is used, such as on railway cars. f

it will be seen from the foregoing that this invention provides for the easy and ready insertion of the shade into the holder and of the holding ofthe shade by the au tomatic snapping of the spring sections of the gripper far enough under the bead of the shade to maint the shade safely in place in o I 1 l 1 pending the screwing or the holder upward g on the fixture as above described. i the shade is perfectly safe tronr'talling after it snapped into the holder, the person maliing the attachment is free to remove his hand from the shade and to use the same hand torserewing up the holder. Again, when the shade is to be removed, the person can first screw downward the'holder without tear of the shade dropping. Then he can take hold of the shade with'the same hand he has just used in screwing down the holder and readily withdraw the shade.

It is further to be observed that the gripper herein set forth is adapted for use Y ith difi'erent sized holders, so that the grippers can be manufactured and applied to VHUOHS' f manufactured and utilized tom-ere oil the manuiacturer sizes of hol by dii'ler'L ot the L pcr.

Thus the advantages and features of utility of this improved, shade holder are mani-- fest.

It will be understood that I desire to com prehend within my invention such modihcations as may be necessary to adapt it to Varying conditions and uses.

Having thus itully. described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a shade holder, the combination with a holder proper having its'lower end formed into a ledge having clips,cfa grippercomposed of a 'alurality of helical spring sections adapted torest on the ledge and to proeet t ieinselves inward from the margins of the opening within the ledge, and a retaining device for the spring sections in the nature of a wire ring and clips adapted to enand loosely hold the spring sections.

2. In a shade holder, the combination with a fixture having a threaded extension, a holder proper having an interior thread adapted to be screwed upon the extension and having also a l dge at its lower end with a large opening within the ledge for the insertion oi a shade, and a spring gripper composed of a plurality of sections made each of a helical spring, the springs being adapted to normally position themselves within said opening, and means on the ledge engaging the spring to loosely retain them in position, the interior of the holder proper being adapt-ed when screwed upward on the fixture to force the spring sections further into the opening and to sent them in the groove of the neck of the, shade.

3. In shade holder, the combination with a fixture and a holder proper screwed thereon, of a spr ng gripper made in sections and loosely mounted within the holder and adapted normally to extend somewhat within the opening in the bottom of the holder, whereby a shade may be inserted past and be temporarily held by the spring sections to hold the shade while the holder proper is being screwed up on the extension, an inner portion of the holder being adapted to then force the spring sections permanently into the neck of the shade, and means on the holder for positively holdingthe gripper, in position in the holder.

4. In a shade holder, the combination with a holder having lower end formed into a edge, a grip member composed of a pluality of helical spring sections adapted to on the ledge and to project inwardly pm the margin of the openings formed by
