This invention relates to certain new and useful improvements in lighting fifiures and refers more particularly to means for attaching the glassware of street lighting fixtures.

In certain types of lighting fixtures the re fractor or lightdifiusing means is enclosed in a glass bowl or globe which is detachably connected with the hood or body portion of the fixture. Heretofore the construction of the connecting meansor glasswareholders, made attachment 1 and removal'of the glassware an arduous task requiring consid-y erable strength and, it is, therefore, an object of this invention to simplify the construction of glassware holders of this type to materially facilitate the attachment and removal of the glassware.

Another object of this inventionis to pro videmeans for attaching a glassware holder with its support, which embodiesthe principle of the ordinary re-closable bottle stopper. With the above and other ob-jectsinview which will appear as the description pro ceeds, our invention resides in the novel construction, combmation and arrangement of.

parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the preciseembodiment of the hereindisclosed invention may be made as come within the scopeof the claims.

In the accompanying drawings, we have illustrated two complete examples of the physical embodiment of our invention con- I Figure 2 is an enlargeddetail 'Vslightly modified construction. 5G

Figure 3 is a fragmentary perspective view of the glassware holder illustrating its means of attachment to the fixture carried support, and r I 1 Figure 4 is a view similar to Figure 2 of a Referring now more particularly to the accompanying, drawings, thenumeral 5 represents the body of a conventional street lightingfixture having a socketfi for the receptionof a lamp 7. Secured-tothe bottom ofthe'bo'dyb risrahood 8 from whichan annularflange 9" extends downwardly. .The annular fiangeQhas a-refractorring 10 con nected therew th by having oneside hingedly connected to a. portion oftheihood, as at 11, and its opposite side provided with a de-' ary, the refractor ring 10supportsa refractor globe 13 which encloses 't-helamp 7 1:0

difiuse the lightin anydesired manner;

Enclosing the refractor bowl-13 is a glass bowl, 14 of any suitable design or configuramounted by havingtheirjends riveted to the band, as at 20, the medial portions ofthe segmental springme'mbers 19-arespaced from the band and have U-shaped brackets 21 rivcted thereto, as at 22'. Attaching bails indicated generally by the numeral 23, are mount- 'tachable securing'means .12; As is customed between thearms of the brackets 21 to provide means for readily detachably connecting theband or holder 16 lugs or projections Qexjtendihg outwardly from theadjacent peripheral edge of an annular flange forming part of the refractor ring 10. p .Thebails 23are of the type commonly employed in reclosing bottle stoppers and consists oftwo sections 26' and 27. Both the secin I tions are preferably formed of wirev and the section 26 :issubstantially U-shaped and has itsoutermost ends 28 directed laterally to be received in loops 29 formed in the medial portions of thearms ofthe section'27 which is I also U-shaped. The sections 26 and 27 are thus pivotallyconnected by the reception of the ends 29 in the loop'sf28 and the outer ends the ends ofthe U-shaped brackets 21, as at 30. 9

of the section 27 are pivotally connected with To secure the bowl 14 over the refractor, the closed ends of the bail sections 26 are engaged over the lugs or projections 24, as clearly illustrated in Figuresl and 2, and the closed end of the section 27 is forced downwardly. This action, as will be readily apparent, forces the spring members 19 upwardly to securely hold the peripheral edge of the bowl against the underside of the annular flange formed on the refractor ring which, to prevent in ury to the bowl, is preferably provided with a cushioning ring 31. Continued movement of the closed end of the bail section 27 causes the axis of the pivotal connection between the sections to pass inwardly of an imaginary line drawn through the pivotal connections 30 and the outer ends of the projections orlugs 2a with which the closed ends of the bail sections 26 are connected, whereupon the parts will be maintained in operative position until the bail section 27 is forcibly moved outwardly,

The engagement of the ciosed' end of the bail section 27 with the adjacent surface of the glass bowl serves to limit inward movement thereof. In this; manner the attachment and removal of'the glassware from its fixture carried mounting means is greatly facilitated and if desired the closed end of the bail section 26 at one side of the bowl may be non-detachably connected with its lugor projection 24, as at 32, in Figurefl. i I

With this construction the glassware holder is hingedly connected. with the refractor ring so that dropping of the glassware upon detachment thereof to permit access to the interior of the fixture is prevented.

What we claim as our invention is:

1. A supporting device for glassware and the like comprising a support, a member rigidly connected with the glassware, a resilient strip attached to said member at its ends and projecting radially therebeyond, a bracket attached to said strip, a hook engageable over the support, and means connected with the bracket and the hook for readily applying tension to said hook. 2. The combination of a lighting fixture and its glassware, of a supporting device for the glassware com rising a support carried b the fixture, a and connected with the g assware, a resilient strip connected to said band at the ends of said band, and projecting radially therebeyond, a bracket attached to said resilient strip, a member engageable with the support, and a member pivotally connected with the bracket and the support engaging member for drawing the glassware towards the, support, said member moving beyond dead center to readily detachably secure the same in operative position.

In testimony whereof we have hereunto affixed our signatures.
