In lighting fixtures, a knOwu-shade-holdlamp-support. A-tubulature" provides a ring arrangement involves loose members passage-way for the conductors or wires which are swung inby a ring telescoping leading to'thelamp, and such tubulature into position. While having many advanmay be extended asa'tubeto a point'of c'om tages, such construction is subject to the ocnection in an outletbox, or simply may te'rcasional loss of one of the'loosefishade-holdminate' in an eyelet 6, for chain suspension ing members." Again, in some locations'the orthe like. TheshelliS has a'terminal portelescoping ring can be jarred back such as ti'on. 7 of cylindrical form, and 1 mounted to allow'the shade-hold ng membersto J all therein is aseries of shade-holding fingers accordance with'vthe present invention how'- Such fingers may' comprise. for -instance,"an'r ever,it now becomes possible to realize the angularly bent metal strip having one end' 1 advantagesofa simple construction" and at in-turnedas at 8,'-t'o engage over the flange the same time avoid loss ofparts, and fur 9 oj-a shade 10, The latter iso'rdinarily of 1'5 therinore, lock the shade-holding members closed globe-form, The other end 11 0f the 65 against accidental releasing.

In order to prevent the the various ways in which the principle of shade-engaging fingersfrom falling out of the invention may be employed. pos'itionin the mounting slot 12, a blister. or In said annexed drawing:r indentation 15 is provided at each side,;these Fig. ,1 is an axial sectional view through being of-suflicient size to prevent slipping a fixture in accordance with theinvention; through-the slot, although inn Wi e hinder: Fig. 2 is a fragmentary section substantialing theiree til ing movements-referredtof--i ly in the same plane, on enlarged scale, For 1 actuating the shade-holding fingers showing the mounting of a shade-holding in common, an actuating ring'lfi is arranged finger and itsrelation to the actuating ring; axially-slidable over the shell portions 7 Fig. 3 is an enlarged perspective view of a normally seating within the rim 17. The

side elevational view of a portion of the in-turned'fiange18 which coacts with astop shell, adapted to receive a shade-holding'fin-- ledge or shoulder'19 on *theskirt-portion of ger; Fig. 5- is a sectional view of the'same, the shell. From this, it will be seen that taken on a plane substantially indicated by the ring 16 may he slid back fromthe skirt- 0 tional view taken on a plane substantially fingers F and allowingnthemto swing out indicated byline V'IVI, Fig; 1. through the-openingsl i so that the flange 9 Referring more particularly to the draw of the shade 10 can be removed from-the ing, there :is shown a lamp-support 2, which shell Conversely; the ring 16 is; slidable 5 I screw-threaded barrel 3 .to receive a lamp and in such movement forcing the fingers bulb base. Coveringthe lamp support 2 is F"into.ishadesholdingfposition against the I a shell S,'secured to thelamp-support by any flange-x9 of, the shade. hen so seated, the; suitable means, preferably screws 4 which ring or band 16 is indistinguishable from the h e g ge nto theuinsu ating po tion of the shellpor tion which itseat on,-

In order to lock the band or ring 16 against undesired movement, looking or holding means is provided, and this may take the form of projections or blisters 20, at one or two, or more points on the periphery of the skirt-portion of the shell S. Corresponding to the placement position of such projections 20, the band or ring 16 has a similar number of notches. When the notches 21' are in alignment with the projections 20, the band or ring 16 may be axially moved with respect to the skirt-portion of the shell, and can be raised entirely free therefrom. When the ring 16 has been seated into its finger-retaining position, a rotational movement of the ring through a short are moves the notch 21 out from under alignment with the projection 20 and places the flange 18 thereunder, and axial move ment of the ring is then prevented.

As will be readily understood from the foregoing, when it is desired to place a shade in position, the ring 16 is rotated, if necessary, such that the notches 21 are in alignment with the projections 20, and by an axial movement of the ring with respect to the shell S, the fingers F are released, allowing them to swing outwardly into the position shown in full lines in Fig. 2. The shade 10 may then be inserted with its flange 9 extending internally of the finger-portions 8. On now axially returning the ring 16 to seating position in the rim 17 the fingers F are all swung inwardly to locking position under the flange 9. A rotational movement of the ring 16 through a short are now disaligns the notches 21 with respect to the projections 20 and the ring is securely locked, and correspondingly holds the fingers F. It is thus seen that placement or removal of the shade is a simple matter, being quickly accomplished, and with the shade in position and the locking ring seated, shaking or vibration may occur without dangerof the shade-holding fingers accidentally releasing. By reason also of the construction of the shade-holding fingers, disengagement or misplacement thereof is impossible.

Other modes of applying the principle of the invention may be employed, change being made as regards the details-described, pro vided the means stated in any of the following claims, or thenequivalent of such, be employed. v

I therefore particularly point out and distinctly claim as my invention 1. A lighting fixture, comprising a lampsupport, a shell thereabout having a cy1indricalskirt-portion, angularly bent shadeholding fingers swingably mounted in slots in said shell and having iii-turned portions operable through such skirt-portion to engage under the outside of the flange of a shade, lugs on said shade-holding fingers at each side of the slots,

and a circular band telescopingly slideable over such skirt-pop tion to actuate the shade-engaging fingers.

2. A lighting fixture, comprising a lampsupport, a shell thereabout having a cylindrical skirt-portion, angularly bent shadeholding fingers swingably mounted in slots in said shell and having inwardly-curled ends exposed through the openings in the skirt-portion to engage under the outside of the flange of a shade, lugs pressed up on said shade-holding fingers at the inside and the outside of the slots, a circular band telescopingly slideable over'such skirt-por tion to actuate the shade-engaging fingers, and means for locating said band.

3. A lighting fixture, comprising a lamp support, a shell thereabout having a cylindrical skirt-portion, angularly bent shadeholding fingers swingably mounted in slots in such skirt-portion, lugs on said shadeholding fingers at each side of the slots, a circular band telescopingly slideable to actuate said fingers and having an in-turned flange, notches at spaced points in said flange, and projections on said skirt-portion adapted to register with said notches when in aligned position and lock against the flange when the band is rotated out of alignposition.
