these straps may be; provided-with one or more openings Zen-through which may extend screws or the-like-for thesecurement-of said straps to the upper? surface of the ceiling {panel .23. As here shown, the lower edge of ,the sleeve orband 24 is ciroumferentiallylslotted to provide a series of tongues 2 l"- .Whioh are bent laterally outward above and belov l, and which are solderedor otherwise permanentlysecured to, the inneredge of aring 28;;the sleeye or band 2d: and the'ring 28 being thus made aeunitary; structure. If desired, how ey er the; ring. ,;2 8; may be formed as; anyintegral; part of the sleeve or,band 24, as will be readily understood.

Tdienablethepresent fiiiture to be easilyiand conveniently mounted or installedwithin-the-ceil:

ing; opening 22; the ring-carryi g sleeve orband 24 1s; suitably forrnedfor the detachable oonneo tion thereto oi -the lower: endportion of the bodyl or; housing memberi Ill.

" sleeveonband:Zaisprovided with two or more circu nferentially spaced openings and withj-a threaded nut- 29 111 alignment; with each of said openings, the nuts being soldered or, otherwise. p er rnanentlysecured'to the sleeveor band. The

lowerend portion of the body orhousingmember lu isjprovided with a corresponding set of open! nst, and bath u e s r w a Said ho in or bodyir ernbenmay be detachably connected to the s1eeye-,,or. band;v a will be readily understood.;

For such; purpose, the- In mounting or installing the fixture, as thus far described, in the ceiling opening 22, the sleeve orband 24 is first positioned in said opening, with thestraps 25 extending upwardly in unbent form and with thering 28 carried by said sleeve or band in engagement with the lower surface of theceiling panel 23, as in Fig. 1. Inasmuch as the body or housing member ID is disconnected from the sleeve orband 24 and hence not yet in place, it is a simple matter to reach up through the sleeve orband 24 and bend the upper portions of thestraps 25 down against the upper surface of theceiling panel 23, and to secure said straps, by screws or otherwise, to said panel. The body or housing member Ill, with the lamp bulb IS in place and with the lead wires l4 connected to the socket I8, is then pushed into position within the sleeve orband 24, the lower end portion of said body or housing member being thereafter detachably connected to the sleeve or band by the use of thescrews 30.

To determine the size and shape of the bottom opening of the fixture and to give the fixture a finished and pleasing appearance from below, the fixture also includes a suitable bottom cover plate.

The cover plate here shown comprises a simple sheet metal member having a fiatcentral portion 3| of disc-like form and an upturnedcircumferential fiange 32 adapted to seat inside of (as here) or outside of a dependingcircumferential flange 33 with which thering 23 is provided. Centrally located in the disc-like portion 3| is anopening 34 for the downward passage of light rays emanating from the lamp bulb l9, said opening being of any desired size and of any desired shape, such as round or oval, or rectangular, as here shown. If desired, an upwardly extending duct-forming flange orwall 35 may be provided at the periphery of theopening 34 to confine the light rays passing downwardly through said opening to the desired occluded angle, said flange or wall being here shown as an integral part of the cover plate, although of course, it could be a separate member soldered or otherwise suitably secured to the disc-like portion 3|.

To detachably retain the cover plate in position, anannulus 36 is riveted at 3'! or otherwise suitably secured within and to the body or housing member Ill in spaced relation thereto and just below the lower end of the depending lamp bulb l9, the spacing of theannulus 36 and the housing I!) being effected by the use of suitable spacing elements 31a, Figs. 1 and 4. Extending upwardly through the disc-like portion 3| of the cover plate, with headed ends below and supporting theportion 3|, are two or more threaded rods orbolts 38, there being three such rods or bolts, in circumferentially spaced relationship about the light-transmitting opening 34, in the present embodiment of the invention. Threaded upon the upper ends of the rods orbolts 38 are clips 39 (one on each rod or bolt) havingbent end portions 40 adapted to be hooked over theannulus 36 of the body or housing member [0.

Therefore, after the ring-carrying sleeve orband 24 is secured in position Within the ceiling opening 22, with theceiling panel 23 disposed between thering 28 of said sleeve or band and the downwardly bent upper end portions of thestraps 25, and after the body orhousing member 16 is secured to said sleeve or band by thescrews 30, the bottom cover plate may be easily and conveniently mounted in place, theclips 39 on the upper ends of the rods orbolts 38 being readily hooked over the annulus 3B of the body or housingimember I!) by reaching up through the lighttransmitting opening 34 of the'cover plate.

At any time, when desired, the cover plate may be readily removed, for inspection, replacement or adjustment of the lamp bulb I9, by merely unscrewing the threaded rods orbolts 38 to disconnect theclips 39 from thehousing annulus 36, the exposed headed lower ends of said rods 01' screws being slotted, if desired and as here shown. Similarly, the body or housing member ID may be conveniently removed, after removal of the bottom cover plate, by merely unscrewing thescrews 30 which connect said member with the sleeve orband 24. I uIfdesired, of course, the opening 34 of the bottom cover plate may be provided with a glass or other light transmitting member, of either transparent or translucent character, and of either colored o uncolored nature. Similarly, louvers may be provided for the cover plate opening 34, if that is desired.

To those skilled in the art to which the present invention relates, other features and advantages of lighting fixtures embodying the invention will be evident from the foregoing description of one such embodiment.
