lt is a further purposevof my invention to l5 provide fixture hanger capable of use in supporting fixtures having bases or canopies of iarious styles and sizes so that the hanger rendered capable of universal application eliminates the necessity of providing ny different forms of hangers to accommodate the many different varieties of fixture canopies and bases.

l will describe only one form of fixture hanger embodying my invention and will thenpoint out the novel features thereof in claims.

In the accompanying drawing Fig. 1 a vertical sectional view showing 9 one form of fixture hanger embodying my U0 invention applied to an outlet box and to a fixture of the wall type;

2 is a plan View of the hanger;

Fig. 3 is a sectional View of the hanger taken the line 3-3 of Fig. 2; and d Fig. 4 is a fragmentary sectional view of ii portion of the hanger with a conventional adapter nipple of the character employed to secure certain types of fixtures to the hanger.

Referring specifically to the drawing in wliicl'l simil sii liar parts in each of the several views, my invention in its present embodiment is preferably constructed of sheet metal of suitable c to provide a body portion B adapted to secured to an outlet box O, and other poriens and B2 to which the base or canopy (l of a lixture F is adapted to be secured. body portion B in the present instance cemprises an annulus 10, while the portions reference characters designate B and B2 are in the form of arms 11 and'12 respectively, projecting radially outward from the annulus at diametrically opposed points. The annulus is provided with slots 13 through ywhich fastening members are adapted to be extended, and in the present instance three slots are shown and are of arcuate contour and arranged in a'single circular series concentric with the annulus. Spanning the annulus diametrically is a web 14 having a threaded opening 15 therein and axially disposedr with respect to the annulus.

' The opening 15 is adapted to threadedly receive a length of tubingk (not shown) or an adapter nipple 16 (Fig. 4) in securing certain styles of fixtures to the hanger. The openings 14a formed in the annulusat opposite sides of the web 14 provide for the passage of current conductors from the outlet box to the fixture supported by the hanger. f Each of t-he arms 11 and 12 is provided at predetermined spaced intervals along its length with a series of threaded openings 17, any of which are adapted to receive fastening members for securing the base or canopy of a fixture to the (hanger. Intermediate the openings '17 the arms are preferably scored transversely as indicated lat 18 to facilitate breaking off of more or less portions of the arms to `vary the overall length of the hanger and thus render the latter capable of being received in bases or canopies of different dimensions in plan.

In the use of the hanger above described, it is secured to the outlet box O by headed screws 19 which are first extended through the slots 13 and then threaded -into lugsr 20 formed on. a. conventional plaster .ring 21 with which the outlet box shown is provided. Before the screws 19 are tightened, the hanger is adjusted circumferentially relative to the outlet box by rotating the hanger bodily upon the screws 19 untila the position of the arms 11 and 12 is such that when the canopy or base C of the fixture is secured to the arms, the fixture will be properly positioned on the wall with respect tothe perpendicular, or in the case of a ceiling fixture its contour or surface ornamentation displayed to the best advantage or at the most desirable angle.

.outlet box.

Screws 22 are new passed through openc ings provided in the base or canopy of the fixture, and are threaded into the particular openings 17 of the arms 11 and 12 which register with the screw receiving openings of the base or canopy, it being understood that the spacing of the latter openings is standard for all fixtures having bases oir-canopies of a particular size, and thatV the distances between the openings 17 of one arm 11 and the corresponding openings in the other arm `12 are in agreementwithv thespacings ofthe screw receiving openings of the various sizes of standard fixture canopies and bases.

In the event that the fixturetobe hun@ is provided with a canopy or base other than the largest standard size, the required amount necessary toreducethe overall length of the hanger to a .lengt-li which will'beV received in the canopy or base as shownin Figi, is removed from the arms 11 and 12 by breaking off portions of the latter atthe proper score lines 18 prior to. securing' the hanger to the It will be manifest that by the provision ofthe arcuateslots 13 in the annuliis 10., sufficient circumferentialV adjustment of the hanger can be effected to correctly position the fixture irrespective of the position of the .lugs 20 konftlie plaster ring. 21 ofthe outlet box, and that by the simple expedient of re moving' the proper portions of thearms 11 4and' 12 the'hanger is f rendered adaptableto canopies and bases of different standardsizes. Furthermore, by the provision ofthe web 14 withitsthreaded openiiig.15,.the hanger can be employed tofsecure a 'fixture to an outlet box, in the event that the fixture is of the type in which its base is provided with ya single Acentrallydisposed screw receiving opening rather than two openings adjacent its marginal edge as is Athe particular type. of fixture illustrated; In thiscase a short length of'tubing (not shown) is threaded intol the openingsl, and is of sufficient length` to ex- Y tend through'the screw .receiving opening of the fixture base to receivea nut (not shown) `for clamping the fixture base to the hanger,

Y ItY will benoted'tliat the web 14 is provided with a pair of threaded openings 23adapted to receive fastening members forsecuring` to 'the hanger a cleat receptacle (not shown) which is employed in conjunction vwith certain types of fixturecanopies and bases.

Although I havefherein shownand described only one form of `fixture hanger embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims. Y
