7 claims. (C1. 24o-51.12)

This invention relates to an electric lamp fixture, with reference more particularly to a structure for supporting a, pair of circular lamps of dilerent diameters one within the other in planes at right angles tc one another or in other angular relationship and it has for its purpose to provide a simple, practical and efficient structure-that is pleasing to the eye and which permits two such lamps to be readily positioned for use or removed easily for replacement.

More particularly the invention has for its purpose to alford a xture comprising a housing with four radial supports, two for each lamp at opposite 'points thereof, and so constructed as to enable readily positioning the conducting wires leading to the lamp sockets within the housing and permitting a simple and quick assembly of the parts.

Another object of the invention is to alford a housing for the purpose described above that which are separably held together to enclose the conducting wires and form the supports for the lamps, two of the supports being provided with yieldable gripping members that assist in holding the sections together and retain the lamps,

the gripping members being movable to permit positioning the lamps or removing them from the fixture.

To these and other ends, the invention consists in the construction and arrangement of parts that will appear clearly from the following Vdescription when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims following the specification.

In the drawings:

. Fig. 1 is a view in front elevation, partially in section, showing a preferred embodiment of the invention as incorporated in a fixture for supporting two circular fluorescent lamps of different diameters in perpendicular planes;

Fig. 2 is a view similar to Fig. 1, somewhat reduced'ln size, of the front section of the housing, the other section with the switch and conducting wires being removed; Fig. 3 is a view in rear elevation looking in the opposite direction of Figs. 1 and2, showing the K rear section of the housing;

Fig. 4 is a top View; Fig. 5 is a view in side elevation;

Fig. 6 is an enlarged detail horizontal sectional view on line 6 6 of Fig. 1;

Fig. l is an enlarged detail horizontal sectional View on line '1 -'i' of Fig. 1, and

Fig. 8 is an enlarged detail horizontal sectional View on line 8-8 of Fig. l.

The invention comprises in general a housing which encloses the conducting wires and comprises two separable parts or sections, each of which sections includes a central portion for connection with the lamp standard from which the conducting wires lead to said central portion and two pairs of oppositely extending radial arms, the arms of each pair beingof diierent length, preferably in alinement, andserving to support a circular uorescent lamp, and the arms of one pair being somewhat shorter than the corresponding arms of the other pair so as to arrange a lamp of smaller diameter within a larger diameter lamp.

Referring more particularly to the drawings in which like reference numerals refer to the same parts throughout the several views, the housing which includes hollow arms for enclosing the conducting wires leading from the lamp standard to the lamps, preferably `comprises one section including a dished and generally circular central portion l, see Fig. 2, with a pair of radial oppositely disposed

arms

2 and 3, and a pair of radial oppositely disposed arms 4 and 5, preferably integral with the central portion I and arranged in planes at Vangles to one another as shown.

The

radial varms

2 and 4 are of hollow crosssection fora purpose that will appear presently, and the arms -2 and 3 which are preferably alined are somewhat longer than the arms 4 and 5 respectively, whereby the arms 4 and 5 may support a circular lamp positioned within a lamp arranged on the

arms

2 and 3, and the arms '2 and ll are longer than the arms 3 and 5 in order to enable positioning two lamps of dilferent diameters one within, the other inperpendicular planes and arranged so that the diametric center of one lampcoincides withthe diametric center of theother lamp at x, as indicated in Fig. 1.

In order to secure the housing on a lamp standard, the Asection just described includes within its central portion a separable attaching plate 6 provided with oppositely disposed integral collars 'l and il whichiit snugly in recesses provided in the central portion I and in corresponding recesses provided in the other section to be described presently and are thus interlocked with the central portion of the housing. The collar 8 is threaded interiorly to engage the lamp standard or post 9 on which it is mounted, while I0 designates a rod adapted to engage a threaded opening in the collar l and to support a lamp shade as usual. In order to secure the housing tightly on the plateV 6, the latter is provided with herein disclosed, and this application is intended to cover such modifications or departures as may come within the purposes of the improvement or the scope of the following claims.

I claim:

1. A xture for a pair of circular lamps of diierent diameterscomprising a housing having two pairs of supports of dilerent lengths which hold the lamps one within the other and enclose the conducting wires, said housing consisting of two separable sections each of which includes a central dished portion and arms extending radially therefrom of hollow cross-section, and fastening means holding the sections together, the arms of two of said supports having curved seats with plug-engaging sockets and the arms of the other supports having spring-actuated yieldable gripping members pivoted on the arms and having curved surfaces engaging the adjacent portions of the lamps and opposite side walls that straddle the arms of said supports and engage the outer surfaces of' said arms.

2. A fixture for a pair of circular lamps of different diameters comprising a housing having two pairs of supports of different lengths which hold the lamps one within the other and enclose the conducting wires, said housing consisting of two separable sections each of which includes a central dished portion and arms extending radially therefrom of hollow cross-section, the upper support of each pair extending a greater distance above than below said central portion, and fastening means holding the sections together, the arms of two of said supports having curved seats with plug-engaging sockets and the arms of the other supports having spring-actuated yieldable gripping members pivoted on the arms and having curved surfaces engaging the adjacent portions of the lamps and opposite side walls that straddle the arms of said supports and engage the outer surfaces of said arms.

3. A fixture for a pair of circular lamps of dinerent diameters comprising a housing having two pairs of supports of different lengths which hold the lamps one within the other and enclose the conducting wires, said housing consisting of two separable sections each of which includes a central dished portion and arms extending radially therefrom of hollow cross-section, a fastening plate arranged in the central portion of the housing and having an interiorly threaded collar attachable to a lamp standard, the collar being interlocked with openings formed in the central portions of the sections, bosses on said plate having threaded openings therein, and fastening screws extending through said central portions of the sections from opposite sides and engaging said threaded openings in the bosses.

4. A xture for a pair of circular lamps of diiferent diameters comprising a housing having two pairs of supports of different lengths which hold the lamps one within the other and enclose the conducting Wires, said housing consisting of two separable sections each of which includes a central dished portion and arms extending radially therefrom of hollow cross-section, a fastening plate arranged in the central portion of the housing and having interiorly threaded collars at top and bottom, said collars being attachable to a shade-supporting post and to a lamp standard respectively, the collars being interlocked with openings formed in the central portions of the sections, bosses on said fastening plate having threaded openings therein, fastening screws extending through said central portions of the sections from opposite sides and engaging said threaded openings in the bosses, and a switch mounted in the central portions of one of said sections.
