LIGHTING FIXTURE.

Application med June 2e, 1925. serial No. 39,645.

The present invention relates to lighting fixtures and is more particularly directed tolward the provision of an improved lighting fixture of the type shown `in Amiguet Patent No. 1,371,015 dated March 8, 1921.

Itis frequently desirable to-provide lighting fixtures with a convenience outlet and a switch control mounted on the fixture in an accessible position, so that one can control the lights in the fixture and connect electrical appliances to the fixture, and the present invention contemplates the provision of such a fixture having the light distributing and illuminating advantages, of theunit shown in above mentioned patent, with a form ofconstruction by which one can control the lamp and connect in appliances'at will.

An object of the present invention is to 'provide a lighting fixture preferably of the indirect type with an accessible current tap and switch control which is preferably so arranged that it does not interfere with the removal of the refiector and transparent dish.

Another object of the present inventionis to provide an improved yform of lighting fixture, in which the switch for controlling the lamp is carried on the lower side of the lamp and wherein the wires leading to the switch are effectively concealed and protected.

Another object of the invention is to provide a lighting fixture having a current control and outlet tap carried underneath the lamp in such a manner that it does not cause objectionable shadows or disgure the fixture.

Another object of the invention is to provide a fixture construction, which permits permanently wiring the lamp socket, convenience outlet and switch.

Another object of the invention is to provide a lightingfixture of the indirect type in which the supports for the reflector are also utilized as conduits to carry Ithe wires to a. combined switch and convenience outletlsupported at'the lower end of the supports. Other and further objects of the invention will appear as the specification proceeds:

In the accompanying drawings there is shown, for purposes of illustrating the invention, one of the many possible embodiments in which the present invention may take form, it being understood that the drawings are merely illustrative of the invention rather than limiting the same.

Fig. 1 is a sectional view with parts in elevation showing a lighting fixture;

Fig. 2 is an enlarged sectional view of the lower central part of the fixture;

Fig. 3 is a fragmentary detailed view taken on the plane 3-3 of Fig. 2, looking in the direction of the arrows; and

Fig. 4 is a circuit diagram for the fixture.

The loop for supporting the fixture is shown at 10 and is fastened in any suitable manner to a yoke 11 the lower ends 12 of which are attached to a flange 13 of a stamping 14 by riveting or otherwise. vThe lamp socket 15 is mounted on this stampin the usual manner. The rim or flange 13 o the stampin 14 is also provided with regularly spaced oles preferabl three in number, and in each of these holyes there is carried a length of tubing 16 bent to the proper shape to form the major portion of the frameof the fixture. v

Nuts 17 may be used to hold the ieces of tubing in place. These pieces of tu ing extend directly downward from the stam ing 14 and are then bent obliquely outwar as indicated at 18, to pass by the electric lamp 19 carried inthe socket 15. The tubing 16 is then continued down as indicated at 20 to provide a guide for "the opaque deflector 21,'

and these lengths of tubing are then bent at right angles and continued horizontally as.

stamping 25.

This stamping 25 provides a housing for an electrical unit which may be in the form of a combined switch structure and convenience outlet 26. It may be inserted. into the housing from. above with-the lower end 27 of this structure extending out through a hole 28 in the bottom of the housing 25 where it is threaded as indicated so that a nut 29 ma be threaded in place to fasten the switcli structure to the housing. The lower end of the structure is provided with suitable slots of the ordinary construction so that a plug 30 may be cooperatively associated with the same. In order that the electrical unit may be properly aligned in the housing and revented from rotation there is provided a. prong or projection 31 struck up from the flange at the bottom part of the housing and ythreaded holes 24 in a cup shape sheet metal los l arranged to enter a notch or slot 32 inthe insulating body of the switch. This will prevent rotation of the structure and will align the same so that the pull chain 83 will pass back and forth readlly through the guide 34.

The supporting members 16 here shown in the form of tubes are threaded into holes 24 and then attached to the stamping 13. The Wires for supplying and controlling the lamp and convenience outlet may be placed in the fixture as indicated in Fig. 4. One of the leads 35 passes directly down through one ofthe supporting members 16u to the common terminal 36 of the unit AQ6. The other lead 3T is attached to one of the terminals 38 of the lamp socket and is carried down `through another supporting member 16b to the terminal 39. The third supporting member 16c is utilized as a conduit to carry a wire which is connected to the third terminal 40 of the lamp socket and with the remaining terminal 41 of the switch. The switch is indicated at 42 and the convenience outlet at 43, and it will be obvious from this figure that one is'able to control the lamp by turning on and off the switch 42 and that this will have no effect upon the electric appliance connected into the xture by means of the plug 30 which cooperates' with the contacts 43.

The socket structure 15 and the upper parts of the fixture, above described, may be conveniently concealed by means of a stamped shell or hood 44 passed down over the lamp 10. The opaque rellector 21 may be conveniently supported by' means of clips 45 soldered or otherwise fastened to the body at thev proper point.

i transparent or translucent diffusing screen 46, is preferably provided to illuminate the outside of the deflector and direct a diffused li ht downwardly. This screen may be in the lrm of a number' of pieces of glass suitably supported on the upper side of a -spider 47. The inner part of the spider may be in the form of a ring as illustrated at 48 provided with bayonet slots'49 suitably placed to cooperate with lingers 50 struck out from the housing 25.` The spider may be readily removed by lifting it slightly and turning it so that the prong 50 may pass through the bayonet slots. The ring 48 of the spider being large enough to clear the lower parts of the housing 25. These parts are preferably so shaped and located that the housing 25 merges into the central part of the spider so that the construction is not noticeable when observing the fixture in the ordinary manner.

After the screen has been removed, the deliector may be removed by lifting it to bring the hole above the vertical portions 2O of the frame members 16. The deliector may then be tilted, one side being lowered clear of the supporting prong and the deliector being freed from the frame. It will thus be seen that the defiector and screen are removable to permit cleaning, and for replacing lamps.

In assembling the xtnre one may thread the lower ends 22 of the tubular members 18 into the holes in the housiiw and then attach the ring 13 and socket to the upper ends of the tubular members `18. The switch, the socket and the convenience outlet may then be easily wired. After the fixture has been wired a paper disk 51 is passed into the upper part of the housing 25 so as to rest above the top of the switch structure 26 and then a metal disk 52 is inserted in place and fastened down by means of a number of inwardly bent prongs 53.
