The extension blades 29 are adapted to be secured in a setk position of adjustment with respect to the arms of the bridge by meansof the screws 3 with which the bridge is connected to the outlet boX. The canopy 28 which is of the large s-ize is equipped with a lamp receiving socket 34, the terminal Wires of which are adapted to project upwardly through the opening 14 of the middle section' of the bridge to be connected up with the terminal wires in the outlet box 1. The canopy is provided with openings through which supporting screws 35 project; The upper or inner ends of the supporting screws 35 are adapted to be threaded through the threaded apertures 32 provided in the ends of the extension blades 29. It will thus be noted that the canopiesof different diameters may be readily mounted in position with the upper end of the canopy properly seated against the ceiling or wall 4 as clearly illustrated in Figure 6.

Figures 10 to l2 inclusive illustrate a modified or straight type of fixture bridge which is shown in Figure 10 as being supported on a small size or deep standard outlet'box o6 of the standard 3% inch diameter size. VThe outlet box 36 is provided with inwardly directed fingers or lugs 37 having threaded openings in which supporting screws 38 are adjustably engaged. The modified straight type of xture bridge comprises a straight body plate 39 having a longitudinally positioned center slot 40 provided in one end thereof and a slot 4l in the opposite end. The slot 41 is provided with an enlarged opening at 42 to facilitate mounting of the bridge Aon the screws 38 of the small size standard outlet boX 36. To mount the straight type of bridge on the small standard size outlet box the end of the slot 40 is engaged around the shank portion of one ofthe supporting screws 38'with the opposite end of the bridge positioned beneath the opposite screw after which adjustably positioned with respect to the outlet box. After the bridge has been mounted as illustrated in Figure 10 the screws 38 may be tightened to rigidly hold the straight bridge in a set position of adjustment. The

straight bridge is provided with a middle opening 14, `a pairjof diagonally opposite plain openings 28 and a pair of diagonally opposite threaded openings 29 grouped around the middle opening 14. rlhe straight bridge is also provided with a pair of diagonally opposite threaded apertures 9 and with a pair of diagonally opposite plain openings 10 arranged near the end of the bridge similar to the arrangement of the apertures in the bridge disclosed in Figures 1 to 5 of the drawings. Also provided in the middle portion of the straight bridge 39 isa pair of diagonally opposite openings 43. The apertures 43 are provided for the purpose of'attaching a large sized electric light socket to the straight bridge 39. The longitudinal or side margins Vof the straight bridge plate 39 are deflected or bent over to provide reinforcing or guide fianges 44. The construction of the straight bridge having the various slots and openings therein permits the straight bridge to be readily secured to standard outlet boxes of different sizes.

Figure 13 illustrates a modified form of the straight type of fixture bridge in which the straight bridge is constructed substantially the same as that illustrated in Figure 11 having mounted through the middle opening 14 thereof an insulated bushing 45 which is internally threaded for the reception of an adjustable supporting screw stem. The stem receiving bushing 45 is insulated from the straight bridge plate 39 by a plurality of 'adjacently positioned insulation washers 18,

19 and 2O similar to the insulating members illustrated in Figures and l5. Positioned to the outside of the insulation washer 20 is a metal retaining ring 21 which is held in positionA by means of the swaged or outwardly Vdeflected end of the bushing 45.
