Original application May 5. 1927, Serial No. 1 189,058. Divided and this application September 30, 1929-WS6L'1E1 N0. 396,213

This invention relates to electrical connector socket-devices provided with facilities for supporting in assembly a lamp,f.shade, reflector and .the like and for ready connection with and disconnection from overhead suppOrts -the electrical connection being established by aplugging in action as'between the cooperating parts of the connecter. I

The present application is a division of my May 5, 1927. 3 A

My copending application of even date herewith, Serial No.'396,214 is also a divisional appli cation of my pending application, Serial No.

The invention may be understood by the following description together with the accompanyingdrawing in which:

Figure I is a view in elevation of'a suspende lighting unit with a .connecter-embodying the invention.

Figure II is a plan view of the lamp supporting parts of the connecter ready for installation, the socket being illustrated with a shade-holder fitted therein. Y Y

'Figure III is a fragmentary detail view in side elevation of the connecting partsv shown in Figure I.

- 1 Figure IV is a detail view in elevation on a larger scale of the connecter members shown in Figure I. Figure V is a side elevatio'n'of the bail shown in Figures I, III and IV. 3 Figure VI is a view' in'elevation, partly in section, of the socket member with the parts assembled, with part-of ,a shade holder, and ready to receive the bail and the shade holder.

Figure VII is a modification of the invention wherein the bail engages with the supply wires for 40 'supportingthe fixture, and Figures VIII and IX are details of the bail and clamping means for engaging the supply wires.

r Proceeding now in accordance with theinvention, 'ke reference characters refer to similar parts in the respective figures.

In Figure I, the'complete lighting fixture. is shown in assembled relation, depending by its support from theceiling, wherein 1 is a glass shade supported by holder 2, which depends for 0 its support in'turn by resting, upon the top of socket member 3 which is concealed by the holder in Fig. I but shown in Figures IV and VI. Socket 3 is adapted to receive a lamp threadedly, in a conventional manner, or other device. Socket 3 has blades 4-4 projecting upwardly therefrom *in eyes" 8 which latter are securedto socket 3.

other extremity of the bail into the other eye.

and adapted to be received by corresponding apertures in andfengage with contacts carried by receptacle 5, the contacts of the latter being connected with supply wires 6. A bail 7 engages 4 One ,or bothof the eyes may be rotatably secured to the socket 3, and provided with a cushioning v spring 9 secured onto eye 8 by nut 10. This arrangement permits of the insertion ofjone of the ;eye and allows for a swinging motioof bail 7 into the plane with eyes 8-8 whereupon the extremities of bail may be pressed toward each other, thus permitting ready insertion of the The bail may also be inserted in the eyes 8 be-' fore the latter are secured into position with socket 3. The upper'end of bail '7 may be formed into a-loop or eye as at 11 in Figures I, IV and V, for receiving the hook or open ended link 12 carried by chain or overhead support 13 which depends from the ceiling as at 14, 15a being a canopy with hook for engaging the chain. 15-45 are screws for securing shade 1 and reflector 2 in asseinbled relation. As shown in Figures I, IV and VII, receptacleB ha's'a groove 16 on the surface of receptacle 5 to receive bail 7, the purpose of which is that when blades 4-4 of socket 5 are plugged into receptacle 5, the bail 7 being of proper dimension as at -a-- Fig. V, may be swung upwardly and snapped into grooves 16.

i It will be readily understood that that part of bail '7 depicted at 11, may be formed into a hook for engaging with a' link of a chain or the like for supporting the assembled fixture, and affords means whereby ready engagement and disengagement of the fixture may be had instead of the form as shown.

In the modification as shown in VII, VIII and IX the fixture depends for its support upon engagement with the supply wiresas follows; bail 17 engages with eyes 8 and snaps into engage-' ment with receptacle 5 in the manner previously pointedout and may be formed with a recess as at 1'7 to accommodate the supply. wires. Bail '7 being provided with-a rivet 18 which is received at its opposite end by strap 19, which lattermay be readily moved'into a position parallel with the l upper section of bail ;7 and being provided with 5 an opening to receive the same, is passed over threaded stud 20 which latter is thereupon fitted with wing nut 21 by meansof which the strap 19 isdrawn down on supply wires 6, thus affording frictional engagement therewith by means of which the fixture assembly is 'supported. The

operation is as follows;

Eyes 8 are secured to socket 3, holder 2 is then passed over the socket, blades 4 and eyes 8 projecting through suitable openings in the holder, and a lamp is screwed into the socket. Shade 1 and holder 2 are secured by screws 15 in assembled relation, bail 7 is assembled into eyes 8 and swung away so receptacle 5, which has previously been connected with supply wires 6 depending with chain 13 from the ceiling, may readily be seated upon a socket 3 receiving blades 4, thus establishing the electrical connection with the lamp. Bail 7 is then snapped into grooves 16 and open link or hook 12 receives the bail, thus establishing the mechanical connection for support of the fixture.

To disconnect the socket and its appendages, it remains, only to disengage-bail Tirom link or hook 12, swinging bail l-away fromreceptacle 5 and lowering the fixture which latter movement will of itself disconnect receptacle 5 andsocket 3.

While I have shown receptacle 5 provided with grooves 16 and described bail 7 as of such dimension as to seat therein by snapping engagement, this is but a preferred formof my invention as it will be readily understood that the bail may be entirely free from receptacle 5 and the latter be formed without grooves 16 if desired.

In themodified form, the operation is the sam as that of the form described above, except that the bail, through strap 17, is caused to engage frictionally' with the supply wires and support the.

fixture thereby instead of engaging with a hook or open link of a depending overhead mechanical support independent of the supply wires. It will be further understood that in the modified form shown, a special or strong covering for the supply wires may be utilized whereby to provide for the strength requisite to support readily the weight or the fixture.
