Abstract: A connection assembly for joining a pair of electric light rail members, wherein a flexible cable mantle extends between and is attached to a pair of coupling members, with each of the coupling members being attached to a confronting rail member. A plurality of similarly shaped fin members are spaced along the mantle, with each fin member extending substantially radially from the cable mantle and each fin member having an outer contour similar to the outer contour of each of the rail members to provide an optically continuous connection assembly.

Abstract: A supporting rail for supporting electrical fixtures or the like. The device comprises an extruded plastic elongate member which is formed at least in part by spaced inner and outer walls that are joined at spaced locations about the cross-sectional periphery of the member. The spaced walls define therebetween longitudinally extending hollow channels for carrying wires or the like, and the inner wall encloses an elongate inner chamber which is open along its length. A structurally rigid rail is thus provided but without requiring the use of substantially solid construction in the extruded rail.

Abstract: A swivel-and-tilt type support fixture for an electric lamp. An elongate tubular conduit member, rigidly supported on an electrical junction box, has an L-shaped member whose one leg is rotatably supported thereon at one end. A friction joint is provided between the L-shaped member and the conduit member so that the L-shaped member can be rotated or swiveled to a predetermined position about the axis of the conduit member. A third member is supported for rotation relative to the other leg of the L-shaped member so that said third member rotates or tilts about an axis which is at a right angle to the axis of the conduit member. The lamp and an associated hood therefor are detachably connected to the third member.

Abstract: A plug receptacle for receiving an adaptor designed for insertion into an electrical contact rail comprises a metallic base plate having a pair of metallic arms affixed thereto and extending in spaced facing relation to one another outwardly of said plate. A central insulator member is attached to the base plate between the arms, extends from the base plate toward the spaced free ends of the arms, and cooperates with the portions of the arms outward of the free end of the insulator to define recesses which are complementary in shape and dimension to the opposed supporting clips of the adaptor. The insulator member includes a central opening in alignment with the space between the free ends of the arm, and supports a pair of electrical conductors which face said central opening and which are positioned for engagement by opposed electrical contacts of the adaptor when the adaptor is inserted between the free ends of the arms and rotated to turn the adaptor supporting clips into the recesses.

Abstract: An adaptor, for insertion into a power distribution rail to feed current to the rail, comprises a housing which is shaped and dimensioned to permit the adaptor to be inserted into the open bottom of the rail in a predetermined orientation relative to the rail and thereafter to be rotated through a limited angle between laterally spaced facing edges of opposing webs in the rail to turn supporting clips extending from the adaptor into support channels in the rail and to effect electrical contact between the adaptor and conductors carried by the rail. The adaptor housing comprises a pair of diametrically opposed cylindrical quadrants spaced from one another by a diametrical distance less than the distance between the laterally spaced facing edges of the rail web.
