Abstract: A cabinet having an opening in the bottom thereof through which electrical conductors are extendible from a street light base, the cabinet having a cover detachably secured thereto which is lockable in place. The cabinet is secured over the base of the street light which are of various shapes and sizes by bolts extending upwardly from the base through a plurality of clamp bars. The clamp bars are adapted to adjustably fit over the existing bolts of the street light base and extend over a lip formed in the bottom of the cabinet to secure same to the base over the wires. The wires are connected together and a cover is locked in place over the wires to prevent shock from the electrical current.

Abstract: A span trolley detachably connectable to a line suspended between first and second poles to draw an end of a cord from the first pole to the second pole. Two guide wheels and a drive wheel, secured to a chassis, are resiliently urged into engagement with the line extending between the poles. The chassis is moved along the line by a reversible variable speed electric motor to draw a cord having an end connected to the chassis along the line. The resiliently mounted guide wheels are adapted to move transversely relative to the line such that the span trolley passes splices and other obstructions along the line and maintains the drive wheel in driving engagement with the surface of the line while obstructions are being traversed.
