A drum with a cylindrical body having an upper end and a lower end and a circular bottom wall secured across said lower end includes a cylindrical core having an inner cylindrical surface, an upper end and a lower end which is fixedly secured to the bottom wall to define an annular wire receiving space between said core and said body of said drum wherein an improved wire biasing mechanism is provided for applying a downward force against wire in the wire receiving space, by a generally flat pressure ring resting on the wire and an elongated, elastic element connected to a loop element attached to the lower end of said core for pulling the pressure ring downwardly.

[ Having thus defined the invention, the following is claimed:] [1.] In a drum assembly for transporting a coil of loosely wound wire, said assembly comprising a drum with a cylindrical body having an upper end and a lower end and a circular bottom wall secured across said lower end; a cylindrical core having an inner cylindrical surface, an upper end and a lower end which is fixedly secured to said bottom wall to define an annular wire receiving space between said core and said body of said drum; and, a wire biasing mechanism for applying a downward force against wire in said wire receiving space, said biasing mechanism including a generally flat ring resting on said wire with an internal periphery larger than said core and an outer periphery smaller than said body and means for biasing said ring downwardly against said wire in said space wherein said biasing means includes vertically extending slots in the upper end of said core, a rod-like member extending through said slots and above said ring and an elongated, elastic element connected to said rod-like member and releasably attached to a loop element at the lower end of said core for pulling said rod-like member and said ring downwardly, the improvement comprising: said loop element being a flexible ribbon having first and second ends and a bight portion and means for fixedly attaching said ends of said ribbon to the core adjacent said lower end. [18.] In a drum assembly for transporting a coil of loosely wound wire, said assembly comprising a drum with a cylindrical body having an upper end and a lower end and a circular bottom wall secured across said loser end; a cylindrical core having an inner cylindrical surface, an upper end and a lower end which is fixedly secured to said bottom wall to define an annular wire receiving space between said core and said body of said drum; and, a wire biasing mechanism for applying a downward force against wire in said wire receiving space, said biasing mechanism including a generally flat ring resting on said wire with an internal periphery larger than said core and an outer periphery smaller than said body and means for biasing said ring downwardly against said wire in said space wherein said biasing means includes vertically extending slots in the upper end of said core, a rod-like member extending through said slots and above said ring and an elongated, elastic element connected to said rod-like member and releasably attached to a loop element at the lower end of said core for pulling said rod-like member and said ring downwardly, the improvement comprising: said loop element being a flexible cord having first and second ends and a bight portion, two holes in said core adjacent said lower end and each said ends of said cord being extended through one of said holes and tied with a knot to prevent said ends from pulling into said cord. The improvement as defined in claim 18 including a reinforcing plate glued to said bottom wall and with a center opening surrounding said lower end of said core and glue in said center opening for locking said plate to lower end of said core.
