Permits Unwinding Patents (Class 242/125.3)
  • Patent number: 8302894
    Abstract: The invention is a restrainer for a spool (10) of thread to prevent the thread (13) from being freely drawn off of the spool (10). It comprises a resilient element (12) that extends around the circumference of the outer surface (14) of the spool (10) so that the thread (13) being drawn from the spool (10) must pass between the outer surface of the spool (10) at the inner surface of the resilient element (12) there by impeding the free removal of the thread (13). The invention prevents excessive thread being jerked from the spool.

  • Patent number: 8235323
    Abstract: A reel for a microphone cable, amplifier cable or other electronic cord or cable has an arbor or hub that divides the reel into an interior space and a winding space. The cable leading end connector cable is retained in the interior space. Turns of the main body of the cable are coiled in the winding space. The rims of the reel side disks have annular retaining beads or ridges that face one another and create a snap connector holder for the trailing end connector. A gap in the retaining beads aligned with the arbor opening permits insertion of the leading end connector. The reel can be available in a range of sizes and can be color-coded. The reel can be constructed of two identical molded reel halves.
