Patent number: 8336801Abstract: An anti-rotation system that prevents undesired rotation of an outer flange of a strap dispenser includes an anti-rotation element mounted to a shaft of the dispenser and the outer flange mounted to the anti-rotation element. The anti-rotation element and the outer flange have complementary mating surfaces such that when the shaft, on which the coil rotates, ceases rotation, the anti-rotation element, engaged with the outer flange, ceases rotation of the outer flange; thus, inertia of the coil cannot force the outer flange to rotate undesireably. A locking element abuts the outer flange to secure the flange to the anti-rotation element and a pin extends out from the shaft and inserts into a helical track in the locking element so that the pin rides in the helical track. The anti-rotation element also includes a through-bore for a fastener to secure the anti-rotation element to the shaft.Type: GrantFiled: May 12, 2010Date of Patent: December 25, 2012Assignee: Illinois Tool Works Inc.Inventors: Allan J. Bobren, Dustin D. Elliott

Patent number: 7121501Abstract: A wire spooling system for spooling and dispensing wire. The wire spooling system includes a first spool member, having a tubular member with a locking cap and first collar, and a second spool member, having an engagement aperture and second collar. The tubular member extends through the first spool member substantially transverse to the first spool member. The locking cap is positioned at the end of the tubular member opposite the first spool member. The first collar protrudes from the first spool member in the same plane and direction as the tubular member. The second collar protrudes from the second spool member and fits within the first collar. The spool members thereby form a spool shape. Upon fitting the second collar within the first collar, the engagement aperture receives the locking cap of the tubular member, securing the first spool member and second spool member in a locked position.Type: GrantFiled: November 9, 2004Date of Patent: October 17, 2006Inventor: Frederick L. Lea

Patent number: 6902130Abstract: A multiple purpose storage device for Christmas string of lights constructed of plastic molding. Device has two identical octagon shaped sides which twist snap together at a 90 degree angle to form a single component. A single unit molded handle with a non-restricted rotating lever snaps over a boss at each side of the reel just outside the center of the cylinder. A flexible tab facility is molded into the inner side of the reel to hold one end of a string of lights to wrap evenly around the cylinder by rotating a lever. The handle has a storage compartment at the top made with a living hinge for secure closure and easy opening. Device is assembled prior to shipping and is shipped in a sturdy corrugated cardboard box designed for storing reel and for handy stackable shelf storage.Type: GrantFiled: September 16, 2000Date of Patent: June 7, 2005Inventor: Rosa Brown Salem

Patent number: 6857590Abstract: A spool design for fishing reels is discosed, allowing for the reversible separation of the spool into different parts for the easy removal of old fishing line and wherein a specially configured aperture is exposed upon separation of the spool parts, allowing for the introduction of one end of the line into the interior of the spool. The line can be attached to the inside of the spool, providing for a secure fastening of the line without exposure of the knot to the exterior of the spool.Type: GrantFiled: August 19, 2003Date of Patent: February 22, 2005Inventor: Christian Heesch

Patent number: 6857595Abstract: A motion picture reel is comprised of separable components including a hub formed with a hollow central, cylindrical sleeve and a pair of side retainers on opposing sides of the hub that hold the film therebetween. Each of the side retainers is provided with a central core located on its inner surface. Each core has a generally cylindrical configuration. A prong is formed to project longitudinally from each core parallel to and at a spaced distance from the axis of rotation. A corresponding prong receiving socket is defined in the core diametrically opposite the prong. The cores of the side retainers are inserted into the central, tubular sleeve of the hub so that the prong of each core enters the prong receiving socket or cavity of the other core. A slight counterrotation of the side retainers relative to each other latches the hooks on the ends of the prongs into the sockets.Type: GrantFiled: August 25, 2003Date of Patent: February 22, 2005Inventor: Robert J. Schaefer

Patent number: 6676069Abstract: A holiday light storage system, for storing holiday string lights, having a central hub and extension hubs. The central hub has a pair of parallel flange disks and a core extending perpendicularly between the flange disks. The core allows adjustment of the relative distance between the flange disks. End bores extend through the flange disks coaxially into the core. The extension hubs each have a flange ring and an extension core. The extension core has a threaded end opposite the flange ring for attaching into one of the end bores of the central core. A handle is selectively axially attachable in one of the end bores. The system is configurable by the user according to the storage needs of the user.Type: GrantFiled: April 3, 2002Date of Patent: January 13, 2004Inventor: Eleanor Jewel Davis

Patent number: 6343765Abstract: A two-piece reel structure for taking up an elongated tape, such as a magnetic tape, a film and the like, is provided. The reel includes two similar halves, each of which includes a frustum-shaped central shaft portions. A bottom plane of each frustum is provided with a plurality of engaging means and receiving holes. Each of the engaging means includes a hook portion adapted to engage with a flat projection in the receiving hole on another half reel and a tongue portion located at one end of the hook portion and adapted to press a free end against an edge of the receiving hole opposite to the flat projection to prevent the hook portion from disengaging from the flat projection. By engaging the engaging means on a first half reel with the receiving holes on a second half reel and then turning the two half reels in opposite directions, the two half reels can be easily and firmly connected to each other to provide a complete reel.Type: GrantFiled: October 13, 2000Date of Patent: February 5, 2002Assignee: Lucidity Technology Co., Ltd.Inventor: Chi-Jui Wen
