Patent number: 7536763Abstract: A core adapter formed as a hollow cylindrical sleeve. A plurality of apertures extend through the sleeve, parallel to the sleeve's longitudinal axis. A plurality of radial apertures are formed in the sleeve for each longitudinal aperture. Each radial aperture is perpendicular to sleeve's axis and intersects a longitudinal aperture. Studs are provided in each radial aperture, initially recessed beneath the sleeve's outer surface. The sleeve's outside diameter is sized for insertion into a 6-inch inside diameter core. The sleeve's inside diameter is the same size as a 3-inch inside diameter core. The adapter is inserted into a 6-inch core until it is flush with the end of the core. Wedge-tipped bars are driven into each of the adapter's longitudinally aligned rows of studs, and against the bottom of each stud, thereby driving the studs perpendicularly away from the sleeve's axis into the core.Type: GrantFiled: April 19, 2006Date of Patent: May 26, 2009Assignee: Catalyst Paper CorporationInventor: Douglas Henry Offerhaus
