Patent number: 6779313Abstract: A boxable corner bead for finishing drywall corners that is made from two flanges with a protruding nose section. This bead can be made in regular, bullnose, or flex trim type arrangements. Once the bead is attached to a drywall corner, it can be mudded on both sides of the corner without waiting for the mud on the first side to dry. This is because of the shape of the nose which allows a mud dispensing box to apply mud on one side without getting mud on the nose. The box can then be immediately moved to the other side, where that side can be mudded. The nose itself is prepared to directly receive paint or texture, and hence does not need any mud. The flex-trim version has a raised trapezoidal section with a V-groove cut in the back. The bead hinges around the V-groove to match any corner angle. Both sides can be mudded as with the fixed bead. The beads can be used with both interior and exterior corners.Type: GrantFiled: September 27, 2001Date of Patent: August 24, 2004Inventor: Timothy D. Smythe, Jr.

Then, drywall compound is placed over the strip and finished by a drywall finisher. Perforations, depressions and knurling on the strip allow drywall compound to form, when dry, a mechanical bond to the strip at the joint. The material used to make the strip is preferably a mineral filled polymer, such as talc-filled polypropylene, which is inexpensive and lightweight. The adhesive applied to the joint is preferably one which is specially formulated to bond to polypropylene. The strip is initially extruded into a flat form and a crease is imparted to the center of the strip.

An outer finishing layer of fibrous material that directly receives paint or texture. A pattern of protrusions, ridges, or grooves on the inner surface of the semi-rigid member to avoid the need for an inner material layer. To install one of the pieces, it is selected from stock and cut to length. A flat coat of mud is applied to both sides of an exterior or interior angle, and the trim piece is placed over the mud and smoothed into place. Once, the piece is in place, the edges are feathered once with a small amount of mud and a wide blade. At that point the corner is complete except for drying.Type: ApplicationFiled: March 29, 2002Publication date: August 29, 2002Inventor: Timothy D. Smythe

Patent number: 6438914Abstract: A trim piece for installing at a drywall external right angle corner which is provided with a bullnose corner bead includes an intermediate portion which wraps over the convexly curved portion of the bullnose corner bead and has two edges extending parallel to the edges of the flanges of the corner bead. Two leaves are attached to the intermediate portion of the trim piece at the two edges respectively. The intermediate portion of the trim piece has an interior surface at a first end matching closely the exterior surface of the corner bead and an exterior surface which is convexly curved at the first end and is right-angled at the opposite second end and provides a transition from the convex curve to the right angle between the first and second ends.Type: GrantFiled: October 16, 2000Date of Patent: August 27, 2002Inventor: Frederick J. Robertson

Publication number: 20020108342Abstract: The preparation of a pair of abutting straight edges of a pair of wallboard panels for receiving spackle to provide smooth planar butt joints includes the use of a rotary tool having a tool bit to form a channel extending on both sides of the butt joint after the wallboard panels have been installed. After the formation of the channel, spackling of the butt joint in a conventional manner results in a smooth planar finished surface.Type: ApplicationFiled: February 15, 2001Publication date: August 15, 2002Inventor: Stephen A. Henits
