Patent number: 6336484Abstract: The present invention concerns a method that is timesaving, more economical and facilitates the handling and processing of short solid wood planks. Tongue-and-groove joints are machined on the short sides of the short green planks enabling their releasable tight assembly in rows for the seasoning process in the kiln dryer. This temporary attachment between adjacent planks prevents exposition of the short sides to the drying air thus avoiding the usual end grain checking on the latter during kiln drying, and eliminates the need of performing any subsequent machining and trimming steps after the expensive kiln drying step. This process then also improves the saving opportunities by increasing the volume of wood drying capacity and by increasing the production of reusable green wood shavings as opposed to unusable wood shavings following the kiln drying operation.Type: GrantFiled: June 1, 2000Date of Patent: January 8, 2002Inventor: Gilles Grenier

Patent number: 5380119Abstract: A resiliently yieldable picture frame corner insert for use with a picture frame corner construction. The corner construction includes first and second elongate frame parts extending at right angles to each other and having juxtaposed end portions and longitudinal axes. Each of the end portions has a hole therein extending perpendicular to the longitudinal axis of the frame part and a slot extending from the hole and through the end portion. The corner insert is secured to the juxtaposed end portions for retaining them in contact with each other. The corner insert is formed as one piece and has first and second web portions disposed in the slots and first and second outer portions disposed in the holes. The web portions are resiliently yieldable with respect to each other and serve to apply yieldable forces tending to urge the juxtaposed end portions into engagement with each other.Type: GrantFiled: June 21, 1993Date of Patent: January 10, 1995Inventor: David M.

Patent number: 5377732Abstract: A technique is provided for joining wood members. A plurality of slits are formed on the end portions of wood pieces desired to be joined, and the end portions are abutted with corresponding slits in alignment to form a common surface. Each of the abutted wood end portions is fixed by temporary fixing means to a desired joining state. Thereafter, an adhesive agent is applied into the interior surfaces of the slits. Connecting plates, e.g., made of a reinforced plastic material coated with the adhesive agent, are inserted into the aligned slits. The adhesive agent is then hardened.Type: GrantFiled: September 23, 1993Date of Patent: January 3, 1995Assignee: Forestry and Forest Products Research InstituteInventors: Tsuyoshi Fujii, Atsushi Miyatake

Patent number: 5371992Abstract: At least one scored screw is driven into the squeak area with a specialized driving bit and an alignment and depth control fixture. The alignment and depth control fixture is used to direct the scored screw to the proper point into the floor so that the scored area is at or beneath the surface of the floor. The driving bit can stop driving the screw at the desired position. After the alignment and depth control fixture is removed, a gripping tool is used to apply force to the screw and break the screw at the prescored position. The barrel of the screw being left in the floor locks the floor or the step to the desired support. One screw or series of these screws in usually an arcuate or a radial fashion around the squeak area, can eliminate the squeak.Type: GrantFiled: April 16, 1993Date of Patent: December 13, 1994Inventor: Jon L. O'Berry

Patent number: 5348066Abstract: Door frames, window frames, baseboards etc are trimmed with solid weed, e.g. oak, trim pieces. The trim pieces are fitted over splines which are screwed to the wall. A jig enables the splines to be located accurately in position. The spline includes no beads, snaps, or other features that would require the oak trim section to flex; instead, the trim is secured by the friction arising from the fit of the spline into a groove cut into the rear face of the trim section. In a variation, a pair of parallel grooves are provided, together with a corresponding pair of splines, which are mounted on a web.Type: GrantFiled: March 23, 1992Date of Patent: September 20, 1994Inventor: Bryan A.

Patent number: RE35327Abstract: The method of converting logs involves cutting each log longitudinally and diametrically at right angles into equal quarter-log segments, the rearranging the quarter-logs so that the arcuate surfaces of the segments face inwardly toward each other, while their cut flat surfaces are positioned to form a rectangle in cross-section. The segments so positioned may be joined together as such, rigid foam plastic insulation may be introduced into the space remaining between the segments, or support bracing and other insulation may take the place of the rigid foam. The resultant converted logs may be used as beams, joists or bearing-wall members; devices for aligning, registering and sealing the converted logs together are provided.Type: GrantFiled: March 9, 1994Date of Patent: September 10, 1996Inventor: Peter Sing
