Abstract
Abstract Laminated wood strip or plank flooring members are disclosed having adjacent edges of adjacent strip or plank members slightly reverse-beveled, i.e. 2° to 7° from vertical, to tightly fit together to provide precise, flush contact between adjacent upper surfaces of adjacent strips or planks. The strip or plank wood materials are provided in various lengths and various predetermined widths so that the random width and length strip or plank materials can be fitted together to provide a most unexpected and pleasing appearance wherein each adjacent strip or plank member is precisely fitted together and adjacent surface portions are substantially flush, or in contact.

Claim 8
Dependent Claim
43 words
The strip or plank of claim 6 wherein said tongue members extend outwardly from said edges of said strip or plank member a distance less than a depth of said grooves to enable said top surfaces of adjacent panels to contact each other.
Claim 9
Dependent Claim
48 words
The strip or plank member of claim 1 wherein said strip or plank member has four edges and includes two tongue members on two of said edges and two grooves adapted to receive tongue members, from an adjacent strip or plank member, on another two of said edges.
Claim 10
Dependent Claim
135 words
A laminated wood flooring member having a major upper surface, a major lower surface and four edges, two of said edges including tongue members extending from said two edges outwardly beyond said major upper surface, and two of said edges including machined grooves therein each of said two tongued edges including a precision-fit edge surface defined by an edge surface lying between an uppermost edge of said tongues and said major upper surface, wherein said major upper surface is substantially horizontal, said precision-fit edge surface is sloped at least 2° from vertical inwardly from said major upper surface toward said tongue member, said tongued edge and grooved edge machined such that the tongue member of an adjacent strip or plank floats freely within said groove without substantially contacting the internal machined surfaces defining the groove.
Claim 11
Dependent Claim
135 words
A laminated wood flooring member having a major upper surface, a major lower surface and four edges, two of said edges including tongue members extending from said two edges outwardly beyond said major upper surface, and two of said edges including machined grooves therein each of said two tongued edges including a precision-fit edge surface defined by an edge surface lying between an uppermost edge of said tongues and said major upper surface, wherein said major upper surface is substantially horizontal, said precision-fit edge surface is sloped at least 2° from vertical inwardly from said major upper surface toward said tongue member, said tongued edge and grooved edge machined such that the tongue member of an adjacent strip or plank floats freely within said groove without substantially contacting the internal machined surfaces defining the groove.
Claim 12
Dependent Claim

Claim 15
Independent Claim
136 words
A method of manufacturing a wood strip or plank member comprising: securing together a plurality of wood veneers to form a laminate having cross grained adjacent veneers and a major upper surface; machining an edge of said laminate to form a tongue member extending outwardly a predetermind distance from said machined edge; machining another edge of said laminate to form a groove in said another edge, said groove machined to receive a tongue member of an adjacent strip or plank member within said groove, machining said tongued edge between said tongue and said major upper surface to provide a beveled, precision-fit edge surface between said tongue member and said major upper surface, said precision-fit edge surface sloped inwardly from said upper major surface toward said tongue at an angle of at least 2° inwardly from vertical.
Claim 16
Dependent Claim
