Abstract
Abstract An elongated board of artificial lumber having a length greater than the width and thickness comprising a mixture of irregularly shaped elongated splinters of wood substantially aligned along the length of the board; a substantial portion of the mixture including splinters from about 2" to 10" long; a sealant coating the surface of the splinters; an adhesive carried on the splinters with the sealant restricting the penetration of the adhesive into the splinters so as to produce hardened layers between the splinters for holding the splinters in an interlocking configuration.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
104 words
An elongated board of artificial lumber having a length greater than the width and thickness comprising: a mixture of irregularly shaped elongated splinters of wood substantially aligned along the length of said board, a substantial portion of said splinters being from about two to eight inches long, a sealant coating the surface of said splinters, an adhesive coating carried on said irregularly shaped elongated splinters with said sealant restricting the penetration of said adhesive into said splinters, said splinters being compressed into an interlocking configuration, with said adhesive coating forming hardened longitudinally extending layers between said splinters holding said splinters in said interlocking configuration.
Claim 2
Dependent Claim
104 words
An elongated board of artificial lumber having a length greater than the width and thickness comprising: a mixture of irregularly shaped elongated splinters of wood substantially aligned along the length of said board, a substantial portion of said splinters being from about two to eight inches long, a sealant coating the surface of said splinters, an adhesive coating carried on said irregularly shaped elongated splinters with said sealant restricting the penetration of said adhesive into said splinters, said splinters being compressed into an interlocking configuration, with said adhesive coating forming hardened longitudinally extending layers between said splinters holding said splinters in said interlocking configuration.
Claim 3
Dependent Claim
120 words
An elongated board of artificial lumber having a length greater than the width and thickness comprising: a mixture of irregularly shaped elongated splinters of wood fibers substantially aligned along the length of said board, said splinters being of irregular cross section having been torn or cut from logs perpendicular to the length of the logs, a substantial portion of said splinters being from 2 to 10 inches long, a sealant coating the surface of said splinters, an adhesive carried on said splinters with said sealant restricting the penetration of said adhesive into said splinters, said splinters being compressed into an interlocking configuration with said adhesive forming hardened longitudinally extending layers between said splinters holding said splinters in said interlocking configuration.
Claim 4
Dependent Claim
120 words
An elongated board of artificial lumber having a length greater than the width and thickness comprising: a mixture of irregularly shaped elongated splinters of wood fibers substantially aligned along the length of said board, said splinters being of irregular cross section having been torn or cut from logs perpendicular to the length of the logs, a substantial portion of said splinters being from 2 to 10 inches long, a sealant coating the surface of said splinters, an adhesive carried on said splinters with said sealant restricting the penetration of said adhesive into said splinters, said splinters being compressed into an interlocking configuration with said adhesive forming hardened longitudinally extending layers between said splinters holding said splinters in said interlocking configuration.
Claim 5
Dependent Claim
33 words
The elongated board of artificial lumber as set forth in claim 2 wherein about sixty percent of said mixture of irregularly shaped elongated splinters are from about 2 to 8 inches in length.
Claim 6
Dependent Claim
96 words
An elongated board of artificial lumber having a length greater than than the width and thickness comprising: a mixture of irregularly shaped elongated splinters of wood substantially aligned along the length of said board, a substantial portion of said splinters being more than two inches long, an adhesive coating carried on the surface of said irregularly shaped elongated splinters in a non penetrating manner, said splinters being compressed into an interlocking configuration with said adhesive coating forming longitudinally extending hardened layers of reinforcing lines running the length of said board and having a honeycomb cross-section configuration.
Claim 7
Dependent Claim
96 words
An elongated board of artificial lumber having a length greater than than the width and thickness comprising: a mixture of irregularly shaped elongated splinters of wood substantially aligned along the length of said board, a substantial portion of said splinters being more than two inches long, an adhesive coating carried on the surface of said irregularly shaped elongated splinters in a non penetrating manner, said splinters being compressed into an interlocking configuration with said adhesive coating forming longitudinally extending hardened layers of reinforcing lines running the length of said board and having a honeycomb cross-section configuration.
Claim 8
Dependent Claim
27 words
The elongated board of artificial lumber as set forth in claim 4 wherein the cross section of said splinters extends up to about three-fourths of an inch.
Claim 9
Independent Claim
113 words
The method of producing artificial lumber comprising the steps of: (a) cutting splinters of about two to ten inches from a log perpendicular to the length of the log, (b) drying said splinters, (c) coating said splinters with a sealant allowing said sealant to dry on said splinters, (d) applying an adhesive to said coated splinters with said sealant restricting the penetration of said adhesive into said splinters, (e) aligning said splinters so that said splinters are substantially parallel to each other, (f) compressing said aligned splinters and said adhesive with pressure into a predetermined shape, and (g) curing said compressed mixture of splinters and adhesive producing a hardened board of artificial lumber.
Claim 10
Independent Claim
113 words
The method of producing artificial lumber comprising the steps of: (a) cutting splinters of about two to ten inches from a log perpendicular to the length of the log, (b) drying said splinters, (c) coating said splinters with a sealant allowing said sealant to dry on said splinters, (d) applying an adhesive to said coated splinters with said sealant restricting the penetration of said adhesive into said splinters, (e) aligning said splinters so that said splinters are substantially parallel to each other, (f) compressing said aligned splinters and said adhesive with pressure into a predetermined shape, and (g) curing said compressed mixture of splinters and adhesive producing a hardened board of artificial lumber.
Claim 11
Dependent Claim
23 words
The method of producing artificial lumber as set forth in claim 6 wherein said sealant used for coating said splinters is sodium metasilicate.
Claim 12
Dependent Claim
