US4034527A — Log cabin construction

Claim 1

Independent Claim 422 words

A log wall corner construction for use in the construction of corners in the walls of log cabin type structures and the like wherein the walls of such log cabin or the like structures are formed of tongued and grooved planks laid edge to edge, with end portions of said planks arranged in pairs in interlocking overlying relation, a said pair comprising; a first end portion of a first said plank, said first end portion having an end face and inner and outer faces, and upper and lower edges; notch means formed in said first end portion, extending from a said edge to about an intermediate point of said first plank and extending from said inner to said outer face thereof; an interlocking block portion, defined by a portion of said end of said first plank adjacent said notch means; a second end portion of a second said plank, having an end face and inner and outer faces, and upper and lower edges; notch means formed in said second end portion extending from a said edge to an intermediate point thereof and extending from said inner face to said outer face dimensioned to receive said block portion of said first end portion; an interlocking block portion defined by a portion of said end of said second plank adjacent said notch means; two sealing surfaces formed on one said end portion, transversely of the longitudinal axis of said plank adjacent said notch means, one said sealing surface being directed substantially towards said end, and the other sealing surface being directed inwardly whereby to form a projecting shoulder; two sealing surfaces formed on the other said end portion extending transversely of the longitudinal axis of said plank forming a complementary recess being dimensioned and oriented to receive said projecting shoulder on said one end portion, whereby when said two end portions are interlocked with one another with the block portion of one said end portion located within the notch means of the other said end portion , and said block portions overlapping and registering one above the other, said sealing surfaces interengage and abut with one another, and, fastening opening means in said block portions of both first and second end portions whereby fastening means may be interengaged between said overlapping block portions and operable to set up forces operating in a plane parallel to the axis of said planks diagonally across said corner whereby to draw said sealing surfaces into pressurized sealing engagement with said projecting shoulder fitting tightly into said complementary recess.

Claim 2

Dependent Claim 422 words

A log wall corner construction for use in the construction of corners in the walls of log cabin type structures and the like wherein the walls of such log cabin or the like structures are formed of tongued and grooved planks laid edge to edge, with end portions of said planks arranged in pairs in interlocking overlying relation, a said pair comprising; a first end portion of a first said plank, said first end portion having an end face and inner and outer faces, and upper and lower edges; notch means formed in said first end portion, extending from a said edge to about an intermediate point of said first plank and extending from said inner to said outer face thereof; an interlocking block portion, defined by a portion of said end of said first plank adjacent said notch means; a second end portion of a second said plank, having an end face and inner and outer faces, and upper and lower edges; notch means formed in said second end portion extending from a said edge to an intermediate point thereof and extending from said inner face to said outer face dimensioned to receive said block portion of said first end portion; an interlocking block portion defined by a portion of said end of said second plank adjacent said notch means; two sealing surfaces formed on one said end portion, transversely of the longitudinal axis of said plank adjacent said notch means, one said sealing surface being directed substantially towards said end, and the other sealing surface being directed inwardly whereby to form a projecting shoulder; two sealing surfaces formed on the other said end portion extending transversely of the longitudinal axis of said plank forming a complementary recess being dimensioned and oriented to receive said projecting shoulder on said one end portion, whereby when said two end portions are interlocked with one another with the block portion of one said end portion located within the notch means of the other said end portion , and said block portions overlapping and registering one above the other, said sealing surfaces interengage and abut with one another, and, fastening opening means in said block portions of both first and second end portions whereby fastening means may be interengaged between said overlapping block portions and operable to set up forces operating in a plane parallel to the axis of said planks diagonally across said corner whereby to draw said sealing surfaces into pressurized sealing engagement with said projecting shoulder fitting tightly into said complementary recess.

Claim 3

Dependent Claim 119 words

A log wall corner construction as claimed in claim 1 wherein said block portions on said first and second end portions define inner and outer surfaces, the outer surfaces of said block portions being coplanar with the outer faces of said end portions of said planks, and said inner surfaces lying in planes intermediate said inner and outer faces of said planks, and wherein said notch means in said first and second end portions define end surfaces lying in planes spaced from the planes of said end faces of said end portions of said plank by a distance less than the distance between said inner and outer faces of said planks, but sufficient to receive respective block portions therein.

Claim 4

Dependent Claim 39 words

A log wall corner construction as claimed in claim 1 wherein said fastening opening means in respective said block portions are slightly misaligned with one another, when said end portions are interengaged, with their block portions overlapping as aforesaid.

Claim 5

Dependent Claim 39 words

A log wall corner construction as claimed in claim 3 wherein said misalignment of said fastening opening means is procured by forming said sealing surfaces with predetermined dimensions such that said opening means cannot be brought into exact alignment.

Claim 6

Dependent Claim 40 words

A log wall corner construction as claimed in claim 4 wherein said misalignment of said fastening opening means is located along an axis extending through said corner, at an angle of substantially 45° of the axis of both said planks.

Claim 7

Dependent Claim 74 words

A log wall corner construction as claimed in claim 1 wherein said sealing surfaces on said first end portion form a transverse shoulder extending transversely of the axis of the plank and wherein said sealing surfaces on said second log end form a transverse recess extending transversely of the axis of said second plank, said shoulder being shaped and adapted to fit within said recess, when said first and second end portions ae interengaged.
