Abstract
Abstract A pitched wooden truss comprises lower and upper chords interconnected by a plurality of web members. The upper chord includes two wooden sections arranged end to end at a predetermined angle to form a central ridge. The adjacent ends of the chord sections are formed with laterally offset, overlapped, convexly arcuate tongues and cooperating concavely arcuate recesses. Securing means secure the tongues to each other in overlapped position. Preferably, the adjacent ends of the chord sections comprise pieces of densified laminar wood.

Claim 1
Independent Claim
102 words
The method of making a structural wood product which comprises: a. providing a plurality of wood laminae, b. applying glue to the faces of the laminae, c. laying the laminae face to face to form a stacked assembly, d. including between confronting end portions only of selected laminae of the assembly a glue-impervious barrier sheet, e. pressing the assembly and permitting the glue to set, and f. cutting across a side face of said end portion of the resulting glued laminate to the plane of the barrier sheet, thereby cleanly separating the cut-away portion only of the laminate from the body thereof.
