Abstract: A wood I-beam consists of a web and a pair of parallel flange pieces which are joined to opposite edges of the web. The web has a kerf cut into each of its opposite edges, thereby dividing each edge into a pair of legs. Each flange piece, on the other hand, has a tapered groove cut into it. After glue is applied to the tapered side walls of the grooves for the flange pieces, the opposite edges of the web are inserted into the grooves and then the two flange pieces are forced together. The taper and width of the grooves in the flange pieces is such that the side walls of the grooves bend the legs on the end edges of the web together against the natural resiliency of the wood. As a result, the web edges are urged against the side walls of the groove with sufficient force to enable the glue to set-up into an extremely strong bond.

Abstract: The process for the gluing together of free form wood shapes in which individually pre-cut pieces are drawn into position, and correct, even, gluing pressure is applied by tension taken on a cable which has been routed internally through passages pre-drilled in component members of the finished shape and then connected at each end to take-up mechanisms which rest against the surface of the finished product.
