Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
In a method for forming a predetermined curved shape from multiple pieces without the use of a jig, form or press, the steps comprising: (a) forming the multiple pieces with opposite glue surfaces, (b) selecting an angular relationship for the glue surfaces of each piece to mate with glue surfaces of adjacent pieces and form the predetermined curved shape, (c) aligning internal passages extending between the glue surfaces of the respective pieces, (d) applying glue means to the glue surfaces, (e) routing a tensioning cable means through the aligned passages, (f) connecting tensioning devices at each end of the cable means for bearing against end pieces of the curved shape, and (g) applying tension to the cable means by the tensioning devices whereby the multiple pieces are drawn into the predetermined curved shape with pressure applied between adjacent glue surfaces.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
42 words
The method of claim 1 wherein a plurality of aligned internal passages are formed through the multiple pieces, a tensioning cable means being routed through each of the plurality of aligned internal passages and similarly connected at its ends with tensioning devices.
Claim 4
Dependent Claim
31 words
The method of claim 1 wherein proper alignment of adjacent glue surfaces and strength of resulting glue joints are facilitated by forming reciprocally shaped mating surfaces on the adjacent glue surfaces.
Claim 5
Dependent Claim
33 words
The method of claim 1 wherein the tensioning cable means is routed through tubing means inserted through the aligned internal passages in the multiple members so that the cable means may be removed.
Claim 6
Dependent Claim
24 words
The method of claim 4 wherein cross sections are removed from the curved shape for use in mass production of products having curved components.
Claim 7
Dependent Claim
42 words
The method of claim 5 wherein a plurality of aligned internal passages are formed through the multiple pieces, a tensioning cable means being routed through each of the plurality of aligned internal passages and similarly connected at its ends with tensioning devices.
Claim 8
Dependent Claim
36 words
The method of claim 6 wherein the tensioning cable means is routed through tubing inserted through each of the plurality of aligned internal passages in the multiple members so that the cable means may be removed.
Claim 9
Dependent Claim
10 words
The product of the method of claims 4 or 5.
