Abstract
Furniture disclosed herein is substantially constructed of elongated cylindrical wooden members which are connected together by cove joints including a first such member coved at an end thereof to fit conformingly against the curved surface of a second such member at an angle thereto, a hanger bolt secured in and extending from the coved end of the first member substantially through a transverse bore in the second member, and a drive-socketed flanged cap nut engaging the extending end of the bolt and bearing against the opposite curved surface of the second cylindrical member to adjustably compress the cylindrical members together at their conforming fit to stabilize the joint. The flanged nut has a cylindrical portion containing its threads for entry into the bore for centering it under the nut flange, and the flange has an annular appearance skirt extending toward the curved surface of the second wooden member for cutting thereinto and hiding the undersurface of the flange. A furniture manufacturing method in which pluralities of standardized cylindrical members and bolts are prepared complete ready for further assembly to form cove joints, suitably selected members including the bolts are assembled with cove joints to form a particular piece of furniture, and the cap nuts are attached to the bolts and screwed down to compress the members together at the joints to the degree needed to stabilize the joints.
