Abstract: A spring element for bedding and furniture which can be constructed in a simple manner but will not tend to come apart in ordinary use. The spring element includes a laterally extending pair of parallel wires and a longitudinally extending pair of parallel wires atop the laterally extending wires. The pairs of wires are welded to one another at their crossing points to form a seat for engaging the open top loop of a coil spring, and the ends of the wires are connected to a framework. Each longitudinally extending wire has a depressed portion between the crossing points extending beneath the laterally extending wires. The top loop of the spring is snapped into engagement with the pairs of wires, so that the top loop is sealed above the depressed portions of the longitudinally extending wires and beneath the laterally extending wires and so that the top of the free end portions of the top loop is biased against the bottom of one of the laterally extending wires.

Abstract: A clinch tool and method for clamping a grid frame to a coil in which a clinch component is fed automatically into a space formed by the tool between the grid frame and coil with the clinch component saddled in position on the grid frame to be bent to retain the coil in a locked condition to the grid frame.

Abstract: A preformed grid of perpendicularly intersecting wires equally or unequally spaced apart and welded together or part of such grid such as a pair of parallel wires and a binding cross wire, are tightly joined together as well as to the top turn or ring of a coil spring by an inverted U-shaped wire clip detached and fed preferably automatically from a cemented group of such clips much like conventional staples. An upper grid wire is arranged to span the ring diametrically while a pair of lower wires parallel to each other are arranged as respective opposed chords of the ring each spaced inwardly at its weld from the adjacent perimeter of the ring just enough to permit the insertion of a clip leg or legs at an inward and downward slant into the space between the perimeter of the ring and the chord portion of the other wire while straddling the spanning wire.
