Abstract: A reinforcing structure for the corners of innerspring assemblies comprising spaced parallel parts disposed diagonally across the top and bottom sides of the innerspring assembly, spring members at the opposite ends of the spaced parallel parts disposed between the top and bottom sides which yieldably resist displacement of the top and bottom sides relative to each other and clips fixing the structures to the top and bottom sides of the assembly. The spring members are torsion springs comprising a coil and angularly disposed arms and these are disposed with the arms situated in the planes of the sides and ends of the assembly. Optionally, the top and bottom parts are longitudinallly adjusted to vary the distance between the spring members.

Abstract: A spring assembly embodying along the front edge a row of coil springs, each of which has end loops and intermediate the end loops a series of turns which diminish in diameter from the top to the bottom, the loop at the top being inclined to the axis of the coils and providing in conjunction with an upwardly bent portion of the border wire at the top of the assembly a supporting barrier at the front edge of the assembly such as to retain a cushion in place under conditions tending to slide the cushion forwardly.

Abstract: The combination with a spring assembly of pairs of structures designed to be applied transversely to the top and bottom supporting surfaces at one or more longitudinally spaced intervals to enhance the resistance to sinking of the supporting surfaces, bowing at the longitudinal sides and collapse between the surfaces at the longitudinal sides comprising pairs of elongate parts which extend transversely across the assembly at the top and bottom sides from one longitudinal side to the other, said parts being transversely inextensible and resistant to flexing and at one end thereof a polygonal structure disposed between the border wires in the plane of the sides, two sides of which, the top and bottom, are parallel to the border wires and the other two sides of which embody oppositely disposed spring arms.

Abstract: The combination with a spring assembly of pairs of structures designed to be applied transversely to the top and bottom supporting surfaces at one or more longitudinally spaced intervals to enhance resistance to sinking of the supporting surfaces, bowing at the longitudinal sides and collapse between the surfaces at the longitudinal sides due to pressure applied perpendicular to the supporting surfaces, said structures each comprising a stiff, inextensible wire of circular or flat cross section resistant to flexing and at one end a compression-resistant spring, said structures being disposed in pairs with the one structure crossing the top and the other crossing the bottom and with the compression-resistant spring of one situated between the supporting surfaces at one side and of the other situated between the supporting surfaces at the other side and fasteners connecting the structure to the assembly.

Abstract: A spring assembly comprising, spaced pairs of crossing wires welded at their intersections such as to form a dimensionally stable structure wherein the pairs of crossing wires define seats for attachment thereto of the end loops of coiled springs, characterized in that at least two of the wires of the seats are spaced apart a distance less than the distance of the diameter of the end loops and contain deviations perpendicular to the plane of the structure providing longitudinal downwardly facing openings and an upwardly facing opening between the downwardly facing openings and wherein the end loops have arcuate portions which pass through the downwardly facing openings from the inner side outwardly and deviating portions which pass through the upwardly facing openings from the outer side inwardly and wherein the distance between the deviating portions and the end loops is less than the distance between the wires.

Abstract: The method of making a grid of a predetermined length embodying crossing longitudinally and transversely extending spaced parallel wires welded at their crossings wherein the portions of the longitudinally extending wires between the transversely extending wires contain depressions for receiving attaching elements at the ends of coiled springs, comprising forming the grid with the transverse wires spaced in the longitudinal direction of the grid so that any whole number of spaces in the longitudinal direction exceed the length of the assembly and then forming the depression in the portion of the longitudinally extending wires between the transversely extending wires by an amount such that collectively they reduce the distance between the transversely extending wires so that a whole number of the spaces between the transversely extending wires correspond to the length of the assembly desired.

Abstract: Apparatus for stacking spring assemblies produced on a machine for making spring assemblies wherein the coils are connected by lacing wire, comprising a table onto which the spring assemblies are discharged, a first conveyor for removing the assemblies from the place of discharge towards a place of stacking, a second conveyor for lifting the successively discharged spring assemblies from the table and placing them in a stack on a dolly, a third conveyor for ejecting the stacked dolly when a predetermined number of spring assemblies have been deposited thereon and drive mechanisms for taking and synchronizing the successive operations.
