Abstract: A box spring assembly includes a base frame, a top wire grid and a plurality of modular wire springs interconnecting the top wire grid and the base frame. The modular wire springs each comprises a unitary wire formed into an inverted U-shaped configuration with the closed end of each U-shaped spring having two edge connector bars and a diagonally extending central connector bar interconnected at its opposite ends to the edge connector bars by attachment segments. The closed end of the modular spring is snap-fit to the top wire grid so each of the edge connector bars supports separate portions of the top wire grid at intersections within the wire grid. The vertical legs of the modular spring include at least three torsion bars and two edge loops of differing radii. The edge loops, because of their differing radii impart differing softness or deflection characteristics to the modular springs.

Abstract: A bedding foundation unit having a top planar portion defined by two pluralities of spaced parallel grid wires, and a rigid frame spaced apart from the top planar portion by a plurality of modular springs. Most, if not all, of the modular springs extend longitudinally of the foundation and are connected to the top planar portion in a snap-fit manner, each snap-fit end of each modular spring being held in place by three grid wires above and one grid wire below the snap-fit end.

Abstract: An apparatus for forming and assembling spring interiors is provided in which, in the preferred embodiment, adjustable reforming dies adjacent a cutting station lengthen the supporting structure of a bridging portion of the coil band that interconnects coils near the end of the band to compensate for the change of length caused by the cutting of the endmost bridging portion separating spring assemblies. Adjustable dies are also provided to vary the length of the bridging portions when they are initially formed. The coils are interlaced at a lacing station from continuous lacing coil bands.

Abstract: A knock-down chair back bracket assembly allows for removably securing a chair or sofa back to a chair or sofa base. The bracket assembly comprises a pair of matingly tapered interfitting brackets, one of which attaches to a base of a piece of seating furniture and the other of which attaches to a side of a back of a piece of seating furniture. The base mounting bracket has a pin at an upper end which is cooperable with a double cam lock lever pivoted to an upper end of the back slide bracket. The double cam lock lever has two cam surfaces one of which cams the mounting and slide brackets into fixed engagement and the other of which cams the brackets out of fixed engagement.

Abstract: A pocketed coil spring assembly for use in the manufacture of mattresses or cushions or the like comprising a plurality of longitudinally extending strips of integrally connected closed fabric pockets each containing at least one helically coiled wire compression spring having its axis disposed transversely of the strip, and wherein each of the strips contains a single band of interconnected springs formed from a single length of wire into a plurality of interconnected helical coil springs. In the preferred embodiment of the invention, each strip of spring containing pockets is spaced from each adjacent strip by a ply of resilient foam material, and each of the plies of resilient foam material are secured to the sidewalls of adjacent strips.

Abstract: A spring interior comprising a plurality of longitudinally extending bands of springs disposed side by side and connected together by helical lacing wires in the top and bottom faces of the bands. Each band of springs comprises a single length of wire formed into a plurality of substantially vertical coil springs interconnected by interconnecting segments of wire located alternately in the top and bottom faces of the bands. The coil springs of each row are interconnected by interconnecting segments with the adjacent coils of the same row. The interconnecting segments comprise a planar bridging portion which extend generally lengthwise of the row and arcuate end sections which extend generally transversely of the row. The arcuate end sections are planar and connect the coil springs to the bridging portions of the interconnecting segments. The arcuate end sections are of approximately the same radius as the coil springs to which the arcuate end sections are connected.

Abstract: A clinical bed system for monitoring and recording movements of a person while reclining or sleeping on a bed of the system. The bed includes an air mattress having multiple isolated air-filled zones. Attached to each of these zones is a pressure-responsive readout device which is operative to read out and record pressure changes resulting from movement of a person reclining on the air mattress.

Abstract: A bedding mattress spring assembly comprising rows of coil springs laced together by helical lacing wires and having border wires secured around the periphery of the assembly in the top and bottom planes of the assembly. The border wires are secured to the edgemost coil springs by sheet metal clips. Extending between the border wires are edge support springs which are secured to the border wires by U-shaped channels formed in the ends of the edge support springs.

Abstract: A nestably stackable bedding foundation assembly which replaces the traditional border wire and disposed coil spring foundation assembly in a so-called box spring. The nestably stackable foundation assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping.

Abstract: A hypoeutectic aluminum silicon magnesium alloy includes 4-5.5% silicon, 0.15-3.5% magnesium, 0.005 to 0.08% phosphorus and aluminum. The presence of the phosphorus causes formation of a spherical percipitates of silicon magnesium and the aluminum. The phosphorus suppresses the magnesium silicon aluminum eutectic which allows the aluminum to remain liquid for a longer period of time and consequently providing a better fill of casting during the time the alloy is solidifying in a die or a mold. This alloy which preferably includes nickel is particularly useful for marine, hydraulic and refrigeration components.

Abstract: An assembly for cantilevered connection of a display header to a gondola display rack includes two uprights braced to the gondola display rack in vertical spaced relation. Each upright rigidly supports a cantilevered arm that includes a lower section and an upper section hingedly raisable with respect to the lower section. Brackets located at the free ends of the upper sections are adapted to support the sides of a triangularly shaped display header. The upper sections may be hingedly raised with respect to the lower sections to independently vary the vertical level of the ends of the mounted display header. By providing two brackets on the hingedly raisable upper sections, the assembly accommodates quick and easy connection and disconnection of two display headers located side-by-side in a row at the desired vertical height.

Abstract: A chilled beverage display bin for containing and displaying iced beverage products. The bin comprises a stand and a bucket or beverage display container contained internally of the stand. A translucent or transparent drainage hose is connected to the bottom of the bucket and extends through the stand into a channel formed on the exterior of the stand such that the hose functions as a telltale of the level of liquid in the container, and when removed from the channel, facilitates drainage of liquid from the container without the need for a flow control valve.
