RESILIENT MATTRESS FOR SEATS, CUSHIONS, OR OTHER APPLICATIONS Filed Oct. 29, 1937 a 2 Sheets- Sheet 2 Patented Jan. 13, 1948 UNITED STATES PATENT OFFICE RESILIENT MATTRESS FOR SEATS, CUSH- IONS, OR OTHER APPLICATIONS Application October 29, 1937, Serial No. 171,799 In France October 29, 1936 Section 3, Public Law 690, August 8, 1946 Patent expires October 29, 1956 '2 Claims.

This invention relates to springs and more particularly to an improved spring assembly for use with beds, seats, couches and the like.

One object of the invention is to provide a spring assembly employing springs which are interconnected so that said springs will be caused to cooperate efiiciently for supporting a mattress, cushion or the like.

Another object of the invention is to provide a spring assembly which is of such construction that the number of resilient elements is materially reduced without affecting the supporting surface.

In the drawings forming a part of my application:

Figure 1 is a top plan view showing a plurality of spring elements arranged in rows and showing the connecting wire as it would appear in engagement with alternate coils of the rows of spring elements.

Figure 2 is a side elevation showing portions of the coils,

Figure 3 is a detail top plan view, on an enlarged scale, showing coils of the connecting wire,

Figure 4 is a detail perspective view, on an enlarged scale, showing one of the coil elements eX- tended to form the connecting wire,

Figure 5 is a side elevation showing one of the coil elements,

Figure 6 is a top plan view of the coil element shown in Figure 5,

Figure '7 is a side elevation of the coil element of Figure 5 and showing certain of the coils of said element as they would appear bent to define a portion of the connecting wire,

Figure 8 is a top plan view of the coil elements seen in Figure 7,

Figure 9 is a side elevation of the coil element of Figure 5 and showing said coil element extended further to define an additional coil or loop for the connecting wire, and

Figure 10 is a top plan view of the coil element shown in Figure 9.

Referring now to the drawings, wherein like numerals of reference will be seen to designate like parts throughout the views, the numeral i indicates a close wound helical winding or coil. The coil l is formed of wire which is resilient but is capable of being bent or deformed. In carryin out the invention, two convolutions of the: coil or winding l, as indicated at A, are grasped between the fingers and are bent outwardly to define straight portions A The following circular convolution is then bent to define a short straight portion on the other side of the coil or."

winding l. The operation is continued in this manner by successively bending through to the left and to the right, alternately, of the winding, and pivoted alternately about diametrically opposed points. After bending the convolutions in the manner described, a series of juxtaposed rings 2 is formed. The method of construction above described is carried out by hand in order to enable the formation of the linkage to be better understood. It is obvious that machinery may be employed to bend the convolutions to define the desired linkage.

Figures 5 and 6 show in elevation and plan view, the helical winding from which the wire linkage will be manufactured. I0 is the upper end of the winding and II to I! are points of the winding spaced one and one-half convolutions apart and thus defining sections comprising each one and one-half convolutions. The uppermost section (comprised between points 10 and H, is now bent 180 to the left around the point H, as shown by the arrow in Figure 7. Figure 8 is a plan view of Figure 7. The second section (comprised between the points II and I2) together with the first section, is then bent 180 to the right around the pointslZ as shown in Figure 9. Figure 10 is a plan view of Figure 9.

The operation is continued in the same manner by bending the wire alternately 180 to the left and right, around the points l3, l4, I5, l6 etc.

In Figure l, the reference numeral 4 represents deep coiled springs. The wire linkage 3, 6 and 1 engages the uppermost convolutions of these springs.

It is desired particularly to point out that the spaced rows of springs are interconnected by continuous wire which is bent so as to form ring shaped loops directed alternately to the right and to the left, said loops being inserted alternately under the uppermost convolutions of the springs in the left and right row, these two rows being thus securely connected by the continuous interlacing wire which also completes the surface of the assembly between said rows of springs. This construction is cheap to manufacture, is capable of easy mounting, and provides for a very advantageous resilient interconnection or bonding of the spring elements at the surface of the device. Accordingly, uniform support for a mattress by the device will be assured.

Having thus described the invention, what is claimed as new is:

1. A device of the class described comprisin parallel spaced rows of coiled springs, and interlacing means connecting the upper terminal convolutions of alternate springs of each row of springs, said interlacing means comprising a single continuous wire strand bent into a series of circular loops lying in a single row in a horizontal plane, said wire being bent for interlacing one of the loops in one upper terminal convolution and said wire being bent in an opposite direction for engaging another of the circular loops in an alternate opposite upper terminal convolution, said interlacing means defining crossings on alternate sides of the successive loops, said interlacing means being hooked at the crossings of the wire to the terminal convolutions for forming a cnnection between the spaced rows of springs.

2. A device of the class described comprising parallel spaced rows of coiled springs, and interlacing means connecting the upper terminal convolutions of certain of the springs, said interlacing means comprising a continuous wire strand bent alternately clockwise and anticlockwise to ANDRE AUBY.
