TWO-FLY FABRIC FOR MATTRESSES OR THE LIKE Filed Aug. 26, 1950 ATTORNEY Patented Mar. 24, 1953 TWO-PLY FABRIC FOR MATTRESS ES- OR THE LIKE John A. MacIntyrc, Barrington, It. I., assignor to U. S. Plush Mills, Inc.', a corporation of Rhode Island Application August 26, 1950, Serial No. 181,665

3 Claims. (Cl. 139-410) This-invention relates to a two-ply fabric such as may be woven on the usual plush loom.

One of the objects of this invention is to provide a fabric which may be used fora mattress or seat by inflating the same.

Another object of this invention is to provide a two-ply fabric which will have the two plies tied together in the manner of tufting all Lin a weaving operation without the need of separate handling. 1 I

Another object of this invention is to provide a two-plyfabric which may be inflated and which will have the plies limited in the amount that they may move one from the other as the pressure of the air is exerted in the space between the plies.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

' Figure 1 is a perspective view of the two plies of fabric shown as connected together by groups of warp threads;

Figure 2 is a sectional view on line 2-2 of Figure 1; and

Figure 3 is a sectional view on substantially line 3--3 of Figure 2; v

Figure 4 is a perspective view of a fin hed cushion; and

Figure 5 is a, diagrammatic view of a modified weave fabric. I

In proceeding with this invention, I weave in a plush loom two plies of fabric and provide connectingLth-readS extending warpwise of the fabric and woven alternately into the opposite plies, and I provide these threads in rows and group these threads leaving spaces of considerable extent between them so that the fabric is connected together in pillars of threads located at widely spaced intervals. The two plies of fabric are then treated with some sort of coating material which makes them impervious to air and then after their edges are sealed, they may be inflated which will provide a mattress or seat or cushion with a tufted effect by reason of the plies bulging outwardly between the pillars of threads which connect together at the spaced plies of fabric.

With reference to the drawings, I0 designates one fabric ply of woven warp and filling threads and I1 "another fabric ply of woven warp and filling threads. As these plies are woven in a plush loom, the cutter which usually severs the connecting threads is removed and the connecting threads designated I2 are woven as at I3 into the ply II and then extend'to the ply II) where they are woven in, as .at I4. These warpwise extending connecting threads then float over the inner surface of the ply In as at It and are woven again into the ply III at 'a spaced interval from theweaving I4 as at It. They then extend across to the other ply I I where they are woven into this ply as at IT, float over this ply H as at I8 and are woven in again as at I9 and then extend across to be woven into the ply III as at 20 andso on along an extended length of the fabric.

The weaving in at the locations such as It is shown in greater detail in Figure 2 where a warp thread is designated 21 ofthe fabric I0 and the filling threads thereof are designated 22. One of the connecting warp threads I2 is shown as being woven in with the filling threads 22 in the area I S and then extend across to be woven in with the filling threads 2-3 which is also woven with the warp threads 24 of the ply I I. This weaving in in the areas such as I6 and I1 consists of each of the groups of warp threads I2 weaving under three threads and over three threads and then extending across to the other ply where a similar weaving takes place, under three threads and over three threads. The warp I2 then extends back to the area I-Ii where a similar procedure occurs and then back to the area I! in the ply I I where a similar proceeding occurs and then the warp threads I2 float as at I8 over a number of warp and filling threads, possibly sixty-four in number and then repeats the operation in th areas I 9 and 20. I r

In the group of warp threads there will be possibly twenty-four, although I have illustrated in V Figure 3 only nine of this group, the number being widely variant. The length of the connecting warp threads such as I2 between the plies of fabric may be anywhere from one-half inch to four inches.

After the fabric is prepared, it is coated with a rubber-like materialto cause the same to be impervious to moisture and air and then the edges are closed as at 21 in Fig. 4 and the same may be inflated by forcing air into the space between the plies of fabric. The pressure of the air will tend to force the areas 25 between the rows of woven connecting threads outwardly so that a tufting effect of the mattress, seat, or cushion provided is formed.

In some cases instead of the weave relation being shown as in Fig. 2, the warp thread 30 will be interwoven with one ply of fabric but passing under one filling thread 3| and over three filling 1. A fabric comprising two outer layers, 'ea'ch composed of interwoven warps and wefts which layers are interconnected by an intermediate set of connecting warps interwoven'into one of said layers and extending therefrom into the other layer and interwoven therein, said connecting,

warps being arranged in groups of a plurality of warps to form tie threads interwoven in said layers at concentrated locations spaced from each other a distance greater than the distance of the space occupied-by the warps of each group in a direction bothfwarpwise andfweftwise of the said outer layers, theportions of said connecting warps between the interwoven portions thereof being floated along the inner surface of said layers in the space between said interwoven portions of said connecting warps whereby said outer layers are connected to each other only at locations spaced from each other in all directions to produce a tufting eifect when separation of the said outer layers is attempted.

2. A fabric as set forth in claim 1 wherein the connecting warps of each group are in greater number weftwise than warpwise.

3. A fabric comprising two outer layers, each composed of interwoven warps and wefts which layers are interconnected by an intermediate set of connecting warps interwoven into one of said layers and extending therefrom into the other layer and interwoven therein, said connecting warps being arranged in groupsiof a plurality of warps to form tie threads interwoven in said layers at concentrated locations spaced from each other a distance greater than the distance of the space occupied by the warps of each group in a direction both 'warpwise and weftwise of the said outer layers, whereby said outer layers are connected to each other only at locations spaced from each other in all directions to produce a tufting effect when separation of said outer layers is attempted.
