14 Claims. (Cl. 139-410) This invention relates generally to improvements in fabrics and method of making the same and, more particularly, to improvements in inflatable mattress fabrics and method of making the same.

Mattress fabric generally is formed of a pair of Woven laterally spaced fabrics interconnected by intermediate threads extending therebetween, the length of the latter between connected portions thereof determining the spacing apart of said pair of fabrics with said spacing being limited to a maximum substantially corresponding to the width of the series of gages on the loom. It is accordingly the primary aim and object of the present invention to provide mattress fabric formed of a pair of fabrics which are spaced apart a distance substantially greater than the width of the series of gages on the loom on which said fabric is made.

It is a further object of the present invention to provide mattress fabric of the aforenoted character which readily lends itself to the formation of inatable containers, for example, said containers using less material for a given volume than heretofore used containers of this character.

It is yet another object to the present invention to provide an improved method of making the fabric material of the aforenoted character, said method utilizing conventional apparatus in its entirety.

The above and other objects, features and advantages of the present invention will be more fully understood from the following description considered inconnection with the accompanying illustrative drawings.

In the drawing which illustrates the best modes now contemplated by me for carrying out my invention:

Fig. 1 is a diagrammatic View of a loom illustrating one step in the formation of the fabric material of the present invention;

Fig. 2 is a View similar to Fig. l illustrating a further step in the formation of the fabric material;

Fig. 3 is a view similar to Fig. 2 illustrating still another step in the formation of the fabric material;

Fig. 4 is a view similar to Fig. 3 illustrating yet another step in the formation of the fabric material;

Fig. 5 is a diagrammatic view of the fabric material illustrating the step of expanding the spacing of the component fabrics thereof;

Fig. 6 is a view similar to Fig. 5 illustrating a modified method of making a fabric material; and

Fig. 7 is a fragmentary top plan view of the fabric material formed according to the present invention.

Referring to the drawing in detail, and more particularly to Fig. 5 thereof, the mattress fabric 10, formed according to the present invention, comprises a pair of woven fabrics 12 and 14 having anintermediate thread 16 extending therebetween and woven thereto, said pair of fabrics being disposed in laterally spaced confronting disposition with the intermediate thread 16 being transversely disposed between the fabrics 12 and 14. In accordance with the present invention means are provided for temporarily supporting the thread 16 inter- 2,848,018 Patented Aug. 19, 1958 ice mediate woven portions thereof relative to the pair of fabrics 12 and 14 so that on the release of said intermediate portions from temporary support the spacing between the fabrics 12 and 14 may be increased from the spacing indicated at 10' to the spacing indicated at, 10. One form of method of making the mattress fabric 10 will now be described in detail, said method utilizing conventional apparatus in its entirety.

Thus the loom 20 shown in the drawing is conventional in all respects and is provided with a series of gages 22 which are disposed warp-wise thereof, said gages being supported by the support members 24 and 26 in a conventional manner. Ground warp threads A, B for the top fabric 12 are shown passing over the guiding roller 28 and about the guiding roller 30 and similarly ground warp threads C, D for the bottom fabric 14 are shown passing over the guiding roller 32 and about the guiding roller 34. A suitable thread supply will be provided for the formation of the intermediate Warp thread 16, the thread E supplied thereby being illustrated passing over the roller 36. In the illustrated embodiment the intermediate thread E is shown associated with heddle 40, thread A is shown associatedwith heddle 42, thread B is shown associated with heddle 44, thread C is shown associated with heddle 46, and thread D is shown associated with the heddle 48, said heddles being diagrammatically illustrated in Figs. l through 4. Each of the heddles is provided with suitable eyes and the threads of the fabric 10 pass through said eyes. Each of the series of heddles which carry the threads as aforenoted is provided with its separate harness frame (not shown) and is operated by any suitable conventional mechanism, in accordance with the weave desired. A reed 50 is provided on` a swinging lay 52 and said apparatus operates in the conventional manner as will be readily apparent to those skilled in the art. It will be understood that the weaving of the mattress vfabric 10 takes place at area 54 of the series of gages 22 and the latter determine the spacing apart-of the fabrics 12 and 14. Thus in conventional weaving of mattress fabric the distance between the fabrics 12 and 14 will substantially correspond to the width of the series of gages 22 and in accordance with the present invention means are provided to substantially increase said distance or spacing.

The threads A and B are adapted to be interwoven on loom 20 to form the fabric 12 and the threads C and D are adapted to be interwoven on said loom'to form the fabric 14, the intermediate warp thread E being interwoven with the threads A, B, C and D in a manner to be described in detail hereinafter. The weft threads G are interlaced with the warp threads A, B, C and D in a conventional manner whereas the weft threadsF are adapted to temporarily support the intermediate thread E relative to the fabrics 12 and 14. In Fig. 1

heddles

40, 42 and 44 are shown positioned so as to dene a shed 60 and the weft thread F is thrown through said shed by a shuttle in the conventional manner. Thus at this stage of the weaving operation the threads A and B will be positioned below the weft thread F and the intermediate thread E will be positioned thereabove. Thereafter the weft thread'F will be layed or beat into position in the conventional manner so as to occupy the position F' shown in Fig. 2. The intermediate thread E will be looped as illustrated in Fig. 3 and denoted by 68 and the weft thread F will extend through said loop. As shown in Fig. 2, in a further stage of the 'Weaving operation the

heddles

40, 46 and 48 will be positioned to define the shed 62 and a suitable shuttle will be actuated to project the weft thread F therethrough. Thus the temporary weft thread F" will be disposed between the threads C and D on one side and the intermediate thread E on an opposite side whereby it will be apparent that the weft thread F is integrated with fabric 14 in a similar manner to the integration of the weft thread F with fabric 12. Thereafter the apparatus will be operative to position the weft thread F" to the position F" as shown in Fig. 3 whereby it will be apparent that the temporary weft threads F and F'" will support portions of the intermediate thread E relative to the fabrics 12 and 14. In Fig. 3 the heddles are shown disposed in a position so as to define the shed 64 through which a weft thread G is projected, said weft thread being shown positioned above thread B and below threads A and E. Similarly a weft thread G will be projected through the shed 66 which is defined between the threads C and D of the fabric 14. Thus in the weaving stage illustrated in Fig. 3 the weft thread G will be interwoven with the threads A, B and E with the threads A and E positioned thereabove whereas the weft thread G will be interwoven with the threads C and D with the latter thread being disposed outermost. In the next sequence of operations the position of the threads A, B and E relative to the weft thread G will be reversed whereby the thread B will be disposed outermost relative to said weft thread. Similarly the

heddles

46 and 48 will be so disposed as to reverse the position of threads C and D relative to weft thread G with thread C being disposed outermost relative to said weft thread. It is here to be noted that the looped portions 68 of the intermediate thread E are not interwoven with their associated fabrics 12 and 14 so that said looped portions are supported relative to said fabrics solely by the temporary weft threads F. Thus the

portions

70 and 70 of the intermediate thread E are interwoven with the fabrics 12 and 14, respectively, during the weaving of the latter and

portions

72, 74 and 76 of the thread E between

interwoven portions

70 and 70 thereof are temporarily supported relative to the pair of fabrics 12 and 14. Thus the portion 70 of the intermediate thread E is interwoven with the fabric 12 and the portion 70 of said intermediate thread is interwoven with the fabric 14 with the

portions

72, 74 and 76 of the thread E intermediate the interwoven portions 70 and 70' thereof being temporarily supported by the association of the looped portions 68 of said intermediate thread with the temporary weft threads F as aforedescribed. It is to be noted in the aforedescribed embodiment the weft threads F are disposed outwardly of the fabrics 12 and 14 of the mattress fabric After the aforedescribed weaving operations are completed to form fabric 10', the weft threads F are removed in any desired manner whereby to release the looped portions 68 of thread E from temporary support relative to the fabrics 12 and 14. On the removal of the supporting weft threads F the

thread portions

72, 74 and 76 may be expanded so as to define the transversely extending intermediate thread 16, shown in Fig. 5. Thus in the illustrated embodiment the fabrics 12 and 14 may be expanded to substantially three times the spacing corresponding to the width of the series of gages 22. It will be readily apparent that any desired spacing between the fabrics 12 and 14 may be obtained by the aforedescribed method, which is given by way of illustration only. Thus the removal of the supporting weft threads F will permit the expansion of the fabric 10' to the condition 10 as shown in Fig. 5. Accordingly the sole function of the weft threads F is to temporarily support the looped portions 68 of the intermediate thread E so that the

portions

72, 74 and 76 of said intermediate thread may be expanded on the removal of said weft threads to define the intermediate thread 16 which is of a length that substantially corresponds to three times the width of the gages 22.

From the above it will be apparent that warp and weft threads are interwoven to simultaneously form the pair of fabrics 12 and 14 which are disposed in laterally spaced confronting disposition with the spacing corresponding to the Width of the series of gages 22 prior to L the removal of weft threads F. The intermediate thread E is woven with the warp and weft threads of the pair of fabrics 12 and 14, respectively, in succession, during the weaving of said pair of fabrics with said thread extending transversely between said pair of fabrics.

With reference to Fig. 6, there is shown a slightly modified form of fabric 10 which is woven similar to the fabric 10 aforedescribed except in the respects now to be specifically described in detail. The thread portions 68 of the intermediate thread E are looped in a conventional manner and the weft threads f and f' are projected through said looped portions whereby it will be apparent that said weft threads will be disposed inwardly of the fabrics 12 and 14 and outwardly of the gages 22 for support by the latter. Accordingly when the weft threads f and f are released from support by the edges 23 of the gages 22 the fabrics 12 and 14 may be laterally spaced apart substantially corresponding to the condition 10 shown in Fig. 5. Thus the threads f and f are released from support by the gages 22 when the fabric material is drawn therefrom so as to permit the increase of the lateral spacing between the fabrics 12 and 14 as aforedescribed. Accordingly in the embodiment illustrated in Fig. 6 it is not necessary to remove the weft threads f and f as said threads will be disposed between the fabrics 12 and 14 and will be accordingly hidden from View in finished articles formed from the fabric material 10. Thus in the embodiment illustrated in Fig. 6, portions of the thread E intermediate interwoven portions thereof are temporarily supported relative to the fabrics 12 and 14 by means of the gages 22 so when the fabric material is drawn from said gages the weft threads f and f will be released from support thereby whereby to permit the increase of the lateral spacing between the fabrics 12 and 14. As aforenoted the fabrics 12 and 14 may be spaced apart any desired distance and the aforedescribed specific embodiments are given by way of example and not by way of limitation.

The fabric material 10 may have the pair of fabrics 12 and 14 coated or impregnated with any suitable fiuid impervious material such as latex, plastic, or the like whereby articles fabricated from said material will bc fluid impervious. Thus, as shown in Fig. 7, the area 11 of fabric 10 is suitably coated with a fluid impervious material whereby it will be apparent that articles fabricated of such material will be fiuid impervious. As shown in Fig. l, the fabric 10' leaving the gages 22 will be drawn by a suitable take-up roll 78 which is positioned forwardly of the series of gages 22.

Any suitable threads may be used to form the fabric material 10 and the latter may be used to form a multitude of articles, for example iniiatable mattresses and inflatable containers. Thus the fabric 10 may be fabricated to form containers for carbon dioxide and the like for fire extinguishing purposes or said containers may be used to contain fuel such as gasoline and the like. It will be understood that the aforedescribed mattress fabric 10 readily lends itself to the formation of containers and the latter will use less material for a given volume then the heretofore used containers of this character in that said containers may be formed of a substantially greater depth without the integration of a plurality of such containers which must utilize more material for the same volume. Thus the aforedescribed method readily lends itself to the formation of individual containers which have a depth which is not limited to a depth corresponding to the widthwise dimension of the gages 22.

Thus the aforedescribed mattress fabric 10 is formed of a pair of fabrics 12 and 14 which are spaced apart a distance substantially greater than the width of the series of gages 22 on the loom 20 on which said fabric is made. It will be understood that the loom 20 on which the fabric material 10 is made is conventional in all respects and said fabric material may be made on any conventional weaving apparatus such as a Dobby or Jacquard loom 'or any other loom having conventional shed control apparatus.

While I have shown and described the preferred embodiment of my invention, it will be understood that various changes may be made in the present invention without departing from the underlying idea or principles of the invention within the scope of the appended claims.
