FABRIC OONSTRUCTED OF LAMINATED COHESIVE INTERWOUND Specification of Letters Patent.

Application filed October 17, 1910. Serial No. 587,629.

To all whom it may concern:

Be it known that IfLAWRENCE A. Sunnns, a citizenof the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Fabrics Constructed of Laminated Cohesive Interwound Members, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. 1

The objects of the invention are to provide a form of fabric which will be possessed of great tensile strength, combined with great flexibility and in which a minimum amount of rubbing or frictional contact of one fibrous member. upon another is obtained, on account of the peculiarities of structure.

The fabric is composed of laminated-cohesive-interwound members which are embedded in a vulcanizable binding material such as rubber, which rovides flexibility without permitting the fibrous members to come into actual contact with each other. The fabric is similar-in construction to that described in my previous application Ser.

No. 540,982 filed January 31, 1910, in which a laminated,unwoven fabric is composed of a series of parallel equally spaced fibrous bands wound upon a mandrel at an angle of approximately to any longitudinal surface line upon which is wound or laid at an angle of approximately, 90 a second similar'series of equally spaced fibrous bands, a third series of similar bands is wound or laid thereon parallel to the first Famed series in such a position as to cover the'spaces between the ands of the first series, and a fourth series parallel to the second series is wound or laid over all to cover. the spaces between the bands of the second series, thus forming an unbroken two ply sheet of fabric, without weaving, braiding, interlacing, or interlock; ing of the bands. Theseveral series thus wound are pressed together so that all the rectangular openings between the bands are.

closed and the edges of one series of bands will engage the edges of the other parallel series of bands so that one series of bandswill not slip or slide over another. In this manner'a two ply fabric is formed, although .it may be made of any plural number of series and can most readily be formedby Patented Apr. 23, 1912.

shown and described in my said application.

The bands of the fabric'hereinafter described arev preferably composed altogether or in part of cords, threads or yarns having a predetermined amount of twist and are designed to be more flexible and to have less frictional action on each other and to beless liable to rupture, abrasion or disintegration from use or age for the purpose designed than the bands described in my former application in which twisted cords or threads or woven reinforcing bands were employed. In this fabric the bands are shown interwound in a two g oup system and a four group system, and each band may be reinforced with, or inclosed in an open mesh fabric, which has the double function of binding. the cords or threads composing the material in close engagement with the bands mesh fabric which are filled with this binding and adhesive materiaL.

The several forms of construction and arrangement of the various fibrous elements and binding material composing the bands is hereinafter more fully described, shown in the accompanying drawings and specifically pointed out in theclaims.

In the accompanying drawings Figure 1 is a plan view of the fabric, formed in a 160111 groupv system, from wo'und bands .formed of longitudinally directed threads or yarns, the threads in each band being united by means of the rubber in which they are embedded; Fig. 2 is an isometrical perspective view of the same showing the bands" in their relative positions prior to being pressed together; Fig. 3 is a plan view of a band broken away to show the outside coating of rubber and a layer of openmeshed netting between layers of thread, and F g. i is a longitudinal section of the same; Flg. 5 is a plan view of a similar band showmg a rectangular net intermediate between layers of threads, and an outer rubber coating; Fig. 6 is a longitudinal section thereof; Fig. 7 is a transverse section thereof en larged; Fig. 8 is a plan view of a fabric formed in a-two group system from parallel,

.75 band together and of retaining the bindingequally spaced interwound bands composed of twisted cords and having threads filling the longitudinal depressions between these cords; Fig. 9 is an isometrical perspective view of the same; Fig. 10 is a transverse section of the same enlarged; Fig. 11 is a plan view broken away and showing a band of threads having open mesh or reticulated fabric adhering upon each side and an outer rubber coating; Fig. 12 is a longitudinal section thereof; Fig. 13 is a transverse section thereof; Fig. 14 is a plan view, broken away, of a similar band of threads but modified by having the open mesh fabric on one side only of the threads; Fig. 15 is a longitudinal section thereof; Fig. 16 is a transverse section thereof; Fi 17 is a plan view broken away to show a band of adhering twisted cords with a layer of open mesh fabric on each side thereof: Fig. 18 is a longitudinal section thereof; Fig. 19 is a transverse section thereof; Fig. 20 is a plan View of a band of longitudinally directed twisted cords, broken away to show a single covering of open meshed fabric and a rubber outer covering; Fig. 21 is a longitudinal section thereof; Fig. 22 is a transverse section thereof; Fig. 23 is a plan view broken away of a modified form in which a band of cabled thread is entirely enveloped in an openmesh fabric of hexagonal mesh, the edges of which overlap upon the band; Fig. 24 is an edge view thereof; Fig. 25 is a plan view of a similar band enveloped in an open rectangular mesh fabric; Fig. 26 is a transverse section thereof; Fig. 27 is a plan view of a band of twisted cords broken away to show two covers of open or reticulated fabric the edges of which extend beyond the band and adhere together; Fig. 28 1s a transverse section thereof.

. In these views 1, 1 are bands composed of adhering yarns. These yarns are laid in rubber or completely coated with rubber which binds them together. The yarns are laid in a parallel longitudinal direction and they have the great advantage of being extremely flexible and not liable to rub upon and abrade each other when the fabric is put to use. The rubber serves to cause the yarns to adhere closely together and also separates them out of actual contact with each other. The manner of applying the rubber or other adhesive material is not a part of this invention and may be accomplished in any manner which. will thoroughly incorporate the rubber among the fibers. These bands are laid in rubber or equivalent adhesive vulcanizable binding material and cohere together therein, but are not interlocked in any manner and without the adhesive binding material would quickly fall apart. The binding material entirely incloses and separates them from actual frictional contact with each other.

In Fig. 1 four series of parallelbands of yarns 1, 1, are shown crossed by four similar series in the reverse direction the memmembers of the bands together.

bers of each series being spaced four band widths apart, and the eight series wound in succession a series in one direction alternating with a series in the other direction to form a four group system of two ply fabric. In Fig. 2 this arrangement is clear and shows the bands 1, 1, before they are pressed together so as to fill all the openings. In the structure shown in Figs. 8 and 9 the bands of each series are spaced only one band Width apart to form a two ply fabric of'a two group system.

In Figs. 2, 3, 4, 5, 6, and 7 a layer or strip 2 of open mesh or reticulated fabric is shown inclosed between two layers of threads. In making the bands from threads or yarns a predetermined number is employed according to the width and thickness of the band required. The spaces or openings between the meshes are completely filled with rubber and hence the mesh serves to retain and bind the rubber coating within the band and provides a protection for the rubber as well as serving to hold the threads closely together 'and to prevent them from spreading apart. 3 is an exterior rubber coating.

In Figs. 11,12 and 13, two layers 2, 2, of open mesh fabric are shown one on each side of the band of threads, thus retaining the coating 8 in place, and aiding the adhesive material in binding the threads together. In Figs. 14, 15, and 16 one exterior layer of open mesh fabric 2 is shown.

In Figs. 17, 18, and 19 a band of twisted cords 0, c, adhering together is shown and two outer bands or strips of open mesh fabric embedded in rubber. In Figs. 20, 21, 22 only one strip of open mesh fabric is shown. In Figs. 23, 24, 25 and 26 the open mesh fabric is shown enveloping the sides and edges of the cabled thread bands. The edges of the open mesh fabric overlap at P upon the sides of the bands and are cemented together in the rubber binding material. In Figs. 27 and 28 the open mesh fabric is shown on both sides of a band of twisted cords adhering together and the edges e of the fabric extend beyond the edges of the band and adhere together, thus inclosing the band.

I do not limit myself altogether to the exact arrangement of bands and open mesh fabric or to the exact character of fabric employed to inclose and bind the fibrous It is essential however that the open mesh fabric should not interfere perceptibly with the flexibility of the bands and that this fabric should bind the fibers together and retain the rubber in close contact therewith.

In Figs. 8, 9, and 10, the bands are shown formed of longitudinally directed parallel cords a, a, coated with rubber 3, and cabled threads If, t, are shown filling the interstices between the cords and embedded in the rubber, thus reinforcing. the rubber and assistfabric, a rubber binding material in which,

ing it in separating the cords out of frictional engagement with each other. It isv obvious that to arrive at any predetermined thickness and Width of the band of yarns or threads they may be impregnated with or embedded in the rubber binding material or other adhesive material and passed through suitable forming rolls for the purpose intended.

"Having described the invention what I claim as new and desire to secure by Letters Patent is 1. In an unwoven laminated fabric formed of cohering equally spaced fibrous I bands crossing each other to form a two ply material filling the interstices in said open mesh fabric.

' 2. In a fabric, series of equally spaced parallel bands of threads cohering together,

and laid in one direction, to form spaces and series of similar bands interlaid in alternately parallel and crossing layers therewith to form a ply fabric, and a fibrous binding means for the threads in each band, a

each band having a binding of rubber incorporated therewith andall bands cohering together and compressed to fill all spaces between said spaced bands.

In testimony whereof, I hereunto set myt hand this 14th day of October 1910. 4
