Specification of Letters Patent.

- Application filed July 21, 1914. Serial No. 852,173.

To all 'whom it may concern:

Be it known that I, LAWRENCE A. SUBERS, a citizen of the United States, and resident of East Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in a Laminated, Cohesive, Interwound, Bonded Fabric, 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.

The objects of the invention are to provide a fabric of the type described in Letters Patent granted to Lawrence A. Subers upon March 26, 1912, and bearing Number 1,021,014.

This fabric has been described in the aforesaid Letters Patent as a laminated, cohering, interwound fabric, constructed upon a cylindrical mandrel, from series of spirally wound fabric bands, which cross each other at predetermined angles.

In the previously described fabric, the bands which comprise the fabric portion thereof are first made in tubular form and afterward flattened and are constructed from series of fibrous elements or flexible members which are coated with a liquid adhesive such as rubber during the process of construction of the band.

In my prior Patent No. 1,187,564, a flattened band of the same type as the preceding is described, in which in addition to the liquid adhesive with which the fibrous elements are coated during the construction of the band, a continuous layer of solid vulcanizable adhesive is interposed between the fibrous elements.

In this manner the amount of adhesive incorporated in the body of the band is greatly increased, and the fibrous elements in the sides of the flattened band willadhere together more strongly when the additional amount of adhesive is thus introduced, andwill not readily tear apart when the band is placed under tension or strain. ,Also when the bands are placed under a preliminary tension to control the amount of subsequent extensibility thereof, this increased amount of adhesion will prevent any tendency of the bands to resume the tubular form.

To a complete understanding of the fabric the construction of the fabric bands must be understood.

These fabric bands are constructed from a plurality of series of parallel spaced,'in-

terwound, cohering fibrous elements, one

series crossing the other at a predetermined angle and coated with liquid adhesive. Between the series of fibrous elements is interposed a continuous layer (which may be bands) of solid, which fills all openings between the fibrous elements and appears upon the surface in regularly positioned diamond shaped spaces.

From such bands the laminated, cohering, interwound fabric is constructed, and the exposed diamond shaped portions of the adhesive in the crossing bands cohere together, thus binding the elements of the fabric more closely together and incorporating in the fabric a greatly increased amount of solid adhesive, and producing a bonded fabric which is possessed of a high resiliency, strength, and durability, and thereby greatly increasing its efiiciency for general use.

This fabric, although a laminated structure, possesses no place of cleavage after it has been vulcanized, but is bound together into a homogeneous, unitary mass. The invention is hereinafter further described, shown in the accompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is an isometric view showing the manner. of constructing the fabric from series of fabric bands; Fig. 2 is a plan view of a tube showing portions of each series of bands broken away; Fig. 3 is a plan view of one of the fabric bands showing the diamond shaped spaces formed by the solid adhesive in its surface; Fig. 4 is a transverse section of one of the fabric bands, enlarged, and showing a rubber layer interposed between the yarn elements thereof; Fig. 5 is a similar enlarged section showing an added central band of rubber or other adhesive inclosed between the sides of the flattened band; Fig. 6 is a transverse section (enlarged) through line 66 Fig. 2, showing the layers of solid adhesive incorporated in the several fabric bands; Fig. 7 is a similar section showing fabric bands having a central band of rubber incorporated therein in addition to the other layers of solid adhesive; Fig. 8 is a longitudinal section on line 8-8 Fig. 6.

In these drawings A, A, are fabric bands formed originally upon a mandrel by wind vulcanizable adhesive,

2. In a laminated fabric, a series of spaced, parallel, cohering and interwound, laminated, fabric bands, each band composed of series of parallel, cohering, interwound flexible, fibrous elements, one spaced series of elements crossing another spaced series of elements at a predetermined angle, providing spaced diamond shaped openings interspersed throughout the bands, some of said diamond shaped openings being positioned in the outer surface of each band, and a solid adhesive filling all said openings, the adhesive filling the said surface openings in one band cohering to the adhesive filling the surface'openings in adjacent bands and serving as a bond to unite the bands into a unitary structure.

3. In a laminated fabric, a series of spaced, parallel, cohering, interwound, laminated fabric bands, each band composed in turn of cross series, of spaced, parallel,

- cohering interwound fabric elements, the

elements in each individual band being arranged in layers, and crossing each other at an angle, and a layer of solid adhe sive material interposed between adjacent layers of fibrous elements, said adhesive layer separating and cushioning'said fibrous elements at crossing points and being exposed along the exterior'side of each band in spaced positions, the solid adhesive upon the exterior sides of adjoining bands cohering in said fabric and serving as a bond to unite said bands into a unitary structure.

4. As an article of manufacture, a laminated fabric comprising-a series of laminated, spaced, interwound, fabric bands, each of said bands comprising spaced, parallel, flexible elements interwound in layers,

the elements in one layer crossing those of another, and in which bands fluid adhesive is incorporated to cause the fibrous elements 1n said bands to cohere, said bands having interspersed and surface openings therein,-

said openings filled with a solid adhesive and said solid adhesive also forming a cushfabric bands, each band composed of crossed series of spaced, parallel, ,coherlng, interwound fibrous elements, between the several series of which a layer of solid adhesive material is interposed, and which is exposed upon the exterior sides thereof in spaced positions, said exposed portions of the adhesive material being of a thickness substantially equal to the thickness of the surface portions of fabric on each side thereof.

6. In a laminated fabric, a series of laminated, cohering, interwound bands, each band provided with exterior and interspersed openings containing solid adhesive of material thickness compared with the thickness of the fabric layers adjacent thereto, the adhesive in the exterior openings in adjoining bands cohering to unite said bands into a unitaryv structure.

In testimony whereof, I hereunto set my hand this eighteenth day'of July, 1914.
