LAMINATED GOHESIVE INTERWOUND FABRIC BAND.

Specification of Letters Patent. Patented May 11, 192() Application filed December 8, 1916, Serial No. 135,802. Renewed October 24, 1919. SeriaLNo. 333,110.

To all whom it may concern:

Be it known that I, LAWRENCE A. SUBERs, a citizen of the United States, and resident of Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and .useful Improvements in Laminated Cohesive Interwound Fabric Bands, 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 an improved form of fabric band for use in constructing hose or analogous tubing, belting, or for incorporating in the casing or tube of a pneumatic tire, particularly in constructing tubing to resist comparatively high internal pressure.

The invention comprises an improvement upon Letters Patent No. 1,017,271, granted February 13th, 1912, for a lammated-co hesive-interwound fabric band, and Letters Patent No. 1,136,292, granted April 20th, 1915, for reinforced laminated-cohesiveinterwound fabric band.

In the above referred to invention a fabric is formed first as a tube and then flattened into a band having selvage edges, and the band is composed of a predetermined number, of parallel spaced'yarn elements, laid in groups or series in parallel spaced rows, at a predetermined angle, the rows of one series being crossed by the rows of the other series, said series being laid alternately in opposite directions, the series of each outer lamination filling the spaces between parallel laminations of the inner series, so that when the laminations are flattened together, all interstices are filled, and the sides of the tube each comprise one complete layer. The flattened tubular bands thus constructed are afterward wound or laid to construct an adjustable laminated-cohesive-interwound' fabric therefrom, by means of a machine and substantially as described with modifications 1n the prior Patents Nos. 1,052,915, granted April 30, 1912; 1,132,639 granted March 23, 1915; No. 1,052,014 granted March 26, 1912; No. 1,152,63 1 granted March 23, 1915; 1,052,040, granted April 23, 1912, and others.

In the former applications for Letters Patent a flattened tubular band has been described, the walls of which were composed of one complete layer of laminated,

cohering, interwound fibrous yarn elements, with or without a central band or strip of adhesive elastic material or a central reinforcing strip.

This fiattened band was produced by means of a machine having a group of four reels alternately rotating in opposite directions about a central mandrel upon which the bands are formed, in the manner above described.

"The present invention comprises a tubular band constructed of two or more layers in which each layer has a predetermined number and strength of yarns or threads and which are laid in laminations at a predetermined angle, and the second or any succeeding layer may have either such a number of yarns in each parallel row or group, so as to cover the entire surface of the first laminated band or can have a predetermined number of yarns laid at a predetermined angle, that will only cover a portion of the surface of such constructed band which will thenhave a predetermined tensile strength and extensibility according to the number of layers, the number and strength of the yarns comprising such layers, and the angle of laminations as may be desired for any given strength and extensibility in the construction of products desired to be manufactured therefrom.

This band is formed progressively by means of a suitable central mandrel, a forming machine consisting of two or more groups of reels, each group of reels being such as shown in Patent No. 1,201,774, granted October 17th, 1916, and various other patents.

The first group of reels forms onecomplete layer of fabric, consisting ,of four series of spaced parallel rows of fibrous .yarn elements, each element comprising a predetermined number of yarns, and each series crossing adjacent series at a predetermined angle upon a suitable central mandrel and the second group of reels form a second layer formed in a manner similar to the first group of reels with the exception that the series composing the second or any succeeding layer may be laminated at different angles in the different layers and each parallel row of fibrous yarn elements in the series of the second or any succeeding layer may have such a predetermined number of yarns that it will only cover a portion of the surface of the band.

creased predetermined tensile strength and -predetermined extensibility. The tube thus formed is coated with an elastic adhesive and cohering substance and is thereafter collapsed into a flat flexible band which-is finally compressed and dried.

The improved band is illustrated in the accompanying drawing. Figure 1 is a plan view of the preferred form of my invention comprising outer and inner layers, a central or axial band, and additional bands intermediate of the layers; Fig. 2is an edge view of the same; Fig. 3 is an enlarged transverse section thereof.

In these views A represents a central or axial strip to which the fibrous yarn elements adhere. This central strip may consist of elastic cohering material or fabric coated with such elastic cohering material and preferably vulcanizable which will readily adhere to the coated fibrous yarn elements. B. B. represents the spaced fibrous yarn elements preferably formed of fine cotton threads embedded in preferably vulcanizable and elastic cohering material. Said fibrous yarn elements can be made of long or short staple cotton and be employed in the production of the band with good effect. C. C. are the spaced fibrous yarn elements laid or wound upon and crossing the elements B. B. at a predetermined angle and forming the second series or lamination. D. D. are the spaced fibrous yarn elements forming the third series or laminations and are arallel with the first wound elements B. The bands in the third lamination register with the spaces between said first wound elements. E. E. are the spaced fibrous yarn elements comprising the last lamination of the first layer, and are laid or wound parallel with the elements 0. C. These four series or lamination complete the first layer.

In the second layer F, F, are the parallel spaced fibrous yarn elements of the first series or lamination lai d or wound at a predetermined angle, G, G arethe'fibrous yarn elements of the second series or lamination crossin the first lamination F of the second ,layer, H are the fibrous yarn elements forming the third series or lamination of the second layer and are laid or wound parallel with each other and into the spaces left by the elements F, F. The fibrous yarn coated with such elastic cohering substance are interposed on between the layers L and L both sides of the band after the first group of reels have completed their laminations for the purpose of increasing the thickness and flexibility of the band, and

additional bands or strips can be similarly inclosed between the layers at the edges at N. N. if desired.

It is obvious that, in constructing a band similar tothe one described in my invention, more than two layers of fibrous yarn elements may be employed, and the angle at which the second or any succeeding layer is applied need not be laid at the same angle as the first layer, and it is further obvious that in coating the fibrous elements with an elastic cohering and adhesive substance that either vulcanizable compounds such as rulr ber or other adhesive compounds may be applied which will give the desired result, without departing from the spirit of my invention or scope of my claim.

Having, described the invention what I claim as new and desire Patent is A fabric band including a central axial band shaped core in which vulcanizable material is incorporated, a layer thereon inclosing the same formed of laminated spaced parallel series of fibrous bands cohering in a vulcanizable material, and an outer layer of laminated cohering spaced parallel bands superimposed upon the first named series, and a flattened member in which vulcanizable material is incorporated, inter,- posed between said outer and inner layers.

In testimony whereof, I hereunto set my hand-this 17th day of November, 1916.

LAWRENCE A. SUBERS.
