'Toall 'whom t may concern.

Be it known that I, THOMAS BReNsoN, a

i citizen of the United States, residing in Philadelphia, in the county of Philadelphia and` State of' Pennsylvania, have invented certain new and useful Improvements in Reinforcing Fabric Strips for Tires, whereof the following is a specification, reference being had to the accompanying drawings.

The invention relates more particularly `to a fabric strip for tires which includes a series of substantially straight parallel cords extending lengthwise of the strip.

An object of the invention is to provide a strip wherein the parallel cords extending lengthwise thereof and forming the body portion of the strip are connected by threads which are so arranged that the strip may be cut lengthwise without disintegrating said cut portions.

A furtherobject of the invention is to provide a reinforcingl fabric strip of the above character .wherein the connecting threads include rows of enchained loops extending lengthwise of'the strip, which enchained loops are suiiiciently' elastic to permit the cords when under tension to lie straight. y

A still further Vobject of the. invention is to provide a.reinforcing fabric of the above character wherein the connecting threads include separated rows of enchained thread loops and-connecting binding threads which join the 'rows of loops.

These and other objects will in part be obvious and will in part be hereinafter more y fully disclosed.

In the drawings, Figure I, is an enlarged plan view of a fabric having my improvements embodied therein.

Fig. II, is a similar view but showing aA slightly modified form of arrangement of the connecting threads which sustain the,

cords are not only liable to pile one on topof the other, but the strips must be made in the exact width in which they areto be used.' The present invention is directed to the improved way of joining the cords 'wherein the cords are held from pilin one ontop of the other, and whereby the abrio integrating the cut portions. I have acconiplished this connecting of the cords in the present .embodiment of the invention by using a series =of rows of separately enchained thread loops extending longitudinally of the strip and 'connecting these en chained thread loops by binding threads, said enhained loops and binding threads being disposed between and about the'coids so as to join the saine to form the fabric strips.. v

Referring more'in detail to the drawings, I have shown my improved reinforcing fabric strip as consisting of a series of cords 1, which extend substantially straight and parallel with each other and lengthwise of the strip,-which is to 'be embodied in the tire. In the form of the invention shown in Fig. I, I- haveprovided a series of rows of enchained thread loops 2. These rows of loops are each separately enchained and extend lengthwise yof thev fabric strip. In

other words, the enchained series 2, consists next loop 4, and this loop. 4, encircles the base of the loop 5.V The loop 3, is brought from underneath the cord 1, at one side thereof, and extends across the cord. The loop, 4, is brought from underneath the opposite side ofthe same cord and extends across the same, and the loop 5, isagain brought y fromnnder the same side of the cord 1, as

the loop 3. Thus it will be seen that these enchained loops will completely envelop one of the cords. Two binding` threads are used.

These 'binding threads are indicated at 6,

and 7 and pass through one or more of the enchained loops extending about one of the cords, and then across to the next row of enchained loops extending about another cord. Preferably-between the binding threads 7, and 8, isz a cord 1, so that alternate cords are enveloped by the enchained loops, and

and these alternate cords extend between the lot binding threads.

strip may be cut longitudinally without disi Itwill readily be seen that if this fabric strip formed as shown in Fig. I, is put under tension, the enchained loops being elastic will yield suiiici'ent so as to allow the cords to lie each other and prevent said cords from pil? ing one on top of the other. By cutting the binding threads between two of the cords7 Athe strips may be cut longitudinally and the enehained loops form a selvage edge which prevents thecut portions from disintegratout when the strip ing. Of course, it is understood that the cord held only by the bipding threads would drop is cut. This fabric strip may be made in any desired width most convenient to manufacture, and then may be out to any desired width for use, depending upon the size of the' tire into which it is to be embodied. i

In Fig. II, of the drawing, I have shown a slightly modified form of the invention. The enohained loops indicated at 8, are similar in construction tothe enehained thread loops indicated at 2,`in Fig. I, with the exception that these enchained thread loops do not envelop the cord. The binding threads indicated at 9, and 10, are arranged slightly different from that shown in Fig. I. I have also shown two cords in this modification of the invention between two adjacent rows of enehained thread loops 8. thread 9,v passes over the two cords, while the binding thread 10, passes underneath the same. Thus the cords are held through the combined action of the enehained loops and y the cords may be made without departing' the binding threads. v

It will be obvious that other n'iodifications in the general arrangement of the enchained thread loops and binding threads and also from the spirit of the invention? The essential feature consists in connecting the threads for sustaining the cords so that the cords may be placed under tension and lie straight without bending, and so that the fabric strip may be Acut longitudinally without disintegrating the eut sections of the strip.

ltween the adjacent rows of enehained loops,

The binding necting said enehained thread loops, said enchained thread loops and. binding threads being dlsposed so as to connect and hold said cords, whereby said strip may be cut in a lengthwise direction between alternate binding threads.

2. A reinforced fabric strip for tires, comprising a series of straight parallel cords, extending lengthwise of the strip; a series of separately enehained rows of thread loops extending lengthwise of the strip; and binding threads extending back and forth besaid enchaincd. loops, and binding threads being disposed so as toconnectand hold said cords.

3. A reinforced fabric strip for tires, oomprisin g a series of straight parallel cords extending lengthwise of the' strip; a series of separately enehained rows of thread loops each disposed so as to envelop one of said cords, and eonnectingfbinding threads joining adjacent rows of enehained loops.

4. A. reinforced fabric strip for tires, com; prising a series of straight parallel cords eX- tending lengthwise of the strip; a series of separately enohained rows of thread loops extending lengthwise of the strip, said enchained thread loops being disposed so as to envelop alternate cords and binding threads joining rows of enchained loops, said binding threads being disposed so as to embrace and hold the intermediate cords between the rows of cnchained thread loops.

In testimony whereof I have `hereunto signed my name at Philadelphia, Pennsylvania, this eighth day of March, 1918.
