H. l. DIAMOND FABRIC Filed Oct. 22. 1926 Patented Aug. 12, ieee UNITED sTAras arri-Nif'"ori-ica HARRY I. DIAMOND, F ATLANTA, GEORGIA Y VFannie Application ined october 22, 192e. sei-iai No. 143,441."

This invention relates to a novel and improved fabricwhich may have a variety of i The invention will be best understood from the following description when read in connection with the accompanying drawing in which I have shown a selected embodiment of my invention and wherein:

Y Figure 1 isa plan view of a piece of fabric constructed according to my invention., Figure 2 is a section through a plurality of plies of rubberized fabric superimposed upon one another. v

Figure Bis a view similar to Figure 2 but showing the plies after pressure has been applied thereto.

My invention comprises a fabric in which the threads running in one direction, for eX- ample the warp threads, are made of a plurality of sizes. The number of different sizes may vary as may be found desirablefbut, for the purposes of illustration, I 'have shown the threads running in one direction as made of two diierent sizes yof cord. When my fabric is to be employed in a structure subjected to bending and flexing, it is preferable to have the warp threads made of different sizes for reasons which will be eX- plained later.

In Figure 1 I have shown the warp threads as comprising cords 1 of relatively large size and alternating therewith are smaller warp threads 2 made of a smaller size of cord. The weft threads 3 may be made of any suitablek size and number. These threads are made of cords of suihcient size and number to hold together the warp threads, because in most structures in which my fabric is employed `there is little, if any, stress scope -of my invention.

which has to be taken by the weft threads. While have shown large and small cords forming the warp threads as alternating, it is obvious that this arrangement may be va-y ried somewhat without departing from the K However, Ihave found the construction shown to be very satisfactory. i

l/Vhen a ply of fabric, such as shownin Figure 1, is coated withrrubber, it will be60 apparent that an additional amount of the rubber will be contained in the coated fabl ric because of thefact that the smaller cords 2 provide spaces 4f iii the nature ply is superimposed on the other as shown in Figure 2, it will be apparent that the pockets 4 which are filled with rubber form ,cushioning means to receive the cords 1 on the adjoining ply of fabric. The result is al structure 4somewhat as shown in F gure 3,

` it being understood that this figure is greatly magnified. When the plies -of fabric are placed one on the other, the larger cords 1 automatically find the pockets 4 between the @t5 larger cords on the adjoining ply and the result will be that a bond is formed between the plies which will prevent sidewise slipping.' Moreover, the additional amount of rubber made possible by the pockets 4 is dis- SO Vposed between the cords of the respective plies and, therefore, these cords are kept out of contact with each other and supported by each other by aV greater amount of rubber than is possible when employing prior `art C fabrics.

When a. structure madeup of one or more plies of rubberized fabric and lc'aonstructed according to my invention is liexed longitudinally, it will be seen that the flexibility is t increased first by providing the smaller cords and secondly by the additional amount of rubber which will receivev the cordsv on adjacent plies. Even though the fabric plies are not placed in position so that a large @-35 cord will be directly above a. smaller cord on another ply, nevertheless, the plies will automatically come to this position `as will be obvious to those skilled in the art.

It will be apparent to those skilled iii the 3100 of pockets between the larger cords 1. Then, when one "65 l art that various changes may be made Without departing' from the scope of my invention and I therefore do not intend to limit myself except by the appended claim.

5 I claim:

In combination, a plurality of plies of fabrio superposred on one another, eachply comprisng a rubberized fabric having `adjacent longitudinal cords of derent size, the cords 10 of one ly being positioned over the cords of a di erent size in the adjacent ply.

In testimony whereof, I have alxed my signature to this speccaton.
