My invention relates more especially to 7 that class of fabrics that are used for sheltering growing vegetation, more especially tobacco, and an object of my invention, among others, is to provide a fabric of this kind provided with means that shall enable it to be rapidly put in place whenever 1t frames are commonly arranged, en

field and supported b said posts,

tojs'ai wire as by means of- I not cord. This curing the fabric to shall have been displaced by extraneous forces, aswind and storm; and a further object of my invention isto provide a fabric of this class with means to limit the extent of tear or rupture caused from extraneous forces, as wind and storm.

Figure'2 is a face view of a'pieceof fabric illustrating one adaptation of my invention. Figure 3 is a view in section through the fabric illustrated in'Figure 2.

y In the use of fabric especially employed for covering tobacco fields for the purpose of sheltering and shadingthe tobaccoplants, ported posts 'disposed at intervals over 1: e' field and thefabric or clothislattached to wires extending inv different. directions across the the fabric being-secure fabric in use at'the present time provided with selvage edges through which the. fastening cords are passed in sethe wire frames. .Wind and storm. frequently places severe strains upon this fabric to such extent that it is torn from the frames,such tear commonly taking place just inside the selvage edge, and it is then a diflicult matter to again secure the fabric in place, for the owing to the factthat it'is not practical to make the fabric or cloth of sufficient strength to withstand the stress of all storms.

In carrying my invention into effect I do pro ose to strengthen the crosswise or filling t reads ator near the outenselvage in a manner the cloth at or near the outer edge, but I pro se to-so construct the fabric that the tearmg shall be localized and confined within certain bounds.

body 5 of the fabric. be attained, is illustrated in the.

attach the fabric to the wire frames,

reason that there is not enough strength in the body of the fabrie to-resist the strains,

to interfere with the tearing of- To this end I provide a fabric 5 of any ordinary weave or construction, which fabric may be produced of any desirable width and which is provided at its edge with a selvage 6 in a manner common heretofore produced. This selvage 6 will be" employed for securing the fabric to the wire. frames in the manner as heretofore practiced. When the cloth, by reason of excessive strains, shall become: torn, and usual at or near this selvage 6, I rovide a secondary selvage 7 located at asultable disto fabrics as istance from the outer selvage 6, that portion 8 of the fabric-between the two selvages being preferably formed The selvage 7 ispreferably located at such distance from the selvage 6 that when the fabric becomestorn between the two selvages, that one 7 may be made use of in place of the selvage 6 to rtet estretching of the fabric in use usually enabling it to be taken u to this extent. 1

While a fabric 'em odying a single selvage 7 at a redetermined distance from the the same as the main selva e 6 will answer my purpose to a very I satis actory extent, yet inla preferred form I provide two selvages, as shown in Figure .1, the second secondary selvage- 9 being located close this may be made" become torn between the vages. It is my purpose, use-of these secondary selvages to make a fold or tuck 10, as'shown in Figures 2 and 3 of the drawin secured for t e purpose of attaching the fabric in place become torn between the selvages.

- My invention contemplates a secondary selvage, and by this I mean a structure not at the outer edge of-the fabric when the goods are new, but which structure, after certain wear and tear, most frequently by stretching and by storm resulting in the loss of the first oredge selvage, will leave this secondary selvage at the approximate edge of the fabric.

7 It is not practical for obvious reasons, to. make the cloth of sufiicicnt strength to resist the stress of all storms, some to the secondary selvage 7, and

two secondary selonl tears the cloth but breaks the wires an osts that support them. Recognizing the act that there are times and conditions under which use of should the fabric 7 however, in the' to which the cords may be of. which 1 are accompanied by, hail andwind that not llO' the cloth is liableto be torn- I do not propose to interfere with thecommon tearing of the cloth at or near the selvage, as tears at this place are more convenient for mending than at any other, place 7 in the fabric. I do, however, propose to localize such tears within certain. definite limits of the selvage by providing the secondary selvage or selvages, as hereinbefore describe'd,'located at a certain distance from the edge selvage.

I claim- 1. A piece of awning fabric for protecting; vegetation and comprising, abody, a marginal selvage, a narrow strip adjoining said selvage and of the same texture and strength as the body, and a secondary selvage located between said body and said narrow strip and adjacent the marginal selv wage to prevent tearing of the narrow strip from extending into the body, said narrow strip localizing tearing strains between the two selvages; 1

2. A piece of awning fabric for I rotecting vegetation and comprising a ody, a plurality of adjacently positioned selvage moaese strips at the margin of the body, said rselvage strips being separated by narrow strips of the same texture andstrength as the body, whereby tearing strains are localized to a zone between the selvage strips with than said body to serve as a suspensionmeans for said awning, a secondary selvage Woven into the body of the fabric in narrowly spaced relation to the selvage edge to serve as a secondary means for suspen- Sion of the fabric when the selvage edge becomes useless, and a localizing strip located between saidse'lvages and ofsubstantially the same strength and texture as the body of the fabric to localize tearing strains between said selvages, and the secondary selvage preventing such tearing strains from extending into the body of the fabric.
