lines or rows. Such a web has several objec-` tionable features in that at the more or less open portions where ventilation is permitted,

the web is relatively weak. Also, while web of this character is flexible it is more or less unevenly iiexble and has a tendency on account of the open portion of the web being continuous, to have a hinging action at the portion where the Ventilating rows occur and to have too much stiffness at other portions. In other words, the usual ventilated web,

" heretofore known, will have a number of hinge lines and be relatively stiff and iniiexible between those lines.

One object of this invention is the provision of a well ventilated web for use in the manufacture of corsets and like garments, which will at the same time be strong and durable and in which weakened lines will be absent.

Another object of the invention is to provide a ventilated web of this character which will be substantially evenly iexible throughout, and which-will not have a tendency to fold or hinge along certain lines.

Another object of the invention is the provision of a web which shall have provision for ventilation, and which shall be strong and durable and at the same time evenly iiexible.

Another object of the invention is the provision of a ventilated web susceptible of being made in various ways in which the ventilated portions form ornamental patterns on the face of the web.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings:

Fig. 1 is a more or less diagrammatic view of the upper surface of one unit of my improved web greatly enlarged;

Fig. 2 is a similar view of the reverse side of a Ventilating or open portion of the web; Fig. 3 is a diagrammatic sectional view of two adjacent rportions of the web, one of which is relatively more porous than the v other;

Fig. 4 is a top elevational View of a portion of the web, showing the pattern or appearance when woven as shown in Fig. l;

Fig. 5 is a view similar to Fig. 4, showing a web of somewhat modified appearance.

I have chosen to illustrate and describe as a preferred embodiment of my invention, a.

webbing which may advantageously be made in width from 3 to 16, so that it may be used i'n relativel large pieces to constitute the major part of, form of narrow strips cut across the width, or in the form of gores. A width of 12 may be considered as a typical and popular width. The web ismade up of covered rubber warp cords, illing threads and textile warp threads. Some of thelatter threads perform a direct binding action, and others perform both a direct binding and a leno 'binding action.

The web may, for the purposes of description, be considered as made up` of a number of units which are repeated over andv over throughout its length and width, one of which units is shown in Fig. 1 of the drawings. Aside from a number of these units, a piece of the web will preferably have selvage edges, but as these edges may be of any usual character the are not shown, nor will they be described erein. A border may also be provided adjacent the selvage edge between said selvage and the body ofthe web.

In one unit of the preferred form of my invention shown in the drawings, there are a number of covered rubber warp cords extending longitudinally in substantially parallel relation. In the unit shown, there are seven of such cords A, B, C, D, E, F and G. Each of these cords preferably contains Aa thread of rubber, probably #36 or #40 in size, and is provided with a rst coveringofv four cotton threads wound helically in garments or be used in the parallel relation. It is also provided with a second covering of a single thread wound in the opposite direction 'constituting an open helix. These rubber cords are spaced apart to permit the weavingtherebetween of textile warp threads, and as will be pointed out, the spacing between the various rubber cords is not entirely uniform. In the web shown, nine reed dent spaces are used for the seven cords. The cord A passes through the first dent space, the second dent space is empty, the cord B passes through the third dent space, C through the fourth dent space, the fifth dent space is empty, the remaining 'cords passing in order through the sixth, seventh, eighth and ninth dent spaces. In this manner, the spaces between the cords A and B, and

y the cords C and D, are initially somewhat forty filling picks.

greater. than the other spaces between the cords. As the spaces between these cords are employed in the ventilated portions of the web, this results in the web being somewhat more open and porous than if the spacing were entirely uniform.

. It will, of course, be understood that the nal position and spacing of' the cords is de-J termined to some extent, by the amount of textile warp material between the cords. For instance, the cords D and E will be closer in the finished web than E and F, for the reason that there are but two warp Icords in the former space and tive in the latter.

In length, the unit of the web shown in the drawing, contains forty picks of filling which are numbered l to 40, respectively. The filling picks are arranged in groups of four, #l to #4, #5 to #8, #9 to #12, etc., it being understood that this arrangement of the four picks of a group is repeated throughout the length of the web. I will, therefore, describe the manner in which picks #l to #4 cross the rubber cords, and it will be understood that #5 crosses the cords in the same manner as #1, #6 the same as #2, #7 the same as #3, #Sthe same as #4, #9 the same as #1 and #5, and so on throughout the series of the Referring to the drawing, it willbe seen that the first filling pick crosses over and above all of the rubber cords and may properly be called an upper iilling pick, the second or #2 pick crosses above the cords A, B, C and D, and then passes to the back of the web to cross below the cords E, F and G. It then rises to the surface again to cross above the cord AA of the next unit.` #3 filling pick crosses below the cords A, B, C and D, and then rises to the face of the web to cross above the cords E, F and G, and then passes to the back of the web to cross below the cord AA of the adjacent unit, while #4 filling pick passes below all of the rubber cords.

Beginning at the left-handrside of the drawing, it will be apparent that in the upper left-hand corner are shown two highly porous or ventilated portions of the web V and V', while below these portions are portions P and P of relatively less porosity but at the same time being porous to some extent. 'Io the right of that part of the web just described, are portions H and H', which are relatively dense and non-porous. The manner of weaving the web so as to produce the novel and desirable features heretofore described, will now be explained.

It will be noted that at the left of the first covered rubber cord A, is a textile warp thread L1, which acts as a direct binder for a part of its length through the web and as a leno binder at the ventilated portions of the web. Asa direct binder, this warp thread is woven two up and twov down, passing over the upper filling picks and under the lower filling picks. To the right of the cord B is another such warp thread L2, while two likel threads L3 and L2 are disposed to the left and right respectively of the rubber cords C and D. A fifth of said threads, L5, appears to the left of the last rubber cord AA, but this thread properly belongs to the adjacent unit.

l To the right of the rubber cord A is a binder warp thread which may be termed a standard binder, as this passes through the web, two up and two down. When, however, the leno warp L1 and the standard warp Sl reach the ventilated portion of the web, the thread L1 acts as a leno binder, as shown in Fig. 2, and is brought under the cord A and the standard binder S1 so as to catch the latter with the cooperation of the two lower filling picks 1 9 and 20 and bind it closely to the rubber cords. The standard binder warp S2 is woven similarly to the thread S1, as j ust described, and cooperates in like manner with the leno warp L2. It will be seen, therefore, that the binders S1 and S2 are bound tightly against the sides of the adjacent covered rubber warp cords, so as to leave the Ventilating spaces quite free and open, these spaces being obstructed only by the passing of the upper and lower lling picks in a somewhat loose manner.

Between the rubber cords C and D are two standard binder threads S3 and S4 woven in a manner similar to S1 or S2,l and cooperating with the leno warps L3 and L4. At the right of the cord AA is another similar binder S5 which, however, properly belongs to the adjacent unit.

Between the ventilated portions is a por-` tion of relatively less porosity lying between the rubber cords B and C. At this portion of the web, two binder warps B1 and B2 are disposed between the leno warps L2 and L3. These binder warps, like the leno binders and the standard binders, also are woven two up and two down. They are woven, however, in staggered relation to each other, each passing over one upper and one lower filling pick and then under one upper and on'e lower filling pick. Being in staggered relation they cross when passing from one face of the web to the other, one rising to the surface of the web when the other passes to the back. Similar binder warps B1, B, B's and B6 'are disosed between the cords D and E, E and F, and G, G and AA, and it will be noted that each of these threads is staggered with relation to the nearest adjacent like thread of this group, but all are woven through in a similar fashion. y

In the relatively dense portion of the web in each of the spaces between the cords E and F and F and G, are disposed four figuring warp threads, two on each side of the binder warps B1 and B5. These figuring warp threads which I have designated F1 to F8 inclusive, are woven three over and one under, the threads F1 to F4 inclusive passing under the filling picks 2, 6, 10, etc., and over the other picks, and are all woven in parallel relation, that is, pass under and over the same picks in the same way.- The figurmg warps F" andFa inclusive, while woven three over and one under, are staggered with relation to the warps 'F1 to F4, so that they pass under the filling picks 4, 8, 12, A16, etc., and these threads, Fs to F8, are also in parallel relation in the web, in that they cross under and over the same filling threads.

I have now described a preferred form of Weaving all of the threads in a unit of my 1mproved web, but it will beunderstood that I do not limit myself to the exact weave described..

It will be apparent from an inspection of the diagrammatic view of Fig. 3 that the ventilated portions V and V1 of the web are highly porous so that the air can readily pass through the space between the rubber cords and between the upper and lower filling picks, as shown by the arrows. As also shown by the lower portion of Fig. '3, the portions P and P1 will be relatively less porous, as the space between the rubber cords will be obstructed not o`n1y-by the fillingpicks but also'by the standard warps S1 and S2. This portion of the webwill, however, be much ess dense and more porous than the adjacent portion. of the web between the cords B and C, or that part of the web between the cords E and F, and F and f It will also be noted that at the ventilated portions of the web, the standard threads S1 and S2 are, by means of the leno binders, bound tightly against the sides of the rubber cords so that they are drawn as Afar as possible out of the space between these cords.

In'Fig. 4 of the drawing, I have shown in a conventional way, the a pearance or the attern of the web shown iagrammatically 1n Fig. 1'. Fig. 4 contains six of the units shown in Fig. 1, and it will, of course, be understood that these units are repeated throu hout the len h and width of the web.

In ig. 5 of the rawings, I have shown a slightly modified pattern which may readily be produced with my improved weave. In this figure, the ventilated portions instead of being arranged side by side are staggered so that they occur in diagonal rows across the we In either form, however, it will be observed that I have provided Ventilating portions or units which are discontinuous and which are arranged in rows longitudinally of the web, these Ventilating portions being portions of great porosity and being separated by portions of less porosity. Between these ro\ws are strong and dense portions, so that the web as a Whole will be relatively strong and will, at the same time, be evenly flexible throughout. Each unit of the web contains a relatively less porous and a relatively porous portion in longitudinal alignment, and a non-porous portion at the side of the porous and the less porous portions.

While I have shown and describedia preferred embodiment of my invention, it is understood that it is not to be limited to all of the details shown, but is capableof modification and-variation within the spirit of the invention and within the scope of the appended claims.

What I claim is:

1. Elastic web containing covered'rubber warp cords, and filling picks crossing said cords, warp threads crossing said filling p1cks between the cords, .said warpthreads being bound tightly against the adJacent cords for parts of their lengths to form portions of relatively great porosity, and left free from the adjacent cords for other parts of .their lengths there to form portions of relatively less porosity.

2. Elastic web containing covered rubber warp cords, and filling picks crossing said cords, warp threads crossing said filling picks between the cords, said warp threads having alternate lengths thereof bound closely against the adjacent rubber cords and left Afree to space themselves between such cords respectively, so as to form portionsof relatively reat and relatively less poros1ty.

`3. E astic web containing covered rubber wa-rp cords, filling picks crossing said cords,

and textile warp threads between said cords, 4

and leno warp threads each'of which acts alternately as a direct binder for a plurality of filling picks, and as a leno binder to'bind a plurxilit-y of filling picks and another warp thread to the covered rubber warp cords.

4. Elastic web containing covered rubber Warp cords, filling picks' crossing said cords, and textile warp threads between said cords, and leno warp threads each of which acts alternately as a direct binder for a plurallty of filling picks and as a leno binder to'draw another warp thread-against and to the back
