lTo all whom. 'it may concern:

Be it knovm that I, EMIL J. VOGEL, a citizen of the United States, residing at Lawrence, in the-county of Essex, State of Massachusetts, have invented' certain new and useful Improvements in Fabrics; and I do here by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to woven fabrics of a thick and solid structure for use where a thinner fabric or several plies of a fabric would not answer the purpose.

The nature of the invention consists of a fabric composed of relativelv fine and hardtwisted warps, and large and loosely twisted wefts, tl e wefts being woven one on top of the other to the extent of the thickness of the cloth, by weaving up and down as well as forward.

'The structural characteristics of my im* proved fabric are clearly shown in the annexed drawings, forming a part of this speciiication, in view of which the mode of producing the fabric and its general structural characteristics throughout will first be described, and the invention then pointed out succinctly in the subjoined claims.

Of the said drawings-Figure 1 is a diagram showing a way of beginning the weaving of my improved fabric, as also some of its structural characteristics. Fig. 2 is a sectional view in the plane of the warps of the improved fabric. Fig. 3 isa plan of the same. Fig. 4 is a diagram showing a sectional view of a narrow fabric formed with a groove on one side and a tongue on the opposite side.

Similar numerals of reference designate similar parts, things, or features, as the case may be, wherever they occur."

n the reduction of my improved fabric I may emp o as many harness er sets of harness (not s own) as is practicable or necessary, according to the thickness, structure or design of the fabric that it is proposed to produce. For the purpose of this specifica tion, I show a fabric produced by the use of twelve harness which are operated in various ways, well known to those skilled in the art, to tie inthe warps in proper order in the fabric to effect its solidity as well as to produce varying designs on the face from the different colors of warps used. I also control the shuttle-boxes (not shown) so as to ell'ect the picks of weft in the proper order and plane.

For most purposes I employ relatively fine and hard-twisted warps, and in nearly all instances I use relatively quit-e large and loosely or softlv twisted wefts, one-half of the weft: being 'substantially but half of the dameter of the other half, and the large and small wefts being employed alternately.

In the drawings, i0 designates the large or thick wefts; 1], the smaller wefts; and, 12, the warps running o'n irregular lines through the fabric.

Turning again to Fig. 1 of the drawings, it will be noted that in beginning the weaving of a piece, in order that it may not fray'or fret, and to establish a base or abutment againstwhich to work to form a fully-thick fabric, I operate the harness so as to produce a common weave for two picks, one in advance of the other, as at 13, and then begin with three picks, one on top of the other, advancing forward two picks, as at 14', then with seven picks vertically, advancing two picks forward, as at 15, and then beginning the regular weave at. the point 16, for eleven picks vertically with alternate relativel thick and thin wefts advancing in le one ick in each vertical eleven. In ot er wor s, let it be supposed that I begin at the top a., at the line 16, where the harness are operated to form a shed for the pick of a large weft 10, .which Ais beaten up by the reed in the lay; then a shed is formed and a smaller weft 1 1 is picked through and beaten up in place below the first weft mentioned; then a third shed is formed and the larger weft is icked through, and-beaten up in place be ow the fine or smaller weft, and so on-a finer or smaller weft and a larger are woven in until eleven picks have been thus woven one below the other, terminating with a pick of a large weft 10, when a return operation upward is begun. The conuuencement of 'weaving upward,as at b, will be by a pick of a smaller weft 1 1 which will be beaten up theoretically in advance of the last weft 10 in weaving downward, and then a larger weft will be picked through' in advance of the smaller weft, lying next to the last in the downward weave, and so on until the top of the upward weave is reached when a small weftl will have been icked through and beaten up, so that while twenty-two picks will have been woven-eleven a, down and M w. h

eleven b, up-the length of the fabric will have been advanced but two picks, and the warp will have been operated accordingly, so as to tie in the divers wefts. l

With the description thus far given it will be seen that I can readily weave a fabric twice, three times or four times, or even more, as thick as that produced in accordance with the preieding explanc tion. In producing a thicker fabric I may employ additional harness with a proper draw, and, of 'course include more picks downward and upward proceeding forward but two picks in each downward and upward operation, as explained. Again, it. is obvious that the fabric will be thickened by increase in the size ofthe wcfts or warps, or both at the same time. By employing warps if different colors, it is obvious that by a proper draw of the warps, and a corresponding proper operation of the harness, figures of Varying design may be produced on the face of the fabric, as indicated in Fig. 3. In beating up the larger and smaller wefts, introduced alternately, the latter will be forced into position so 'as practically to form chinks between the larger warps, and so enhance the solidity of the fabric, though in the drawings, for the sake of clearness of illustration the wefts and ends are shown in normal form and in somewhat theoretical osition in order to completely expose the invention.

In the diagram, Fig. 1, there is shown to be an omission of wefts and warps at, 17, leaving a hollow if formed in the centerof the width of n. fabric, or a groove if formed at the edge. This is accomplished by the operation of the regular harness so that they will fail to cause the warps to tie in the wefcs along this line 17, though by the employment of four special harness the floating wefts can be tied in thereby so as not to leave any oating threads in the o ening or 'groove. If the wefts are allowe to float the can easily be .drawn out and cut off.

Fig. 4 I have shown how a ton ue c may be formed along one side of the cloth, so as to be entered in a groove d formed on the opposite edge as explained. In this way two or more strips of the fabric may be joined some what similar to lflooring boards and be stitched together or otherwise joined at their edges. It isobvious that two or more open spaces 17 may be formed in the body of the fabric as well as one. As before stated the number of harness may be increased from that shown in which case there will be an increase in the number of picks a and b vertically. W'ere I to use twenty-four sets of harness instead of twelve with the same size of wefts and warps, a fabric would be produced twice as thick as that made by twelve sets of harness and a correspondingly increased number of warps.

What is claimed is 1. A fabric consisting of wefts and warps comprising two set-s of wefts disposed in vertical order from top-to bottom of the fabric and of'relatively uite thick and soft twist each alternate we t being of but substantially half the thickness of the other wefts' in each pick forward in the construction of the fabric, the wefts being tied in by the sheds formed by the various warps from the top to the bottom of the fabric.

2. A fabric consisting of Wefts and warps comprising a series of wefts of quite thick and soft twist woven in vertical order each alternate weft being but' halt` 'the thickness of the other weft in each ick forward in the construction of the fabrlc, the wefts being tied in b regularly formed sheds in the war the simi ar wefts being beaten into the chinliis between the larger wefts and warps.

3. A thick woven fabric' comprising a series of fine hard twisted warps, a series of soit twisted wefts, and a second series of larger soft twisted Wefts, the wcfts being dis osed alternately and vertically in each pic forward in the formation of the fabric.

In testimony whereo'f, I afiix my signature, in presence of two witnesses.
