FlGURED DOUBLE PLUSH FABRIC.

SPECIFICATION forming part of Letters Patent No. 641,978, dated January 23, 1900.

Application filed April 3,1899. belial No. 711.523- (No model.)

To a/ZZ whont it nuty concern:

Be it known that I, HENRY LANGER, of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Figured Double Plush Fabric, of which the following is a full, clear, and exact description.

The object of the invention is to provide certain new and useful improvements in figured double plush fabricssuch as carpets, plushcs, velvets, &c.whereby various variegated effects of the ordinary figured fabrics can be produced in a very simple and economical manner Without the use of creels for the pile-threads and without requiring much, if any, skilled labor.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal section of the improved fabric, showing the two plush fabrics with the pile-threads uncut. Fig. 2 is a crosssectional elevation of the fabric. Fig. 3 is a longitudinal section of a modified form of the improvement with the filling forming part of the face of the ground of the fabric instead of the back, as shown in Fig. 1; and Fig. 4 is a like view of another modified form of the improvement with the special filling on the inside of the fabric.

In weaving the figured double plush fabric two fabrics A and A are formed and arranged opposite each other, with warps B and wefts C in the fabric A and warps B and wefts C in the fabric A to form the ground for the corresponding fabric. The fabrics A and A are further provided with pile-warps D D, respectively, and the fillings E E for said pile-warps D D. As shown in Fig. 1, the pile-warps D D are bound in by the wefts C, and the pile-warp threads extend during a given number of picks from one fabric to the other to form the pile D for the fabrics. The pile-warps D D are interwoven at the ground fabrics at places where no pile is formed, and

the said warps D D are beamed on a beam having a positive let-off motion, and in order to prevent any slack in the pile-warps in those places where no pile is formed when the fabric is woven I arrange the fabrics A and A a distance apart and select the fillings E and E of such size that when the fabric is woven the length of the pile D for a given number of picks corresponds exactly to the length of the pile-thread for the same number of picks in the corresponding fabric A or A. Thus, for instance, as shown in Fig. 1, the pile-warp thread extending from the fabric A to the fabric A and back again to the fabric A embraces four picks, and the length of this pile-thread corresponds to the length of the Warp-pile thread in the fabric A for the preceding four picks. I, however, do not limit myself to the exact number of picks, as the arrangement may be varied according to the desired length of the pile. (See Fig. 4.)

From the foregoing it will be seen that it is essential that a pile-thread from its departure from the ground to its return connection therewith spans a plurality of picks and is of a length corresponding to the pile-warp thread bound in in a number of picks equaling the number of the picks spanned.

From the foregoing it is evident that when the fabric is woven and the pile-warp is regularly let off from its beam at the usual intervals or speed then no slack whatever can take place, as the pile-warp threads are uniformly woven into two fabrics A and A, some of the pile-warp threads extending from one fabric to the other to form the pile. Now when the two fabrics are separated and the pile D is cut at the middle of the pile-threads extending from one fabric to the other then each fabric has a body and a figured plush on its face. It is understood that this separation of the two fabrics takes place in the same manner as in other double plush fabrics heretofore constructed.

It is expressly understood that the pile- Warp for my new Weave and the improved method of Weaving figured double plush is beamed in the ordinary manner on a beam which lets off at each beat of the lay a uniform length of all pile-Warp threads, and in such places in the fabric where plush is made the weaving is almost identical with that of weaving ordinary plush, and in such places of the fabric where plush should not appear the pile-warp threads are properly bound in the fabric without any slack for the reason above explained, so that there is always the same tension on the pile-warp.

The thickness of the special filling for the pile-warp varies in relative proportion to the length of the pile, and the length of the pile is in relative proportion to the special fillings, and according to their selection any required length of pile may be obtained.

At the points in the fabrics where the pilewarp threads pass from one fabric to the other the fillings E and E float on the back of the fabrics, as will be readily understood by reference to Fig. 1.

As the pile-warps D and D are bound in with the grounds of the fabrics and formed by the warps B and B and wefts O and C, it is evident that the filling-threads may be removed or drawn out to leave loops on the back of the fabric.

In the weave shown in Fig. 3 the fillings E E in the grounds are arranged on the inside of the fabrics A A instead of on the outside thereof, as illustrated in Fig. l; but

otherwise the weave is the same as above described. If desired, the special fillings may from its departure from the ground to its return connection therewith spanning a pinrality of picks and being of a length corresponding to the pile-warp thread bound in a number of picks equaling the number of picks spanned,substantially as shown and described.

2. A figured plush fabric, consisting of two opposite fabrics each composed of a warp and a weft for forming the ground, and pile-warps and pile-warp fillings for forming figured plush, the pile warps crossing alternately from one fabric to the other and spanning a plurality of picks in each fabric, the length of the crossed pile from its departure to its return connection being of a length corresponding to the pile-warp bound in in a number of picks equaling the number of picks spanned.

3. A figured plush fabric, consisting of two opposite fabrics each composed of a warp and a weft for forming the ground, and pile-warps and pile-warp fillings for forming figured plush, the pile warps crossing alternately from one fabric to the other and spanning a plurality of picks in each fabric, the length of the crossed pile from its departure to its return connection being of a length corresponding to the pile-warp bound in in a number of picks equaling the number of picks spanned, as specified.

4'. The herein-described method for forming figured double plush fabric, consisting in simultaneously weaving two opposite fabrics by interweavingv separate sets of warps and wefts to form the grounds for the separate fabrics, interweaving pile-warps and fillings with the said grounds, and crossing a portion of the pile-threads from one fabric to the other and connecting it thereto at the ground and then passing it back again to the ground of the first fabric and spanning a number of picks therein, the distance traversed by a pilewarp from its departure to its return corresponding to the length of the bound-in pilethread for a number of picks equal to the number of picks spanned by the pile-thread.
