Same, of which the following description,"

in connection with the accompanying drawmg, a specification, like characters on the drawing representing like parts.

This invention relates to pile fabrics and method of making the same and has for its object to provide a novel pile fabric which has the appearance of the fur of an animal having both long and short hair. This object is accomplished by making my improved pile fabric with both relatively long and relatively short pile, the relatively long and relatively. short pile being distributed over the entire surface of the fabric. Some orall of the relatively shortpile may be made from pile warp ferent in color from that from which the relatively long pile is made, and when this is done, the elfect will be that of a fur having both long and short hair in which the short hair is of a diflerent color from the long hair. P

In making my improvedfabric, I first form-the pile fabric with pile loops, certain of which are cut to form the short pile and others of which. are cut for the purpose of forming the relatively long pile. The long pile is formed by pulling out the uncut loops which are adjacent to some of the cut loops thereby withdrawing from the body of the fabric one of the cut,ends of each of said out loops.

In order to give an understanding of my invention, 1 have illustrated in the drawing some diagrammatic views which show both the/character of the fabric and the steps of making the same.

Figure 1 is a plan view showing diagramnlatically'the first steps of formlng a pile fabric in accordance with my invention;

Figs. 2, 3 and 4: are (perspective diagrammatic views showing iflerent steps in the process. V 7

The fabric herein shown is made up by interweaving body warp threads 1, pile warp threads 2 and 3, and filling 'threa s 4. In weaving the fabric, the pile warp threads 2 and 3 are manipulated by any suitable means so as to produce pile loops therein, these pile loops being bound into the fabthreads which are dif- ,a relatively short pile.

This gives to the fabric the of a fur ric by the filling threads 4 and body warp threads 1.

In weaving the fabric certain of the pile warps, to w1t, those indicated at 2, are manipulated in such a way that each Warp has pile loops formed therein in pairs, the loops of each pair being indicated at 9 and 10.

Theyloops

9 and 10 of each pair are preferably closely adjacent to each other v and are separated by a single filling thread a only, while the pairs of loops formed from any individual pile. warp thread will be separated considerably from each other so that the portion of the pile warp thread between the pairs of loops therein will be bound into the fabric by several filling threads c Certain of the other pile warp threads, for instance, those indicated by 3, will be so manipulated as to form pile loops 11 therein, preferably in regular order.

After the pile loops have been thus formed, the loops 11 formed from the pile Warp threads 3 are all cut, thus producing The pile loops 10 of each pair of pile loops formed from the pile warp threads 2 are also cut, of each pair remaining uncut. loop 10 of any pair of loops has been cut, then the loop 9 of said pair is drawn outwardly with the result that the cut end 12 the loop 9 After the of the loop 10 will be withdrawn from the face of the fabric thereby to produce a long pile 13 which has a length equal to the'coinbined length of the leg 12 of the loop 10 and the two legs14 of the loop 9. When the fabric is beaten up the pile face thereof will present both the lon pile 13 formed from the pile warp threads 2 and the short pile 15 formed from the pile warp threads 3, and these warp threads may lee-so disposedv in the fabric that the relatively long pile 13 and relatively short pile 15 will be inter-' mixed throughout the face of the fabric. a pearance of fur which has both long an short hair. The pile warp threads 3 may be of a darker color than the pile warp threads 2, in which case the pile fabric presents the appearance aving both long and short hair in which the short hair has a the long hair.

This operation of forming the pile 100 s, cutting certain loops and drawing out 1; e uncut loops may be performed in various ways without departing from the invention, but the invention is such that it can be darker color than advantageously practised in connection with the operations of a pile Wire loom which uses both knife wires, such as shown at 5 in Fig. 1, and hook wires, such as shown at 6 in Fig. 1. The knife wires illustrated may have any usual construction and are provided at their ends with the cutting blades 7. The hook wires 6 are shaped at their ends to present the hook portions 8 by which the uncut loops are pulled out, as above described. In using these wires in a pile Wire loom for weaving my improved fabric and for carrying out my improved method, I propose to introduce the pile wires into the fabric in usual manner so that there will be two filling threads 4 between each two adjacent pile wires, and I also propose to introduce the wires in such order that the knife and hook wires will be alternately introduced, as shown in Fig. 1. The pile warp threads 2 are manipulated so that each thread 2 will be looped over two adjacent pile wires, thereby forming the pair of

loops

9 and 10. One loop of each pair will be formed over a knife wire 5 and the other over a hook wire 6. Each pile warp thread 3 is so manipulated that it is looped over the knife wires 5 so that all of the loops 11 are formed over knife wires. Thus in the weaving of the fabric, each knife wire as it is introduced will have loops 10 and 11 of both the pile warp threads 2 and 3 looped thereover, while the hook pile wires 6 will only have the loops 9 of the pile warp threads 2 looped thereover. As each knife Wire 5 is withdrawn the blades '7 thereon will cut the loops 10 and 11 which are formed over said Wire. The cut loops 11 form the short pile 15 and each cut loop 10 forms two

short pile ends

12, 16. When the hook .wire 6 is withdrawn the hook 8 thereon will engage the loops 9 and will draw out said loops, thus withdrawing from the body of the fabric the pile ends 12 of the cut loops 10 thereby forming the long pile ends 13. Owing to the manner in which the long ile ends 13 are produced they will have a ength approximately equal to three times that of the short pile ends 16.

When the fabric is completed, the pile face thereof will present the long pile ends 13 and also the short pile ends 15 and 16. The

result is that the fabric when completed has the appearance of fur, especially if the pile warp threads are made of mohair or some similar material. By using dark-colored threads for the pile warp threads 3 and light-colored threads for the pile warp threads 2, the effect which is produced will be that of a fur having light-colored long hair and a dark-colored shorter hair.

I claim:

1'. A pile fabric of the type in which the pile is formed from pile warp threads,

characterized in that it has relatively shortvpile formed from certain predetermined pile warp threads and both relatively short and relatively long pile formed from each one of certain other predetermined pile warp threads.

2. The method of producing a pile fabric which consists in first weaving a pile fabric with pile loops formed in the pile warp threads, cutting all of the loops in certain of the warp threads and part of the loops in the other warp threads, and then drawing out the uncut loops whereby both long and short pile will be produced.

3. The method of producinga pile fabric of that type having both pile warp threads and body warpthreads which consists in forming in certain of the pile warp threads regularly spaced pile loops, forming in other warp threads pile loops arranged in pairs, cutting all of the regularly-spaced pile loops and one pile loop of each pair, and then drawing out the other pile loops of said pairs whereby both long and short pile are present.

4. The methodof weaving a pile fabric 011 a pile wire loom which consists in inserting knife wires and hook wires alternately in the shed, forming pile loops from certain of the pile warp threads over the knife wires only, forming pile loops from the remaining pile warp threads over both knife wires and hook wires, and then withdrawing said wires whereby the knifewires cut the loops formed thereover while the hook wires pull out the loops formed thereover thereby forming a long pile.

In testimony whereof, I have signed my name to this specification.
