WOVEN PILE FABRIC.

Specication of Letters Patent.

Patented May t8, 19115.

Application filed September 10, 1914. Serial N o. 861,131.

T0 all whom t may concern Be it known that GEORGE CROSSLAND, a citizen of the AUnited States, residing at `Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Woven Pile Fabric, of which the following is a specification.

rThis invention relates to a woven pile fabric, and particularly to a type of such fabric which may be advantageously utiliZed as a carpet fabric.

This invention is in the nature of an improvement upon the pile fabric described and claimed in Letters Patent No. 1,038,532, issued to me September 17, 1912. In that patent T have shown a fabric in which four picks of filling or wefts are inserted within each crossing of the binder warps, these wefts being distributed in three planes with two of the wefts in the faceof the fabric. The Studer warps are near the face of the fabric, while all of the pile warps, except those forming the pattern at a given time, are carried at the back' of the fabric.

It is the object of my present invention to improve the fabric shown in my prior patent by increasing the number of threads of lilling or wefts within each crossing of the binder warps and by rearranging the pile and stuffer warps so that the pile warps shall lie next to the pile surface.

With this object in view, my invention contemplates the provision, in the .preferred form, of five picks of filling within each crossing of the binder warps, three of these picks lying upon the face of the fabric directly under the binder warp, and the other two picks lying at the back of the fabric and between the Studer andpile warps, respectively.

The preferred form of my invention is shown in the drawing which is a sectional view of a portion of pile fabric woven as hereinafter described .in this specication.

Referring to Vthe drawing, the binder -warps are indicated by the letter B, the

stuifer warps are indicated by the letter S, and the pile warps are indicated by the letter l), while the threads of filling or wefts are designated by the letter W. The fabric shown in the drawings is composed of two stuer warps, and two binder warps, with five wefts included within each crossing of the binder warps.

The pile warp forming the pattern at any particu-lar point is carried upward in two series of loops, each loop passing between two adjacent wefts and two loops and three wefts being included in the face of the fabric within a single crossing of the binder warps. There will, accordingly, be -one weft at the outside of each double row of pile loops, these two wefts coming between the pile loops in adjacent crossings of the binder warp.

'It should be7 noted that the three wefts which hold the loops within the crossings are located in the same place directly below the binder warp, this arrangement producing a better surface than that found in fabric woven according to my prior patent, in which one of the wefts holding the pile loops was beneath the Studer warps. When thus disposed, the two rows of loops4 included in a single crossing tended to bend inwardly toward each other, thus producing a less even distribution of the pile upon the 4surface of the fabric.

A further advantage of my present invention lies in the saving of pile warp as compared with the amount previously used..

As the pile warps are carried in the face of the fabric rather than at the back, the length of warp necessary to bring a given warp to the front of the fabric is materially reduced. The downwardly extending loop which passesaround the middle weft is also inaterially shorter in my present weave.

The figures of the design are found to be more evenly formed in the new fabric, largely due to the fact that the pile warps in passing through the face of the fabric are not diverted from their path by the heavy stuffer warps of the prior arrangement.

By placing five picks of filling instead of four within each crossing of the binder warps lf produce a thickerand heavier carpet through the single addition of the extra pick. This is a most desirable result, as

the filling or weft material is a cheaper material than that which composes the warps.

Tt should be understood that the number of warp threads and also the number of wefts within each crossing of the binder warps may be varied and that my invention i will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims and I do not wish to be limited to the de,v

tails herein disclosed, but

What I do claim is 1. A Woven pile fabric comprising stuer, pile and binder warps, and a plurality of filling threads or wefts within each crossing of the binder warps, said pile warps eXtending through said fabric immediately below the pile surface, said stuffer warps forming the back of said fabric, three of said wefts retaining the pile loops above the pile warp, one of said wefts separating the pile and stuffer warps, and the remaining wefts lying below the stufer warps.

2. A woven pile fabric comprising stuffer, pile and binder warps, and, a plurality of filling threads or we-fts within each crossing of the binder warps, said wefts extend'- ing in three planes, three of said wefts lying in an upper plane above the pile warps and retaining the pile loops above the pile warps, and the remainingwefts lying in two planes one above and one below the stuffer warps.

3. A woven pile fabric comprising stuEer, pile and binder warps, and a pluralityqof filling threads or wefts within each crossingrof the binder warps, said wefts extending in three planes, three of said wefts lying in an upper plane above" the pile warps and retaining the pile loops above the pilewarps, and one of said wefts lying in a lower plane below the stuffer warp, and the remaining wefts lying in a plane between the pile and stuffer warps.

4. A Woven ile fabric comprising Studer, pile and bin er warps, and five -filling threads or wefts within each crossing of the binder warps, said wefts extending in three planes, three of said wefts lying in an upper plane above the pile warps and retaining the pile loops `above the pile warps, one of said wefts lying in a lower plane below the stufer warp, and the remaining weft lying in an intermediate plane between the pile and stuffer warps. y

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
