PILE FABRIC.

Application led November 24, 1925. Serial No. 71,200.

This invention relates to pile fabrics, and more particularly to `pile fabrics of the type known as VVilton'carpets.

It is an Object Ofmy invention to provide an improved const-ruction of pile fabrics of this type. i t

It is a further object of my inventionto provideV an improved method of binding the pile tufts in place.

l0 Other Objects and advantages of my invention will be apparent from thefollowing description, taken in conjunction with the accompanying drawings, which form a part of this specification, and in whichi y Figure 1 is a longitudinal section of my improved fabric on an enlarged scale, showing some loops cut and Others uncut; and

Figure 2 is a diagrammatic plan view of the same. i

My improved fabric consists of binder, stuifer and pilewarp threads combinedwith iillingthreads arranged in three horizontal planes. There are iivepicksof filling'between each cross of the binder threads.I and the filling threads in the upper plane are preferably different from those in thetwo lowerplanes. `Two loops are formedover a stationary pile wire from a single pile warp thread between each crossing of the binder threads, and the cutting of these loops provides four tufts in each shed. The connected pairs of tufts thus formed from a single pile warp thread are displaced laterally from each other by a longitudinally disposed warp 85 thread, and are secured by looping around filling threads in the two upper horizontal planes. The pairs of tufts are thus dis-` placed both laterally and vertically from each other.

ings, 10 and 11 denote binder warp threads, 12 and 13 stuffer warp threads, and 14 a pile warp thread. The stuii'er warp threads 12 and 13 do not cross in the fabric,vwhereas the binder warp threads`10 and 11 cross be tween each five picks of filling. The filling Ywill describe merely the cycleof movements Referring more particularly to the dravw .10 and l1 as shown,` and the filling threads in the upper plane, 15` and 19, are prefer `ablyof a sinallerdiameter than the remaining filling threads, 16, 17 and 18. The diameters of the respective filling threads are preferably so chosen that thersum of the diameters of the upper filling threads 15 and 19 and the four intervening pile tufts approximates the combined diameters of the filling threads 16, 17 and 18 in the two lower planes. By this construction a fabric of exceptional balance and compactness is produced. It willbe apparent that when the fabric is beaten up, the upper and` lower planes of filling in each shed of the binder threads will be of substantially the same size.

This fabric may be woven on a pile fabric loom of the stationary pile wire type, commonly employed in .weaving Wilton carpets. The construction and Operation of such looms are well known to those skilled in the art, and therefore, instead of describing in det-ail the `manner of weaving the fabric, I

of apile warp thread in relation to the other threads and to the stationary wire.`

As shown in the drawings, the first pick of `filling 15 is inserted below one of the binder warp threads andabove all the other threads. The pile warp thread 1,4.` is raised from its position under thel filling thread 15, and while the pick 16 is being inserted below all of the threads except the other binder warp thread, it is passed over a sta tionary pile wire, and then down into the shed on the other side of the stuier thread 12. At this point pick 17 is inserted above the pile thread 14 which is then raised by the heddle, and passed back over the stationary` wire while pick 18 is being inserted. The pile threadcis put back down into the shed on` the side of stufer thread 12 to which it was originally adjacent. The pick 19 is then inserted over it, the binder threadsloo crossed, thereby completing the shed, and

the cycle repeateduutil the desired length of fabric `is attained. The loops formed upon the pile wire slide forward from the making point as the fabric is woven, until `they come in contact with a knife edge formed On the pile wire by which they are severed, thereby producing the cut pile tufts. vFigure 2 `is notV strictly an accurate plan view in that it showsthe filling threads, 15 110 and 16 and 19 and 18 respectively, arranged to one side of each other instead of in strictly vertical relationship, as is actually the case. This is done for the sake of clarity in disclosing the invention.

lt will be noted that by this construction the filling threads are arranged in three planes, and one pair of tufts engages the lilling threads in the upper plane whilethe next pair formed from the same pile thread engages the filling threads in the middle plane, thereby spacing the tufts vertically. The tufts are also spaced laterally by the stuffer threads. This produces a very attractive weave in which the tufts are eXcep tionally firmly bound', and the use ofthe different kinds of filling threads in the various planes adds to the appearance and util.- ity of the fabric.

Many alterations or modifications might be made in the structure above described without affecting the spirit of my invention, and my invention therefore includes all such changes which fall within the scope of the appended claims.

Having thus descrlbed the invention, what I claim as new and desire to secure by Letters Patent is:

1. A woven fabric comprising binder, stuffer and pile warp threads, and five filling threads within each crossing of the binder warp threads, said filling threads being arranged in three planes, two in the upper plane, one in the middle plane, and two in the lower plane, a loop of said pile thread being held by the upper filling thread at the end of one shed and by the upper filling thread at theV adjoining end' of the next shed, a loop of said pile thread being held by the filling thread in the middle plane, said pile eters of the filling Vthreads in the two lower planes. Y

3. A woven pile fabric comprising binder, staffer and pile warp threads, and five filling weft threads within each crossing of the binder warp threads, said filling threads being arranged in three planes, two in the upper plane above the stu'er warp threads, one in the middle plane between the stufier warp threads, and two in the lower plane below the stulfer warp threads, a loop of said pile thread connecting two pile tufts being held by the upper filling thread at the end of one shed and by the upper filling thread at the adjoining end of the next shed, another loop of said pile thread connecting two pile tufts being held by the lling thread in the middle plane, said pileithread being cut to form four `standing tufts in each shed, and successive connected pairs of tufts formed from the same pile thread being displaced laterally by a staffer warp thread.

4; The combination as claimed in claim 3 in which the diameters ofthe filling threads in the upper plane are less than the diameters of the filling threads in "thetwo, lower planes.

In testimony whereof I hereunto alfix my signature.

GEORGE CROSSLAND. Y
