ANDREW G. ROBERTSON,
or AUBURN, NEW YORK.
WOVEN PILE FABRIC.
Specification of Letters Patent.
Patented Jan. 5, 1909.
Application filed May 21, 1908. Serial No. 434,066.
To all whom it may concern:
Be it known that 1, ANDREW G. ROBERT- soN, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Woven Pile Fabrics, of which the following is a specification.
My invention relates to woven pile fabric such as that used in the manufacture of wilton, brussels and velvet carpets.
My invention articularly relates to that class of fabric inwiiich thepile loops are formed by the pile warp threads being passed over pile wires which are arranged, in the loom,
arallel with the said pile warp threads.
he said pile loops are bound in by filling or weft threads which are held by the binder warp threads, and the pile loops are then cut to produce wilton or velvet carpets.
The object of my invention is to provide a novel method of securing the pile loops so that they will not become loose and pull out. This trouble was due to the fact that the filling threads holding said; loops were slightly separated by the crossing of the binder war threads, which would leave one side or end of the pile loops unbound, so that it would not stand up straight and would easily pull out.
In my improved fabric the pile warp thread is held by two filling threads, one in each shed, at the point where the binder warp threads cross and I dispense with the loose ends of the pile warp loo s at the points where there is no fillin tiread next to it to hold said ends secure y and in an upright position.
Referring to the drawings: Figure 1. is a longitudinal section of my improved woven pile fabric, drawn on an en ar ed scale, showing the pile wire and the p' e loops uncut; Fig. 2. is a similar view showing the pile threads after they have been cut.
In the drawings A and B are the binder warp threads and C is the stuffer warp thread. The latter is used to give the fabric a heavier body. The upper filling or weft threads 1, 2 and 3 are arranged above the stuffer warp thread C and the lower filling threads 6 and 7 are arranged below the said stufier warp thread C. The binder warp threads cross at the points 10, 11, 12 and 13, and form the sheds 20, 21, 22 and 23, each of which embraces the three upper filling threads 1, 2 and 3, and the two lower filling threads 6 and 7.
' The pile warp thread D is held in the body of the fabric by the filling threads and the pile loops are formed by raising the pile warp thread D up from the body of the fabric and passing it over the pile wire E and securing it with the filling thread 2, thus one pile loop is formed. The pile warp thread D is again passed over the pile wire E and secured by the filling thread 3, and another loop formed. The lower filling threads are inserted in their proper order and the binder warp threads crossed to com lete one shed.
I When the pi e loops are cut by the knife F, on the pile wire E, each shed will contain four ends or tufts of pile threads, as shown in Fig. 2. Each end or tuft of the pile warp will be securely held in due to the fact that there is a ling thread on each side of said end or tuft to support the latter, and also in the body of the fabric.
After the shed is completed the pile warp thread D is not raised from the body ofthe thread 1 of the next succeeding shed has been inserted. Said pile war thread is then raised and passed over the 1 e wire and the 100 s formed as above described.
hen the fabric is beaten togetherand the loops of pile Warp thread are cut, the loose ends or tufts d and at will be firmly held between the filling threads 1 and 2. The ends d and (Z of the ile threads will be firmly held between the filing threads 2 and 3. The 100 of pile warp forming the ends of tufts d an (1 extends from one shed to the next suc oeedin shed and said loop is secured by the two fil ing threads 1 and 3, one in each shed. The loop of ile war forming the ends d and ri is hel by the ling thread 2.
There are no loose ends of pile threads between the filling threads 1 and 3 at the point where the binder warp threads A and B cross. It will be seen that each loose end is firmly bound in the body of the fabric and will be held in an upri ht position due to the fact that thereis a filling thread on each side of the end or tuft. By using three up er filling threads and two lower filling threads in each shed a greater tension is made on the binder warp thread at the top of the shed which an uprifglht position,
securely hold the same 8O fabric to form another tuft until the filling will causetheupper'filling threadsto be-drawn tightly together and securely hold the pile loops in place.
Any number of frames niay beused in" car rying' out my invention so that different colors of pile warp threads may be used i'nmanufacturing the fabric.
Having thus described my invention I claim and desire to secure by Letters Patent.
1. In a woven pile fabric, the combination of upper and lower filling threads, pile warp threads, binder warp" threads, said binder warp threads crossed to form sheds, a loop formed of said pile warp threads, said loop heldby anupper filling thread in one shed and b anupper filling thread in the next adjoining shed and another loop-held by an upperfilling thread in the cent-er of said shed.
2. In a Woven pilefabric, the-combination of upper and lower filling threads, pile warp threads, binder warp threads crossed to'form sheds to embrace said filling threads, a pile warp threadbound in one shed and having a standing end betweentwo of said upperfilling threads-of the next adjoining shed and a pile war thread bound by an upper filling thread in the center of said shed having. standing ends on each side of said last-mentioned filling thread. 7
3. In" awoven ilefabric, the combination of u per nd Tower filling' threads; pile warp threads, binder warp threads, said binder warp threads crossedto forrn sheds to embrace five-of said fillin threads, apluralityof loops formed of saidpi e warpth-reads inea'ch shed and havin "standing ends; said endsheld upright by a fil ing thread on each side ofthe' same, said ile thread forming the 10 op at the e'n-dsof each shed -being bound in the next adjoining shed;

5. In a wovenpile'fabric', the combination of upper and lower filling threads, pile warp threads, binderwarpthrea'ds crossed to form sheds, said shedscontaining three upper filling threads and two lower filling threads, a loop formed" of said pile thread held by the upper filling thread in the center of said shed, and a loopof said pile thread held by the uper filling'threadat the end of one shed and by the upper filling thread at the end of the next adj olning' shed.
