WOVEN PILE FABRIC.

SPECIFICATION forming part of Letters Patent No.484,541, dated October 18, 1892.

Application filed November 13, 1890. Serial No. 371,289. (Specimens.)

T0 all whom it may concern/.-

Be it known that I, FRED PEARsoN, of the city of Philadelphia, and State of Pennsylvanla, have invented a certain new and useful Improvement in Woven Pile Fabrics; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification.

My invention has relation to double pile fabrics, and particularly to plain plnshes; and it consists in the weave and construction, hereinafter particularly described.

The object of my invention is to provide, in a novel weave, a construction materially different froIn any heretofore invented by me or by others, a plain double pile fabric having an even surface presenting` the appearance of one even mass of pile without' pile marks or ridges appearing across the goods.

A further object is to provide at the same time a substantial fabric so constructed as to prevent the pile from ypushing out through the back, and also to prevent the pile from losing its approximate Vertical position and the vthreads from becoming crossed or matted.

I do not herein claim Vor seek to cover, broadly, the idea of arranging, in connection with ground Warp-threads and ground weftthreads and with tufts of pile engaged with picks of said ground weft-thread, a second set of weft-threads the picks of which are im mediately behind the picks of ground-weft with which the tufts of pile are engaged and a second set of warp-threads which bind said second set of weft-threads to the ground weftthreads, as such broad idea or invention is embodied and claimed in an application filed by me in United States Patent Oliice-ongthe 31st day of March, 1891, Serial No. 387,114.

In my improved weave herein described I preferably employ four binder or warp threads and one pile-thread in one reed-space in weaving double pile fabrics. Each pile-thread appears as in pairs in each fabric, each pilethread of a pair formed, respectively, on opposite sides of the saine pick and on every other pick in a series, apick intervening between each pair of pile threads thus formed in the same line. A warp-thread is arranged 011 the face of the fabric, preferably from the saine reed-space on each side of the said pilethread, similarly shed with relation to the weft, one warp-thread passing through the entire fabric and the other through the upper or face series only ofv the picks. An additional pick is formed back of each pilethread, thus securing it between two picks, which picks are bound together by series of Warp or binder threads, preferably two in number, formed alternately over and under the two series of picks or weft-threads, thus forming in each fabric an additional or auX- iliary backing.

In the accompanying drawings similar letters of reference refer to similar parts throughout.

Figure l is a sectional View of the double pile fabric before the pile is cut, as on the line am; of Fig. 2. Line w w indicates the line of severance of the pile-threads in dividing the fabrics. Fig. 2 is a partially-sectional plan vieW on the liney y of Fig. l. Fig. 3 represents a bottom View of the fabric. Fig. lis a sectional view of the fabric on the line z .e of Fig. l.

A represents one series of binding or warp threads, and A the corresponding binding or Warp thread between which the pile-thread ct is interwoven with the picks j). B B are also binding or warp threads, between which the pile-thread b is interwoven,also,with the picks p. Said warps A A and pile-thread a are formed in a separate reed-space from the warps B B and the pile-thread b. The said Warps A B are interwoven with the first or upper series of picks 1J.

Back or underneath the first series of picks p is formed an additional auxiliary series of picks p', between which two series the pilethreads aandbare bound. The warpsAand B form the binder Warps orthreads of the upper or lirst series, the picks passing over and under every pick alternately up and down and bind the said picks p together, While the Warps A and B form the binder warps or threads for the two series of picks p p', passing over and under said two series of picks p p alternately up and down, and bind the two series of picks and the whole fabric together. hile the two series of warps A A are formed in the same reed-space, the warp A does not IOO pass through the entire fabric, but only over and under the Iirst or upper series of picks p, while the warp A passes through the whole fabric over and under the two series of picks p p alternately, the same process occurring with the warps B B', respectively, in a separate reed-space. Between the warp A and B no pile-threads are preferably employed.

A number of weft-threads may be thrown with each shot of the shuttle, forming a single pick instead of a single weft-thread. The pile-threads a and Z) are thus bound and secured firmly in the fabric, having in the length of the goods on each side of each pilethread a separate warp and on the remaining sides a separate pick, thus binding the pilethread rmly on four sides into the fabric and preventing any lateral displacement, while on the back of each pile-thread is formed the additional or auxiliary backing, which prevents the pile being forced out through the backing. The picks on which the tufts of pile are formed are preferably those of the face or upper series which are depressed by the warps passing over the outer surface or face of the pick, which thus binds thetuftformed onthe said picktightlybetween the said upper pick and the pick of the fabric formed immediately underneath the saine. It

will be clearly seen that the pile-threads are thus bound rmly into the fabric and prevented from being pushed out orlosing their proximate vertical position, and in the arrangement and construction described the ridges or pile-marks common in plush fabrics are also thus obviated and done away with, and the pile surface presents when the double fabrics are cut apart a snioothand even appearance.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The herein-described pile-fabric, having two sets of picks, one set formed underneath the other and bound together by binderthreads, and tufts of pile formed in pairs and in series between two parallel warp-threads on each side of every alternate pick of the face series of picks and caught between-the upper and under series of picks, the proximate series formed on alternate picks from that of the next series, substantially as described.

2. A pile fabric having a double set of picks, one set formed back of the other and bound together by alternate binding-warps, the upper series bound, also, together by separate binding-warps, and tufts of pile bound and secured between the said two sets of picks, each tuft of pile formed on alternate picks of the face series of picks in series and each tuft bound between two warps, one on one side passing through the entire fabric and the other on the other side passing through the upper series of picks only, substantially as described.

Apile fabric havinga double set of picks, each set formed back of the other and bound together byalternatebinding-warps,the'uppet' series bound, also, together by separate binding-warps, and tufts of pile bound and secured between the two sets of picks, the tufts of pile of each series being formed on every other pick of the face series-of picks, said picks on which the tufts are formed having the warps on each side of the tuft passing over theupper or face surface of the upper series of picks and partially depressing the said pick, substantially as described.

4. A pile fabric having two sets of picks, one set formed back of the other and ,bound together bybinderwarps,and tuftsof pile formed in pairs and in series between two parallel warp-threads on each side of every alternate pick of the face series of picks and caught between the face and back series of picks, the approximate series of pile tufts formed on alternate picks from that of the next series, one'of the parallel warp-threadsion one side of the pile tuft passing through the entire fabric and the other on the other lside passing through the upper series only of picks, substantially as described.

5. A pile fabric having the double series of picks p p', binding-warps A B', bindingthe two series of picks together, and bindingwarps A and B for the face series of picks p, and pile tufts a b caught between the two series of picks p p on every alternate pick of the series of picks 19 in series, said pile-threads a formed in series on alternate picks from those on which the series of pile-threads b are formed, substantially as described.

6. The herein-described double pile fabric, woven one above the other and connected only by interwoven pile-threads, each fabric having two sets of picks, one set formed underneath the other and bound together by binder-threads, and pile-threads passing from one fabric to the other and formed on the face series of picks in pairs in each fabric and in series between two parallel warp-threads on each side of every alternate pick and caught between the upper and under series of picks of each fabric, substantially as described.
