Application filed March 31, 1919. Serial No. 2863314.

rics of the type or class which havetheir loops or terry formed by the reed beating up the weft to different positions (a system of weaving which is well understood) one of the difliculties encountered is to have the terry warps or loops so bound'into the body of the fabric that they will retain their positions firmly. Many methods of shedding or treading the threads of warp and many kinds of warp threads and the treatment of same have been used and followed to attain the object desired, however according to my present invention I sointerweave the terry warp threads with the weft threads that these latter interlock with the former in such a manner that any pull on the terry or loop warp threads tends to cause same to grip-certain of the weft threads more firmly between them, thus a pull on the terry warp 'p I through the 3rd and Acth'healds while the tworemaining ground warp threads next succeeding are again: taken through the 5th 'andbth healds. 1 The order" of treading cannot so readily draw out the loops which are now held and locked in a fixed position, while the order of shedding which I follow is such as "to give adistinctive appearance to the resultant fabric and one that enhances itsvcommercial value. Y

In order that my said invention may be readily understood, I have hereunto appended a sheet of drawings illustrative of the method in which the threads of warp are operatedand theorder in which such operations are carried out." r

Figure" l is a diagram illustrating two threads of warp and the order in which same pass over and under the threads of weft, to form the ground of the fabric.

Fig. 2 is a similar diagram to illustrate four threads of warp as being interwoven with the weft to form the pile or terry part of the fabric. 7

Fig. 3 is a plan showing the order of treading the threads of warp.

Fig. 4 illustrates the drawing in plan or the order in which the threads of warp are passed through the healds.

In Figs. 3 and 4 the heald shafts are reppicks.

resented by the lines 1, 2,3, 4, 5, and 6,

while the pile or terry warp threads are represented by thelines a, a and b, 6 and the ground warp threadsby the lines 0, 0 and (Z,"(Z I The shots of weft are represented in Figs. 1 and 2 by the blackened circles g..

In accordance with my invention (with the modifications hereinafter described). I arrange the terry warp threads "a, a and Z), 6 to be in pairs, that is to say, where a single terry warp thread has been heretofore used I now-use two of such warpthreads and I arrange one pair a and b to form the loops 7 on one side of the fabric at one time while the adjoining pairs (1 and 72 form the loops 7 on the other side thereof at the same time, said order being alternatively reversed. In conjunction with this arrangement of I, I

terrywarp threads, Iuse a warp weaving ground with four'threads a, o and d, d for each four threads of the terry warp threads.

threads of ground warp 0, "0 are taken through the 5th and 6th healds, the 'neXt air of terry threads are a 6 aretaken or shedding as shown-byFig. 3 of the drawingsis plain for four picks by the ground shafts 5 and 6;

Theshaft 5 then remains down for two picks and the shaft 6 remains up for two The next fourpicks are plain while during the next two picks the shaft 5 is up and the shaft 6 is down for both picks, the

The crossesshown on the shafts, 1, 2, 3 and 4 show which shafts are raised, while shaftswhich areraisedbeing shown by crosses on the shafts 5 and 6 Fig. 3.

the absence of such crosses shows where the hence it is slightly shorter or does not extend as far from the body of the fabric.

This formation of longer and shorter loops adjoining each other gives the resultant fabric a distinctive appearance not otherwise attainable.

-As a modification of the weave hereinbefore 7 described, I nlay make use of terry warp threads arranged in groups or series of three, four or more threads adjoining each other, that is to say, when I use three threads I shall have two threads at with a 'thread 6 arranged between them and when I use four threads then I shall have one thread a adjoined by a thread 6 which has on the other side of it another thread a V which again is adj oined by a thread 6, these orders ofarrangement of the threads at and Z) 7 being repeated as greater numbers aroused. jWhen I employ said arrangements of threads I 'm'ay'break the treading of them'so that they are split up into (as near as possible) a plain weave before and after (orbetween) their loop formations so as top-reduce, by the treading of these terry threads and the treading of the ground warp threads, a; plain .weave or one as nearly plain as is possible entirely around each pair or bunch of loops. By arranging the terry threads to adjoin each other in pairs (or in other numbers) -andtreading all the warp threads so that each pair or bunch of loops is surrounded by .a weaveas nearly as possible plain I find that the loop or terry'warpthreads are firmlyheld since any pullon any pairor bunch of pile-threads will cause thethread encircling the extra'pick of weft to press saidweft against'the next pile thread and so look itin position in such a way that the greater the pull the firmer they grip the weft and consequently the firmer will the loops be secured.

The fabric produced, as hereinbefo-re described, may be woven in a common one shuttle terry loom, but I have found that the order of treading'is'such that on-using two kinds of weft with. those threads which are gripped by the terry warp being of a thicker, thinner or otherwise different character from the other threads, a further distinctive and novel appearance is given to the resultant fabric.

It is-obvious'that'where more than one kind of weft is used, the loom will have to have a correspondingly increased number of shuttles.

Such being the nature and object of my said invention, what I claim is V 1. A terry-fabric composed of terry warp threads arranged in pairs, one thread of one pair being made to take over two threads of thread of said pair taking over three threads of weft also to form a 1001), while the" two weft over which it forms a loop, the other 1 threads of the pair of terry warp threads 7 adjoining the former pair are, arranged, so that one ofthis secondary pair'of'threads takes under two threads of weft to forma loop and the other of said second pair of threadstalres under'th-ree threads of weft,

'alsoto formaloop, thus formingterry-loops of two sizes on both sides of the fabric.

' 2. A terry fabric composedof terry warp threads arranged in sets of three, two of the threads ineach' set being arranged to take j over two threads .of weft to form loops, the

other'thread in the same set being made'to take over three threads of weft over which they also formloops, while the sets ofterry threads adjoining the former 'set are arranged sothat oneof-themtakes-under two threads of weft to form-loops, the remaining two threads in the same setbeing inade to take under threethreads of weft to form loops,-said resultantloops being of two sizes on bothisidesof the fabric.

3. In the production of a terryrfabric com posed of terry warp threads arranged in pairs one thread of one pair. being made to take over two-threads of weft over which it forms a loop, the other thread of saidpair taking over 'three'threads'of weft also to form a-loop and one of the second pair of threads takes under three threads of weft while the other threadof said second" pair
