KNITTED FABRIC.

To all whom it may concern Be it known that I, FRANK CLEWLEY, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Knitted Fabric, of which the following is a full, clear, and

exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a new and improved fabric especially adapted for towels, wash cloths and other similar goods which are frequently soiled and wetted and which it is important, from a sanitary standpoint, should be such open mesh as to be capable of being quickly and thoroughly dried. In a atent issued to me February 16th, 1904, No. 52,033, a fabric of this character is set forth in which chains of knitted loops, each chain composed ofa single weft thread, are united by warp or filling threads alternately deflected to the right and left. This fabric meets all sanitary requirements but when applied to certain goods it does not possess the strength in the line of the weft that it is desirable for it to have.

The object of the resent invention is to provide a knitted fa ric posessing a maximum of strength on the line of the weft.

The invention consists of a fabric having chains of knitted loops, and filling threads alternately deflected to the right and left, as in said patent, but in which each chain of loops is formed by means of two separate weft threads forming alternate loops of the chain, and consists also of a fabric wherein the filling threads are interlaced with the weft threads in a particular manner that will be clearly apparent from the following description in. connection with the accompanying drawings, which illustrate a referred embodiment of my invention an in which Figure 1 is an enlarged face view, and

Specification of Letters Patent.

Patented May 11, 1915.

Application filed A ugust a4, 1914. Serial No. aaaaas.

d and e is the same as that of the weft threads, but they are alternately deflected to the right or the left either between adjacent chains or across two or more adjacent spaces between chains; each of said filling threads extending, in its passage through each loop, between two weft threads at and b of a pair. Starting with either weft thread of any one of the chains (say the weft thread a at the second loop from the top of chain as), it will be observed that it extends down and through the third loop, formed by thread I) thence up and through the first loop, formed by thread I); thence down to complete the second loop and again through the third loop, and continues down through the fifth loop, formed by thread 6; thence up and again through the third loop; thence down to complete the fourth loop: and so on. Starting with the weft thread 6 at the third loop of the same chain w, it extends down and through the fourth loop, formed by thread a; thence up and through the second loop, formed by thread a; thence down to complete the third loop and again through the fourth loop, and continues down through the sixth loop, formed by thread a; thence up and again through the fourth loop; thence down to complete the fifth loop: and so on. Thus each weft thread extends alternat'ely up the length of one loop and down the length of three loops and in its passage up and down extends thrice through each loo formed by the other weft thread.

ach filling thread extends, in its passage through a loop, back of two sections of one weft thread and in front of one section of the same weft thread and one section of the other weft thread. If the filling thread, in its extension in one direction across the fabric, after passing through one loop, does not extend beyond the corresponding given chain, it is deflected, in the opposite direction, through the loop below it and thence across to the next chain and through the loop thereof corresponding to the last named loop of the first chain. If the filling thread, in its extension across the fabric, passes across a plurality of successive spaces, it extends successively through corresponding loops of successive chains, and in its return in the oppositr direction, is deflected first through the neat lower loop of the last chain.

Thus starting with the filling thread a to the left of the first loop of chain 2:, it will be observed that it extends to the right through the first loop of chain a; and the first loop of chain 1 thence to the left throu h the second loop of chain 3 and the secon loop of chain to; thence to the right through the third loop of chain a: and the third loop of chain y; thence to the left through the fourth loop of chain 3 and the corresponding-loops of chains 22. w and o, thence to the right through the fifth loops of chains '0, w, a: and 3}; thence to the left through the sixth loops of chains y, 0:, w and o, and thence back and forth through corresponding loops of chains 11 and w as above described. 7

In the particular fabricshown in the drawings, the chains are divided into sets of four, while the filling threads are divided into sets of three (0, d and e). In those sections of the fabric in which each-filling thread extends across only a single space between chains, two adjacent sets of chains are unconnected, forming an open space. Thus an open space is formed between chain a: of one set of chains and chain 10 of an adjacent set of chains. In those sections of the fabric in which a filling thread iscarried across a lurality of spaces between chains, two of t e three threads are carried across the space between adjacent sets of chains, thus closing the space between the sets of chains.

The method of operating the needles whereby the above fabric will be formed will be apparent to one skilled in the art, and as such operation forms no part of the invention, the same is not described.

While I have differentiated the weft threads 0. from the weft threads I) by section-linin the one and not the other, it will be 111111 erstood tilliat this is donililnerely to assist t e eye in 'stinglnshin' g e two threads in the drawings, it being understood that these threads are similar one to the other and interlace with each other and with the filling threads in precisel the same way. Also the two filling th 0, d and e are of like character and are given difierent reference letters because, in the fabric shown, three of such threads areemsloyed in each set of chains to form a close block separating two open spaces.

It will be understood that the number of chains and the number of threads in each closed block and the number of chains spanned by the filling threads may be varied without departing from the invention.

While I have called the lo 'tudinally extending looped threads weft and the uniting cross threads warp or filling threads, they may be not improperly otherwise designated, as, for example, the looped thread may be termed warp threads and the other threads weft threads.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. A knitted fabric comprisin a weft formed of a number of pairs 0 threads forming chains, each pair of threads ex-,

tending along only a single chain and each thread of a pair forming loops interlaced with the 100 s of the other thread, and a warp formed of filling threads extending back and forth between and interlaced with the chains.

2. A knitted fabric comprising a weft formed of a number of pairs of threads forming chains, each pair of threads extending along only a single chain and the two threads of each air formin alternate filling threads extending back an forth between and interlaced with the chains.

3. A knitted fabric comprising a weft formed of a number of pairs of threads forming chains, each pair of threads extending along only a single chain, each thread of a pair extending successively forward, backward and forward to form a loop engaging loops of the other thread respectively in front and back of the first loop and thence extending successively forward,backward and forward to form a loop beyond and interlaced with said forward loop of the second thread, and so on, whereby a chain is formed composed of alternating loops, and a warp formed of filling threads extending between and interlaced with the chains.

4. A knitted fabric comprising a weft formed of a number of pairs of threads, the two threads of each pair forming alternate loops of a continuous chain of loops, each thread in the formation of a complete loop extending through one of the adjacent loops formed by the other thread thence through the other ad'acent loop formed by the last named threa and thence through the first adjacent loop to the next loop formed by the first thread, and a warp formed of filling threads extending back and forth between and interlaced with the chains.

5. A knitted fabric comprising a weft formed of a number of pairs of threads, each thread of a pair being interlaced with the other thread of the pair to form a continuous chain of loops, and a warp formed of filling threads deflected back and forth between the chains and extending, at each point of interlace with a chain, between the two weft threads of a pair.
