Application filed December 18,- 1914. Serial No. 877,969.

To all whom it may concern: Be it known that I, GEoRc SAUPE, a c1t1- zen of the German Empire, residing at Limbach, in the Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Warp-Knitted Fabrics and the Methods of Making the Same; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 1n the art to which it appertains to make and use the same.

My invention relates to improvements in warp knitted fabrics, and the object of the improvements is to provide a fabric of this class, which has the same appearance on both sides and in which the loops cover each other as distinguished from such fabrics in which the loops are located between one another. The fabric is made of two sets of warp threads and the threads of the sets run in opposition to each other and on each side of the fabric always in the same direction, and so that they form loops alternately on the opposite sides of the fabric. To obtain this result, the threads of each set are gradually transferred to the other set as they arrive-at the ends of the fabr1c, and they are gradually, returned with this set to the opposite end of the fabric, so that all the threads ar assed through an endless path. Thereby a fabric is produced which is perfectly uniform, all the loops lying in the same direction and having the same appearance, and there are no transverse stripes or the like, such as are produced in fabrics of this class in which the threads run on the same side of the fabric in opposite directions. My improved fabric is particularly suitable as a substitute for deer skin, because after dressing and grindingit resembles very nearly the deer skin as to appearance and elasticity, andmore particularly the Danish kid.

The looping can be made in different ways, and it depends onthe paths of the warp threads when being laid over two. successive rows of needles, which path is termed in warp knitting the lap.

v For the purpose of explaining the invention two examples embodying the same have been shown in the accompanylng drawings, in which the same letters of reference have been used in all the views to indicate corresponding parts. In said drawings-- Figure 1, is a diagram illustrating the lap of the fabric,

Fig. 2, isa similar diagram illustratin a modified lap,

Fig. 3, is an enlarged diagrammatical plan view of the needles and illustrating the manner of placing two threads thereon,

gig. 4, is an enlarged view ,of the fabric, an

Fig. 5, is a plan of Fig. 4 with the loops displaced from their actual positions.

In Figs. 1 and 2 I have shown two fabrics having different laps for one thread 3 of one of the sets of warp threads and for a thread 4 of the other setof warp threads.

The rows of points 1 and 2 indicate the two rows-of frame needles which, as shown at the left of Figs. 1 and 2, turn the backs to eachother but are disposed exactly opposite each other as is shown in Fig. 3, while in Figs. 1 and 2 for the purpose of illustration the said needles are shown as being staggered with relation to each 0ther, the

rows II, III, IV, etc. being a further represensation of the same rows of needles ,on which rows of loops are successively formed.

The number of the warp threads is the same as that of the frame needles, and the said threads and also the frame needles are divided into two rows. These threads are placed on the frame needles so as to cross each other in pairs.

In the example. shown in Fig. 1 the threads 3 and 4C are first placed below a needle a and thereafter over a needle 6 of the front row 1, whereupon they run laterally between the two rows of frame needles and to a needle 0!, and. finally they are placed over the frame needle (Z. Each time the threads have been laid over the frame needles, they are formed into loops, so that a row ,of loops I (Figs. 1 and 4) is produced on the rows of frame needles after the warp threads have been passed through clearness sake these loops have been shown in Figs. 4 and 5 as being staggered with-relation to each other, but practically they as to cover each other.

are located exactly one behind the other so In the following rows of loops, for example in the rows II to VII shown in Figs. 1 and 4 the same path or lap of the warp threads is repeated in the same direction.

In Fig; 2 Ihave shown a lap in which the threads of each row run likewise in opposition to each other and so as to describe similar paths. However, this path is distinguished from the one "described with refermade without departing from my invention.

I claim herein as my invention:

1. The herein described warp knitted fabric, which consists of loops located on opposite sides of the fabric and one behind the other, and consisting each of two warp threads, the threads running on each side of the fabric in opposite directions, and each thread running on each side of the fabric always in the same direction.

2. The herein described method of mak-' ing a warp knitted fabric, which consists in producing loops from two setsof warp threads alternatelyon opposite sides of the fabric being formed, gradually passing the threads of each set from one end of the fabric to the opposite one and in opposite directions, and gradually transferring the threads arriving at the end of the fabric being formed respectively from their set to the other one.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses."
