KNIT FABRIC.

SPECIFICATION forming' part of Letters Patent N0. 577,702, dated February 23, 1897.

Serial No. 575,434. (Specimens.)

T0 a/ZZ whom it 77mg/ concern.-

Be it known that I, THoMAs J. WooDoooK, of Philadelphia, (Germantowm) in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Knit Fabric, of which the following is a full, clear, and exact description.

My invention relates to knitted fabrics, and the object of the invention is to provide a knitted fabric especially designed for the body portion of hammocks, but which may be also used wherever a particularly strong knitted material is required.

A further object of the invention is to` produce a knitted fabric in which the warp will be crossed by chain-stitches in such a manner as to firmly bind the Warp and to produce a material which will have the least possible tendency toravel if punctured 0r torn.

The invention consists in the novel combination of the threads comprising a knitted fabric, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure is a plan view of a piece of the fabric, illustrating the manner in which the warp-threads are connected and crossed by the chain-threads, the threads being exaggerated and widely spaced, so that their relation to each other may be more clearly traced. 4

In the construction of the fabric two sets of warp-threads A A are employed, the said threads being arranged in serpentine form, one in rear of the other, with the bights of the two sets turned in opposite directions and overlapping one another, so that the overlapping portions thereof form a series of rings a, as shown. The straight portions l0 of the warp-threads lie in parallel planes, and the bent or return portions 1l of each set of warpthreads are opposite to and in a measure eX- tend within the open spaces between the straight portions of the next or adjoining thread of its set.

The fabric is produced upon a warp-knitting machine having, in addition to the usual guides for the knitting or chain threads B, supplemental guides for the warp-threads A A', the latter being moved back and forth a space of two needles after the completion of each course of loops upon the needles of threads B, the result being that the loops of threads B inclose the bights or other portions of threads A A in the manner shown.

Each thread Bis continuous and forms a chain of stitches or loops, which consists of loops l2 and connecting portions 13, the loop proper and the connecting` portion lying upon opposite sides of and inclosing and connecting the bights of the adjacent warp-threads of each set. In this manner the chain-threads serve to connect the warp-threads securely together and constitute a body or filling for the fabric of superior character and one through which an object of comparatively large diam eter may be passed without tearin g the threads, as the threads will open for the passage of the object, and if a thread should become broken the opening made thereby will not be so liable to increase in size as it would in the ordinary knit fabric.

Having thus described my invention, I claim and desire to secure by Letters Patentl. A knit fabric composed of warp and knitting threads, the warp-threads being arranged in two sets one in rear of the other, the threads being in serpentine lines with the bights of the two sets turned in opposite directions and overlapping as shown, bights of adjacent threads of one set of warps being connected by one set of the knitting-threads and bights of adjacent threads of the other set of warps being connected by the other knittingthreads, substantially as described.

2. A knitted fabric composed of warpthreads arranged one in rear of the other, the threads of each set being in serpentine lines with the bent or return portion of one thread opposite to and extending a short distance between the straight portions of the adjacent thread, the threads of the two sets being turned in opposite directions and overlappin g one another, and knitting-threads alternately connecting two bent or return portions of one set of warp-threads with a straight portion of the other set of warp-threads, substantially as herein shown and described.
