KNITTED GOODS AND METHOD OF MANUFACTURING THE SAMTE.

SPECIFICATION forming part of Letters Patent No. 472,875, dated April 12, 1892. Application iiled July 15,1891. Serial No. 399,578. (Specimens.)

YTo all whom it may concern:

Be it known that I, HENRY J. GRIswoLD,a citizen of the United States, residing at Madison, in the county of New Haven, .State of Connecticut, have invented certain new and useful Improvements in Knitted Goods and Method 0f Manufacturing the Same, of which the following is a specification.

My invention relates to the manufacture of ribbed tops, cuffs, skirts, and other circularknitted fabrics requiring welts; and my invention consists in lknitting such articles in continuous lengths, and preferably insemidetached sections, each section with a Welt and capable of ready separation from the adjoining sections, witliout danger of cutting or otherwise injuring the welt or rendering the fabric liable to fray out, as fully set forth hereinafter, and as illustrated in the accompanying drawings, in which- Figure 1 shows a continuous circular fabric knit in semi-detached sections' adapted to be severed and embodying my invention. Fig. 2 is an enlarged view indicating the character of the union between the semi-detachedA sections. Figs. 3 to 9 are diagrammatic views illustrating the manufacture of the improved fabric.

In carrying my invention into practice I make use of an ordinary ribbing knitting-machine having a cylinder with needles and a dial with other needles-s uch, for instance, as the .knitting-machine for which Letters Patent of the United States were granted to me March 17, 1891, No. 443,337. The operation of such machine in producing my improved fabric may be readily understood by reference to the diagrammatic views of the accompanying drawings, in vwhich a represents one of the cylinder-needles and b one of the dialneedles, it being understood that the operation described with the two needles represented are those which take placenpon the ent-ire series of needles in the machine.

Assumin g that a portion of the circular fabric has been knit and that it is desirable to form a welt and then thereafter continue the knitting of the circular fabric, the operation lis as follows: Having knitted aportion of ordinary ribbed fabric C., Figs. 1 and 2, I put the ribbing-needles out of action, a loop 2 be ing retained upon each ribbing-needle, as shown in Fig. 3. With the cylinderneedles still remaining in action, I knit several rows to make a short section 4 of plain fabric, to prevent the work raveling back. I then break the yarn off or withdraw the yarn-guide, so as to prevent the yarn being fed to the needles during one revolution of the machine, which causes the stitches to be cast o if from the cylinder-needles, leaving the'portion 4 detached, the work remaining suspended from the ribbingfneedles by the series of isolated or separated loops 2, as shown in Figs. l and 5. Now to form a fast welt on the following section c', one revolution is given to the machine when the latches of the cylinder-needles will be opened. The ribbing-needles then being put into action and yarn being fed to the needles, by one revolution of the machine loops are placed uponboth cylinder and ribbing needles, as shown in Fig. 7, the ribbing-loops 3 being drawn through the previous loops 2. Now the ribbing-needles are again put out of action, the Work being suspended from them by the loops 3 as it was before suspended by the loops 2v. While the ribbing-needles remain out of action I knit several plain rows to form a section 7 Fig. 8, and I then put the ribbing-needles into action and unite the series of loops 3 with the last row in the portion 7, as shown in Fig. 9, thus forming a fast round welt, after which I proceed to knit the remainder of the section C in ordinary ribbed work. A slack course may be knitted a few courses from the end of each section, as is usual, serving as a guide for running the ribbed top or cuff onto the plain knitting-machine. After the desired number of sections have th us been knit together in one continuous fabric, as above described, they may be very readily disconnected by cutting through the loops 2, (the draft on which in knitting stretches them much beyond the length they would otherwise have,) therebyleaving each section of fabric with a welt w upon one end and at the other a loose course to facilitate putting onto the needles of the machine'for forming the leg of a stocking or other article.

During the last course, before putting the dial-needles out of action previous to commencing the welt, I may introduce a strong linen or cotton thread, which may be drawn out to sever the articles one from the other instead of severing the loops 2, as described.

If this method of knitting semi-detached sections is used in connection with twoand one, three and'one, or other than one and onev ribbed work, it will be necessary, in order to produce a fast Welt, to put every alternate cylinder-needle out of action in making the first two or three courses of the Welt.

I claim as my invention- 1. Acontinuous circular-ribbed knitted fabric consisting of a series of sections, each having a fast welt at one end and each section connected to the adjacent section by a series ofsolated loops and having a section of plain fabric 4, substantially as set forth.

2. As a new article of manufacture', a continuous circular-ribbed knitted fabric in sections connected by a series of isolated loops, each extending from one section to a welt of the adjoining forth.

section, substantially as set y 3. The Within-described improvement in the art of knitting circular-ribbedv fabrics with welts, the same consisting in knitting a body-section c of ribbed work, then throwing the ribbing-needles out of action, with their loops retained upon them and knitting a section 4 upon the cylinder-needles only, then throwing the stitches off of the cylinder-needles, and then putting the ribbing-needles into action 'and kniting one course on all, the needles, then again throwing the ribbing-needles out of action, with their loops retained upon them and knitting a section upon the cylinder-needles, and then throwing the ribbingneedles again into action and knitting ribbed Work, as usual.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing Witnesses.

' HENRY J. GRISVOLD.
