stitches is a slow, arduous, and consequently To all whom it may concern:

Be it known that I, ROBERT W. S0o'1'1, a citizen of the United States, residing in Leeds Point, Atlantic county, New Jersey, have invented certain Improvements in \Velted Knitted Webs and Making Same, of which the following is a specification.

The object of my invention is to produce, automatically and in a simpler manner than before, a turned welt upon the end of the leg, sleeve or body of a knitted undergarment, and. particularly upon the top of a stocking leg, an object which Iattain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a side view, partly in section, of a stocking, having, at the top of the leg, :1 turned welt made in accordance with my invention; Figs. 2 to 8, inclusive, are sectional views of suflicient of the elements of an ordinary circular knitting machine to illustrate the method of carrying out ,mv invention; Fig. 9'-is a view illustrating the method of constructing a special form of turned welt constituting part of my invention; Fig. 10 is an enlarged diagram, illustrating the first few courses produced in knitting a welt in the manner illustrated in Figs. 1 to 8, and Fig. 11 is a similar View illustrating another method of beginning the formation of the hem or welt.

In making stockings upon ordinary circular knitting machines it is customary to finish the stocking at the top by turning in a hem or welt and sewing the inturned edge thereof to the leg portion of the stocking, an operation which must be performed with great care and which is consequently expensive, while, at the best, the turned welt or hem produced thereby is unsatisfactory.

Another plan has been to knit a certain length of web upon the needles and then to turn back the edge of this Web and run the edge course of stitches onto the needles of the machine, which retained the last course produced, and then to draw the stitches for the next course through the two courses of stitches then upon the needles.

\Vhile this produces a satisfactory welt, the operation of running-on the end course of expensive one, and for this reason this method of forming turned welts has not met with favor,

In Letters Patent No. 864,433, dated August 27, 1907, I described a method whereby a turned 'welt or hem could be formed by the operation of the machine upon which the fabric was knitted, this operation being performed without the necessity of transferring stitches by hand and consisting in first forming a setting-up course upon two sets of needles, then knitting a length of web for the hem or welt upon one set of needles and permitting it to hang down fromthe other or inoperative set of needles, which retained the settingup loops originally formed upon them, and then, by a certain operation of the two sets of needles, transferring stitches of this web to the operative set of needles and freeing the web from the other set of needles, and then proceeding with the knitting of the leg tube upon the operative set of needles. 7

In carrying out my present invention I turn the welt or hem to the outside of the leg tube instead of to the inside of the same.

By this means I am enabled to impart a distinctive appearance to the welt at the top of the stocking, since I expose on the outside of the welt that face of the web which is usually on the inside of the knitted tube, this face presenting a dificrent appearance from that of the outer face of the web, as is well recognized by those skilled in the art.

A more important result, however, of this reversal in the usual method of forming'the welt, is that I am enabled to roduce it upon an ordinary knitting machine having but a single set of needles and thereby materially simplify and chea en the operation.

The machine may be 0 any of the usual types of circular knitting machine but is preferably one of that class intended for the production of tubes with seamless heel and toe pockets thereon, so that the leg, heel, footand toe of the stocking can 'be knit-ted. by one continuous operation. The machine is also equipped with web holders and in carrying out my invention in its simplest form, these web holders may be constructed and may operate, as usual. In starting to knit a stocking at the top of the leg, the yarn is first fed to all of the needles but as soon as one course of yarn has been laid in the books of the needles, every other needle (say, for instance, the even numbered needles) is retired from action but caused to retain the loop of the initial course of yarn originally laid in this hook, the desired number of courses for the welt being then knitted upon the remaining (or odd numbered) needles, and the edge of this strip of fabric being confined to the even numbered needles by reason of the retention of the initial loops upon the latter. When the desired number of courses of stitches for the welt has thus been knitted upon the odd numbered needles, the even numbered needles are again brought into action, and, in

drawing their first stitches, cast oil the initial loops which were formed upon them, these loops being caught and held by said freshly drawn stitches. The knitting of the tubular web for the leg of the stocking upon all of the needles is then proceeded with, the edge of the welt strip being integrally united to said leg tube by reason of the loops initially formed upon the even numbered needles.

If a relatively long welt is desired, the loop-retaining needles are retired from action while retracted so that the sinker Wales lying between the needle wales subsequently formed upon the odd numbered needles can pass over the retracted hooks of the even numbered needles and thus permit of the formation of a Web of any desired length. If, however, only a short, bunchy welt is re- ,quired, the loop-retaining needles may be retired from action while in a projected position, so that the sinker wales of the subsequently produced welt-lug courses will all be caught and retained by said needles, and will be cast ofl as a unit when the formation of the welt has been completed and the stitches for the first course of the leg tube are being drawn. A welt of this character, however, has the objection that it contains only half as many needle wales as are contained in the leg tube, and I therefore pre fer, in carrying out my invention, to proceed in the following manner in order to produce a welt having as many wales as there are in the leg tube. After laying the initial course of yarn in the hooks of all of the needles, I so act upon the loops of yarn carried by every other needle (say the even numbered needles) as to prevent said loops from beingcast fromsaid needles. by the subsequent knitting movements of the latter, for instance, I lower the loops on the needles to such an extent that the retraction of the needles sufficient to cast ofi the subsequently applied loops of yarn will not cast off the initial loops, which thus remain upon the stems of the needles until it is desired to cast them ofi", whereupon the restraining odd numbered needles, and y the loops of I yarn originally applied to the even numbered needles, and then placed under restraint thereon, so that on knitting the next course, stitches x will be drawn through the loops m, but fresh loops y will beformed on the needles which originally received the loops 3 the latter being retained on the needles for the purpose of subsequently uniting the edge of the welt to the leg of the stocking.

A simple method of lowering the initial loops y upon their needles is toprovide a set of web holders, every other one of which is operable at a certain time independently of the intervening ones, each of these specially operable Web holders 8, after the first course of the knitting yarn has been laid in the hook of its corresponding needle, being first withdrawn, as shown in Fig. 2, and then advanced, as shown in Fig. 3, so that a beveled forward face of the web holder may engage the yarn, depress the same and cause it to pass under the web holder, as shown in Fig. 3, the subsequent normal movements of the web holder not being sufficient to free the yarn from this restraint. After having been thus abnormally withdrawn, and then projected again, the web holders 8 act normally, and, in receiving the yarn for the second course the odd numbered needles will be operated so as to draw stitches w of said yarn through the loops w already upon these needles, while the even numbered needles will be operated so as to draw the new loops 3 as in Fig. .4, and in knitted and when the desired length of web for the welt has been'produced, as shown in Fig. 5, the web holders 8 will be again withdrawn to an abnormal extent and the initial loops 3/ upon the even numbered needles will be permitted to rise, as shown in Fig. 6, so that, in drawing the next course of stitches, these initial loops, as well as the loops last drawn by these needles, will be cast off, as shown in Fig. 7, the knitting of the leg tube being then proceeded with and the edge of the hem or welt being integrally united to said leg tube by means of said initial loops,

as shown in Fig. '8. If the pull of the web is not suflicient to insure the rise of the initial loops 3 upon the loop-retaining needles, when the web holders 8 have been withdrawn so as to release said loops, suitable lifting means may be employed. for effecting such rise.

The operation above described is as carried out in connection with a stocking in which the knitting begins at the top of the leg and progresses toward the toe, but there is another type of stocking in which a reverse method of knitting is adopted, that is to say, the knitting begins at the toe and progresses from the toe toward the top. In knitting a stocking of-this type I with hold the stitches upon every other needle when that point in the knitting has arrived where the welt is to be formed, and then proceed with the knitting upon all of the needles to form a band or strip of the desired length for the hem or welt, after which the restrained stitches are released and are cast off with the stitches already upon the needles in drawing the stitches for the next sion of this protective strip w as shown in Fig. 9, in order to insure that any raveling back of the stitches which may be likely to take place will not reach the point of union between the main web and the turned edge of the welt.

The knititng operations described inconnection with Figs. 2 to 8 produce an out turned welt which is united to the leg web only at every other wale, but a welt which is united to each wale of the web may be produced by restraining stitches upon the needles in successive courses, for instance, referring to Fig. 11, the initial loops y upon the even numbered needles may be restrained in the -manner before set forth, and, after the formation of the stitches w upon the odd numbered needles, the same may be restrained in like manner, so that in. the third course loops of will be formed upon the odd numbered needles while stitches 3 are being drawn upon the even numbered needles, the loops 3 and stitches w beingcast off simultaneously onto the stitches which constitute the first course of the leg web in order to unite every wale of the welt to said leg web. In this case it maybe necessary to tuck for several courses on the last of the even numbered needles, as shown for instance at w in Fig. .11,- in order to insure a proper start for the stitches upon the adj oimng odd numbered needles.

My invention, although intended especially for use in knittin seamless tubular webs, is not necessarily limited thereto, but is applicable also, to tubes composed of flat webs folded and having their meeting edges secured together.

The term loops as used in certain of my claims is intended as a generic term to include either initial loops applied to the needles, or stitches formed by drawing loops of yarn through previously formed loops or stitches.

By turning the welt outwardly a much smoother welt can be produced than when said welt is turned inwardly as usual, since the natural tendency of the knitted web is to curl outwardly. A stocking havin an outturned welt can, moreover, be boar ed more efiectively and with less labor than a stocking having an inturned welt, since the straightening and smoothing of the latter upon the board are rendered diflicult because, owing to the fact that the welt has been turned in a direction contrary to its natural direction of curl, it is very difiicult to cause the hem to assume a straight line at the top or fold, and, in consequence, present stockings which are provided with a hem at the top are almost invariably marred by the presence of folds or tucks in the web of which the welt is composed, these folds or tucks being permanently set in the web by the heat and pressure to which the wet or damp stockings are subjected after being boarded.
