SHEET 2 OF 3 IN VE N 70/? ROY 0. FA IGENBAUM A TTORNEY INTURNED WELT THE INVENTION The present invention relates generally to the art of knitting and more particularly to tubular inturned welt structures formed of circularly knit multiple course spiral fabric, such as the inturned welts of ladies circularly knit sheet hosiery, and to a method and machine for making the same.

In the manufacture of inturned welts of the prior art on a circle of latch needles and on a circle of transfer jacks associated with the needles, as set forth in the basic Scott US. Pat. No. 1,282,958 on the subject, the welt starting courses of suitable yarn are first made upon the needles with bights of the yarn, of one of the courses, being laid upon the transfer jacks and thereafter a sufficient length of fabric for the welt is knit upon the needles. Then, the bights of yarn previously laid upon the transfer jacks and which may also be referred to as loops of yarn, are transferred from the transfer jacks to the needles afterwhich knitting continues upon the needles thereby to close and to form the inturned welt. The transfer of the loops from the transfer jacks to the needles is done at the single feed of the machine and the transferred loops appear in a single course of the fabric which is known as the transfer course.

The above set forth mode of operation may be performed upon single feed, and upon multiple feed, circular hosiery knitting machines to provide the inturned welts for hose. When single feed machines are used to knit the hose, as in the said Scott Patent, the fabric courses made thereon are of single course spiral formation and accordingly the ends of the transfer course are not spaced by any other courses. However, when multiple feed machines are used to knit the hose, the fabric courses made thereon are of multiple course spiral formation and, with the transfer of the loops still made at a single one of the machine feeds, the ends of the transfer course are spaced by a number of courses equal to the number of the multiple feeds less one. Thus, in such inturned welts made upon multiple feed machines, there is a walewise extending offset, or gap, between the start of, and the end of, the transfer course, and the size of such offset between the ends of the transfer course depends upon the number of feeds being used in the machine making the welt.

When machines having relatively few feeds are used to make inturned welt hosiery, the offset at the ends of the single feed transfer course is relatively unobjectionable, however, with the use of machines having relatively large numbers of feeds thereon, the number of which may be up to twelve, the resulting offset at the ends of the single feed transfer course is of such extent as not only to be objectionable in appearance but also to cause an undesirable strain to be placed upon, and to elongate the transfer loops and their associated body yarn stitches in the vicinity of the end of the transfer course when the welt is subjected to the walewise extending strain which is present therein during the time the hosiery is being worn.

It is, accordingly, the primary object of the present invention to overcome the above set forth undesirable characteristics of the prior art transfer course of inturned welts formed of circularly knit multiple course spiral fabric, and to do this by the provisionof a noncontinuous or split transfer course to close the welt, and wherein the transfer loops of the separate segments of the split transfer course are transferred to, and are secured, in spaced courses of the multiple course fabric.

It is also an object of the present invention to provide means and a method for making an inturned welt upon the needles and the transfer jacks of a multiple feed circular knitting machine wherein the placing of the transfer loops upon the transfer jacks takes place at one feed of the machine and wherein the transferring of the transfer loops from the transfer jacks to the needles takes place at a plurality of the feeds of the machine.

With the above and other objects in view which will become apparent from the following detailed description of a preferred embodiment of the invention shown in the accompanying drawings, the present invention resides in the improved welt structure which is particularly useful in, but is not limited to, ladies sheer hosiery, and in the machine and method for making the same, as illustrated and as hereinafter particularly pointed out in the appended claims.

FIG. 6 is a schematic stitch diagram of the hose fabric as it appears in a walewise extending section thereof taken at the start of one of its split transfer courses.

FIG. 7 is a similar view to FIG. 6 as taken at the end of the split transfer course.

FIG. 8 is a schematic plan view showing a circle of needles in an eight feed circular knitting machine upon which the present invention may be carried out.

FIG. 9 is a schematic view of part of the needle cylinder and of the transfer dial of the multiple feed circular knitting machine being used and showing the relationship of the needles and transfer jacks therein during the start of the welt formation.

FIG. 10 is a view similar to FIG. 9 showing the relationship of the needles and transfer jacks during the closing of the welt formation.

FIG. 11 is a schematic plan view of the transfer jack operating cams in the dial cap by means of which the transfer jacks are actuated.

FIG. 12 is a schematic plan view of the full circle of transfer jacks showing the relative disposition of their high and their low operating butts.

The present invention has been shown, by way of example only, as being preformed upon an eight feed circular knitting machine of the type used for the knitting of ladies hosiery, however, it will be understood that the invention may also be carried out upon machines of this type which have a greater or a lesser number of multiple feeds, and may also be carried out upon other types of multiple feed circular knitting machines. Accordingly, the split transfer course of the present invention is shown as being incorporated, by way of example only, in an inturned welt made of eight course spiral fabric, and it will be understood that the present invention may also be incorporated in inturned welts made of other multiple course spiral fabrics.

There is shown in FIG. 1 a circularly knit ladies hose having a two ply tubular inturned welt 11 at the top thereof, the welt 11 having therein the split transfer closing course of the present invention, the pair of noncontinuous arc-shaped segments of which are indicated at 12 and at 13, the fabric of the welt and of at least the adjoining portion of the leg being of eight course spiral formation. The leg and foot of the hose may be made in any desired manner and may be of any desired formation.

As appears in FIG. 2, each of the split segments 12 and 13 of the split transfer course extends half way around the welt on opposite sides thereof along separate inclined lines which represent corresponding portions of spaced parallel courses, in this case, a first and a fifth course of the eight course spiral fabric. It follows then that the courses containing the transfer loops of the segments 12 and 13 are spaced by three courses of fabric and, accordingly, at the offset between ends 1211 and 13b (and 13a and 12b) of the segments, there is a gap of only three courses. In contrast therewith, in the prior art, welt 14, FIG. 3, made of similar eight course spiral fabric, at the offset between ends 15a and 15b transfer course 15, there is a gap of seven courses.

A comparison of the relative sizes of the transfer loops 15c and 15d at the ends of the transfer course 15 of the prior art. FIG. 5, and of the transfer loops 12c and 130 at the ends of the split transfer courses l2 and 13 of the present invention, FIG. 4, shows that while the transfer loops 15c and 12c, at the start of the transfer course 15 and of the segment 12 respectively, are relatively small and are of substantially the same size, the transfer loops 15d and 13c, at the end of the transfer course 15 and of the segment 13 respectively, are relatively large and differ greatly in size. This difference in size is due to the gap of seven courses l5e of body fabric between the ends of the transfer course 15 containing the transfer loops 15c and 15d, and the gap of only three courses 12d of body fabric between the ends of the split transfer courses l2 and 13, the body fabric in both FIGS. 4 and 5 being of similar eight course spiral formation. Transfer loops 15d are longer than transfer loops 15c due to the eight course spiral of the transfer course and, similarly, the transfer loops 13c are longer than the transfer loops 12c due to the four course spiral of the split transfer courses.

As set forth in the said Scott Patent, the first two courses made on the machine form a starting selvage for the welt wherein the yarn is taken by the odd numbered needles only in the first course with the even numbered needles in their welt position and wherein the yarn is taken by all the needles in the second course. In the third course the yarn is knit by the odd numbered needles only, with the even numbered needles again in their welt position while retaining thereon the yarn loops of the second course and at the same time bights or loops of the yarn are laid across the hooks of the transfer jacks which have been projected radially outwardly above the lowered even numbered needles. The transfer jacks are withdrawn after one course of loops have been laid thereon and thereafter, for the fourth and the following course of the welt, knitting takes place upon all of the needles during which the loops are retained upon the transfer jacks. After a suitable length of fabric for the welt has been knit, the transfer jacks are projected radially outwardly above the even numbered needles which then come up inside the loops on the transfer jacks and remove the loops from the latter as they are moved radially inwardly. In so doing, the transfer loops are placed on the shanks of the even numbered needles along with the stitches already thereon, so that stitches of the next course of knitting are drawn by the even numbered needles through both the transferred loops and the stitches on their shanks, thereby to interlock the said transfer loops and the said stitches together in a closing transfer course of the welt.

While the method set forth in the said Scott Patent is carried out upon a single feed machine, it may also be carried out upon multiple feed machines. In a single feed machine, the method steps used for the formation of the first three starting courses of the welt are performed during each of three revolutions of the machine at the single feed thereof, whereas in a multiple feed machine the same method steps to achieve the same result, are preferably performed at each of three feeds of the machine during a single revolution thereof. Thus, in the eight feed machine presently being used, as shown schematically in FIG. 8, the first and second courses forming the starting selvage for the welt are preferably made at feeds 1 and 3 thereof, while the third course, in which the transfer loops are laid on the transferjacks, is preferably made at feed 5.

This takes care of the conventional welt starting courses after which the next several following courses of the welt fabric in the presently used machine are made on selected feeds and in a manner most convenient to the structure of the machine, itself. Accordingly, the fourth course is knit upon feed 7 while the feeds 2, 4, 6 and 8 remain idle. For the next revolution of the machine, the next four courses are knit upon all the needles of the machine at the feeds 1, 3, 5 and 7, while the feeds 2, 4, 6 and 8 again remain idle. Thereafter, knitting continues upon all of the needles upon all eight feeds until a sufficient length of fabric has been made for the welt.

It is now time for the welt to be closed by transferring the transfer loops from the transfer jacks to the needles and, while this is done at a single feed in the prior art, whether such single feed is the only feed of the machine, as in the Scott Patent, or is one feed ofa multiple feed machine, in the present instance, the transferring of the loops to the needles is preferably done simultaneously at two feeds, namely, at feeds 5 and l, of the eight feed machine being employed. One-half of the transfer jacks are projected radially outwardly at feed 5 over one-half of the even numbered needles to transfer their loops thereto, while at the same time, the other half of the-transfer jacks are projected radially outwardly at feed 1 over the other half of the even numbered needles to transfer their loops thereto, thereby to provide the split transfer course containing the segments 12 and 13 thereof with each such segment extending 180 around and on opposite sidesof the welt. Thus, with one of the segmental transfer courses 12, 13, being made at the feed 5 while the other is made at the same time at feed 1, it follows that they are in courses which are spaced by three other fabric courses.

The relative operative disposition of the needles and transfer jacks at feeds 5 and 1 when the loops of yarn are placed upon the transfer jacks, is shown in FIG. 9; and FIG. 10 shows the relative operative disposition of the same parts when the loops are transferred from the transfer jacks to the needles. The disposition of needles and transfer jacks at feed 5 is indicated at the left-hand sides of FIGS. 9 and 10, while the disposition of needles and transfer jacks at feed 1 is indicated at the righthand sides thereof.

In FIGS. 9 and 10, a conventional needle cylinder 16 has radially movable conventional sinkers 17 associated therewith at its upper end, the sinkers being adapted to co-operate with a circle of conventional latch needles N which move vertically in slots in the needle cylinder. The needles N-1, in FIG. 9, are the odd numbered needles while the needles N-2, in FIG. 10, are the even numbered needles. Above cylinder 16 is a conventional transfer dial 18 provided with a circular series of radially extending grooves in which a circle of conventional transfer jacks 19 are adapted to slide when their operating butts 20 and 20a are actuated by the appropriate cams shown in FIG. 11. The butts 20 are the high butts and the butts 200 are the low butts, the high butt and the low butt transfer jacks being specially arranged as shown in FIG. 12. The transfer jacks 19 are disposed so as to be radially aligned with the even numbered needles N-2 and therefore are disposed between the odd numbered needles N-1. The transfer jacks, each of which is formed of separate halves of flexible material, FIG. 12, are shaped so as to have the hook shaped loop receiving ends 21, and having the halves thereof spread apart at 22,,adjacent the ends 21, to provide needle hook receiving openings therebetween. The circle of transfer jacks 19 is arranged in a novel manner, FIG. 12, so that a series of low butt jacks (shown at L), extends for approximately 110 degrees of the circle thereof, followed by a series of high butt jacks (shown at H), for approximately 70, followed by a series of low butt jacks similar to the series L (shown at L-l), and followed by a series of high buttjacks similar to the series H (shown at H-1).

In FIG. 11, the eight numbered feeds of the machine are shown in relation to the dial operating cams used to act upon the buttsof the transfer jacks to move the same radially of the needle cylinder. A jack projecting cam 23 and a jack retracting cam 24 are provided in the dial cap at feed 5 and a similar set of cams 23a and 24a is provided in the dial cap at feed 1. Also provided are the spaced concentric ring shaped plate cams 25 and 26 which define a pathway therebetween, within which the butts 20 and 20a travel in the direction of the arrow shown. The plate 25 is provided with a cut out cam face 25a following the cam 24. The cams 23, 24, are conventionally mounted and earns 23a and 24a are similarly mounted so as to be vertically movable into, and out of, operative relation to the jack butts under conventional pattern control, the movement being in a direction parallel to the axis of the needle cylinder, with the movement of the cams into operative position being carried out in two steps.

The set of cams 23a and 2411 at feed 1, in addition to the set of earns 23 and 24 at feed 5, permit the transferring of loops from the transfer jacks at both of these feeds at the same time. The disposition of the high and low butt transfer jacks permit both sets of operating cams 23, 24, and 23a, 24a, to be placed into operative position at the same time. It will be understood that the earns 23, 24, 23a, and 240, are partially lowered when the low butts 2012 are passing the cams, so that they are in position to first engage and move the leading high butts 20 of the series H and H-l, and that the cams are fully lowered while they are in engagement with the high butt jacks so as to engage and move the low butt jacks thereafter.

Only the cam 23 is lowered at feed 5 when the third course at the start of the welt is being made at this feed, the cam 23 acting to project the full circle of the transfer jacks 19 radially outwardly between the raised odd numbered needles N-l (as shown at the lefthand side of FIG. 9), to receive the loops of yarn of the third course in their hooks 21. It will be understood that the even numbered needles N-2 are in lowered welt position at this time. Thereafter, the transfer jacks are partially withdrawn by the action of cam face 25a on their butts. The position of the withdrawn jacks is shown at feed 1 at the right-hand side of FlG. 9. The cam 23 is left in operating position for one revolution of the needle cylinder.

The two sets of earns 23, 24, and 23a, 24a, are lowered into operative position at feeds 5 and 1 when the split transfer course 12, 13, is to be made to close the welt. The cams 23 and 23a project the transfer jacks radially outwardly above the even numbered needles N-2 which are then raised to extend through the openings 22 of the transfer jacks, FlG. l0, and thereafter the cams 24 and 24a fully withdraw the transfer jacks, as a result of which the loops of yarn on the hooks 21 are transferred to the needles N2. Onehalf of the transfer loops are transferred to one half of the needles N-2 at feed 5 and the other half of the transfer loops are transferred to the other half of the needles N-2 at feed I. The first transfer jacks to be projected at feeds 5 and l are the leading high butt-jacks of the two series H and H-1 thereof. Preferably, the earns 23, 24, and 23a, 24a, are left in operating position for approximately one-half revolution of the needle cylinder or until all of the transfer jacks have been projected and withdrawn. It is not necessary to otherwise divide the transfer jacks or the needles, for even if some of the transfer jacks are projected twice, no harm will be done, since their loops will have been removed therefrom when they are first projected, and the second projection will be an idle movement. During the transfer operation at feeds and 1, conventional knitting takes place at all of the feeds of the machine including the feeds 5 and 1 at which the knitting serves to join together the transfer loops and the stitches on the needles N-2. Continued knitting on all the feeds will then form the fabric of the stocking leg.

Stitch arrangements of courses of the welt made according to the above set forth method on an eight feed circular knitting machine are shown in FIGS. 6 and 7. The first four starting courses of the welt made on the feeds 1, 3, 5, and 7, are correspondingly indicated at la, 3a, 5a, and 7a of which the courses In and 3a comprise the selvage, the course 50 comprises the transfer loops, and the course 7a is the first course formed after the formation of the transfer loop course 5a. The individual courses of the eight course spiral body fabric of the welt made on the feeds 1 through 8, are correspondingly indicated at lb through 8b, at the lefthand side of FIGS. 6 and 7. The section of FIG. 6 is taken at the start of one of the like segmental transfer courses l2, 13, while the section of FIG. 7 is taken at the end thereof, the sections of FIGS. 6 and 7 being spaced by 180. It is due to this spacing of the sections of FIGS. 6 and 7 and to the spiral present in the eight course fabric, that the levels of similar courses shown in FIGS. 6 and 7 are offset by four courses; thus, course 8b in FIG. 6 (made at feed 8), is at the level of course 4b (made at feed 4) in FIG. 7, and so on. It will also be noted that while the transfer loops of course 5a are interlooped with, and are secured to, stitches of course 4b by the stitches of course 5b, in both FIGS. 6 and 7, to form one of the segmental transfer courses 12, 13, the transfer loops of course 5a in FIG. 7 are substantially longer than the corresponding transfer loops of course 5A in FIG. 6.

The transfer loops of course 5a gradually increase in size in each ofthe wales extending from its wale of FIG. 6 to its wale of FIG. 7. In FIG. 6, the walewise extent of the transfer loop of course 5a is such as to be substantially coextensive with the loops of course 4b, whereas in FIG. 6 the corresponding transfer loop of course 5a is long enough to extend over the loops of courses 8b, and 1b through 4b. The transfer course is the course in which transfer loops of course 50 and stitches of course 4b are joined together, and it will be seen that the level ofthe start of, FIG. 6, and of the end of, FIG. 7, the segmental transfer course is spaced by three courses of the fabric.

The transfer loops d at the end of the prior art transfer course 15 are initially elongated, so as to be substantially twice the length of the transfer loops 130 at the end of the segmental transfer course 13, so that when the welt is subjected to the walewise strain present therein during the time the hose is being worn, there is less give" in the transfer loops 15d (than in the loops 13c) and, accordingly, the resultant strain in the loops 15d is transmitted to the body yarn stitches of the fabric with which the loops 15d are interlooped. Accordingly, when the strain is sufficient, the described body yarn stitches of the prior art hose will be enlarged and may be permanently damaged. On the other hand, since the transfer loops of the present invention are initially much shorter, they will give more when subjected to strain and will thus be less likely to damage the body arn stitches.

It Wll e understood that the transfer of the loops from the transfer jacks to the needles may be made at more than a pair of the feeds of the machine, and that the feeds at which the transfer is made, need not be equally spaced around the machine.
