This invention relates to knitting niachines for producing fabrics havlng varlations in stitch structure caused by transferring of loops, and more particularly the for -to transfer sinker wale loops to adjoining wales, and the object of the invention is to decrease the length of yarn drawn i such I transferred loops when making a fine gauge fabric.

The invention will be shown and described embodied in a Scott &-Williams' revolving cam cylinder knitting machine ada ted to transfer sinker wales to adjacent need e wales by the use of transfer jacks. It will be understood that the invention is also applicable to machines in which the needle cylinder revolves. The particular machine shown is adapted to knit plain fabric, fabric in which eyelets are made by all the jacks consecutively, and/or fabric in which patterned eyeaelet fabric is formed by means of jack selection.- According to this invention certain of the sinkersor'web holders in the machine are nebless and the lower edges of the trans fer jacks move at.a level below the tops of -.the remaining nebs.

When making ornamental openwork effects by means of transferring loops lateriallyto form eyelet holes' in the knitted web,

the yarn is laid over the to of jacks in addition to the sinkers in or er that those jacks may subsequently transfer those 100 s laterally. The resultin' fabric is shown 1n the Robert W. Scottatent No. 846,353, dated March 5,1907, and transfer jacks of this general type are shown in the patent to Robert -W. Scott No.

fabric of this type, it is necessary to reduce 846,430, dated March 5, 1907. When making fine-gauge nose of the transfer jack in such fine gauge machines may riot be too long'proportionater l to. other stitches, I roppse 'toj jassociate t e sinkers, needles an web holders inth'e novel manner hereinafter described,- In

this arranfi'jment the noseof each transfer jack lies 9. ve a sinkerf- 'which" has no neb or web holding nose above its knockingover or loop-measuring ledge. The jack is located down close to the knocking-over ledge of the sinker with its lower edge separated from the ledge by only enough space for the fabric to pass. Adjacent to the nebless sinker preferably is a sinker having the usual nose or neb. The parts are assembled referably in such a manner that the lateral nd of the transfer jack will bein sliding contact with the neb of the adjacent sinker. When it is desired to transfer a sinker wale laterally in one direction only, a single jack such as shown in Figure 5 ma be employed, but if it is desired to trans er that sinker wale laterally to the needles on both sides,

then a double transfer jack such as shown in Fi re may be employed.

ferring now to the general construction of the machine, the machine has a revolving central spindle upon which is mounted a stationary dial 19 fastened to a sleeve 18, and a stationary bedplate 16 on which is mounted the needle cylinder 17. The revolving elements "in the machine shown are the ear ring 21 and the cam cylinder revo ving therewith, the sinker cam cap 23 and the dial cam cap 24. The needle cylinder and dial are stationary. The sinkers or web holders 25, 26 are carried by the outside sinker ring 22 and the inside sinker ring 27 in the usual manner, the inside ring being supported by the upper end of the needle cylinder. The sinkers and needles are manipulated in the usual manner, the machine illustrated in the drawings being one in which sixteen courses are km't on 'each revolution of the machine. As already mentioned, the transfer 'acks can be controlled to produce plain fa ric without any eyelet holes .at all, or eyelet holes at every jack, or an eyelet pattern in which only certain jacks cause the making of eyelets. In the particular form of the invention shown in the drawings, means are provided for transferring sinker wale loops from a plurality of courses at the one time, two yarns being fed and drawn before the transfer is made.

- transfer Jacks have an operating butt 36, ashank 31'and -a lateral bend 32 which ex- Thesingle transfer jacks above referred to are designated generally by the numeral 28 and are carried on the dial verge 29 fastened on the upper face of the dial 19. These scribed presently. It might be well at this point to note that a transfer jack has three primary radial positions, as shown in Figure 4, namely, the withdrawn or out-of-action position shown at the, right of Figure 4,in which the outer end or nose 30 of the jack lies radially inward of the needles 37; the second position is with the end of the jack opposite the needles, the portion of the nose opposite the needles in this position being over the nebless sinkers 26this is the position in which the yarn is laid over the neb and the 100) is drawn; the third primary position 0 the jack is the one shown at the left of Figure 4, in which the sinker loop has been transferred to a osition above the adjacent needle wale an the portion of the transfer jack opposite the needle is the lateral bend 32, which lateral bend. lies on the oppositeeside of the needle in question from the tip of the transfer jack. In, this position the shoulder 34 of the jack is outside the circle of needles.

The mechanism for controlling the jacks will first be described and then the cam path for the needles will be described, the lettered lines of Figures 2 and 3 referring to corresponding points in the cam paths for the needles and jacks respectively. The cam path for the jacks includes fixed surfaces 41, 42, swivel cams 38, 40, 45, transfer cam 46 and pattern wheels generally designated by the reference characters 39 and 44 (Figure 3). Relatively to the cams the jacks move from left to right, as viewed in Figure 3, and the needles move from left to right, as viewed in Figure 2. When the jacks are at the point B they are extended fully to the transfer position shown at the left of Figure 4 and as they move past the point B 'they are pushed radially inward until by the time they reach point C they are out of action, with their tips slightly inside the circle of needles, as shown in the right-hand position of Figure 4. The next important move of the jacks is when they reach the swivel cam 38, the cam being shown in its retracted position. This swivel cam is used only when all the transfer jacks are to make eyelets inthe fabric, i. e., what is known as all-eyelet fabric. If all-eyelet fabric is being made the cam is turned radial- 1y outward, causing the jacks to start out at the point J and remain out until point U where the actual transfer begins." At the point L the butts of the jacks come opposite the first pattern wheel whose construction will be described in detail subsequently. The pattern wheel projects to laying position any jack which meets a tooth. If either all-eyelet fabric or a pattern eyelet fabric is to be made, the swivel cam 40, located just after the pattern wheel, will be retracted so as to permit the'jack butts 36, which have been travelling in contact with the outer cam edge 41 since leaving point J or which have just been projected radiall by the pattern wheel generally designate by'the number 39, to continue at that radial position in contact with the cam surface 42 which follows the swivel cam 40. The swivel cam 40 is solely for the purpose of pushing all the jacks radially inward in case any jacks have inadvertently moved to an outward position when no eyelets are being-made. The pattern wheel 39 and the swivel cam 38 act to press jacks outwardly only when so-called two-course eyelets are being formed the stitches of the first course being knit at point 0 just subsequent to the swivel cam 40. Immediatel after point 0, all transfer jacks not theretof ore pushed out to the'transfer position come in contact with a triagnular cam piece 43 which serves to insure" that1all 'zoj the transfer-jacks are ready to be selected by the second attern wheel 44 acting at point .Q. Pivotal ly mounted just after the second pattern wheel 44 is another'swi'vel cam 45 which insures ,that all jacks are retracted when a plain course is to be made. This swivel cam is thrown outwardly to idle position ifei ther an all-eyelet or. an eyelet-pattern'fabric is to be made. the jacks meet a transfer cam 46 which pushes all the jacks radially outward for transfer of the sinker wale groups. When A plain fabric is being made the transfer cam 46 can, if desired, be retracted to the position shown in dotted lines. After passing this transfer cam the jacks meet an inclined surface similar to the incline at point B and are pulled radially inward thus transferring their loops to the cylin er needles. At the end of that incline the jacks are out of ac tion in a position similar to that at point C and similar to the right-hand position shown in Figure 4. For the purpose of controlling the positions of thethree swivel cams 38, and 45, the cams are linked together by means of arms similar in function to an arm 47 which is connected to a circular ring 48 set in the to of the dial cam cap 24. This ring 48 is a a ted to be moved circumferentiallyrelative y to the dialcam cap when-' ever a change in positionof the swivel cams is needed. In the case of the swivel cams 40 and forming part of the outer edge of the cam path, each of those swivel cams is connected-to its arm 47 by a vertical pin '49 and the connections between the arms 47 and the ring 48 are swivelled by. means of a pin 50 playing in the slotin the end of each arm 47, the pin 50 projecting u wardly from the surface of the ring 48 (see 3). Swivel cam 38 -is also connected to the rin 48 by means of an arm 47' intermeshed wit ring 48 (see F i 3). These three swivel move simultaneously. This linkage is such At point U alligures 1 and a pin 49' on an extension 51 on the cams are there ore" linked together and" that all three cams are radially inward of the machine at the same time when plain fabric with no eyelet holes is to be made, the

swivel cam 38 being retractec lgout of contact with the butts of the jacks and the cams 40,

45 being radially inward into the paths of the butts so as to retract immediately any jackswhich may be selected by the pattern wheels 39 and 44. Their radially outermost, position is .the one in which all-eyelet fabric is produced and in this position the swivel cam 38 presses radially outward all transfer jacks while the swivel cams 40 and 45 are withdrawn out of the paths of the butts 36 of the jacks. When it is desired to produce, an eyelet pattern by means of the pattern wheels 39 and 44, the three swivel cams are in an intermediate or neutral osition in which the swivel cams allow the ]8.CkS to be selected by the patternwheels, carried out to take the yarn and to remain out until the transfer. The transfer cam 46i1 if desired,

can be left out permanently in t e operative 0 position shown by the sold lines in Figure 3 because unless the jacks have been pushed radially outward by the pattern wheels or the swlvel cams early enough to have yarn laid over them the pushing out of the jacks at the transfer point will not cause the making of eyelets. However, if desired, the transfer cam 46 can be made adjustable or retractable so as to withdraw the cam when plain fabric is to be made. The showing in Figure .3 constitutes one quarter of the entire dial cap.

Thepattern wheels 39, 44 are suspended from the dial cam cap 24 by means of a bracket 52 on which the central pins 53 of the two wheels are carried. These wheels each comprise a supporting plate 54, a cut pattern disk 55 mounted thereon and a threaded clamp or nut 56 holding the cut disk on the supportin plate. This cut disk" has teeth projecting rom the circumference thereof wherever it is desired to have an eyelet in the fabric and those teeth are of such a length that as the disk is revolving the teeth will contact with the butts 36 of the transfer jacks and push them out to the intermediate position shown in Figure 4 where the yarn being fed to the'needles will be laid over the nose of the transfer jack. The central pin 53 of each wheel projects from the bottom of the bracket 52, and fastened thereto by means of a countersunk disk and screw, is a gear wheel 57 meshing with an internal gear ring 58 held between the dial 19 and the dial verge 29 by means of the screw 33 which holds the dial and verge together. It will be obvious that as the dial cam cap 24 revolves about the stationary dial the gear wheel 57 will be revolved and thus cause-the pattern disk to turn, bringing selections for the transfer jacks into operative position successively.

Referring now to the cam ath for the drawn the jacks remain in their retrieved butts of the needles 37, the our knitting or withdrawn position as they Eggs pofints n 1e in points shown in the quarter section of the cam cylinder are designated by the letters D, J, O

needles are raised to clear their latches are designated by the letters B; G, M and R. The portion of the cam cylinder where the needles are lowered while the jacks are carrying their loops out for transfer from the loop laying position to the transfer pos1- tion lies between the points marked U and V and the needles are put up to take the transferred loops from the jacks beginning -to its extreme position in at point W, the actual transferbeing completed between the points B and C of the following quarter of the cam cylinder.

The construction of the machine having been set forth, its operation will now be described. We shall first assume that lain fabric is being knit without any eyelet oles in it. In this case the ring 48, will be pushed the direction of knitting, i. e., to the right in Figure 3, and the swivel cam 38 will be withdrawn from the paths of the butts 36 of the transfer point jacks while the swivel cams 40 and 45 are inserted into the paths of those butts, so that it will move radially inward any jacks WhlCh may be selected by the pattern wheel. If the transfer cam 46 at the-left hand of the section has not been withdrawn from o erative position all of the jacks will be r outward in transfer position at the point A and in this case the needles clearing at the B will come up beside the jacks, but by the time the elements have reached the point where the new yarn is being fed to the needles, the jacks will have been retracted. At the point D plain stitches have been drawn and are knit in,.and at the point G the latches of the needles which are just cleared have new yarn fed immediately and knit in to make the second course of plain d acks because that wheelis adapted to push stitches at point J. The jacks are not move" out at point J by the swivel cam 38 because that cam is the pattern wheel 39 at the point L any which may be selected by teeth on the pattern wheel disk will immediately thereafter be retracted at the point N before a yarn can be laid over them. At point 0 a third plain course is knit by the needles. At point Q, the jacks are passing the second pattern wheel.44 and some of t em may be selected to move radially .outward at this point. The needles clear their latches again at point B. but before any yarns can be laid over the noses of any jacks which may have been selected by the pattern wheel 44, the swivel cam 45 withdraws those jacks at point stitches is knit at point T. If the transfer cam 46.at the right hand of the uartei' section, as shown in Figure 3, has n withand .T. The points at which theially retracted, but as the jacks pas P S and the fourth course of plain.

U, V and W, but if the cam has again the jacks are pushed radially outward and remain there until clearing point B on the following quarter section of the cam segment, plain fabric resulting in either case because the jacks have no yarn on their noses.

When it is desired to make fabric with simultaneous transfer of two sinker wale loops on each jack, the operation of the machine is as follows: The ring 48 is moved to its extreme left position, as shown in Figure 3, having the effect of advancing the swivel cam 38 into the path of the butts of the transfer jacks and retracting swivel cams 40 and 45 out of the path of those butts. The transfer cams 46 at the beginning and end of-the quarter segment shown are in inserted position. The ,transfer jacks coming up to the point A have on; them two sinker wale loops each and the transfer cam 46 forces them out to the transfer position, as shown at the left of Figure 4 and as shown in Figure 6. Bythe time the transfer jacks reach the point B the needles have been raised to the clearing point so that they project within the sinker wale loop and when at point C the jacks are retrieved or retired Tadially inward out of action behind the cylinder needles, the needles take the sinker wale loops and the transfer is complete. A new yarn is then fed to the needles and at point D the transferred loops and the new yarn are all knit in. A plain course is then knit, the needles clearing at oint G and hitting at point J. "At point all the jacks are moved radially outward to their middle position where loops can be laid over them, but they come out too late to receive the yarn which is .knit in at the point J. The pattern wheel 39 at the point L does not cause any change of position of the pattern the jacks outwardly to the loop-laying osition and all the jacks are already in that osition. The swivel cam 40 being retracte the jacks pass that point without being moved. The yarn for the next or third course in the quarter se fed under the hooks of the needles lies'over the noses of the jacks, the needles having cleared at the needles knit their first course over the jacks but the. jacks remain out in their yarn-laying position and the machine continues its revolution past the second pattern wheel 44 and the second swivel cam 45, which are inefl'ective on the jacks for the same reasons that the first pattern wheel 39 and the first point M. At the point 0 the entasitis' at point T. Between the point T and the point U, the needles are raised and lowered again in order that the stitches thereon may open the latches and that the latches will not get inside the transferred loops. This avoids breaking of the transferred loop or the regular loop on the needle. Between the point U and the point'V the transfer cam 46 shown at the right of Figure 3forces all the transfer jacks out to the transfer position; and between point V and point W the needles are raised to take the transfer loops. The jacks are retrieved or withdrawn beginning at point B at the next uarter segment of the machine, as alrea y described with regard to points A, B and C at the beginning of the quarter segment. In this way a plurality of sinker wale loops have been accumulated and subsequently transferred simultaneously in the one course. i

If it is desired to have an eyelet pattern,

i. e, to make eyelet holes on certain jacks only, the two pattern wheels 39 and 44 are availed of to provide the necessary selec tion (Figure 3). In order not to nullify the action of those two pattern wheels the control ring 48 is moved circumferentially to its mid position, in which position the three swivel cams38, and 45 are all in a neutral position where none of them interferes with jacks which are at the out-ofaction or at the loo -laying position. When making this type 0 fabric the transfer cams 46 will of course be in their operative or outward position and the transfer and kniting in of the sinkerwale loops laid on the jacks in the previous quarter of the machine occur at points B, C and D, as in the case of the all-eyelet fabric above described. The knitting of the lain, course between. point G and oint J is also the same as heretofore. already mentioned, the swivel cam 38 is not inserted far enough to move the transfer 'acks whose butts are riding along the path 35 at the idle position, and as the butts of the jacks come opposite the first selecting wheel 39 certain of them are pushed radially outward by teeth on the pattern wheel to a position where their noses will underlie the yarn bein fed to the needles between the points and O. The sinker wale loops are therefore laid over the noses of those jacks only. The first course containing the selected sinker wale loops for transfer knitsat point 0.. At point Q the'selections for the second course containing the sinker wale loo 5 to be transferred are made on the secon pattern. wheel 44. At point B. the needles are raised to the clearing point; and at pdint T that second course isknit in. The needles are then raised to 0 en the latches as hretofore explained. hereafter the needles are drawn down again by the time they reach point duced.

U and at point U the jacks begin to move radially outward to the transfer Thispushing out of the jacks is com leted by the 'timethey .reach the point immediately the needles begin to rise so that they are up to take the transferloops by the time the elements reach point W. The

and

needles continue rising, as is the case between points A and B of the quarter segment sho wn in the/drawings, and at point D the jacks begin to retire as before. In

this way a selected two-course eyelet pattern is made. leaving out entirely the disk 55 of the first wheel 39, one-course eyelets can be pm- In knitting eyelet fabric of this. eneral character when fine-gauge fabric is Sesired, the size of the normal stitch becomes so small that it is impossible to draw a sinker wale over the nose of the transfer jack in t e ordinary eyelet machine, which It will be obvious that by will not be so slack as to be robbed and produce a general looseness of the fabric on either side of the eyelet. I have disc0vered that the relative size of the sinker wale loo drawn over the nose of the transfer jack can be made sufficiently small for finegauge fabrics to avoid this robbing and fproduce' the proper proportionate slze 0 an eyelet hole by locating the lower edge of the transfer ack at a level below the tops do'this I propose touse certain sinkers with nebs 61 and certain others without nebs.

I also prefer to locate my transfer jacks in such a manner that the lateral extensions thereof have a brushing contact with the sinkers having nebs thereon, and to have the line of the shank and the tip of the transfer jack directly above the nobless sinker, leaving merely sufiicient room for fabric to play thereunder. It will be noted that the jacks move with their low- 7 a transfer jacks located beside the nebs of the neb sinkers and in lateral contact therewith, makes it possible to knit eyelet'fabnc of a very I of stitch not otherwise pbtainabla,

fine gauge with a unifo m y of its be used in the transfer of a sinker Wale loop laterally in two directions at the one time onto theadjacent needle on each side, and in such case a jack such as shown in Figure 10 may be employed. This jack comprises two elements 59 and 59', such as shown in Figure 5, with the lateral bend in one formed in the opposite direction from the other, and in order to keep the two halves of the jack together in the same radial position at all times, the two halves are spotwelded togethor at the butts, as indicated in Figure 10 by the two dots 60 thereon, the two halves being shown as not otherwise fastened te-.

gether. The operation .of such a double transfer jack will beobvious in view of the description iven of the single jack and the patents to obert W. Scott Nos. 846,430, 846,431, both dated March 5, 1907, and 919,- 962, dated April 27, 1909.

If it is desired to control the groups of swivelcams in each uarter segment of the machine independentl y of the other groups the ring 48 is made'in four pieces-one for each quarter. Each piece then is shorter than its se cut, as indicated by the dotted line at the eft of Fi 3. This permits such control of the ring pieces that their changes occur at the same point in the fabric.
