Definitions

  • Our invention relates to knitting machines and is directed to the production of knit fabric incorporating patterns or designs of all kinds, i. c.7 fancy fabrics in general.
  • Circular knitting machines with pattern mechanisms of the types heretofore used can bc adapted to produce a certain limited variety of regular patterns, but are incapable of producing, in a practical manner and for the every day purposes of commerce, a complicated design requiring more than a few dissimilar courses or rows of stitches to complete it.
  • Flat lmittingmachines have been used to produce more complicated designs, but the process with fiat machines is a slow and expensive one.

  • Fig. 10 is a further diagrammatic View showing the cams in a still more advanced position
  • Figs. 11 t0 14 are views showingseveral relative positions of the needles and yarn in the machine illustrated.
  • the invention is illustrated with reference to a circular knitting machine of standard type, the needles being of the latch type and the organization being such that thc design is distinguished from the background by the use of two different kinds of stitches, i. tuck and plain knit stitches.
  • the needle operation is that shown in Figs. 11 and 12.
  • the needle 11 is raised so high that the latch 13 clears the previous loop 11; the thread then laid against the needle indicated at 15. Fig. 11) and subsequently the ncedle is caused to descend.
  • the hooked end of the needle catches tln ⁇ thread (as shown in Fig. 1:2) and the further descent of the needle through the loop 14 of a. prior stitch.
  • oth loops are thus retained in the needle until such a time, during a subsequent operation, when the needle is elevated to the knitting position of Fig. 11. W'hen this occurs the following descent of the needle will cause the formation of at least a double loop 14, the original number 14 being allowed to slip over the top of the needle along with the thread or threads laid therein subsequently.
  • the master pattern mechanism is divided into a number of sections 28 (see Fig. 2) in the machine illustrated. There may be any number of these units or sections so long as they are in sntiicient number to assure the exercise of the pattern-control on each controllable needle in advance of each feed the action of which is intended to be modified by the pattern mechanism; this will be understood better after the operation is described.
  • The-sections are preferably distributed around the cylinder in order to bring the pattern mechanism into direct rclation with every controlled needle. being eqniangnlarly distributed if cvery needle, or clluiangnlarly distributed needles are to he controlled.
  • each section of this mechanism includes one of the belt-like sections lil into which the patternrontrolling element is divided.
  • These pattern .sections are perforated in accordance with the design to be knitted into the fabric as will also be understood from the matter hereafter.
  • Fig. l. thc needle cylinder is elongated or made .somewhat longer than usual, and a series of needle-liftine,r 'jacks 22 are arranged in the knitting cylinder grooves 23. one below cach of the needles to be controlled b v the pattern Vln effect.
  • these jacks are adapted to be lifted in part by the pattern mechanism and in part by a jack cam 24 (Fig. 8) which is also carried by the cam ring 31 which carries the needle cams 20 and 21.
  • Fig. 1() shows that the position of the lifting cam Q4 with respect t0 the projections or butts 25 of the jacks is such that if the jacks remain in their lowermost position they will not be engaged by the cam 24. but if any jack he given an initial upward movement by the pattern mechanism so as to bring its butt above the level of the point 26 of this cani then such jack will be raised by the cani and will lift the corresponding needle to knit position, i. e. its latch will be carried through the fabric.
  • the cam 24 is also a needle raising cam therefore.
  • the jacks Q2 are raised initially, i. e., above the point 26, by jack levers-27 ⁇ which are grouped into and form parts of the several pattern-control sections or units 28.
  • levers are placed substantially radial of the cylinder bed of the needles (Fig. 3), and their pivot bearings are supported in a fixed position with respect to the cylinder wherein the inner end of each lever extends into a slot in the needle cylinder and underneath a jack (Fig. 1). They may vary in length to correspond to the curvature of the needle cylinder (see Fig. 3). Above the outer ends of the jack levers 27 a rant 29 is provided in each of the sections 2S to operate the jack levers thereof (Figs. 1, 3, 4 and 5). These rams are vertically controlled by the cam 3() (Figs. 5, 8.
  • the slots 38 therein permit the selector levers to move longitudinally into and out of connectioncompleting position underneath the ram, as well as turn on their fnlcrums or transverse supporting pins 37, and each one is under the control of a spring 39 which normally holds its selector retracted from connectiont-ompleting position.
  • Iach selector 35 is further provided with a fcclcr which may he an integral linger 38. and the springs 39 are slightly inclined (Fig. 4) so as to also pnl? the feeler fingers down lightly toward Sil lill) Lenmar the pivoted platen roller 40, of which there is one in each unit, or section Q8.
  • rlhis platen roller 40 carries the portion 12 of the pattern-controlling element alloted to its section or unit 28, and is provided With -lon gitudinal grooves 41with which the perforations in the pattern-controlling element 12 are arranged to coincide as the platen is turned and the clement 1Q advanced and new to perforations are brought nnthrneath the 'group ot' teelers. Accordingly whenever a perforation in the pattern-controlling ele ment is presented to a feeler, that Ateeler is pulled down through it and into one of the 15 grooves 41. But whenever an unpert'orated portion of the pattern sheet 12 lies underneath a feeler, then that teeler is pressed lightly and only lightly, against. the pattern sheet and. the latter holds the feeler elevated zo and out of the cylinder groove.
  • the perforations or pattern calling agencies are arranged in rows crosswise of the pattern-controlling element as appears in Fig. (i. Likewise the 'fcclcrs are arranged 15 in a row crosswise of the pattern-controlling element as has appeared hereinbefore. Those selectors whose feelers 1lb* tind perforations in the pattern sheets 1Q and tall into the grooves 41 of the rollers are pushed forward successively by the successive turning of the platens, one after another, into connection-completing position underneath the rains 29.
  • the platens 40 are rotated successively, and step-by-step, by means of pawls 43 carried on the plungers 4l which are depressed successively by the cam 4.3;
  • This cam is also secured to the under side ofthe cam ring 31 (Fig. 1) along with the cani 30.

  • a latch 51 (Fig. 7) may be conveniently employed to facilitate the temporary removal of the platen 40 from its bearings which hold it (or rather hold its axis) in a fixed relation to the enacting grou i of feelers 38.
  • the platen is made readi y removable in order that new pattern sheets 12 may be substituted.
  • the end of the platen shaft opposite the ratchet 42 may be groovcd circuniterentially to receive the latch 51 which is hingedion the frame as shown. and which thus secures the platen in the machine.
  • Spring 55 will hold the plunger 44 against its cam 45.
  • rl ⁇ his spring 55 (sce Fig. 1) is carried in a bracket on the frame and the lower end et the plunger 44 rests upon it.
  • Springs 50 hold the rams 29 against the plunger-s 83 and these plungers against the cam 30.
  • the platen 40 is shown as a rotatable cylinder with grooves, but obviously a pattern support of a ditlerent type ma be employed to accomplish the saine 'resu ts. lVe have found it desirable, however, that the pattern sections 12 pass around supports which have lxed axes near the feelers, as in the construction shown, so that the attern sections 12 are simply pulled aroun like a belt, without oscillation. Furthermore, such a construction minimizes the wear of the pattern .sheets under the action of the feelers, and entails a longer life for the pattern sheets 12 than some other possible constructions, and is a construction,which is particularly well adapted for knitting machines as will be understood.
  • a suitable pattern sheet 12 is first prepared and a section placed on cach grooved platen 40; pins on the ends of the platens and corresponding holes 1n the edges of the section 12 cause the patterns 12 to advance with the turning of the platens.
  • the pattern-controlling pcrt'orations in the pattern controlling element l2 are placed in such a relation to these edge holes that the piutorations always fall above the platen grooves 41, as before indicated.
  • the di'tlercnt sect-ions of the pattern controlling element 12 may be perforated alike or differently for the various units 28 according to the design to be produced. Then the pattern sections 12 are in place, such teelers 38 as find perorations therein fall into grooves 41 of the various platen drums 40.
  • the cam ring 3l is now rotated by means of the bevelled pinion 47 which engages the circular rack 48 on the cam ring 31 (Fig.
  • the feeding cam 45 first turns one of the platen rollers 40 through approximately one-sixteenth of a revolution (since there are eight grooves 41 in each of the rollers 40 shown). This brings the parts of the said pattern unit 28 from the position shown in Fig. 1 to the position shown in Fig. 4. i. e., the wall of the groove Al1 of the turning platen has pushed against the feeler fingers that are within it and has pushed the corresponding selectors 3F into operative position between the ram Qland the jack levers 27.
  • the cani ring 31 now causes the ram 2f) of the same pattern section to be thrust downward by the cam 30 and brings the cam 45 into operation on the next succeeding section Q8.
  • the depression 2f the ram Q9 brings about the relation of parts shown in Fig. 5, i. e., the initial elevation of the corresponding iacks 2Q and the lifting of the fallen teelers 38 ont of the groove in the platen.
  • the platen is new given a further rotation of about one-sixteenth o'f a revolution (by cam 45) to bring a new groove 41 into feeler engaging position and the cams 45 and 30 then pass oil the plungers 44 and 33 -of the first mentioned section 28, the ram 29 rises, and the projected selectors 35 are returned by their springs to the selection-making position of Fig. 1.

  • All of the sections of the pattern mechanism are operated in this manner, successively, one after another, by the single set of cams illustrated, as the cam cylinder 31 continues to turn.
  • Thilo the cams and 3() are acting on one section 28, the needles opposite another section 28 are being acted on by the raising cam 24 and behind that other needles and jacks are being retracted, i. e. stitches are being completed, by the cams 21 and 54.
  • the operation of the machine therefore is a continuous one, needles being differentiated and set up by the pattern mechanism (in one portion of the machine) simultaneously with' the formation of stitches (in another portion of the machine), and the cylinder 31 turns without interruption.
  • the sections as a whole are operated progressively with respect to and in advance of each' pass or revolution of a feed, that is to say, 1n advance of each pass of a yann guide and its cooperating group of needle raising and stitch cams, such as has been described.
  • the feeler-to-needle couplings (by which I mean the mechanisms which eX- tend from the feelers to the cylinder, in the present instance the levers 35 and 27, and through the actuation of which the call of the pattern-controlling element is made effective on the stitch-forming elements) are operated progressively, round and round the machine, in advance of the feed, and thereby the control of the pattern element 12 is made manifest on each needle at a time when, for the moment, the respective needle is free of the needle actuating cams, and hence is free to receive a manifestation of the pattern control.
  • the machine By thus timing the action of the couplings with respect to the revolving cams the machine is permitted to operate continuously as aforesaid, the cam cylinder making rotation after rotation around the needle cylinder, all in one direction without stopping, each rotation adding a row or rows of stitches to the fabric.
  • the feelers 38 are also differentiated progressively, i. e. by reason of the progressive operation of the pattern sections.
  • the nature of the design Vor designs knitted by the machine as a whole depends on the arrangement or location of the perforations in the pattern sheet sections considered as a Whole, each row of perforations in the whole group of pattern sheet sei-tions representing (in the machine illustrated) a complete single course ⁇ ior row of stitches and may be unlike every other row and the design accordingly intricate.
  • feed it Will be understood that we refer to a yarn guide and the group of respectively associated members (customarily cams) which project and retract or otherwise actuate the stitch-forming elements in coordination with it; each complete individual pass or complete revolution ot' a feed about the machine axis adds a course or row of stitchcsto the fabric, some of which may he Welt stitches, however, and the place of the welt later further occu iied with a stitch of another variety by a su scquent passage of a feed, as will be understood.
  • our invention is not limited to thelifting of latch needles but it may be applied to other types of elements forming or assisting in the formation of the stitches. Furthermore it is not limited to the production of designs or Vl'ancy effects through the agency of knit and tuck stitches; inasmuch as it provides means for causing cach stitch forming element to act on yarn only as and when desired, the invention may be utilized for the production of fabrics and designs in numerous Ways that Will occur to those skilled in this art. Also it is not essential that each Jeeler coact with a single stitch-forming element although a feeler for every individual element produces a design having the clearest and most definite outline and affords the greatest possible degree of independent action to the stitch-forming elements, and hence the greatest Variety in design or patterns.

XNITTING MACHINE.
Application filed September 9, 1920. Serial No. 409,201.
Our invention relates to knitting machines and is directed to the production of knit fabric incorporating patterns or designs of all kinds, i. c.7 fancy fabrics in general.
Circular knitting machines with pattern mechanisms of the types heretofore used can bc adapted to produce a certain limited variety of regular patterns, but are incapable of producing, in a practical manner and for the every day purposes of commerce, a complicated design requiring more than a few dissimilar courses or rows of stitches to complete it. Flat lmittingmachines have been used to produce more complicated designs, but the process with fiat machines is a slow and expensive one. Therefore the production of brocadc-like patterns for eX ample, has been left exclusivelyv to the art of weaving where the construction of the pattern or design may be controlled effectively by a chain of perforated paper cards adapted to control the formation of every stitch, if desired, and in which art accordingly the design may be of any complexity and sub: stantially any size lengthwise of the cloth. Une ot the principal features of our invention is that we have discovered a manner of combining a paper pattern with a knitting machine that is wholly practical and highly economical, especially in connection with circular knittingr machines, and have thereby made it possible to produce readily, on circular knitting machines, the most intricate patterns and patterns which it has heretofore been impossible to produce practically on circular machines. The invention also involves other matters as hereinafter appears.
The Invention will bc best understood from a description of a machine embodyingr it. 1n the accinnpauying drawings:

Fig. 9 is a similar View showing the cams in a more advanced position with respect to the same pattern unit.
Fig. 10 is a further diagrammatic View showing the cams in a still more advanced position, and
Figs. 11 t0 14 are views showingseveral relative positions of the needles and yarn in the machine illustrated.
In these drawings the invention is illustrated with reference to a circular knitting machine of standard type, the needles being of the latch type and the organization being such that thc design is distinguished from the background by the use of two different kinds of stitches, i. tuck and plain knit stitches. In the production of knit stitches the needle operation is that shown in Figs. 11 and 12. At the beginning ofthe `formation of a new kuit stitch` the needle 11 is raised so high that the latch 13 clears the previous loop 11; the thread then laid against the needle indicated at 15. Fig. 11) and subsequently the ncedle is caused to descend. In its downward movement the hooked end of the needle catches tln` thread (as shown in Fig. 1:2) and the further descent of the needle through the loop 14 of a. prior stitch. causes this loop to close the latch 13 and thus permits this loop to slip over the top of the needle` thuslcaving a new loop 14, formed of the thread 15, hangmgon the needle when the needle rises again. The manner in which tuck stitches are made is illustrated in Figs. 13 and 14. In this case the needles are not raised quite high enough to enableV the end of the latch 13 to clear the prior loop 14 (Fig. 13). Upon the .descent of the needles from this tuck position. the hooked end of the needle 11 not only carries with it the new-iaid thread 15 but it also contains thc previous loop 14 (Fig. 14) since the old loop 14 is not now ermitted to slip over the top of the needle. oth loops are thus retained in the needle until such a time, during a subsequent operation, when the needle is elevated to the knitting position of Fig. 11. W'hen this occurs the following descent of the needle will cause the formation of at least a double loop 14, the original number 14 being allowed to slip over the top of the needle along with the thread or threads laid therein subsequently.
The principles of these stitches are well understood. In the machine of Figs. 1 to l0, there is the usual cylinder 10 vertically grooved for the reception of and constituting the bed of a bank or series of latch needles 11. A cam 20 is arranged to raise all the needles to tuck height as shown in Figs. 1 and 8. In addition a master pattern mechanism is provided through the agency of which any needle may be raised still higher, namely to the knit stitch position. Acoordingly` any one of the needles may at any one of its operations, according to the dictates of the pattern controlling element, function to produce either a knit stitch or a tuck stitch and the result of these diverse stitches will be the desired design in the tinal finished knitted fabric. The stitch cam 21.
retracts all the needles to their lowermost position (Fig. 14) to complete the stitches.
The master pattern mechanism is divided into a number of sections 28 (see Fig. 2) in the machine illustrated. There may be any number of these units or sections so long as they are in sntiicient number to assure the exercise of the pattern-control on each controllable needle in advance of each feed the action of which is intended to be modified by the pattern mechanism; this will be understood better after the operation is described. The-sections are preferably distributed around the cylinder in order to bring the pattern mechanism into direct rclation with every controlled needle. being eqniangnlarly distributed if cvery needle, or clluiangnlarly distributed needles are to he controlled. lt will bc observed that each section of this mechanism includes one of the belt-like sections lil into which the patternrontrolling element is divided. These pattern .sections are perforated in accordance with the design to be knitted into the fabric as will also be understood from the matter hereafter.
shown in Fig. l. thc needle cylinder is elongated or made .somewhat longer than usual, and a series of needle-liftine,r 'jacks 22 are arranged in the knitting cylinder grooves 23. one below cach of the needles to be controlled b v the pattern Vln effect. these arc extensions` of. or elongate the needles, and this permits the preferred placing of the pattcrn mechanisms outside of the needle cy memes? inder and underneath the machine bedplate as shown in Fig. 1. In the present instance, these jacks are adapted to be lifted in part by the pattern mechanism and in part by a jack cam 24 (Fig. 8) which is also carried by the cam ring 31 which carries the needle cams 20 and 21. Fig. 1() shows that the position of the lifting cam Q4 with respect t0 the projections or butts 25 of the jacks is such that if the jacks remain in their lowermost position they will not be engaged by the cam 24. but if any jack he given an initial upward movement by the pattern mechanism so as to bring its butt above the level of the point 26 of this cani then such jack will be raised by the cani and will lift the corresponding needle to knit position, i. e. its latch will be carried through the fabric. The cam 24 is also a needle raising cam therefore. The jacks Q2 are raised initially, i. e., above the point 26, by jack levers-27 `which are grouped into and form parts of the several pattern-control sections or units 28. These levers are placed substantially radial of the cylinder bed of the needles (Fig. 3), and their pivot bearings are supported in a fixed position with respect to the cylinder wherein the inner end of each lever extends into a slot in the needle cylinder and underneath a jack (Fig. 1). They may vary in length to correspond to the curvature of the needle cylinder (see Fig. 3). Above the outer ends of the jack levers 27 a rant 29 is provided in each of the sections 2S to operate the jack levers thereof (Figs. 1, 3, 4 and 5). These rams are vertically controlled by the cam 3() (Figs. 5, 8. 9 and l0) which is secured to the under face of the cam ring 31 and serves to depress the rams of all the sections 28 successively, or progressively around the machine, as the cam cylinder rotates. This cam engages the anti-friction rollers 32 on the upper ends of the plungers 33. The space between the outer ends of the jack levers 27 and the ram Q9 is sach however that the levers QT will not be directly engaged thereby, but the connection may be completed selectively by a series of selector levers 35 (Figs. 1, 3, 4. 5 and (i) of which there is one for each of the jack levers 2T. These selector levers 35 are also grouped into and form parts of the units Q8 (see Figs. 1 and The slots 38 therein permit the selector levers to move longitudinally into and out of connectioncompleting position underneath the ram, as well as turn on their fnlcrums or transverse supporting pins 37, and each one is under the control of a spring 39 which normally holds its selector retracted from connectiont-ompleting position. Iach selector 35 is further provided with a fcclcr which may he an integral linger 38. and the springs 39 are slightly inclined (Fig. 4) so as to also pnl? the feeler fingers down lightly toward Sil lill) Lenmar the pivoted platen roller 40, of which there is one in each unit, or section Q8. rlhis platen roller 40 carries the portion 12 of the pattern-controlling element alloted to its section or unit 28, and is provided With -lon gitudinal grooves 41with which the perforations in the pattern-controlling element 12 are arranged to coincide as the platen is turned and the clement 1Q advanced and new to perforations are brought nnthrneath the 'group ot' teelers. Accordingly whenever a perforation in the pattern-controlling ele ment is presented to a feeler, that Ateeler is pulled down through it and into one of the 15 grooves 41. But whenever an unpert'orated portion of the pattern sheet 12 lies underneath a feeler, then that teeler is pressed lightly and only lightly, against. the pattern sheet and. the latter holds the feeler elevated zo and out of the cylinder groove.
The perforations or pattern calling agencies are arranged in rows crosswise of the pattern-controlling element as appears in Fig. (i. Likewise the 'fcclcrs are arranged 15 in a row crosswise of the pattern-controlling element as has appeared hereinbefore. Those selectors whose feelers 1lb* tind perforations in the pattern sheets 1Q and tall into the grooves 41 of the rollers are pushed forward successively by the successive turning of the platens, one after another, into connection-completing position underneath the rains 29. To this end the platens 40 are rotated successively, and step-by-step, by means of pawls 43 carried on the plungers 4l which are depressed successively by the cam 4.3; This cam is also secured to the under side ofthe cam ring 31 (Fig. 1) along with the cani 30. lVhen one of the plungers 44 is moved downwardly bv the cani 45 its platen roller 4G is lirst rotated through a sutlicient are to cause the engaged selectors 85, that is to say, those whose feelers 3h have found perforations in the pattern sheet` and passed 45 downwards into a groove 41 ot that platen.
to be projected between the ends ot' the corresponding jack levers 2T and the ram Qt). The other selectors remain retracted. 'Ihus in Fig. l (compare with Figs. 4 and 5) the platen roller 4l) is shown at rest, and the feeler linger 38 of one of the selectors 35 is within one of the grooves 41 of the platen, while the corresponding linger ot' another selector is held above said groove by an impertorate portion of the local section 12 of the pattern-controlling element. The pawl 43 is thereupon pushed down by the cam l5 until the position shown in Fig. Al is reached. That selector 85 whose feeler linger 2in restno cd on an inlpertorate portion ol pattern 1:2 still remains in the position in which it was in Fig. l. i. e., retracted and inactive. 'l`bc other selector' 35 however whose lfcclcr linger S8 was engaged b v the groovt` 4l, has
moved forward until its upward projection 4G lies inward of the ram 29. The ram Q9 is now pushed down by the canl 30 (note the relation ot cam 30 to cani 45 in Fig. 8) and this brings the parts into the position shown in Fig. 5. In that ligure that or those selectors lo which have been moved forward into a position where they can be acted upon b v the ram 2U. have been pushed downwardly upon the corresponding jack levers, causing the roi-responding jacks 22 to he raised until their butts are now above the level of the point 2U on cam :24. This action (i. e.. the tipping or turning ofthe advanced selectors) has lifted the teelcr lingers 38 out ot the grooves 4l but the projections 4G of these selectors 35 (engaging the ram) teniporarily prevent the springs 39 from draw ing these selectors back. The cam 45 now 1depresses the plunger 43 still farther (note. the shape ot' this cani in Fig. 8,) thus bringing another groove 41 and row of perforations underneath the line of feeler fingers 3h. The cam il() now passes ott1 the roller '3:2 (and ram 45 otll the plunger 44) and the spring h() (Fig. 3) returns the ram to its upper position. This releases the projected selectors $55 of this pattern section and permits their spring 39 to draw them backward to the posi-tion of Fig. 1. in which position another selection of all the selectors of this group is made by its pattern section H; such teclers as now tind perforations below them tall into thc new groove 4l, or if the pat tern-controlling element is entirely impertorate. at that point, they all remain out of act`ou.
The parts having been gotten into the position shown in F ig. as before described, some ofthe jacks 22 are in elevated position as explained and presumably others have re mained in their normal or lower position. In other words, a relation is brought about such as is shown in Fig. 9. While the cam 2h) holds the rain 29 depressed and certain jarks elevated with their butts raised above the point :26 of the cam 24, the cam 24 comes into play and raises all raised jacks 22 still farther, and thus raising the corresponding needles l1 to the knitting position as shown in Fig. 10. From Figs. 9 and 10 it will be observed that the length of cani 30 and its relation to cam 24 are such that each ram 29 is held depressed until the cani Q4 has reached the last jack related to the respeet've ram. This is to assure that the butt of each raised jack is above the point 26 when the cani 24 reacties it. The jacks QE! which were not acted upon b v their jack levers .27 are. not attcctcd by thecam 24, and the needles ll corresponding to these latter jacks are only raised to the tuck position by the cam 20. ln the usual manner yarn is now laidin all the needles hy thel yarn guide of the same feed. that. is to say, by the yarn guide (shown in Fig. 1) coacting with the group of needle raising and stitch cams dis cussed, and thereafter the stitch cam 21 retract-s all the needles and thereby causes the formation of the appropriate stitches. The cam 54 restores all the jacks 22 to their normal or lower level.
A latch 51, (Fig. 7) may be conveniently employed to facilitate the temporary removal of the platen 40 from its bearings which hold it (or rather hold its axis) in a fixed relation to the enacting grou i of feelers 38. The platen is made readi y removable in order that new pattern sheets 12 may be substituted. The end of the platen shaft opposite the ratchet 42 may be groovcd circuniterentially to receive the latch 51 which is hingedion the frame as shown. and which thus secures the platen in the machine. By raising the latch 51 the shaft may be withdrawn, the platen taken out, and another pattern section 1Q substituted. Spring 55 will hold the plunger 44 against its cam 45. rl`his spring 55 (sce Fig. 1) is carried in a bracket on the frame and the lower end et the plunger 44 rests upon it. Springs 50 hold the rams 29 against the plunger-s 83 and these plungers against the cam 30.
By reference to Fi g. :2, it will be observed that the arrangement which has, been adopt` ed is such that while it allows each individual needle to be individually acted upon in a selected fashion, ample room between each two units 28 is provided for the operating mechanism, i. e. in this instance the plunger 44, pawl 43, and ratchet 452, the latch 51, bracket for spring 55, etc.
The platen 40 is shown as a rotatable cylinder with grooves, but obviously a pattern support of a ditlerent type ma be employed to accomplish the saine 'resu ts. lVe have found it desirable, however, that the pattern sections 12 pass around supports which have lxed axes near the feelers, as in the construction shown, so that the attern sections 12 are simply pulled aroun like a belt, without oscillation. Furthermore, such a construction minimizes the wear of the pattern .sheets under the action of the feelers, and entails a longer life for the pattern sheets 12 than some other possible constructions, and is a construction,which is particularly well adapted for knitting machines as will be understood.
The angular relation ot the various cams to each other around the axis of the needle cylinder, which determines the. order in which they act, is shown in part in Flg. 'l but more completely in Fig. ts'. Sun1mar1zing the operation of the machine as u whole with respect to the single' feed shown, its action is as follows: A suitable pattern sheet 12 is first prepared and a section placed on cach grooved platen 40; pins on the ends of the platens and corresponding holes 1n the edges of the section 12 cause the patterns 12 to advance with the turning of the platens. The pattern-controlling pcrt'orations in the pattern controlling element l2 are placed in such a relation to these edge holes that the piutorations always fall above the platen grooves 41, as before indicated. The di'tlercnt sect-ions of the pattern controlling element 12 may be perforated alike or differently for the various units 28 according to the design to be produced. Then the pattern sections 12 are in place, such teelers 38 as find perorations therein fall into grooves 41 of the various platen drums 40. As the cam ring 3l is now rotated by means of the bevelled pinion 47 which engages the circular rack 48 on the cam ring 31 (Fig. 2), the feeding cam 45 first turns one of the platen rollers 40 through approximately one-sixteenth of a revolution (since there are eight grooves 41 in each of the rollers 40 shown). This brings the parts of the said pattern unit 28 from the position shown in Fig. 1 to the position shown in Fig. 4. i. e., the wall of the groove Al1 of the turning platen has pushed against the feeler fingers that are within it and has pushed the corresponding selectors 3F into operative position between the ram Qland the jack levers 27. Continued turning of the cani ring 31 now causes the ram 2f) of the same pattern section to be thrust downward by the cam 30 and brings the cam 45 into operation on the next succeeding section Q8. In the first mentioned section 28 the depression 2f the ram Q9 brings about the relation of parts shown in Fig. 5, i. e., the initial elevation of the corresponding iacks 2Q and the lifting of the fallen teelers 38 ont of the groove in the platen. The platen is new given a further rotation of about one-sixteenth o'f a revolution (by cam 45) to bring a new groove 41 into feeler engaging position and the cams 45 and 30 then pass oil the plungers 44 and 33 -of the first mentioned section 28, the ram 29 rises, and the projected selectors 35 are returned by their springs to the selection-making position of Fig. 1. While tbe cam 30`is holding the ram 29 depressed in the first mentioned section 28, the cam ring 31 brings the cam Q4 to the jacks Q2 ot this part of the machine and such of those jacks 22 as have been raised by the levers 27 are now raised still higher by this .cam 24 and the corresponding needles are thereb raised to knit position, the other need es of this portion o the ymachine remaining in tuck position (Fig. 10) as before stated. The yarn guide now passes the needles corresponding to tlns tirs-t mentioned section 28, laying yarn in all of them and the raised jacks are1 then successively retracted by cam 54 while the needles are successively retracted by the stitch `cam 21 to form the appropriate stitches. that some of the needles of this portion of The result of these operations is.

the knitting machine (i. e., those whose selectors 35 found perforations in the pattern sheet 12) have produced knit stitches while the others havel made tuck stitches, all as directed by the pattern sheet. All of the sections of the pattern mechanism are operated in this manner, successively, one after another, by the single set of cams illustrated, as the cam cylinder 31 continues to turn. Thilo the cams and 3() are acting on one section 28, the needles opposite another section 28 are being acted on by the raising cam 24 and behind that other needles and jacks are being retracted, i. e. stitches are being completed, by the cams 21 and 54. The operation of the machine therefore is a continuous one, needles being differentiated and set up by the pattern mechanism (in one portion of the machine) simultaneously with' the formation of stitches (in another portion of the machine), and the cylinder 31 turns without interruption. In brief the sections as a whole are operated progressively with respect to and in advance of each' pass or revolution of a feed, that is to say, 1n advance of each pass of a yann guide and its cooperating group of needle raising and stitch cams, such as has been described. By this meansI the feeler-to-needle couplings (by which I mean the mechanisms which eX- tend from the feelers to the cylinder, in the present instance the levers 35 and 27, and through the actuation of which the call of the pattern-controlling element is made effective on the stitch-forming elements) are operated progressively, round and round the machine, in advance of the feed, and thereby the control of the pattern element 12 is made manifest on each needle at a time when, for the moment, the respective needle is free of the needle actuating cams, and hence is free to receive a manifestation of the pattern control. By thus timing the action of the couplings with respect to the revolving cams the machine is permitted to operate continuously as aforesaid, the cam cylinder making rotation after rotation around the needle cylinder, all in one direction without stopping, each rotation adding a row or rows of stitches to the fabric. In thc present instance the feelers 38 are also differentiated progressively, i. e. by reason of the progressive operation of the pattern sections. Of course the nature of the design Vor designs knitted by the machine as a whole depends on the arrangement or location of the perforations in the pattern sheet sections considered as a Whole, each row of perforations in the whole group of pattern sheet sei-tions representing (in the machine illustrated) a complete single course `ior row of stitches and may be unlike every other row and the design accordingly intricate.
It may now be observed that knitted fabries ilu-orporaiing designs of the greatest complexity and great length of repeat may be produced on a commercial basis, that is to say, reliably and comparatively cheaply, since the mechanism is such that the pattern-controlling element 12 may be made of paper or other similarly light, thin materials and since very large pattern elements of such materials are readily handled on or with the machine Without rendering the whole device impractical and generally noncommercial. Furthermore, pattern sheets of light thin materials like paper are easily and cheaply made, so that a manufacturer may oil'er a larger variety of fabrics to his customers, and may make up new designs at little expense. Patterns in the form of endless belts like each of the pattern sections 12 (see Fig. l) are especially adapted for the work. le have made these thin, paperlight, mechanically weak, materials available for pattern-controls by using mechanisms therewith which leave to the patterncontrolling elements l2 onl or substantially only, the bare function of directing the knitting processes, all the operations Subsc nent to the bare call of the pattern-contro ling element on the feelers, that is to say, the` operations which require the exertion ot any considerable force, being performed by other elements than the pattern element. Thus no considerable labor is imposed on the pattern and mechanically Weak or paper-light materials are made suitable. The foregoing is illustrated in the machine shown in the drawings where the pattern-controlling element 12 is required sim ly to support the light pressure of the fee ers 38, and all the operations subsequent to the call of the feclers (by the fcclers falling into the pattern perforations) are brought about by other elements of the device operating around the machine progressively in advance of the respective feed passes, beginning with thc platens successively pushing against the feclers that find perforations and thereby pushing the corresponding selectors forward. In toto, it will be observed that we have adapted principles of the well-known weaving Jacquard mechanism (as heretofore employed in the art of weaving) to knitting machines generally.
ly the term feed it Will be understood that we refer to a yarn guide and the group of respectively associated members (customarily cams) which project and retract or otherwise actuate the stitch-forming elements in coordination with it; each complete individual pass or complete revolution ot' a feed about the machine axis adds a course or row of stitchcsto the fabric, some of which may he Welt stitches, however, and the place of the welt later further occu iied with a stitch of another variety by a su scquent passage of a feed, as will be understood. There welt stitches are to be emlll ployed, the earn 20,- as a means raising the needles to tuck position, is omitted, with the result that no needle is raised to a yarnrecciving position except when its action is initiated by the pattern mechanism.
It will be observed that our invention is not limited to thelifting of latch needles but it may be applied to other types of elements forming or assisting in the formation of the stitches. Furthermore it is not limited to the production of designs or Vl'ancy effects through the agency of knit and tuck stitches; inasmuch as it provides means for causing cach stitch forming element to act on yarn only as and when desired, the invention may be utilized for the production of fabrics and designs in numerous Ways that Will occur to those skilled in this art. Also it is not essential that each Jeeler coact with a single stitch-forming element although a feeler for every individual element produces a design having the clearest and most definite outline and affords the greatest possible degree of independent action to the stitch-forming elements, and hence the greatest Variety in design or patterns. Where designs are to be equally producible throughout any and every part of the Width of the cloth the pattern-controlled stitch-forming elements must be distributed, that is to say, substantially regularly placed, throughout the Whoie of the needie bed, e. g. substantially equiangularly placed around thc needle cylinder of a circular machine. These and other modifications are Within the scope of our invention as appears from the appended claims.
