To all whom may concern;
I, VINCENT LOMEARXYE, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful improvements in Knitting Machines, of which the following is a full, clear, concise, and exact description.
This invention relates to knitting I113 chines and methods, and more particularly it relates to machines and methods, ttor knit ting mniti-color fabrics.
An object 'of-this inventionis to provide automatic n eans forilmitting a Inulti-color fabric in ivhich different portions of the fabric will he of different colors, the yarn which does not determine the color 0 the front of the cloth in any particular portion being carried along with the knitting but substantially concealed from the front of the fabric.
Another ohjectis to provide adjustable income in a knitting machine for varying the pattern of the fabric at any time desired.
Another object is to provide means for producing a predetermined variation in the rise and fall olthe needles of a knitting machine to cause desired. variations in the fabric.
Another object is'to provide for causing certain needles. to rise at particular times while allowing neighboring needles to remain in their lowest positions.
Another object is to nrovide a ias-chine for knitting a two-color tahric in which the yarn not in loops will be interlocked he.- hind and between the loops of the other yarn;
Still another object is to provide an improved method of knitting whereby the re,- suits outlined above may be accomplished.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
One form of this invention will he hereinafter described in detail. in connection with a circular knitting machine for knitting multi-color fabrics, In this machine the above objects are attained by providing four diil'erent kinds of needles in case the machine is for two-color knitting. \Two types have butts at. the same relative position along their shanks, but the butts i i one type are short and in the other, long. T two types are also characterized h long and short butts with the but .3
in relative position compared to the first two types. This enables the needles having butts at one height to be operated by cams independent of other coins for opcrating the needles having butts at the other height. A further distinction can he made by coins of diti'erent sizes for operating'only the needles with long butts or all the needles. The employment of four kinds of needles is or" course only one way in. which means may he provided for selectively-"op crating the needles in a predetermined manner.
In locating the needles in a circular knitting machine those places where it is desired that the fabric be one of the colors, the needles having butts of one height are placed, the long and the short butts being alternated. At the other places where the fabric is to be of the other color the needles having butts at the other height are placed,
he other 'the long and short butts being alternated Suitable cam surfaces are provided for bringing all of the needles for one color up to form loops when that color yarn is pass ing while when the other yarn is passing alternate ones of these needles are partially raised still keeping their latches open and keeping the last formed loop around both the needle and the open latch. After the yarn of the second color is hooked by these partially raised needles they are lowered again, vi hen the first yarn comes around again all of the needles for the first color are fully raised in turn to allow each old loop ofthe first. color and the alternately hooked. yarn of the second color to slip-ha low the latch so that when each of these needles is lowered the old loops and the hooked yarn of the second color will slip over the tops of the needles and be replaced by the newly formed loops. This results in the yarn of the second color being interlocked behind the loops of other color, there" by providing a closely knitted fabric which does not have any loose dangling loops on the back side of the fabric which in previous fabrics were sources of constant trouble because of the liability of their being.
snagged and the yarnhroken, thereby destroying the fabric. The yarn of the secondoolor inthe machine'of this invention is in 73. The odd numbered'need'les have {short the above manner locked between the loops butts as shown at 55and 58,. while the-even of'the first yarn without changing however numbered have long b-utts'as at 56 and 57. toanysubstantial degree the appearance of Forconvenicnce ii1 .'-ig..,1 .the longlmtts are 1 thefront-of the fabric. r l shown shaded while the short butts are-una The above described operation of the shaded in order togrca dily distinguishthe p needles for one color is repeated by other kinds of needles.

1,541,230 y is' Needle 1 will not be lifted by cam 61 but will remain with its butt along surface 71 similar to needles 3, 5, I, .9, etc. j The'needle 2 however with a long butt will be raised by cam 61 and will successively take positions similar to needles 4, 6, 8, etc. Needle 2 when raised by cam 61 will not be raised to its maximum top positionbut wilL be raised an amount sufiicient to allow the latch to open and have the loop surround both the shank and the latch but not raised far enough to allow the loop to slip over the end of the latch. The even numbered needles from 1 to 14 are then partially raised by cam 61 while the odd numbered ones re main in their lowermost positions.
Cum 62 will next strike the needles 1 to 14 and the cam is of sufficient width to lower both the long butt needles and short butt needles. However. since only the long buttneedles of 1 to 14 have been raised it follows that only the long butt needles of l to 14 will be lowered by cam 62. The revolving cylinder carrying the cams also supports and carries along with it the yarn carriers shown in detail in subsequent figures. Located just above cam 62 is the yarn carrier for black yarn 84 so that thelong butt needles of 1 to 1 1- will be lowered by cam 62 after black yarn 84 has been hooked by them. After the long butt needles of 1 to 1.4 are lowered by cam 62 they will be positioned the same as needles 26 to 29. The s ort butt needles 27 and 29 which were not aised by cam 61 nor lowered by cam 62 have their latches closed and contain inftheir closed latches loops ofthe white yarn previously made. The long butt, needles 26 and 28 which were pulled down by cam (32 have their latches still open but with each book containing both a loop of the white yarn and the straight portion of the black yarn within the hook and just above the White loop. The straight portion of the black yarn will lie on top of the short butt needles such as 27 and 29.
The next corn to ali'ect the needles having butts between surfaces 70 and .71 is cam 6:3 which is of such a width as to, "raise only the long butt needles to the position shown for needles 32 and 34. This is again only a partially raiscd condition suchas that 'produced by cam 61. above described. It will be noted that due tothe raising of the long butt needles by cam 63 the long butt needles each has (as shown atS l) its latch open I with the loop of white yarn as well as the straight part of the black yarn on the side of the needle adjacent the observer while the black yarn still remains above the closed latches of the short butt needles as shown The next cam to operate the needles having butts between surfaces 70 and 71. is cam .64 which isof such a thickness as to raise 4 both the short and long butt needles and to raise them to their maximum height. (lam 64 thereby puts the needles in positions similar to 43, 44, and since cam 64 in raisingthe long butt needles will allow the loop of unlooped black yarn to follow a Zig zag path in front of alternate needles and behind the remaining needles for a purpose described. later.
The next cam to operate the needles be tween surfaces 70 and 71 is cam 65 which will meet both the shortbutt and long butt needles in their uppermost positions with all latches open and will lower both types. Supported immediately above the cam 65 is the carrier for the white yarn 83 which carrier of course rotates with the ams. The yarn 83 will thcnbe caught by these needles as they are lowered, each latch will be closed by theformer loop bearing upwards against it and after each needle has reached near its lowermost position each old loop will slip over the closed latch of the needle and over the edge of the fixed cylinder so that when the needle has reached its lowermost position only the new loop is around the needle. Due to the fact ",that the black yarn is on one side of the long butt needles and the opposite side of the short butt needles the black yarn for each long butt needle will slip over the end of the needle and will lie beside the end of the old loop and across both parts of the new loop as will appear from the position of needle 54 in Fig. 2. The fabric shown in Fig. 2 is shown of course with the back side to the observer. For the loops formed by the long butt needles the black yarn just slipped over each needle by cam will lie entirely behind each loop formed thereby. For the short butt needles however the black yarn is already on the side of the needle opposite the observer so that when the old loop is slipped over a short butt ncedleby cam 65 and the white yarn is pulled through the old loop to form a new loop the blaclvyarn is caught and locked between the new and old loops as shown for example by the fabric opposite needle 53 of Fig. 2. The exact nature of thepath taken by the black yarn through the white yarn loops will be better understood by reference to Figs. 12 13 and 1 a cycle begun by the cam 61 so that the i3" needles after being lowered by cam d5- are white yarn and the blackyarn to slip bc 3' ready to be 'operat'ed again by earns. 61 2,
-'63," 6 4 and 65'. in the order named". to term 'a vnewi'o'w ofavhitef'yarn loops.
The above description has shown how the white yarn loops 'aref'formed +Tha't portion .of the fabric knitted by needles 1 to 14; 21
" to"3'- l, and 41 ,t o '54 will" be c jtnnp'osedlot 1 white yarn loops. The remainder of the fabric knitted by needles 1 5 to 2()' 35-t0 40 will be composed of black loops with the .-white yarn'--inter1ocked betWeenfthe black butts" and the-odd numbered needles baring short butts:
loops in a'ina iner-nowtobedescribed.
Needles-1 5 to a1 1d.35"t' ")'40 have butts adapted to operatebet'wee'n surfaces T2 and,
73, the even nlllllbfll'ed needleshaving long (311111.76 corresponds to cam 61 tot raise the lon'g butt needles. After this selective. rails ingtlie neeidles encounteream '17 whichco rresponds to canr62 to .cause the whfltezyarn to becaught by alternate needles withopen latches even-after ,they are lowered by cam 77- .Aft'er the passage otcam 7 7 needles 35 to 40would'1ook like needles 2- to with the yarns reversed of course. Gain 77 isof suflicient width to lower both the long butt. needles and the 'short'butt needles, but for the arrangement shown with cam 79 not 30.
operatingonly the long butt needles are lowered. After cam 77 has passed the next cam is'7ft of such'wwidth as to selectively raise only the long butt needles. For the particular arrangement shown this selectivity is not utilized since with cam 78 in the position shown both the long butt and short butt needles will befully raised thereby.
."l-heseneedlcs neat encounter cam 75 which corresponds to cam for catching the black yarn and, forming new loops, the white yarn being interlocked between the black loops in just .tbe same manner as described for the white loops. After cam is encountered-tho next cam is 70 and the above described cycle will be repeated as often as. desired.
It thus will be seen {that the needles 1 to 14,21 mat, and 41 to at will knit white loops with the black yarn on the back side of the fabric but interlocked in alternate loops, while needles 15 to '20 and 35 to 40 knit black loops with the white yarn 0n the backside of the :fabric'in'terlocked -in.alter-' and8l are'of coursemerely illustrative as the two ya'rns may be of any desired colors 3 ormay be of the same color but differing in. some other characteristic. Inrertain cases, 1 in fact, yarhso'f the same color and characteri'stics may be used, it being possible to 65 produce in :this manner a fabric wherein nate wales. 'lheresulting fabric therefore .has three; broad white stripes separated by ,two narrow black, stripes.
The 'aboye colors assumed for yarns 83 a striped effect; for example, is obtained .by

If howeye'rthes'e fourv cams". are adjusted so that cams 7S andtet are lowcred; out of operating range and canis- 66 and {79f are raised until operative the result will be'that cam 66 will raise to their uppermost positions both the short butt and long butt needles .whereby the needles will be raised suilicient to; allow'lthe old loops to slip over the endigof each'latch so that each needle will catch :the black yarn 84 and make new loops thereof. Cam 78 being low-- ered out of operative range will not raise the butts between surfaces 72 and 73 suifis loops of the black yar'n.; Only the long butt needles will be partially raised by cam 'T-t and cam 75 coming along will cause the cient to cause these needles to make new black yarn to be inerely:intertwined between them insteald of being looped. Cam 7 9 being raised will cause both the long andshort buttneedles to be raised to their uppermost position" whereby when they encounter cam -77 the needles ;--15 to 20 and to so will Gain form new loops of the white yarn. being lowered out of operative position will allowthe partially raised long butt needles to encountercam-65 whereby in a-manner heretofore explained the white yarn will be merely intertwined between the needles opcrating bet'weersurfaces 70 and 71..
This reversal of cams 64:, 66,79 and 7.8
therefore results in the blaclryarn being knitted where the ,white yarn formerly. was
and-the white yarn. lgnitted where the black was. After several rowshave been knitted in this manner- cams 64, 66, '38 and Y9 t e be replaced in the positions shown in Fig whereby the col scheme will be reversed again.- T-his'cha "ging of the four adjustable cams thereforeenables a fabric to be knitted re embling a checker, board in color mafia H In viewof theabore explanations itwill be apparentthatl'if it is desired toinake several ,white rows entirely around the fab 11C,' c'ams 64: and 79 should be raised-into desired around the-whole cloth :both cases operativepositi ons" while cams (3 6 and 78 should be inoperative. On the other hand, u if'an entirely black row or rows of loops is shown. A suitable stop member 112 limits' the upward movement. of the pivoted arm 'j105 In order to maintain the arm 105 'in {its uppermost" position after disc 4 108 hasbeen passed a spring member 113 is 'madej-fto ride over a curved surface 114 server; tospring outward the 114 adjacent stop 112 which is suitably supported .by revolving cylinder 91 from apoint not shown in the sectional view of Fig. 3.

This lowering -Anend viewof cam 79 is shown in" Fig.

Stop members 121 and 122' are provided 1 for the pivoted member 117 and this ilpii'otcd cam 66. This is 'for the rcason as shown in ppsition or lower member may be biased in eitheriitsjuppcr position b a springmemr such as member 113. s shown; in the drawing disc '1'1 8'has lowered pivotedmdmher 117 to its lower position whereby cam 79 is placed, in its-ino )erative position-1 Similar'arms ivoter may bepr'ovide on the rcvolving:=cylinder at points op site the other two adjustable cams 66 and IS, with this difference-however that the pivoted arm moved by f either disc 108 or should control; the lower cam 78 while the pivoted arm-moved by discs 118 und'119 should control the upper Fig. 1 thatcams 64 and 78 should be raised when cams 66 and 79 are lowered and cams 64-and 78 should be lowered when cams 66 and 7 9 are raised inordcr to get the checker board efl'cct. i
The manner in which the cylinder 91 may be revolved is not material to this invention ut may be accomplished in any of the ways known in the art. For example thelower side of base plate 92 may be provided with teeth which cooperate with a cog wheel to rotate the cylinder. The cop wheel (not shown) may be connected to a source of power such as determined links-, a plurality of cams such socket joint the revolving 'cylind 1'1 9,'while I Q or disc'shouid be pivoted-above theother'piw Lee-1.230

The manner in which the and may be raised or lowerec maybe understood from Fig. 4 which is a side view of the machine taken near :the cross section, of Fig. 2. The'lower end of support pivoted to a horizontal arm pivoted at 124 and at the end 0 posit'e the j pivot is adapted to be held'up by; latch-.7 125 which is pressed against the..arm' 128 -f by a spring 126. Whenever the latch-125 is released the arm 123 .falls down until'i'the stop 127; rests on plate-90,

Arm 128 on be mg i'taised wirll push latch-125 out far enough thereby giving; a variation nod to be held-by the latch in its upper position and arm 128 will remain in its lower position.
However as soon as wheel 136 has revolved to a sullicient extent that eam 131 .is operative to raise arm 128 and lower arm 123 as above described cams 64 and 78 will be inoperative and cams 66 and 79 will be operative. T his results in the needles having butts on the lower level knitting loops of the white yarn and those on the upper level knitting loops of the black yarn,--whercby a checkered client is produced Cams such as 130 and 131 may be suitably spaced along the chain 129 to give the reversals when de sired. Wheel 136 should preferably he geared to the mechanism driving the revolving cylinder 93' so that chain 129 moves along one link for a dciinitc number of complete revolutions of the cylinder 93.
At certain places along the chain it may be desired to have an attachment such as that shown in Fig. 9 which has no projection sullicient to raise either arm 12 5 or 128,but merely has a horizontal projection 13? extending away from the chain on the side opposite the observer. when it has reached the position shown for earn 130 in if" 4 will contact with a special control arm m8 and tend to raise the same. This control arm is supported by the pivoted latch 125 at one end and by a pivoted member lilt at the other end. The pin 13? coin in into contact with the projection 140 will push the latch back againstthe spring a suflicicut distance to allow that arm of the two arms i133 and 128 which is held up by latch 125 to fall down so that botharms 223 and 128 are in their lower positions and remain so until a cam surh as Hi0 or 131 comes along to raise one or the fllllll'.
From the above description it will be apparent that with both arms 121- and 128 raised all cams 64, 3.6:, 1 8 anri'ill Ni 1 be operated so that both types of needles knit not only black-loops but White loops as well.

The arrangement of the cam 101 of Fig. 3 should be such as to pull the sinkers in in this manner at erery knitting position as is welldmown in the art. The remaining parts of Fig. 11 are obvious from the previous descriptions. The end pieces 146 and 1 17 are attached to pivoted arms 148 and 14:9 for controlling respectively cams 78 and 36"in the same manner as pivoted arms 105 andill'f control the other two adjustable canis (S -l and 79. v

Figs. 1'2, 13 and 14 illustrate a fabric of a type which may he produccd by the present invention; Fig. 12 being a diagrammatic plan view of the fabric; Fig. 13' is a diagrammatic sectional view. and Fig. 14 an enlarged fragmentary view of the fabric. These figures illustrate a fabric composed of two yarns 150 and 151. the former of which is unshadcd and will be referred to as whitev yarn. and the latter of which is shaded and will be referred lo as black yarn. 'ih'c'fabric. as cxemplilicd in Fig. 12. compriscs a left-hand portion, in which the. black yarn is looped. and a right-hand portion, in which the white yarn is looped, three of the wales of the. black yarn being shown at n. b and c, and tour of the wales ot' the white yarn being shown at (l, o. f and 5 In this particular fabric, the unlooped portion of the white. yarn is interlocked with the black yarn in the ales a and 0. and is carried entirely to the rear of the black yarn in the wale Z1; while the unlooped tion of the black yarnis interlocked withthe loops oi the white yarn in the wales d and'f. and is carried entirely to the rear of the white yarn-in the wales c and g.
An arrangement of this type w'herein the unlooped portions ofthe y'arns are interlocked in alternate wales of the looped portions oi theotheryarns, gives a maximum of interlocking, while preventing the formation of dangling loops so frequently present on the inside of a two-color knitted fabric; the fabric knitted byithe present invention having no dangling loops, even at the point between the wales and d, wheret'he color ofthe front of the fabric changes. It will 1 .benoted that the fabric shown in Fig. 12 is ample, a fabric-of the somewhat different from the fabric shown in Fig. 2, in that there is an' interlock at each of the adjacent wales of different colors 0 and (l; whereas in the fabric shown in Fig. 2. therewould be an interlock only atone of :these wales, the next interlock occurring in a wale which would correspond to"the wale e. It will thus be obvious that fabrics having a variety of interlocking arrangements may be produced by the present invention, all of which are nevertheless substantially similar and capable of being readily produced by a machine of the typeillustrated. For 'cx character illustrated in Fig. 12 might beproduced by e series of needles arrangedas in-Fig. 1, except. that] the needles 20 and 40 would be omitted. Still another; arrangement might-be produced by the omission of the needles 21 and41.
It will be observed from Fig. let'that the black yarn is very tightly drawn so that very little thereof is visible from the front of that portion of the fabric fwh'ereintbc white yarn 'is looped. Thus there is prov duced a fabric wherein the unlooped portion does not substantially affect the character of the front of the fabric. It will, of course, be. obvious that there maybe produced by the present invention types, and fabrics in which the'yarns c0nstituting the samemay "be more or less tightly drawn according'to the type of fabric which it', is desired to produce.
It will be apparent from the above dcscription that the two color fabric is kniticd without the rcqnircmcnt of the 'so-callcd- I v 78 and 79 are as in the of the yarn; while being securely interlocked,

By means of the control. mechanism shown in these four figures cams 64 and 78 may be made operative for causing the upper level needles to form loops of yarn 83 and the lower level needles to form loops of yarn 84; or cams 79 and 66 operatiye to cause the upper level to loop yarn 84 and the lower level to loop yarn 83; or cams 61 and 7.) operative to cause the needles on both levels to knit loops of only yarn 83; or cams 66 and 78 operative whereby all the needles loop only yarn 84. a
Referring now to Fig. 17 the cams'64, 66,

The means for setting these cams however is somewhat different as-will now be dcscribed. lhe standard is similar to standard 1111of Fig. 3 except that three con-, trol discs 161, 162, and 163 are mounted. thereon. Standard 164 is also provided with three suitably spaced control discs 165, ]66, and 167.

This relation is such as to permit: (a) disc 163 to contact with the lower end of agen -L55; to 'ii'iiie tlim 6 operathence) disc 3.61 to contact with the upper end of arm 15s to render earn 66 inoperative; disc 186 to contact with the upper end of arm 159 to render cam T8 inoperative; and ((2') dis. 1 56 to contact with the lower end of arm 1:37 to render cam 75) operative. The positions taken by the tour adjustable cams a tter passing by the standards 160 and 16% in the positions shown in Fig. 18 will therefore result in the upper level needles knitting yarn 8i and the lower level needles knitting yarn 83.
Fig. 19 illustrates both of the standards 160 and 164C raised and caught by the latch aswould be the case after. the passage along the control chain of a cam such as that in Fig. With both standards raised ((1) disc 162 contacts with the upper end of arm 158 and the lower end of arm 156 whereby cam 6 is mace inoperative and cam tl-l is made operative: disc 166 contacts with the upper end of arm and the lower end of arm to make cum 7%) operative and cam 78 inoperative. lhis by referring to Fig. 1 makes both the upper and lower leve needles knit yarn S3 with yarn 8t being in terlocked on the back side.

It is obvious that with the cam control mechanism various color designs may be knitted without the requirement of the socalled yarn rhangers and without the formation of any danglinp loops. is of course understood that while only two yarn carriers are disclosed in Fig. 1 that as many inoperative while disc 167 is 'v arns,

The adjustable cams opposite each yarn carrier may then be set to have the upper level needles knit loops from all three white yarns and have the lower level needles knit loops only from the black yarn. Thiswillgive a pleasing efl'ect, since each black loop will be bigger than white loops and the three white yarns interlocked.
