a box unit containing a number of fingers, each finger controlling a diiferent yarn. In knitting the striped material, the relative position of such fingers was changed so that certain colored predetermined yarn was knitting while all the other colored yarns were held out of engagement of the needles; the position of such fingers being again changed depending upon the color desired to be knitted. A The different colored yarns which are not desired to be knitted are allowed to become wound around the central shaft of the knitting machine, such excess yam being cut from time to time. This has two chief disadvantages in that a large percentage of waste occursnand the number of feeds knitting is limited and the machine must be constantly watched by the operator, since the non-knitting yarn may become entangled with the knitted fabric.

Another method employed in the manufacture of a horizontal striped knitted fabric is to employ a multiple feed machine for different colored yarns in certain predetermined feeds, and the feeds containing particular yarns which are not positioning the needles in the non-knitting position, known as tuck o'r welt position and the yarn in such feeds are temporarily held and cut. The

-means to hold and cut is done by individual cut ting units located at each different colored yarn of the parts not functioning properly, at the sametime necessitating constant supervision by a skilled operator.

Instead of holding and cutting the yarn asin the paragraph previously described, the non-knitting yarn may be floated across the diameter of the circular knitting machine and a tensioning means is employed for absorbing the slack of such yarns. This is also undesirable, since the non-knitting yarn is twisted, forming a spiral, thus producing a certain amount of waste with the possibility of constant breakage of yarn and rig careful and constant watching by a skilled operator. The finishing of such fabric containing a twisted yarn spiral makes it exl0 ceedingly diflicult to finish such fabric to have i the stripes run horizontally.

Therefore, the object of my invention is to provide a simple and single cutting means upon a multiple feed circular knitting machine irrespective of the number of difierent colored yarn feeds.

said cutting means cutting the different colored yarns which are not desired to be knitted into the body of the fabric; the yarns so out are held until such yarnsare again desired to be knitted into the body of the fabric to create a predetermined colored horizontal stripe.

Another object of my invention is to provide new and novel type of fingers to; carry the yarn across the cutting means.

Another object or my invention is to provide a cutting means in the form of a circular knife for means to revolve said circular knife.

Another object of my invention is to provide a novel cam action to control means carrying yarn to cutting means for a circular knitting machine. I

desired to be knitted are taken out of action by my invent "Wide a novel gear arrangement mounted upon the central shaft of g, circular knitting machine, such gears having a direct relationto the number of feeds upon the circular knitting machine; the ratio between the driving gear and a cam gear being the same as the number of feeds upon the circular knitting machine is to one.

Another object of my invention isto provide stationary means in relation to the rotating frame of the knitting machine, such stationary means holding revolving cutting means.

Another object of my invention is to provide 'a novel mechanism for motivating the chain of links for controlling the changing mechanism for controlling the design of the fabric.

Another object is to provide anovel changing mechanism for disengaging the knitting yarn and for taking the feeds out of knitting action.

5 Another object is to provide a new andnovel ing the yarn carrying means.

the purpose of preventing holes being made inthe changing area or the point in the circular knitted fabric where the color change takes place.

Referring to Fig. :32, numeral 50 is the stationary part of a standard knitting machine to which is attached stationary cylinder I39 containing the usual needles and sinkers therein. A horizontally rotating gear base ME, having rigidly fixed thereon yarn table supporting posts I41, the usual needle actuating cams, rising cams Ill and stitch earns 93 (shown on Fig. 24), sections H5, yarn feeding mechanisms 86 and cams H which actuate chain mechanism (shown in Fig. 10). The gear base I48 is mounted in horizontal position-upon stationary framework 50 and is rotated in the standard manner by driving gear I48.

Yarn table 45'is attached to supporting posts "1 by shaft 35, which extends sufficiently far down so that the driving gear 52 is rigidly attached thereto, and the yarn cutting mechanism and its supporting framework is freely mounted thereon, as shown in Fig. 1. The rotation of gear base I48 rotates driving gear 52 because of Referring to Fig. 1, upon shaft 35 is .attached a stationary framework consisting of two framework plates 3'! and 38, which are spaced horizontally and parallel to each other by pipes 43 and H of equal length and through which threaded bolts are passed capped by nuts 46. Plates 3! and 38 are held upon the central shaft 35 by upper collar ll and lower collar 42 rigidly attached thereto. This construction prevents displacement of the framework from the horizontal position. The shaft 35 rotates freely in horizontal plates 31 and 38. The lower framework it housing 60 is is, attached to'horizontal framework plate 38. A cloth spreader 39, preferably made of wood,

is attached to the lower ends 'of the vertical about pivot pin 94 .Which is mounted upon plate eighth inch, the entire central framework is prevented from revolving with the rotating shaft 35 by the rollers 40. This construction comprising pipes 43 and-44 and rollers 40 maintains the framework in substantially rigid position, preventing displacement in any plane.

A horizontal driving gear 52 is firmly attached to the rotating shaft 35 between the rotating yarn table 45 and upper collar 4I. Driving gear 52 rotates an eccentric cam gear 53 which is mounted upon'cam gear bearing 54. Heating 54 consisting of several parts is rigidly fixed upon the stationary framework by the bolt passing through pipe 43 and' the angular plate 55. Cam gear 53 drives the eccentric cam 56. pin 51 fixed to a yarn carrying member 59 rides 86 shows the yarn feeding mechanism pivoting 95 which is mounted to the carrier ring 96 by screws-91. The feeding mechanism 86 has a bullet catch 98 to maintain the yarn feeding mechanism 86 in two positions: the knitting positionand non-knitting position. The yarn feeding mechanism has a pair of fingers upon which I are mounted upper' roller 99 and lower roller I00. The yarn IN is fed to the knitting needles through openings I02 and I03 of the yarn feeding mechanism 86. Referring to Fig. 15, a mechanism I04 is mounted on plate 95 for holdin the yarn IOI taut. This mechanism comprises a moveable plate I49, a spring I0'I attached to a lug I08 on plate I49, the opposite end of spring I0! is attached to a regulating screw I05, said screw I05 passes through a lugl50 on plate 96 and is adjusted by nuts I06 on both sides of lug I05, thus regulating the tautness of spring I0I.

Moveable plate I49 has openings I5I for pins A roller within a circular cam grove 59 of the cam 56 causing a reciprocating motion of the yarn carrying member 59. Yarn carrying member 59 rides in a housing 60 rotating bearing wheel 6| and small driving wheel 62 by a rack gear 68. The driving wheel 62 rotates a cutting blade 63. The

which is attached to horizontal plate 38.

A 'gounted to the stationary frame-' work by a cla p 64 to pipe 43 and by plate 65 The yarn carrying member59 terminates in a This gear ratio permits the yarn carrying member 59 to reciprocate between the yarn holders 10, as shown in Fig. 2.

Referring to Figs. 9 to 12, inclusiveflaams II;

attached to any desired section II6, motivate lever I3 which in turn moves plate I4. Hook I5 is attached to plate I4 and is moved reciprocally by plate I4. Hook I5 rotates chain wheel I6 upon which rests a chain 11- comprised of links of different heights; small links 18, medium links I9, and large links 80. The small links I8 change the knitting position parts to non-knitting position. The medium links I9 cause no change in the position of any of the parts]. The large links 80 change the parts from non-knitting to knitting position. The chain 11 operates pin 8I on lever 82 causing lever 82 to be elevated or dropped vertically, depending upon the height of the links of chain 11. Lever 82 moves links 83 and 84. Link 83 moves plate 85 which in turn moves the yarn feeding mechanism 86. Link 84 actuates upper and lower tucking bar'plungers 81 and 88, respectively, which in turn operates" tucking bar 89, and tucking bar release 90, re-

spectively. Tucking bar 89 terminates in a tucking bar cam 89', which moves the needles'into knitting position.' A plunger cam 9| is attached to lower tucking barplunger 88 which operates stitch cam control plunger 92.

Referring to Figs. 13 to 24, inclusive, numeral I52 to maintain plate H9 in its reciprocal movement. Yarn IOI passes underneath hook I09 which is mounted upon mechanism I04 and through openings I02 and I03 and is held by spring IIO which is mounted in yarn holding mechanism III attached to carrier ring 96 by screw II2.

Carrier knife H3 is mounted vertically upon plate 95. Knife II3 helps to completely open the latches of the needles '4 and helps to feed the yarn to the hooks of the needles II 4, The cams of a feed are held upon a block constituting a section of the cam ring and here indicated as II6. Such a section includes in this case, a

stitch cam 93, a rising cam 1, a tucking bar 89, a tucking bar release 90, plunger 92 and stitch control mechanism. The stitch. control mechanism comprises a T shaped pin II8, one

leg of which rests upon tucking bar 89 and the other leg upon the head II9 of plunger 92. Pin II8 rests within housing I20 and acts upon one end of pivot lever III pivoting about screw pivot I22 which is screwed to housing I20. Adjustable screw I23, mounted upon the opposite end of lever I'2I rests upon stitch cam lug I24.

In order to obtain diiferent horizontal stripes of various colors, certain feeds in the knitting machine will feed aparticular colored yarn to the knitting needles to produce a horizontal stripe of that color. The subsequent colored horizontal stripe in the knitted fabric is produced by placing feeds containing the desired colored yarn into knitting position and placing the otheryarn feeds into nonknitting position.

To obtain this result, I will describe the operation of my improved knitting machine. I will first describe the manner of disengaging the knitting feeds and placing such feeds in the nonknittlng position.

Referring to Fig. 10, a cam II actuates lever I3 causing the movement of plate I4 to move hook I5. Referring to Fig. 9, hook I5 moves chain wheel I6 which revolves design chain I'I containing links of three different heights. As illustrated in Fig. 9, pin 8I rests upon small link I9 so that lever 82 drops causing links 83 and 84 to move to their downward positions. Referring to Fig. 12, link 83, shown in downward position, causes plate 85 to descend and pivot about pin 131. The yarn feeds 86 are mounted upon revolving carrier ring 96, J shown in Fig. 14, so

that when plate. 85 is inits downward position, lower rollers'lflll of the yarn feeding mechanisms 86 will strike plate 85 in their revolutions, causing the yarn feeding mechanisms 86 to move about pivot pin 94. This movement causes the yarn IN to be tensioned between hook I09 and the yarn feed opening I02. The yarn IN is moved away from needles I I4 by the lower opening I03 of the yarn feed mechanism 86', shown in Figs. 14, 16, 22 and 25. The tensioning of I yarn IOI is accomplished by causing hook I09 to be held in close proximity to opening I02 by the mechanism I04. The taut yarn leaves the needles at one point of the circumference of the circular cylinder I39; as shown in'Fig. 1, such point being designated at I38 of Fig. 2L

The rotation of the knitting frame, as'shown I er as lower feed mechanism openings I03 move away circumferentially from point I38. As yarn IOI moves away from point I38, the yarn carrymg member 59 advances and catches the taut yarn. IOI'between the fingers 86 and 51. As the yarn carrying member 59 recedes, the taut yarn IN is pulled back by lower fingers 86 so that the i yarn I0! is pulled into the spring IIO of the yarn holding mechanism III, as best shown in Fig. '14, thus holding and locking the yarn IOI between spring H0 and the yarn holder 10. As the yarn carrying member 59 recedes still further, it carries the yarn I.0I across the cutting blade 63, thus cutting the, yarn IOI; one end of the'yarn being held by the yarn holding mechanism III, as shown at point I44, Fig. 2, until it is again required for knitting and the other end remains hanging loosely from the knitted fabric, as shown at point I38, Fig. 2.

As link 83 is moved downward by lever 82, link 84 is also moved downward causing lower tucking bar plunger 88 to move inward, as shown in Fig. 12. At the same time that lower. roller I00 of the yarn feeding mechanism 85 strikes plate 85 in its lower position, the tucking bar release 90 strikes roller 88 (Fig.- 20) .mounted upon lower tucking bar plunger 88. This action causes tucking ,bar 89to move about pivot pin I'40 as shown in Figs. 14 and 15, so that tucking bar cam 89' at the other end of tucking bar 89- (Fig. 15) moves downward, allowing the needles II4 to remain in tuck or non-knitting position, as shown in Fig. 24.

Referring to Figs. 13 and 15, as tucking bar cam 89' moves downward, pin II8 descends re-.

leasing lever I2I, which pivots about screw pivot I22. This frees the compressed spring I, causing an upward movement of stitch cam lug I24.

As stitch cam lug I24 moves upward, it also moves stitch cam 93 upward, since it is attached thereto (as shown in Figs. 13 and 24).

The rising action of stitch cam 93 of the nonknitting section II6 permits the needles II4 to be drawn down to a position not as low as the knitting position, thus avoiding undue tension of the wales on the needles II4 while passing the non-knitting feeds. This positioning of cam 93 prevents distortion of the wales of the knitted fabric.

being in a higher position. Suchtight wales cause damage to the knitted fabric over this 1 H6, is moved forward by cam 9| attached to lower tucking bar plunger 88 (Fig.20). One leg of theT shaped pin II8 lies in the path of the head II9 of plunger 92 (Fig. 18). Cam 9I pushes plunger 92 inward, so that head II9 prevents pin II8 from dropping when the tucking bar cam 89 is being lowered. Pin 'I I8 holds ,pivot lever I2I in the knitting position, so that the stitch cam 93 is held in'the said position over the changing area. When the plunger 92 passes plunger cam 9|, compression plunger spring I43 causes the head I I 9 to return to its former position allowing pin II8 to drop so that the stitch cam 93 is permitted to rise to the non-knitting position.

I will now describe the manner of engaging the non-knitting feeds and placing such feeds in the knitting position.

Referring to Fig. 9, when large link 80 of chain 11 is moved into position by hook 15 under pin 8|, it raises pin 8| which in turn lifts lever 82, causing links 83 and 84 to move upwardly. Referring to Fig. 11, when link 83 is moved to an upward position, it causes plate 85 to rise so that upper rollers 99 of the yarn feeding mechanism 86 are caused to pivot about pivot screw 94 upon passing plate 85 in their revolutions around the cylinder. Such action places the 'yarn feeding means 86 into the knitting position, as shown in Referring'to Fig. 24, the distance between tuck-' ing bar cam 89 and knitting point I42 is known as the changing area, i. e. from knitting to nonknitting. As tucking bar cam 89' is' moved downward, cam 93 automatically moves upward to the dotted position shown in Fig. 24, causing the knitting needles over thischanging area to knit very tight wales caused by thev stitch cam 93' Fig. 23, and in this position the ten'sioning of the yarn IN is automatically released when the yarn feed opening I02 is moved away from hook I09.

As link 83 is moved upward by lever 82, link 84 is also moved upward, causing upper tucking bar plunger 8'I'to move outward, as shown in Fig. 11. At the same time that upper roller 99 of the yarn feeding mechanism 85'strikes plate 85 in its upper position, upper tucking bar plunger 81 strikes tucking bar 89, moving it downward about pivot point I40. Spring I45, acting on tucking bar release causes the release 90 to lock tucking bar 89, as shown in Fig. 31. The movement of the tucking bar 89' causes the bar cam 89' at the other end of the tucking bar 89 (Fig. 15) to move upward, thus placing the needles II4 into knitting position, as shown in Fig. 24.

Referring to Fig. 31, as tucking bar cam 89' (Fig. 15) moves upward, pin H8 is' moved upward and raises lever I2I which pivots about screw pivot I22, causing the adjustable stitch screw I23 to descend and depress the stitch cam lug I24, which in turn lowers the stitch cam 93 to the desired knitting level.

As the yarn feeding mechanism 85 is moved into knitting position, as shown in Fig. 23, the yarn opening I03 brings the yarn across the path of the cylinder .needles I I4, raised by tucking bar cam 89', so that the hooks of 'the needles II4 cross and take the yarn IOI, as shown in dotted lines in Fig. 25, and knit the yarn I 0| into the fabric. As the needles II4 draw the yarn IM to be knitted into the fabric, the yarn IN is auto-- have a twenty-four feed machine, the first twelve feeds of said machine containing yarns of the first color and the following twelve feeds containing'yarns of the second color. Assuming, also, that all the feeds are in a non-knitting position at the commencement of operation.

At the beginning of each section of the two colors, a cam 1| is placed in a section 6, thus having two cams 1| in my example. When the first cam 1I actuates the chain mechanism, a

large chain link, of a design chain 11 pre determinedly arranged, causes the feeds following said cam 1| to move into knitting position as aforedescribed, until the second cam II again actuates the chain mechanism to a medium chain link 19, which permits the feeds following the second cam to remain as originally, that is, in

main unchanged as in the first revolution. This will make forty-eight knitted courses (four times twelve knitted courses) in addition to the twelve knitted courses of the first revolution, so that we have the desired sixty knitted courses of the first color. As the gear base I46 makes its next, or

sixth revolution, the first cam II moves the chain.-

mechanism to a low link '18, causing the knitting feeds following the said cam to move to a non-"knitting position, as previously described; the second cam 1| moves the chain mechanism to a large link 80, causing the non-knitting feeds following this cam to move to a hitting position. This revolution of thegear base I146 causes the disengagement of the feeds containing the first color and the knitting of twelve coursesof the second color.

For the following four revolutions, the cams U will actuate the chain mechanism each time they pass lever 13. Since the eight chain links 19 following these movements are of medium height, all the feeds will thus remain unchanged, as in the sixth revolution. This will make it" forty-eight knitted courses, in addition to the twelve knitted courses of the sixth revolution. so that we have the desired sixty knitted courses of the second color. These colored stripes are knitted repetitiously in the same. manner.

It can thus be readily seen that any tion of horizontal stripes are possible by placing difierent colors in different feeds in the machine and placing cams 1I before each such section of feeds containing a different color.

In order to increase production and obtain a greater combination of different colored stripes with the same number of feeds, as hereinbefore described, a new yarn feeding mechanism I26,

as shown in Fig. 2'1, is used in place of the yarn feeding mechanism 86. This yarn feeding mech alternately to the knitting needles Ill in the same feed section. This doubles the number of knitting yarns upon the machine so that a greater mnnber of combinations of yarns and colors canbe obtained and permits a greater number of 'feeds'to be operated at the same time because of the greater number of knitting yarns, -thus increasing production. .The yarn feeding mechanism I26 can be used to greater advantage in combination with my jack wheel I33as shown and described in my Patent Number 2,000,837, or with other types of jack wheels so as to obtaina combination of stripes and design patterns.

Yarn feeding mechanism I26 is controlled in a similar manner as yarn feeding mechanism 06, previously described. The positive positioning of said feeding mechanism. I26 is accomplished by detent and spring control I36. When plate 85 is in the highest position, it strikes upper roller I26, causing the yarn holding finger of feeding mechanism I26 to move downward. Ratchet extension I3I on finger I26 revolves gear I32 which in turn moves ratchet extension I30 on finger I21, causing finger I21- to move outward about pivot point 94. This operation places yarn "II to the knitting position and yarn IN to the nonknitting position. The tautening, holding and cutting of the non-knitting yarn is accomplished in the same manner as hereinbefore described. When plate 85 strikes lower roller I29, the above action is reversed. It is also possible to actuate roller I29 so that both fingers I26 and m are in.

a non-knitting position. This is accomplished by stopping the yarn feeding mechanism I26 at a position where fingers I26 and I21 are ccngruous. when both fingers I26 and I21 are congruous and not knitting, both non-knitting yarns are 1. In a multiple feed circular knitting machine,
