The numeral I designates the knitting machine generally, 2 the circular base on which is mounted in the usual manner a needle cylinder 3, sinker head 4 and latch ring 5, the latter being retained in lowered, operative position by means of a latch 6 engaging overa pin 1 carried by the mouthpiece 8 which is an extension of the latch ring. The mouthpiece 8 carries the usual yarn levers 9 adapted to feed threads i0 including body and plating threads, heel and toe threads, and such striping threads as may be interchangeably knit in from time to time.

Carried by an extension of the circular base or bobbin stand 2' is a drum l| mounted to turn upon a vertical axis and racked from course to course or as desired by a pawl means 12 suitably controlled from the "104" gear and in engagement with ratchet teeth l2. The drum i has mounted on its surface or periphery cams l3, and H. The cams i3 are adapted to engage arms of levers i5 pivoted at l8 upon a vertically disposed pin I! mounted in lugs l8 forming part of a bracket 9 which is fastened to the yarn lever box 20 while the other arms of the levers l5 engage other levers 2| pivoted intermediate their ends at 22. Engagement of one arm of a lever I5 by a cam l3 rocks the said lever I5 upon its pivot, whereupon the other arm of the lever rocks a corresponding lever 2| upon its pivot against the tension of a retractile spring 23, one end of which is connected to one arm of the lever 2| while the other end of the said spring is connected to a vertically disposed post 24 attached to the circular base as at 25. The rocking of a lever 2| causes a pin 26 depending from the other arm thereof to engage and move a corresponding slide 21 which carries a jack raising cam 28 at its inner end adjacent the cylinder. Jacks mounted within the slots of the needle cylinder and beneath the needles have butts 28' thereon located at different elevations. At one such elevation butts are in position to be engaged by the lowermost cam 28 while the other butts are correspondingly positioned to be engaged by the other cams 28. The engagement of the jack butts by the cams 28 causes the said jacks to be raised, which jacks in turn raise their needles to an elevated position all as disclosed in Fig. 41 of the Lawson Patent 1,702,608 for the purpose of taking and knitting in the lap or wrap stripe threads or yarns.

Mechanism for carrying out the method and knitting the product with which this invention is especially concerned is specifically disclosed in Figs. 2-13 inclusive, wherein 29 and 6| designate supplemental or wrap stripe thread guide carriers or discs carrying depending, porcelain or other eyes 30, 62 and 10 by means of which supplemental threads or yams 3| are fed to needles selectively raised as hereinbefore described.

Whereas in the Lawson Patent 1,702,608 the carrier 1 corresponding to carrier 23 is shown as mounted to rotate in time, preferably, one and one with the needle cylinder, so that the same yarn will alwaysbe fed to or wrapped around the same raised needles, the mechanism herein disclosed changes the yarn or thread fed to or wrapped around the certain selected needles so that in the clocking or other areas or stripes the threads 3| are interchangeably knit in by the selected needles whereby in a lengthwise extending stripe threads or yarns 3| of different colors may be knit in.

In the form specifically disclosed in Figs. 4, 5, and 6 the desired thread or yarn change is the result of a circumferential shifting of the disc or guide carrier 23, so that a certain guide eye 33 feeds its thread to or wraps it around certain selected needles for a desired number of courses and thereafter a second guide eye 30, preferably the eye next adjacent to the first mentioned eye, feeds its thread to or wraps it around the same group of needles theretofore having knit in the first mentioned clocking or striping thread. In

plate over the said body thread or threads for a desired number of courses. Thus the first and second mentioned clocking threads 3| each replace the other at intervals.

The means specifically disclosed in Figs. 4, 5, and 6 to change the color of the clocks includes an upper disc 32 and a lower disc 33 which two discs 32 and 33 clamp between them the heads of the porcelain eyes and thereby rigidly maintain them in proper position. Rising vertically from and rigidly connected to the lower disc 33 is 'a shaft 34 and surrounding the same and fastened thereto as by a screw 35 is a hub 35 which maintains the upper disc 32 in clamping engagement with the heads of the porcelain eyes 33. Shaft 34 is received within a hole 31 provided in a sleeve or shaft 33 which is in alignment with the hub 33 but is prevented from tuming therewith. The shaft 38 provides a suitable bearing for the shaft 34 to which turning movements are imparted by means of a pin in the form of a screw 33 fast to the said shaft 34, the outer end of which pin 33 projects radially through a horizontally disposed slot 40 provided in the shaft 38 and also through a diagonally disposed or inclined slot 4| provided in a hub 42 carried by a grooved disc or yoke 43. The disc 43 carries supplemental porcelain eyes 44 through which the threads 3| pass on their way to the first mentioned eyes 30. The guide carrier 23, as hereinbefore stated. is driven to rotate one and one with the needle cylinder and by mechanism similar to or identical with that disclosed in the patent to Lawson 1,702,608, but the means for so rotating'the guide carrier 23 in time with the needle cylinder is not a necessary part of the present invention and is not disclosed specifically herein. As the yoke or disc 43 is raised or lowered'to and from the positions of Figs. 4 and 5 the walls of the inclined slot 4| engage the head of the screw or pin 33 and cam the said pin 33 to or from the positions of- Figs. 4 and 5 thus causing the stub shaft 34 to which th pin or screw 33 is connected to rotate or move through:

an are determined by the length-and inclination of the slot 4|. The hub 42 and yoke 43 are held from turning on the sleeve or shaft 33 by means of a keyway 45 provided in shaft 33 and a pin or screw 43 passing through the yoke 43 and into the said keyway 45. As shown in Fig. 6 eight porcelain eyes 33 are circumferentially arranged around the carrier 23 and equi-distantly spaced. Accordingly the slot 4| is adapted to move the carrier disc 23 through an arc of approximately 45 degrees thereby causing the next adjacent eye 30 to asume the exact position, with respect to certain needles, as was occupied by the eye 30 which previously fed a wrap or supplemental thread to the said certain needles. However, the circumferential movement of the guide carrier 23 due to the inclined slot 4| and pin 33 may be more or-less depending upon the number, arrangement and disposition of the eyes 30 in the carrier 23.

The means for periodically raising and lowering the yoke or disc 43 is specifically disclosed in Figs. 2 and 3, wherein a lever 41 is provided with arms 41' the ends of which carry pins 48 that project into the groove of the disc or yoke 43. The lever 41 is normally maintained in lowered position by means of a spring 43 one end of which is attached to a pin 50 carried by the said lever 41 and the other end of which is attached to a convenient part of the machine frame. The said lever 41 is pivoted at 5| to an upright bracket 52 carried by the circular base to which bracket is also pivoted a lever 53 having at one end thereof a pin 54 engaged within a groove of a disc 55 fast to the shaft 33 so that upon elevation of the disc 55 the guide carrier 23 is raised to a position above the needles. The lever 53 controls the upward movement'of the disc 55 and guide carrier 23 as and when dictated by pattern mechanism not shown and not of itself a part of the present invention. The disc 55 is raised prior to levelling needles for transfer and heel and toe knitting. Pivoted coaxially with the lever 41 upon the pivot 5| is a lever 56 which is provided with a laterally extending lug 51, with which the underside of the lever 41 is normally held in engagement by means of spring 43. The lever 53 depends freely from its pivot 5| and at its lower extremity is normally in contact with one arm of a second and horizontally disposed lever 58 pivoted at 53, intermediate its ends, to a post upstanding from the circular base,

the other arm of lever 58 having a lug 50 in engagement with the surface of the drum II or cams |4 thereon. When in engagement with the surface of the drum II, as shown in Fig. 3, the lever 53 maintains a true vertical position as shown in Fig. 2, the spring 43 at such time maintaining the lever 41, in lowered position and consequently with the parts in the position shown in Figs. 2 and 4. When, due to the racking movements imparted to the drum H by the pawl and ratchet l2, a cam 4 engages the lug 60 of the lever 58 and rocks the latter, the otherarm of the said lever swings or rocks the lever 56 to such a position as to cause the lug 51 thereon to raise or elevate the lever 41, which lever in turn raises the disc 43 from the position shown in Fig. 4 to that of Fig. 5 with the result that'the clocking or other thread or yarn 3| previously fed to or wrapped around the certain selected needles for the desired number of courses is angularly displaced and to such a position with respect. to the needles as to wrap around another group of selected needles, while a second thread 8! adjacent to the first, at the same time wraps around the group of needles first mentioned.

In Figs. 7-13 inclusive is disclosed a modification of the means for changing the color of the clocking or other stripes whichrnodifled means includes a guide carrier 8| corresponding in some respects to guide carrier 29 of Figs. 4 and 5. Porcelain or other thread guiding eyes 82 are held between two plates or discs 63and 64 clamped against the opposite sides of the heads of the eyes by means of a knurled screw 85 the shank-of which threadedly engages a stub shaft or rod 68 received within a hole 81 provided in a sleeve or shaft 68. The shaft 88 turns one and one with the needle cylinder. and carries around with it the stub shaft 66 and discs 63 and E4. The stub shaft is made fast to the shaft 88 as by means of a set screw 89, and the porcelain eyes 82 thus, from course to course, maintain the same positions, with respect to their needles in the needle cylinder so as to wrap clocking or other threads around the same groups of selected needles. In other words, a porcelain eye is always in position to feed thread to or wrap thread around the same group of needles, whereas in Figs. 4 and the corresponding eyes 38 are shifted circumferentially through an angle of approximately 45 degrees to change the thread or yarn wrapped around selected groups of needles.

In addition to the relatively fixed porcelain eye 62 there are provided additional thereto other and interchangeable, steel eyes 18 two sets of two each being disclosed in the drawings although any desired number of pairs obviously may be utilized if desired. The steel eyes 18 depend from and are carried by levers or guides H slotted as at 12 at their inner ends and within which slots, pins or screws 13 are received. The screws I3 control the in and out interchangeable movements of each pair of steel eyes and threadedly engage and pass through corresponding holes provided in a plate or disc 14 which is recessed at 15 to receive and house an idle eye I8 of each pair while the other such eye is in the active feeding position all as shown in Fig. 10. The plate 84 is shown as provided with V-shaped slots 16 within which slots thickened portions 11 of the levers 1| are received and guided in their movements to and from feeding positions. The thickened portions 11 provide shoulders 18 which abut against the ends of the slots 16 when the levers 1| are in retracted position. and the inner ends of the said levers are reduced beyond the shoulders as at I9 where the said levers slide upon the upper surface of the plate 64. i The plate or disc 14 is carried by a hub 88 journaled within a bearing 8| provided by the relatively fixed sleeve or shaft 88. The hub 88 terminates a short distance above the disc 14 and there engages shoulders 82 provided by the sleeve or shaft 88. Projecting radially outward from the hub 88 is a pin or screw 83 extending through a horizontally disposed slot 84 in the shaft 88 and through a diagonally disposed or inclined slot 85 provided in a hub or sleeve 86 which surrounds the shaft 68 and is fixed thereto against turning independently thereof as by means of a set screw 81 engaging a keyway 88 in the shaft 88. The screw is held in place by an additional. locking screw 88.

In the form of the invention disclosed in Figs. 7-13 inclusive, as well as in the first described form, pins 48 carried by the arms 41' of the lever 41 engage the groove of the yoke or disc 88 is knit in in a succeeding course.

as determined by the cams 14 upon the drum I l and connections therefrom, and thereby raise and lower the said disc 88 to interchange the clocking threads 3t wrapped around selected needles by means of the eyes I8. Fig. 7 shows the yoke or disc relatively raised and at such time one eye 18 of each set is in feeding position while the other eye is restracted and housed within a recess 15 provided in the plate 14. As the disc 98 and hub 86 move down from the position of Fig. 7 to that of Fig. 8 the diagonal slot engages the pin 83 and cams the same to the right from the position shown in Fig. '7. The pin 83 carries with it the sleeve 88 and the disc or plate I4, which plate by means of the pins I3 engaging in the slots 12 causes one lever ll of each pair to move from a projected position to a retracted position and simultaneouslyv therewith moves the retracted lever H to a projected position. The steel eye 18 carried by the lever second mentioned is thus moved to a position to feed to or wrap its thread around the certain selected needles theretofore receiving thread through the companion eye I8.

The clocking mechanisms disclosed in Figs. 4-6 and Figs. 7-13 respectively, may each be replaced by the other by loosening a set screw 46 or 81, removing the clocking mechanism and substituting the other therefor. Furthermore the two clocking mechanisms may be used in conjunction the one with the other. 7

Figs. 6a and 13a illustrate how the wrap threads are carried from positions within the needle circle to positions to the outside thereof and finally back to positions within the needle circle. The needles N which are mounted within tricks or grooves in the needle cylinder 3are arranged in a circle having a greater diameter than either guide carrier and as a consequence thereof, and the fact that the needle cylinder and guide carriers are rotated in timed relation with one another, the needles have a greater peripheral speed than the threads which pass through the eyelets in the guide carriers, the result being that the needles gain with respect to the wrap threads.

In Fig. 14 a stocking is shown having knit therein by the methods herein described a clocking area or stripe A flanked on each side by stripes B and C which stripes'extend lengthwise of the stocking.

In Fig. 15 a few wales and courses are shown with the body thread 9| and the plating thread 92 knit in throughout and a third, wrap stripe thread 3| knit in at certain wales as at 93 and floated therebetween at 94. The floats 94 are the result of the failure of jacks to raise their needles to a level to knit in the wrapping thread 3|, which thread consequently floats back of the threads SI and 82 taken and knit in by all of the needles at the mouthpiece. The floats 94 constitute knitting floats or floats resulting from needle selection. In addition to the knitting floats 94, wrapping floats 95 extend from the last Wale where a thread 3| is knit in in one course to the first Wale where the card thread Each thread 3| is adapted to be fed to and wrapped around ten to fourteen adjacent needles. the number of such needles actually knitting in a wrapping thread 3| depending upon the number of needles selected by the jacks and cams 28 as hereinbefore described. As disclosed in Fig. 15 a thread 3| spans seven wales, the first, third, fifth, and seventh wales having knit therein the said thread 3| for four courses preceded by a few courses with the said thread II knit in at the second and sixth wales only. 4

The wrapping floats 95, Fig. 16, are shown at 90, 91, and 90. The threads II are knit in on the face of the fabric as stripe D, E, and F. For the first few courses indicated, Fig. .16, a separate thread II is fed to and wrapped around three adjacent series or groups of needles by means of the eyes 30, Figs. 4, 5, and 6, which needles are selected as hereinbefore described. During the knitting of the said first few courses the yoke 43 is in the position shown in 1'18. 4. To change the colors of the stripes D, E, and I" yoke 43 is shifted from the position of Fig. 4 to that of Fig. 5 thereby moving the eyes 90 circumferentialiy or laterally through an arc of approximately 45. degrees so that the threads 3| that theretofore were knit in as stripes D, E, and F float laterally as indicated by the numerals 99, I00, and IOI respectively. The lateral displacement of the threads SI permits a change in the color of all the stripes D, E, and F, so that a continuation of the stripe E has knit therein the thread theretofore knit in as stripe D; while the continuationv of the stripe D has knit therein the thread ll theretofore knit in as stripe F; while the said stripe F has knit therein. a thread 3| which either floated as indicated at I 02 from a stripe adjacent to the stripe F (not shown) or was theretofore idle because it was not knitted by any of the needles; while the thread theretofore knit in as stripe E floats as at I00 to an idle position or to be knit in as a stripe (not shown) and adjacent to the stripe E. After knitting in the desired number of courses with the threads 9| in the second named position, they may be either returned to the first position or again shifted laterally in the same direction. If shifted back to their original positions, floats I03, I04, I05, and I00 return all four threads II to their original stripes. The wrapping threads 3|, in all cases, float from the last wale where knit in, in one course, to the first wale where knit in, in a following course.

Operation of the clocking mechanism, Figs. '7-13 inclusive, changes the color of a given stripe such as G, Fig. 17, and avoids the objectionable floats 99-400, Fig. 16 which floats 99I00 are replaced by wrapping floats I01, I00. connected by floats I09, III, that cross the courses and floats I01, and I00. The floats I09 and III extend lengthwise of the stocking or other fabric and from the last mile where knit in in one course of knitting to the first wale where knit in in a succeeding or following course. The float I09 extends in a substantially straight line from wale to wale whereas the float H0 is deflected from a straight line by the float I09 so that one part of the float IIO extends from the last wale where knit in to the float I09 and the other part or extension of the float I I0 passes from the float I09 to the other side or edge of the stripe G where it is again knit in. Lengthwise extending stripes H, I are, preferably though not necessarily, knit in adjacent to the clocking area G by threads 3| which are fed to and wrapped around selected needles by the porcelain eyes 02.

The stripes D, E, F, G, H, and I may span the same number of wales from course to course as indicated in Fig. 16 or they-may span an increasing or decreasing number of wales as indicated in Fig. 1'7.

While the body and plating threads 9|, 92 are shown'in Fig. 15 as knit in throughout, either one or both 'may be floated where the wrap stripe thread or threads II are knit in or at any other desired place in the fabric for ornamental or other purposes.

The wrapping floats and floats which extend across the wales may be severed if desired. While this invention is herein disclosed as applied to a machine of the circular, independent needle type, the invention in all respects is not limited thereto. but is also adapted to other types of knitting machines than those having independent needles arranged in a circle and furthermore while it is herein disclosed as applied to hosiery machines it is equally adapted to be used in connection with so-called body machines if desired.
