The stocking represented by the reference character 1, Fig. 1, which is produced by the methods and mechanisms hereinafter to be described, is, preferably but not necessarily, knitted from the toe to the top thereof. During the knitting the usual loopers rounds (not shown) are knitted by. all of one set of needles, usually the cylinder needles, alone knitting. Thereafter one-half more or less of the cylinder needles knit a toe 2 in a usual manner after which a few courses constitut ing the so-called ring toe 3 are knitted by all of the cylinder needles following the knitting of which a ribbed instep 4, preferably though not necessarily of one and One rib, is knitted by one-half more or less of the cylinder needles in conjunction with interspersed dial needles, and at the same time the sole 5 or lower portion of the foot is also knitted and by the remaining cylinder needles knitting alone, i. e., not in conjunction with dial plain heel 6 which is knitted inany desired manner and preferably by one-half, more or less, of the cylinder needles. At the completion of the knittin of the heel 6 the instep needles are restored to action and during the knitting of a desired number of courses the instep dial and cylinder needles knit a con- 1 tinuation of the ribbed instep above the heel as indicated at 7 during the knitting of which continuation of the instep the needles, which ,theretofore knitted the double or reinforced sole, knit the same threads they were knitting during the formation of the double sole 5, whereby a high splice or heel reinforcement 8 is produced. After the desired number of partially reinforced courses have been knitted, the dial needles, companion to the high splice cylinder needles, are advanced to knitting position and they in con unction with the high splice cylinder needles and instep dial and cylinder needles knit an all round ribbed leg 9 of one and one or other desired proportion of rib and plain wales. At 10 is indicated the top of the stocking which may be of finer rib 1n' the event the leg is knitted of coarser rib such as four and one, and/0r may be knitted ,with a finer or lighter thread and with shorter or tighter stitches to provide a garter top. Tuck welts 11 may be provided if desired.

Preferably the heel 6 as shown, Fig. '1, does not extend to the first rib wale of the instep but stops short thereof to provide intervening plain wales as at 12 between the heel suture and the first rib wale.

In Figure 2 is shown a section of the stocking, Fig. 1, one-half more or' less of the wales of which are of one and one rib while the remaining wales are plain wales having knitted therein an additional and/or rein forcing thread. By the methods and-mechanisms hereinafter to be described the min forcing thread is knitted in by the plain sole needles only and floated between the last and first knitted in reinforced wales of successive courses which floats are severed adjacent to one reinforced wale, as hereinafter to be described, thereby providing long floats 13 and short floats 14 which floats especially the long floats 13 may be, and preferably are, sub sequently removed, although the short floats 14 may be temporarily held, but not knitted in, between a few adjacent plain and rib wales as shown by the dotted line position 14 of the floats 14, the confined short floats shown being readily pulled out from between the adjacent rib and plain wales by a suitable implement whereu on they assume a position within the nee le circle such as shown in full lines, Fig. 2.

The knitting machine 15 (Fig. 8) herein disclosed, by way of example as of the rotary needle type, is provided with the usual needle cylinder 16 and needle dial 17 which are the underside of which are

cams

19, 20 for controlling the dial needles 21 in their movements to and from knitting position and a cam 22 for advancing the dial needles 21 to cast ofl their stitches. Likewise cams (not shown) control the movements of the cylinder needles 23 to and from thread taking and knitting positions. The needle cylinder 16 is driven in any suitable manner as by means of a ring gear (not shown) which is mounted in and supported by the circular base 24 (Fig. 8) and is driven in any suitable manner as by means of the usual gearing (not shown).

For carrying out the purpose of the present invention mechanism is provided, one form of which is disclosed specifically in Figs. 2-14 inclusive wherein a cam drum or disc 25 is shown as fixed to a cam shaft 26 upon which are mounted cams (not shown) for controlling and timing the various operations of the knitting machine. Upon the periphery of the drum or disc 25 are fixed came 27 and 28 between which are

spaces

29 and 30 on the surface of the drum. The.

drum 25 is advanced in the direction of the arrow, Fig. 8, from time to time as dictated by In s on the usual pattern chain (not The stockings or half hose which are knitted upon the present machine are, preferably but not necessarily, knitted from toe to top, and during the knitting of the leg of each stocking as well as the loopers rounds, toe and ring toe, the toe 31 of a .lever 32 rests upon the surface of the cam 27 and just prior to the first course of the double sole said toe 31 of lever 32 drops off the cam 27 and onto the surface of the drum at 29 as hereinafter to be'more fully described. Th toe 31 rests upon the surface of thedrum' throughout the knitting of the double sole, but, preferably, immediately prior to the knitting of the first course of the heel the cam 28 engages the toe 31 and rocks the lever 32 and the parts remain in the same relative positions until the knitting of the heel is completed when the toe 31 of the lever 32 drops off the cam 28 onto the greferably, rotates one complete turn or 360 egrees during the knitting of a single, complete stocking'or half hose.

The toe 31 isadjustably or otherwise fastened to one arm of the lever 32 by set screws 33 and the lever is pivoted intermediate its ends as at 34 to the machine frame. To the other arm of the lever 32 is pivotally connected an'adjustable link 35 which extends vertically througlra hole provided in the c1r-.

cular base 24 and to the projecting end of the said link 35 is pivotally connected at 36 a link 37. The other end of the last named link (Fig. 11) is rigidly fastened to a shaft 38 which-passes axially through an enlargement or hub 39 carried by and forming part of the link 37.to which the said shaft is rigidly fastened by means of a screw or nut 40 whereby rocking movements periodically imparted to the lever 32 as hereinbefore described are communicated to the said shaft 38 through the instrumentality of the

links

35 and 37. The shaft 38 is journaled for turning movements in

upstanding ears

41, 42, 43 carried by or forming part of a bracket 44 rigidly attached to the bobbin support which is a continuation of the circular base 24. To the other end of the shaft 38 is aflixed a lever arm 45 as by means of a set screw 46 which passes through and is in threaded engagement'with a hub or enlargement 47, which constitutes one end of lever arm 45, and in contact with shaft 38, whereby to rigidly connect the arm 45 to the shaft 38. The lever arm 45 at its free end engages under a pin 48 which extends laterally from and is connected intermediate the ends of a lever 49 which lever is provided with a cam engaging toe 49 and is pivoted adjacent one end thereof upon a shaft 50. The shaft 50 projects through and is rigidly supported by the upstanding-ears 42, 43 between which.

the lever 49 is mounted. A portion of the shaft 50 projects laterally from the upstanding ear 42 and encircling the same is a coil spring 51 one end of which is rigidly connected to a nut 52 mounted upon the shaft 50 and prevented from turning thereon as by means of a locking screw 53 and-a washer 54. The coil spring 51 at its other end extends substantially parallel with the lever 49 as at 55 and the end of such spring is turned at a right angle as at 56 thereby to engage with the upper face or edge of the lever 49. The end of the lever 49 opposite its pivot is offset as at 57 which offset endengages'in the bifurcation provided 1 one arm 58 (Fig. 10) of a bell crank lever 59 which is pivotally supported upon a pin or screw 60 carried by an ear or lug 61 upstanding from and forming part of the bracket 44.

A cam 62 (Figs. 9, ll, 13) is mounted upon and forms part of a sleeve or cam drum 63 which is in turn made fast to a shaft 64, the cam 62, during the knitting of the double sole and high splice, engaging toe 49' and rocking lever 49 each course as the shaft 64 is rotated once each course, and in a man ner hereinafter to be described, throughout all of the courses of the double sole and high splice. The other arm of lever 59 (Fig. 10) is pivotally connected as at 65 to a longitudinally extending link 66 which is composed of two rods adj ustably connected by means of pin and slot connections 67. To the other end of the link 66 is connected .(Figs. 9, 14 and 15) another lever 68. The pivotal connections between the link 66 and the lever 68 consist of a spring 69' fastened to the link 66 as by means of a screw 70 the curved outer arms of which spring 69 engage over the head of a pin or screw 71 the shank of which screw while it is in threaded engagement with the lever 68 as. at 72 is provided with a smooth shank or collar port-ion 73 intermediate the ends thereof. The end of the link 66 is provided with a hole or recess which snugly fits the smooth shank portion 73 of'the pin or screw 71. The described connection between the link 66 and lever 68 provides means for readily detaching the said link from the said lever.

Referring to Figs. 3 and 5, the other end of the lever 68 is shown as connected, integrally or otherwise, to a depending sleeve.

77. The purpose of the collar is to maintain the lever 68 and sleeve 74 in position against the upper face of, the dial cap 18.

Intermediate the ends of the sleeve 74 is integrally or otherwise connected a second arm 78 of the lever 68. Through an elongated slot 79 of lever arm 78 passes a screw 80 the end of which screw is in threaded engagement wlth a plate 81 which constitutes one of the yarn severing members of the auxiliary high splice and double sole cutter.

A coil spring 82 at one end engages .the under face or arm 78 and at its other end engages the upper face of plate 81.

By means of the connections hereinbefore described movements imparted to the lever 68 rock the sleeve 74 and thereby move the plate 81 to and from the open or yarn receiving position shown in Fig. 3 to a position inward thereof where the yarn is severed between the under face of a finger 83 of the plate 81 and the upper face of a plate 84 the peripheral edge of which constitutes a cutting edge or surface companion to or cooperating with the adjacent edge 85 pro vided by the finger 83. A pin 86 retains the plate 84 in osition within a recess or cut-out 87 provided in the upper face or ial cap. As shown the finger 83 is separated somewhat from the body of the plate 81 to provide a V-shaped notch within which notch the high splice and double sole floats are drawn by the continued rotation of the needle cylinder in the direction of the arrow, Fi 3.

In order to feed the reinforcing thread 88 to the needles so that the latter will knit the said reinforcing thread in addition to the main or body thread 89 the high splice and double sole yarn lever 90 is automatically controlled so as to be permitted to move to feeding position at the beginning of the knitting of the doublesole and thereafter of the high splice. The means for so controlling the movements of the lever 90 includes cams 91, 92 (Fig. 8) which are carried by the'usual cam drum 93 rigidly mounted upon the cam shaft 26. Intermittent rotation of the shaft 26 and cams mounted thereon causes the cam 91 to rock a lever 94 which is pivoted intermediate its ends as at 95 to the frame of the machine. One arm of the lever 94 is connected to the wire link 96, which latter is in turn connected to a link 97 and thereby to a lever 98 one arm of which engages under the high splice and double sole lever 90 for the purpose of raising the same out of feeding relation with respect to the needles. At the conclusion of the knitting of the double sole the lever 94 is, due to the rotation of the drum in the directionof the arrow, Fig. 8, engaged by cam 91 and elevated above the surface 99 of the drum. The lever 94 remains on cam 91 until the knitting of the heel is completed and the knitting of the high splice is begun, whereupon the shaft 26 and cams carried thereby are rotated which causes the lever 94 to drop onto the surface of the drum at 100 to permit the high splice and double sole lever 90 to drop to feeding position where it remains throughout the knitting of the high splice. At the completion of the knitting of the high splice, cam-92 again rocks lever 94 whereupon lever 90 is raised out of feeding relation with respect to the needles where it remains until the lmitting of a double sole for the next stocking or half hose is begun when the drum 25 is advanced and lever 94 permitted to drop onto the surface of the drum at 99 where it remains throughout the knitting of the double sole.

In order to have the high splice and double sole needles alone take and knit in the reinforcing thread 88 in addition to the main or body thread 89, during the knitting of the stocking or half hose shown in Fig. 1, the high splice and double sole yarn lever 90 is so controlled as to be dropped to feeding position and raised from such osition once each course of the knitting of t e double sole and high splice. In order to control the high splice and double sole lever 90 in its move- .ments the wire or link 97 (Fig. 8) is connected to and, when movements are imparted to p by means of a spring (not shown). In order automatically to control the movements of the double sole and high splice lever 90 the link 97 is adjustably connected at its lower end as at 100 to a lever 101 which is pivoted intermediate its ends (Figs. 8, 9, 11, 12) at 102 to the lug 61. The other arm of said lever 101 is provided at its'end with a depending toe 103 normally maintained in engagement with or adjacent to the peripheral surfaces of a cam drum or sleeve 104 or of a cam 105 carried thereby by means of the aforesaid spring which normally maintains the lever 90 in thread feeding position. 1

As aforesaid during the knitting of each course of-the double sole and high splice, the

levers

45 and 90 are automatically actuated and in time the one with the other so that, first, the lever 90 is moved to feeding position whereupon the double sole splice needles take and lmit the said thread in conjunction with the body thread and, second, as the last cylinder needle, which knitted the reinforcing thread during the knitting of the preceding half course, reaches the position shown in Fig. 3, the auxiliary cutting mechanism is automatically operated.

In order automatically to control the movements of the lever 90 and the auxiliary cutting mechanism, the hereinbefore mentioned cams 105 and 62 are rotated by the cam shaft 64 and by such rotations actuate their

respective levers

101, 49 and, through the connections hereinbefore described, said levers in turn actuate thethread lever 90 and the auxiliary cutting mechanism. In order to rotate the shaft 64 and cams mounted thereon a gear 106, Fig. 8 known as the 104 gear, meshes with and drives a gear or pinion 107. The 104 gear is driven to make one com plete revolution every four courses'of knitting and as its name implieshas one hundred and four teeth whereas the gear or pinion 107 has twenty-six teeth only'and as a consequence thereof makes one complete revolution during each revolution of the needle cylinder or each course of knitting. The gear 107 is fast to the stub shaft 64 to which is also rigidly secured the sleeve or drum 104. Therefore the cam 105 mounted on the drum 104 engages the toe 103 of the lever 101 and thereby rocks the said lever and consequently raises the lever 90 once each course during and high l the knitting of the double sole and high splice. At the beginning of the klllttlllg of the double sole and high splice. thetoe 31 of the lever 32 drops, due to the spring 51 acting upon the lever 49, into engagement with the surface of the drum 25 at 29 and whereuponthe auxiliary cutting mechanism may be operated during the knitting of eachcourse b the means hereinbefore described and in- 1 c uding cam 62; and likewisewhen the lever 94 drops, due to the usual spring means not shown) acting upon the yarn lever 90, into engagement with the surface of the drun1'92 at 99, at the beginning of the knittingof the double sole and later at 100 at the beginning 'of the knitting of the high splice, the yarn lever 90 is then released from control of the drum lever 94 and as a consequence thereof may be actuated once each course by means hereinbefore described and including cam 105. However, when the

cams

27 and 28 rock the lever 32, the lever arm 45 is rocked which arm by engaging pin 48 rocks the bell crank lever 59' and consequently holds the movable yarn cutting element 81 in a closed position and so that periodic rotary movements of the cam 62 have no eti'ect upon the auxiliary cutting mechanisn r, the cam ()2 moving idly past the depending toe 49 of lever 49: and likeso wise when the lever 94 is rocked by earns 91 or 92 the reinforcing lever 90 is maintained in an inoperative, elevated position above the needles and while in such position the rotary movements of the cam 105 merely cause idle rocking movements to be imparted to the lever 101.

In Figs. 3 and 4 are shown two positions of the knitting instrumentalities. in one of which positions, Fig. 3, the splicing lever 90 4G is shown in feeding position and the leading double sole and high splice cylinder needle 108 about to knit in the splicing thread 88 together with the body thread 89, while the last double sole or high splice needle 109 is shown substantially diametrically opposite the needle 108 and carrying the float 13 of the splicing thread 88 within a V-shaped notch defined by the inner,lower edge 85 of the finger 83 and the upper, outer edge of the 50 companion cutting plate 84. In the other of said positions, Fig. 4, is shown the splicing lever 90 immediately after it has been raised to an inoperative position within the circle of needles in which position the advancing cylinder and dial needles do not engage and knit in the double sole and high splice thread 88 but knit in the body thread 89 only. In Fig. 4 the end needle 109 of the high splice and double sole series of cylinder needles is shown and, compared to its position in Fig. 3, is spaced therefrom, in the direction of the arrow, somewhat more than 180 degrees.

Upon continued rotation of the needle cylinder in the direction of the arrow, Fig. 3, the float 13 is carried by the end high splice and double sole needle 109 from the position shown in Fig. 4 around the needle c rcle above a pin 110 and finally to the position shown in Fig. 3, whereupon the movable cutting member 81 is actuated by the mechanism hereinbefore described, float 13 being severed and the severed end of the said float being temporarily retained, as will hereinafter be described, by a clamp which constitutes part of the main binder. Thereafter the leading high splice and double sole needle 108 carries the float, which extends from the said vneedle 108 to the auxiliary cutter, around the pin 110 as indicated in dotted lines, Fig. 3, whereupon, due to continued rotation of the needle cylinder in the direction of the arrow, the float is withdrawn in a more or less radial direction across the top of the dial cap 18. The floats 13 thus drawnr across the dial cap 18 by the pin 110 are caused to drop off the edge of the dial cap and dial at a point immediately adjacent to the said pin 110, whereupon continued rotation of the needle cylinder causes the said floats tofollow the leading high splice and double sole needle 108 in its movement of rotation around the needle circle and, due to gravity, the floats tend to drop behind the cylinder needles, that is, be-

tween the cylinder needles and the dial, the

companion dial needles being withdrawn and inactive. Substantially 270 degrees, more or less in the direction pf'rotation of the needle cylinder from the pin 110 a brush 111 is attached to the dial cap 18 as by screws 112. The brush consists of tufts of depending hairs or bristles 113, Fig. 20. When, due to continued rotation of the needle cylinder, the leading high splice and double sole needle 108 reaches a position adjacent to the brush 111 the bristles thereof engage a float 13 and force the said float below the dial cap 18 and dial 17 so that the dial needles 21 as they subsequently advance as at 114, Fig. 4, may engage and knit in such high splice and double sole float. Furthermore as the cylinder needles 23 are in the elevated position shown in Fig. 20 throughout the major portion of the needle circle the long floats 13 are prevented from passing in front of the needle hooks where they might be knitted in by the said cylinder needles.

In Figs. 15, 1(3 and 17 is disclosed an auxiliary cutting mechanism modified somewhat from the specific form of cutting mechanism hereinbefore disclosed for severing the high splice and double sole floats 13. The mechanisms disclosed in said Figs. 15, 16 and 17 not I are controlled in the same manner andthrough the same connections as are the corresponding mechanisms hereinbefore de- "scribed and where the parts are unmodified the same reference characters are adopted as are used in connection with the disclosures Pivotally connected to the link 66 is a lever 1-15 substantially identical with the corresponding lever 68. A sleeve or tubular extension 116'which connects the two arms of thelever extends to and rests upon the upper surface pf the dial cap 18' and is mounted for turniiig movements upon and is retained in dsition by means of a pivot pin or screw 11'? which latter, at its lower end, is in threaded engagement with the dial cap 18. An arm 118 of lever 115 is provided with an elongated slot 119 adjacent to the outer end thereof through which passes a pin 120 the other end of which is threaded and screwed into a threaded opening in the upper and movable member 121 of the cutter.. A coil spring 122 is interposed between the under face of the lever arm 118 and the upper face of the movable plate or blade 121, whereby the said plate is maintained in position against a second plate 123 which constitutes the fixed element 01'. blade of the cutter. The dial cap 18 is recessed as at 124 within which recess the plate 123 is fixedly retained by means of a pin or screw 125 which also serves as a pivot for the plate 121. During the knitting of each course as hereinbefore described the link 66 is shifted and such shifting of the link '66 is communicated to the lever 115 whereupon the pin and slot connection 119,

'120 moves the plate 121 upon its pivot 125 thereby to swing the said plate to and from the open or yarn receiving position shown in Fig. 17 which position corresponds to the position of the plate 81, Fig.3.

In Figs.18 and 19 further modified means for cutting the high splice and double sole floats are disclosed and wherein a link 66' corresponding to but not identical with the link 66 is pivoted to a bell crank lever 126 b means of the detachable connections specifically disclosed in Fig. 14. The bell crank lever 126 is pivoted at 127 to a bracket 128 in turn depending from and connected to the dial sup orting bracket 129. To the other arm of tlie bell crank is pivotally connected at 130 a link 131 to which is pivoted, at its other end at 132, a movable element or blade 133 of an auxiliary cutting mechanism for severing the high splice and double sole floats 13. The dial cap 18' is recessed as at 134 thereby to provide room for the movable element or blade of the cutting mechanism and at the same time to present an inclined, fixed cutting edge 135 adapted to cooperate with the lower cutting edge of the movable cutting member 133. The movable member 133 is pivotally connected intermediate its end by means of a pin or screw 136 to an upstanding block 137 which constitutes part of the dial cap 18'. The pin or screw 136 also serves to retain a spring 138 in position against the outer face of the movable element 133 and thereby retain the latter in position so that the cutting edge thereof may register properly withtlie cutting ed e 135. A pin 139 carried by the movable e ement 133 engages in a slot 140 formed in the spring 1258 thereby preventing the latter from turning on the pin 136. A pin141 upstanding from the dial cap serves to guide the floats 13 of the splicing thread. 4

In Fig. 19a portion of the dial 17' is shown broken'away as at 142. The dial is radially slotted as usual, one of which slots is shown at 143. The dial walls which separate and define therebetween the slots 143 are provided with upwardlyextending spacing fins or projections 144 which constitute a flange on the, dial'whereby to close the gap between the under face of the dial cap and the upper face of the dial. If no such provision is made the floats 13, which are carried around by the rotation of the needle cylinder'as hereinbe-. fore described, may be drawn over the tops of the dial needles as they are advanced Figs. 4 and 18, to take thread and knit. onsequently the fins or projections 144 serve the purpose of closing the space otherwise formed between the upper face of the dial and the lower face of the dial cap thereby reventing the floats 13 from being caught an knit in by the dial needles as they are projected and later retracted.

As hereinbefore stated the pin 110, in conjunction with the brush 111, functions to cause the floats to pass downwardly between the backs of the cylinder needles and the dial. Ordinarily the pin 110 in conjunction with the brush 111 serves the purpose but occasionally a float 13 may be laid over and engaged by dial needles as they are advanced and in order to avoid 'such possibility the space between the upper face of the dial and the lower face of the dial cap is filled in by 105 means of the projections 144 which constitute continuations of the needle walls.

Although shown in connection with a modified form of cutter, Figs. 18 and 19, never-the-' less the construction of the dial for the purno pose just described is also applicable to dials and dial caps having mounted thereon the forms ofauxiliary cutters shown specifically in Figs. 5 and 16.

In Figs. 21 and 22 is disclosed a means 115 which, although it may be used in conjunction with the pin 110, is preferably used alone, that is, without the pm 110.

In addition to the auxiliary yarn severing mechanism hereinbefore described the usual 12 binding mechanism is used which includes an automatically actuated clamp 145 and a loosely mounted clamp 146 adapted lightly to tension the yarns or threads and retain them when the clamp 145 is raised to permit the 125 entry of a thread or yarn thrown out of action. and a cutter 147 mounted upon the upper face of the dial cap and automatically actuated in any desired manner. The clamp 146 additionally functions during high splice 130 and double sole knitting temporarily to re tain the ends of the long floats 13 until the leading high splice and double sole needles again knit the reinforcing thread.

Fastened to one face of the clamp 145 as by means of a screw 148 is a fork-shaped member 149 an arm 150 of which normally seats upon a stop pin 151 carried by and laterally extending from clamp 145. Whenever, dur ing the knitting of reinforced courses such as high splice and double sole, the lever 90 is raised to an inoperative position, Fig. 4, above the needles, the hereinbefore mentioned last double sole and high splice needle 109 moves in the direction f the arrow, Fig. 4, and finally carries the float to such a position that it passes into the space 152 provided in the clamp 145 and finally engages the outer face or edge 153 of the member 149 and upon continued rotation of the needle cylinder tilts the said" member 149on-its pivot 148 whereupon the float 13 is trapped or held within the space 154 defined by an arm of the member 149 and the clamp 145. The member 149 after the float passes thereunder immediately drops until the arm 150 engages pin 151. Thereafter continued rotation of the needle cylinder causes the leading high splice and double sole' needle 108 (Figs. 3, 21 and 22) to carry the float against the edge 155 of the member 149 and pull the severed float 13 in a direction more or less radially of the dial cap and finally completely free from the clamp 145 as the said float 13 follows the needle 108 due to the continued rotation of the needle cylinder.

One important advantage of the use of the float trapping member 149 resides in the fact that, when the needle 108 draws the float 13 across the edge 155 of the element 149, it

does not disturb or tend to pull out from the binder other threads, two of which are indicated at 156 and 157 by way of example, because of the fact that the other threads are retained between the clamp 145 and the upper.

- ly in Figs. 15-19 inclusive.

In Fig. 23 is shown a modified construction of dial cap 158 which cap is provided withthe usual cams shown in Fig. 6 and is of a diameter slightly greater than the diameter of the needle dial 159, and connected to or formed integrally with the overhanging portion 160 of the dial cap is an annular flange 161 which overlaps the dial needle walls 162 as at 163 thereby to prevent the splicing or other threads from passing into the space 164 which separates the upper edges of the dial walls from the lower face of the dial cap or cams 165. The needle walls 162 are beveled as at 166 and the inner face of the flange161 is likewise beveled as at 167.

While the brush 111 and pin 110 or the yarn trapping means 149 serve to guide the floats of thread so that they will pass between the dial and cylinder, nevertheless unless the flange 161 or an equivalent means be provided the floats of threads may pass in between the dial cap and dial which is objectionable- A latch ring 168 as Well as a sinker head 169 and a sinker cap 170, which sinker cap is provided with cams for imparting radial movements to sinkers (not shown), are all mounted upon or carried by the frame of the machine in the usual manner and'cooperate with the dial and cylinder needles to knit the stocking or half hose disclosed in Fig. 1.

The needles may be divided, and thereby some of them selected to knit the reinforcing thread, in any suitable manner and by any suitable means, I either in conjunction with the half-course movements of the reinforcing guide, or independently thereof.

In some of the claims reference is made to rib fabric and plain fabric as being knitted simultaneously or, at the same time. By that is meant rib and plain fabric is knitted during the knitting of each reinforced course.

Although as hereinbefore disclosed, the invention is primarily intended for the production of stockings provided with ribbed insteps and reinforced portions nevertheless the invention in its broader aspect.may be utilized for the production of ribbed fabric other than hosiery having rib wales and adjacent thereto 1am Wales which latter are reinforced.

lthough it is desirable that the severing of the reinforcing thread or yarn be closely adjacent to the wales constituting the high splice and/or double sole, nevertheless the severing may occur at a point somewhat removed from the said high splice and/or double sole wales, the limitation adjacent being intended to mean a severing of the reinforcing thread somewhere between the first and last wales where the said reinforcing thread is knitted into the fabric. and preferably nearer to one side of the reinforced area than to the other side'thereof.

The machine hereinbefore specifically described and illustrated in the accompanying drawings discloses the preferred forms of mechanisms for effecting the knitting of the product disclosed in Fig. 1 hereof, although other types of knitting machines capable of knitting rib and plain fabric may be so constructed or modified as to knit the stocking or half hose disclosed in Fig. 1; in other words, the type of machine disclosed in the foregoing description and accompanying drawings, is

merely illustrative of the invention, it not being the intention to limit the claims otherwise than by the express limitations in the claims themselves. a

The invention hereinbefore disclosed is applicable either to a half hose or to a stocking of full length and although in certain of the claims reference is made to a stocking nevertheless there is no intention of thereby limitihg the invention to a full length stocking, the term stocking being used in a generic sense.
