This invention relates to cutters and clamps for knitting machines and more particularly to a method of operating a high splicing cutter and clamp for circular knitting machines having a dial. Cutters and clamps heretofore used for sectional splicing yarns have been located inside the needle circle below the throatplate in order that the yarn may get into the clamp as quickly as possible. In machines having dials there is not room inside the needle circle for a cutter and clamp at that level, and it is one purpose of the present invention be used in machines having dials. Another object of the invention is to provide a method of inserting the yarn which is quick and positive.

According to this invention the cutter and clamp may be set above the level of the needles at the throatplate in such a manner as not to interfere with the dial. sertion of the yarns by its own movement by forming a loop in the yarn and then ofiering that loop to the needles. According to this method the yarn finger is lowered to its feeding point before it is timeto insert the yarn, andthe cutter is raised from its normal position to a higher one before the yarn is inserted. This is done in such manner as to form a slack in the yarn and when it is time to insert the yarn, the cutter and clamp are merely dropped down nearer the yarn finger, thus throwing the loop of yarn in the path of the needles. The yarn is removed from the needles and given to the cutter and clamp by raising the yarn finger to non-feeding position, the raising of the cutter and clamp occurring before or after the removal of the yarn, as desired.

Referring to the drawings, there are the usual needle cylinder 26! with independent latch needles N vertically movable therein, yarn fingers F pivotally mounted on a stud 554 on the latch ring 550 which in turn is pivoted on the upright bracket llll on the 'bedplate-B of the machine. These yarn fingers are adapted to be lifted out of action and dropped into action by the usual, thrust rods 460 operating from cams on the surface of the main pattern. drum l2ll,.as usual. Suspended above the needle cylinder 2" 2 sectional ter bracket [61,

-foot stockings or I necessary to provide a special cutter and clamp.

by means 01 a bracket II fastened on the latch ring III is a dial spindle d carrying a dial D ,which carries secondary knitting instruments N and the ordinary cutter c' and clamp c (Fig. 2).

In order to cut and clamp successfully yarns which are thrown into and out of action frequently at borders oi predetermined segments of the fabric, such for instance as in the case ofsplit high splicing at the heel, it is Heretoi'ore, these cutters and clamps for sectional being set at a point below the level of the'needles' any circular as they pass the throatplate. In knitting machine having a dial, such for example as the machine shown in the U. S. patentof Robert Scott 1,641,554, there is not sufllcient room above the dial for the sectional splicing cutter and clamp such as has been heretofore known.

In the example shown in the drawings the new splicing cutter and clamp is carried stud III lying outside the yoke of the, latch ring III. The cutter and clamp proper consists of a slotted frame-I94 from whichthe cutting blade 1I| and the clamp blade 185 project inwardly and downwardly over the needles. Between and on either side of the cutting and clamping blades are guide members "I held fixedly in the frame by a cover plate I87 (Figs. 4, 5 and 6).

ting and clamping blades have hooked for- V by an operating lever lll pivoted at X on the cutand connected to the feet 184' and III of the blades. The operating lever is actuated by the following mechanism from a neripheral cam 295 onthe usual sinker ring revolv hold the finger 78 3 ing with the needles. There is a swinging arm "8 carrying a finger 1B3 engaging the cam 296 and a wire "9 connected to the operating lever I11 and passing through the free end of the against the cam 296, the spring being stretched between the cutter and clamp bracket 16'! and a collar 1M on the wire 119 near its mid-point. This spring serves to open the clamp and cutter when permitted by the cam 296.

When the machine is knitting portions of the stocking where sectional splicing is not being done, the sectional cutter and clamp can be raised out of action from the main pattern drum in by a rearwardly extending arm 168 on the bracket I61. This arm 168 is connected to athrust rod of this cam lever lies in one 01 the cam paths on'the main pattern drum I20. When the cam lever 710 rides up on a cam held by the main cutter and clamp c' and c.

It is necessary that the sectional cutter does 'not' operate except during sectional splicing. For this purpo ring III lying Just in front of the operating lever course, loopers rounds and toe are made in the made isthe foot which has a spliced sole.

there is a lug III on the latch I put the collar 182 in 'a position such that swinging of the arm llI caused by the cam 296 will be inefiective to move the wire "9 and the lever (11. In such position the cam 296 does not operate the cutter and clamp. This prevents yarns in-theinactive yarn fingers from being severed by this cutter while out of action.

ter bracket I61 and resting on .top of the latch ring 550 opposite the usual throatplate 559; To raise and dip the cutter and clamp the dial reyolving in time with the needle cylinder is availed of. On the bracket "I61 slack and then dropping the clamp, thus pushing the loop of yarn down into the path of the needles. I l

The sectional splicing yarn finger may be actuated through its thrust rod 460 by mechanism and described in the patent to Robert W. Scott dated July 30, 1918 Number 1,274,338. To insure that the ends of the sectional splicthrough to the right side of the finished fabric, a brush 188 is placed near the needles at the knitting point, this brush tending to sweep the ends of the yarns inside the needle circle. order that this brush may be taken out of action when the sectional splicing cutter and clamp of the cutter bracket 161 will cause the brush 188 to be pulled out of contact with the circle of needles.

Having now described the construction of the 65 novel parts of the invention, the operation of ,the Assuming that a-stocL ing is being knit from toe to top, the starting up" usual manner.

The next piece of fabric to be the peripheral cam 296 I clamp does not interfere in any way with the and clamp are down in their lower position over the needles. The arm. 15H also allows the spring 192 (Fig. 3) to swing the brush 188 into position for action. The same movement of the main pattern drum I20 causes the thrust rod controlling the splicing yarn finger to drop down and the splicing yarn to be fed to the needles beginning on the sectionalneedles having low butts in the well known manner (Fig. 7) After the segment of the needles knitting the sole of the stocking have taken the yarn, the splicing finger is lifted put at the last medium buttneedle and the splicing yarn is raised into and caught inside the hooked forward ends of the cutter blade I84 and clamping blade I85 (Figs. 8 and '13). At this point thefinger 183 of the swin g arm I18 come in'contact with the leading end of the peripheral earn 296 causing the lever 111 to withdraw the cutter blade I84 and the clamping blade 185 into the guide members 186 cutting and clamping the yarns (Fig. 9). The cooperation of the clamp and yarn finger in offering yarn to the needleswill now be set forth.

Whenthe revolution ofv the needle cylinder brings the first needle which is to receive the splicing yarn on the next course about 1 inches away from'the splicing finger, that splicing finger is dropped down into operative position by its thrust rod Mill and simultaneously the cam 113 on the dial spindle causes the cutter and clamp to be raised about of an inch (Fig. 10). This raising of the cutter and clamp could have been caused before the yarn finger was raised, if so desired. This movement draws an extra length of yarn between the yarn finger and the cutter and clamp. 'At'this moment the yarns 'are passing above the needles at the throatplate. The adjustable link I'll rides of! the cam 11! on the dial spindle it just in time for the cutter and clamp to drop down and throw a loop in front of the first needle which is to take the splicing yarn. (Figs. 11 and 14).. The finger III then rides off and the yarn is released to be knit in (Fig. 12). This loop-throwing yarn 1 cutter and clamp is so active that it is not necessary to separate the needles into difierent levels to insure the sectional splicing yarns always being fed to approximately the same needlw but themechanism required for the new cutter and provision of means to thus separate the yarns :into additional levels if desired (see Fig. 11).

FromFigure 14, which shows the yarn inserting positions of the yarn finger-and clamp it will 1 be seen that the length of yarn between theyarn engaging portion of the clamp and the eye of the yarn finger is greater than the spacing between said portion and eye, and that therefore a loop 'of yarn existsbetween them and extends into the path of the needles. The manipulation of the yarn finger and clamp previous to their arrival at their respective yarn inserting positions are for the purpose of drawing such a length of yarn between them.

The cycleof operations just described continues until the heel is reached at which .point the cam lever 11!] rides up onto its heel cam 582 which raises the cutter and clamp and the bracket 'Iil entirely above the latch ring bracket 55' making it possible to manipulate any gap closing. ring. This raising of the sectional cutter and clamp preferably takes place just before the high. splicing yarn finger islifted out in order that the regular cutter c and clamp c mounted on the 7 19,995 latch ring bracket 550 in which position the cutter reinforcing yarn is. cut and clamped as previously described. The ends of the reinforcing tween the cylinder into a loop in the path of .the needles.

dial cap may cut and hold the sectional splicing yarn until sectional splicing is resumed. The raising of the .cutterand clamp also swings the brush I88 away from theneedle circle and pushes the lever Tll until the finger 183 cannot operate the sectional cutter. It might be noticed also that this lifting of the cutter and clamp also causes the adjustable link I'll to be withdrawn from contact with the cam 11! on the dial spindle thus obviating any possibility of the link catching on the cam during reciprocating knitting in theheelortoeasthecasemaybe' The heel is then knit and the yarn cutter bracket 'Ii'l bro ught down into operative position again as atthe beginning of the foot for knitting 15 of the high splice above" the heel pocket. The operation of the parts during the f ormation of the high splice is essentially similar to .that when making the spliced sole on the foot and will be obvious to any one skilled in the art.

In the knitting of the reinforced portions of seamless ribbedhosiery on the machine shown in the drawings the reinforcing yarn is applied to plain knitted portions. The reinforcing yarn may be supplied to the leading needle of the plain knitted portion as shown in Fig. 16 and withdrawn after being supplied to the other end needle of the plain knitted portion as shown in Fig. 15, although the reinforcing yarn is not necessarily supplied throughout the full extent of the plainiknitted portions. After being withdrawn from the needles, the reinforcing yarn is floated between the last needle knitting the reinforcing yarn and the yarn finger until the yarn in each course are swept by thebrush beand dial needles inside the needle circle.

The advantages of this novel method of and 40 mechanismfor inserting yarn will be obvious to those skilled in the art, and I do not wish to be limited in the uses to whichit may be put.
