' FLAT KNITTING FRAME Filed Nov. 18, 1938 JnvenI-or:
Patented Ma. 5, 1940 Max Nebel, Chcmnitz, Germany Application November 18, 1938, Serial No. 241,256
In Germany June 18, 1935 a 3 Claims. (01.66-91) This invention relates to a device for producing two-threaded knit fabric having sinker loops of different length, as plush-loop fabric, on a fiat knitting machine; In order to produce plush-loop fabric, and particularly the kind provided with plush loops above each sinker loop, it has been proposed to fit both the jack and dividing sinkers with a plush throat arranged above and in front of the ground 10 thread throat. As it is not possible after two threads have been drawn out at different lengths to divide also at different lengths by means of dividing sinkers equipped with plush throats, this proposal is limited to flat knitting frames having no dividing sinkers. loop fabric having plush loops above each dividing sinker loop on a 'flat knitting frame equipped with both jack and dividing sinkers, as a Cotton frame, it is known to divide the plush loops, which are longer than the ground-thread loops, by means of the upper edge of auxiliary sinkers moving during the sinking and dividing operations from the front between the frame needles and being positioned in front of the dividing sinkers, in downward direction by the descending frame needles. lnthe known type of flat or Cotton frame the second thread can be sunk into longer loops than the ground thread by means of jack sinkers having a plush throat, so that the plush thread is drawn out horizontally like the ground thread, but longer than the latter. The dividing sinkers of this type of machine possess either one throat or two throats separated by a nib, the upper throat being located exactly vertically, or approximately so, above the lower ground thread throat. In the latter instance, too, it is therefore necessary to divide downwardly.
To permit dividing of the longer plush loops 40 against the elastic needle shanks in the regular manner without employing an inelastic firm edge which dividing is performed ,by means of the upper edge of rigid auxiliary sinkers or of a nib Q provided on the dividing sinkers, the invention provides for sinking longer loops fromthe second thread not against the. shank ofthe needle but To produce plushagainst the front edge of auxiliary sinkers oneof which is arranged during the sinking operation 50 in front of each dividing sinker between the frame needles and at s'olow a level between them in the direction of sinking that, compared with the loops formed from the ground thread, the length of the loops sunk from the plush thread, measured from the front edge ofthe auxiliary sinkersbehind the needles to the plush throat of the sinkers in front of the needles, is twice the extent to which the sinker loops from the second thread are to be longer than the sinker loops the same as'that between the sinking point in a the plush throat and the sinking point in the ground thread throat of the jack sinkers, and the auxiliary sinkers, during the dividing operation, advance in front of the dividing sinkers and move out of the needle row when the dividing sinkers enter between the needles for division and thereby pass the loops drawn out longer behind the needles through them, so that the longer drawn out plush thread is divided against the needle shank to form loops that are longer than those sunk from the ground thread.
Flat knitting frames are known, in which a 0 second thread is sunk longer than the first against the edge at the free end of one or mm'e auxiliary sinkers, passing from the front through the needle row, instead of'against the shank of the needle. In this case, however, the thread drawn out longer is kept away from the needle shank until the frame needles move down to the press, and the longer loop does not pass under the needle point, but is cast ofi' toward the rear side of the fabric for the purpose of producing plated patterns. The loop portion drawn out longer is therefore not worked into a loop and not divided as according to the invention to form sinker loops that are longer than the sinker loops "of the ground fabric. The use of auxiliary sink- 335 er s passing from the front through the needle row ..for the purpose of'si-nkin'g longer loops is known also in the production of single-threaded common hosiery on'flat knitting frames and serves for working sinker loops of different width for patterning purposes.
as suggested by the older proposals according to' One form of the invention together with the loop-forming tools of a Cotton frame is shown in. the accompanying drawing, in which Figure 1 shows the position of the lo'op-forming tools during the sinking operation; v
Fig. 2 shows the position of the-loop-forming tools during the dividing operation;
Fig. 3 shows theposition while the frame needles move into putting-on position;
Fig. 4 is a top view of the loop-forming tools shownin Fig. v1;
Fig.5 is a top view of the loop-forming tools in the position shown inFig. .2; and
Fig. 6 shows the sinking position according '55 throat l and, above and in front thereof, a plushthread throat 1 having an approximately vertical lower edge 1 Between the: frameneedles 9 auxiliary sinkers H, one in front of every dividing sinker 1, are arrangedduring the sinking op eration. The upper edge H is located slightly above the top edge of the jack sinker and the lower edge II lies about level with the groundthread throat 6 The free end of the auxiliary sinkers II has a vertical or almost vertical edge I,
ll connecting below with the pointed portion l l having a horizontal upper edge H and a rearwardly and downwardly inclined lower edge i l. The end H of the pointed portion H and the upper edge ll are approximately on a level with the corners 6, 1 of the plush throat. During the sinking operation, Fig. l, the auxiliary sinkers II are so positioned between the frame needles that the second thread ii is sunk by the advancing jack sinkers 6 not at the needle shank but at the almost vertical edge l| at the free end of the auxiliary sinkers II. 'The edge ll of the auxiliary sinkers is located atapproximately the same distance to the rear of the needle shank as the throat 6 of the jack sinker 6 is positioned in front of the ground-thread throat 6 The ground thread I'- guided from the inclined lower edge of the pointed portion H of the auxiliary sinkers l l during advance of the jack sinker on the ground-thread throat S 'is sunk at the needle shank in the usual manner; The position of the thread is shown clearly in Fig. 4.
When the dividing sinkers l advance for the dividing operation, the auxiliary sinkers ll, always slightly in front of the dividing sinkers,
move out of the needle row and into the position.
shown in Fig. 2, so that the thread 3 is held between the edges H II of the auxiliary sinkers II and th inclined upper edge of the plush throat 1 of the dividing sinkers I until the dividing operation is completed. The excess thread of the loop formed from the thread 3"- cannot be displaced therefore while the auxiliary sinkers move out of the needle row and cannot jump out of the plush throat 1 The dividing operation is carried out so that the excess portion of the loop formed of the thread 3 which extends from the needle shank to the edge H of the auxiliarysinkers II, is engaged by the throat 1 of the dividing sinkers I, passed during advance of the latter through the needle row, and formed into a loop in the direction of the needle shank, the loop having the same length as the loops suspended in the plush throats 6 of the jack sinkers 6, as indicated in Fig. 5.
Fig. 3 shows the positionof the loop-forming tools during the descent of the frame needles and indicates that the loopformed of the second thread,-for instance a plush loop, can easily slide ofl from the almost vertical edge.
In the event of small diiferences in length between the ground thread loops and the loops formed of the second thread the throat 6 or 1 for the second thread is preferably provided with a vertical or almost vertical lower edge. When the difierences in length are, however, considerable, as for instance in the production of loopplush fabric, a nib 6 or I having a downward sloping upper edge (Fig. 6) may be arranged between the two superposed throats of the jack and dividing sinkers in known manner.
It is immaterial whether the thread guides are in their usual high position or whether the outlet of the ground thread guide is at the level of the ground thread throat and the guide for the second thread has its outlet on a level with the upper throat.
I claim:
1. A. flat knitting frame, comprising frame needles, jack sinkers and dividing sinkers, each of said sinkers having a ground thread throat, a
second throat located in front of the first throat, the lower throat of said sinkers sinking and dividing the ground thread and the upper. throat sinking and dividing a plush thread, auxiliary sinkers arranged in a bar in front of the needle row.
