FLAT RIB KNITTING MACHINE Filed Dec. 10, 1935 B WULDEMAR HEINITZ y ATTORNEY Patented Feb. 22, 1938 UNITED STATES FLAT RIB KNITTING MACHINE Waldemar Heinitz, Chemnitz, Germany, assignor to Schubert & Salzer Maschinenfabrik Aktiengesellschaft, Chemnitz, Germany I Application December 10, 1935, Serial No. 53,811 i In Germany December 10, 1934 1 Claim.
The present invention relates to flat rib knitting machines for the manufacture of tuck loops or tuck wrap loops.
Tuck loops are obtained hitherto upon flat rib knitting machines by the fact, that, by means of presser'plates, presser combs or the like, a number of frame needles are, according to rows, not pressed or prevented from moving into the range of the presser. patterning was limited to repetition according to rows.
Tuck wrap loops are obtained hitherto upon flat ri'b knitting machines by the fact, that the thread or wrap guides of the Jacquard apparatus each present their thread to at least two frame needles which thread is then sunk without a ground thread being presented to the frame needles, whereupon the needles, carrying this thread, are pressed by a common presser, so
that closed continuous rows, of tuck wrap loops are formed.
The present invention allows 'an increase of the patterning possibility of the tuck loopsas well as the tuck wrap loops, as individual tuck 5 loops may also be formed as tuck wrap loops at any desired points of the row of loops.
To obtain the desired object, special press in- -struments are provided which, by means of a special Jacquard roller or by means of the Jac- .quard roller already present for producing plating wrap loops; are brought into or withdrawn from the range of the heads of the frame needles. The special press instruments are then by the general presser pressed against the frame 3-.) needles, whereby by. the frame needles, not
pressed under pattern control, tuck loops according to pattern are obtained, and whereby pressing under pattern control of the frame needles carrying thread is obtained when forming tuck wrap loops, so that tuck loops and tuck wrap loops respectively are produced.
In this manner," tops or rib tops may be formed in-the row of loops of which any desired tuck patterns may be obtained, or any desired tuck wrap patterns may be produced in the row of loops if no tuck patterns are formed. The
tuck wrap patterns may, furthermore, be combined with wrap loops. These different. kinds of patterns, i. e., tuckpatterns, tuck wrap patterns or plating wrap patterns may then alternate successively and among one another respectively in the direction of the wales.
In plan rows of loops in which no tuck patterns and no tuck wrap patterns are formed,
3 no press instruments are shifted into the Consequently, this tuck of the 'presser by means of the Jacquard apparatus.
It is also of no importance, whether the Jac- 15 quard apparatus is arranged for a single group of thread or wrap guides or a Jacquard apparatoe with a plurality of groups of such guides is used.
In the accompanying drawing some embodi- 20 ments of the invention are shown by way of example.
In this drawing:
Fig.1 is aside elevation, partly in section, of as much of a fiat rib knitting machine as is nec- 25 essary for explaining the construction and op-. cration of the arrangement according to the invention,
Fig. 2 is a broken away' diagrammatic side elevation showing the individual parts of the de- 3o vice according to the invention in the position they occupy in the moment of pressing,
Fig. 3 is a perspective view of the press instrumentsalso in the position they occupy in the moment of pressing, 35
Fig. 7 is a diagrammatic side elevation of a.
constructionaccording to which the individually movable frame needles are, under pattern control, brought into and out of the range of the presser.
In all figures, one bank of needles only is shown, the other bank being omitted for the sake of simplicity.
In the construction shown in Figs. 1-4, I are the frame needles and 2 the thread or wrap guides. These guides are operated by the Jacquard card 4 led around the Jacquard roller 8. 8 are the jack sinkers and 8 is the general presser in the range of which the press instruments 8, 8' may be brought which are guided in bearings I. The press instruments 8, 8' are, by means of springs 8, held in a withdrawn position and may be brought into operative position by a Jacquard card I I led around a special Jacquard roller l8.
Fig. 2 shows a press instrument, the general presser, the frame needle and the jack sinker in the position they occupy in the moment of pressing; Fig. 3 illustrates in a perspective view the same position of the individual parts.
The thread or wrap guides 2 are actuated, in a well known manner, by a Jacquard card 4 led around the Jacquard roller 8.
If tuck loops are to be formed upon the frame needles I, the portion of the press instruments proper of the device operates only. By the Jacquard card ll (Fig. 4), led around the special Jacquard roller l0, the press instruments. 8, 8 are brought into the operative position. These press instruments are, by the general presser 8, pressed against the frame needles Ifso that plain loops are formed at these needles. 0n the needles, not pressed by the press instruments, tuck loops under pattern control are produced.
If, however, tuck wrap loops are to be formed upon the frame needles in which case no ground thread is presented, the wrap or thread uide apparatus as well as the press instruments, 1. e., the whole device, are required. The frame needles I are fedwith thread by the thread guides 2. By a Jacquard card ll (Fig. 4), led around the special Jacquard roller l8, press instruments 8, 8' are brought into operative position. These press instruments are again pressed against the frame needles I by means of the general presser 8. By pressing the needles, carrying thread, tuck wrap loops under pattern control are obtained.
According to Fig. 5 a double Jacquard apparatus with several groups of thread guides is used. It has been supposed, that two groups of thread guides are provided. Accordingly the Jacquard card l8, l ed around the Jacquard roller 8, must beprovided with two rows of perforations for the two groups of thread guides. It has been supposed, that also the press instruments 8, 8' are actuated by the same Jacquard card. The press, instruments 8, 8 are actuated by thrust heads l2, l2 provided at the ends of arms l8 of double-armed levers I8, I 4 which are pivotally mounted upon a shaft ii. The other arms ll of the double-armed levers l8, l4 cooperate with slides i8 actuated by the Jacquard card l8. As
shown in Fig. 6, the Jacquard card I8 is provided not only with the two rows of perforations necessary for actuating the two groups of thread guides, but also with a third row of perforations.
If the Jacquard roller 8 is moved against the thread guides 2, the latter are, underpattern control, brought into the operative position. If the Jacquard roller 3 is moved in the opposite direction, the Jacquard card acts upon the slides l8, so that, as long as perforations are not present in the third row, the double-armed levers l8, H are shifted and the press instruments 8 acted upon by the thrust head l2 (Fig. 5), are brought into the range of the frame needles i. If, however, a perforation is present in the Jacquard card, the slide I 6 enters. this perforation, so that the double-armed lever l8, l4 remains in its po-' sition and the thrust head l2 (Fig. 5) does not shift its press instrument 8'. g
If a simple thread or wrap guide apparatus is used as shown in Fig. 1, the thread guides may be actuated by the Jacquard apparatus acting upon the press instruments, instead of using a special Jacquard apparatus. tion of the double thread or wrap guide apparatus is shown in Fig. 5. The Jacquard card must then be provided with two rows of perforations one of which acts upon the thread guides on movement of the Jacquard roller against the thread guides, whereas, by a movement of the Jacquard-roller in the opposite direction, this roller acts with its second row of perforations upon the slides actuating the press instruments. I According to the construction shown in Fig. 7,
it has been supposed, that the frame needles I l are individually movable. The arms 28 of double- armed levers 28, 28 engage the feet of the frame needles I. The double- armed levers 28, 28 are pivotally mounted upon a shaft 88. The other arms 28 of the double-armed levers 28', 28
' are actuated by the slides 8|, which are influenced by a card 88 .led around the Jacquard roller 82. By this arrangement also the individually movable frame needles may, under pattern control, be brought into and withdrawn from the range of the presser 8. I
What I claim is:
A flat knitting machine substantially for the purpose set forth, comprising frame needles, a
' general presser, press instruments, wrap guides and a horizontally movable Jacquard roller acting upon said press instruments and upon said wrap guides. 1
