.ALBIN WINKLER, 0F PETROGRAD, RUSSIA, .ASSIGNOR OF ONE-HALF T0 ROBERT LEIBFRIED, OF PETROGRAD, RUSSIA.

KNITTING-MACHINE.

Application filed August 5, 1913.

Be it known that I, ALBIN IVIXKLRR, a subject ot' the Emperor of Russia, residing atlolpinskaia 27, Petrograd, Russia, have invented new and useful Improvements in Knitting-Machines, of which the following is a specification. t

The present invention has reference to a knitting machine employing bearded rneedles, and having two needle rows, for

making flat or tubular fashioned goods.

The machine is, accordingl to this invention, furnished witlrtwo loop sinking devices for the two needle rows, which devices can be-adjusted to change their position in relation to the needle rows whereby the formation of the meshes may be carried out by either 'rt' the needle rows, or'by both.

In the production of flat goods, z'. c. plain work on one needle bar, the yarn threads are always looped on one and the same row of needles; but in making tubular (plain circular) goods, the looping ot' the yarn threads is performed on both needle rows alternately; and in the case otl reversible goods the mesh is made, in general, on one needle row, though it can be made on both rows alternately.

In order to admit of the already mentioned changes in the position ot' the loop sinking devices in relation to the needle rows being effected, the loop sinking deviees-which will hereinafter be termed the swing headsare made capable of tilting. To this end, the said swing heads are arranged parallel to and facing each other. in, for example. a box-like frame, which is rotatably mounted so that it can swing on pivots. IVhen moved in this manner, one swing head moves away from its needle row, while the other swing head approaches so closely to its corresponding needle row as to be able to work in conjunction therewith.

'The term swing head means the loop sinking device required for each oppositel)7 situated needle row. Said device consists particularly of the jack sinkers mounted in such head. the falling bal', the jacks, the Shu-cocks. the slureoek bar. and the slureoek race. The present machine accordingly consists ot' two rows ot' jack sinkers for the two needle rows, together with` in each case. one loop sinking device composed ot' the members previously specified. In addition,

Figs. 11c and 1l are detail views of the slurcock pusher. to illustrate the changing over. Fig. 11g shows the swing head in the opposite position to that shown in Fig. 11. Fig. l2 illustrates the operation in narrowing'.

The machine illustrated in the drawings has two swing heads, in which the jacks 101 and 102, as well as the other loop-sinking members, are mounted. In knitting machine construetion these loop-sinking devices in general are termed heads especially in machines of the Cotton type. These two heads are built into the box 13, which is adapted to be turned about the axis 1S, as hereinafter described, so as to change the position of the heads with relation to .the frame needles, as can be seen by comparing Figs. l1 and 11b'.

The two needle bars 59 and G0 (Fig. Il) which are provided with bearded needles 59n and 60a respectively, slope toward each other after the manner of a straight knitting inachine, and are adapted to move up and down" over inclined surfaces 16 and 17 of a tres'tle frame 18, in order that they may describe the requisite forward and return strokes for making the loops and knocking them off Above the said two needle bars lie the par-` needle bar 60. The machine is also pro` Ivided with two pressers 74 yand 75 (Fig. 11)

- for the needles 59a and 60a, the thread-guide 131 with the bar 2O and the known narrowing devices 119 and 120 (Fig. 12).

In a manner similar to a Cotton knitting frame, but doubled, there are provided for operating the working -tools of the present knitting machine, twocain shafts .2 and 3, a. sinker-lever shaft 8i. (Fig. 11X), two needle-lever shafts 51 and 52 (Fig. 8), two tickler-lever shafts 123, 124 (Fig. 12), a presser-lever shaft (Fig. 11X), a changemotion shaft 6 and a bottom shaft 12 (Figs. 1 to 3). The rotating cam shafts 2 andA 3, which ai'econnected together by pinions 4 and 5, are rotated by means of any suitable driving mechanism (not shown in the drawing) which is caused to engage with the pinion 4.

In the cams on the shafts 2 and 3 the curve for producing the requisite operative movements of the members subjected to its infiuence, extends half way around the ein cuinfei'ence, and `is duplicated, there being one such curve on `each half of the cani. This enables work tov be carried on either of the two rows of frame needles-alternately, or on one and the same row of needles continuously', without changing the speed of the shafts 2 and 3,

The loop-forming device is operated by an arrangement similar/to that used in theA Cotton knitting machine. A pair of cone wheels 28, 29 (Figs. 2, 3, 5 and 6) set in rotation by the shaft 2, cause the sinker cam 26 to rotate, this acting on rollers 148 and 14:9 carried by a bar 152 which is suspended from a bar 33 by means of arms 154, 155 loose on said bar 33. The bar 152 is moved endwise by the sinker cam 26 the arms 154, 155 movingr therewith to and fro on the bar 33) and imparts a corresponding rockying movement to a lever 27 which is fulcrumed at 27a and connected with the arm 155 by means of a bolt 1'56. carries with it the sinker bar 19, on which isrloosely supported a driver 157 (Figs. 6, 6- andd) that is connectedl bybolts 158, 15.9 with bars 117, 118. The bars 117, 118

The lever 27 -b are respectively connected with the 'guide boxes 150 and 151 of the slur-cocks 150x, 151". When the sinker bar 19 is movedI longitudinally by lever 27 as described'one or the other` of two rings 160, 161 adjustably secured on said bar will come into Contact with the driver 157 and by the connections just referred to -effect an adjustment of the guide boxes 150, 151 and the slurcocks 150x, 151x on the uide bars 109, 110 therefor. Simultaneous y the thread guidey 131 (Fig. 11) will be shifted 4by Ameans hereinafter particularly pointed out. At the termination of the movement thus caused by the action of ring 161 on the driver 157, the sliders 115, 116 of the slurcock pushers will be brought into contact with bell cranks 22, 23 and by the contact of the lower of said bell cranks with a knocker 25 the sliircocks will be caused to extend in opposite directions vertically. The operating device for thelatter is explained later on. Y.

The machine works in the following manner vl. Plain. tubular gouda-Before commencing 'a fresh row of loops, the box 13,- with the two swing heads, is arranged in the horizontal position, shown by dotted lines in Fig. 11, which position will'be hereinafter called the bottom position. In this position the rollers 10 and 11 of an anchor shaped meinber 7 (Fig. 4), which is temporarily in a vertical position, make coiitact with juxtaposed slaiiting surfaces of cams 3l and 32 on the shafts 2 and 3. The needle' bars'59 and 60 (Fig. 8) are in their lowest (knocking of) position, while the cams 53.21Iid 54 iliade coritact by means of the most prominent porlolo tions of their peripheries, withthe rollers of the levers 55 and 56 which operate the needle bars. In th aforesaid bottom position a sinker cam 85| Fig., 9) is in contact, by ineansof its prominent peripheral section 85 (Fig. 9), with the rollerv of a lever 86, mountedon a shaft 84, so thatva lifting sur face 87 (Figs. 11x, 11") is raised, together with bars 88 and 89 (Figs. 11 and 11") and the swing-head push bars 92 and 93 which bear against said surface by means of set screws 113, 114, 121, 122 '(see Figs. 11, 11a, 11, 11X). By this means the two swing heads and their falling bars 90 and 91 (Figs. 11 and 11)-as also the Sinkers 99 andlOO situated thereon-are raised to the top position (Fig. 11, dotted lines). A presser: cam 66 (Fig. 1 0) mounted on the shaft' 2, as-

sumes sucha position-in the said bottom position of the members-that its extension 66 is 135 behind the position'shown in Fig. l0. in a direction opposite' to that indicated Shown in its left hand position in F ig. 6 is on the right when the members are in the said bottoni position, while the sinker lever 27, instead of being in the inward position y the arrow. The suiker cam`26, which is 'i shown in Fig. 6, has also swung to the right under the action of said cam.` If now the shafts 2 and 3 be turned through 15 in the direction of the arrow in Fig. 4, out of the said bottom position, then the operating members take up the position represented in Fig. f1, 1n which the raised portion of the cam 32 makes contact with the roller 11, and the recessed portion of the cam 31 makes contact with the roller 10. The anchor 7 is consequently moved in toward the shaft 2, that is to say toward the right, and this movement is transmitted through a quadrant 9 and pinion 8, on a shaft 6, and also through a bell-crank 'lever 135 with draw ',bars 14 and 15, to the box 13 which also turns over toward the right. By this tilting movement of the box 13 toward the right, the slurcock pushers 115 and 11G (Figs. 11, llf) are displaced by means of one of the slurcock bell cranks 22 and (Figs. f1, 4 and 6d)connected together by means of a' shaft 24e-coming against it-s corresponding striker 25 (Figs. 1 and 4), in such a' way that the slurcocks are reversed, the slurcock of the one row of Sinkers being thrown out of action and that of the other row of sinkers thrown into action. At the saine time the right hand swing head sinks in consequence of the push bar 92 (Fig. 11),

,which carries it, sliding (by means of the roller 92a (Figs. 3, 11, 11c and 11X) mount,1 ed on its end) over the concentric track 107( of a heart-shaped member 94 (Fig. 11X). The push bar88, which carries the falling bar 90, and whose roll 88El leaves its path on the outer edge of the heart-shaped member 941, as the latter-.has made a rotation through 15, is caught by the lifting surface 87 and descends with same. since the cam 85 of the shaft 3, (Figs. 9 and 110) glides by the roller 86a onithe lever 8G up to the point marked :n in Fig. 11b. 0n the Shafts 2' and 3 being turned through another 30 the lever 8G of the shaft 84 (Fig. 11b) swings down into its lowest position, corresponding to the position of the cam 85 of the shaft This movement is followed by the lifting surface 87, together with the push bar 88 and the falling bar 90 (Fig. 11). The right hand swing head, however, cannot follow this movement, since its push bar 92 is resting, by means of its roller 92, against the track 107 on the heart-shaped member 94 (Fig.

11). At the same time the left hand swing head and the corresponding,falling bar are held in the top position bv means of the heart-shaped member 94. By means of its roller the needle bar lever of the f shaft 51 (Fig. 8) makes contact with the recess in the needle cam 53 of the shaft 2, so

that the needle bar 59 is raised into the top position by means of its pushbar 57. The needle bar is 'kept down 1n its bottom position (Fig. 8) bv means of a draw bar 61 of the anchor 7, engaging with the arm 56. In this way the anchor 7 with its draw bar 61 brings one cam-half out of action. alternately in front and rear, and causes the working movement necessary for producing tubular goods to be performed. A further rotation of the shafts 2 and 3 through Gt" causes the formation of the meshes. As already mentioned, the sinker cam 2G Fig. 6') and the sinker lever 27 were in position on the right, so that, after the sinker cam 2G had been turned through 1050, the sinker lever 27 took up the inward position shown in Fig. 6, .and the sinker cam 2G the corresponding position on the left. The sinker draw bar 19 (Figs. 2 and G), mounted in the swing-head box 13 and connected to the sinker lever 27, is thereby pushed toward the left (Fig. (S). On this sinker draw bar is situated a brake bearing ring 136 (Fig. 11) with which is connected a brake 132 sliding in the groove in the sinker bar and engaging, b v means of a spring bolt 133, in a \recess in the sinker bar. This brake 132 in turn, by means of a nose 134, operates the thread-guide bar 2O (Figs. 4, 11 and 11) which carries the threadt guide 131. The slurcocks 150 and 151 are also cnnected t0 this sinker bar 19 through theV bars 117, 118 and driver 157 which slides between the set rings 160 and 161 shown in Figs. (i, (3"

and 6, so that a suitable distance is maintained between the slurcocks and the thread guides 131 as is necessary in every stocking frame. In this way, after the shafts 2 and 3 have been turned through (30, the slurcocks and the thread guide come into position on the left, in which position the thread is laid in the needles of the needle bar 59 (Fig. ll) by means of the sinkers 99, which are lowered by the slurcocks 150 in the known manner. Tlie thread guideis now arrested by the stop 21 (Fig. 4b) which engages, by means of a pin 21il in a groove in the thread-guide bar 20. If necessary this stopping of the thread guide can be suitably adjusted by altering the position of the stop 21 by screw 21, On the shafts 2 and 3 being rotated thro-ugh another 300, the needle bar 59 is drawn back by the cam 53 through the needle bar lever 55 (Fig. 8) by the aid of the draw bar 57, to such a distance that the points of the needles stand close in front of the ware. The work of the presser 74 (Fig. 11) now begins. The presser cam GG (Figs. 2, 3 and 10) now takes up such a position in relation to the lever (i7 (Fig. 10) as to force the presser push bar 72 (Fig. 11) upward by means of the transmission members GS, 69, and 71 (Fig. 11")` and of the adjustable screw 82 (see Figs. 11a, 11) and to force down the presser 74 bv turning it about the pivots 76. The needle points of the needle bar 59 are thereby closed, whereupon the needles continue to retreat a short distance, so that the old meshes slip down off the closed needles and new meshes are formed. The corresponding position of the members is shown in Fig. 11. The other presser 75 takes no part .in the'described operation, being out of its working position.'

There next ensues a further rotation of the shafts 2 and 3 through 45. .At this point,

since the falling bar push bar 88 bears, byl means of its set screw 113, against the l1 t-' an 1nch above the lifting surface 87,'coming into action later while the falling bar 90 receives its forward impulse. The sallent portionof the sinker cam 85 (Flgs. 9,

11) has not yet come fully into action, the

remainder serving to effect the now ensuing .total lift of the falling bar 90 and right being 'made swing head when plain one-side goods are In the' case of the tubular goods now in question, however, the box 13 is lifted, on which account the set screws 113 and'.l,%- move out of reach of the lifting `surface 87 (F ig;y 11X), the lever 86 making an idle stroke. The falling bar and swing head are-now operated by the heart-shaped memberf94 (which therefore takes over the final functionof the sinker cam). This 'completes the formation of Iarow of meshes on the needle bar 59. In order that the same series of working operations may be carried out on the opposite side of the machine, it is first of all necessary for the operative members to be returned to the aforesaid bottom position. The heart-shaped member 94 therefore forces the right swing 4head and the falling bar '90 upward by ymeans of its concentric tracks 107 and 108 lwhich act. on the rollers 88a and 92a of the push bars 88 and 92. The anchor 7 and its rollers 10 and 11 (Fig. 4) now again take up the middle position, the anchor 7 being .therefore vertical and the box 13 horizontal (Fig. 11c` dotted lines), while the-two swing` heads and `the falling bar take up their highestl position. `The sinker cam 26 and lever 27 now occupy the position shown in Fig. 6. Consequently, after a total rotation through 180, the bottom position is again reached, but `with the difference that the sinker cam 26. the sinker lever 27, the thread guide 131 and the slurcocks 150 and 151 are now on the opposite side. After being in this second bottom position, the anchor 7 moves toward the left (Fig. 11g), and the working operation already described is repeated on the other (left-hand) needle bar (60), thus completing a row of meshes in tubular ware. After the shafts 2 and 3 have turned through another 180, the original bottom position is reached once more,

` l and the series of operations already outlined is repeated in the described manner.

2. One-side plain gorizia-To make .goods on one and the same needle bar (59 or 60) throughout, the rollers 10 and 11 of the anchor 7 (Fig. 4) are pushed along their pivots, thus throwing out of action the change shaft 6 (Figs. 4 to 6) and the heart-shaped member 94 mounted on same. lffthese rollers I0 and 11 be pushed toward theright, the needle bar ,59 is brought into actlon.

The anchor 7 remains in the position facing v` the shaft and the box 13 rests on thesloping surface 16 of thetrestle frame 18 (Flg.

y 11). If, on the-other hand, the rollers 10,

l1 are pushed toward the left, the needle bar 60 comes into operation. which of the two needle bars is. to be used bar pusher when the heart-shaped member is stationary, so that the rollers on the falling-bar pusher are able to move away freely.

3. Ribbed goods (reversible goods).- When the formation of meshes is to proceed on both rows of needles at the same time, the swing heads remain in one position all the time, that is to say, the loops are made on the same row of needles all the time, as in the case of one-side (plain) goods, while 'the working out of the formed loops is effected by both needle rows in the manner known in connection with rib machines. Of course, it is also possible to al- 'lQw the two rows of sinkers to come into The choice of v .is therefore open. In this class of work in ber 94, and on the other to the-.action of the lifting surface 87, on which latter they bear by means of their set screws. Only the curves 107, 108,95and 96 ofthe heartshaped member act on the rollers (arranged near the lower endsV of said bars.) The curved parts 95 and 96v are movable on and bear against-the heart-shaped member 94 and form a continuation of the outer curved tracks of said member. If one of the rollers o f the falling bar pushers is in lposition within that portion of the heantshaped member which .lies between' thesaixl curved parts 95 and 96, for example the roller of the bar 88 (Fig. 11x) it would strike against the curved part 96 during the ascent of the bar 88 and be prevented from rising further. This is avoided by the said member 96 turning on its pivot, and itself continuing to move upwardly with the bar 88.

4. T ick-ling (lnawowz'nf/i-Fig 12 illustrates the device for tickling, in which the cams concerned are thrown in and out of gear by the displacement (which will be described later on) of the shaft carrying same, as that there comes into position under the cam lever anotherl cam corresponding to the narrowing period. As long as narrowing is not in progress, the two- arm levers 125 and 126 of the parallel shafts 123 and 124, come in contact with a socalled blind cam 129, so that the tickling devices 119 and 120, which are articulated to the levers 125 and 126, remain at rest (Fig. 12). If, however, in place of the blind (circular) cam 129,

the tickler cams 127 and 128 are pushed under the lever rollers 125% 126a then the tickling device comes into operation. If the box 13 with the swing heads be in the left position, then the tickler device 119 is operated by the cam 127 arranged on the shaft 2;-

whereas, if the box 13 be in the right hand position, the other tickler device 120 comes into action. The presser cam 66 (Fig. 10) is replaced, during the tickling process, b v a blind (circular) cam, represented b v dotted lines. The needle-bar cams 53 and 54 (Fig. 8) are replaced by cams 138 and 139, shaped in accordance with the narrowing period and a cam 103 (Fig. 9) corresponding to the narrowing period is used in placeof the sinker cam 85. The roller standard 46 (Fig. 7) is drawn by means of a spring 167 against a chain 162 having links 162a of a varying height, which runs over a chain wheel 163.- This chain is periodically advanced, inasmuch as an operating lever 165 with pawl 166 is induced by suitable means, such for instance as a cam or cam shaft, to more a ratchet wheel 164 forward one tooth at a time. If now the shafts 2 and 3 are to be displaced, the roller standard 46 is moved, as allow d by the chain 164, toward the shaft 2. so that the rollers 47 and 48 are able to take up another position in relation to the stepped cams 42 and 43. This displacement of the shafts takes place when the surfaces 44 and 45 (Figs. 7a and 7b) of the shaft pusher cams 42 and 43 come into position in the direction of the vertical central line (Fig. 7). On the roller carrier`46 being turned in the direction of the shaft 2, this carrier imparts a slight turning movement to the shaft 40, 'inasmuch as it moves a lever 49,- mounted on same, by means of a stud 49. By this means a roller 50 on an arm 50 (Fig. 6a), mounted on the shaft 40, is brought into reach of the' noses 38, 39

(Figs. 2, 6a and 6") arranged on the coupling member 35. As soon as one of these noses comes into sliding contact with the roller 50 the coupling member 35, and the shaft 2 firmly secured to same, undergo displacement, so that the coupling members 34 and 35 are disengaged and the sinker cam 26 and sinker'lever 27 are thrown out of action. The narrowing begins when the sinking of the loops toward the right has been effected after the box 1 has deposited itself on the sloping surface 16 of the trestle frame (Fig. 11). The tickler lever 126 is now lifted by the tickler cam 128 (Figs. 1 and 12),

` and the tickling device 120 is brought into ilposition for narrowing. After the narrow'- ing-whichy is well known and therefore needgnot be more fully described here#is completed, thestickler device 120 retreats, and the box lttufns on to the side 17 of the ,x frame"so"that` he other side of the machine is operated. The roller standard 46, which pivots onthe axis 12, then swings back and in consequence of the opening of the flap of the heart-shaped member 94, the roller 47 attains its top position, whereupon regular knitting is resumed.

5. The narrowing operation in one-side working-for instance in making a heelis carried on in the following manner Theroller standard 46 (Fig. 7) is operated by the aforesaid chain 162 and its roller 47 is brought into engagement with the salient peripheral portion of the shaft-pusher cam 42; and at the same time the roller 48 of the shaft pusher cam 43. ascends into the top position. The cam shafts 2 and 3 are thereby pushed toward the left in such a way that, in place of the ordinary cams,

those lying adjacent thereto come into po-V sition under all the levers. These new cams are of such shape that they combine the two operations of loop forming and narrowing into one. The machine then works by forming the loops from right to left, followed by narrowing, and then forming loops from left to right, and so on. As the roller standard 46 moves over still farther toward the right, the arm-49 is drawn downward still lower, and the arm 50 (Fig. 6a) connected to the shaft 40, bears closely against the coupling member 35, so that the sloping surface 39 (Figs. 6a, 6") does not come into operation. The sinker lever 27 and the sinker cam 26 are thrown out of action after each semi-revolution. The boX 13 remains continuously on the sloping surface 16 of the trestle frame 18. During this one-side narrowed knitting, the cam holds the ticklerA uit' responding manner when working on the other side of the machine.

That I claim then isz- 1. In a knitting machine, the combination -with two rows of needles and loop sinkingboth rows simultaneously.

2. In a knitting machine having two needles rows, loop sinking devices for said needle rows, and a frame rotatable about a pivot and carrying s aid sinking devices whereby the latter may be changed in posi tion in relation to the needle rows for the purpose described. V

3.
