it is an object of my invention to, provide an improved ,sinker for a machine of the kind described for knitting loop-plush fabric. To this end, I arrange the usual set of needles, and sinker allotted to each needle with a nib directed toward the front side of the allotted, eedle, i. e., that addition to the plush throat, a web-holding edge or step is formed in the upper, edge of the nib .which is at a higher level than the, plush throat. In order toprevent interference with the free 5 movement offtheplush loop of! the point of nib, the section of the nib is so determined by suitable arrangement of the upper and lower edges of r the nib that it is a maximumat the rear end side of the needle where the latchls provided, and or root of the nib, as will be described. I arrange a plush throat at the rear e d of the It is still another objectoi my invention to pronib, and a point at the front end oithe nib which vide a sinker for. knitting certain portions of the fabric more closely or more loosely than others.

. To this end, I provide a web-holding edge on the sinker which may have a depression, d arrange the ground-threadlthroatfat a higher or lower level thanthe web-holding edge, in conformity with the required closeness of knitting.

It is still another object of my invention to provide an improved knitting, machine for operat- 2o ing the sinkers according to my invention. To this end, I provide a lock with an upper and a lower cam for cooperationwith the butts of the sinkers, ,and means for active position withrespect to the sinkers. The individual-sinkers are equipped with butts for cooperation with one or the other cam, so that my machine requires two kinds of sinkers, one

level than the plush throat. A throat is positioned substan- .tiaily vertically below the plush throat. The ground-thread throat need not be in exactly vertical position below the plush throat but is preferably arranged ahead of theplush throat. In a sinker oi this type, the lower end of the throat for the plush thread is ata lower level than the point of the nib which in turn is positioned at a higher level than the throat for the ground thread, and this arrangement, renders for separating the plush and ground threads when the sinker ground-thread above its lower end is verticaior substantially vertical and preferably inclinedto the rear,and

serves for reliably placing the plush thread at a for cooperation withthe upper, and one for colower level than the point of the nib. operation with the lower cam.

Figs. '18 to 21 are diagrams illustrating sinkers of the kind shown in Figs. 1, 2 and 3, equipped with means for obtaining fabrics of various de-i grees of closeness. I

Referring now to the drawings, and first to Figs. 1, 2 and 3, the machine is equipped with a lock having two cams for cooperation with its knocking-over sinkers, as will be described, and therefore it requires sinkers of two kinds for cooperation with the individual cams of the lock. s are the sinkers forcooperation with the lower, and s" are the sinkers for cooperation with the upper cam.

Referring now to Figs. 2 and 3, both kinds of sinkers, s and s", are notched at i8 for the reception of a cam ring, as will alsobe described. The rear ends 31 of both kinds are vertical, and in the sinkers s, for cooperation with the lower cam of the lock, the lower edge of the butt33 is flush with the lower edge of the sinker,-while in the sinkers s, for cooperation with the upper cam, the butt 34 is placed at'a higher level.

The beaks of both kinds of sinkers are similar and will now be described with reference to Fig. 1 for a sinker s which may be designed for cooperation with the lower or upper cam of the lock at its rear end. 2 is a nib above the notch 3 at whose rear end is the ground-thread or castingofi throat 9, and whose lower edge is the web- 'I'he pointed end 5 of the nib 2 is at a higher level than the lower end 4 of the plush throat 1 for the plush-loop thread 21. The upper edge 6 of the nib 2 extends in downward direction from the point 5 toward the lower end 4 of the plush throat 1 in an unbroken curve but may be stepped as will be'described with reference to Figure 4. The gradient of the edge 6 toward the end 4 facilitates the introduction of the plush thread 27 from above. However, the plush throat may be inclined in forward direction, as will also be described with reference to Fig. 4. The lower edge 8 of the nib 2 is an unbroken curve, like its upper edge 6,-and extends from the point 5 of the nib 2 down to the upper end 8 of the groundthread throat 9 where the ground thread 28 is placed. The ground-thread throat 9 is positioned substantially vertically below the lower end 4 of the plush throat I. Substantially vertically means that the ground-thread throat need not be exactly vertically below the lower end 4 of the plush throat, and preferably it is slightly ahead thereof, as shown.

A modified sinker will now reference to Fig. 4. is arranged above the notch 3 as described but its upper and

lower edges

5 and 8 arenot unbroken curves, as shown in Figs. 1 to 3, but the upper edge 8 has a substantially horizontal step end 4 of the plush throat be described with and a-gradient 55 connecting the horizontal portion 55 to the lower end 4. The plush throat 55 forward direction and the upper end of the ground-thread throat 9 is arranged at a by the upper cam 5|.

' ject, respectively, The nib 2, with its point 5,

considerable distancei'orwardly of the lower end 4 of the plush throat 55. The lower edge 801' the nib has a gradient which is substantially parallel to the gradient 55 of the upper edge. The two stages at 55 and at 4 permit the sinking of plush loops of various lengths. The condition which is to be fulfilled in order that no tension is exerted on a loop which has been sunk at the lowest point 4 of the upper edge 6, when it slides on the step 55 which is at a higher level than the point 4, is that the cross-sections of the nib should decrease from 4 toward its point 5, or, in

other words, that the cross-section at the root the distance a between the

throats

4 and 8 must be equal to the vertical distance b of throat 4 from the web-holding edge of notch 3.

Fig. 5 shows a complete sinker of the type illustrated-in Fig. 4, for cooperation with the lower cam of the look. A sinker for the upper cam has not been illustrated, it being understood that the only distinction of this sinker is the position of its butt at 34.

Referring now to'Figs. 6 to 9, these illustrate a portion of a circular knitting machine, only those parts having been illustrated, which must be shown in order to enable a person skilled in the art to understand my invention. Thus, the sinker camming portions, such for engaging in the slots 3! of the sinkers.

25 and 5| are, respectively, the lower and upper cams, already referred to, of the lock. In the present instance, only sinkers s forcooperation with the lower cam 25 have been shown in the machine, and so the upper cam 5| is idle and only the sinkers s, with their butts 33, are operated by the lower cam 25 for forming plush loops as will be described. Similarly, only sinkers s might be inserted and their butts 34 be operated As a rule, sinkers s and s" the'upper cam 5|, into active position. Both kinds'of sinkers, s and s", may also be operated at the same time by a third cam, not shown, if required for a given pattern.

The cam 25 has camming portions, such as 25 and 25 for engaging the butts 33 of the sinkers Both cams are mounted in suitable guides, notshown, and placed one upon the other for free relative displacement.

cams

25 and 5| at. opposite sides thereof. A slide 53, with a pairof camming faces I53 and I54 at its upper end, is mounted to slide in the frame of the machine for cooperation with the lug 5| of cam SI, and a similar slide 52, with a single camming face at its upper end, is mounted for cooperation with the lug 25 of cam 25. Two springs I55 are provided for pulling the lug 5! of cam 5| against its slide 53, and similar springs I 56 are provided for pulling the lug 25 of cam and 12, Fig. 11 showing only 25 against the slide 52. The free ends of the springs are attached to a suitable bracket I51.

Any suitable'means may beused foroperating the

slides

52 and 53. In theexample illustrated, fork-shaped rocking levers I58 fulcrurned at I59 areprovided for this purpose, and. operated by connecting rods I60 from any suitable mechanism, not shown. The free endsof the rocking levers I58 bear against the

lower endsof theslides

52 and 53, and springs I5I are attached to arms. I52 on the slides atone end, and to the bearings I59 of levers I58 at the other end. In the position illustrated in Figs. 6 and8, the slide 52 hasbeen raised by its lever I58, and its cam face has pushed the lower cam25 inwardly for cooperation with sinkers s. 1 I

Certain sinkers and needles have been selected for describing their cooperation with each other and with the lower cam. 25 which has been moved into active position by slide 52, and these sinkers and needles have been marked with reference numerals, as indicatedat the. left in Fig. 6. The section line VIII-.-VIII in Fig. 6 extends through the sinker s (3IJ3) which is between the needles n(II) and n(I2 As the needles and sinkers rotate about the axis a: in the direction of arrow A, while the cam 25 and the cam ring H are stationary, the sinker s (303) is just going to run off the camming portion 25 --25 of cam 25 at the end 25 and torun, onto the subsequent camming portion. The camming ring 311, does not influence the sinker s (3Il3) as itswidth at the camrning portion 3I'I is less than the width of the slot I8 in the sinker.

Referring to Fig. '7. theneedleni3ll9) which is the first one inthe direction of arrowA, is in its The subsequent needles are lowered into their lowermost positions, 11.( I4) and n(I5), and then raised again, beginning with 11(I5 The plush-loop thread 21- and the ground thread 28 which issue from the

thre fi uides

29 and 30, respectively, are so .far apartat the point where the sinker-s (,2) is positioned, thatthe point 5 at the end of its nib 2 entersbetweenthethreads, as shown in Fig. 10. The nib which is directed toward the front or latch side of the needle,and in the position illustrated in Fig. 10 has moved beyond the back of the needle with its point 5, holds the plush-loop thread hook of needle n(IIl), separate from the ground thread 28 which is in the ground-thread throat 3.

The needle descends while the sinker s (2) moves toward the left, as indicated by the arrow B. The plush-loop thread 21 isguided toward the lower end 4 of the plush throat I by the upper edge 6 of the nib .2.

An intermediate position is shown in Figs. 11

of the sinker s (4) and the needle n(I2), drawn to a larger scale than Fig. 12. Here, the plush-,- loop thread 21 is at the lowerend 4 of the plush throat .I, and the ground thread 28 is at theupper end 8 ofthe ground-thread throat 9. The latch of the needle has been closed and the back i of the needle shank engagesthe groundthread 28 in the throat 8. Fig. 12 shows the same operation. The needle still descends and the sinker still movesin the direction of arrow B,toward the left. a 1 Figs. 13 and 14 show the sinking operation," in a manner similar to the showing of Figs. ll and I 12, for theneedlen(l4) and the sinker 8 (6).

This configuration prevents the plush loop 56 from sliding upwards on the edge, and becoming slack.

The ground thread 28 is caught between the shank of the needle n and the throat 9, as best seen in Figs. 11 and 13, so that the ground thread 28. is locked against horizontal movement, like in its throat 4, and, in

the sinking position, Fig. 13, the ground thread 28 is in front of the plush-loop thread 21. It does not move from this position until the sinking movement has been finished, and consequently also during the subsequent casting-off movement. With a sinkeraccording to my invention, the plating of plush goods is effected under absolutelyreliable conditions, and this was impracticable. heretofore, because the ground thread 28 had a certain freedom of movement in the space between the shank and the latch of the needle so that frequently the ground thread 28 swings in horizontal. direction,and. before sinking, is placed at the rear of the, already sunk, plushloop thread 21, instead of being in front of such thread.

cause the sinker moves in direction D. The loop becomes slackerand slacker while ascending the edge of the nib, and finally slides off, the nib 5 unobstructed, when the sinker has moved far enough to the rear. In Fig. 1'7, the point 5 of the nib is just about to be extracted from the loop 55.

If the ground-thread throat 9 is at 9a, as shown in dotted linesin Fig. 4, and the distances a and b are equal, as described, a being the length of the plush loop 55, the tension of the loop 56 is equal to the tension of the ground thread.

If the upper edge 6 is stepped. as also shown in Fig. 4, in order to obtain plush loops 56 of various art) the vertical crosssection of the nib 2 at the lowermost step 4 must be the largest cross-section of the nib,

along the upper edge 6 of nib 2 and the step 55 It will appear from Fig. 4 that the vertical sec to 5 are such that the 8 decreases from 4 to 5.

I A plush-loop throat 55 which is inclined in forward direction, as shown may be preferable to the rearwardly inclined throat I, as by it the thread is positively placed below the nib, the operation of casting-off is performed reliably, and

the plated goods obtained areof good quality.

Sinkersaccording to my invention may be de signed forivarying the closeness of the fabric which is knitted on a circular machine.

It is in circular knitting machines of the usual type, it is imknown I that equipped with sinkers 1 possible to knit a given portion of a course .of

loops more closely or more loosely than its other portion. This drawback is particularly difficult if it is desired to knit certain courses with,.and other courses without, plush loops. For instance,,assume that in a two-threaded fabric the second thread is knitted into plush loops for splicing certain. portions of the fabric, for instance, the sole of a stocking, without knitting an extra splicing thread into this portion, the plush-looped portion of the fabric becomes stronger but at the same ime the structure of its ground-thread loops becomes more loose than in. a two-threaded plain'fabric, without plushloops, and the plush becomes too thin. Therefore, in order to impart to the fabric, and particularly to its plush-looped portion, the required strength, the machine must be adjusted for closer knitting, but this involves the drawback that, if the ground-thread structure of the plush-looped portion is close enough, the'portIonwithout plush loops becomes too close. If a thinner thread is used for the plush-looped portion than for the plain portion without the plush loops, the plush-looped portion must be knitted more closely still than would be required if, as

' assumed above, the threads for both portions are of equal thickness. In such cases, the drawbacks of existing circular knitting machines are particularly apparent.

Conversely, it may occur that a single thread, or several threads, are used for the plush loops which thread, or threads, is so thick that the ground fabric in the plush-looped portion must be knitted more loosely than the plain portion without the plush loops, in order that the splicing by the plush loops does not become too hard, and the too taut knitting does not cause undesirable consequences during the formation of the loops. This operation is also impracticable in existing circular knitting machines, and particularly, it cannot be performed if only a portion of the courses is tobe knitted with plush loops.

It is another object of my invention to eliminate the aforesaid drawbacks. The problem is, in fabrics knitted on circular knitting machines, to knit more closely or more loosely, as may be required, the ground fabric of the portion which has plush loops, than the plain portion without the plush loops, in such manner that the length of the plush loops is the same for the more closely and for the more loosely knitted ground fabric of the plush-looped portion. .I solve this problem by sinking the loops of the ground fabrlc for the plush-looped portion shorter than for the plain fabric, if the structure of the ground fabric for the plush-looped portion is to be closer than for the plain portion without the plush loops; and by sinking the loops of the ground fabric for the plush-looped portion longer than for the plain fabric, if the structure of the ground fabric for the plush-looped portion is to be looser than for the plain portion without the plush loops.

In order to obtain uniform length of the plush loops in both cases, the position of the plushloop throat I is the same as to its'level with respect to the needles, while the position of the ground-thread throat 8* plush-loop throat I is varied as required for closer or looser knitting of the plush-looped portion than the plain portion without the plush loops, the ground-thread throat being positioned at a higher level for longer, and at a lower level for shorter, ground-thread loops in the plush h ned P rtion with respect to the- I suggest to solve this problem by providing sinkers in which the web-holding edge for the ground thread is arranged at two distinct levels, the front portion being arranged at the normal level with respect to the hooks of the needles ,for sinking normal plain fabric, at normal closeness, while below the plush throat I where the plush loops are sunk, the web-holding edge is arranged at a level above or below its front poroperation with the upper cam 5| as well, serves for knitting the ground fabric more loosely for the plush-looped portions than for the plain portions, and therefore its ground-thread throat I64 is arranged at a, higher level than the front portion I65 of the web-holding edge.

It is known that for knitting fabric with plush loops the sinkers are advanced earlier and for a longer distance with respect to the needles 1!. than for knitting plain fabric. Fig. 18 shows the position of the sinker in which plush loops are knitted. In this position, the point where the ground thread 28 is sunk by the needle n, is just below the plush throat 4. At this point, the web-holding edge is raised to form the ground-thread throat I64 at a higher level than the front portion I65. 7

Fig. 19 shows the position of the sinker for knitting plain fabric, without plush loops. For this operation'the sinker remains in its initial position, and-the point where the needle 12 sinks the ground thread, is now on the web-holding edge, at some distance to the rear from its front portion I65, where a depression or step is provided at I66. The loops of the ground thread 28 are longer in Fig. 18 than in Fig. 19.

Figs. 20 and 21 show the same positions of the sinker as in Figs. 18 and 19, but for knitting a fabric whose ground fabric is knitted more closely in the portions having plush loops, than in the plain portions. In this sinker, the ground-thread throat I61 is arranged at a lower level than the front portion I65 of the web-holding edge. The loops of the ground thread 28 are shorter in Fig. 20 than in Fig. 21.

It is not necessary to adjust the machine for closer or looser knitting while knitting a course, all that is required being to use sinkers with a high-level ground-thread throat I64 for a loose ground fabric in the plush-looped portions, and.

with the ground-thread throat I64 or I61 at a lower or higher level than the -of the web-holding edge.
