PATENT OFFICE.

As is well known, the stitches of a knitted fabric are interlinked in such a way that each stitch 3, Fig. 8, is encompassed and held by such a 2 of the previous row. Without this encompassing one would only get loose loops 1, 4, 1, which open up immediately; therefore the first row of loops 1,1 must be held by a row of stops a _z b _% , usually made by hand. Attempts have been made to do this "beating", ie wrapping thread around the individual needles, for smooth goods with mechanical devices, but even then it has not been completely satisfactory, and for marginal or right-hand and right-hand goods, namely on Hitherto it has not been possible at all to attach round-edged chairs, so the so-called patentränderwaare, i.e. the arbitrarily many-needle edging ware (Fig. 8 shows four right-hand stitches in I, four left-stitches in II), has not been able to be used as stocking lengths, because they have none had a solid starting edge and a double edge in it cannot be sewn or worked on.

The present apparatus now works show the fixed stop edge, such as a _s b _like in Fig. 8 and 9 for each legal and Rechtswaare.

In Fig. 9, it is assumed, that in the circular edges chair four needles chair α with four machine needles b alternated, so the four and Vierränderwaare, Fig. 8, is produced, in which four right meshes with four I purl stitches alternated II. The hitting is now done in various ways, for. B. so that the thread wraps each chair and machine needle α and b once (a ₃ and b _z ), and this is done by a thread guide 0 (Fig. 9, right) with the following movements:

After the last loop made, a ₃ ο stops behind the needles, but the chair is turned by one needle to the left by the stop device, so that 0 appears to go to O ₁ ; then the guide moves one needle to the right, i.e. to O ₂ , then swings forward to O ₈ , moves again one needle to O ₄ to the left and swings back to O ₁ , with the next needle a - has been wrapped and the same process is repeated.

The round-edged chair is drawn in FIGS. 1 and 3. The needle cylinder c with the chair needles α is turned over by C ₁ e from ff _x when f is engaged with e, and it takes the machine d with the machine needles b either by needle engagement or by special gear transmission 17, 18 in a known manner . The needles α and b are moved up and down, as well as back and forth, in an equally known manner by locks 19, 20.

The transmission shaft g , Fig. 3, which is used to operate several round chairs standing next to each other on the frame n> , drives the shaft f _x through g ₂ f ₂ and the chair with fe , and the shaft through ß ₂ h Zz ₂ z ₂ i and finally the shaft k of the stop device by means of a cord drive from Z ₁ to k _i. The latter is attached to the frame 6; he holds the stop thread guide o in the lever Wi ₁ m , which is opened by the lever Z ₂ I ₁ I from the eccentric

k is moved back and forth, as well as up and down, so that it gets into positions ο and O ₄ . Furthermore, as FIG. 2 shows, m WJ _{1 is} displaceable on its pivot pin and is pulled back and forth on k _{by i 2} ij t and the cam plate , so that 0 also has a path in the direction of the needles (FIG. 9, O ₁ to O ₂ or O ₃ to O ₄ ).

During this stroke, the ordinary chair operation is disengaged by fe, Fig. 3, i.e. H. been ff ₃ ρ by levers JJ ₁ subtracted from e, and the chair is only continued rotated by an eccentric DAF on k _n% n by lever _{K4. 2,} the rod M ₁ shifts which η the fastened on e wheel and thus the The chair continues to rotate as required.

The apparatus can also be set up in the manner shown in FIGS.

The leader 0 sits here on the rail m, which is moved by the lever I ₃ L ₂ I ₁ and eccentric / on k in the direction 0 O ₄ and back, and the entire support frame ν is rotatable about the pin 7 in the storage frame 6 and becomes rotated only a little by means of the arm V ₁ and the cam V ₂ , so that the guide 0 receives the lateral movement.

An ordinary counting chain \, Fig. 7, determines the length of a piece of goods,. thus states after how many rows a stop edge should be made by then moving the chair out. This chain \ lies on the wheel ^ ₁ , which is rotated by the ratchet wheel χ through JC ₁ , 10, 9, 8, in that a lever y _x y, Fig. 3, receives the appropriate movement from a pin q of the drive wheel e. If an increase ^ _{2 of} the chain \ comes under the end s _s , Fig. 7, of the release lever s _i s ₃ s, the same is lowered at s with its cross bar S ₁ S ₂ , Fig. 7, 3 and! . Until then he has held the lever ρ at 11 to the left with S ₁ , Fig. 1 and 3, if it sinks, the spring 13, Fig. 3, pulls ρ with f to the right and moves the chair out. The worker now has to push the lever r, FIGS. 1 and 3, which was previously on the right in r ₃ , FIG. 1, to the left and thus engage the wheel h ₂ in z _2; the cross bar S ₂ rising again then holds r, as in 'Fig. 1 shows, engaged, and the stop device is now put into operation by i I ₁ k _{1 k.} Of course, the same works only during one rotation of the chair, and it rotates the chair itself in the manner described above as required; during this rotation, the chair's systems continue to work undisturbed. After this rotation there is again an increase ^ ₂ , Fig. 7, under S ₅ and again lowers the front lever s with S ₁ S ₂ , whereby the spring 14, Fig. 3, immediately moves the lever r with / 2j A ₂ to the right pulls, so disengages the apparatus again. The worker now has to return to the usual chair operation with Pp ₁ , which continues to work the goods on the just completed stop edge.

If, as in Fig. 9, several machine needles b, without having chair needles α between them, follow one another, then one must insert wire pins, ie needles without hooks, into the chair at the points α _{λ, because otherwise when hitting them through} the forward movement of the guide (0 O ₄ in Fig. 1 and o ₂ O ₃ in Fig. 9) ■ the loops on b are pulled forward over the tongues; But of course they have to lie behind the tongues, since they are supposed to represent old stitches.

The counting apparatus X ^ ₁ , Fig. 3, can also be used for other things, for example by lever 16, for pulling down a lock eccentric 19, Fig. 1, for the purpose of forming long rows.

Claims (1)

Patent claim: A round-edged chair, which produces a stop edge on any number of needled peripheral goods (1 and 1 or 6 and 3 or 2 and 4 etc.) in such a way that its drive shaft (g), when the ordinary chair drive (fe) is disengaged, an auxiliary thread guide (o ) radially (o ₂ O ₃ and O ₄ O ₁ , Fig. 9) up and down (o O ₄ , Fig. 1 and 4) and tangentially against the needle roller and cage assemblies (O ₁ O ₂ and O ₃ O ₄ , Fig. 9 ) moves, as well as this chair itself is given rotation (by k K ₄ n ₂ W ₁ η e), during which rotation the usual loop formation in the individual systems of the chair is continued.
