In the double latch needle knitting machine of the main patent 95683, the lifting of the auxiliary needles c resting on the tappers b to release the double latch needles is effected by needle rails ^ ^ ¹ on which the heads c ^{3 of} the auxiliary needles run up. According to the additional patent 98020, the lifting of the auxiliary needles is brought about in a different manner in that the auxiliary needle is raised to an enlarged extent by the needle bar ^ ⁴ , which engages in an inclined slot / the auxiliary needle formed by a wedge tip. In the additional patent 114874 it is also indicated that rails % ^x , connected to the carriage, can bring about the lifting of the auxiliary needles. In all of these embodiments, the parts for lifting the auxiliary needles c, which are still advancing, lie between lock needles and double latch needles, i.e. facing towards the knitting comb, and thus block those points of the knitting machine in which the knitting is taking place and thereby make it difficult to see the knitting process.

On the basis of the present invention, the lifting of the needle tips c ^{s of} the auxiliary needle and their lifting out of the head a 'of the double latch needle α is brought about by the fact that the auxiliary needle c, which swings in a known manner by means of its pin 1 in a groove 2, 3 of the pusher, bezw at their tail end with a wedge approach. Outlet 4 is provided, which abuts against a fixed abutment surface 5 attached to the castle or to the knitting machine bed. The invention is shown in the drawing, namely Fig. Ι shows the Grundrifs the Schlofseinrichtung a knitting machine of the present invention with the associated needles, Fig. 2, 3, 4 and 5 show in longitudinal section successive positions of the pusher, auxiliary needle and Double latch needle and the lifting of the auxiliary needle to lift out the head a ^{1 of} the double latch needle a.

The device is as follows: The double latch needle α is guided with its heads a ¹ between the pusher b in the needle channels, so that it cannot perform a free longitudinal movement in the same in the sense of the main patent 95683. The auxiliary needle c is swingable by means of its pin 1 on the pusher b and accordingly beveled on its lower edges on both sides of the pin 1, it is held in the hook α ^{l of} the double latch needle by suitable fixed cover rails or cover plates 6 of known type that can be moved with the lock α held (Fig. 2) until BEZW due to the action of the needle lifter. the

Needle lifter edge m the pusher b has pushed the double latch needle α far enough to the center of the bed. If the auxiliary needle c with its foot 7 and thereby the pusher b is pushed further forward through the needle lifter edge r of the lock, the outwardly lying lower edge of the abutment 5 presses the sloping surface rising towards the rear, respectively. Outlet 4 of the auxiliary needle c downwards, so the auxiliary needle tilts around pin 1 in the comb 2, 3 of the pusher b, and the hook c ^{3 of} the auxiliary needle lifts out of the hook α ^{τ of} the double latch needle (see Fig. 3). This lifting of the hook c ³ from the hook a ^{1 of} the double latch needle α takes place while the auxiliary needle and the pusher are advancing.

Are the auxiliary needles of the pusher through the foot 7 pretty much at the end of their feed, the inclined surface has BEZW. Outlet 4 at the tail end of the auxiliary needle passes the abutment surface 5 and the bevel 8 of the auxiliary needle has emerged from under the cover plate or cover rail in such a way that the hook c ^{3 of} the auxiliary needle c is completely lifted out of the head α ^{x of} the double latch needle α (Fig. 4).

By the action of the other side of the bed, not shown in the drawing, the double latch needle α is pulled over into the other bed in a known manner. The auxiliary needle c is withdrawn again by the countersink f , the inclined surface BEZW. Outlet 4 slides along the abutment ^{edge 5, the hook c 3 of} the auxiliary needle c is thus lowered again, the cover plate 6 lies under the part 9, auxiliary needle c again lies on the pusher b.

In this case, the abutment edge 5 can be very advantageously connected to the triangle of the castle. It lies outside the functions of the auxiliary needle heads c ^s and the double latch needle heads as well as the double latch needles a, and therefore allows the needles to work freely and to easily overlook the knitted fabric and the needles.

If the abutment edge 5 is worn, it can be easily replaced or readjusted. The lifting of the auxiliary needle c on the basis of the present invention is the opposite of the lifting in the previously known left and left knitting machines, in which the latter is done by lifting the needle either on the head c ³ or near the head, i.e. at the front end of the Auxiliary needle, was brought about.

Claims (1)

Patent claim: Double needle knitting machine of the type protected by patent 95683, characterized in that the auxiliary needle (c) is lifted out of the head (a ¹ J of the double latch needle (a) during the advance of the auxiliary needle and the pusher by a fixed, with the bed or abutment (5) connected to the lock takes place, which rests against a sloping surface that rises towards the rear or an outlet (4) at the rear end of the auxiliary needle swinging on the pusher (b) , thereby depressing the rear end and the auxiliary needle hook (c ³ J lifts up. 1 sheet of drawings.
