- edge acting as a needle latch opener and capable of acting also as a needle closer if certain kinds of needles are used.

An embodiment of the machine is illus-.

' trated in the accompanying drawings.

Fig. 1 is across section of the essential parts of a machine equipped with latch needles.

Fig. 2 is a partial front view looking from the right hand side of Figure 1.

Fig. 3 is a partial plan, looking in the direction of the arrow III in Figure 1, some parts being removed.

Fig. 4 is a partial view showing the work holder with the work attached thereto.

Fig. 5 is a front-view showing the holder and work looking from the right hand side of Figure 4. Figs. 6 and 7 are, respectively, a side view and a rear View of a modification.

Figs. 8 and 9 are detail views illustrating the operation of the present invention when used in conjunction with latch needles.

The needle bed 1 supported by the frame 2 is provided with a portion 3 extending outwardly in the direction of the needles 4 and wherein the needles are guided during their reciprocatory movement actuated by usual cams on a slide 6. In the usual knitting machines the outer end of the needles is rounded. According to the present invention the needles are provided with sharp points because the ends of these needles are intended to be passed through the work during the mending operation of the machine. At the outer end of the needle bed there are arranged usual, fingers 8 (so-called platines or releasing combs) and transversely above these fingers 8 there is arranged an upwardly yielding latch opener 9 which is pivotally connected at 13 to the needle bed extension 3.

, arranged beneath the needle bed and ten ing to hold the latch opener in the lowermost position. The strength of the spring may be adjusted by means of a screw 17 I The latch opener 9 is preferably arranged.

in an inclined position in order to enable the needles to pass by more easily during their backward inward movement.

On the needle bed 1 there is arranged a hollow work holder 20 for the work 21. This holder is pivoted on pins 22 and 23 on the needle bed and be swung transversely against the pressure of a spring 24. The work 21, in which a hole 27 is to be mended, is stretched on the holder (Figs. 45) in such a manner that said hole is located as a wall closing the outer end of the hollow part of the holder between its side walls 28 (see Figure 5). The work, for instance a stocking, is fastened to the holder preferably by means of an endless spring 30 or by other elastic means such as a rubber band, which is pulled over the work around the root of the work holder. During the working operation the work holder is loaded by weights so as to turn step by step on the pivots 22, 23 in a manner similar to that used in knitting machines.

The holder 20 may be provided at its inner end with lateral projections 29 upon which the free portions of the work can rest.

On the slide 6 which may be moved transversely to the bed 1 is mounted an overhanging arm 35 carrying in substantially right angle relation thereto an extension 36, the end of which may be given the form of a. flat plate 36, which at the reciprocating transverse movement of the slide 6 is moved in front of the opening in the holder 20 covered by the work. This plate is provided at its thrown outwards by the needles.

lower part with a longish opening 37 through which the needles 4 may project during their working operation. -As the work is located between said plate 36 and the holder 20 the plate 36 will prevent the work from being Said opening 37 is limited upwards by a rib 39, the lower side of which is provided with a sharp edge adapted to effect the opening of the latches 4 if they should not have been opened already by the latch opener 9 proper. Said rib 39 and edge 40 may also provide for a pressing action on the needle hooks when the needles are withdrawn as shown in Fig. 8. On the plate 36 in front 0f the rib 39 there is arranged a bar or bow 42 adapted to prevent the latches 4 from being thrown unintentionally forwards into a closing position at a wrong time, viz: before the thread has been placed into the needles. This bar 42 may also be placed on the thread-carrier 44 and may consist of a flat, longish strip 42 as shown in Figs. 6 and 7, which indicate a side view and a rear view respectively of the thread carrier with the strip 42 fastened to it.

In order that the operation of the element 42 ma be more clearly understood, reference is ma e to Figs. 8 and 9 showing the position of the needles at two difl erent times during their movement and also the relation of their latches to the element 42. Fig. 8 shows the needle in its outermost position ready to receive the thread, and Fig. 9 shows the needle after it has been retracted somewhat into the needle bed.

As the needle moves forward the latch 4 is opened by the latch opener 9. During the passage of the thus opened needle through the slot 37, the plate 45 is engaged and slightly raised, the plate 45 yielding upwardly and outwardly to permit the passage of the opened needle beneath it. The needle then continues to its outermost position shown in Fig. 8. At the moment that the needle stops, the latch 4 because of its inertia, has a. tendency to tilt upward and would close the needle were it not prevented from doing so by striking against the bar 42. The same effect should be achieved if the bar 42 were replaced by a fiat, longish strip 42' mounted on the thread carrier 44 as shown in Figs. 6 and 7.

When the thread has been placed in the needle in the customary manner, and the needle begins its rearward movement, the end of the latch engages the plate 45, and on continued retraction of the needle, raises up and drops over to close the needle as shown in Fig. 9. On the further retraction of the needle through the slot 37, the plate 45 rides over the top of the closed latch, and in so doing,.yields to permit the return passage of the needle beneath it. When the needle has been withdrawn completely from the slot, the springs 49, return the plate 45 to its original position.

On the frame 36 there is also arranged a latch closer consisting of a thin plate 45 provided at its lower portion with a sharp edge 46. Said edge is at its ends 47 and 48 inclined for the purpose of sliding more easily across the outwardly projecting needles 4 during the transverse movement of the slide 6 with arm 35, plate 36 and associated parts. The said plate 45 is mounted yieldingly and is pulled downwards by means of a spring 50, guided and supported by screws 51 pasing through slots 52 in the plate in such a manner, that said plate 45 is capable of moving upwards as well as a little outwards, and it is brought back to its initial position by means of a loop 49 forming part of the spring 50. Said plate 45 is preferably mounted on a separate part 55, which is adjustably connected to the frame 36 by means of a screw 56.

Claims:
