This invention relates to a work holder especially for knitting machines for mending knitted, Woven or similar articles. 'The holder is pivoted to the needle bed of the machine frame andcan be moved on its pivots transversely to the needle bed against the action of a spring.

The. drawing illustrates a constructional form for carrying out the invention.

Fig.1 is a cross section of the interesting parts of the knitting machine.

Fig. 2 is a partial View showing the work holder with the work attached thereto. 7

Fig. 3 is a front view showing the holder and work looking from the right hand side of Figure 2.

Figs. 4 and 5 show a modification. 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 reciproeatory movement actuated by usual cams on a slide 6. 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 transverse- 1y above these fingers 8 there is arranged an upwardly yielding latch opener 9 which is plvotally connected at 13 to the needle bed extension 3.

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 can be swung transversely against the pressure of a spring 24. The work 21, in which for instance a hole 27 is tobe mended, is stretched on the holder (Figures 2, 3) 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 (Figure 3) The work, for instance a stocking, is fastened to the holder preferably by means of an endless spring 30-orby other elastic means such as a rubber band, which is pulled over the work around the root of the work holder. During the work- 50 ing operation the work holder is loaded by weights so as to turn step by ste on the pivots 22,23 in a manner similar to t at 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 a frame 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 frame is provided at its lower part with a longish opening 37 through which the needles 4 at their working operation are penetrating. As the work is located between said frame 36 and the holder 20 the frame 36 will prevent the work from being thrown outwards by the needles.

The holder 20 may be swung on the pivots 23 transversely of the needle bed against the action of the spring 24. The holder is formed as a box open in opposite ends and the needle bed projects through said openings, which are a little wider than the width of the needle bed. Between the walls 28 and fixed to them the holder may be provided with ribs 58 (Figs. 4 and 5) serving as a support for the work, these ribs being parallel and being spaced apart in order to allow the passage of the nee-dles. The ribs 58 are formed on a curve having its center in the pivots 23 of the holder.

Claims:

1. In a machine for mending knitted fabrics, having a needle bed provided with a plurality of reciprocating needles, a spring biased work supporting device pi votally mounted on said needle bed along an axis perpendicular to the path of said needles and substantially in the plane of the needle bed, said device being adapted to be moved about said axis against the action of said spring to carry the supported work in a direction transverse to the path of said needles.

2. 'Apparatus according to claim 1, wherein said work supporting device comprises a box-like member open at both ends and extending in the direction of the needles, said member being mounted with its outer open end substantially in coincidence with the outer edge of the needle bed.

3. Apparatus according to claim 1, wherein said work supporting device comprises a box like member open at both ends and extending in the direction of the needles, said member being provided with a plurality of spaced ribs extending across its outer open end whereby the (portion of the work extending across sai outer end is sup orted against the pressure of the needles uring their passage therethrough.

In testimony whereof I have signed my name to this specification.

DAG TORGERSEN.
