xn rf'rme NEEDLE Filed Aug. 30, 1939 Imam/r0 flame l oeck Patented Mar. 25, 1941 PATENT OFFICE KNITTING NEEDLE Theodor Vorck, London, England, assignor to United Elastics Limited, London, England Application August 30, 1939, Serial No. 292,698 In Great Britain September 9, 1938 6 Claims.

This invention relates to knitting and like needles and more particularly to needles for use in knitting machines and in shuttleless looms for knitting and weaving fabrics having a selvedged edge, warp knitting machines and crochet machines.

One of the objects of the invention is to provide a needle of such a construction that failure to engage the weft or selvedge threads is obviated.

Another object of the invention isto provide a yieldable thread guide arranged in spaced relation to the needle but movable therewith and adapted to engage and direct the weft or selvedge thread into the hooked or similarly shaped portion of the needle.

A further object of the invention is to provide a yieldable thread guide which may be fixed to a member carrying the needle or which may be secured to the shank of the needle itself.

A still further object of the invention is to provide a yieldable thread guide which comprises a piece of bent spring steel wire or strip which is arranged alongside the needle and extends towards the hooked end thereof. At the hooked end of the needle it passes below the needle hook and is then bent up beside the hook and finally extends forwardly and upwardly beyond the front of the hook to engage and direct the thread into the hook as the needle is reciprocated. Various forms of guide member are possible. The needle and guide member are preferably carried in spaced relation on a holder block or thelike adapted to be mounted for reciprocation in the loom frame.

To. enable the invention to be fully understood it will now be described with reference to the accompanying drawing which shows perspective large scale views of several forms of the invention:

Fig. 1 shows a loom part carrying a latch needle andhaving a guide member accgrding to one form of the invention attached thereto, and Fig. 2 is a similar view but showing a modified form of guide member.

Fig. 3 is a view showing a loom part carrying a latchneedle and two guide members according to the invention.

Referring to Fig. 1 a holder or block I adapted to be mounted for reciprocation on a loom carrles a latch needle 2 of known construction and a yieldable spring steel wire thread guide member 3 is also arranged on the block in spaced relation to the needle. The guide 3 is parallel to the needle and at the point 4 adjacent to the latch. 5 is bent downwardly and at the point 6 upwardly and forwardly so that the free end '1 extends above the needle hook 8.

In use, as the needle is advanced towards the weft thread as it is laid by the weft laying mechanism the .free end I of the guide member 3 meets the thread and .is lifted thereby and as the needle advances the thread passes over the needle between it and the guide as the needle recedes the part 6 of the guide presses on' the thread and ensures that it is directed into the 10 hook 8 of the needle. If desired the needle may be arranged between two guide members such as 3, the operation being as above described for the one member.

In the construction shown in Fig. 2, the yield- 15 able guide member 3a is bent into a W-shaped curve at 9 the free end I'0 extending upwardly as in Fig. 1 As the needle is advanced the end In is lifted by the thread and deflects it downwardly on to the needle, and then as the needle advances 20 further the thread is pressed into the V-shaped bend II which ensures that the thread will enter the needle hook as the needle and guide member recede. Again two guide members 3 may be provided one on each side of the needle if desired. 25

In the construction shown in Fig. 3 two

yieldable guide members

3, 3a are provided one on each side of the needle 2, the guide 3 being shaped as in Fig. 1 and the guide 3a as in Fig. 2. These guide members operate in the manner described above.

It will be understood that other shapes of yield- ,able guide members may be devised and that in all cases, if desired, the gu de member or members may be secured to the needle shank 2a and suit- 35 ably spacedtherefrom instead of being mounted on a holder or carrier as shown in the drawing.

The yieldable guide members may be used with needles of various kinds, such as bearded needles, crocket needles or with any other needles or like 40 devices used in knitting machines or in selvedge forming attachments for shuttleless looms.

Further a suitable needle and yieldable thread guide according to the invention, may be mounted in a handle and used for repairing knitted goods 45 by hand as will be understood.

While the thread guide members arepreferably made of spring steel wire or strip they may be made of other suitable material.

I claim: 50

1. In a needle loom of the type comprising a needle holder and means for reciprocating the holder,'a needle having a hooked end mounted in the holder, a yieldable thread guide attached to the holder and arranged alongside the needle but in spaced relation thereto to guide the thread into the hooked end thereof.

2. In a needle loom of the type comprising a needle holder and meansfor reciprocating" the holder, a needle having a hooked end mounted in the holder, a piece of bent spring wire fixed to the holder and extending alongside the needle to the hooked end thereofwhere it is bent downwardly and then forwardly and upwardly beyond the hooked end to direct the thread -.into saidhooked end as the needle is reciprocated.

3. In a needle loom and in combination, as

'claimed in claim 2 an arrangement wherein the thread guide comprises a piece of bent spring wire arranged alongside the needle and extending towards the hooked end thereof, the wire being bent below the needle hook at the endthereof and then bent up beside the hook and extending forwardly and upwardly beyond the front of the hook to engage and direct the thread into the relation to the needle and extending alongside the needle to the hooked end thereof where it i is bent downwardly and then forwardly and upwardly beyond the hooked end to direct the thread into said hooked end as the needle is reciprocated.

5. In a needle loom of the type comprising a needle holder andmeans for reciprocating the holder, a latch needle having a hooked end mounted in the holder and two yieldable guide members secured to the holder one on either side and parallel to said needle but spaced therefrom and arranged to direct the thread into the hooked end of the needle when the needle is reciprocated.

6. In a needle loom of the type comprising a needle-holder and means for reciprocating the holder, a' needle having a hooked end mounted in the holder and a. piece of bent spring wire arranged alongside the needle and extending towards the hooked end thereof, the wire being bent below the needle hook at the end thereof and then bent up besidethe hook and extending forwardly and upwardly beyond the front of the hook to engage and direct the thread into the hook as the needle is reciprocated.
