DARNING N'ELE' Gottardo Ercole Bombonato, Milan, taly Application July 7, 1950, Serial No. 172,491 In- Switzerland July 9, 1949 1 claim. 1

. This inventionV relates to a darning' needle, especially for'mending ladders in stockings, which is provided, at itsanterior extremity, with a'hook.

This needle is characterized by an oscillating member rotatably mountedl in a recess provided in the body of the needle and intended to occupy two positions, said oscillating'member being pro'- vided with a nose, a projection and a main body, said nose being situated, when said oscillating member occupies its iirst position, on the way or every thread sliding along the needle towards the hook, the projection being then hidden in said recess, while, when said oscillating member occupies its second position, the projection obturates the mouth of the hook and the nose is hidden in the recess, said main body extending along the body of the needle when said oscillating member occupies its iirst position, in such a way that a thread bearing upon it urges to hold said oscillating member in its first position.

The annexed drawing shows, by way ofexample, one embodiment of theinvention.

Figure l is a longitudinal section of a needle along line I--I in Figure 2, the oscillating member being in its rst position.

Figure 2 is a section along line II-II in Figure l.

Figure 3 is a section similar to that oi Figure 1, but the oscillating member being in its second position.

Figures 4, 5, 6 and 7 show the process of a mending work, in several phases.

The body of the needle is designated by I; it is constituted by a sheet of metal bent in such a way that the right section of this body has the form of a U, the sides of which are designated by Ia and the transversal part of which is designated by Ib. A recess I3 is provided between the sides la. The needle is ended, at its anterior extremity, by a hook. An oscillating member 3 is disposed between the sides Ia of the body I. Said member is oscillatably mounted on a pin 4 secured to the sides la. It comprises three parts: a nose 3a, a projection 3b and a main body 3c. The nose 3a has the form of a hook which is situated, when the member 3 occupies its first position, on the way oi every thread sliding along the needle, in the direction shown by the arrow 5, for entering into the hook 2. The projection 3b is then hidden in the recess I3. During this dis-` placement, the thread catches obligatory the nose 3a and drives the member 3 in rotation for bringing it into its second position, in which the projection 3b obturates the mouth of the hook 2. When the member 3 occupies its first position, its

2 main body 3 extends along the body I of the needle. The edge 3d of this main body projects out of the body I in such a way that a stitch bearing: upon itv urges to prevent the member 3 from going from. its first position into itsfls'e'cond position. A notch isprovidedfin theV sidesl. This notch has for objectY to slow' the advance of the stitch along the needle.. The member 3 is ended by a shoulder 3e intended to prevent a thread from going up along the needle beyond the body 3C. A hole l provided in the oscillating member 3 is intended to lighten said member. 8 designates a solid bar situated between the sides la and riveted at 9. This bar ensures the rigidity of the posterior part of the needle and constitutes a handle. The hook 2 is made thinner at IIJ, slightly under the axis of the needle, so that the thread situated in this hook occupies this thin place Iii, what makes easier the operation of the needle.

This operation is the following:

The needle is introduced in a stitch II, ready to be dropped, under the last stitch which has already been dropped, designated by I2. The stitch II abuts against the projection 3b and brings the member 3 into its first position. It is necessary to drive the needle rather deeply so that the stitch l I reaches at least the notch 6 it may even reach the body 3c of the member 3; during this movement, the thread l2 came behind the nose or hook 3EL (Figure 5). The needle is then pulled out. The threads I I and I2 slide simultaneously along the body of the needle, in the direction of the hook 2. The thread I2 enters into the hook 3e (Figure 6). The member 3 is prevented from oscillating by the stitch II whichvbears on the edge 3d of the body 3C. A certain tension of the thread I2 then takes place. As soon as the stitch II has passed the bottom of the notch 6, the member 3 is released and occupies rapidly its second position, the hook 3a entering into the recess for hiding therein. This hook 3a leaves then the thread I2 which is situated at the mouth of the hook 2 and is thus obliged to enter into it. The tension of the thread I2 prevents it from leaving prematurely the hook 3a. During the rotation of the member 3, the projection 3b passes before the stitch II and obturates the mouth of the hook 2, so that the stitch II leaves the needle (Figure 7). If the thread I2 had accidentally not entered into the hook 2, the member 3 had not begun to rotate and it would be the stitch II which should have entered into the hook 3a and then into the hook 2 (Figure 4). The operation should have to be done again, but the stitch Il should not have been dropped.

The stitch Il thus cannot leave the needle before the thread l2 has entered into the hook 2.

In all the needles known up until today, the most frequent wrong operation, viz. the noncatching of a thread, produces the outlet of the thread out of the needle and consequently the dropping of the just formed stitch and generally of several other stitches;

The needle does not present this drawback and can be operated without entailing an apprenticeship. A wrong carried out operation has simply to be repeated, without the work precedently carried out being disturbed.

What I claim is:

In a darning needle, especially for mending ladders in stockings, ended at its anterior extremity by a hook, a body of this needle, a recess in said body, an oscillating member rotatably mounted in said recess and intended to occupy two positions, said oscillating member being provided with a nose, with a projection and with a main body and said oscillating member being arranged in such a way that when it occupies its first position, said nose is situated on the way of every thread sliding along the needle towards the hook, and the projection is then hidden in said recess,

while, when said oscillating member occupies its second position, the projection obturates the mouth of the hook and the nose is hidden in said recess, said main body extending along the body oi the needle when said oscillating member occupies its first position, in such a way that a thread bearing upon it urges to hold said oscillating member in its rst position, the main body of said oscillating member ending by a shoulder intended to prevent the thread bearing upon said main body from going up along the needle beyond said main body.
