2 Claims. (Cl. 223-102) This invention relates to improvements in sewing needles.

The ordinary sewing needles are made in a variety of sizes ranging from very small embroidery needles to darning and sail makers needles. Some of the smaller needles are difficult to thread due to the small or narrow eyes and unless the operator is gifted with keen sight and steady nerves or employs a mechanical device to aid him, much time is consumed in the operation of making a thread pass through the eye of a sewing needle of the smaller sizes.

This invention relates to an improved construction of sewing needles whereby the thread is directed into the needle eye with much less effort than formerly. Another object of the invention is to produce a needle that can be pulled through a piece of heavy cloth without oifering any appreciable increased resistance to the passage of the eye portion and the bight of the thread sewed.

In a general way the needle is designed for a new technique in the operation of inserting a thread through the eye of a needle. The invention, very briefly described, consists in providing the eye end of the needle with a transverse notch that communicates with the eye by oppositely positioned depressions, and in which the notch at the end is separated from the eye by a solid wall.

Having thus set out the principal objects of the invention and described in a general Way its construction, the invention will now be described in detail, for which purpose reference will be had to the accompanying drawing in which the invention has been illustrated, and in which Figure l is a side elevational view looking toward the eye and shows the notch at the end of the needle;

Figure 2 is a section taken on line 2-2 Figure 1 and shows in addition how the end of the thread is positioned in the end groove in position to be moved into the eye and inserted therein;

Figure 3 is a partial section also taken on line 22 Figure 1 and shows the thread inserted in the eye;

Figure 4 is a side elevational view similar to that shown in Figure 1 but to an enlarged scale;

Figure 5 is a section taken on line 5-5 Figure 4 and shows the initial position of the thread by full lines and the position of the thread after the end has been inserted in the eyeiby broken lines;

Figure 6 is a side elevational view looking in the direction of arrow 6 in Figure 4 and shows the initial position through the material of the thread by broken lines, full lines;

Figure 7 is a top Figure 4;

Figure 8 is a section taken on line 88 Figure 6, and

Figure 9 is a section similar to Figure 5 and shows the position of the bight of the thread when the needle is in use.

Referring now to the drawing, reference numeral 10 designates the needle in its entirety and 11 designates the eye which has been shown as elongated in the direction of the axis of the needle. Reference numeral 12 designates the notch in the end of the needle. The ends of notch 12 are joined to the eye by grooves 13 whose depth is equal to the width of the eye so that the thread 14 will not project beyond the side of the needle when pulled into a bight like that shown in Figure 9 and will therefore not add to the resistance offered to pulling the needle through the material. The bight of the thread passes around the solid portion 15 which connects the sides on opposite sides of the eye.

Attention will now be the notch 12 and the needle.

Referring in particular to Figures 2 and 5, it will be seen that the end of the thread is first laid in notch 12 and it is then moved downwardly in the direction indicated by arrow 16 until the end passes to the underside of part 15 whereupon the end of the thread enters the eye and can then be pushed through the eye as shown in Figures 3 and 6. The notch 12 and grooves 13 serve as guides for the thread directing it into the eye.

Since the diameter of the needle is ordinarily twice the diameter of the eye and since notch 12 is almost as wide as the diameter of the needle, it is not difiicult to position the thread in the notch. A considerable length of thread is used in making the contact and by sliding the thread downwardly the end enters the eye as above explained. In the usual way of threading a needle the end of the thread is pointed towards the eye and it is quite diflicult to make the thread enter the eye. With the new technique no great amount of care is needed after the thread is laid in the notch as it will be guided into the eye as it is pulled downwardly.

What is claimed as new is:

l. A needle having an eye near its butt end and provided in its butt end with a diametrical notch parallel with the eye, the notch and the eye being spaced by a connecter integral with the material of the needle, said connecter having its sides provided with grooves communicating the notch with the eye, forming guides directing the end of a thread into the eye.

2. A needle in accordance with claim 1 in which the notch in the butt end is outwardly flaring and has a maximllll'l width substantially equal to the diameter of the nee e.
