AV. In FIG. 2. The specified device consists of a swiveling, hinged metal holder on the hinge, 1, the lower part of which, carrying a thin hook 4 used for threading a thread into the eye of a sewing needle, is made in the form of a clip 6 that is adjustable in part to the holder 1 and fixed screw 7 with a head, and. designed for proper interposition of the needle and hook 4 in the case of injection.

To facilitate the hooking of the thread to the hook on the holder, protrusions 5 are provided. The holder 1, with its upper part, is put on the roller 10, mounted on the side of the sewing machine arm, on which the usual adjuster 9 is put on to tension the thread and the spring-loaded lock washer 11.

The device operates as follows. .

When the thread is broken, by pressing on the footrest of the sewing machine, the needle lowers somewhat. The needle, falling between the branches of the 3 forks, is precisely located in the plane perpendicular to the movement of the hook, which also is directed into the eye of the sewing needle.
