Abstract (en)

This device comprises a support (1) in which is slidably mounted a tubular element (5) containing a rod (6) which is slidably mounted in this element and subjected to the action of a return spring (7) fixed to the support (1). The element (5) carries, on its lower end, two shells (10, 11) forming a case (9) interacting with a belt (13) integral with the rod (6), which case is attached, moreover, to the shell (11) by means of a second return spring (15). In the shell (10) is horizontally slidably mounted an element (17) carrying a hook (18) for gripping the thread, the movement of which is controlled by the conjugate action of a slide (19), integral with the belt (13), and of a stud (17a) integral with the element (17). <??>Any relative displacement of the shells (10 and 11) and of the belt (13) leads to an axial movement of the element (17) along a path such that the hook (18) is made to pass through the eye (c) of the needle (4) in order to catch hold of any thread placed on a support (22) integral with the element (17) which is fixed to the shells (10 and 11) of the case (9). <??>This device may be used for threading a thread into the eye of the needle especially of a sewing machine. <IMAGE>
