Abstract: PCT No. PCT/CH86/00110 Sec. 371 Date Apr. 10, 1987 Sec. 102(e) Date Apr. 10, 1987 PCT Filed Jul. 29, 1986 PCT Pub. No. WO87/01146 PCT Pub. Date Feb. 26, 1987.An electric sewing machine with computerized control in which the speed of rotation of the central control motor (M) is brought under the control of a regulating circuit (O, C1, Cs) comprising a control tacho generator (G), has a mechanism for driving a support for a bobbin (C) to be wound, comprising all the structural elements of the generator (G), a double action clutch (EA) allowing the rotor of the generator (G) to be connected mechanically either to said central motor (M) or to the bobbin support, electrical switching means (IE, IG) allowing, in the last case, the armature of the generator (G) to be connected to an electrical supply source (A) while preventing the central control motor (M) of the machine from being supplied with current.

Abstract: Machine à coudre à point zig-zag dans laquelle une barre porte-aiguille est engagée dans un berceau monté sur un axe de pivotement du bâti de la machine et rendue solidaire d'un tourillon relié à une bielle d'un plateau manivelle monté sur l'arbre d'entraînement principal de la machine. Des moyens provoquent un déplacement angulaire de la bielle par rapport au plateau manivelle, afin de décaler la course longitudinale de la barre porte-aiguille par rapport à la pointe d'un organe de prise de boucle et en fonction d'un déplacement latéral de la barre porte-aiguille. Un organe de liaison à coulissement relie la bielle à la barre porte-aiguille, orienté selon un axe oblique par rapport à un plan défini par les positions latérales extrêmes de la barre porte-aiguille.

Abstract: The needle bar (1) engaged in a pivoting cradle (2) is integral with a journal (3) connected by a connecting member (8) to a link (4) driven from the drive shaft (12) of the machine. In order to permit the head (23) of a loop holding member (25), mounted in the pedestal of the sewing machine, to engage in a loop (29) of the needle thread (27) during the ascending course of the needle (22), whatever may be its decentration, the connecting member (8) is formed by a bent extension of the crank pin of the link (4) engaged in a bore (7) of the journal (3).

Abstract: A sewing machine includes a stud carried by a journal surrounding a tubular needle bar having a lateral opening. A link connected to the journal normally drives the needle bar when the stud is engaged within the needle bar opening. A disconnecting rod within the tubular needle bar is axially displaceable and includes a ramp engageable with a control member, also within the needle bar, to drive the stud from the needle bar opening and thereby disengage the journal from the needle bar.
