    Abstract: MAQUINA HERRAMIENTA. LA MAQUINA HERRAMIENTA CONSTA DE UN BASTIDOR (1,2,3) CON DOS ELEMENTOS DE FIJACION (22 Y 39) PARA UNA HOJA (31) DE SIERRA DE VAIVEN. EL ELEMENTO (22) ESTA ACCIONADO POR UN MOVIMIENTO DE VAIVEN VERTICAL POR UN MOTOR ELECTRICO (5). LOS ELEMENTOS (39 Y 22) ESTAN UNIDOS ENTRE SI POR UNA CINTA METALICA (45) QUE PASA POR UNAS POLEAS (46 A 50). LA POSICION DE LA POLEA (47) PUEDE MODIFICARSE MEDIANTE UNA LEVA (53) QUE ACTUA SOBRE UN BRAZO (52) PARA TENSAR LA CINTA (45) AL VALOR DESEADO.

    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: PCT No. PCT/CH84/00067 Sec. 371 Date Dec. 21, 1984 Sec. 102(e) Date Dec. 21, 1984 PCT Filed May 2, 1984 PCT Pub. No. WO84/04484 PCT Pub. Date Nov. 22, 1984.In an upper arm (1) is mounted a spindlehead (5) and in a lower frame two power takeoffs (16, 38). An electric motor (6) drives either a spindle (68) or the power takeoffs (16, 38) in rotation. Thus, the operations of milling, scroll cutting, sanding, grinding, polishing, sawing, etc., can be performed from the upper arm or the power takeoffs of the lower frame of the machine.
