Date Dec. 1, 1988.The machine tool comprises a frame (1, 2, 3) with two fixing elements (22 and 39) for fastening a scroll saw blade. The fixing element (22) is driven by an electrical motor (5) in a vertical reciprocating movement. The two fixing elements (22 and 39) are linked to each other by a metallic ribbon (45) passing on pulleys (46 to 50). The position of the pulley (47) can be changed by means of a cam (53) acting on an arm (52) so as to stretch the ribbon (45) to the desired value.

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 has a frame formed of a base, a column, a lower free arm having an upper working surface, an upper arm and a head. A material supporting means in the shape of a retractable shelf is connected to the base by a set of articulated parts, this shelf being displaceable in a vertical direction between an operative level in which it fits around the lower free arm at the working surface thereof, and a retracted level below the lower free arm to allow access thereto. Flaps are hinged to this shelf and can be folded against the frame to form a case therewith or can be folded down to allow access to the machine for operation thereof.
