    摘要: In a two-needle sewing machine for making an ornamental stitch without a cover stitch, at least one intermediate lug (17) is provided which is disposed in side by side relation with respect to an upper thread take-up (13) engaged to the needle bar (7), said intermediate lug, in the absence of a workpiece (4) on the needle plate (8), is brought to a work position in which it interferes with one of the needle threads (4a, 4b) coming from an auxiliary thread take-up (12) being part of a feed unit for the needle threads. In the presence of the intermediate lug (17) in the work position, the orientation of the needle thread (4a) intercepted by said intermediate lug is suitably deviated with respect to the upper thread take-up (13), so as to cause a tension release on the needle thread itself during the raising steps of the needles (3a, 3) towards the upper dead center of their reciprocating motion.

    摘要: A work feed device for sewing machines, which comprises feed dog carrier bars performing an elliptical movement with the aid of two mechanisms; namely, an advancing mechanism and a raising mechanism. The advancing mechanism is composed of an oscillating shaft provided with arms, which in turn are connected to the feed dog support bars at the opposite end to that where the dogs are mounted. The raising mechanism comprises a support making a vertical reciprocating movement and which is provided with a horizontal guide along which the feed dog support bars are moved reciprocatingly by the advancing mechanism. Finally, vertical movement of the support comprises two connecting rods approximately parallel to one another. They are pivoted at one end to the said support and at the other end to a part connected to the frame of the sewing machine.

    摘要: An improved device for operating a needle in a sewing machine having a needle supporting clamp that is guided for sliding movement in a vertical plane by a needle bar. The needle bar is pivotably mounted on and depends from a support member which causes it to automatically align itself and follow the effective path of travel of the needle supporting clamp. The support member is mounted on the machine frame and is eccentrically positionable which provides a means whereby it can be selectively located in a position whereat the needle bar depending therefrom will never be subjected to more than a minimum amount of resistance by the needle supporting clamp during the latter's sliding movement thereon.

    摘要: A sewing machine comprises a bed 3 on which a work-supporting table 3a is defined and from which a post 4 carrying a cantilevered support arm 5 provided with a needle-holding head 6 at its free end, rises up. An upper shaft 9 performing a rotating motion is housed within the arm 5 and it imparts a reciprocating movement, through a connecting rod-crank linkage 10, to a needle bar 11 vertically slidable in the head 6. Along the upper shaft 9 a plurality of eccentrics 19, 20, 21 are distributed to which auxiliary sewing operation devices 22, 32, 39 detachably associated with the sewing machine 1 are operativley engageable through respective connecting rods 23, 33, 50 and transferring motion mechanisms. A preformed opening 5 is formed in the support arm 5, through which connecting rod 50 is mounted to eccentric 21. An opening 36 is formed in support arm 5 through which stem 37 passes. As a result of the preformed openings in the support arm and the eccentrics along the upper shaft, the sewing machine of the present invention provides for the connection of auxiliary sewing operation devices, through the preformed openings, and to the eccentrics on the upper shaft of a basic version of the sewing machine.

    摘要: A presser foot having a shoe comprising a pair of mutually facing front portions (5a, 5b) and a pair of rear portions (6a, 6b) in alignment with the front portions (5a, 5b) and connected thereto by a pair of side rocker arms (7a, 7b). The side rocker arms (7a, 7b) are pivotably supported by swinging arms (10a, 10b) linked to a small bearing frame (2). A center rocking arm (15) mounted on the bearing frame (2) acts by a pair of laterally disposed pistons (17a, 17b) on the individual swinging arms (10a, 10b) in order to mutually balance the fulcra of the side rocker arms (7a, 7b). Operating at a longitudinal opening (29) defined between the front portions (5a, 5b) is a fixed knife (32) and a movable knife (33) which are adjustable independently of each other in their vertical positioning relative to the shoe (4).
