Abstract: The device for adjusting the amplitude and direction of the feeding of the material to be sewn includes a movable element (15) provided with a set of teeth (17) for feeding. This movable element includes a slideway formed of two tracks (20a, 20b) in the form of arcs of concentric circles, one of which is generated by a cone and the other by a cylinder, both rolling on the trajectory of a shaft (12) providing a link between two levers of the drive mechanism. The two tracks (20a, 20b) of the slideway are formed by a profiled metal foil, attached to the movable element (15).

Abstract: A sewing machine is disclosed having an electric circuit divided into a first high-voltage section and a second low voltage section. The second section is supplied via a step-down transformer connected to the first section. The second section has a rectifier connected to the output of the transformer for dispensing DC power to the functional elements of the machine. The first circuit section, the transformer and some elements of the second section are contained in a remote housing which is separate from the machine and is linked to it by a cable. A foot pedal for actuating the machine is integral with the housing.

Abstract: The end of the lever (2b) ends in a fork that receives the lever (5b) between its tines (6a, 6b). Each time (6a, 6b) has a recess (9) made on its inner face. This recess (9) is parallel to this inner face and extends longitudinally of this tine, thus opening out at its end to make a passage for receiving a pivot (10). This open space (9) does not extend through the full thickness of the tines (6a, 6b), thus preserving axial stop faces for retaining the pivot (10). The end of the lever (5b) has a lateral recess (11) intended to engage the pivot (10). A draw spring (13) has one end solid with the lever (2b), while the other is caught in a groove (12) that is concentric with the axis of the pivot (10) and is made at the end of the lever (5b) opposite the side face in which the recess (11) opens.

Abstract: This contrivance includes a support (1), in which a tubular element (5) is mounted to slide, the tubular element containing a rod (6) mounted to slide in it and subjected to the action of a restoring spring (7) fixed to the support (1). At its lower end, the element (5) has two shells (10, 11) forming a cage (9) in cooperation with a belt (13) that is solid with the rod (6) and is moreover connected to the shell (11) by a second restoring spring (15). An element (17) is mounted to slide horizontally in the shell (10) and carries a hook (18) for grasping the thread, the movement of which hook is controlled by the joint action of a slideway (19), solid with the belt (13), and a dog point (17a) solid with the element (17).

Abstract: An assembly for detachably mounting a tool such as a drill, a punch or a needle for a sewing machine on a driving member. The assembly includes a tool carrier, a mounting head for connecting the tool carrier to the driving member having at least one seat surface being cooperatively engaged with a corresponding portion of the tool carrier, a device for holding the tool carrier in contact with the seat, and positioning element to place the mounting head in a specific position relative to the tool carrier when the tool carrier is held by the holding device.

Abstract: A sewing machine having a composite frame includes plastic structure forming a support base of the machine and carrying a strong U-shaped framework detachably mounted by clamps. The branches of the U-shaped framework form respectively a part of a first and a second arm, the arms being horizontal and superpositioned and projecting out from the side of a column. The drive mechanism for the needle bar of the machine and the mechanism for feed of the sewing material and for the loop pick-up device are respectively associated with these arms.

Abstract: A device for measuring the passage of a predetermined length of cloth at right angles to the needle of a sewing machine comprises a frame carrying an arm mounted about a shaft and urged resiliently towards the cloth by a spring adapted to put a pinion in contact with the cloth. A shaft carries a barrel in contact with a gear fixedly connected to the pinion, the barrel enclosing a spring. The barrel is connected to a terminal by a sliding contact and carries a pin which extends into an arcuate groove in a drum while passing through an arcuate aperture in a plate. Contact elements are disposed at one end of the groove and at one end of the arcuate aperture, the pin being able to move from one to the other of these contact elements. The contact elements press against the internal surface of a metallic ring carried by the drum, the external surface of this ring being connected to a second terminal by a sliding contact.

Abstract: In a sewing machine, a needle-bar is slidingly mounted in two bearings, the external surface of each of which has a spherical profile. The bearings are pivotably engaged in respective seats of complementary profile provided in a fixed support, for an upper bearing, and in a movable lever, for a lower bearing. This lever is alternately pivoted into two opposite positions under the action of a stepper motor. The motor drives the movable lever by engagement of a pinion with peripheral gear teeth carried by the movable lever.The motor, the fixed support, the movable lever, the bearings and the needle bar form a self-contained and detachable assembly.

Abstract: The control pedal (7) for an electric machine (3) comprises a movable member (9) connected to a foot support (11) and adapted to be actuated by the foot of the user, whose heel rests on the plate (10). When the pedal (7) is not in use, the member (9) may be lowered against the plate (10), whereas the cord (8) and that which is provided for the plug (6), are wound about the portions (12) forming bobbins.

Abstract: In a sewing machine, a thread-draw lever is driven in an oscillating movement, in synchronism with a needle bar, and carries a gripping hook for the thread, the thread being brought within reach of this hook by passing it into a longitudinal channel formed on an upper face of an upper arm of the casing of the machine.The arrangement permits the threading operation in a sewing machine to take place by simple insertion of the thread into the channel, without having to pass the thread through eyelets.

Abstract: In a sewing machine, an oscillating cradle has two bearings in which a needle bar is slidingly mounted. An external surface of each bearing has a spherical profile by which it is pivotingly engaged in a respective seat of complementary shape provided in a first arm of the cradle, for an upper bearing, and in a second arm, for a lower bearing. A resilient leaf spring, in the form of a U, exerts an axial pressure on both the upper bearing and the lower bearing, to maintain them in their seats in alignment with one another.

Abstract: The feed dog (17) for the fabric in a sewing machine is provided with a spring-wire (21) bent and passing through a hole of a support (23). When the feed dog (17) is in its upper position, the support (23) abuts the plate (18), which lowers the end (24) of the wire (21) so as to exert a tension on the lower thread (8) of the seam. When the feed dog is lowered, the wire (21) resumes its normal position, namely its end (24) is displaced upwardly with respect to the dog (17) and the thread (8) is thus relaxed.
