Abstract: A zig-zag sewing machine has a series of cams juxtaposed on a drive shaft for controlling oscillation of a needle-bar cradle. Cam selection is achieved by a manual selector having two cam profiles, one of which controls a lever to space a feeler apart from the cams at the moment when the other cam profile controls another lever to move the feeler parallel to the drive shaft to change the cam with which the feeler cooperates.

Abstract: A method for making a buttonhole in a piece of material using a zigzag stitch sewing machine wherein the lips of the buttonhole are formed by the alternate stitching of opposite fractions of the desired length of the two lips, the stitching always being carried out in the same direction, and this process being repeated until the desired length is achieved. The material is moved in the reverse direction in the period between the finishing of one fraction of two opposite fractions and the starting of the other. The method is almost entirely automatic, all movements being regulated by interchangeable cams on the machine, and operator supervision is minimal.

Abstract: An assembly comprising a presser foot and at least one graduated rule consisting of a plate hingedly secured to the sole portion of the presser foot and extending prolongation of said sole portion and in the same plane, the hinge axis extending in a direction transverse to said sole portion, the main advantage being that the presser foot is equally suitable for satin stitch, buttonholing and normal or straight stitch sewing operations without changing the presser foot when passing from satin stitch sewing to straight stitch sewing.

Abstract: A shaft has at one end, a threaded portion, a cylindrical portion and a drive bush fixed thereto. The fly-wheel is mounted to rotate on the cylindrical portion of the shaft, a clamping block being screwed on the threaded portion to clamp the fly-wheel against the drive bush to lock it in rotation on the shaft. The possible angle of rotation of the block on the shaft is limited by a screw threaded in any one of at least two bores of the block to come into cooperation with a stop finger fast in rotation to the shaft and extending radially with respect to the latter. The bores are parallel to the axis of the shaft. The screw can be positioned in that one of the bores which provides the most favourable angle of rotation of the block between the coupling position of the fly-wheel and its uncoupled position.
