Abstract: An ironing press of the type wherein the stationary ironing board is heated by a heating plate lowered onto it by an arm pivotally secured to the press body. To allow freedom of movement in all directions of the heating plate with reference to the ironing board, there is associated with a central multidirectional pivotal connection between the heating plate and the carrier arm, an elastic connection constituted by coaxially bored bosses raised on the plate, the bores in said bosses being engaged by pivots elastically fitted on the carrier arm at points lying with the pivotal connection on a line parallel with the pivotal axis between the heating plate and the carrier arm.

Abstract: In an ironing press a common knob controls simultaneously the adjustment of a thermostat in accordance with the temperature to be reached by the ironing plate according to the material to be ironed and the progression of a tape which is thus caused to move between a source of light and a panel provided with a translucent strip and with symbols corresponding to the temperature required for these different materials. A line separating two successive transparent and opaque sections of the tape is thus automatically brought into registry with the symbol corresponding to the temperature for which the thermostat is adjusted at the same time.

Abstract: A sewing machine case comprises a rectangular box-like hollow pedestal to the upper edges of which are hinged four flaps. A base and lower free arm of the sewing machine can be removably housed in said pedestal, the free arm fitting in an opening in the upper surface of the pedestal which forms, with the flat upper surface of the free arm, a small work table. In a lowered position the flaps form access slopes to this table, a cover hinged on one flap being folded thereunder to hold the flap in the plane of the table. The flaps can be folded up and fixed to the cover to close the case around the machine.

Abstract: A zigzag stitch sewing machine has the lateral displacement of the needle actuated by a cam selected from a stack of cams mounted in fixed and/or removable manner on a common shaft to which they are secured for rotation with the shaft. The shaft is rotated by the principal drive shaft of the machine ensuring the to-and-fro movement of a needle bar into a pivoting cradle, the cam ensuring the pivoting of the cradle by means of a transmission element. The transmission element comprises a lever hinged to the frame and provided with a feeler in contact with the profile of said cam, a rod driven in a sliding movement, hinged to the cradle, and an intermediate element displaceable between a support surface presented by said lever and a ramp axially rigid with said rod. The intermediate element is loosely mounted on the rod around which it is movable over a circular arc. The ramp is the profile of a cam mounted on said rod.

Abstract: An ironing press wherein the heating plate suspended to a pivoting arm is adapted to be lowered onto and raised above the ironing area, and wherein a hand-operable lock may be rocked into a position wherein a bolt carried by it engages a groove in the arm so as to lock the lever in the position it assumes inside the groove when it urges the arm downwardly. Furthermore, the lowering of the arm acts mechanically through the lever or through said lock on an electric circuit so as to disconnect the latter from the heating means which it energizes inside the heating plate and to connect it with an alarm circuit. A delay system is advantageously incorporated with said circuit to delay said switching operation a few seconds after the lowering of the arm and plate.

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 flywheel 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.

Abstract: The presser foot has a sole plate pivoted by an axle to a support attached to the presser bar. A portion of the sole plate behind the needle passage hole is upwardly retractable against the action of a spiral spring and is suspended from the axle. Stops, formed by a transverse rod fixed in the sole plate between the needle passage hole and the retractable portion and by an inner edge of the sole plate, limit the oscillation of the retractable portion. The spring is housed in the retractable portion and bears against the axle. Vertical grooves in the retractable portion act as vertical guides. The parts of the foot can be of plastics material.

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 mechanism for a sewing machine for enabling the manual or automatic control of the direction and of the amplitude of movement of a transporting claw guide for material to be sewn. The mechanism is driven from the main driving shaft of the sewing machine via a cam and a series of intermediate lever members connected to a rotatable shaft connected to the transporting claw guide. The control is automatically accomplished by means of a cam driven from the main driving shaft of the machine via the arrangement of levers to obtain back-and-forth movement of the claw guide or, when a cam follower is disengaged from the cam, the control can be accomplished manually without the automatic back-and-forth movement.
