    摘要: 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.

    摘要: 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.

    摘要: The presser foot has a sole hinged on an intermediate support member which is pivoted on a main support member through a deformable parallelogram of links. The main support has a yoke and screw to clamp the presser foot to the presser bar. A paw may be rigidly fixed to the main support member to hold the fabrics to be sewn when the sole is released. The sole can be drawn in the direction of passage of the fabrics when urged towards the feed dog thereby preventing relative slippage of glossy or binding fabrics. A restoring device is coupled to the needle actuating mechanism to bring the sole back into a neutral position when released.

    摘要: 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.

    摘要: A multipurpose presser foot for sewing machines comprises a sole pivotally mounted to a flange-plate for attaching the foot to a presser bar with an alignment so that, in operation, a part of the lower surface of the sole is adjacent to completed stitching. So as to facilitate passage thereunder of raised stitching, this part is retractable from the lower plane of the sole against the action of a spring. The retractable part is connected to the rest of the sole in the manner of a deformable parallelogram by means of a set of articulated members so that the retractable part, when displaced, remains parallel to the said plane.

    摘要: A system for adjusting the tensile stress to which the upper thread of the machine is subjected by means of a spring engaging an arrangement including a spindle carrying two plates between which the thread is held against friction during its progression from its spool towards the needle. The adjustment of the spring is ensured by means of two levers connecting corresponding points of the spring respectively with the spindle of said arrangement and with the cam normally controlling the actual tensioning of the spring.
