The hook () of a sewing machine () is mounted so that it can move on a hook carrier. Through a sliding movement of the hook carrier, the hook () is brought from its operating position into a bobbin case removal position. Through the sliding movement, the hook () with the bobbin case () is placed at or above the opening, which is created by the flap () in the lower arm (). In this way, the removal of the bobbin case () or the bobbin is made considerably easier.

Sewing or embroidery machine

A sewing machine wherein the fabric supporting arm or bed carries a fabric guide which is movable to any one of a number of positions at different distances from the needle. The fabric guide carries a tape measure or the arm or bed carries a ruler. The tape measure or the ruler has an eyelet for temporary attachment of the tape measure or of the ruler to the needle. The fabric guide is movable along the tape measure or ruler to a position at a desired distance from the needle. The eyelet is then detached from the needle and the tape measure or the ruler is retracted, either by hand or by a spring, to be out of the way during sewing. At such time, one edge of the fabric abuts a stop of the fabric guide while the needle makes a row of stitches at the selected distance from the edge.

Sewing machine with adjustable fabric guide

A sewing machine presser foot with a shank and a sole plate wherein the shank carries at its lower end a spherical portion extending into a complementary socket of the sole plate so that the latter is free to swivel about several intersecting axes which pass through the center of the spherical portion. A U-shaped spring couples the sole plate to the shank and limits the extent of movability of the sole plate with reference to the shank, either alone or by cooperating with two transversely extending stubs which are provided on the shank at the opposite sides of the spherical portion and extend, with freedom of vertical movement, into slots which are machined into two lateral walls of the sole plate.

Self-adjusting presser foot for sewing machines

A winding device for a sewing machine including a sewing mechanism connected to a machine drive mechanism, by a coupling which comprises, a sewing machine housing, the winding device being movable to swing into the sewing machine housing and be covered by a lid when not being used. A two-armed hinge support is pivotally disposed on the housing and connected to the lid. One arm of the said two-armed hinge support is connected by a lever mechanism with a support, and the support is pivotally attached to the sewing machine housing for the winding device forming a toggle joint such that when the lid is opened the toggle joint is pushed through and the winding device is brought into its operating position and secured there while the other arm of the two-armed hinge support disengages said coupling between the machine drive mechanism and the sewing mechanism.
