    摘要: When a sewing machine is stopped, it is electrically indicated whether a needle is positioned at a range where the thread passing is available so that intermittent indication during stitching operation is not made. The sewing machine is provided with a device including a neon lamp and a light interrupting member. The sewing machine has on its exposed front surface lighting indicators which are illuminated by the light of the neon lamp if this light is transmitted by the interrupting member which is mounted on or in the vicinity of the movable device for vertical movement of the needle so that the indicators indicate in the inoperative position of the sewing machine that the thread may be passed in a thread passing device.

    摘要: For a hem stitching operation with a sewing machine having a needle vertically reciprocating and also laterally swingable, a hem stitching presser foot is detachably mounted to a lower end of a presser bar of the sewing machine. The presser foot includes a brush like element which confronts a needle dropping hole formed in a sole of the presser foot, a frictional contact between the needle and the brush like element is produced when the needle passes the outside of the fabric edge, without penetrating the fabric, to stitch a portion of hem stitches on the outside of the fabric edge. The brush like element may be secured to the sole of the presser foot, or alternatively to a fabric guide member for engaging and guiding the fabric edge. The brush may be projected in the fabric feeding direction or across the fabric feeding direction. A pin may be located just beneath the brush like element for constant placement thereof.

    摘要: A selecting device for a double-function sewing machine having a single drive motor with the sewing machine including a first stitch forming mechanism to produce one type of stitch, a second stitch forming mechanism to produce another type of stitch, and a transmission for transmitting the rotation of the drive motor to the first and second stitch forming mechanism. The selecting device includes a first clutch operated into an operative position to contact the first stitch forming mechanism to a transmission and operated into an inoperative position to disconnect that mechanism from the transmission, and a second clutch operated into an operative position to connect the second stitch forming mechanism to the transmission and operated into an inoperative position to disconnect that mechanism from the transmission. A manually operated dial is mounted on the housing of the sewing machine, which is connected to a lever mechanism operated in one direction to hold the first mentioned clutch in the inoperative position and release the second clutch into the operative position. The lever mechanism is manually operated in another direction to hold the second clutch in the inoperative position and release the first clutch into the operative position.
