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.
摘要翻译：对于具有针垂直往复运动并且横向摆动的缝纫机的下摆缝合操作，缝合缝纫脚可拆卸地安装到缝纫机的压杆的下端。压脚包括与形成在压脚的鞋底中的针落下孔相对的刷状元件，当针穿过织物边缘的外部时，产生针和刷状元件之间的摩擦接触，而不会渗透到织物，在织物边缘的外侧上缝合一部分皱纹针迹。刷状元件可以固定到压脚的底部，或者可选地被固定到用于接合和引导织物边缘的织物引导构件。刷子可以在织物馈送方向或织物馈送方向上投影。销可以位于刷状元件正下方，用于恒定放置。

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.
摘要翻译：一种具有单个驱动马达的双功能缝纫机的选择装置，该缝纫机包括用于产生一种线圈的第一线圈形成机构，产生另一种线圈的第二线圈形成机构，以及用于传送驱动马达旋转到第一和第二线圈形成机构。所述选择装置包括：第一离合器，其操作成操作位置，以将所述第一线圈形成机构接触到变速器并且操作到不工作位置以将所述机构与所述变速器断开;以及第二离合器，其操作成操作位置以连接所述第二线圈形成机构到变速器并且操作到不工作位置以将该机构与变速器断开。手动操作的刻度盘安装在缝纫机的壳体上，其连接到在一个方向上操作的杠杆机构，以将第一离合器保持在非操作位置，并将第二离合器释放到操作位置。杠杆机构在另一方向上手动操作以将第二离合器保持在非工作位置，并将第一离合器释放到操作位置。
