    • A thread guide device for use with sewing and embroidering machines is adjustable to accommodate a variety of differently dimensioned thread spools or cones and is adapted for use with machines having a horizontally disposed thread spool support rod. The thread guide device includes a base having a support rod for supporting a spool or cone of thread on a rotor journalled for rotation on the support rod and dimensioned for insertion into the core of a spool or cone of thread. The rotor has a tapered end portion for accommodating spools or cones of different sizes. A wire loop thread guide secured to the base and mounted for selective lateral adjustment relative to the support rod has a first portion disposed within a slot of a slotted arm and a second portion provided with a coil wrapped around the slotted arm. A set screw secures a tapered retaining cap having a central axial aperture receiving the support rod to the support rod. A free floating thread retaining ring placed over an upper portion of a core of a thread spool or cone, allowing thread to be fed between the retaining ring and the core. A support ball mounted in an adjusted position along on the support rod by a set screw limits off-center movement of a thread spool or cone. The thread guide may be mounted on a ball having a cylindrical aperture slidably receiving the adjustment rod therethrough, such that the thread guide is selectively and independently adjustable in two perpendicular linear directions and also mounted for selective and independent adjustment around a first axis of rotation and a second perpendicular axis of rotation.
    • 用于缝纫和绣花机的导线装置是可调节的,以适应各种不同尺寸的线轴或锥形,并且适用于具有水平布置的线轴支撑杆的机器。 导丝装置包括一个底座,该基座具有支撑杆,该支撑杆用于支撑转子上的线轴或锥体,所述转子被安装在支撑杆上以便旋转并且被设计成用于插入线轴或螺纹锥的芯中。 转子具有用于容纳不同尺寸的卷轴或锥体的锥形端部。 固定到基座并安装成用于相对于支撑杆进行选择性侧向调节的线环线引导件具有设置在开槽臂的槽中的第一部分和设置有缠绕在开槽臂上的线圈的第二部分。 固定螺钉将具有中心轴向孔的锥形保持盖固定到支撑杆上。 一个自由的浮动螺纹保持环放置在螺纹卷轴或锥体的芯的上部上,允许螺纹在保持环和芯之间供给。 通过固定螺丝沿着支撑杆安装在调节位置的支撑球限制了线轴或锥体的偏心运动。 导丝器可以安装在具有可滑动地接收调节杆的圆柱形孔的球上,使得线引导件在两个垂直的线性方向上选择性和独立地可调节,并且还安装成围绕第一旋转轴线进行选择性和独立的调节, 第二垂直旋转轴。
