摘要： A device for retaining or confining a magnetically-supported false-twist spindle within the magnetic field supporting it, including the combustion of: A. A base plate having mounting means for positioning and securing the device in proximity to the spindle to be retained; B. A hinge plate secured to the base plate by pivot means for providing pivotal movement of the hinge plate from a vertical position in proximity to the spindle to a horizontal position away from the spindle. The hinge plate terminates at its free end in a shield section which faces and is located in close proximity to, but not touching, the spindle when the hinge plate is in the vertical position; C. A locking lever having a single bend spaced from its medial point and pivotally mounted on the side of the hinge plate away from the spindle, so that the bend functions as a fulcrum. The upper end of the locking lever extends beyond the upper end of the hinge plate, and the lower end of the locking lever is positioned in proximity to an edge of the base plate, as a result of which the lower end of the locking lever rests on the base plate when the upper end of the locking lever is urged away from the spindle and the lower end of the locking lever is raised above the plane of the base plate and beyond an edge thereof when the upper end of the locking lever is urged toward the spindle; and D. Resilient means, which urges the upper end of the locking lever away from the spindle.
