Abstract
A device for automatically lifting a yarn package off of a package drive roll in response to a detected condition has a vertical member depending from a package support and extending through an opening in a lever assembly. The lever assembly is selectively raised by operating means in response to a detected condition and engages the vertical member at the opening by means of the frictional force resulting from a binding action caused by rotation of a portion of the lever assembly with respect to the vertical member. In addition, the lever assembly is biased such that it is disengaged from the vertical member when the downward pressure exerted by the package and package support is relaxed.
