Abstract
In a clothes hoist the fixed lower standard contains an aperture over which is secured a cover containing a bearing in which a driven shaft is journalled. The shaft has a handle on its outer end and a driving pinion on its inner end which meshes with a toothed nut supported by an abutment block within the fixed lower standard. The toothed nut threadably engages the worm which supports the lower end of the elevating standard such that rotation of the handle raises the worm in turn raising the standard.
