Abstract

An apparatus for stirring a liquid, having a stirring blade which is not only capable of rotating, but simultaneously moving in a vertical direction. The number of rotations of the stirring blade during one stoke of its vertical movement may be altered to best suit the requirements of a particular type of liquid to be stirred. The apparatus is especially suitable for stirring a highly viscous liquid uniformly.
