Constructed with two handles operating at the same time, so that the material, wet, oily or dry, may be ground easier and faster.
      The cranks are secured on the shaft at right angle to each other so that there can be no pulling on a dead center, but the power of each hand is exerted fully all the time giving the body of the operator an easy rocking motion which does not tire as much as when operating with a single crank.
      The mill has a cylindrical column with a base constructed in such a manner as to be fastened by three screws to a counter, table, etc. The case, containing the feed screw cast upon the shaft, is fitted to the top of the column and is held there by two bolts with wing nuts. To the open end of the case is bolted a plate which closes the end of the: case and makes it into the form of a hopper and is provided with a circular opening through which the material to be ground is forced into the grinding discs by the feed screw.
