Abstract
A device for cleaning or refining herbage or herbal substances which operates to separate out twigs, seeds or other roughage by an agitating and straining process. The device includes a cylindrical main body internally divided into a pair of chambers by a fixed strainer or wire screen with a pair of removable end caps enclosing the chambers at each end of the cylinder. A plurality of metallic balls, preferably four, are loosely confined within one of the chambers within which the herbage to be refined is introduced. Vigorous shaking of the device will cause refined herbage to pass from the chamber containing the balls, through the strainer or screen and into the other chamber where the refined herbage may be collected in one of the end caps.
Claims4
A device for refining herbage comprising a hollow cylinder, strainer means fixedly mounted within said cylinder and extending transversely thereacross to divide said cylinder into a first and a second chamber, and a plurality of generally spherical balls loosely confined within said first chamber, said device operating upon placement of herbage in said first chamber together with said balls and upon subsequent agitation of said device to collect refined herbage in said second chamber after passage thereof from said first chamber through said strainer means, wherein said hollow cylinder is formed in a first and a second part, said second part having a stepped configuration with a first cylindrical wall of smallest diameter, a second cylindrical wall of intermediate diameter and a third cylindrical wall of largest diameter;
- wherein said strainer means is formed in a cup-shaped configuration arranged to be slidably emplaceable and to fit over said first cylindrical wall;
- and wherein said first part of said hollow cylinder is formed with a diameter generally coinciding with the diameter of said third cylindrical wall and fitted over said second cylindrical wall to hold said strainer means against said first cylindrical wall, said first part of said hollow cylinder also comprising an annular flange extending completely thereabout and located to press said strainer means against said first cylindrical wall when said first and said second parts of said hollow cylinder are assembled together.
