US 10,293,382 B2 · Plant trimming shear cleaner and sharpener

Abstract

The invention is a convenient and portable device for cleaning and sharpening cutting tools for gardening such as pruners, clippers, snips, or shears when these have become fouled from working on plants which exude gummy residue or sticky sap when cut. The device includes a reservoir for holding cleaning solutions, at least one motor driving a planetary or epicyclic gearing or slippable roller drive mechanism, to rotate at least one disc so that bristles of the disc process along roulette paths which include a hypocycloid, an epicycloid, a hypotrochoid, or an epitrochoid. A motor switch detects the insertion of a gardening cutting tool and turns on the motor after a predetermined delay and for a predetermined duration. The cutting tool must be removed for the switch to be reset. The cleaning machine can be powered by internal batteries or external power.
