Cordless pepper mill

A cordless pepper mill, comprising:

• an elongated housing having a bottom end;
• a plurality of slits in said bottom end for discharging pepper flakes;
• a mill in said housing for grinding pepper corns into pepper flakes;
• said mill being frusto conical in shape and having larger and smaller diameter ends, said larger diameter end of said mill directed toward said bottom end of said housing and said smaller diameter end of said mill directed away from said bottom end of said housing, such that said mill tapers in diameter inwardly away from said bottom end of said housing;
• means mounting said mill for rotation with a minimum clearance within an oppositely tapering frusto conical seat;
• said seat having a smaller diameter end directed toward said bottom end of said housing and a larger diameter end directed away from said bottom end of said housing, such that said seat tapers inwardly in diameter toward said bottom end of said housing;
• said mill having a plurality of circumferentially spaced alternating trapezoidal lands and trapezoidal flutes;
• said lands and said flutes each having a flat trapezoidal face and two flat trapezoidal side walls, said side walls forming a right angle with said faces;
• said trapezoidal flutes tapering in depth from a maximum depth adjacent said smaller diameter end of said mill to a minimum depth adjacent said larger diameter end of said mill;
• said trapezoidal lands and said trapezoidal flutes tapering in width from a largest width adjacent said larger diameter end of said mill to a smallest width adjacent said smaller diameter end of said mill;
• a motor in said housing;
• a gear reduction unit connected to a rotary output shaft of said motor;
• a rotary output shaft of said gear reduction unit connected to said mill;
• a rechargeable battery in said housing for driving said motor;
• a switch mounted on an exterior top end of said housing and spring biased to an off position for selectively connecting said battery to said motor;
• a recharging unit for recharging said battery;
• cooperating electrical contacts on said recharging unit and on said housing;
• and
• said recharging unit having a top surface provided with a cylindrical recess and said housing having a cylindrical end portion dimensioned for frictional engagement within said recess.
