Adjustable cosmetic brush system

An adjustable cosmetic brush system (10) comprising, in combination:

• a handle shaft (14) with an upper end and a lower end, a cylindrical collar (16) extending upwardly from the upper end of the handle shaft, the cylindrical collar having two vertical channels (20) diametrically opposed to each other, the cylindrical collar having an open top (26) with a cylindrical configuration;
• a brush head (36) formed of a plurality of elongated bristle fibers (34), the bristle fibers having lower ends (104) secured in the open top of the cylindrical collar, the bristle fibers having free upper ends (106), the bristle fibers having intermediate extents (98);
• a ferrule assembly (22) axially reciprocable upon the cylindrical collar (16) between an operative upper position (V1) and a cleaning lower position (V2), the ferrule assembly formed of an inner coupler (50) and an outer coupler (48), the inner coupler being in sliding contact with the cylindrical collar, the outer coupler being in contact with the inner coupler for sliding therewith, the ferrule assembly having a lower end (24) and an upper end (26), the upper end being of a reduced circumference for sliding contact with the intermediate extents of the bristle fibers whereby when the lower end of the ferrule assembly is adjacent to the lower end of the cylindrical collar the bristle fibers are loosely extended for cleaning, and whereby when the lower end of the ferrule assembly is adjacent to the upper end of the cylindrical collar the bristle fibers are held tightly for application of cosmetics;
• the outer coupler being formed with circumferential gripping projections (30);
• the inner coupler including interiorly extending tabs (78) reciprocable within the vertical channels in the cylindrical collar;
• the inner coupler and the outer coupler having oval shaped upper openings (80) (82);
• the inner coupler and the outer coupler laterally rotating with the oval shaped upper openings that hold the elongated bristles fibers when the openings are aligned (L2) and then adjusted laterally reducing an uppermost opening diameter (84) of the ferrule assembly which thereby adjusts the formed brush head application shape;
• and
• a vibration assembly positioned within the handle, the vibration assembly including a rotatable counterbalance weight (228), a motor (224) for rotating the counterbalance weight, and a source of electrical potential (220) for the motor, the vibration assembly adapted to vibrate the bristle fibers to increase the efficiency of the brush system during cosmetic product application.
