Abstract:
1. A cosmetic pencil sharpener, comprising: a. a generally hemispherical top surface having a pair of differently sized oppositely disposed openings, the generally hemispherical top surface extending to a circumferential see-through window which in turn extends to a lower sectional wall which in turn extends to an upper casing wall which is connected to a lower casing wall by an interconnecting seam, the lower casing wall extending to a bottom wall which is supported by a multiplicity of feet which thereby provides a stable structure when placed on a horizontal surface; b. a switch support platform supported adjacent the lower portion of the generally hemispherical top surface and supporting a switch assembly including a start switch connected to an open switch connector spring which is adjacent to a transition connector spring which in turn is connected to a safety spring switch, the switch support platform including means to permit the generally hemispherical top surface to rotate about the switch support platform and to be locked into a certain position, the switch support platform further supporting a source of illumination which shines through said circumferential see-through window when illuminated; c. an intermediate platform positioned beneath said switch support platform and supporting an electric motor having a drive gear; d. a gear assembly platform positioned beneath said intermediate platform and including a gear assembly which intermeshes with the drive gear of said electric motor and a sharpener gear assembly, the sharpener gear assembly including a transfer engaging block; e. a sharpener body comprising a top opening, a central chamber, a floor and a bottom, the floor having an opening extending into the central chamber, the bottom having an opening which receives the transfer engaging block of the sharpener gear assembly, a left wall to one side of the central chamber and aligned at a given angle to the central chamber and supporting a razor also aligned at the given angle to the central chamber, and a right wall on the opposite side of the central chamber and aligned at the same given angle to the central chamber but the angle being oriented in the opposite direction, to thereby form a tight fit central chamber within the sharpener body; f. the sharpener body rotatably positioned between the switch support platform and the intermediate platform and receiving the transfer engaging block of the sharpener gear assembly, the sharpener gear assembly further including a sharpener indicator rod extending vertically through the opening in the floor of the sharpener body and also through the transfer engaging block, and a plunger aligned with the sharpener indicator rod and extending downward from the sharpener gear assembly, the plunger positioned above a light indicator switch supported on said gear assembly platform; g. the switch support platform having an opening which is aligned with the top opening in the sharpener body, the intermediate platform having an opening which is aligned with the opening in the floor of the sharpener body, and the engaging means of the sharpener gear assembly connected to said sharpener body and the sharpener indicating rod extending through the opening in the floor of the sharpener body to a location just below the razor and the oppositely disposed right wall; h. a battery pack having at least one battery positioned on the bottom wall and electrically connected so that the positive terminal of the battery is connected to the start switch which in turn is connected to the positive side of the electric motor, the negative terminal of the battery connected to the negative side of the electric motor and also connected to the negative side of the source of illumination, the positive terminal of the battery connected to the light indicator switch; and i. the generally hemispherical top surface rotated so that one of its openings is aligned with the opening in the switch support platform and a portion of the start switch extending into the opening in the switch support platform so that when a cosmetic pencil is inserted through an opening in the top surface, the cosmetic pencil causes the start switch to move so that the open connector spring comes in contact with the transition connector spring to thereby close the circuit for the battery and electric motor, the tip portion of the cosmetic pencil enters into the central chamber of the sharpener body where it is positioned between the razor and the right wall, the sharpener gear assembly is caused to rotate in the counterclockwise direction which in turn causes the sharpener body to rotate in the counterclockwise direction so that the razor sharpens the tip of the cosmetic pencil by rotating in the counterclockwise direction, the power of the battery being sufficient to enable the sharpening process to take place in from one to three seconds, and when the sharpening is completed the top of the cosmetic pencil presses against the sharpener indicator rod which in turn causes the source of illumination to shine through the window to advise that the sharpening process has been completed.
