  • Patent number: 8881410
    Abstract: A sharpener for sharpening a pencil, in particular a cosmetic pencil, is especially suitable, when used correctly, for producing a particularly uniform outer jacket edge in the region of the pencil tip. The sharpener includes a sharpener body, in which a pencil guide channel is provided. The pencil guide channel has a circular cone-shaped channel section and opens out in a pencil inlet opening on the outer side of the sharpener body. A paring blade is positioned tangentially to the lateral surface of the channel section. The paring blade serves to pare off a pencil tip, which includes a front lead section and a rear outer jacket section. A shaping tool cuts a shoulder into the pencil tip, the shoulder being set back in relation to a circular cone-shaped enveloping surface of the pencil tip. The shaping tool is arranged relative to the pencil guide channel to insert the shoulder into the transition between the lead section and the outer jacket section of the pencil tip.

    Abstract: A pencil sharpener includes a housing having an inner cavity for receiving at least a portion of a pencil therein. The pencil includes a center portion and an outer portion generally coaxial with the center portion. A sharpener is longitudinally slidable within the inner cavity. A mechanism provides a linear force to the sharpener to move the sharpener between open and closed ends of the housing. The linear force mechanism is disposed between the sharpener and the closed end of the housing. The engagement of the pencil and housing during sharpening of the pencil produces shavings from the center and outer portions of the pencil that are retained within the inner cavity. A combined longitudinal length of the housing and pencil in an engaged configuration remains approximately constant as the pencil decreases in length from use and/or sharpening.

    Abstract: An improved hand tool for trimming and deburring the edges of objects made of various materials is provided with an elongated body member having a longitudinal channel formed therein for receiving the edge of the object to be trimmed. An elongated opening passes through the body member, from its lower surface into open communication with the longitudinal channel. An elongated blade is secured within the body member and positioned to selectively adjustably pass through the opening into the longitudinal channel to engage the edge being passed through the longitudinal channel. An adjustment assembly allows for incremental and consistent adjustment of the blade's cutting depth. Storage compartments are provided within the body member for conveniently and safely storing replacement blades.

    Abstract: There is provided herein a power drive adapter for a pencil sharpener or other manually rotatable tool which affixes a shank to the tool. In one embodiment this affixation includes a peripheral edge positioned on the tool and a shank attached to that edge. In another embodiment a holder member having a yolk of dual prongs is fitted with a power drive compatible shank. The inner surface of the prongs has grooves for engaging protruding edges positioned on the tool. As a result, the holder member securely grasps the manually rotatable tool (pencil sharpener) at one extremity and presents at its other extremity a shank for insertion into the chuck of the chosen electric drive.

  • Patent number: 6309088
    Abstract: The invention discloses a combined pencil sharpener and an ink stamp being able to give off light. The invention includes a pencil sharpener and a stamp which are slidably engaged together. When a pencil is inserted into an opening of the pencil sharpener, it will move the sharpener towards the stamp and then conduct a circuit contained in a housing of the stamp to allow an LED to give off light. The invention will not only increase the attractiveness of the sharpener but also be very helpful to teach a young user to sharpen a pencil.

  • Patent number: 6279237
    Abstract: A sharpener (1) contains a housing (5) with a blade (13) which is screwed on said housing and forms a tangent to a hollow-conical region (6b) of a guide channel (6) for the pencil (2), said hollow-conical region adjoining a hollow-cylindrical region (6a), a bending edge (19) being formed in the process. In the fixed position, the blade (13) is subjected to bending stressing in that, with the outer end (14) of the blade (13) being guided beneath the housing-side protrusion (16), the inner end (18) of said blade is fixed on the housing (5), the blade (13) being bent about the bending edge (19) in the process. This thus provides particularly secure and space-saving blade fixing (12) at both ends.

  • Patent number: 6249981
    Abstract: An improved structure of a sharpener comprising an ornamental seat, a light-emitting body, a fixing seat module, a spring, a conductive cap, a push rod, a main body containing a sharpening means, and a bottom cap, wherein the fixing seat module can be replaced by a circuit board, a musical disc and a sound mask. When a pencil is inserted into a sharpening aperture provided on the main body, the push rod is elevated and the light-emitting body at the top end of the fixing seat module is lighted. When the circuit board is used to replace the fixing seat module and a pencil is inserted into the sharpening aperture, the light-emitting body on the circuit board is lighted and music is produced. If the pencil is withdrawn from the main body, there is no electrical current provided to the circuit board, and thus, the music and the light are turned off.

  • Patent number: 6237656
    Abstract: A pencil sharpener bit for use in sharpening pencils utilizing a portable electric drill, any motorized hand tool supporting the use of a chuck assembly or any hand held tool accepting tips with hexagonal ends is disclosed. The sharpener assembly rotates in a standard clockwise motion while the pencil is held by hand in a stationary position. The sharpener frame is of sufficient size to completely encase the point cutting assembly. The said point cutting assemble is set at a sufficient depth to remove successive layers of a pencil resulting in a conically shaped point. The sharpening assembly removes only enough material to bring the pencil to a sufficient point of sharpness. A slot is provided for material dispersal and collection in an outer cover. The housing of the sharpener is cylindrical in shape and is attached to a hexagonally shaped shaft bit intended for use with any standard chuck with three jaws or teeth.
