| 20090071018 | METHOD OF SHARPENING A CARPENTER'S PENCIL - A carpenter's pencil sharpener is designed for cutting a point on a carpenter's pencil that defines a longitudinal axis and has a maximum width or dimension (MD) perpendicular to the longitudinal axis. The sharpener has a contouring portion defining a rotational axis, a pencil point contour surface and a blade. The sharpener also has a centering portion at least rotationally fixed to the contouring portion. The centering portion has a non-rotating, cylindrical, inner surface and an outer end defining an aperture for receiving the carpenter's pencil. The cylindrical surface has an inner diameter (ID) dimensioned to fit the maximum dimension (MD) of the carpenter's pencil, and is large enough to permit rotation of the carpenter's pencil within the cylindrical surface. The centering portion also has a length (L) generally parallel to the rotational axis and measured from the contouring portion to the outer end for maintaining the carpenter's pencil parallel to the axis. With this configuration, radial motion of the carpenter's pencil relative to the rotational axis is limited when the carpenter's pencil is rotated within the inner surface. | 03-19-2009 |

| 20080244917 | Cosmetic Pencil Sharpener - A sharpener, particularly a cosmetic pencil sharpener, contains a sleeve-like sharpener housing whose inside diameter for rotationally guiding the pencil to be sharpened is dimensioned so that it is somewhat larger than the outside diameter and whose inside length is dimensioned in such a manner that it enables a pencil end section to be conically sharpened by a sharpening blade diagonally projecting into the inside cross-section of the sharpener housing. Another sleeve-like housing section is situated at the end of the sharpener housing opposite the insertion end and is separated from the sharpener housing by a partition The inner area of the second housing section is provided in the form of a tight blind bore with an inside diameter approximately corresponding to the outside diameter of the pencil to be sharpened and, in the form of a pencil protector, and can be slid onto the pencil with a press fit. | 10-09-2008 |
| 20090126207 | PENCIL SHARPENER CAP - 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. | 05-21-2009 |
| 20110179654 | SHAVING TRAY FOR PENCIL SHARPENER - A pencil sharpener includes a base containing a sharpening mechanism, and a shaving tray coupled to the base and movable between an installed position and an uninstalled position relative to the base. The shaving tray defines a chamber configured to receive and hold shavings produced during a sharpening operation. The shaving tray includes a body, an aperture in the body configured to receive shavings for passage into the chamber, a movable member configured to selectively cover the aperture to inhibit shavings from leaving the chamber through the aperture, and a biasing member coupled to the body and to the movable member to bias the movable member into a closed position covering the aperture. | 07-28-2011 |
| 20110179655 | SLIP-ON PENCIL SHARPENER SYSTEM - A pencil sharpener removably couplable to a non-mechanical pencil including: a body comprising an external volume having a conically-shaped inner volume; a steel blade cutter that is removable and replaceable and is received in a recessed portion within an outer face side of the body; a biasing clip attacher that permits removable attachment of the pencil sharpener onto objects including a clothing pocket, belt, or bookmark; a light to provide illumination, and a friction fit cylindrical stabilizer having a biasing slit and a closed end for receiving a proximate end of the non-mechanical pencil. Further, the body has an outer face side of the body with a hand-conforming contour providing an increased-efficiency shave-removing surface within the body to permit insertion of a distal end of the non-mechanical pencil. | 07-28-2011 |
| 20130174429 | Dual Drive Pencil Sharpener - A portable pencil sharpener is capable of being manually operable or operable to be driven by a remote torque driver. The pencil sharpener is capable of sharpening either a carpenter's pencil or a Number 2 pencil. Pencil shavings are retained in a compact housing and removed through a retractable panel. | 07-11-2013 |

| 20080282559 | PENCIL SHARPENER - A pencil sharpener includes a sharpener body, a blade mounting member which is fitted to a distal surrounding wall of the sharpener body and which has a seat end wall with a slot to form an insertion path, a blade which is disposed in the slot, a tubular grip member which is fitted in an insertion hole and which is movable between non-working and working positions to be remote from and close to the seat end wall, respectively. The grip member has an inner peripheral grip surface which defines a passage to be communicated with the slot and which is brought into engagement with a lead-side end of a pencil barrel to permit a lead of the pencil to be placed in the insertion path once the grip member is displaced to the working position. A biasing member is disposed to bias the grip member to the non-working position. | 11-20-2008 |
| 20110099820 | PENCIL SHARPENER - A pencil sharpener includes a main body, a first gear, a second gear, a turning member, a top lid and an elastic piece. The first gear has a central hole for insertion of a pencil. The first gear engages with the second gear. The second gear has at least one waved portion thereon. The position of the turning member is changed by movement of the waved portion to open and close the top lid with respect to the main body, providing visual and sound effects. The elastic piece is located beside the first gear or the second gear. The elastic piece can sound along with rotation of the gears. The pencil sharpener of the present invention has visual and sound effects to attract consumers. | 05-05-2011 |
| 20110258863 | Pencil Sharpener - A pencil-sharpener tool for carpenter pencils includes a housing, a pencil-tip-insertion hole, and a hex-bit-drive hole. The pencil-tip-insertion hole may configured in to receive a portion of a carpenter pencil. The hex-bit-drive hole may extend at least partially through the housing opposite the pencil-tip-insertion hole. The hex-bit-drive hole may also be in axial alignment with the pencil-tip-insertion hole and the central axis of the housing. The housing, the pencil-tip insertion hole, and the hex-bit-drive hole may be in fixed relation to each other, and may move in unison when the hex bit is inserted inside the hex-bit-drive hole and rotates clockwise or counterclockwise. | 10-27-2011 |
| 20120017451 | SHARPENER, ESPECIALLY FOR A COSMETIC OR PHARMACEUTICAL PENCIL - 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. | 01-26-2012 |
