    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.

  • Patent number: 6301791
    Abstract: A sharpener for soft-core pencils includes a core shaper with a shaping edge for shaping the core tip, the edge being positioned in the free space in front of the pencil-guiding channel. This shaping edge is a part of a detachably-secured, separate insert, which limits the free space at the rear housing side, and supports the shaping edge on its side facing the guide channel.

  • Patent number: 6286218
    Abstract: A sharpener contains a housing having a receiving channel for a pencil which is to be sharpened. The sharpener is intended to be seated as a protective cap, when the pencil is not in use, with a clamping fit on the pencil circumference. The clamping connection necessary for this purpose is an external clamping-force producer which can be removed manually from acting on the housing, in particular a cleaning stick, with, for the purpose of providing the clamping force, is for example a pressure-exerting lug in the form of a wedge or with an eccentric.

  • 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: 5894669
    Abstract: A pencil sharpener for a soft core pencil includes a sharpener housing defining a guide channel adapted to receive a front region of the pencil therein and conically tapering in an insertion direction of the pencil, and a free space adjoining the guide channel in the insertion direction and being adapted to receive a core tip of the pencil therein. The sharpener further includes a sharpener blade disposed within the housing and positioned tangentially with respect to the guide channel, and a housing projection disposed in the housing and projecting into the free space and being configured for shaping the core tip of the pencil according to an intended shape. The housing projection comprises a shaving rib having an approximately wedge shaped cross section and projecting from the housing projection in an effective direction essentially tangential to a circumference of the core tip and being configured as a generatrix for the intended shape of the core tip.

    Abstract: A crayon sharpening assembly is disclosed comprising an axially rotating cartridge block (106) having an axial bore (178) for axial receipt of a crayon with a forward end of the crayon positioned within a cutting station (152). A pair of convergent sharpening blades (158, 160) carve a conical nose into the forward crayon end; a secondary horizontal blade (180) engages the forward crayon end and cuts an annular stepped shoulder surrounding the conical nose; and a preparatory vertical blade (188) makes a vertical circumscribing cut through the jacket of the crayon proximate the forward end, whereby restoring the forward crayon end into its manufactured form. A carrying case (12, 14) is provided having a pivotal lid (16), with the sharpener drive assembly (20, 22) built into one end wall. A drawer assembly (100) is removable from the end wall and contains the cartridge block (106) and a housing (102) for collecting shavings generated in the sharpening procedure.
