Publication number: 20110290376Abstract: A pencil sharpener comprises a housing comprising an aperture to accept a pencil inserted into an interior. A spring is joined to the interior with the spring configured to loop about the inserted pencil. A plate member comprises an aperture to pass the inserted pencil through the plate member. The plate member is configured for linear movement along a length of the inserted pencil. The spring contracts about the inserted pencil and holds the inserted pencil at a fixed position during movement of the plate toward an end of the inserted pencil. A plurality of cutting blade assemblies is joined to the plate to extend along the inserted pencil. Each of the assemblies comprises a cutting blade configured to shave the inserted pencil. A cone structure is configured to guide the cutting blades to shave the inserted pencil to form a point on the end of the inserted pencil.Type: ApplicationFiled: August 7, 2011Publication date: December 1, 2011Inventor: Anwar M. Farooq

Publication number: 20110284129Abstract: A pencil sharpener for sharpening a pencil includes a central gear including an aperture along an axis of the central gear for receiving an end portion of the pencil. A first gear rotates the central gear and a strap joined to the central gear secures the pencil when the central gear is rotated. A shaft is in communication with the first gear where when the central gear is rotated the shaft is rotated. A cutting blade is in communication with the shaft where when the shaft is rotated the cutting blade cuts the end portion of the pencil at an angle to form a point.Type: ApplicationFiled: August 7, 2011Publication date: November 24, 2011Inventor: Anwar M. Farooq

Patent number: 7699082Abstract: An electric multi-pencil sharpener includes an entering pencil vase, a sending mechanism, a hustling mechanism, a sharpening mechanism, and an exit pencil vase. The entering pencil vase includes a pushing mechanism for pushing pencils. The hustling mechanism is for clamping pencils to take the pencils into or out of the sharpening mechanism. The sharpening mechanism is for sharpening the pencils. The exit pencil vase has an exit mechanism. The sending mechanism connects the pushing mechanism, the hustling mechanism, and the exit mechanism, to move the pencils from the pushing mechanism to the hustling mechanism and move the pencils sharpened by the sharpening mechanism to the exit mechanism.Type: GrantFiled: December 18, 2006Date of Patent: April 20, 2010Assignee: Yurisheng Electronic (Shenzhen) Co., LtdInventor: Yuhua Andy Peng

Patent number: 7581573Abstract: An electric pencil sharpener, comprises a base, a powering device, a feeding subassembly, a cutter subassembly and an adjusting subassembly. Two brackets (31, 32) are mounted on the base, standing face to face. Each of the brackets defines two guideways (35) therein. The powering device is attached to the base. The feeding subassembly comprises a feeding gear module and a pair of feeding rollers (23, 24). The feeding rollers are respectively supported in guideways between the brackets. The feeding gear module driven by the powering device makes one of feeding rollers to rotate therein. The adjusting subassembly encompasses the feeding rollers on the bracket. The adjusting subassembly pushes the feeding rollers to move along the guideways. With restriction of the guideways, the distance between the two feeding rollers alters so that pencils with different size can be automatically fed and processed.Type: GrantFiled: November 21, 2006Date of Patent: September 1, 2009Assignee: Ringsun (Shenzhen) Industrial LimitedInventor: Jingyl Hu

Patent number: 7546858Abstract: A pencil sharpener includes a base having a bottom surface adapted for being supported by a horizontal surface. A cutting assembly is mounted to the base and projects upwardly therefrom. A cage is disposed above the base and has an upper portion surrounding the cutting assembly. The upper portion of the cage includes at least one radial chute. An upper cover portion has an opening for insertion of an end of a pencil. A receptacle disposed above the base surrounds the cage, for collecting the shavings from sharpening a pencil.Type: GrantFiled: June 12, 2006Date of Patent: June 16, 2009Assignee: Acme United CorporationInventors: Michael E. Peterson, Stuart David Farnworth, James E. McCay

Patent number: 6886614Abstract: A pencil sharpener having a sharpening sub-assembly for sharpening pencils, and first and second external shells having internal ribs defining surfaces for supporting the sharpening sub-assembly. Components of the sub-assembly are placed into corresponding portions defined by the internal ribs. The ribs ensure proper alignment of the components relative to the shell and each other, e.g. in the x- and y-directions. All components may be placed in the shell in a single direction, e.g. in a single axial direction (the z-direction). The components of the pencil sharpener are mounted in place upon fastening together of the first and second external shells. No internal or additional fasteners are required. The sharpening sub-assembly may include an electric motor, a gear assembly, and a cutter assembly including a cutter gear module having an annular ring gear, acting as a carrier support, and housing a pencil insertion switch and/or a receptacle presence switch.Type: GrantFiled: May 16, 2002Date of Patent: May 3, 2005Assignee: Hunt Holdings, Inc.Inventors: Thomas R. Ricono, Michael Lee Parrish, Sallie S. Daley, Phillip Bruce Daley, Jr.
