Patent number: 11975420Abstract: Method and apparatus for sharpening a cutting edge of a cutting tool, such as a kitchen knife. In some embodiments, an abrasive assembly has a frame, a handle, and a cartridge that supports a plurality of abrasive members each having an associated abrasive surface. A rod affixes the abrasive assembly to a base assembly to facilitate movement of the abrasive assembly along the cutting edge of the tool responsive to engagement, by a user, of the user handle. Each abrasive member is configured to be moved, by the user, with respect to the handle to present each abrasive surface in turn. In some cases, the cartridge is rotatable about a cartridge axis that may be parallel or non-parallel to a central axis of the rod.Type: GrantFiled: December 6, 2022Date of Patent: May 7, 2024Assignee: Darex, LLCInventors: Steven L. Baker, Conner S. MacFarlane, Joseph T. Zachariasen, Daniel T. Dovel, Travis Campbell

Publication number: 20240051088Abstract: Method and apparatus for sharpening a cutting edge of a cutting tool, such as a kitchen knife. A fixture secures opposing sides of a blade of the cutting tool and includes a main body and hinged first and second clamping jaws each having a clamping end adapted to compressingly engage a respective side of the blade. A guide coupled to the main body has converging support surfaces to contactingly engage a back edge (spine) of the blade opposite the cutting edge to center the blade along a central plane of the fixture. A retraction mechanism establishes a clamping force upon each of the respective sides of the blade via the clamping jaws. Further embodiments include a base assembly adapted to receive the fixture, and a swing arm style abrasive assembly to carry out a sharpening operation upon the cutting edge.Type: ApplicationFiled: October 26, 2023Publication date: February 15, 2024Inventors: Steven L.

Patent number: 11806928Abstract: A method for fabricating an article of manufacture includes forming a plurality of layers of the article based on a digital model of the article. Each layer of the plurality of layers may be formed by depositing at least two materials that differ from one another. The at least two materials may be deposited separately or simultaneously. The at least two materials may define separate regions of the layer and, thus, define distinct features of the article, and/or the at least two materials may be mixed or one of the materials may be dispersed throughout the other to define a blended zone in the layer. Blended zones of adjacent layers may be superimposed to define three-dimensional blended zones. A blended zone may be graded to provide transition between separate regions of the article that are formed from two or more different materials. Articles fabricated by such processes are also disclosed.Type: GrantFiled: January 26, 2018Date of Patent: November 7, 2023Assignee: 3D Promed, LLCInventors: Dean E. Cropper, Joseph T. Zachariasen

Patent number: 11478365Abstract: A method for manufacturing a custom wearable and/or implantable medical device, such as an orthosis (e.g., an ankle brace, etc.), a prosthesis or the like, includes use of scanning processes. A digital model of a surface may be applied to a digital device model to define a custom digital device model. The digital model and, thus, the custom digital device model may include one or more standard features. The custom digital device model may be used with an automated manufacturing process to make some or all of the custom wearable and/or implantable medical device. In some embodiments, additive manufacturing processes may be used to form a portion or all of the custom wearable and/or implantable medical device.Type: GrantFiled: June 9, 2020Date of Patent: October 25, 2022Assignee: 3D Patents, LLCInventors: Joseph T.

Patent number: 11364138Abstract: A method for manufacturing a custom wearable medical device, such as an orthosis (e.g., an ankle brace, etc.), includes use of scanning processes. A digital model of a surface may be generated from data corresponding to a body part for which the customer wearable medical device is to be fabricated, and then applied to a digital device model to define a custom digital device model. The digital device model and, thus, the custom digital device model may include one or more standard features. The custom digital device model may be used with an automated manufacturing process to make some or all of the custom wearable medical device. In some embodiments, additive manufacturing processes may be used to form a portion or all of the custom wearable medical device.Type: GrantFiled: November 12, 2019Date of Patent: June 21, 2022Assignee: 3D Patents, LLCInventor: Joseph T.

Publication number: 20220088737Abstract: Apparatus configured to sharpen a blade of a cutting tool. In some embodiments, a sharpener is provided having a housing and a sharpening stage with at least one sharpening element. Each sharpening element is characterized as a plate and has a curvilinearly extending, concave sharpening surface configured to impart a corresponding convex sharpening geometry to a selected side of the blade during a sharpening operation in which a user retracts the blade along a longitudinal drawing axis through the sharpening stage. A pair of intersecting sharpening elements may be provided to form a substantially v-shaped groove for a ripper-type sharpening stage. The sharpening element(s) may be fixed or tiltable with respect to the housing. The sharpening element(s) may further be moveable in a lateral direction to narrow or widen the v-shaped groove and change the convex geometry and edge angle imparted to the blade.Type: ApplicationFiled: December 7, 2021Publication date: March 24, 2022Inventors: Joseph T.

Patent number: 11192217Abstract: Apparatus and method for sharpening a cutting tool, such as but not limited to a knife. A sharpener has a housing with a sharpener stage adapted to facilitate a sharpening operation upon the cutting tool responsive to retraction, by a user, of the cutting tool along a longitudinal drawing axis. A tiltable sharpening mechanism is disposed within the housing adjacent the sharpening stage. The tiltable sharpening mechanism has a central body that is rotatable about a transverse rotational axis nominally orthogonal to the longitudinal drawing axis. The rotatable central body supports at least a first sharpening element. In some cases, the central body supports a pair of intersecting sharpening elements. A biasing member exerts a biasing force to urge the central body of the tiltable sharpening mechanism to a neutral position within the housing. The central body can be locked in neutral, positive rake and negative rake positions.Type: GrantFiled: May 18, 2020Date of Patent: December 7, 2021Inventor: Joseph T. Zachariasen
