Patent number: 11229914Abstract: The present disclosure is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for separating at least a sheet from a stack in a tray. The separation mechanism can be activated by rotation of the cutter elements. In one embodiment, the separation mechanism is provided in the form of a helical mechanism configured for insertion into the stack and to receive separated sheets from the stack in between its space(s) as it is rotated. The separated sheets can fall via gravity into the shredder mechanism. Optionally, a paper feed mechanism can feed separated paper to the cutter elements. The tray can include an edge to assist in directing separated paper towards the cutter elements. One or more staple picking support mechanisms can also be provided to assist in separating sheets from a stapled set of pages.Type: GrantFiled: August 7, 2019Date of Patent: January 25, 2022Assignee: FELLOWES, INC.Inventors: Steven Carson, Tai Hoon K. Matlin, Shawn Michael Applegate, Dennis William Gruber, Dipan Pravin Surati

Patent number: 9669411Abstract: A shredder has cutter elements for destroying articles (paper) and a feed mechanism for advancing paper from a stack in a tray into cutters for shredding. The feed mechanism has a feed member provided adjacent to the tray with an elastic arm for engaging and disengaging the stack. The feed member rotates in a feeding direction about an axle, with the elastic arm elastically deforming to apply pressure to feed paper atop the stack to the cutters. The elastic arm can include a protruding tip that is inserted into the stack. The tray includes a curved feed bed to assist in feeding paper into the cutters and deforming the elastic arm. A pivot arm can also move the feed member relative to the tray (e.g., vertically). A disengagement mechanism can hold the feed mechanism in an inoperable feeding position when a drawer or tray is moved into an open position.Type: GrantFiled: September 30, 2013Date of Patent: June 6, 2017Assignee: FELLOWES, INC.Inventors: Tai Hoon K.

Patent number: 9346059Abstract: A shredder includes a shredding mechanism and a vibration sensor configured to detect vibrations generated by the shredding mechanism. The shredder includes a controller configured to regulate operation of the shredder's motor in response to the detected vibrations. The controller may regulate operation of the shredder so as to keep the detected vibrations below a predetermined vibration level during operation of the shredder. The controller may modify operation of the shredder (e.g., turn the shredder off, conduct an autocorrect sequence, increase or decrease the shredder's speed, display an error message) in response to the detected vibrations having a predetermined characteristic (e.g., frequency and/or amplitude within a predetermined range, a characteristic that indicates a material/paper jam or misfeed).Type: GrantFiled: December 4, 2014Date of Patent: May 24, 2016Assignee: FELLOWES, INC.Inventors: Michael Dale Jensen, Dennis William Gruber, Daniel Namie, Dipan Surati
