Patent number: 11548083Abstract: Inserts for use in table saws are disclosed. One embodiment may include a mechanism to lock mechanically and affirmatively the insert in a blade opening in a table saw. The mechanism is designed so that a user can install and remove the insert without tools. The mechanism also can be designed so that the front of the insert pops up above the table when released from its locked position. The mechanism can be further designed so that the insert can be unlocked or released by a user pressing a button or tab.Type: GrantFiled: March 19, 2018Date of Patent: January 10, 2023Assignee: SawStop Holding LLCInventors: Stephen F. Gass, James F. W. Wright

Patent number: 11273504Abstract: Inserts for table saws are disclosed. The table inserts are equipped with a toolless locking mechanism that mechanically holds the insert in place and which allows for the installation and removal of the insert without the use of tools. The locking mechanism is easy to lock and unlock and yet robust enough to hold a zero-clearance insert in place.Type: GrantFiled: March 16, 2020Date of Patent: March 15, 2022Assignee: SawStop, Holding LLCInventors: John P. Nenadic, James F. W. Wright, Stephen F. Gass

Patent number: 11027452Abstract: Blade guards for table saws are disclosed. The blade guards can be used in a configuration where the guard holds a work piece against a work surface. This may be thought of as blade guards with hold-down capability. The blade guards also include splitters and anti-kickback assemblies. The anti-kickback assemblies include anti-kickback pawls that can be in an operable configuration or a disabled configuration.Type: GrantFiled: August 6, 2018Date of Patent: June 8, 2021Assignee: SawStop Holding LLCInventors: Stephen F. Gass, James F. W. Wright

Patent number: 10875210Abstract: Blade tilt mechanisms for table saws are disclosed. The disclosed tilt mechanisms provide easy and intuitive operation. They also provide auto-locking so that a user simply releases a component to lock the blade at a specific angle. The tilt mechanisms also provide defined incremental steps for the tilt of the blade and the steps are typically spaced at 1-degree intervals.Type: GrantFiled: August 19, 2019Date of Patent: December 29, 2020Assignee: SawStop Holding LLCInventors: Stephen F. Gass, J. David Fulmer, James F. W. Wright

Patent number: 10537949Abstract: Elevation mechanisms for table saws and anti-backdrive mechanisms for use in elevation mechanisms for table saws are disclosed. The anti-backdrive mechanisms typically include three sub-assemblies: an input assembly, an output assembly, and a fixed assembly. The anti-backdrive mechanisms prevent a torque related to the output assembly from changing the blade elevation. For example, the weight of the blade and the structure supporting the blade is prevented from backdriving the elevation mechanism and allowing the blade to drop.Type: GrantFiled: March 5, 2018Date of Patent: January 21, 2020Assignee: SawStop Holding LLCInventors: Stephen F. Gass, James F. W. Wright, J. David Fulmer, Jeffrey D. Weston, Steven D. McDaniel, D. Tate Fanning, Paul H. Stasiewicz

Patent number: 10118308Abstract: Mounting systems to secure and index riving knives and spreaders in table saws are disclosed. One embodiment may include three mounts or screws attached to an elevation carriage. A clamp plate fits over the heads of the mounts and a handle pivots to move the clamp plate against flanges on the heads of the mounts to clamp a riving knife or spreader in place.Type: GrantFiled: October 17, 2014Date of Patent: November 6, 2018Assignee: SawStop Holding LLCInventors: Stephen F.
