Publication number: 20230256640Abstract: Control systems to control the operation of a power tool are disclosed. The disclosed control systems are particularly, but not exclusively, applicable to power tools with active injury mitigation technology, and to table saws with active injury mitigation technology, such as jobsite and benchtop table saws. The improved systems, for example, control the supply of power to a motor, enhance reliability, provide redundant safety features, and help to prevent the motor from starting unexpectedly.Type: ApplicationFiled: July 13, 2021Publication date: August 17, 2023Applicant: SawStop Holding LLCInventors: Louis R. Slamka, Jeremy C. Espinosa, Tyler S. Howell, Paul H. Stasiewicz, Brian M. Unger

Publication number: 20220176540Abstract: A folding stand with a pivoting securing mechanism to secure an object to the stand is disclosed. The stand may include two rails in the same horizontal plane and a securing mechanism that pivots about an axis which is perpendicular to that horizontal plane. The securing mechanism may be positionable in a locked and an unlocked position. The securing mechanism may include one or more arms that extends over a portion of the object in the locked position.Type: ApplicationFiled: December 17, 2021Publication date: June 9, 2022Applicant: SawStop Holding LLCInventors: Benjamin J. Stockwell, Curt M. Kemper, Paul H. Stasiewicz

Patent number: 11104028Abstract: Fences for use in table saws are disclosed. One embodiment may include an actuator, handle or lever to lock and unlock the fence from the table, where the actuator, handle or lever is positioned substantially above the tabletop and substantially within the perimeter of the table (including any rail associated with the table). Another embodiment may include an actuator, handle or lever to lock and unlock the fence from the table, where the actuator, handle or lever is positioned along a top surface of the fence and configured so that the fence unclamps from the saw when the actuator, handle or lever is pressed. The fence may be configured to include a material support shelf that is selectably extendable and retractable.Type: GrantFiled: August 18, 2015Date of Patent: August 31, 2021Assignee: SawStop Holding LLCInventors: Jeremy J. Burke, John P. Nenadic, Stephen F. Gass, J. David Fulmer, Paul H. Stasiewicz

Publication number: 20200376574Abstract: Table saws and features for table saws are disclosed. Some of the disclosed features are particularly relevant to portable table saws such as jobsite and bench-top table saws. Disclosed features include, but are not limited to, extendable rails, mechanisms to lock rails in position, drawers, compartments and components to store table saw accessories, switch boxes, dust collection systems, table saw housings, tables, and handles.Type: ApplicationFiled: June 22, 2020Publication date: December 3, 2020Applicant: SAWSTOP HOLDING LLCInventors: J.

Patent number: 10737338Abstract: A dust collection system designed for a table saw is disclosed. The dust collection system includes a dust shroud and dust shield to channel dust generated by a blade as it cuts wood or other material. The dust shroud includes fins and walls to “peel” dust and air off a spinning blade and direct the dust and air downward. The dust shroud encloses the lower front portion of a blade. An insert with a channel into which a dust shield can extend is disclosed.Type: GrantFiled: December 4, 2013Date of Patent: August 11, 2020Assignee: SawStop Holding LLCInventors: Paul H. Stasiewicz, John P. Nenadic

Patent number: 10710269Abstract: Blade guards for power tools such as table saws are disclosed. The blade guard may include a shroud that pivots up and down to allow a workpiece to move past the guard, a dust collection channel, and a pivot joint which maintains the dust collection channel in an operable condition as the shroud pivots up or down. The guard may also include a wood stop and anti-kickback pawls. The blade guard may be part of a dust collection system and may be connected to a vacuum system by a conduit such as a flexible hose.Type: GrantFiled: March 6, 2017Date of Patent: July 14, 2020Assignee: SawStop Holding LLCInventors: Hollan A. Tsuda, John P. Nenadic, Paul H. Stasiewicz

Patent number: 10562114Abstract: Table saws and table saws designed to incorporate safety systems are disclosed. The table saws may include vertical slide elevation mechanisms positioned toward the rear of the saw and constructed so that an arbor block and blade can retract when a safety system detects an unsafe condition. Other table saw parts and components are also disclosed.Type: GrantFiled: May 25, 2018Date of Patent: February 18, 2020Assignee: SawStop Holding LLCInventors: Stephen F. Gass, J. David Fulmer, William L. Emery, Paul H. Stasiewicz

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
