Patent number: 11926028Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, a driver blade attached to the piston and movable therewith between a ready position and a driven position, a lifter to move the driver blade from the driven position to the ready position, and a transmission including an output shaft operatively coupled to the lifter to provide torque to the lifter. The fastener driver also includes an input to provide torque to the transmission and a clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft and the lifter. In response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the input is diverted from the output shaft via the clutch.Type: GrantFiled: July 22, 2021Date of Patent: March 12, 2024Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Andrew R. Wyler, Nathan T. Armstrong, Jason D. Thurner, Troy C. Thorson, John S. Scott, Jeremy R. Ebner, Daniel R. Garces, Ryan Allen Dedrickson, Luke J. Skinner, Benjamin R. Suhr

Publication number: 20230234205Abstract: Kickback control methods for power tools. One power tool includes a movement sensor configured to measure an angular velocity of the housing of the power tool about the rotational axis. The power tool includes an electronic processor coupled to the switching network and the movement sensor and configured to implement kickback control of the power tool. To implement the kickback control, the electronic processor is configured to control the switching network to drive the brushless DC motor, receive measurements of the angular velocity of the housing of the power tool from the movement sensor, determine that a plurality of the measurements of the angular velocity of the housing of the power tool exceed a rotation speed threshold, and control the switching network to cease driving of the brushless DC motor in response to determining that the plurality of the measurements of the angular velocity exceed the rotation speed threshold.Type: ApplicationFiled: April 4, 2023Publication date: July 27, 2023Inventors: Jonathan E. Abbott, Timothy R. Obermann, John S. Dey, IV, Benjamin R. Suhr, Richard A. Ryer, Maxwell L. Merget, Douglas R. Fieldbinder
