Publication number: 20240083003Abstract: A percussion tool includes a housing, a percussion mechanism including a striker supported for reciprocation in the housing along a first axis, and an anti-vibration system for attenuating vibration in a direction of the first axis. The anti-vibration system includes a linkage coupling the percussion mechanism to the housing. The linkage permits relative movement between the housing and the percussion mechanism along the first axis. The anti-vibration system also includes a counterweight supported by the percussion mechanism for relative movement therewith along a second axis that is parallel with the first axis. The counterweight reciprocates out of phase with the striker to attenuate vibration in the direction of the first axis.Type: ApplicationFiled: November 14, 2023Publication date: March 14, 2024Inventors: Matthew S. Zawisza, Andrew D. Van Hoorn, Ethan T. Zimany

Patent number: 11865687Abstract: A method for reducing vibrations in a percussion tool includes activating, using an electronic controller of the percussion tool, the motor of the percussion tool, determining, using the electronic controller, that the percussion tool is in a loaded condition, and operating, using the electronic controller, the motor in accordance with a predetermined profile in response to determining that the percussion tool is in the loaded condition. The method also includes determining, using the electronic controller, that the percussion tool is in a no-load condition and operating, using the electronic controller, the motor with reduced speed in response to determining that the percussion tool is in the no-load condition.Type: GrantFiled: May 4, 2021Date of Patent: January 9, 2024Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Matthew S. Zawisza, Andrew D. Van Hoorn, Ethan T. Zimany

Patent number: 11759935Abstract: A percussion tool comprises a housing and an electric motor positioned within the housing. The percussion tool further comprises a battery pack supported by the housing for providing power to the motor. The battery pack includes a plurality of battery cells having a nominal voltage of up to 120 Volts. The percussion tool further comprises a percussion mechanism driven by the motor and including a striker supported for reciprocation in the housing. The percussion tool has a ratio of impact energy to mass that is greater than or equal to 2.5 Joules/kilogram.Type: GrantFiled: January 26, 2021Date of Patent: September 19, 2023Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Matthew S.

Patent number: 11059155Abstract: A percussion tool comprises a housing, an electric motor positioned within the housing, a percussion mechanism driven by the electric motor and including a striker supported for reciprocation in the housing, a battery pack removably coupled to the housing for providing power to the electric motor when coupled to the housing, and an electronic controller including an electronic processor and a memory. The electronic controller is coupled to the electric motor and configured to activate the motor and determine whether the percussion tool is in a loaded condition. In response to determining that the percussion tool is in the loaded condition, the electronic controller is configured to operate the motor in accordance with a predetermined profile and in response to determining that the percussion tool is in a no load condition, the electronic controller is configured to operate the motor at a no-load speed.Type: GrantFiled: January 25, 2019Date of Patent: July 13, 2021Assignee: Milwaukee Electric Tool CorporationInventors: Matthew S.
