Patent number: 11897106Abstract: A fastener driver includes a housing having a handle portion. A motor is positioned within the housing. The fastener driver further includes an air compressor including a compressor cylinder and a compressor piston movable within the compressor cylinder in a reciprocating manner to compress air within the compressor cylinder. The fastener driver further includes a drive train converting torque from the motor to a linear force applied to the compressor piston, causing the compressor piston to move in the reciprocating manner. At least a portion of the drive train extends through the handle portion of the housing.Type: GrantFiled: August 17, 2021Date of Patent: February 13, 2024Assignee: MILWAUKEE ELECTRIC TOOL CORPORATIONInventors: Andrew J. Weber, James M. Wentzloff, Nicholas A. Albers, Bradley S. Helm, Troy C. Thorson

Publication number: 20230106037Abstract: A cart for carrying a cut-off saw having a saw blade. The cart includes a frame with upper and lower portions, a wheel arm pivotably coupled to the lower portion about a first axis, and a rear wheel assembly coaxial with the first axis and coupled to the frame and the wheel arm. The cart includes a front wheel coupled to an end of the wheel arm opposite the rear wheel assembly, an adjustment lever pivotably coupled to the upper portion about a second axis, and a link having a first end pivotably coupled to the adjustment lever and spaced from the second axis, and a second end pivotably coupled to the wheel arm between the first axis and the front wheel. Pivoting the adjustment lever about the second axis pivots the wheel arm about the first axis to adjust a vertical position of the front wheel relative to the upper portion.Type: ApplicationFiled: December 8, 2022Publication date: April 6, 2023Inventors: Terry L. Timmons, Dane Laitinen, Mitchell Carlson, Bradley S. Helm, Paul W. Eiche

Publication number: 20220234184Abstract: A power tool including a housing that has a handle portion and a trigger mechanism mounted on the handle portion. The trigger mechanism includes a first trigger for initiating an operation and a second trigger, each of the first and second triggers being movable between a first position and a second position. The second trigger, when in the first position, blocks movement of the first trigger from the first position to the second position.Type: ApplicationFiled: April 14, 2022Publication date: July 28, 2022Inventors: Andrew J. Weber, James M. Wentzloff, Nicholas A. Albers, Bradley S. Helm, Troy C. Thorson
