Patent number: 11945079Abstract: A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.Type: GrantFiled: March 29, 2021Date of Patent: April 2, 2024Assignee: Milwaukee Electric Tool CorporationInventors: Collin J. Nelson, Steven W. Hyma, Grant T. Squiers, James A. Cemke, Jr., Abhijeet A. Khangar

Publication number: 20240102783Abstract: A tool, such as a tape measure, including a spring-based retraction system is shown. Various spring-based retraction system embodiments are configured to decrease the size occupied by the spring within the tape measure housing, which consequently reduces tape measure housing size providing a more compact tape measure. Various spring-based retraction system embodiments are configured to control retraction of the tape measure in a manner that reduces whip or otherwise controls tape blade retraction. Some retraction system embodiments utilize a reduction gear train, and others utilize a compression spring and a transmission system that converts rotational movement of the tape reel to axial movement, which compresses the spring.Type: ApplicationFiled: December 5, 2023Publication date: March 28, 2024Inventors: Collin J. Nelson, David Andrew Wortelboer, Kyle C. Anderson, Abhijeet A. Khangar, Jonathan F. Vitas

Publication number: 20230017379Abstract: A workpiece engaging surface that includes a pattern of laser-etched channels and related method of manufacturing is provided. The laser-etched pattern on the surface of the workpiece engaging surface is formed by multiple groupings of closely spaced channels that generate serrated teeth in the surface of the tip. Each grouping of channels is formed by passing a laser over a first location a first number of passes to form a first channel, passing a laser over a second location, spaced apart from the first location by a channel spacing distance, a second number of passes to form a second channel, and passing a laser over a third location, spaced apart from the second location by the channel spacing distance, a third number of passes to form a third channel. In some embodiments the first, second, and third number of passes are the same.Type: ApplicationFiled: September 16, 2022Publication date: January 19, 2023Inventors: Collin J. Nelson, Andrew M.
