Publication number: 20210316394Abstract: A laser cutter and safe power system therefor are disclosed. The power system of the laser cutter includes a resistive device arranged in a return line and configured to prevent anomalous tripping of a GFCI device by significantly minimizing electrical noise transmitted through the GFCI device when the laser cutter is operated in certain modes, such as a pulsing mode. The resistive device includes end caps that form a shroud around the connection between a return wire and the contact at each end of the resistive device. A main control board for a high voltage subsystem of the power system includes two isolated and independent enable signals, which are provided to different controllers on the main control board such that the different controllers can independently and redundantly respond to an unsafe condition.Type: ApplicationFiled: August 23, 2019Publication date: October 14, 2021Inventors: Gregory A. Herman, James Randall Cooper, Walter Bernardi, Bradley D. Padget, Richard M. Ness, Emory Wheeler

Patent number: 10549435Abstract: An accessory tool for an oscillating tool includes a first metal plate and a second metal plate fixed together to form a body having a first end portion formed by the first metal plate and a second end portion formed by the second metal plate. The first end portion defines a linear cutting edge, and the second end portion defines a drive interface for mounting the accessory tool onto a tool holder of an oscillating tool. The second metal plate includes an overlapping portion that overlaps a portion of the first metal plate. At least one of a first lateral portion and a second lateral portion of a leading edge of the overlapping portion is spaced farther away from the cutting edge than a central portion of the leading edge of the overlapping portion.Type: GrantFiled: December 31, 2015Date of Patent: February 4, 2020Assignees: Robert Bosch Tool Corporation, Robert Bosch GmbHInventor: Bradley D Padget

Patent number: 10137548Abstract: A foot attachment for a pneumatic rotary tool is configured to be attached to a nose portion of the housing of the tool. The rotary tool includes a housing that defines an air flow channel. A nose portion of the housing defines an air flow inlet for the air flow channel. The foot attachment includes a shroud portion that extends from the nose portion of the housing and surrounds a working space in front of the nose portion of the housing. The shroud portion defines at least one tangential opening that directs air flow into the shroud portion along a tangent such that a vortex is generated within the working space.Type: GrantFiled: December 30, 2015Date of Patent: November 27, 2018Assignees: Robert Bosch Tool Corporation, Robert Bosch GmbHInventors: Bradley D Padget, Daniel Blythe, Jr., Kevin Wasielewski
