Patent number: 9464893Abstract: A power tool includes a housing, an output shaft having a tool axis, and a motion sensor that senses motion of the tool housing. A control circuit receives an input signal from the motion sensor, to make a first determination, based on the input signal, whether the tool is being operated in a horizontal mode or a vertical mode. The control circuit makes a second determination, based on the input signal, whether the tool axis is substantially level when the tool is being operated in the horizontal mode or the tool axis is substantially plumb when the tool is being operated in the vertical mode. An indicator receives an output signal from the control circuit that causes the indicator to indicate whether the tool axis is level when being operated in the horizontal mode or plumb when being operated in the vertical mode.Type: GrantFiled: February 28, 2013Date of Patent: October 11, 2016Assignee: Black & Decker Inc.Inventors: John C. Vanko, Craig A. Schell, Robert S. Gehret, Michael K. Forster, Tal Gottesman, Sankarshan Murthy, Daniel Puzio, Joerg Zellerhoff, Robert A. Usselman, Scott J. Eshleman, Joao Norona

Publication number: 20160263669Abstract: A chop saw includes a base assembly and a saw assembly pivotally attached to the base assembly. The base assembly has a workpiece-supporting plane. The saw assembly has a blade and a motor driving the blade. A hinged connection between the base assembly and a saw assembly allows a user to rotate the saw assembly from a position where the plane of the blade extends through the workpiece-supporting plane to a position where the plane of the blade does not extend through the workpiece-supporting plane. In such position, the plane of blade may be substantially parallel to the workpiece-supporting plane.Type: ApplicationFiled: February 3, 2016Publication date: September 15, 2016Inventors: Robert S.

Publication number: 20160228953Abstract: A bit retaining system for a rotary tool or device such as a router is disclosed. The bit retaining system may include a collet assembly and a control assembly. The collet assembly may include a spindle, a collet adapted to receive the bit, and a collet nut. The collet assembly may further include a collet gear mounted on the collet nut and/or a spindle gear mounted on the spindle. The control assembly selectively engages the collet assembly to drive the collet nut and/or secure the spindle in a fixed position, preventing its rotation. In operation, a hand tool is utilized to engage the control assembly. This configuration enables a user to capture and release the rotary tool bit using one hand.Type: ApplicationFiled: December 28, 2015Publication date: August 11, 2016Inventors: Warren A.
