Patent number: 7530297Abstract: A miter saw has a remotely actuated bevel angle locking system and a bevel angle adjustment assistance system with a remote override actuator so that the user does not need to reach around to the back of the miter saw to adjust the bevel angle. The remote actuator for the bevel angle locking system can be provided on the front of the miter saw's turntable to form a suite of actuators with the miter lock and miter detent override lever. The remote override actuator for the bevel angle adjustment assistance system can be provided on the handle in proximity to the power switch. Also disclosed is a bevel angle adjustment assistance system in which each of the preset bevel angles can be fine tuned simultaneously and which exhibits other advantages.Type: GrantFiled: October 2, 2006Date of Patent: May 12, 2009Assignee: Black & Decker Inc.Inventors: Craig Allen Carroll, Brent Edward Stafford

Patent number: 6569002Abstract: A hand-held oscillating spindle sander is disclosed. The sander includes a pair of toothed pulleys associated with the output shaft. The first pulley is attached to the output shaft for rotation with the output shaft. The second pulley is rotatably disposed on the output shaft for relative rotation with respect to the output shaft. The second pulley includes opposed camming surfaces formed on the inside thereof. A cam follower is attached to and extends from the output shaft so that it is positioned between the opposed camming surfaces. A pair of belts are respectively entrained around the first and second pulleys from a jackshaft rotatably received in the housing. Upon rotation of the belts, both pulleys rotate, but at slightly different speeds. This slight difference in speeds causes the cam follower to move along the opposed camming surfaces to create an oscillation effect for the output shaft.Type: GrantFiled: December 8, 2000Date of Patent: May 27, 2003Assignee: Porter-Cable/DeltaInventors: John Charles Smith, Mark Alan Etter, Brent Edward Stafford, James Timothy Stolzer, Craig Allen Carroll, Thomas O'Neal Walls
