Patent number: 7284761Abstract: A tool bit stop located on an inner surface of a clamping jaw of a drill chuck. The tool bit stop is located a distance from a jaw gripping surface of the clamping jaw. The tool bit stop is adapted to provide a surface to register an end of a tool bit in a consistent location relative to the jaw gripping surface. The tool bit stop is shaped to allow advancement and retraction of the clamping jaws without interference from the tool bit stop.Type: GrantFiled: January 31, 2006Date of Patent: October 23, 2007Assignee: Black & Decker Inc.Inventor: Robert S. Gehret

Patent number: 6994006Abstract: An adjustable rip fence for a machine tool has a fence which is movable with respect to the cutting tool due to a rack and pinion. The rail assembly supporting the fence include a pair of stationary rails which are secure to the machine tool. A movable rail telescopically engages each stationary rail and the movement of each rail is equalized by a set of cables and pulleys.Type: GrantFiled: September 8, 2003Date of Patent: February 7, 2006Assignee: Black & Decker Inc.Inventors: Warren A. Ceroll, Robert S. Gehret, Daniel Puzio, Frederick R. Bean, Michael L. O'Banion, David A. Porter

Patent number: 6820524Abstract: A machine tool has a work table which defines a working surface and has a cutting tool which is attached to and movable with respect to the work table. The position of the cutting tool with respect to the working surface is controlled by a mechanism which elevates the cutting tool with respect to the working surface and angulates the cutting tool with respect to the working surface. The cutting tool is mounted to a support plate which is pivotably attached to the work table. The elevating mechanism includes a threaded rod and a nut which engages a pivoting link. The pivoting link also engages the cutting tool. Rotation of the threaded rod pivots the link which in turn raises and lowers the cutting tool. A spring biases the cutting tool towards its lower position to remove play between the components. The angulating mechanism includes a lever, two cams and a locking rod. Rotation of the lever moves the locking rod longitudinally due to the action between the two cams.Type: GrantFiled: October 12, 1999Date of Patent: November 23, 2004Assignee: Black & Decker Inc.Inventors: Warren A. Ceroll, Frederick R. Bean, Maria I. Kenyon, James R. Parks, Robert S. Gehret, David A. Porter, Michael L. O'Banion, Daniel Puzio, Kevin Brewer

Publication number: 20040154449Abstract: A table saw including a base, a main table supported by the base, first and second rails attached to the table, a sliding table fixedly attached to the rails and sliding along the longitudinal axis of the rails and a cross-cut table slidably movable in a direction perpendicular to the longitudinal axis of the rails. The cross-cut table may be adjusted to ensure movement parallel to a blade protruding from the main table. An improved miter gauge assembly is also disclosed. An improved fence assembly is further disclosed herein. In addition, a table saw having an improved panel and leg construction is disclosed herein.Type: ApplicationFiled: December 11, 2003Publication date: August 12, 2004Inventors: James Parks, Robert S.

Patent number: 6675685Abstract: An adjustable rip fence for a machine tool has a fence which is movable with respect to the cutting tool due to a rack and pinion. The rail assembly supporting the fence include a pair of stationary rails which are secure to the machine tool. A movable rail telescopically engages each stationary rail and the movement of each rail is accomplished by the rotation of a pair of pinion gears each of which engages a respective rack on the movable rails. The simultaneous rotation of the pinion gears is the result of both pinion gears being secured to a common pinion shaft which is rotatably secured to the machine tool. The telescoping nature of the rails allows for adjustment of the fence beyond the working surface of the machine tool.Type: GrantFiled: May 23, 2002Date of Patent: January 13, 2004Assignee: Black & Decker Inc.Inventors: Warren A. Ceroll, Robert S. Gehret, Daniel Puzio, Frederick R. Bean, Michael L. O'Banion, David A. Porter
