Publication number: 20080041211Abstract: The present invention is directed toward a system for forming miter joints including a miter saw and an angle gauge. The miter saw includes a platform with a kerf slot and a pair of arcuate slots. Each arcuate slot includes an associated rail located on the underside of the platform. A fence is coupled to each of the rails such that the fence may be pivoted with respect to the platform. The angle measurement tool is a one-handed tool including spring loaded paddles that measure the angle between intersecting surfaces. The angle measurement tool connects to the miter saw to permit the transfer of the measured angle to the fences.Type: ApplicationFiled: July 17, 2007Publication date: February 21, 2008Applicant: Black & DeckerInventors: Louis Gibbons, Gregory S.

Patent number: 7232120Abstract: A workbench has at least one drive member to clamp table members against one another. The drive member has a receiving tube and a crank tube. The receiving tube and crank tube are coupled with respect to one another for telescoping movement. One of the tubes has a threaded member and the other tube has a thread engaging member. A mechanism engages and disengages the thread engaging member into the threaded member such that in an engaged position, the crank tube can be rotated in the receiving tube for screw type movement. In a disengaged position, the crank tube is freely slidable for sliding movement in the receiving tube.Type: GrantFiled: July 19, 2005Date of Patent: June 19, 2007Assignee: Black & Decker Inc.Inventors: David C.

Patent number: 6241260Abstract: A drill has a chuck with a body member and a bore to receive a cutting tool. A plurality of jaw members are coupled with the body to retain the cutting tool in the bore. A mechanism to secure the cutting tool in the jaws is coupled with the body. The mechanism applies a biasing force on the jaw members which enables the jaw members to slide on the body between a locked position securing the cutting tool in the jaw members and an unlocked position which enables egress and ingress of the cutting tool into and out of the jaw members.Type: GrantFiled: August 17, 1999Date of Patent: June 5, 2001Assignee: Black & Decker Inc.Inventors: Alfred H. Judge, Richard J. Heavel, Robert H. Gifford

Patent number: 5823657Abstract: A lamp clamp uses a portion of the lamp as a moveable clamping jaw. This portion is screw-threaded into a threaded aperture of one of the arms of a C-shaped member. The other arm of the C-shaped member includes an object-engaging portion which further includes two pressure pads separated by a dished portion. The C-shaped member includes a coextensive flange around the inner periphery of the "C". The flange assists in stabilizing the clamp against the object, such as, the side edge of a worktable. The end of the moveable portion is attached to a swivel head which is pivotably engageable with the object in several orientations. The arrangement is especially useful when it is desired to mount a flashlight having a flexible stem (such as the Black & Decker.RTM. SnakeLight.TM. flashlight). The moveable clamping jaw defines a cylindrical tube into which is slideably mounted the graspable portion of the flashlight.Type: GrantFiled: August 9, 1996Date of Patent: October 20, 1998Inventors: Scott D. Price, Alfred H. Judge, Thomas J. Wheeler, Robert H. Gifford
