Patent number: 11303067Abstract: It is common for a power tool system from a manufacturer to include a battery pack that is designed and configured to mate and operate with at least one power tool and a battery charger. However, as systems have evolved it has become desirable to provide a battery pack that is designed and configured to mate and operate with at least one power tool and a first battery charger but not a second battery charger. The present disclosure provides a battery pack including a housing, a terminal block, a plurality of terminals, and a mechanical lockout for allowing engagement with a power tool and a first battery charger while preventing engagement with a second battery charger.Type: GrantFiled: February 27, 2017Date of Patent: April 12, 2022Assignee: Black & Decker Inc.Inventors: Nathan J. Cruise, Daniel J. White, Robert J. Marcinkowski, Geoffrey S. Howard, Alexis W. Johnson, Nathan J. Osborne, Michael W. Roberts, Steven J. Phillips, Michelle L. Bowers

Patent number: 7135796Abstract: An electrically conductive brush box is located against the upper surface of a base and has crimping tabs located against an oppositely disposed crimping surface. The base is formed of high temperature resistant plastic. A field case housing has a seat with a retention member adapted to retain the base against the seat. A screw is threaded into the field case housing such that the head presses against a surface of the base member to retain the base member in the seat. The screw member is located in non-contacting relationship with the electrically conductive brush box. A spacer member is adapted to space the portion of the crimping tab against the crimping surface away from the field case housing. The brush box includes a biasing member holder and the crimping tabs are located adjacent the holder.Type: GrantFiled: April 29, 2005Date of Patent: November 14, 2006Assignee: Black & Decker Inc.Inventors: Earl M Ortt, Robert J Marcinkowski, Michael J Agnes, Mark D Williams

Patent number: 7126242Abstract: A field case housing has a substantially cylindrical wall segment, an end segment and a flange all having a substantially constant wall thickness. The flange has reinforcing ribs connected to the wall segment and aperture reinforcing bosses. The end segment, the wall segment and the flange are formed as a single, integral part adapted to reduce warping of the housing during molding. A cylindrical guide member is located in the field case housing and a conical guide member is located in the fan baffle. The cylindrical guide member is adapted to insure a screw passing through the cylindrical guide member is guided to a point within the conical guide member. The fan baffle has a transverse wall with an aperture and guide walls extending adjacent the aperture. The guide walls are adapted to guide an armature past the magnets without contacting and damaging them.Type: GrantFiled: April 29, 2005Date of Patent: October 24, 2006Assignee: Black & Decker Inc.Inventors: Robert B.
