Patent number: 7537064Abstract: A power tool with a housing, an electric motor having an output shaft that provides a first output torque, a first gear reduction element driven by the output shaft to provide a second output torque, a second gear reduction element, which can be operated in active and inactive modes, driven by the first gear reduction element to receive the second output torque and to provide a third output torque, a third gear reduction element, which is operable in active and inactive modes, driven by the first gear reduction element to receive the second output torque and to provide a fourth output torque, an output spindle operably driven by the second gear reduction element or the third gear reduction element, and a shift actuator. The shift actuator is employed to position the second and third gear reduction elements to achieve at least three overall speed ratios.Type: GrantFiled: September 28, 2005Date of Patent: May 26, 2009Assignee: Black & Decker Inc.Inventors: Rodney Milbourne, Christine Potter, Todd A Hagan, Michael C. Bowers

Patent number: 7223195Abstract: A portable power tool with a housing, a motor having a motor output member, a driven member and a transmission. The transmission, which is located in the housing, is configured to receive a rotary input from the motor output member and to produce a rotary output that is transmitted to the output spindle. The transmission has a plurality of planetary transmission stages, each of which including a ring gear, a planet carrier and a plurality of planet gears that are supported by the planet carrier for meshing engagement with the ring gear. The transmission further includes at least one member that may be configured in a first condition, which renders at least one of the planetary transmission stages operable in an active mode, and a second condition, which renders at least one of the planetary transmission stages operable in an inactive mode. The transmission is operable in at least three overall speed reduction ratios.Type: GrantFiled: August 18, 2006Date of Patent: May 29, 2007Assignee: Black & Decker Inc.Inventors: Rodney Milbourne, Christine Potter, Todd A Hagan, Michael C Bowers

Patent number: 7220211Abstract: A multi-speed transmission assembly for a rotary power tool. The transmission assembly includes a plurality of transmission stages, with at least two of the transmission stages employing a movable reduction element that permits the transmission stage to be operated in an active mode and an inactive mode. The movable reduction elements are coupled to a switching mechanism that switches the reduction elements in a predetermined manner to provide at least three-gear reduction or speed ratios.Type: GrantFiled: September 29, 2004Date of Patent: May 22, 2007Assignee: Black & Decker Inc.Inventors: Christine Potter, Rodney Milbourne, Todd A Hagan, Michael C Bowers
