Publication number: 20120318547Abstract: A power tool with a multi-speed transmission and a switch mechanism for shifting the transmission between a plurality of different speed ratios. The switch mechanism includes a single switch member that is slidably mounted on the housing. The power tool further comprises a clutch having a clutch profile that is coupled to a ring gear of the transmission. In some examples, the power tool further comprises a clutch that is configured to interact with a first stage of the transmission.Type: ApplicationFiled: June 21, 2012Publication date: December 20, 2012Inventors: Rodney Milbourne, Christine Potter, Gerald Rescigno, Qiang Zhang

Patent number: 8220561Abstract: A clutch arrangement that includes a clutch member and a follower member. The clutch member is coupled to a member of the transmission assembly that is proximate the torsional input of the transmission assembly and which must be in a non-rotating position to permit the transmission assembly to perform a torque multiplication operation. The follower member is biased into engagement with the clutch member to inhibit relative rotation therebetween. As the clutch member and the transmission member are coupled to one another, the transmission assembly is able to perform a torque multiplication operation. When, however, the torsion that is exerted onto the clutch member is sufficient to overcome the frictional engagement between the follower and clutch members, the clutch member, and the transmission member, rotate, thereby inhibiting the capability of the transmission to continue to perform the torque multiplication operation.Type: GrantFiled: December 13, 2010Date of Patent: July 17, 2012Assignee: Black & Decker Inc.Inventors: Rodney Milbourne, Christine Potter, Gerald Rescigno, Qiang Zhang

Patent number: 7237986Abstract: A metal cutting drill bit has a shank portion, a flute portion defining a helix angle and a tip. The tip has a primary cutting edge extending to an outer periphery of the drill bit. The primary cutting edge has a rake face defining a rake angle. The rake angle is different from the helix angle at the tip of the drill bit.Type: GrantFiled: August 9, 2004Date of Patent: July 3, 2007Assignees: Black & Decker Inc., University of MarylandInventors: Muniswamappa Anjanappa, Li Xu, Stephen R.

Patent number: 6857983Abstract: A clutch assembly for limiting a torque output of the power tool. The clutch assembly includes an annular rotatable clutch member, which is coupled to the ring gear of a planetary gearset in a transmission, and an engagement assembly. The clutch member has a clutch face with a predetermined clutch profile. The engagement assembly has at least one follower member that abuts the clutch member and cooperates with the clutch profile to inhibit rotation of the clutch member relative to the follower member only when the magnitude of the torque output of the power tool is less than a predetermined maximum torque. The clutch face on the clutch member is located between the opposite axially ends of the ring gear.Type: GrantFiled: January 9, 2004Date of Patent: February 22, 2005Assignee: Black & Decker Inc.Inventors: Rodney Milbourne, Christine Potter, Gerald Rescigno, Qiang Zhang
