Patent number: 8087437Abstract: A router includes a base, a motor housing supported by the base for movement along a first axis, and an adjustment mechanism having a shaft, with a thread portion, connected to the motor housing for rotation about a second axis. The adjustment mechanism also includes a unitarily formed lock mechanism supported by the base. The lock mechanism includes a thread-engaging member that, when engaged with the thread portion, causes small changes to the position of the housing relative to the base in response to rotation of the shaft. The lock mechanism is movable between an engaged position, in which the thread-engaging member engages the thread portion, and a disengaged position, in which the thread-engaging member disengages the thread portion and the housing is freely movable relative to the base to provide course adjustment of the position of the housing relative to the base.Type: GrantFiled: September 8, 2009Date of Patent: January 3, 2012Assignees: Techtronic Power Tools Technology Limited, Milwaukee Electric Tool CorporationInventors: Jay A. Goddard, Randy McDonald, Dale Borchardt, Troy Thorson, Jeffrey Hessenberger, Christopher Berg, Jeffrey Holly

Patent number: 7677280Abstract: A power tool, such as, for example a router. In some aspects, a router includes a base, a motor housing supported by the base, a motor supported by the motor housing, and a hand grip forming at least a portion of one of the base and the housing and being contoured to fit a hand of an operator. The one of the base and the housing may be grasped by the operator when the operator grasps the hand grip to control movement of the router on the work piece surface. In other aspects, a router includes a base, a motor housing supported by and movable relative to the base, and a motor supported by the motor housing. The base is contoured to fit a hand of an operator and includes at least one of a slot or a ridge to provide improved gripping for an operator.Type: GrantFiled: July 19, 2006Date of Patent: March 16, 2010Assignee: Milwaukee Electric Tool CorporationInventors: Randy McDonald, Dale Borchardt, Troy Thorson, Jeffrey C.

Patent number: 7669620Abstract: A router includes a base for supporting the router on a work piece surface, a motor housing coupled to the base for movement along a first axis relative to the base, a motor supported by the housing and operable to drive a tool element, and a cantilevered shaft rotatable about a second axis and oriented substantially parallel with the first axis and offset from the first axis. The shaft includes a first end supported by the motor housing, a second end, and a threaded portion between the first and second ends. The threaded portion is engaged with the base. Rotation of the shaft about the second axis causes movement of the housing relative to the base along the first axis.Type: GrantFiled: March 17, 2009Date of Patent: March 2, 2010Assignee: Milwaukee Electric Tool CorporationInventors: Randy McDonald, Dale Borchardt, Troy Thorson, Jeffrey C.
