Patent number: 7984734Abstract: A router table comprises a table top, a bit mount, and a drive train. The bit mount is configured to hold a router bit such that the router bit extends from the table top defining a bit axis. The drive train is positioned under the table top and is operably connected between the bit mount and a drive coupling. The drive coupling is configured to engage a driven member, with the drive coupling defining a drive axis that is not coaxial with the bit axis. The driven member may be provided by a drive bit on a portable router secured to the table top. Operation of the portable router results in rotation of the driven member. Rotation of the driven member and associated drive coupling operates the drive train and results in rotation of the bit mount and associated router bit.Type: GrantFiled: July 31, 2008Date of Patent: July 26, 2011Assignee: Robert Bosch GmbHInventors: Carl Alexander Cepress, Bobby Brent Boyd, John Charles Derler, Stefanie Danielle Reynolds, Carl Christian Carlson

Patent number: 6619894Abstract: A plunge base router for use in an upright and an inverted position is disclosed. The router includes a depth adjustment mechanism, a depth stop mechanism, a post lock mechanism, and a return spring defeat mechanism. The depth adjustment mechanism includes a course adjustment mechanism and a fine adjustment mechanism to set the cutting distance of a bit. The course and fine adjustment mechanisms are usable in both the upright and inverted positions and the fine adjustment mechanism is operable without being reset throughout the full range of motion of the plunge router. The depth stop includes a mechanism for locking the end of a rod on the housing to the base in order to set the relative position in between the housing and the base. The depth stop also includes a plurality of steps for engaging the rod and permitting incremental passes of cutting at different depths with the router.Type: GrantFiled: August 29, 2002Date of Patent: September 16, 2003Assignee: S-B Power Tool CompanyInventors: Mary Hathcock, Carl Christian Carlson, Manfred Staebler

The router includes a depth adjustment mechanism, a depth stop mechanism, a post lock mechanism, and a return spring defeat mechanism. The depth adjustment mechanism includes a coarse adjustment mechanism and a fine adjustment mechanism to set the cutting distance of a bit. The course and fine adjustment mechanisms are usable in both the upright and inverted positions and the fine adjustment mechanism is operable without being reset throughout the full range of motion of the plunge router. The depth stop includes a mechanism for locking the end of a rod on the housing to the base in order to set the relative position in between the housing and the base.

Patent number: 5909987Abstract: A simple and quick manner for centering a sub-base of a fixed-base router. The sub-base is provided with two sets of peripheral holes and a large central opening. One set of holes is countersunk and receives flat-head screws; the other set of holes is counterbored and receives pan-head screws. The router is sent from the factory with the sub-base attached by the flat-head screws. To center the sub-base the flat-head screws are removed and the pan-head screws are inserted to loosely mount the sub-base. The counterbored openings are oversized to allow lateral movement of the sub-base. A cone element is installed in the collet and engaged with the sub-base through the central opening. The cone element fully abuts the opening to center the sub-base, the pan-head screws are tightened and the cone element is replaced by a router bit.Type: GrantFiled: June 24, 1998Date of Patent: June 8, 1999Assignee: S-B Power Tool CompanyInventors: John R.
