  • Patent number: 8632285
    Abstract: A router table clamp system for attaching a router to a router table, wherein the system includes a first plate that is fixed with respect to the router table, a second plate that is configured to cooperate with the first plate to enable the router to be removably attached to the router table, and a clamping mechanism configured and arranged to move the second plate with respect to the first plate between a locked position and an unlocked position, wherein when the clamping mechanism is in the locked position, the router is securely attached to the router table. The clamping mechanism also includes a lever assembly configured and arranged to move the second plate in a locking direction and an unlocking direction, which directions are both generally coincident with a plane defined by the second plate, wherein the locking direction is opposite of the unlocking direction.
    Type: Grant

  • Patent number: 7984734
    Abstract: 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.
