  • Patent number: 6619894
    Abstract: 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.

  • Patent number: 6488455
    Abstract: 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 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. 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.
