  • Patent number: 4108225
    Abstract: A portable electric router comprising a base having a dust chamber formed below a motor mounted to the base to be axially adjustable therein. A pair of handles are connected to the base with a passage formed in one of the handles in communication with the dust chamber. A blower is formed on the top side of the motor with the router connected to and driven by an extension from the motor armature shaft. A flexible conduit interconnects the handle passage and the blower, and a dust bag collects the dust and debris from the blower discharge. The conduit which interconnectes the handle and blower is flexible to permit axial adjustment of the motor within the base. The motor is journaled in a housing the lower half of which is threaded to receive an internally threaded ring member having outer and inner rings. The outer ring has a flat bottom which sits upon an annular flange formed at the top of the base. Rotation of the outer ring will raise or lower the motor housing to adjust the depth-of-cut.
