ABSTRACT:
A tool elevation and bevel adjustment machanism for a direct drive power tool (e.g., a direct drive table saw) is disclosed in which the power tool's drive motor is mounted on a plate which is pivotally suspended below the work table of the power tool. A working tool (e.g., a circular saw blade) is mounted on the rotor shaft of the motor. The plate with the motor mounted thereon is selectively pivotal with respect to the work table by means of a screw linkage such that the plate, together with the tool, may be selectively adjusted with respect to the table such that the tool is either perpendicular to the work table or is at a desired bevel angle with respect to the work table. Additionally, the motor is pivotally mounted on the plate for arcuate movement with respect to the plate. An elevation adjustment screw linkage is provided for effecting arcuate movement of the motor with respect to the plate, which in turn effects changes in elevation of the tool with respect to the work table, regardless of its bevel angle with respect to the work table.
