Abstract
The front panel of a table saw has a lever which controls the elevation of the saw blade relative to the saw table. The elevation control lever is also coupled to a bevel control means for tilting the saw blade (and its driving motor) with respect to the table. The combination of these translational and bevel movements results in a relatively large traverse of the elevation control lever. The elevation control lever projects through an opening in the front panel of the housing for the table saw, and this opening is of sufficient size and shape to accommodate the total excursion of the elevation control lever in its traverse. An articulated cover means is provided within the housing to prevent dust from entering into the housing via the opening, as well as to prevent inadvertent contact with the operating mechanism. This articulated cover means includes a first cover member which is disposed substantially flush against the opening on the inside of the front panel. This first cover member, which pivots in response to pivotal movement of the bevel control means (and the elevation control lever coupled thereto) has a size and shape sufficient to substantially cover the opening in the f…
