Abstract
A retractable dust control hood for a rotary table saw includes a generally hollow box member which is supported for movement between a working position directly over the saw blade and a retracted position substantially above the saw blade to permit ease of handling workpieces with respect to the saw and a saw support table surface. The hood is supported from a member disposed above the table surface by parallelogram linkage and a counterbalance mechanism including a rod extending between one set of parallelogram link members and a second set of parallelogram link members. A coil spring is disposed around the rod and acts to move the parallelogram link members relative to each other to counterbalance the weight of the hood. The hood includes a transparent window and a lamp for illuminating the interior space of the hood for ease of viewing the workpiece during operation of the saw. The bottom edge of the hood is provided with rub rails which minimize disfigurement of the workpiece when engaged by the hood and moving relative thereto.
