A dust-tight housing for confining, collecting and removing sawdust created by a power table saw, whereof the circular saw blade is affixed to a rotatable shaft located below the work table. The saw blade has its upper portion protruding through a slot in the table. Its lower portion is enclosed in dust-tight relation within the housing. The housing is mounted to the understructure of the power table saw so that it is moveable angularly in harmony with the angular movements of the saw blade. The housing remains stationary during vertical movements of the saw blade. The side walls of the housing are provided with moveable elements which permit dust-tight passage of the saw blade shaft into the housing, and which provide for ease of access for removal and replacement of the saw blade. The moveable elements are automatically adjustable, upon vertical or angular movement or displacement of the saw blade, to maintain the dust-tight character of the housing at all times. The moveable elements accommodate the shaft at any selected location of the saw blade while providing a dust-tight closure about the shaft and the opening through which the shaft extends into the housing. The housing is adaptable for use with other power table tools, such as dados, sanders, grinders, shapers, etc.

In a power saw having a saw blade mounted on a rotatable shaft which is disposed below a slotted work table through which the saw blade protrudes upwardly to work sawing position, said saw blade and shaft being selectively displaceable vertically and angularly relative to the table and being connected for angular movement to a selectively tiltable support cradle, a dust confining and collection housing surrounding the portion of the saw blade below the table comprising (a) a hollow enclosure having spaced side and spaced end walls, said enclosure having an open top disposed in contiguous relation to the table and an open bottom connected to a source of suction, (b) fastening means securing the enclosure to the tiltable support cradle, whereby the housing is rendered angularly moveable in harmony with and in fixed relation to the angular movement of the saw blade and shaft, (c) a first side wall of the enclosure having a stationary component and a slidable component moveable up or down relative to the stationary component, (d) resilient means disposed on the enclosure for maintaining the slidable component of the first side wall in contiguous relation to the table when the saw blade, shaft and housing are displaced angularly relative to the table, (e) a second side wall of the enclosure having an opening through which the shaft for the saw blade extends, said opening being larger than the cross section of the shaft to permit the saw blade and the shaft to be displaced vertically relative to the table and the enclosure, and (f) shutter means disposed on the enclosure for maintaining the open portion of the opening in the second side wall closed at each location to which the saw blade and shaft are displaceable relative to the table.
