Abstract

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.
