Patent ID: 7356930

Claim:
A dust mechanism for directing a flow of air onto a working member of a power cutting tool having a housing, a motor in the housing, a working member actuated by said motor and a shoe pivotally mounted relative to the working member and adapted to engage a workpiece, the dust mechanism comprising: a connector piece having an input port that is connected to a duct in the housing, wherein said input port receives the flow of air from the housing in a direction generally in line with an axis of pivotal movement of the shoe relative to the housing and wherein said connector piece is operable to rotate relative to said duct in the housing when the shoe pivots relative to the housing and while said connector piece is fluidly connected to said duct; and a bridge member fluidly connected to said connector piece and removably connected to a top surface of the shoe opposite a surface adapted to engage the workpiece, wherein said bridge member defines a generally hollow channel that terminates at an exit port from which the flow of air from said duct in the housing is directed onto the working member in a direction transverse to a line of action of the tool.
