A dust collector has a shroud mounted to the connecting rods of the pivoting assembly of a contractor's table saw. The shroud is configured to surround the lower portion of the saw blade when the blade is fully raised, and most of the blade's diameter when it is fully lowered. The shroud is equipped with a nozzle for connection of a dust collection hose. The shroud extends upwardly between the connecting rods of the pivoting assembly and between the front and rear trunnions. The longitudinal outside surfaces of the shroud are provided with shoulders that abut the connecting rods. Retainers engage the connecting rods to support the shroud against the shoulders. Thus, the dust collector is suspended below and removably connected to the pivoting assembly of the table saw. One corner of the shroud includes an opening to accommodate the arbor bracket and its vertical movement.

The invention claimed is: 1. In combination, a dust catcher and a contractor's table saw, said contractor's table saw comprising: a table and beneath the table a pivoting assembly including front and rear trunnions secured to each other by a pair of connecting rods and an arbor bracket arranged to pivot on said front trunnion, said arbor bracket supporting an arbor shaft and a saw blade for rotation on said shaft, the blade being positioned between said connecting rods and parallel thereto, said arbor bracket pivots in a plane parallel to said connecting rods and perpendicular to said front trunnion to raise and lower the arbor shaft and saw blade relative to the table and the front trunnion of the table saw includes a concave configuration to accommodate the saw blade when the arbor bracket is pivoted to lower the saw blade relative to the table, said dust catcher comprising: a shroud securable to said pivoting assembly for movement therewith, said shroud comprising side walls parallel to said connecting rods and end walls perpendicular to said connecting rods, said side walls and end walls defining an elongated dust collection space between the connecting rods and substantially surrounding the saw blade beneath the table, said front end wall comprising a front plate configured for reception into the concave front trunnion and substantially close a portion of said front end wall adjacent the front trunnion, said front plate including a slot which receives a portion of the saw blade when in a lowered position; and a dust collection nozzle extending from a lower portion of said shroud. 2. The combination dust catcher and contractor's table saw of claim 1, wherein said side walls include an arbor side wall and a front end wall meeting to form a corner of said shroud adjacent said front trunnion, said arbor side wall and front end wall including an open portion configured to accommodate movement of the arbor bracket, arbor and blade relative to the shroud. 3. The combination dust catcher and contractor's table saw of claim 1, wherein each said side wall having an outside surface and each said side wall includes at least one shoulder laterally extending from said outside surface to engage an adjacent connecting rod. 4. The combination dust catcher and contractor's table saw of claim 1, wherein said front plate is a separate component from said shroud. 5. The combination dust catcher and contractor's table saw of claim 1, wherein said front plate is integral to said shroud. 6. A dust catcher and table saw in combination, said table saw having a fixed table and a saw blade assembly supported beneath the table for vertical and angular adjustment of a circular saw blade relative to the fixed table, said saw blade assembly including front and rear trunnions coupled by connecting rods parallel to said saw blade and an arbor bracket supporting an arbor shaft on which the saw blade is mounted for rotation, said arbor bracket pivotably supported on said front trunnion, said saw blade assembly being rotatable about a longitudinal axis parallel to said connecting rods to facilitate angular adjustment of said saw blade with respect to said fixed table, said dust catcher comprising: a shroud defining a dust collection space between said connecting rods and substantially surrounding the saw blade beneath said fixed table, said shroud attached to said saw blade assembly for rotation therewith and defining an open portion adjacent said front trunnion configured to accommodate vertical adjustment of said arbor bracket and saw blade between a raised and a lowered position with respect to the fixed table and including a dust collection nozzle extending from a lower portion of said shroud, and a front plate including a slot configured to receive a portion of the saw blade when the saw blade is in the lowered position, said front plate being a separate component configured to at least partially close said open portion. 7. The dust catcher and table saw combination of claim 6, wherein said shroud includes lateral projections and retainers arranged to releasably secure the shroud to the saw blade assembly. 8. The dust catcher and table saw combination of claim 7, wherein an end of said shroud is configured to surround a lower portion of the saw blade in the lowered position. 9. A dust catcher in combination with a table saw having a table and beneath the table a pivoting assembly including front and rear trunnions secured to each other by a pair of connecting rods and an arbor bracket supporting an arbor shaft and a saw blade for rotation on said shaft, the saw blade being positioned between said connecting rods and said arbor bracket being movable relative to said front trunnion to raise and lower said arbor and blade relative to said table, said front trunnion including a concave configuration to accommodate a portion of the saw blade when the arbor bracket is pivoted to lower the saw blade relative to the table, said dust catcher comprising: a shroud defining a dust collection space between the connecting rods and front and rear trunnions, said shroud substantially surrounding the saw blade beneath the table, said shroud having a front end adjacent said front trunnion, said front end configured to accommodate the saw blade in a lowered position and lateral projections and retainers to releasably secure the shroud to the pivoting assembly for movement therewith, said front end including a separate front plate configured for reception into the concave front trunnion and securable to said shroud to cover an opening in the front end of said shroud, said front plate including a slot configured to receive a portion of the saw blade when in a lowered position.
