<p>Elevation setting mechanism for a motor-driven tool in a power tool apparatus such as a table saw. The table saw described includes a housing (20) having a table top (26) with an opening through which the saw blade (43) can pass, and an assembly including a frame pivotally mounted in the housing (20) about a first axis. Pivotally mounted in the frame about a second pivot axis is a first subassembly which includes the saw blade (43). Further, there is included a second subassembly pivotally mounted about the second pivot axis. The basic elevation setting mechanism includes a control lever (44) operatively connected to the second subassembly for pivoting same. The mechanism further includes a second control mechanism (52) operatively connected to the first subassembly for imparting additional pivotal movement thereto for effecting a vernier elevation adjustment of the saw blade (43).</p> |
