Abstract

The invention is directed to a power tool apparatus such as a table saw which includes a housing having a table top with an appropriate opening for a motor driven tool. Pivotally mounted within the housing is an assembly which in the disclosed embodiment includes a frame having a subassembly pivotally mounted therein. A subassembly includes the tool, such as a saw blade, and the means for driving same. A first control includes a lever connected to the subassembly for pivoting same. The pivotal movement effected by the lever allows for quick and coarse setting of the tool at a desired elevation with respect to the tabletop. The control lever further includes a locking arrangement disposed thereon which is manipulatable by the same hand used to coarsely set the tool elevation. The locking arrangement secures the lever to the frame at the desired coarse setting. A second control means likewise operable by the same hand of the operator, is connected to the subassembly, whereby the subassembly is pivoted independently of the first control. This second control provides a vernier adjustment of the tool. The assembly can be pivoted about its pivot mount in the housing in order to change the relative angle of the tool to the tabletop so that bevel cuts can be made.
