Patent ID: 7721633

Claim:
A double bevel table saw comprising: a. a generally horizontally disposed platform having a working surface, an underside, a saw slot, a saw slot axis, and a first side and a second side of said platform at opposite ends of said slot; b. a frame supporting said platform, having a first side and a second side corresponding to said first side and said second side of said platform; c. a support rack gear, being noncircular and arcuate, mounted along the inside of each said first side and said second side of said frame; d. a supporting cradle pivotally disposed beneath the platform, pivotal substantially about said slot axis, in two directions substantially from the vertical, said cradle having a first side and a second side corresponding to said first side and said second side of said frame respectively; e. a radial alignment guide assembly mounted on the inside of each said first side and said second side of said frame, for slidably engaging said cradle and said frame, the guide assembly allowing radial and rotational variation of the cradle's position substantially relative to said saw slot axis; f. a saw assembly pivotally mounted on said supporting cradle, comprising a saw motor to which a circular saw blade is attached, wherein said saw assembly is pivotal in a path that permits the saw blade to be projected upward through and retracted downward from said saw slot, between a maximum exposure position and a recessed position respectively, further, the tilt angle of the saw blade equals the pivot angle of the cradle; g. a bevel pinion gear mounted on each of said first side and said second side of the cradle, each said bevel pinion gear fixedly attached to a bevel adjustment through shaft, the adjustment shaft being rotatably attached to the cradle, parallel to the saw slot axis, and manually rotatable, each said pinion gear in secured, gravitationally biased, meshing engagement with the top of the corresponding rack gear, wherein the pinion gears and the rack gears coordinate with said radial alignment guide assemblies to support said cradle, control radial movement of said cradle with respect to said slot axis, and provide a cradle pivot assembly for tilting of the saw blade, with tilt adjustment being accomplished by manually rotating the pinion gears; h. maximum exposure adjustment means, whereby the maximum exposure of said circular saw blade above said working surface is automatically adjusted, wherein said maximum exposure adjustment means comprises said bevel pinion gears riding on said support rack gears, further, the design determined contours of the rack gears, automatically vary the slidable radial dimension of the path of the cradle with respect to said slot axis according to the bevel angle, automatically avoiding contact of said saw assembly with said underside of the platform at extreme bevel angles.
