摘要： Elevation mechanisms for table saws and anti-backdrive mechanisms for use in elevation mechanisms for table saws are disclosed. The anti-backdrive mechanisms typically include three sub-assemblies: an input assembly, an output assembly, and a fixed assembly. The anti-backdrive mechanisms prevent a torque related to the output assembly from changing the blade elevation. For example, the weight of the blade and the structure supporting the blade is prevented from backdriving the elevation mechanism and allowing the blade to drop.

摘要： Mounting systems to secure and index riving knives and spreaders in table saws are disclosed. One embodiment may include three mounts or screws attached to an elevation carriage. A clamp plate fits over the heads of the mounts and a handle pivots to move the clamp plate against flanges on the heads of the mounts to clamp a riving knife or spreader in place.
