Abstract: 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.

Abstract: Table saws are disclosed. The table saws can include a blade, an arbor, an arbor block, an elevation carriage, and a latch that connects the arbor block and the elevation carriage. The arbor block can have a first position in which the latch connects the arbor block and the elevation carriage, and a second position in which the latch does not connect the arbor block and the elevation carriage. The arbor block can pivot from the first position to the second position upon the occurrence of a retraction force. The table saw can include an actuator to cause the occurrence of the retraction force, and detection electronics to detect contact between the blade and a person. Woodworking machines with detection and reaction systems are also disclosed. A reaction system can include an explosive that causes retraction of a cutting tool.

Abstract: Fences for use in table saws are disclosed. One embodiment may include an actuator, handle or lever to lock and unlock the fence from the table, where the actuator, handle or lever is positioned substantially above the tabletop and substantially within the perimeter of the table (including any rail associated with the table). Another embodiment may include an actuator, handle or lever to lock and unlock the fence from the table, where the actuator, handle or lever is positioned along a top surface of the fence and configured so that the fence unclamps from the saw when the actuator, handle or lever is pressed.

Abstract: Power tools with conductive couplings used with active injury mitigation technology are disclosed. Conductive couplings are particularly relevant to table saws, hand-held circular saws, track saws, miter saws, and band saws with active injury mitigation technology. Conductive couplings provide a mechanism through which an electrical signal can be coupled or imparted to a blade, and then monitored for changes indicative of human contact with the blade. An exemplary conductive coupling includes a brush that establishes an electrical connection with a moving part of a power tool, and the brush maintains contact with the moving part of the power tool during at least 40 hours of cumulative time when the motor is spinning the arbor and blade without an interruption in the electrical connection sufficient to trigger the reaction system. A conductive coupling may be two-sided compliant. A conductive coupling may connect to a motor shaft to minimize electrical noise.

Abstract: Inserts for use in table saws are disclosed. One embodiment may include a mechanism to lock mechanically and affirmatively the insert in a blade opening in a table saw. The mechanism is designed so that a user can install and remove the insert without tools. The mechanism also can be designed so that the front of the insert pops up above the table when released from its locked position. The mechanism can be further designed so that the insert can be unlocked or released by a user pressing a button or tab.
