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: Extension rails for table saws are disclosed. Some of the disclosed extension rails can be attached to a table saw without a user having to manipulate a lever or knob. Extension rails particularly relevant to portable table saws such as jobsite and bench-top table saws are disclosed, including extension rails that can provide 48? or more of cutting capacity on jobsite and/or bench-top table saws. A method of attaching extension rails to a table saw is disclosed that does not require the use of a tool or the manipulation of a knob or clamp.

Abstract: A router includes a housing and a motor assembly disposed within the housing. The motor assembly includes a driven shaft having a cavity on a first end of the driven shaft. The router includes a collet that is configured to mate into the cavity of the driven shaft with the collet being configured to grip a shank of a router bit. The router includes a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.

Abstract: A bit retaining system for a rotary tool or device such as a router is disclosed. The bit retaining system may include a collet assembly and a control assembly. The collet assembly may include a spindle, a collet adapted to receive the bit, and a collet nut. The collet assembly may further include a collet gear mounted on the collet nut and/or a spindle gear mounted on the spindle. The control assembly selectively engages the collet assembly to drive the collet nut and/or secure the spindle in a fixed position, preventing its rotation. In operation, a hand tool is utilized to engage the control assembly. This configuration enables a user to capture and release the rotary tool bit using one hand.

Abstract: A system for replacing a discharged battery in a vehicle featuring a trolley with wheels operatively connected to a driving mechanism, the trolley can be directed to a battery tunnel of a vehicle via sensors; a moving battery tray mounted atop the trolley via a hydraulic cylinder, which functions to move the moving battery tray upwardly and downwardly; a charged battery removably disposed atop the moving battery tray; a locking system for locking the charged battery into the battery tunnel of the vehicle. The system allows the trolley to deliver the charged battery from a charging station to the vehicle. The discharged battery is removed from the vehicle in the same process the charged battery is installed in the vehicle. The trolley can carry the discharged battery back to the charging station for recharging.

Abstract: A pocket hole jig tool system includes a base on which a workpiece is supported. A drill guide support is slidably mounted to the base. Drill guide bushings are movably mounted relative to the drill guide support for clampingly engaging the workpiece and for guiding a drill for engaging the workpiece. A stop collar assembly is adjustably mounted relative to the drill guide bushings to automatically ensure a proper pocket hole location and depth for the workpiece inserted in the tool system.
