Abstract: An impact tool having a split anvil assembly includes an internal anvil portion fixed inside a housing of the impact tool and an external anvil portion that is removably attached to the internal anvil portion and extends outside of the housing. The external anvil portion includes a retractable pin biased to an extended position to engage the internal anvil portion to secure the external anvil portion to the internal anvil portion and depressed to a retracted position to permit the external anvil portion to be disengaged from the internal anvil portion. The internal anvil portion and the external anvil portion may include respective internal and external grooves that interconnect with each other to link the movement of the internal anvil portion to the external anvil portion.

Abstract: A power tool comprises an adjustable auxiliary handle assembly that facilities safe use of the tool by the operator when handling heavy duty handheld machinery. The adjustable auxiliary handle assembly comprises a strap, a handle base, an over-center linkage assembly, a locking lever, a locking lever and an adjustable knob. The strap is easily released and able to rotate and be locked in a different position convenient and comfortable to the operator. The auxiliary handle assembly is adjustable and can be operated with one hand (e.g., one-handed operation). The over-center linkage assembly holds the auxiliary handle position in place while allowing the power tool to be used in high-torque/high load applications.

Abstract: Improved radial pneumatic regulator systems, devices and methods are described herein. Embodiments may comprise regulators with adaptive radial seals to prevent air leakage, provide increased air supply use efficiency, and facilitate more efficient manufacture and assembly of systems. The regulator systems may be used in applications such as for pneumatic power tools.

Abstract: A swinging weight assembly for an impact tool includes an anvil having an impact jaw that is reinforced with a circumferential flange. A hammer includes a hammer lug and a cam lug for pivoting the hammer between an engaged position in which the hammer lug strikes the impact jaw and a disengaged position in which the hammer moves past the impact jaw. The cam lug is separated from the cam lug to define a space in which the reinforcing flange is received.
