AbstractAn impact tool includes a rotational energy device mounted within the housing of the tool. A driver is reciprocally mounted within the housing and is coupled to the energy device by a toggle member. The toggle member includes a clutch and is actuated to transfer energy from the energy device to the driver. The driver and toggle are driven through a power stroke upon engagement of the clutch with the energy device. Upon completion of the power stroke, the clutch engages a bumper removing the clutch from the energy device and the toggle and driver are returned by a return assembly driven by the energy device.A second embodiment of the tool includes a wheel rotatably mounted on the toggle. The driver is positioned between the energy device and the wheel such that once the wheel is moved by the toggle, the driver engages the energy device and is driven thereby.
