Abstract
A fastener driving apparatus includes a spring anvil assembly that comprises a gas spring and an anvil. The end of the piston that extends out of the gas spring may be fixedly disposed against an object that is capable of exerting a force against the piston for at least a portion of the operational cycle. A drive mechanism acts on the spring assembly to store potential energy in the spring. The drive mechanism thereafter ceases acting on the spring assembly and the potential energy is released, causing the spring anvil assembly move and to separate from the drive mechanism for a period of free flight of the spring anvil assembly, the anvil thereafter moving to strike a fastener to drive the fastener into a substrate.
