ABSTRACT:
This invention relates to an improved pneumatic power driving tool for driving staples, nails and other fasteners. The tool is comprised of a pneumatically operated pivoted rectangular hammer which is used as the means for delivering a force to a ram which in turn drives the fastener. The pressure in an air reservoir provides means for determining the impact of the hammer in this tool. A hammer activated valve is employed to index a fastener before a driving force is applied to the fastener by the hammer.
