ABSTRACT:
A motor driven cam and spring impact tool having a buffer spring for absorbing energy when all of the energy cannot be transmitted out of the working tool into the workpiece. A hammer is carried in the housing and reciprocated by an annular cam and roller assembly. A working tool is aligned with the hammer for transmitting energy from the hammer to the workpiece. A tool guide is carried in the housing and has an axial passage for the working tool. The tool guide has an anvil on the end next to the hammer for receiving blows should the upper end of the working tool be within the axial passage. The tool guide is supported in the housing by an annular buffer ring of spring steel. The buffer is arcuate, allowing it to buckle a selected amount to absorb energy.
