ABSTRACT:
A percussion tool, disclosed as a nail driver, having a plunger-like hammer or driver which is driven through working and return strokes by a power piston movable in a cylinder which is pressurized with a working fluid and vented by selective actuation of a unique and simplified valving arrangement to effect the working and return strokes. The disclosed nail driver has a nail magazine which is attached to the tool in a novel and rugged manner which resists bending and other damage of the magazine by the periodic impact forces generated in the course of nail driving operation of the tool.
