ABSTRACT:
A pneumatic driver is disclosed. The pneumatic driver includes a frame and a shaft movable between an extended driving position and a retracted position relative to the frame. A first inflatable air bladder is supported by the frame. The first inflatable air bladder is operatively connected to the shaft so that when the first air bladder is inflated, the shaft is moved into an extended driving position. A second inflatable air bladder is supported by the frame and operatively connected to the shaft. When the second air bladder is inflated, the shaft is moved to a retracted position. A valve manifold operatively connects first and second air bladders for controlling inflation and deflation of the air bladders. The frame includes longitudinal guide rods and transverse frame members fixed to the guide rods. A shaft support member having the shaft mounted thereto is slidably mounted on the guiderods. Support rods are mounted to the shaft support member by bolts received in orifices to provide a clearance fit.
