After a little Googling I found a claim that the gun was actually invented by C.S. Dickinson but built by Winans. Perhaps US Paten 24997 (http://www.google.com/patents?id=QlhhAAAAEBAJ&dq=24997+dickinson ) is the relevant one. It only indirectly used steam power to shoot the projectiles using centrifugal force.
