We fired only one shot at the old steamer, which smashed her walking-beam, and disabled her.
But at length, in 1844, the steam-whistle was introduced, and the "walking-beam boys" were left without occupation.
As the shot had hit the walking-beam of the steamer, it was not probable that she was seriously injured in her hull, if at all.
Steam was let in below this plunger, and the walking-beam with which it was connected by a rod had that end of it raised.
There were two of these, with square pistons and a walking-beam between them.
One end of the walking-beam reaches to the center line of the well, where it connects with the pump shaft.
In the Newcomen engine the piston moved a walking-beam to which was attached a pump-rod.
Another swivel connects the upper end of the pitman shaft with the walking-beam.
It is five times a mans height from the platform to the top of the walking-beam.
I am sorry to say that three were injured by the falling of the pieces of the walking-beam.
