A steam drill is powered by a remote boiler while a length of steel hammered away at the rock face. It took the ingenuity of an American inventor named Simon Ingersoll in 1871 to come up with a device that rotated as well, effectively creating the first hammer drill.
Whilst they dont really appear to be working a "rock face" I dont know enough, (actually SFA) about this to comment further
re post 2725 & 2726. I'd say steam powered equivalent to modern jack-hammers, especially with Ingersoll connection. What too is interesting, some have a heavier supporting tripod and a hand crank; to feed the thing in.
They are a lot like today's portable hot-tap device.
