... has given them a tonnage to be started and stopped twice in every revolution
of the driving wheels that should have prohibited the use of such heavy
reciprocating parts before now , For this and other reasons , our locomotive
builders have.

... designs of steam valves , but all do practically the same work : that of admitting
and releasing steam to and from the cylinder in which the energy of the steam is
transformed into piston power — the power that makes the wheels go ' round .

In starting the engine , if we should pinch the wheel backward , the eccentric
would pull the valve backward also , and steam would be admitted to the forward
end of the cylinder , pushing the piston back in spite of our efforts , and it would
