LOCOMOTIVES

Locomotive engines, or simply locomotives, are steam engines which, mounted on a carriage, propel themselves by transmitting their motion to wheels.

The parallel motion, the beam, and the fly wheel of the ordinary stationary engine form no part of a locomotive. The principal parts are the framework, the fire box, the casing of the boiler, the smoke box, the steam cylinders, with their valves, the driving wheels, and the feed pump.

The framework rests on the axles of the wheels. The [illustration] on another [page] shows clearly the arrangement and parts of a typical locomotive. It will be observed that in the lower part of the steam dome is the fire box, from whence the flame and the products of combustion pass into the smoke box, and then into the chimney after having previously traversed the numerous brass fire tubes which pass through the boiler. The boiler, which connects the fire box with the smoke box, is made of iron, and is cylindrical.

The steam passes from the boiler into two cylinders, placed on either side of the smoke box. There, by means of a steam chest similar to that already described, it acts alternately on the two faces of the piston, the motion of which is transmitted to the axle of the large driving wheels. After having acted on the pistons, the steam is forced through the blast pipe into the chimney, thus increasing the draft.
