This engine evaporated eight cubic feetof water per hour, consumed seventy-five poundsof coal per hour, and could haul ninety-four tonson a level track at a rate of three and one-halfmiles an hour. 42 RAILWAY EQUIPMENT. Hedleys locomotive, Puffing Billy, had awrought-iron boiler with a return flue, and twovertical cylinders; the piston rods were con-nected to beams and motion was communicatedto the four smooth driving wheels by means oftoothed-gear; the exhaust steam was dischargedinto the chimney by two blast-pipes. The first locomotive built by George Stephen-son, called the Blucher, ran upon four smoothwheels three feet in diameter, which w^ere placed r^. The Camel. 1848. Built by Ross Winans of Baltimore. A chute was pro-vided for feeding coal through the top of the fire-box. five feet apart between centers. Its boiler waseight feet long, thirty-four inches in diameter,with a flue-tube passing through it of twentyinches diameter. It had two vertical cylinderseight inches in diameter with a twenty-four inchstroke, the power of which Avas communicatedby cross beams and connecting rods to cranks onthe spindles of spur wheels, which in turn actedupon the large cog wheels on the engine engine was without springs and the cogwheel gear soon became worn with use. EVOLUTION OF LOCOMOTIVE. 43 The pictures of these four engines, just<lescribed, accompany this, and, taking theirmachinery as a basis, we may go forward andnote some of the more important changes whichhave since occurred in the evolution of theengine.
