...carriages or wagons, advances, so that its progressive motion in a single revolution of the working-wheels is equal to their circumference. Supposing their diameter...progressive motion of sixteen feet, four cylinders full of s'-eam are necessary, being at the rate of about a cylinder for every four feet. Now, from these circumstances,... | |

...the piston travels in a minute is found by multiplying the length of stroke which it makes in going from one end of the cylinder to the other, and back again, by the number of such strokes made in a minute. The total pressure on the piston of any engine, and... | |

...to the valve, but while it travels from 1 to 2 the valve is opened and shut. Now, then, inasmuch as the piston moves from one end of the cylinder to the other for each semi-revolution of the cam, and inasmuch as the distance from a to 1 is the same as from 1... | |

...the cylinder through the same openings. From what has been said it is obvious, too, that every time the piston moves from one end of the cylinder to the other the valve must also be moved back and forth in the steam-chest. This is done by what is called an eccentric.... | |

...that end, and hence is called the refrigerator. The object of the p'unger is to transfer a mass of air from one end of the cylinder to the other and back again, and so on alternately, which is accomplished by the reciprocating motion of the plunger. The plunger... | |
