Mechanism for Regulating Steam-Engines
|
Henry James Johnson |
Providence, Providence County, RI |
Abstract:
In drop cut-off valve engines in which the governor regulates the point at which the cutoff takes place-such, for example, as the engine known as the "Greene Engine"-it sometimes happens that the driving-belt of the governor breaks or runs off the pulley, in which cases the steam-valves cease to cut off the admission of steam from the boiler, and unless the engineer is at hand to close the throttle-valve the engine receives far more steam than is necessary for the work to be performed and suddenly increases its speed.
Claim:
The combination, substantially as before set forth, of the governor-slide, the tappets which operate the steam-valves of the steam-engine, with the intervening connecting rod, and the shifting link of that rod. |
