THE Steam Engine, of which the principles are described in this work, may be suited to every purpose for which power is wanted. To apply it to drive mill-stones one cog-wheel on the shaft of the fly-wheel, geared into the trundle, will give the stone its proper motion. To saw timber one cog-wheel on the shaft of the fly, geared into a pinion on the crank of the saw, gives it motion; or, more simply, the saw and engine may both be attached to the crank of the fly, which in this case is made a double crank, and the engine made to strike as quick as the saw; for it will strike, as may be required, from 10 to 100 strokes per minute. To pump water the pump-rod may be attached to the same crank. To press the juice out of sugar canes one small pinion on the fly, gearing in a cog-wheel on the middle roller, gives the mill its proper motion. To work a rolling-mill, the rollers may be simply attached to the shaft of the fly. To work a forge-hammer the shaft of the fly may be made to lift the hammer; furnace bellows may simply be attached to the crank of the fly, and the flue of the furnace conducted under the boiler to drive the engine by the heat of the furnace. To propel a boat against the stream the paddle-wheel may be attached to the shaft of the fly-wheel, and the motion may be regulated by increasing or decreasing the motion of the engine. For this purpose this engine will answer better than any other steam engine heretofore used, because its power is five times as great in proportion to its weight and size, and the power may be augmented to a great degree and kept in reserve to ascend the most rapid currents. It will answer well to drive a land carriage with a heavy burden, because the engine and fuel will not make one-eighth of the load. A pinion on the shaft of the fly to gear into a , which is fixed on the axle of the two wheels, will give them motion forward or backward at pleasure, and enable the engineer to turn his carriage on a small space of ground. To raise coals and water out of mines it will also answer well. The shaft of the fly- wheel may wind the ropes to raise one bucket while the other descends; and as soon as the loaded bucket is up the engine may be made to stop of itself, empty the bucket and turn the other way to raise the other, and so on alternately; as it will turn either way with equal convenience, and pump water all the while.In the performance of all work that can afford the labour of men and horses, and to which the engine will apply, it will make, clear of all expenses, at least one dollar for every bushel of coals it burns, and more, even supposing the coals to cost forty cents per bushel. An engine that would cost 4 or 5000 dollars, will saw 6 or 8000 feet of boards in 12 hours, or grind 4 or 500 bushels of wheat in 24 hours, and clear 100 dollars per day in some parts of this country.
To chop grain and pump for distilleries and breweries, a very small engine will answer. The heat of the fire, after it leaves the engine with the steam, may be applied to heat the mashing tubs, &C and thus the fire may be made to answer a double purpose. In paper-mills the steam engine may be employed with peculiar advantage; the power to cut, clean and grind the rags and work the screws of the presses; and the steam to heat the vats. For turning-lathes and grind-stones, a very small and cheap engine will answer.
Persons desirous of procuring steam engines on the principles described in this work, may be supplied with them suitable for any of the above purposes by applying to the patentee. Any infringement of his exclusive right will be treated as -the act of Congress in such cases directs.
