"Soon shall thy mighty arm, unconquer'd steam, afar,
Drag the slow barge, or drive the rapid car;
Or, on broad, waxing wings, expanded, bear
The flying chariot through the fields of air!"
Improvement in the application of Steam - We have at various times, during the past season, been highly gratified by an examination of a miniature semi-rotary steam engine, (possessing the advantages of the rotary principle without the difficulty of keeping the packing impervious to steam) in its several stages of completion, at the shop of our neighbour and ingenious fellow citizen, Ogden Mallory.
From our first examination of the piece of mechanism, we were satisfied of its improvement, and convinced of its ultimate utility - we therefore were directed with increased satisfaction; and a few days since had the pleasure of examining a neatly finished model of which has since been sent to the patent office at Washington.
The great desideratum in the application of steam is to gain the same power, with a reduction in the complication of machinery. The more simple and less complicated the machinery, the less power will be lost, and a great gain in expense saved to the builder. In this particular, in our opinion, Mr. M. has succeeded in a very eminent degree. In the model which we examined, the engine, or cylinder in which the power is applied, allows a piston of only two superficial inches, and this is sufficient to propel a small turning lathe; another advantage obtained by having the whole, or nearly so, constantly before the eye, is the liability of getting out of order avoided, or should it get out of repair, an opportunity immediately offered of correcting the error.
Another improvement, which has long been a "consummation devoutly to be wished," is an improvement whereby the the liability to accidents from bursting of boilers is entirely removed. This is done by the machine feeding itself with a suitable quantity of water, and regulating itself by its own power.
There are other improvements of vast importance - the weight of the machinery will not exceed half that of those now in use, and the room required for the same will be reduced in the same ratio.
It gives us pleasure to add, while on this subject, that Mr. M. is now engaged to build an engine on this principle of ten horsepower, for one of our enterprising citizens, which will fully display its advantages and improvements over any other now in use. In the mean time, we wish Mr. M. may meet with encouragement commensurate with his merits, by his own countrymen, and that he may not be compelled, like most Americans, to seek support in a foreign land.
