Another New VEotor,

From the New York Commercial Bu1etin.l
 Engineers, marine underwriters, and others to whose knowledge the facts have come, are deeply exercised by recent successes in the ap- plication of giant motor. The power is ob- tained from bisulphide of carbon long known to practical chemists, but for century vain efforts have been made to utilize it in driving machinery. Among other devices, glycerine was combined with the bisulphide with better results but complete success was not realized or claiEled until very recent date, when powerful and quickly generated vapor was obtained from mixture of bisulphide of car bon and petroleum.
 In the patent taken out by Messrs. Will Hams, Smith & Milligan, of Pittsburg, Pa., April 1st, 1879, the power is described as an Improvement in the motors for machinery The method of its operation IS the transmits sion of the chemical agents above described from the chamber of condenser to the boiler of an ordinary non-condensing steam engine. The boiler being filled with water heated to about 200 degrees 8 pressure as high as 20G pound per square inch is rapidly developed from the vapor thus generated, and easily controlled. As more definitely described in the letters patent, the iggt or volatile portion of the petroleum oil must be evaporated for the purpose of separating the gasoline and benzole from it prior to putting it in the boil CT; then apply the heat and charge the cham Der of the condenser; then open the valve so that the bisulphide will be forced by the pump gradually into the boiler; then. by contact with the previously heated petroleum oil and water, it is rapidly vaporized, forming force or pressure proportioned to the quantity in jected and the heat applied.
 tremendous energy IS thus made avail able for purposes of navigation, for driving locomotive engines, and is equally applicable | through the whole range of mechanical indus tries. The key to this success in generating power is found in the special adoption of pe- troleum to the object of bringing the bisul- phide into control, ,-in this respect compara- ble to the success of Morse in ''harnessing the lightning" Through this agency the bisul- phide is held ; it aids in it's condensation, and holds the sulphur of the bisulphide. Thus the vapor does it's work in the cylinder entire ly pure. In the application of this chemical mixture to the steam engine, no change of screw or bolt is required, d,-nothing more than the addition of condenser and pipes to con meet the s'exhaust" and the F'escape." The contents of the boiler returned without waste in an unhending circuit tho action of the bisulphide being in every respect the same as steam.
 perfectly uniform pressure can be pre- served as it is governed by the pump alone; otherwise, the amount of bisulphide in jected into the boiler, and not by the heat of the furnace. This system enables the engi- neer in any emergency to obtain instantly from 100 to 200 pounds pressure, or more if desired, without any alteration or change of the fire. Alocomotive engineer, for example, when approaching heavy grade, has but to use his pump injection and hold his power until the ascent is made.
 On elevated railways the new motor could be employed with incalculable advantage, at once removing all the fire, smoke and cinders, and no noise arises from the escapes and ex- haust. Merely bolt of iron-just this and nothing more-heated in furnace at the end of the route will produce all the heat needed to generate power. Again, the new agent is affirmed to be absolutely non-exp1osive it acts on boilers as hydraulic pressure, and can not be made to explode. Bisulphide vapor- izes at 110 degrees, saving 72 per cent. of fuel compared with steam on the same en- zine.
 It is obvious, if this claim can be support ed, that bisulphide introduces now era in ocean navigation, as fuel becomes compare lively small item of expense, cargo space is saved, and steamers are relieved of the enor- nous weight of coal tonnage. On locomo- tives, too the change introduced is almost as radical, as tenders will be abolished they will be no longer necessary appendage. The in- significant amount of 100 pounds will propel sixteen -horse-power-engine and as the cost of blsuiphIde IS now about ten cents per pound Git can be manufactured for three cents), and as 1t IS used over and over, the introduction of the new giant motor must necessarily mean a sweeping revolution of 8 character more radical and far-reaching than can well be in- agined.
 The thew power of chemical vapor" is ex- hibited at No. BOT Eleventh avenue, and, &C., cording to Engineers Oh arles H. Haswell, Ed win D. Brady and others, has been subject ed to thorough practical tests with most prom l ising results. Mir. Brady says 'the days of steam are nearly numbered" ;" of which more will be known very soon.
