IMPROVEMENT IN ACTUATING ENGINES BY BlSULPHURET OF CARBON.

Specification-forming part of Lettcrs Patent No. 1|,553, dated August 22, 1854.

Totall whom it in ay concern:

Be it known that I, BERNARD HUGHES, of

the city of Rochester,in the State of New York,;

A is a generator; G, a working-cylinder; D, a

condenser; E, a pump to transfer the-condensed article from the condenser to the generator,-

a'nd Fa conducting-pipe from the generator to the working-cylinder;

I fill a boiler of an ordinary steam-engine with this liquid and apply heat to the boiler and supply the material as fast as-it evaporates bya pump; or Lfill the boiler partly full of water and eitherinject the bisulphuret of carbon into the water heated to any temperain re above 108 or I inject the bisulphuret of carbon into the vapor of water. The vapor of the bisulphuret of carbon operates precisely as steam, for which, in fact, it is a substitute; but as, on account ofthe'cost of the material which I use, it is important that itshould not be lost after it has once exerted its efi'ect, I make use of any known means of producing a perfect condensation of the vapor after it has passed through the cylinder and performed" its work to enable me to use the material over again.

The advantages of using the vapor of the bisulphuret of carbon as a motive power areas follows:

' First, it boils ata temperature of 108,while water bolls at 212, and my experiments have led me to conclude that at a temperature of 212 the'exp'ansive power of the vapor of the bisulphu-ret of carbon is double that of water.

Second, when water passes into a state of vapor at a temperature of 212 Fahrenheit 1,000 of heat become latent in the vapor.- I have ascertained byjmy experiments that when the bisulphuret of carbon passes into a state or vapor at a temperature of 108 only 144 of heat becomev latent. Therefore, by using the vapor'of the bisulphuret of carbon as a motive power a saving of fuel is efi'ected proportionate to the difference between the quantity of heat which becomes latent inthe-va'por of waterand-the vapor of the bisulphuret of carbon.

Third, itis known that in avcondensing-enginenearl y one-third of the power is expended in pumping the water for the condensation of the, steam. phuret of carbon I am enabled to dispense with about eight-ninths of the quantity of water ordinarily used for condensingsteam.

What I claim as my iuventiomand desire to secure by Letters Patent, isp The application of bisulphuret of carbon to any convenient form of the steam-engine as a motive power, substantially as described,when the vaporof said substance, after it has passed through the cylinder, is condensed by any known means of producing condensation'in a suitable reservoir and preserved for. the future supply of the boiler,substantially as above described.

By'using the vapor of the bisul-
