Superseded.
We have been aware for some time past,
says the Baltimore Patriot, of 10Th June, that
Prof Salomon was engaged in our city con-
structing his patent "Sulph. Oil Carbonc Acid
Engine" and that his prospects Of success
were highly encouraging. He was aided in
this enterprise by some Of our most opulent
and intelligent citizens, who, seeing the ulti-
mate practicability of his invention, did not
hesitate to furnish means enabling him to
reach the desred-and we are happy to believe
fortunate consummation. More than ten
years has the professor laborcd upon this favor
itc theme of his mechanical and scientific &C.
MUS, occasionally encountering difficulties, but,
by close application and unbending enterprise,
he finally found his efforts crowned with abun-
dant success. That which to him appeared
certain in theory, consonant with mechanical
laws and philosophical principles, has, at last,
been outwrought and practically demonstrated
so far at least, as our judgement goes, after
seeing and judging for ourselves-admitting
not even of doubt as to its complete triumph.
We called yesterday afternoon, much to our
qualification, and saw the engine in full, sue
cessful operation, where it had been working,
without interruption, several days, in Cypress
alley, between Pratt and Lombard streets.
This engine being merely model, or expert
mental one, has, of course, some imperfec-
tons, and may be greatly improved, but it
worked with remarkable precision and regu-
larity. II is calculated for four horse power,
being common rectilenal or reciprocating
steam engine, differing in no material feature
from those in general use. The patent novel
ty, consists in the motive power and its appli-
cation, which wholly supercedes steam. This
motor is produced by a compound of de- sui
phatcd bi sulphuret of carbon, coal tar and
volatile or fixed oil, which, under certain inAu-
ences of heat, becomes powerfully expansive
and thus gives momentum. Though only a
four horse engine, it was performing the esti-
mated duty of ten horses, and has been SO
doing since put into operation, nearly fort
night ago.
The great virtues and triumph of this Won
derful invention, which, in all probability will
cause revolution in mechanics, are its econ
omy, safety and power, combining also cheap
ness and convenience.
The fluid, or gas, constituting the motive
power, is used over and over again with scarce
" any diminution of waste being shown, after
performing its work, from the heater to the con-
dcnser, and from the condenser TO the heater
again, with thorough renovation. The heater
where the gas or fluid is introduced, is sub
merged in cistern of heated oil, kept hot by
Gentle fire. In this condition the gas ex'
pands, gaining its power and passing through
pipes and valves, acts upon the piston, giving
motion to the engine The appliances are
simple, easy of comprehension, free from COM
pIication, and not subject to accident or dis
arrangement Thus a steady, active force Is
at all times kept up. nli"
The cost Of this fluid is estimated at ten
cents per gallon, and it is demonstrated that
eighteen gallons, BY careful attention, will run
an engine of the capacity here noticed, for one
