The Pacific commercial advertiser. [volume] (Honolulu, Hawaiian Islands) 1856-1888, 1857-09-17

We have been aware for some time past that Pr5
Solomon was engaged in our city constructing
patent g Sulph. Oil Carbonic Acid Engine, - and I'll
his prospects of success were highly encouraged
More than ten years has the Professor labored M
this favorite theme of his mechanical and seized !
genius, occasionally eneountering difficulties, but
close application and unbending enterprise, he fnalt
found his efforts crowned with abundant success.
We called yesterday afternoon, much to our graft
fcation. and saw the engine in full, successful opera
ton, several days, in Cypress alley, between Prattl
and Lombard streets This engine, being merely a!
model, or experimental one, has, of course, some irnl}
projections, and may be greatly improved, but it II
calculated for four-horse power, being a common rec
tilineal or reciprocatiDg steem-engine, differing in no
material feature from those In general use. The
patent novelty consists in the motive power and is
application, which wholly supersedes steam. This
metor is produced by a compound Of de. sulphiated
bi. s~ulphuret of carbon, coal tar and volatile or fixed
oil, which, under certain influences of heat, becomes
powerfully expansive, and thus gives momentum.
Though only a four-horse engine, it was performing
the estimated duty of ten horses, and has been so
doing since put into operation, nearly a fortnight ago.
The fluid, or gas, constituting the motive power. Is
used over and over again with scarcely any diminu-,
ton sa-Easte@ aEp. after performing its
condenser to the hea er again, with thorough renova-
ton. The heater where the gas or fluid is introduced
is submerged in a cistern of heated oil, kept hot by a
gentle fire. In this condition the gas expands.
gaining its power, and passing through pipes and
valves, and acts upon the piston, giving motion 10
the engine. The appliances are simple, easy of COM
prehension, free from complication, and not subject
to accident or disarrangement. Thus q steady. active
force is Mt all times kept up.
The cost of this fluid is estimated at ten cents per
1llon, and - is demonstrated that eighteen gallons.
by careful attention, viii run an engine of the
capacity here noticed for one year. Its components
are such as not to freeze even at ninety degrees
below zero. The amount of fuel is in proportion of
fifteen pounds OF coal to one hundred pounds. COM
pared with a steam engine of the same dimensions.
whilst more than double the force can be brought
into requisition. The engine, which we saw in opera
ton has a piston of twelve inches stroke, crank six
inches. 1t was doing the service of ten horse power
under break of a wheel 8 feet in diameter, 8 feet III
1-2 inches in circumference, pressed between two
bars, one on each side, and a friction block on each
bar of Z IL inches in length and2 IA inches In width.
on an iron rim of 2 IL inches, under q weight of 1l2
pounds, making 80 revolutions per minute.
To those versed in mechanics this will indicate the
engines capacity, or the power applied thereto by
this wonderful agency. The heat causing the result
here noticed was only 236 fahrenheit, or go pounds
working power under exhaustion, and an atmospheric
pressure of 10 pounds adverse, which adds that miich
to the active agent. BY trial with steam in the
same proportions, under a similar condition, with
261 degrees of heat, the amount of pressure was onlv
70 pounds to the square inch, and when tested the
engine moved but slightly and stopped. Thus there
is clearly demonstrated an almost incredible superi
GRITTY, or advantage, of this new motor, in its applica-
ton over steam. Besides the advantages above
noticed, we are told-and in Iced, it becomes ap-
parent to practical or scientific observer-that
explosion is impossible, and thus a momentous point
is gained in obviating all danger.
Professor Solomon was born In Prussia, and has
been a citizen of the United States over twenty-seyen
years.
