Cold Water Safety Steam Engine.


We insert below n correct description of
this invention, given by Mr.. 1'ppell the in
ventor himself:-Cin. Dol. Weekly.
!. Il is denominnted the Cold water Safety
Steam Engine, because the steam is gene
rated 10y injections of cold water into heated
generators, without n boiler, aud converted
into highly rarified steam instantaneously,
which acts Immediately on the piston in the
working cylinder, ms in the ordinary manner.
2. The generators are formed by putting
one cylinder within another, TO create two
highly heated surfaces within the distance of
one. sixteenth Of an inch apart. AT the low
er end Of the external cylinder there is nt-
tnched large solid block of iron, which
may be round or square, about eighteen or
twenty inches long, standing ut right angles
TO the external cylinder, called the foot of
the generator. About the middle of this
is placed tube, very thick and strong, com
municating with Il hole in the foot, which
leads to the space or surince between the
Two cylinders. This tube is the charge to
receive the water MS il is injected. This foot
and tube is the only part in the fire, which
is kept very hot, aud made very thick to pre-
vent burning out, and TO maintain an mex
haustihle fund of heat, so that the quantity
of water required at every stroke of the pis-
ton shall not cool il down below 400 degrees
of heat for high steam; il mny be as nigh
MS Goo, or as low ns 2l2, but the power of
the engine will vary in proportion.
There nre Two generators required TO con-
stirute one engine; they stand vertically in
an iron frame, resting upon brick founda-
ton, with the feet thereof so arranged in the
| fire us to become equally heated. The heat

through the internal cylinders, aud around
the external cylinders, heating both surfaces
to high degree.
On the top Of these tubes sits the injection
valves, SO constructed as to measure the wa
ter u, every stroke Of the piston, according
10 the velocity of the engine, e, If she runs
fnst, less water is injected; if slowly, more
is is injected. This forms complete gov
ernor, and regulates the speed. The water,
when so INJECTED, is Immediately closed in
the charger, by M action OF the valve which
can never fail il well built; (; this is by the
intense heat OF the foot driven Immediately
| into tho thin space between the two cylin-
| ders forming the heated surface, where il is
| insiantaneously converted into steam.
| Near the top of these generators nre two
tubes, standing out from tho furnace at right
angles, upon these are bolied fast the work
ing cylinders, in a horizontal position, to
which is attached the machinery, MS in the
ordinary engine by double crank. The
steam enters the working cylinder at this
point through tho tubes, driving the piston
ont, and escapes, leaving nothing behind to
cause an explosion or the least danger.
Now let us examine this principle in n
philosophical manner; much has been said
about it and various are the opinions based
upon sound scientific principles, and perfect.
ly practicable; il is an invention Of greaI
magnitude, and should he examined without
prejudice. That it absolutely runs and quite
t regularly, keeping mp the heat at the samt
time is not denied. The question ther
stands is il as commendable, and ns power
fiil as the ordinary engine, if 50, Eyicsso,
mny quit, aud the Queen City has beatel
: New York.
: The inventor to prove this fact, demon
e strales the principle of the old engine times
:. For example, he shows that there must be q
much water injected into the boier, as
evaporated into steam, and passed off lhroug
Q the working cylinder. by this, he show
TINT IL TINT water was converted into stenI
without a boiler, instantaneously, and con
PEELED 10 force its existence into the cylindt
by the departure of the piston, the power
wonld he The same, aud much greater If Ill
heat wns greater, as in his engine there is n
} spnce or vacuum for the steam TO form i
l. existence hut in The working cylinder.
!. Now this is perfectly consistent with Il
laws OF nature and is sound reason. 1T
water is measured at every stroke of ii
u piston by an equal pressure, by It's specif
o gravity and according TO the time. The val'
