| posed very nearly if not exactly to balance each
other. But the experiments alluded to indicate very
decided increase Of volume, provided there is sufi
cicnt difference of temperature. If pure Transparent
steam be mingled with air previously heated to the
degree, none Of this expansion il experienced
and il becomes question how to compress air in
pump and convey it in cold state into heated
cylinder.
Mr. Storms avoids the solution Of this difficult prob
lem by allowing the air to mix thoroughly with the
steam at any temperature it may ctauce 10 have,
cooling it aherward by expansion. In other words,
lie mixes hot Dir with the steam in the steam
chest and docs not expect the mixture to the
cloud form until it commences TO expand in the cyn-
der. The act Of expanding oools both steam and air,
but in very different proportions. Pure steam OF
high pressure SAY 60 ibs has temperature Of abou:
800 +. and if cut off at haIfstrske to double
its volume by expansion, cools down TO only about
go, while air at the temperature if expanded to
the same extent cools down to about the freezing
point. Thus the combined fluids may readily be com
peeled By expansion to assume tho form Of cloud or
SECULAR vapor if the essence Of air at different tenn
perature be the only conditicn necessary. To accom-
psh this object in ordinary horizontal engine, Mr.
Storms has in he instance abo referred to placed

il TO discharge into the steam-cbest just above the
valve As the first portion Of the stroke Of the pump
is spent in simply COMPRISING its contents it is
timed that it will begin to deliver with the
mencement Of the stroke Of the piston. The pump is
enveeped in jacket Of cold water TO keep it cool,
and the air probably the stcam-chest at TOM

A series of experiments have been lately tried at
the Novelty Works on q toeraby large scale The
engine was run first with steam alone, and thea with
the cloud combination, the resistance being constant
in all cases. The revolutions produced per ib of coal
were as follows: Steam lo7, cloud 100; showing
great advantage by the Use of the cloud vapor.

SarKTf-Tnucx Mr. Caleb II. Disbrow of Bath,
Steubtn County, in this State, is the inventor OF
very desirable improvement in car construction, of
which the above is the verbose and somewhat terrific
cognomen. The term broken frame, suggestive Of
anything but safety to the unintated refers to the
fact that the franc is divided ongitudnsIy in the
middle, and only connected by an extra axle run
ping across the cenier-a construction which allows
each half to oscillate vertically without efecting the
other and enables the car TO ride all the ord-
aIy inequalities of the road with seadrcss prcv-
ously believed to be unattainable. A "cabooss"
car, running on the Buffalo, Corning and Newly
Railroad was lately fitted with this Improvement and
its prac,icabiity perfectly demonstrated the be-
ing found to run with such steadiness that writing
could be executed in very tolersbe manner in its
interior even at high veoctes. There are four
wheels in each truck, arranged in their usual positions
but the axes are dvioed in the middle, to allow
each wheel to turn independently of its mate, thus
overcoming the tendency 10 twist and fracture the
axle and TO grind the langes against the rails in turn
Ing curves on the road. Each truck is necessarily
provided with an extra axle (which may be very
cheapy fitted as there is but very little notion and
four extra boxes or bearings.
BAncocKs PRESS FOR PRINTING CoLoRs.-Messrs.
A. NJ. Il G. II. Babcock of Westerly, II. l., patented
in October last and have exhibition at No %
Beekman-st a style Of press which prints in three
colors with perfect register and with the attendance
of but ono boy executes in three colors 900
sheets per hour in the finest style of the art. The
press now IN operation is capable of printing forms
by inches but another is in process of construction
designed to print colors which is to be super-royal
size, or capable Of printing form 90 By % inches
Tie number of colors may on either of these presses
be increased by blending printing one upon anoh-
cr method of producing variety which is now fire.
quently employed.
The press now in use may be briefly described as
follows: Imagine square cylinder lparallelopipedon
is too compound word to pronounce) mounted on
horizontal axis and turning quarter of q revolution
after each impression. Imagine three forms of type,
each mixed with different color, approaching stimuli
taneously against the side and bottom faces while the
hands of the operator employed in removing from
the upper face the finished article and supplying
clean sheet The impression being complete,
the forms recede and receive fresh charge of ink
from suitable rollers, while the "square cylinder
completes one-ourth of revolution. BY this means
each sheet of paper receives in turn the impression OF
the three forms and presens itself at the top to be re-
moved. The three simultaneous impressions arc OBJ
tanned from the partial rotation OF single SHAFT
which draws up the beds with gradually decreasing
velocity The strains this shafas also the CEN
trail er paper cylinder partially balance each other,
and the arrangement of the mixing apparatus, as also
of the whole Continuance indicates high degree OF
mechanical perfection The larger press alluded to will
be ON somewhat different plan covered, however, by
the same patent 1t will be provided with pentago-
nal instead of square cylinder, and will be sefecd
ing and selt-tyrg.
IMPROVEMENT IN Recommendations. Uhry x
Luttgens of Paterson, n j., have recently patented
an addition 10 the link motion, by which with the aid
of an extra valve and cylinder face great economy
in the use of steam is obtained One valve admits
and the other discharges the steam By this device
the wire draw effect of ins sufficient opening OF
the valves is entirely avoided and the compression OF
the exhaust steam which remains in the cylinder
toward the end of the stroke may be varied at pleasure
or reduced to nothing. The addition consists OF
another eccentric having the same motion as the
crank, and working by means of suitable rod PIN
or block which is free to slide up and down in light
