happen, because the fire is removed to a distance
of five feet from the bottom OF The cylinders, ana
the fuel used is anthracite. Wedon't want Il
because we operate simply by radiated heat. We
might make the bottom OF the cylinders red hot, but
the most common trouble is that they cannot be
made hot enough. There is radical difference be-
tween the Caloric Engine and the steam engine IN
this respect. The action of heat upon our cylin-
ders produces no i'll effects, and it Is only necessa-
ny to replace the furnace when it shall become UNI
fit for use-though that contingency occurs but
rarely; whereas, in the steam engine, in four years
the boiler is destroyed, and must be entirely re-
placed. Nothing of this kind being required IN
this engine-there being no boiler to be conoded
the saving is very great, perhaps $780, 600 to S40,-
900 every four years, in a large ship. have bull.
several engines since 1 startad the plan of this. and
have known some of them to last for years without
a renewal of the furnaces.
Q. What is the thickness of the bottom OF the
cylinder? 80
A. One and a half inches.
@. DO you, find no trouble from oxidation?
A. None whatever. There is a slight red oxide
formed; but it is so slight as to be of no trouble
The oxygen is all consumed in the fire, and no
residuum is left to occasion oxidation of the cyin-
dcrs.
Q. Could wood be used to fire the furnaces, as
in he vessels navigating the Mississippi river?
A. Wood would hardly answer; it would con-
sumo too quickly, and the boats would be obliged
to fall back upon coal.
Q. What amount Of coal do you consume per
dayi
A. On an average, from five to six tons; it would
be almost impossible to consume more than six
tons. The steamships consume 40 to so tons dai-
ly. There is accordingly a great saving here.
z. What is your opinion of coke as a fuelf
A. 1t would answer admirably.
Q. Does the extent of the power depend upon
the degree of heat or the size of the cylinder, or are
both :ndifferently increased? BE..t
A. We increase the size OF the cylinder TO OBJ
tain an augmentation of heat.
Q. How high is the power of this vessel?
A. About 600 horsepower.
Q. Can the power be applied to small machines?
A. Undoubtedly. l made a machine 4 foot i'll
diameter which ran with half horse power. The
principle is CT easy application.
Q. In what ratio does the increase of the diam
eter of the cylinder increase the power?
A. Just the same as the increased area Of the
piston.
Q. Are you perfectly satisfied with this trip MS a
first trial.
a. 1t has exceeded my highest anticipations.-
With the low pressure which, is now employed, The
engine has already effected more than / had any
reason to anticipate. [Cheers.l
Q. In regard to the amount of friction: what is
A. The amount of friction is less than that OF
any other engine.
Q. What amount of pressure is required to com
mence OpeTationS?
A. So little that a hall-pouni pressure to the
square inch is sufficient to give motion to the
whole.
q. What is the number of valves?
A. Thirty-six in each piston.
Q. Is it any cheaper to run at a moderate rate 4
speed?
A. 1t is somewhat so; the amount of resistance
of the water being as the square of the velocity.
Q. Is there any difficulty in keeping the piston
valves in order!
A.-None. If anything gets out of order,
there is a man-hole in the top of the supply-cyl-
inder, so that n man goes i'll with a light, looks
:.bout, remedies the evil, comes out, and shuts the
door behind him-.and there is an end Of it
lLaughter.l In the steam engine, on the contrary
whenever the valves are deranged, we must take
off the head, weighing some five tons-then wait
three hours for the engine to cool. Not SO here.
Q.-,How long a time do you take to pump in the
air for starting?
A very few minutes.
Q.-What would happen If the engines were
neglected. .
A.-The worst would be that the machinery
would stop.
Q.-How long since did this idea occur to YOU?
Alt has been cherished for twenty years. In
1888, l brought out in London my first model Ca
loric Engine, which ran with FIVE horse power; and
since that time l have built twelve or thirteen such
machines.
Q.-Do you emember the name of the British
Reviewer who commented fayotably upon your
invention about that time?
A.-Nearly all the English mechanical journals
of the day discussed the subject. Professor Fara-
enterprises lavorably. When the subject was first
agitated, it was denounced as involving among
other things, the ''chimera OF perpetual notion
but experiments caused some of these doubts to be
removed. Mr.. Faraday was much interested, and
lectured upon the new principle before crowded
audiences at the Royal Institute.
For nearly twenty years, therefore, l have pom
dered on this invention. During all this time, /
haze neuer been at a loss for means, (applause) and
on teaching New York and making representations
10 our capitalists, | met with a number of mer-
chants, supported by other gentlemen of capital,
who afforded me ample opportunity of testing the
Caloric principle on this large scale. (Cheers.)
The thing is accomplished; there is no remaining
difficulty in the way, which cannot be met; there
is no remaining difficulty in the way, which cannot
be answered. The principle has been tested long
enough to prove that it is reliable, feasible and sue
~cessful. (Cheers.)
Q.-Will you state what is the relative cost of
the Caloric ship and steamships
A.-The cost will be about two-thirds that OF
the steamships; that is, there will be a saving of
one-third in expense.
Q.-What is the ratio of expense as regards the
employmentof engineers and firemen?
About in tbe proportion of 1 to 5.
This ended the explanations and their accompa
nying colloquies.
