of preparations for the Iowa exhibit o
machinery at the st. Louis exposition i:
gratifying to the manufacturers of tn
state. This department was placed II
charge of S. NJ. Leach, of Dallas coun.
ty. the member of the commission fol
| this district. and he has named A. c
| HutChins. formerly county superintend-
ent of schools OF Dallas county, to have
charge of this work. They have al
ready had considerable correspondence
| III reference to the matter and the
signiiied that they are willing TO do the
right thing. Thomas NJ. Moore chief
OF the machinery department, is urging
| that Iowa make fine display of ma
chinery to dispel the prevailing notion
that this is purely an agricultural state
Mr. Moore has written Mr.. Leach as
| follows:
You will doubtless he glad to learn
that we have practically decided to ac-
Cept an Iowab built steam engine as one
OF the prime movers in our great ev-
position power plant a few days since
| L completed arrangements with the
Murray Iron Works, OF Burlington. TO
accept one OF their 500 II. p. heavy
DUTY, Corliss type steam engines. l ex-
pect to directly couple to this Il
Croker Wheeler generator, and this
generating wet will be one of five items
which will operate our Irtramural rail-
way system. The character and terri
torial distribution of the states from
which these items are drawn seems to
be quite interesting. Ore steam en-
gine of 600 II. p. is the product of the
Harrisburg Foundry AID Machine
Company. of Harrisburg. Pa. A second
steam engine. of 700 II. p. is the prod
uct of the Lane & Bodley Company. of
Cincinnati, Ohio. A thi:,,. of 500 II. p.
is the product of the Murray Iron
Works, of Burlington, Iowa. gas en-
CINE. of $500 II. r.. Is the produc. of A.
Borsig. ui 80, aC-g E.s.i... Germany.
and the gas producer for the operation
CT this engine is the product Of Julius
Pintsch. of Berlin, Germany A tan
genital water wheel of 300 II. P. rating
is the product OF the Abner Doble Com
pany. of San Francisco, Cal. and the
artificial head to operate this water
wheel will probably be effected by n
centrifugal pump directly driven by d
steam turbine built in Stockholm,
Sweden. and the water will be meas
ured by meter built by the Builders
Iron Foundry, Providence, r. |. The
generators will be the product of the
Crocker- Wheeler COMPANY, of Ampere.
\. j.. and the switchboard will proba
bly, come from Boston. Mass. All of
these items will be assembled on one
large space, where also an opportunity
Will be given to each of tie constituent
exhibitors to install an office adjacent
to their exhibits.
.'The total load. you will observe. will
be $500 II. p, with capacity for tenn
porary overload of % PER cent add-
tional. Save in very MINOR instances,
we do not expect TO generate any 500
volt direct current except by this COM
for the operation of our 1ntra-
mural railway (Which. by the way, will
be about seven miles long. and possibly
+. may reach to nine mites. all, how
ever, within the fences IF the EXPOSE
tion)
The total power generated and used
by the exposition will be in the neigh
borhood of $4,000 H. p. A relatively
small percentage of this, as above
stated. would be 500 volt direct current
A still smaller proportion Of this will
be 2.400 volt three phase, fifty cycle al
ternating current, and very minor items
will give us a 40 and 900 volt current,
but over so per cent of the electric en-
ergy which we will avail of will be in
$500 volt three-phase, twenty five
cycle current. Without at the present
hurdening you with the details of the
various constituent parts of this great
power plant, l think 1t will crafty you
to learn that the largest unit will be an
z, 900 II. p. steam turbine, and the next
largest a 5000 III. P. compound horizon
tai and vertical reciprocating steam en-
last named from Seraing.
We have come to talk of
of horse power so glibly and
easily that / think we hardly appreciate
that we have reached the limit possible
With the present carrying capacity of
our railways BY this I mean the ca
pacity and free passage room on and
thru railway bridges ard thru railway
Nevertheless, / think 1t is a
fact that not one person in a hundred
thousand ever has seen steam tur-
line of 5000 IL. p. capacity not one
person in ten thousand has ever seen a
steam engine of 5000 II. |
P capacity; and no one in the world
las ever seen n gas engine of 5000 II.
p. capacity. BY comparison With for
mer expositions the following facts ap-
pears: The largest steam engine
in the Chicago exposition was rated a,
:, 500 FL. p. and the largest gas engine
IN that exposition at ten II. p. The
largest steam engine in the Paris eX~
position of 1900 (Which. by the way,
was the largest steam engine ever eX-
hibited in any exposition up to this
time), was rated at 4,00n II. p. 1t will
thus be seen that we shoN steam en- |
CINE of over three times the power of
any shown in the Chicago exposition,
and over twice the power of any shown |
IN the Paris exposition, 81, in fact, in |
any exposition prior TO ;his time The |
with reference to gas en- |
rines is stll more impressive. Those
exhibited In Chicago were relatively |
mere toys. and the largest exhibited In
any exposition up to this time have |
been of 600 H. p. capacity as shown in |
the Paris exposition OF 1900 and the
exposition of 1902. From |
this 1t will appear that the 5000 III. r.
engine exceeds by five times the power
or any gas engine ever before publicly |
exhibited. AS matter OF fact, we Will
have several gas engines. each develop !
