The Public Test of ''Jumbo" Pump Wit

Il Grand Snccess-4nother to be Made at
Once-Eatters Connect ed scsth the Water-
tcOrIss System.
The city of Minneapolis has just cause
for oongratulation upon the successful
operation of Jumbo" the giant pump,
which was built for a 10, GOO, 900 galion-per-
diem-capacity. Yesterday afternoon
PUEBLO TEST
was given, which was witnessed by up
wards of 1000 interested citizens. The test
began by first shutting down
the other pumps, ard then
supplying the entire city with Mississippi
river products BY the revolutions of the
ponderous eccentric of Jumbo. The
pressure. or rather the consumption for
domestic purposes was insufficient to give
Jumbo" an opportunity to make the
number of revolutions per minute So
which it is contemplated to make and con-
sequently two three inch tups in the
pumps were opened and the water allowed
to flow back into the father of waters"
The pressure in making this test was about
sixty pounds to the square inch.
Then to show the amount Of water which
could be thrown through the giant
machine, tbs pump was allowed to fill
wheel pit which has just been excavated in
the new pump house. In no time, COM
was filled to running over and the pump
house flooded. The water thrown was at
the rate of 1n,5OO,0O0 gallons per day, or
500 gallons in excess of what was claimed.
practical fire test was then made. The
southern and central districts were shut off
by means Of closing the gates, and the
water allowed to be concentrated upon the
new 81 xteen inch main, which has just
been laid on First street, running north
from the pump house. This main sup
plies the entire northern district of the
city together with all the East side sys-
TEN.
The pressure was increased to 100
pounds to the square inch, and Jumbo"
ran at the rate of ninety eight revolutions
per minute. The bull dozer of the fire
department, being big two-inch nozzle,
was attached to the Thirty-first street
sixteen inch water main, while little
further on, at another hydrant, was at
tached fonr strings of hose with 1 IA inch
nozzels. Old Jumbo got down to work and
the bull dozer stream was thrown
200 FEET IN THE AIR,
stream which must have drowned out al
most any confagra!ion, and in few min
utes little river went coursing
down the street and down
the river bank to the bosom of
the Mississippi. This feat was considered
wonderful by all who witnessed it. Among
the spectators were Mayor Ames, the board
Of water commissioners, the city council,
members Of the faculty of the state uni
Yersity, scientists and engineers from
abroad, the officers of the fire department.,
millers, merchants and all classes of bust
ness men and prominent property owners.
By all, Jumbo was pronounced signal
success.
THE INVENTION.
The GLOBE has hitherto given it's read
ers detailed description of the pump.
In fact it was the first paper to give de-
iption-thereby evincing its usual en-
terprise in giving to its readers in advance
of contemporaries such matters as are of
unusual pablo Importance. Consequently
only few words respecting the invention
are necessary at the present time. Mr..
james Waters, the present chief engineer
OF the water works, was the inventor, and
Jumbo is the second pump manufactured
from the pattern-the first being a
100000 gallons capacity pump
now in successful operation in
Crookston. The cost was only
$500, whereas, had it been made of any
other design yet invented, it must have
cost the city at least five times the amount;
and not only that it occupies much less
space. All in all it is great economy to
the city, and furnishes the city, withel,
with the best possible fire protection
where the mains have been laid. During
the experiment Jumbo was almost noise
less except occasionally when the water
supply was insufficient. Then it jumped
and ran irregular. Give it an abundance
of drink--pun acqua, nothing stronger
and the smoothness with which it runs ia
wonder to the best machinists and
engineers.
TIE RESPONSIBILITY.
Mr.. Waters has secured a patent upon
his invention, but no royalty has been az
sessed the city. That is, Mr.. Waters does
receive cent in recognition Of his ingenu-
ity and skill in designing the machine.
This is owing to the fact that Mayor Ames
and the members of the board of water
commissioners, upon the representations
| Of Engineer Waters, took upon themselves
the responsibility OF ordering the pump,
| and taking all the chances as to whether it
must prove success or signal failure.
Now that Jumbo's efficiency has been es-
tablished beyond a shadow of doubt, the
water board, as we'll as the invention, are
justly entitled to the congratulations which
will doubtless be extended to them by a
grateful public-moIe than ordinarily
grateful after the blow struck by the
board of underwriters as our readers have
full occasion TO understand and to appre-
ciate through reading the comprehensive
reports of the recent prolonged and ex-
haustive investigation, prosecuted by the
committee from the board of trade.
ANOTHER PUMP.
A GLOBE representative had lengthy
conversation with Mayor Ames, who is
president of the board of water commits
sioners, upon the merits of Jumbo, last
evening. The mayor stated that the sue
| cess of Jumbo was beyond his expectation,
| although he acknowledged that
he had been confident that 1t must be
