relative value of coal and oil and that
MI. Burdtck in his report quoted the
price OF Pennsylvania lubricating oil
instead OF crude oil from the south
west
Mr.. Pogue also stated that his COM
pany was ready to stand back of the
proposition that it would pay $500 for
every gallon OF oil over so gallons
used to pump 100000 gallons of
water.
The council decided to lay the mat
ter over until City Engineer Treichler's
report was handed in, and adjourned
until later I'm the week.
Superintendent Sharp made his re-
port TO the council yesterday after
noon. He favored a. the time the De
Laval company's bid. With more in
formation as TO the position OF the
commission and the understanding
that the Fulton Oil company will in
stall a De Laval reduction gear on
their pump IL demanded by the city,
he is now backing the crude oil engine.
Wants Two-Lift Pump.
In his report yesterday afternoon Mr..
Sharp gives as his objection to pur-
chasing a Cameron pump that the
specifications call for a two-stage CEN
trifugal pump and that all bidders ex-
cept the Cameron people bid on this
type. In making out the specifications,
he says, great care was exercised to
secure a type best suited TO the needs
Of Rock Island and one for a head of
23O feet to operate against. The best
pump experts advocate more than
one-stage pump when the head is more
than $50 feet" he said.
He makes the statement that the
Cameron pump works have not steam
installation of the type referred 10 in
the bid that has been in successful
operation for more than a year.
The bids of the De Laval Steam
Turbine company he stated. lis best,
as there is sufficient advantage TO
warrant the experience of the COM
pany in the large number of munich
pal installations, all but five of which
are not as large as this city is consid-
ering. Every pump this company has
installed is satisfactory.
The De Laval company was the
only one TO comply with the specifi-
cations in that the unit be tested in
the shops.
Under the heading of responsibility
the De Laval people build the entire
unit in their own shops, thus giving
the city the advantage because it can
not evade any responsibility if the
pump fails to do the work properly
Turbines and gears used by the De
Laval company are favored by Mr..
Sharp, who states that this is the
only company to submit specifications
on the gear.
THE duty of the De Laval is also
the highest offered by any other tur-
bine companies, guaranteeing capac-
ity of 1O2, 100000 foot pounds per
1000 pounds OF steam"
In the summary of the report, he
says: There seems to be a differ
ence of opinion as to whether the
pump TO be purchased or the Snow
pump used at present will be used as
the reserve unit IN this connection,
the Snow pump is greatly in need OF
repairs and is being operated at only
half its capacity. Repairs will have to
be made and this will mean that the
pump will be out of commission for a
week or more The new pump will be
put into service while the old pump
is being overhauled and will at once
become the main unit.
An electric motor driven unit" the
report says, lis entirely out of the
question, as the bid of the Peoples
Power company is too high.
AN oil engine unit has efficiency,
and tabulations taken from testimon-
iaIs received from different manufac-
turers, they are built for economy, are
II, m ha danand-
ed on equally as we'll as a steam unit.
However, at present l have no relia-
BILE data on this type OF transmission
of power for continuous service.
Price OF the De Laval pump is
$3.50, while that of the Cameron
unit is s6,Os5."
