The Duluth rip-saw. [volume] (Duluth, Minn.) 1917-19??, 1918-07-13

MI. COuu IL. AlIcII, Dcdu VI CuC
department Of engineering in the
University of Minnesota, visited
Duluth and was taken through
the new building at Lester Park.
While the architecture Of the
building and its arrangement re-
ceived favorable comment, Dean
Allen remarked that the ventila-
ton system was "like that of
sawmill.''
This remark came to certain
members Of the board of educa-
ton with the result that a mo-
ton was passed, commanding
Messrs. Croft & Boerner, the Of
fetal architects, to inspect the
building and report on the heat
ing and ventilation systems.
''Let the tail 60 with the hide"
exclaimed director LeDuc. en-
clude the Morgan Park and Stowe
schools"
''Put in the Munger school
while you are about it," said d.
rector Proved. 1t was so voted.
At the last meeting Of the
board of education Messrs. Croft
& Boerner delivered their formal
report. Some of the directors pro-
fessed not to have read it and
time to read it at the meeting
publicly was not taken. By COM
mon consent the report was re-
ferred to the proper committee
and formal consideration Of
the matter will be given at the
next regular meeting Of The
board.
In presenting their written re-
port Messrs Croft & Boerner in
an accompanying letter Of expla-
nation said, viz:
"In preparation of the fol-
lowing report the assumption has
been that the board Of education
had two objects in view in order
ing this investigation, viz:
"First-That the board may
be able to correct any existing
defects that seriously interfere
with the proper and economical
operation Of their heating and
ventilating equipment.
"Second-That any serious de-
fects be recognized as such and
precautions be taken to prevent
a repetition Of such details in
any new buildings in the future.
"Care has been taken, there
fore, that the accompanying re-
port contains criticism of de-
fects Of real Importance only.
The report is free from criticism
of trade appliances Of particu-
lar manufacture. No mention is
made Of details of designs upon
which there is a difference of
opinion among engineering ex-
perts. The question Of high or
low pressure steam plants does
not enter into this report.
"Mr. John R. Allen, Dean of
the College Of Engineering and
Architecture, University of Min
nesota, has been consulted on
every point Of criticism included
in this report. Mr.. Allen has
shown real and personal inter-
est in the efforts of the board Of
education towards getting heat
ing and ventilation plants of
proper design.
"NIr. Allen is considered one
of the foremost authorities on the
subject of ventilation and heating
in the United States. His posi-
ton at the head of one Of the
most important departments our
state university places Mr.. Allen
where his opinion is , entirely
unbiased, and, therefore, of great
value"
The formal report was as fol-
lows, viz:
LESTER PARK SCHOOL.
Heating-In general, the heating
equipment of this school is installed
according to good engineering prac-
ton, with the exception of the re-
n1oval of air from the radiators. The
system as installed has an all air
. line valve on each radiator connected
to a pipe line that discharges into
the chimney. An air pump should
be installed On this air line. The cir
culation of the entire system would
be greatly improved and more even
heating secured.
Ventilation-The open area for
passage of cold air through the heat
ing coils is 1874 square feet. The
fan has an operating capacity of H.
600 cubic feet per minute. This
means that the velocity of air
through the heating coils will be ap-
proximately $500 cubic feet per min
