A NEW ARIZONA PRODUCT

Phoenix. July 18.-A new Ari.
zona product. made in Phoenix
and utilizing Arizona copper ex.
clusively in its manufacture,
was formally launched yesterday
with announcement that the
Shelf Water Cooler company
would begin distribution of alnew
type of refrigerator watercooling
system throug hout the state next
week.
Invented and patented by three
local men. the refrigerator shelf
water cooler is already in pro.
duction in Phoenix plant. AL.
though its initial output will be
for the Arizona market. plans
already are under way for its
subseq quent introduce through.
out the country. with possibil.
tiles that it will become an i'm.
portant outlet for the states
| famous metal.
Details of the new invention
and plans for its manufacture
were revealed for the first time
yesterday by officials of the
Shelf Water Cooler company,
following its incorporation last
Saturday. Otto Schopp Is pre-.
sident. A. F. Morairty vice. pre-
sident and general manager, Sam
F. Whitten secretary and Ed.
ward 81. Coe treasurer.
Arrangements to begin man.
ufacture of the cooler on q com.
mercial scale followed fifteen
months of experimental work
and tests, Mr.. Morairty said.
Tests were conducted not only
with experimental and demon.
stration models in use in Pboe-
nix homes, but ia laboratories of
electrical refrigerator manufac.
turers. with the result that en-
gineers Of the General Electric
company have pronounced the
shelf-cooler the most efficient
method of cooling drinking water
that has been devised for refri.
gerator use.
The cooler is extremely simple
Of construction. It consists only
of nearly -solid shelf made Of
lengths of e-eights' inch cop.
per tubing. The shelf takes the
place of any refrigerator shelf.
without additional space, aud the
water ia the copper tubes is COOL
ed automatically to standard re-.
frigerator temperature. Smaller
copper tubing provides an easily
installed connection with any
household water line, and an
outlet through a faucet on the
exterior of the refrigerator. The
complere system is so designed
that these connections may be
made without drilling holes ia
! the refrigerator walls.
In this way. Mr.. Morairty ex.
planned the cooler shelf provides
. constant supply of chilled, but
not iced, drinking water always
on tap, eliminates constant open
Jog and closing of refrigerator
doors and consequent impair
ment of refrigerator efficiency.
and removes the necessity OF
either occupying needed refrige.
rator space for water containers
or using uneconomical quantities
Of ice cubes.
Models of the shelf, it was an.
nounced. are being made for all
standard types of electrical re.
frigerators. and will be handled
by refrigerator dealers in all
parts of the state. The shelf is
virtually everlasting. since it is
made entirely of copper and
brass. This also guarantees pur.
ity of water.
10 the joint interests Of de.
veloping new industry and
new outlet for copper. designers
Of the shelf have had close CO.
operation Of the Arizona Iudus,
trial Congress throughout the
experimental and perfecting
period. The potential consump.
ton of copper alone ia OF real in.
terest to this state, congress Of.
ficials said. because one ton Of
copper is required for the man
ufscture Of every 100 cooler
shelves. and every refrigerator
manufactured or already in use
is an eventual prospect for
cooler.
