After seven years of untiring effort
perfecting an aluminium automobile
motor, Earl G. Gum, chief engineer
Of the Premier Motors corporations
of indianapolis, has earned a rest.
lie chose the southwest of this great
country and win be a Phoenix visitor
Tor a few days in the near future.
For five years Mr.. Gum was with
the Northway Motor and Manufacture
ing company of Detroit During this
time ne had the bee in his bonnet"
that the logical automobile motor
was one constructed of aluminium
Gum held fast to his idea and ard
entity overeame, one by one, all the
obstacles
With what he decided was the
correct principle in the construction
uf an internal combustion engine
built of aluminium he induced his
company to build fifty motors all
Of which We're identical in appear
ahee-even being painted exactly like
the ordinary iron motors that were
being produced
These fifty aluminium motors were
the ba sis of experimentation upon
which Gum hoped to prove his ideas
correct. They were shipped to a GER
tain motor car builder without his
edge-their numbers carefully

owners watched with patient inter

builders have yet to hear complaint
from any of those fifty original
aluminium motors.
Material is Sensitive
Aluminium IS sensitive metal
subject to great variations owing to
heat expansion and only Mr.. Gums
great engineering ability made it
possible to overcome this great factor
thar seemed TO make the aluminium
motor impractical.
When asked if the alkali waters of
the west would seriously injure the |
aluminus motor in the Premier. Mr.. |
Gum said
When l first heard this criticism. !

to me a barrel of strong alkali water |
from Dakota and this water was all

this day the motor runs as smoothly |
as ever and its cooling qualities are |
as perfect IS the day the motor left |

heard OF them giving any trouble? |
That's the answer. But 20 insure /

the Premier aluminium motor are /

heat, cold, acid or alkalis. This ma

Begins the Work
When the Premier Motors cor
poration was being organized to take
over the name and good will of the
old Premier manufacturers, the ques-
ton of mechanical construction ma
turally developed and I was called
into conference ON the subject, of an
aluminium motor and after many
meetings, I accepted >he position as
chief engineer and went to work
The Premier aluminium six as ii
stands today is the product Of Mr..
Gums initiative and ingenuity and
TO him must he accredited the first
successful aluminium automobile mo-

duced YOU can bet is O. K. and that
Phoenix and Arizona will show its
appreciation by making the Premier

gear shift-the real premier of motor
cars
