NEW START FOR THE CADILLAC
Motor Set Going by Electricity on the
New Cars.
DYNAMO SUPPLIES THE CURRENT
Electricity TO start Motor, Light the
Car and Perform other Unique
Service on the 1912
Models.

The usual policy Of the cadihAc Mo-
tor Car company to produce the ex-
ceptional brings out for 1912 car whose
motor is started and isnited. ane whose
lamps are lighted by electric current from
the same sources-a dynamo on the motor.
Never before in a gasoline car has
electricity been utilised 20 such an extent
The adoption Of the dynamo for ignition
supplants the usual magnetic The driver
has two complete ignition sources at his
oommand-the dynamo and the Deleo dis
tributor system, each with it's individual
set Of spark plugs.
The electrical plant consists Of q com
pact and powerful dynamo which lie oper-
ated by the engine and chargee a storage
battery.
To start the motor the operator simply |
rstards the spark lever and dlsensages the
clutch
When the clutch pedal is pushed for
ward, automatic engagement Is made be-
tween a gear on the dynamo and gear
teeth on the engine fly-wheel. The cur
rent from the storage battery operates
the dynamo. which becomes an electric
motor for the moment-and the engine is
turned over the same as il the operator
were in front of the car using the old
style crank.
As soon as the engine begins TO draw
in the gas from the carburetor and runs
on its own power, the operator releases
the pressure on the clutch pedal and i'm
mediately the motor gear dlsengages its
connection with the engine and the car Is
ready 70 be driven The dynamo then re-
sumes its function as a generator and it's
energy is devoted 10 ignition and to
charging the storage battery. This has a
capacity Of so ampere-hours. and as soon
Is that capacity is reached the charging
automatically ceases.
Practical Tests Satisfactory.
Practical tests have shown that the
storage battery is Of sufficient capacity
10 operate the starting device and turn
over" the engine for a space Of about
twenty minutes, although it seldom re-
quires more than a second or two to start
the engine. In fact, the Cadillac engine
50 frequently starts on the spark that
the use Of the electrical starter is not al
ways required.
The storage battery also supplies the
current for lighting, The car is equipped
with two specially designed electric head
lights. with adjustable lamps to focus the
rays properly-two front side lamps tail
lamps and speedometer lamp.
The dynamo also supplies current for
ignition. Up to $50 to 300 r. p. M. the
ignition current comes from the storage
battery, while above that speed It is direct
from the dynamo through the high tension
distributor TO the spark plugs. For igni-
ton purposes the dynamo performs not
only all the functions of the most highly
developed magnetic. but possess even
greater efficiency, having more flexibiity.
ana greater range Of action When
compelled TO drive slowly in crowded thor
oughfares, over very bad roads or on hills
with the usual magnetic the driver may
stall his motor, because the magnetic is
not driven fast enough to generate cur
rent, and 1t becomes necessary to switch
Tor tho battery, II he has one. With the
Cadillac system, IL II becomes necessary
10 drive so slowly that sufficient current
10 not generated, the battery automatically
SUITS in. When the speed is increased. the
dynamo again automatically takes hold
II wholly obvIates the necessity Of the
drivers keeping continually on the alert
TO prevent stalling the motor
Auxiliary Distribution.
In addition to this ignition, the Cad
lilac is provided with the auxiliary pelco
distributor system. This is separate and
distinct with its own set Of spark plugs,
and in itself is thoroughly efficient for
roaming the car entirely independent Of the
main system.
The entire electrical plant has been de-
signed with Q view to compactness and
efficiency, simplicity and positiveness; and
10 oovate, as far as possible, the neces-
sity Of attention.
The Cadillac company makes but one
type OF chassis, but offer a line OF six diff
terent types Of bodies. viz: Five-passenger
touring car, fouT-passenger phaeton and
tWo.passsngsr roadster. each 81 800; four.
passenger torpedo at $500; three-passen.
ger coupe at S225O ana seven.passenger
Limousine, at So $50
Other noteworthy improvements are
mads in the 1912 car. the more important
OF which are increased power, larger
wheels larger tires and larger brake
drums; increase in the gasoline capacity
OF all models and gasoline gauge on the
dash.
The size Of the cylinders is not in
creased. but the increase of power
10 gained in other ways, For instance, the
valve openings are larger, the intake man
Hold Is larger and the shape changed to
insure more uniform distribution OF the
gas to the cylinders and new carbure-
tor. OF Cadillac design, IL developed in the
Caalllae laboratories, is used. Not only
does 1t simplify adjustments, but has maxi
mum efficiency and flexibility from low to
nigh speeds. The only adjustment to be
changed under varying conditions is the
air which Is controlled by a small lever
a. the steering wheel
In the transmission the front ana rear
drive shaft bearings are made oil tight
by the addition OF stuffing boxes
The rear axle is Of the same general
construction as 1911, with some improved
details the principal change being in the
brake and hub clutch. The rear huh will
be shorter, and the brakes are increased
from fourteen inches TO seventeen inches
IN diameteE' with an improvement in the
brake operating mechanism.
