the Pathfinder Motor Sales Company,
11O North Second stret.
A twin six motor of unusual de-
sign is used by the Pathfinder Com
pany in their latest model, pathfinder
the Great" Around this multiple
cylinder motor every unit and working
part has ben carefully designed and
tested, over protracted period until
the Pathfinder Company is willing to
accept the judgment of the American
public on its latest effort. It's speed
range in righ is capable of doing 70
miles an hour and throttle down 20
two at will. Because of this speed
fiexibility, it would be entirely pos
sible for the ordinary driver to go from
New York to San Francisco in high
gear, If he cared to devote himself
to such an unusual undertaking. Even
on hills pathfinder the Great" it Is
said, has time and again succeeded
in accelerating in high after starting
from dead stop.
There has been a great deal of mis-
understanding so far as the term
multiple cylinder is concerned
Every one knows that so far as mere
utility goes, q four cylinder car will
do the work, but there is more to
motoring than mere utility. The
Pathfinder Company has long real
lied that the multiple cylinder type
solution to the vibration problem, that
is made by the lapse" or explosion
points of the lesser cylinder type mo-
tor, and has been experimenting on
this subject on constructive lines for
a number of years. These expert
ments led TO the adoption of the Path
finder twin six motor, as superior to
an eight.
The Pathfinder tNFelve-cylinder mo-
tor, by employing valve-in-head con-
struction does away with the draw
backs charged against the "V'' type
motor with al" head construction In
the az" head, valves must be placed
either inside the "V" or outside. The
entrance to the angle of the "V'' is
obstructed by placing valves inside,
making adjustment of carburetor,
valve tappets, etc, extremely difficult
and unhandy. BY placing the valves
outside the "V," the motor requires
increased hood room without increas-
ed power or efficiency.
The cylinders of the Pathfinder
twelve are cast in blocks of three, with
motor head, intake manifold, and wa
ter outlet integral for each set of six
Block castings maintain q more per-
feet bearing alignment due to in
creased rigidity of the crankcase. To
permit connecting rod bearings to be
side by side on the same crankshaft
pin, the right set of cylinders sit 4
inches forward of the left. The stroke
is 2B inches with a 5-inch bore.
The twelve cylinder ignition prob
lem is solved by the Pathfinder igni-
ton system giving extreme simplicity,
eliminating the vibrator and assuring
constant supply of current The
current for ignition is supplied by the
motor generator with a strong bat
terry floating in line. A single igni-
tion timer and distributor unit con-
tains a separate circuit breaker and
distributor for each set of six cylind-
ers. These are operated from single
crankshaft speed from the camshaft,
resulting in perfect synchronization. A
centrifugal governor in the base of the
timer housing automatically regulates
the spark advance for normal running.
A hand advance is supplementary for
extreme conditions.
Pathfinder the Great" has a vir-
tue which is demonstrated to a re-
markable degree, namely, its wonder
full smoothness. Its power is gene
rated with such oily regularity that
there is no suddenness in its action
in face of the fact that it is by actual
demonstrations one of the fastest ac-
celebrating cars built. It's balance has
been perfected so that even at 70 miles
an hour, not a passenger has any
sensation of extreme speed.
