INTERSTATE MODEL IS,
Bourbon Garage & Supply Com
pany of Paris has the new
est Type in Touring Car.

The Bourbon Garage & Supply Com
pany has just received the following
advanced information in regard to the
new Interstate touring car, Model 35.
Model 35 is fitted with a roomy fore
door body, which is the last work of
perfection in the body builders art.
The seating accommodations are
ample, for a maximum of seven pas
sengers and the car is also designed to
be practical. and entiarely suitable for
a five passenger car alone. The two
removable and a UNSTABLE seats provid-
ed in the tonneau, are finished to
match the other upholstery. The up
holstering is of the highest quality of
hand-buffad leather, luXuriously tufted
and stuffed with genuine pulled and
curled hair. The finish throughout is
| the Interstate quality. which means
| the very best.
The power plant of the Model 35 is
of new design. In the larger and
more powerful motor Of Model ..35 we
have produced ell-balanced and
| symmetrical design by arranging the
inlet and exhaust valves on opposita
sides. The bearings in the new Model
35 motor are worthy of special men
tiOn. The main crank bearing is 9 in
diameter and d in length, (which are
very liberal proportions.
Mechanical description of Model 80
Interstate: Motor-The motor of
Model. 80 Interstate is of the T-head
type with valves on opposite sides and
develops fifty horsepower at normal
spee ed of 1900 revolutions per minute
the motor has bore of az and stroke
of 81. This form of motor construc-
tion gives fine accessibility to the
valves when it is necessary, as the
valves can be easily rotated by a brace
from above. In this method of arrang-
ing the valves on opposite sides Of the
motor. the tops of the cylinders are
not burdened with long rocker arms
and springs. which are demanded when
one or both valves are placed in the
head of the cylinders Moreover, plac.
ing the valves on both sides makes the
motor more accessible and the mani
folds and other auxiliaries being more
equally distributed on both sides of the
cylinder, there is better balance of
t lese parts. The valves are of extra
large size "a in diameter with Iickel-
steel heads and have carefully ground
stems. with removable valve guides.
The valves are operated by push rods
provided with frictionless rolling con-
facts on the cam shaft. making them
silent in operation. ihe rollers are
hard and thoroughly case hardened and
ground. A very advanced feature of
great practical worth in the motor of
Model 30 is the use of eccentric cam
and pump shaft bushlngs, thus allow
ing exact meshing of the timing gears.
The suspension Of the motor is by
means of three point support the ad-
vantageS of which are so we'll known
that it requires but little comment.
The three point support Obviates any
possibility of twisting stresses from
the frame being received by the motor
and supports the weight of the motor
more satisfactory than any other type
of suspension.
Crank shaft-Crank shafts are tmade
of a special alloy steel forging, heat
treated with the greatest of care and
machined and ground to exact diamen-
sions. Crank pin bearings are 7-8 in
diameter and 23 in length.
Cylinders-The cylinders are made
from specially selected close-grained
gray iron with integral water jackets
and valve chambers. The cylinders
are given severe hydraulic test after
machining and only those of. absolutely
fa@less construction are employed.
Strupul0usc are in the grinding of CYL
inders is carried out to prescribed and
accurate dimensions. Pistons and pins
ale constructed from specially selected
fine grained iron and are ground on
both sides and diameters and positive
ly inIs rchangeable. Extra large diam
eter piston pins are employed in the
pistons and these are carefully harden
ed and eound and of hollow design to
permit positive lubication.
Two complete ignition systems are
employed, the first consisting of set
of dry cells and a four unit vibrating
coil. The second of an imported high
tension magnetic. Each system IS
provided with separe te spark plug in
each cylinder, which are locat I'd in the
plugs over the valves.
LubricatiOn-The we'll Fworked out
and efficient Interstate forced fe ed
and splash system is employed in this
model. The gear driven supply pump
is of slightly different construction
than in the other models. 1t is of the
distributing type and provides positive
ana equal delivery tn the three .main
bearings. Oil Overfiows from these
bearings into the splash pockets of the
oil pan, allowing the splash spoons Jon
the connecting rods to dip slightly into
them and be distributed over the con-
Meeting rod and cam shaft bearings
and interior surfaces of the cylindars.
A sight feed conveniently located on
the dash and readily discernible, gives
positive information as to the condition
of oil supply.
Transmission and clutch-These are
OF unit construction but ssof larger di-
