Highways Are Held to Be
an Integral Part of Na
tion's System of Trans
portation.
That highways are an integral
part of our nation's system of trans
portation has been emphasized by the
war, an an enormous development is
at hand, so important as to require a
comprehensive national policy, under
which federal appropriations for
highways will be applied to national
needs for interstate colmmerce, agri
cultural, postal delivery, common de
fense and general welfare.
Congress should create a federal
highway commission, independent of
presenit departmients of the govern
ment, composed of members from
the different geographical sections
of the country, to perform all exec
utive functions of the federal gov
ernment pertaining to highways in-.
cluding tihose relating to existing
appDropriations in al.d of state coin
struction. Suich a coiimmission should
act in co-ordination with any federal
agency that may have functtions of
articelatiig rail, trolley, water and
highway transportatlion.
Congress shoultd make substantial
appro)priations for the construction
and maintenance of a national high
way system to serve the need for the
mtaintenance of interstate travel and
traffic.
Thle commtission should report to
congres;s a plan for continued aid for
statet construction of highways in the
period beyond 1921, to which time
the in ovisions of existing federal-aid
laws extend.
Expen.ditures; of funds should be
permitted only for highways which
are of a permanent type, having thor
ough drainage, subustantial founda
tions, soufficient width, and a tapac
ity for traffic which will be reason
ably adequmate for future needs.
Inspect Ball Bearings
Once Every Six Months
Few ownersV pay the attention to
the ball bearings that these latte
deserve. They usually wait until th
garage matn calls attention to the i
jury done by breakage. At least one
in six months ball bhearings shouldh
inspectedI, the rough or worn balls
replaced with perfect ones and the
ball rtun lilled with graphite grease.
Use of Heavier Grease
Stops Gear Case Leaks
If oil and grease drop out of gear
case or differential housing, the bolts
must lie set up more tightly, as it is
an expensive-job to replace all the
gaskets. If tightening the bolts doe
not stop the leak, then use a heavier
grease. one which will not thin out
so much in hot weather.
"CLUTCH RIDERS" LOSU"'.
POWER WHILE DRIVING
Slight Pressure Unconsci
ously Put on Clutch Pedal
Causes Unnecessary
Wear, It Is Said.
Are you a clutch rider? Does your
foot continually rest upon the pedal
controlling this ilmportant part of
your car? If so, you are uncon
sciously wasting power and are help
ing put the clutch into a condition
where it will slip permanently. Spend
a few minutes studying your clutch,
its makeup and principles on which
it works, learn how to keep it in con
dition and likewise learn to keep
your foot off thie pedal when it is not
required to be there and you need
never have any trouble from this de
vice.
Now about clutch riding. The man
who keeps his foot continuously on
the pedal exerts some pressure how
ever slight and though but weight
of the foot--which has a tendency to
release the spring tension and make
the clutch slip. Slipping is a waste of
plwer and there is a friction which
wears away the contact surfaces,
adiding all the while to the slipping
prolpisity. You should not act as
though fearing a need to release the
clutch all lthe tlime. With practice the
foot should go aultomatically into
place.
On some cars clutch riding will in
variably burn out the thrust bear
ing, due to the inechaniceal construc
tion. There are some other cars,
however, where a careful driver may
safely rest his foot on the pedal, if
prlessllure sufficient to release the
clutch is not exerted.
(Clutches are of two general types,
the cone and the multiple disk, the
latter' being either dry or running in
oil bath, conimonly called wet, and
this kind will not go dry on July 1 if
you carie anything about the power
of your car. The cone clutch usually
is lbuilt into thie fly-wheel, the inside
of the rim fonliing one of the fric
tion surfaces. Very often the wet
disk clutch is intergul with tihe crank
ease and its oil bath is a part of the
general oil supply :carried therein.
The purpose of the clutch is to
connect and disconnect the engine
and the rear (drive) wheels, so that
the engine may continue running
without driving the car and to re
lieve tihe load from the transmissidn
gears when they are shifted to the
various positions and speeds.
If the loud were not taken off the
gears when shifting it would be im
possible to make the shift in many
cases, and if the shift were by chance
effected there would be excessive
strain put oni the gears and very
likely teeth would be broken off.
When the load is off tile gears at the
time of the shift the teeth engage be
fore the load is applied. If it were
not so the full load would be on the
instant the gear teeth touched. Gears
are made to stand severe knocks and
strains, but teeth break with the best
of care and shifting under load would
leave few cornert's on the teeth.
All the clutthes in use, except
ptllp5i c10 IllagaleL , 111 ui 0 o
ion variety, that is, the power i
transtted y the friction of the
part, whc are held together with a
ptg. And all provide for the load
to picked up gradually.
If the clutch were positive in ac
tion, y the engagement of lugs o
erwisethe car speed at once
ol he that of the engine and i
wuld start off with a jerk, with all
its iscofrt and strain; it would
e te se as though there were no
clth itervning. And the clutcl
mst e kept in shape to allow this
gradual engagement. In a leather
faced cone clutch when the leather
ecomes h and the engagement i
sudden, you have a gripping clutch
and a jerky aclion.
T prevent and remedy this th
leather must e made soft by apply
ing netsfoot oil ior castor oil.
On the other hand, too much oi
will make the clutch slip, with th
resultant loss of power. Sometines
oil il ooze in from the engine o
transmission gear case and make th
leather greasy. On the road the hbes
tig t do is to shake in some
French chalk, tale or Fuller's earth
to aor tie excess oil and dry th
srfac. se it sparingly. In th
garage it is better to wipe off the
urac itlh k,'roselle -- glasolin
is t leather too nilleh.
Ieep Frei Flioim Oil.
The plates of the dry muitiple lisk
clutch usually are faced with asbes
tos. Usually there is an opening in
the bott(om of the clutch housing to
ermit any oil which works to from
ngine or transmission to drain off
instead of greasing the plates and
facings.
It is very important to keep these
free from oil for that will make tl
clutch slip, and if it be allowed to re
main too long may become sticky and
revent easy release of the plates. If
they blxgin to slip and are found free
fromi oil it may be lpossible to ver
(ine it by increasing the spring ten
sin; usually it indicates that the fac
iugs are worn and should be replaced.
At the service stations usually plates
with facing attached may be pro
ured. the old plates being turned in,
bviating the particular job of rivet
lg on the facings. You cannot do a
atisfactory job of cutting your own
acings. The material comes only in
clutch sizes and shapes, and even if
your clutch is old and (ouit of make
the facing manufacturer can supply
you with the right size.
If this type of clutch grips and
there is not a lot of sticky oil on the
plates a trace of oil applied to the
facing will ease it--be careful, for
Ioo much will make it slip. Use
drops, not a squirt from the can.
