AUTO DRI VERS ON TOUR GET ADVICE 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. Little ('nire leiqnired. The wet multiple. disk clutch runs n oil, usually the bath, cofineted with lhe engine. It ,dqes not require much care other than to clean it ot with kerosene when the crank case s cleaned. If it slips there is not ng to do but tightell the spring, or Sto loosen it if it grips and is nt I dirty.
