Must Know Meaning. | Now that these old nolses are hav- ing their inning, along with a number of mew ones, it is important for the |driver to know what they mean. Usually they mean very little, but if | he has no way of proving it, his mo- toring is quite as unpleasant a matter as it would be if a bearing burned out every few dayvs. Thus on a cold day the man with a new car may be alarmed to hear a certain clattering in_his engine, but if he analyses the affair carefully he will conclude that he iz hearing a piston sl during starting on a | cola day. nding what the | engine has to say he can save him- sell the trouble and expense of taking 4 new and almost perfect engine to a repair shop. A noise that will trouble many driv- ers within the next few months can be traced to the tendency to use smoother clutches with more powerful engines. The driver himself ulso will play a {Tole in this little drama of motordom. | Without any apparent warning the | driver will hear the car give a ver peculiar deep-toned groan, and unles he is aware that cars are talking a somewhat more elaborate language he will be postponing his trip or his day's outing unnecessarily There is an unwritten rule in motor- dom that the smoother a clutch the likelihood there is for a driver doing.

A fender is excellént for this, as such a part of the car could be removed and done over with very little trouble. If the polish is for the painted body. ra- ther than the enameled parts, fry a strip at the bottom of the doors. Never tackle the rear deck until you are thor. oughly satisfied with the reliability of the poli when his foot is still on the clutch pedal. The clutch will groan angrily as it slips, and the driver will be due for clutch trouble in the near future if he does not succeed in discovering that he is actually causing the outery from the car. Warnings Are Pla The remarkable and fortunate part of it is that the car should glve its driver such plain warnings rather than to tell him what a dunce he is to provoke such conversation A driver will step on the gas too suddenly and back will come the clicking from the cvlinders to tell him that such im patience will not do. He elther must retard the spark or feed gas more sparingly. This is well illustrated in the case of the starter. He steps on the starter button and hears the heavy grind of the starter gears as they mesh with the flywheel ring gear and churn over the engine. If there is just a light hum from the starter when he steps on the button he is politely informed that the gears have not meshed and that he is wasting his time as well as the battery’s energy. Some of the newer noises, however, are not so obviously helpful. A case in point is the cracking nolse pro duced by the expansion of the long exhaust pipes now used on most cars On a very cold day such expansion will puzzle the driver, and If he Is not careful he will be taking his to a repair shop to have them look for a broken spring leaf. It is that kind of noise. The motorist who ix posted on the modern automobile’s enlarged vo- abulary will take the cracking noise s a warning to put more alcohol into | the cooling system and adjust his car. buretor for a little richer mixture. The noise means bitter cold, but sit- ting in his snug sedan with the heater | blowing up warm blasts he may not understand what the car is trying to Hood Noises Annoy. Of late there has been a tendency to hold hoods down with very power- {ful springs. With balloon _tires, | higher speeds and no regard whatso- |ever for a small thing like a rough {road the body of any automobile is subject to a number of twisting forc Unless the hood is held down tightly it will set up some very annoving noises. Every now and again, how- ever, some careless garageman will tail to clamp the hood down properl A little while later one of the clamps will snap into place with a startiing thud. When this happened to one driver he thought he had cracked the frame of the car. It was a rather na- tural conclusion to draw, because the clamp snapped into place just as the car hit a bad hole in the road. Changing conditions in driving play their role in either creating new car noises or in bringing old ones to the fore. Take a windshield that has a habit of rubbing against its rubber strip with a sidewise motion, then add the sort of wind pressure that goes with 40 miles un hour and the wind- shield is golng to have a few things to say. This is particularly true if the rubber strip has become Sty More intensive driving in w -, and widespread disregard for of using lighter lubri budget now cold { IN MAKING OF FORDS | Stones Often Break in Pieces After, § Little Use—Some Last ' Long Time. No diamond owner could he persuad ed to press a large and valuable stone against the whirling surf of u grinding wheel or drill holes in_fit, yet this takes place every day in De- troit plants of the Ford Mator Co., where move than 1,000 caruts of these precious jewels are used in the manu- facture of motor cars. The majority of the stones are used either to dress grinding whrels or are drilled to permit hundreds of miles of wire to be drawn through them daily. Even a diamond will not stand up under long treatment of this sort and steadily loses weight. The big gest stone ever used by the company, weighing approximately rats, lasted about two v . yet othe be- came valueless after a few weeks' use or broke down Within an hour. One dlamond of the commercial variety will bury itself in the toughest steel, although a stone weighing several carats broke fnto innumerable pieces when dropped on concrete floor Diamonds come into use when grind- ing wheels pick up enough steel to hecome glazed and grooved. The jew- els are forced ainst the running wheel until the old surfuce has been cut away Development of of greater hardness has re diamonds of the heaviest ¢ ing work now are used only in the ressing operations. In the drawing of copper wire from the size of a lead pencil to the thickness of a hair, there is no substitute for the diamond, through which holes are drilled by using diamond dust driven through by an oscillating needle PARKING CORRECTLY. Experienced Driver Uses Engine to Save Steering Assembly. Turning the wheels straight ahead or in toward the curb when parking or when starting away from the curb | can always be stmplified by allowing the engine to move the car slightly forward or backward while steering. A lot of unnecessary wear ix inflict- ed on the steering assembly by trying to manipulate th® front wheels while the car is not in motios cants in the transmission help to pro duce odd and unnecessary gear noises. Engineers have found that tl 3 and the amount of iubric zear case plays a role in_determining the tone of the gears, but the ave £ driver still has to discover that his automobile knows all about it and is trying to broad t the news. The more « car talks, however, the quicker the driver what it means. Perhaps its new habit of talking a new dialect will help him become more versatile nd better able to render these intimate conversations a genulne saving on dispositions and pocketbooks.
