EVENING LEDGEB-PHIIiADELPHIA". WEDNESDAY, JANUARY 12. 1918. za ,1 WOMEN AUTOISTS 'FIND REAL FRIEND IN SELF-STARTER compression flgoro Just as high as they dare, with tho result that when the car bon forms, the size of the compression chamber Is reduced and the pressure is rahed to such a. degree that It will cause pre-lgnltlon and Its resultant knock. When n, manufacturer telli ou that his engine Is proof against carbon nnd tho knock ing occasioned thereby, ho Is probably trying to offset more serious "knocks" the car Is receiving from disgruntled users. A friend bf mine has a four-cylinder engine In one of the later models of a well-known car df high speed and power. On several occasions wo havo been out dlv ,Un .nml neftr the city .and after about 125 miles wo seemed to atwasa have trouble with knocking In climbing hllK On one trip my friend had tho carbon burned out carefully before starting. About the time we reached the end of the journey the engine began to knock on the hills from the collection of carbon. On our return to the city he had tho car bon burned out again, nnd the knock ceased. I advised him to raise the cjllndars one fourth of nn Inch by a fibre gasket tinder each cj Under canting, thus Increasing the capacity of the cylinders nnd nnturnlly lessening the compression.. He also had to adjust the water connection and raise the valvo push rods, and a few things of that sort When I last saw him he had run tho car 2000 miles since making the change, and It was just beginning to show signs of knocking under severe conditions, Indicating that the cylinders needed to havo carbon removed. Where the knock Is caused In thla way by a slight compression increase It Indi cates that the manufacturer had put tho pressure as high as the engine would stand, and the only way to cure It Is by raising the cylinders or lowering the pis tons by having shorter rods east. The gasket I have described Is the simplest method. The chauffeur and the auto owner who learn this remedy for knocking-, due to carbon and high compression, wlll.t saved a tot of worry and be enable ( cure the engine's) Ills, or havo It done at tho shop. But, son, take It from mev that carbon naiumulatlon will e-tuse any of the high-powered engines to knock and the only way to cure It li to lessen the compression. Also the only simple way to tower the compression Is to raite ith cylinder with a fibre gasket Both as Sporting Aid and Utility It Is Genuine Boon 'PREFER TO DRIVE CARS Iff NoW for Electrical Gear' Shift, Then livery tning win Be Complete fVnnnr oifiwHw a --SSiviSSr- A fPKa vti.. l, i . . vx-j i u i.

With the crank a thins of memory ex cept In emergencies nnd the start of the motor dependent on nothing more difficult thsn a Btar..p of the foot or the turn of n twitch the whole) situation changed. A woman drlvlrfg a motor down Chest nut street Is no longer a spectnelo that causes wonder among the pedestrians. Po cemmonplaco Is tho sight that cvon tho traffic policemen no longer make excep tions for Infractions of traffic regulations ' en the part of womon. IT IS SPOIIT'S BOON. While a great many women drive their S- own automobiles In the city, It Is In tho iuburbs or in touring mat womon uo most of their own "chauffcurlng." Tho sporting Instinct In this country Is dis tinctly not confined to men. American women are keenly Interested In sports as are thoso of no o'ther coun try. And In spite of tho growing uni versality of the automobile, as a conve nience, there are many phases of Its ac tivities that are essentially sporting propositions. Further, for an American woman at the wheel of her own car, con fidant In her skill to handle It under any circumstances, there Is a spirit of Inde pendence that has nn especial appeal for her. Many women who could afford any number of chauffeurs prefer to drive thejr cars themselves on this nccount. Away they go In the morning to lunch with a friend, with none of tho worry on their minds as to where James Is to get his lunch or how ho Is to earn hi wages while she lingers over tho teacups. ALSO A CONVENIENCE. But to the woman of only moderate Beans tho possibility of driving her own ear with a minimum of Inconvenience has proved a boon. I'orhaps her husband takes caro of the car himself, and they have no chauffeur. Heretofore In tho larger number of Instances, vvhllo tho man of tho family was at his offlco a per fectly good car was lying Idle in tho gar age all day awaiting his return before it could servo those who had Invested In it, what might have been for them, a considerable sum of money. Tho new conditions have altered nil this, and the icu-startcr am most or it. Dut there hnvo been many contribut ing causes. Detachable rims have had a bearing. One man or woman tops have contributed their share. And then, of course, with motor construction on a high plane, engine trouble, the bugbear of til women drivers, Is relegated to tho realm of remote possibility. When somebody davlsci nn electrical ear shift that Is gcncrnlly accepted and adopted the happiness of the woman who drives her own car will bo complete. BIG BANKERS BACK THE CHEVROLET FIRM Contribute Large Sum for the Expansipn of the Great Plant Bankers and great capitalists are cold blooded business men, who leavo sentl went out of their dealings entirely, when they Invest money In any project or "back It," na tho saving goes, they Insist on proof being given that the business has merit and that tho article to be manufactured Is ono that Is sure to meet with public favor. And tho more they Invest the more they must ye made to feel that tho business Is ono free from hazardous risks. Therefore, bankers and financiers, in this respect, are the original "men from Missouri" wno must be ahown. Therefore, when oh of the greatest financial Institutions In America backs a manufacturer for a tremendous amount the moneyed men who take such a risk must have carefully and thoroughly investigated the merits of the article to marketed and been satlsfKW that it S. ab0V8 " ordinary.

And each year, ift spite of this warning, many have had to content themselves with some other car because they could not . get a Cadillac. In spite of steady increases in production, the annual Cadillac shortage is almost a mathematical certainty. There is every indication that the current season will see that condition materially emphasized. There is the steady, stable, year-in-and-year-out CadJJlac demand to be gin with a very large number who automatically repeat. And then, there is the large and steadily growing larger clement of increase in new Cadillac ownership. This has been strikingly marked ever since the advent of the Cadillac "Eight." Thus far its sales have reached the impressive total of more than twenty one thousand cars, amounting in value to more than forty-seven mil lions of dollars. The vogue of the Cadillac Eight has never been perceptibly checked or challenged by any other car. True, there may have been, from time to time, cars which in advance gave promise of comparable charm. But their appearance served rather to stimulate admiration for the Cadillac and to emphasize its inimitable qualities. Cadillac prestige is based on the universal esteem for the soundness of Cadillac policies and the soundness of Cadillac principles of construc tion and the feeling that the new Cadillac exemplifies the most luxurious form of motoring yet evolved. Cadillac prestige is steadily growing greater the Cadillac demand will go right on expanding in volume and in enthusiasm. Therefore, when we urge you to assure yourself of Cadillac delivery, it is that you may guard against disappointment. Tf you can secure a Cadillac now, protect yourself, and take it. ,' If you cannot do better than to arrange for delivery in a month or two, we urge you to take that precaution. rffi."1 -TJ7Ttf A3j"Wj XWJbbbbbI 7tJuH :i? i - iV .iVtl'jr.BK 2trarenj.&w BBt i 'mj WSS&S f -I'YT. ?'. n s i i T 3 1 i" t i A s,i '1 ! t t ir i i i t F4 L w v?rwM sip
