- SEEKING TO SOLVE ENGINE PROBLENS Standards Bureau and So- ciety of Engineers Would Promote Car’s Usefulness. A concerted attack on the problem of internal wear in automobiles and truck engines, with the object of increasing the period *of usefulness of motor vehicles to_their owners, is Leing made by the Bureau of Stand. ards and the research committee of the Society of Automotive Engineers in co-operation with a group of auto- mobile manufacturers. Varfous lubrication problems that are common to all machines are con- idered of enough importance to war- rant a careful analytical study. Among the companies taking part in this movement are the Autocar, Chevrol Chrysler, Dodge, Mack, Maxwell, Packard and Rickenbacker. Samples of Oil Inspected. The companies, in furtherance of this study, are sending to the Bureau ds samples of used lubri- oil taken from the crankcases s and trucks operating _in lar service in different cities. The 1ples are being taken from 10 cars n W J~h&|\;:luvl, Detroit, Birming- Minneapblis, New Orleans, Tulsa an Francisco. These cities were representing the desired in climatic conditions and such as the dust car- fed in the alr that the engines must breathe. The 170 samples so. colle yzed at ex of the wear of cylind on rings and crank selected ation ed will be and co necting-rod bearings that results from | the presence of various materials that contaminate the oil in the engine, such as dust, water and the heavy ends of hydrocarbon fue Results of Analyses Noted. Results of the analyses will be fur- nished to the co-operating manufac- turers, and a summary of the investi- gation will be compiled later for the information of all concerned. Positive knowledge of the materials that im- pair the lubricating quality of olls and cause most wear will enable the manufacturers of cars and trucks to | devise means for increasing the life of motor vehicles. This new undertaking is a_con- tinuance of the study of the lubrica- tion_problem which the Soclety of Automotive Engineers has been carrying on for several years in con- unction with the Bureau of Stand ards, the National Automobile Cham- er of Commerce and the American Petroleum Institute. Problem Is Complicated. The problem has been complicated by the use of certain types of fuels, including those of low volatility that do not burn completely in the cylinders, as the unburned fuel makes s way into the crankcase and dilutes the lubricating oil. This lowers the viscosity of the oil, making it less effective as a lubricant. Water and dirt also decrease the lubricating value of crankcase oils. 1t is for the purpose of advancing more rapidly the efforts of auto- mobile mhnufacturers to improve their products that the present re- search work nas been undertaken. MACCABEES TO COME HERE BY AUTOMOBILE | Caravan to Bring About 10,000 to Quadrennial Convention £ in July. Approximately 10,000 delegates and visitors to the quadrennial convention of the Maccabees, to be held here in ly, will motor to Washington from all parts of the United States and Canada. In the last year automobile caravan trips have been organized in Maccabee lodges. Delegations from the Pacific coast will start about the middle of Ji and all along the routes the init arties will be joined by other cars until thousands of cars will be in line in the main caravans by the time Washington is reached. A complete route system has been laid out, leading to Washington from different sections of the country, with hundreds of feeders connecti virtually every city and town of any with the n caravan routes. d Maccabees will follow way, starting it The Yellowstone Trail Ory nd .

The 1925 crop of tourists, it ig esti- mated, will be worth two and a half billions of dollars to the many com- munities located along the play- grounds of the Nation and along the highways and trails leading to the centers of motor tourist traffic. These figures are based'on data supplied by pivotal sections of the country where the business of catering to motor tourist traffic has been placed on a dependable basi Florida’s harvest of tourist gold is estimated at $500,000,000, California is making preparations for a million motorists this season, with also half 4 billion dollars as its goal; the North- west, with Colorado as the gateway of the region, will run a close second to California and Florida; 125,000 cars registered in Colorado last year, ac- cording to the Denver Tourist Bureau and at the rate of yearly increases the mark for this season is 175,000 to 0,000 automobiles. According to offi- clal figures 75,671 motorists entered the State of Oregon last season. As compared with 815,916 cars which registered in the national parks last vear, the park service is now 1ook- ing forward to a banner year with 400,000 cars as the object 25 Per Cent Gain Expected. With conditions for touring more favorable than ever before there is every reason to expect at least a 25 per cent increase in the numbr of au- tobiles that will make long-distance the national touring board of » A.

Henry, president of the American Automobile Associa- tion, declared. Mr. Henry attributes the tremen- dous growth of motor touring to four principal factors, namely, the exten- sion of the good roads program, the increase in the number and efficiency of motor clubs, the realization on the part of the average motorist that only Dby greater use of his car for pleasure does he .get the most out of his in- vestment and finally the development of community organization to attract tourist traffic. He sald: Ownership Worth While. ““There was never a better time to own an automobile. In the past twelve months a total of $1,000,000,000 has been spent on road building and main- tenance by the Federal Government, the States and the municipalitie Many.of the transcontinental high- ways have been improved, $60,000,000 baving been spent on the Lincoln highway - alone, while 40,000 new miles of rcad have been constructed. “Motor club service has been enor- mously extended.

There few places in the land where e A service will not extend. Our is to follow the tourist through. Our national touring bureau issues to each club a road report on condi- tions of the main or arterial high- ways of the country. This is an im- portant service feature and should help to prevent the congestion of traf- fic on the main trunk lines. “There are more than 3,000 motor camps maintained by communities and by private individuals.

If attractive and well kept these hotels can do business with the motor tourist who neither cares to camp out nor to invest in the luxuries of the big city hotels. The large amount of money that changes hands as a result of tourist travel goes to show once more that good roads are of far greater value to the community than they are to the individual motorist. Every community located on a road used by tourists re- ceives its share of this money and those communities which realize the value of this business and put them- selves In a position to profit by it will be the ones that will receive the major part of this great source of income. In addition to the money given by the motorist to the hotels, the garages and the service stations on his way, the motor tourist is in many cases a prospective investor. Many of them are seeking new homes while thou- sands settle in communities they visit. | Many purchase unimproved land. For this reason the motor tourigt occuples the position of an important agency in the creation of community values. If this factor was more clearly recog- nized motordom would not have to fight so many legislative proposals of an annoying and restrictive char- acter. “While the material results of mo- tor touring are tremendous, perhaps the greatest benefit accruing to the country from the development is the social influence. Hundreds of thou- sands of families of limited means now enjoy annual vacations,.visiting the beauty spots of America with their cars. Seashore and mountain, national forests and parks, lakes and streams are all avallable to millions of our citizens at a cost very. little higher than our ordinary living ex- penses. To put these within striking distance of the multitudes swarming in our industrialized cities is one of the great boons that the automobile has brought to our modern clviliza- tion.” New York Declares War on Hit-and-Run Automobile Driver New Motor Vehicle Law Drastic on Failure to Report Accidents. New York is out to get the hit-and- run driver. The new motor vehicle law of New York State contalns drastic provi- sions concerning reports of motor ve- hicle accidents which result in a per- sonal injury or death. Failure to make a report of such an accident is made a misdemeanor and is the ground for suspension or revocation of the driver's license. A statistical section of the New York motor gehicle department is be- ing organized and, from the comiplete reports of motor vehicle accidents, & study will be made of causes and of remedial measures. o The New York law requires that, in addition to the vehicular accident re- port by the police and the persons in- volved, a report of deaths to the com- missioner of motor vehicles also is required from the coroner.

WHOLESALE RIMS FOR ALL WHEELS Rundlett Rim Co. 1336 14th St. N.W. suggests the CADILLAC ASTYPE OF FUTURE Best Adapted to Lightweight Rim, Is View of L. J. D. Healy. The tire of the future probably will be developed along the lines of the balloon tire, in the opinion of L. J. D. Healy, writing in the current issue of the Journal of the Soclety of Automo- tive Engineers, on pneumatic tire ele- ments and development. The trend toward lighter and more economical cars evolved the balloon tire, which is lighter, but of sufficient size to give proper cushioning against road shocks. “Tires in the future, according to Mr. Healy, will be flexible, of generous proportions and as light as possible consistent with strength and durabil- ity, and they will be adapted to a lightweight rim. Of necessity, they will follow the trend of motor-car de- sign, which, it is predicted, will be along the lines of reduced unsprung welght. Lighter Unsprung Parts. “The less weight there is below the springs the better it will be for the tires and the occupants of the car,” says Mr. Healy. “Removal of the brakes from the wheels to the sprung part of the chassis, together with the use of lighter axles and wheels, will allow the use of lighter and more flex- ible tires. The automobile, spring and tire engineers, working in unison, will no doubt some day evolve the long- looked-for comfortable, high-speed, economical, lightweight car. “A balloon tire is nothing more nor less than a lightweight cord tire that | has a greater volume of air at lower pressure. It does not require so heavy a carcass to withstand the strain, fewer plies of cord are needed, n more flexible carcass can be applied, and this in turn gives yielding periph- ery of the wheel. In consequence, vibrations and shocks are absorbed to a greater degree than by the stiffer- ‘walled, high-pressure tire. Tests Prove Value, alloon tires on test cars have given consistently good service with very little trouble from punctures and blowouts. The service is almost equiv- alent to that of the regular high-pres- sure tires. Some persons have claim- ed that more punctures have occurr=d with balloon tires, but experience has not shown that to be the case under the road conditions of many States. “On the whole, balloon tires have given practically the same durability as high-pressure tires, except that the tread wear Is greater. But it is be- leved this wear can be overcome by the proper distribution of the rubber in the tread stock, Wearing Power Discussed. | “The wear |s greatest on the outside of the tires on the front wheels and on the inside of the tires on the rear wheels. The former is due to the pitch and toe-in of the wheels and the latter to the slope of the road surface. Al- théugh the wear on the rear tires is greater than on the front ones, the off-center wear is more pronounced on the front wheels.” AR By L S Butternut and walnut trees pro- duce a sweet sap very like that of the sugar maples. { | | DEHCO | Baked Enamel | On Automobiles | MEANS , Sun Protection || | DEHCO PLANT ’ 1724 Kalorama Road Columbia 7163 | WASHINGTON, D. €, APRIL 19, AUTO THEFTS MADE EASY.
