NEW RECIPROGITY PHASES STUDIED District and Maryland Of- ficials Confer on Further Auto Agreements. Bpecial Dispatch to The Star. BALTIMORE, June 12.——A series of conferences between State and Dis trict of Columbia authorities relative to points not covered in the reciprocity agreement have been held the past week. As a result of the conference, Motor Vehicle Commissioner ~ E. Austin Baughman has notified Director of Traffic M. O. Eldridge of the District of Columbia that reciprocity does not extend to vehicles carrying loads in excess of the maximum allowed in Maryland, or in cases where other special provisions are violated. Efforts were made recently to com plete an agreement between the State and District governments re- zarding vehicle load weights, width of tives and licensing of vehicles actively in use in both jurisdictions. Officials of the department of the attorney general and the motor vehicle com mission were unable to secure comple- *tlon of the agreement by Washington officials, it is said, although Mr. and Deputy Commissioner Plans to complete agreement of reciprocity grew out of problems of licensing interstate motor was said. It was agreed such busses and motor trucks be | sed by each jurisdiction in which Use of District licensed trucksin | Maryland for periodic operations re. quiring temporary quartering of the vehicles in this State also was held to require issuance of Maryland license tags, Mr. Schroeder said, in spite of reciprocity for vehicles oper- ated for pleasure purposes and ordinary commercial use. Similar limitations upon reciprocity privileges were made necessary due to variations in the State and District regulations concerning maximum load weights. The District law permits_a maximum weight of 24,000 pounds, two tons in excess of the Maryland maximum of 20,000 pounds. Regulations concerning permitted weight per inch of tire width alsc differ, according to Mr. Schroeder although the District regulations ap. proximate the Maryland requirements that such loads must not exceed 650 pounds per inch in width of tires.

In an old edition of a book on car care the list of supplies which should be carried in a car that goes a-t not counting the quantities of those articles touring includes 38 different articles, These do not include the con- ventional tool kit articles, such as wrenches, screw drivers, jacks and tirs- changing equipment. Tt is somewhat startling to record that the average motorist nowadays carries just four of the articles listed, namely spark plugs, oil can and a search or even carry these. “spare headlight bulbs, spare trouble light. Many of them do not Among the articles that are no longer dcemed necessary as emergency equipment are spark plug terminals, calcium carbide, coil unit, gaskets, cot- ter pins, candle wicking, valves funnel and measure, collap. valve springs, valve-grinding compound. le water pail, gasoline emergency tank and electric cable. Apparently times have changed. A few of the “old-fashioned” things in the repair kit of yesteryear could be carried in new cars today to great advantage. Just one of these articles, the spare fan belt, suill should have a prominent place. Wire, tire tape and a small box of assorted bolts, nuts and pins may come in handy. The wise motorist still carries such things. The United States is a big place. What's In an Auto Name. Among popular pastimes with a motoring flavor why not try offering suggestions for names for future cars. ming cars after historical person- ages, planets, Presidents and promi- nent people always h: been popular, but the possibilities are somewhat ex- hausted, unless one lapses into the ridiculous. Automobiles have pros- pered on distinctive names and such nomenclature bids fair to be popular in the future. Among the odd names suggested for future use may be mentioned: Auto Dynamic, Automotor, Aerocar, Angus. Alpena, Adria. Bolte, Bram- well, Berg, Blood, Black Diamond, Blomstrom, Bugmobile, Browniekar, Ben Hur, Beggs, Chapman, Canda, Cotta, Conrad, Centaur, Crestmobile, Cameron, Correja, Church-Fleld, Climber, Darling, Dyke, Du Dis- patch, Everybodys, Economy, Eclipse, Fanning, E. R. P.. Friend, Gasmoblle, Gearless, Hay Berg, Heine-Velox, Kid- der, Kunz. Don't get excited! These are names of a few of the cars that are dead nd gone. One can hardly think of a ild name that has not been used for some make of automobile Yes, even “Rapid” and have been used. One “Merit.” Pedestrians a Problem. Street and highway safety officials, while they have had their full meas- ure of troubles with the motorist and in getting necessary laws and regula- tions, are perhaps even more con- cerned over the pedestrian situation. These officials show that it is possi- ble to control motor traffic. It is possible to get adequate laws and to secure their enforcement. But in the matter of pedestrians the question is omplicated. Laws governing pedes “Success’ was . called. trian_movement in congested sections are few and far hetween, and their enforcement is a question of the greatest difficulty. On every hand, in every community, pedestrians are fu-nishing safety and police officials with the hardest kind of a problem. Whereas the motor ve- hicular traffic question is one which, while it is by no means settled, it at least on the road to a reasonable degree of stability, that of pedestrian control remains a theoretical one in many communities. The point is made by safety leaders that it s to this fact that much of the traffic accident problem can be traced. Lesson in Lubr Heavy oil is being service statlons for cha lubrica- tion on new cars. Tight shackles are better off with oil, but cars more than a year old should have grease. Starting with oil, however, prevents clogging troubles which so frequently occur when grease is the steady diet. More pressure can be exerted with the hand grease gun of the hooster type than with the large equipment used in many garages and filling sta tions. The hand operation seems to be more tedious but it does the work. When oil mileage seems to be on the increase it is only a warning of crankcase dilution. Ofl mileage should become less as the car grows older. rtion. used by many Now You Have It! Answers to last week's questions. 1.

Accurate appraisal of the power output of automobile and truck en- gines under varying conditions of temperature, fuel mixture, spark and throttle setting, carburetor adjust- ment and the like always has been a difficult problem for the automotive engineer. The number of cylinders to be tested, thelr variability and the high speed of the engine have been the factors that have contributed most to_the problem. Such studies usually are made with the aid of instruments that produce indicator diagrams, some of which are. made by a beam of light that traces lines on a photographic plate, while others are traced by a pencil on ruled paper cards wrapped around a re- volving drum. With the former type of instrument it is necessary to de velop and print_the negative, which causes delay and some liability of dis- torting the diagram, while with the latter type the weight of the pencil and drum causes a lag in their mover ments that makes them unreliable for indicating engines at speed of more than 300 revolutions per minute. New Instrument Developed. A new indicating instrument that does not have any of these objection- able features has been developed by H. M. Jacklin, assistant professor of e engineering at Ohio State ty, and C. P. Roberts, and ribed and demonstrated by acklin at the Summer meeting the Society of Automotive Iingi- neers last week This device is attached directly to the head of the engine to be tested and is operated by the engine.

Used in Routine Tests. The new indicator enables rapid and accurate work to be done when in- vestigating multicylinder high-speed engines, and varlations in valve tim. ing, valve lift, ignition timing, and other things that affect the power of individual cylinders hecome apparent immediately and can be corrected. It can be used in routine test work in engine or car manufacturing plants and, If small inexpensive provisions are made on engines in production, it can be used in service stations, ac- cording to Mr. Jacklin, to check valve and piston ring fits, ignition settings, carburetor adjustments, and other things that are now done, at best, only by guess. BETTER TAPPET WORK IS STRONGLY ADVISED Important to Ses That Clearance Will Remain Constant—Two Ways for Doing It. Before concluding that the clearance between valve tappet and end of valve stem is correct it is important to see that the clearance will remain con- stant. This is done in two ways, de- pending’ upon the type of tappet with which the car is equipped. A mushroom tappet has a flat, round bottom that rides its cam or lifter on the camshaft. It can be turned around, this being provided 80 that the bottom will not keep strik- ing on one spot all the time. But in use the bottom tends to develop high and low spots. In turning a tappet one often finds the clearance changing. A roller tappet is just what its name implies. In order to allow the roller to turn to a new position, the engine should be cranked over and another test of clearance taken when the valve is closed again. A contract for the construction of a 130-mile automobile road in Mexico from Perote, the terminus of the road from Mexico City, to Vera Cruz v Jalape has been let to an American firm. The completion of this road will make a highway from Mexico City to Vera Cruz of 3 miles. In the unflagging brilliance of Oldsmobile perform- ance; in the luxury of its riding qualities; in its ef- fortless control and un- canny inclination to hold to the road —Oldsmobile owners find endless cause for glowing praise. This praise, so widely voiced that all may hear, ever- increasing thousands wisely heed. OLDS MOTOR WORKS COUPE 925 7.0.8. LANSING WASHINGTON BRANCH 1625 L St. N.W. David S.
