AUTO IMPROVEMENTS MAKE ROADS SAFER Better Methods of Control S'm- plify Problem of Regulating Traffic. NOW QUESTION OF SALES More New Cars Sold Mean Less Accidents. Something distinctly new v of traffic regulation and s: work is offered in a bulletin just i sued by the Washington Automotive Trade Assoclation to the effect that traffic and safety can be narrowed down to a sales problem. The thing that is doing more simplity traffic and safeguard ts and pedestrians s the auton it is declared.

But his plan would have gone| the way of all resolutions had he not been caught on the road with 2 “dead” engine. He was literally forced to learn or be stranded. It happened that I was in the car with him, but when he looked at m as much as to say, “Here's.a job for you,” 1 decided -to,let him worry over matters a while and learn by the “deduction” method. “I'm su-e the trouble is in the wir- ing” he bezan, “because the engint | stopped suddenly. without any hesi- which s usually the case when line is to blame. 1 wonder If |¢p, iences for benefit of the other 10,000,000 or more members of the motor clan. | through the shaft is distributed to After the trouble he had had With| rotor which works in unison with the the contact points by means of a timer, so that the spark arrives at | each cylinder at the right time.” t this point Smith lovked worried cre’s o thing that puzzles me.” ho aid. “For electric current you have 8ot to have two wires—one for the positive charge, the other for the negative. How does the spark get to the plug through these single wires?” How Systemn Operntes. “Did you cver see tw6 overhead wires to operate a street car?" asked by way of arriving at an ex- slanation. “The positive current gocs through the overhead wire and the car completes the electric cycle throush its contact with the tracks and the ground. It's somewhat the same with the ignition system of the utomobil >, 1 grounded to the metal frame. There- for you need only a one-wire system, ugh some cirs arc equipped with ~wire system for lighting." The negative wire is | “By induction,” I explained. “That's why the arrangement is called the ‘induction coil’” This is the thing practical jokers use when they give you an electric shock. When the cur- rent is interrupted in the primary coil, electromotive force of high volt- age is Induced -in the secondary. If the ends of the wires of the secondary winding are slightly. separated, a spark will jump across the gap. That 18 what happens at the spark plugs. The current in the primary is inter- rupted by the ‘make and break,’ which is timed to work in harmony with the rotor. There &ro many details to the subject, of course, but this is the prin- cipie of the ignifion system.” And to make it clear, we decided {to follow the current from the bat- tery to the plugs. The lesson proved to be of twofold value, because Wwe disco.ered that the wire to the posi- tive post of the battery had not been properly connected. The current was mot even reaching the ignition sys- tem, so it was not difficult to under- stand why the engine stalled. ' Had an experienced motorist been looking for the trouble he would have dis- covered that the battery was in some way to blame when he tried the lights and found they would not burn. But Smith lost nothing by taking the de- tour, y Next Week: (Copyright, Blowout." ¥ the Ullman Festure ) IBER—WE SELI (B:3882 | HOOD—SILVERTOWN and APRIL_ 21, PREPARE SCHEDULE FOR AIR PRESSURE Makers of Balloon Tires Compute Figures for Sizes of Automobiles. Lower alr pressure in balloon tires has made it necessary that proper in- flation schedules be graduated at fre- quent intervals. A 6.20 balloon tire, for instance, under load of 1,060 pounds, should be inflated to twenty- six pounds air pressure. Assuming that another passenger got into the car, adding eighty pounds to the load for that tire, the air pressure should be increased to twenty-eight pounds. In studying this condition for all types and sizes of balloons, Miller tire experts foresaw the confusiol which might result In the motori: 1924—PART 3. mind when driven tp change his In- flation pressure with the addition of each passenger, and worked out & schedule which overcomes the difi- culty without reducing the comfort of the ballooning or threatening the life of the tire. It is recommended that the inflation for roadsters and coupes be kept at the point required for two passen- gers; for five-passenger tourings and sedans, at the point required for three passengers, .and for seven- passenger tourings and sedans, at the point required for four passengers. When this procedure is followed it {5 not necessary to change the in- | flation pressure for additional pas- sengers. 1f the tire is ‘kept inflated to the minimum pressure recom- mended for the car with one passen- ger, and five Or seven passengers are carried, there is danger that the tire will go out of service prematurely. —— RIMS AND TIRES. - If the car owner, after being out in bad weather, will take the trouble to wipe the tires and rims clean with a sponge and then wipe them dry, es- pecially along the beads, he will do much to prevent the formation of Type LA lgn\ition for Ford Cars Driving in Traffic Made Safer rric driving is made easy whenyour Ford is equipped with ATwaTer Kent Ignition.
