\ ORANGE AND BLUE HEADLIGHTS PREVENTING GLARE DESCRIBED Society of Automotive E Will Hear of New Rim, Worm Drive for Cars, Racers Prevention of aytomobile headlight Elare by the use of lJamps that throw her orange or blue light at the will of the driver, and the use in combi- nation with these lamps of similarly colored glass screens on the wind shield, will be described at the annual meeting of the Society of Automotive Eingineers at French Lick Springs this week. The subject will be K. D. Chamber; Knowledge Press. The orange scresn filiers out blue light rays so that when - using blue light approaches. its lamps ap- pear as it dimmed almost to extinction while the orange rays projected by the first car pass through the screen nd the oncoming car and the the road are clearly visible.

First it is neces- | sary to find out what makes them un- comfortable, and much study has been glven to this problem of late. It is a difficult one Lecause it is complicated by the many d motions caused by road surfaces, by engine and other vibrations and by the effects these all have on ihe body and mind of the rider. At the rviding qualities session on June 3 R. W. Brown, engineer, will describe new electrical instruments that have been developed for taking easurements of the direction, size, te and duration of the oscillations nd smaller vibrations and tell some ©f the results obtained with them. An idea of the difficulties overcome is given by the fact that-when a solid rubber tired wheel passes over a rec- tangular obstruction 1 inch high at a rate of 9 miles an hour, the greatest upward thrust of the axle lasts only about one-thousandth of a second. The higher the car speed with a pneu- matic tire, the less the axle deflec- tion. while with ushion tire, the amount of deflection increases with | the speed. At the same session the effect on riding qualities due to seat cushions and cushion springs will be explained. Road inequalities and obstructions are the primary causes of most dis- comfort endured in an automobile, and h the automotive engineer to improve the riding qualities is done to compensate for the imper- fections of the road surface. For this reason a descriptive report and a series of motion pictures showing pre- clgely how a truck and its tires react to road obstacles, which will be pre. sented by J. A. Buchanan of the Bureau of Public Roads and J. W. Reid of the Rubber Association of America, should assist the engineers %0 a solution of the problem of springs and tires, i Worm Drive for Cars. { Many passenger cars of the betrer | class may soon be driven | \\.\I‘lll-K gearing, as many motor trucks and motor coaches have bheen during \hl‘; last 10 or vears. This will come about as the result of the higher speed of the vehicles and the demand for low-hung cars and silent operation. Successful use of the worm-drive axle in motor coaches proves that this type . of flnal drive is as strong as any to transmit the high power of the engine at high speed, and that it has very Jong life. One set of worm and worm goar that has given 300,000 miles of service in a motor coach shows very little wear and Is evidently good for many more miles. A new type of worm-drive axle with an_undersiung worm is to be il- lustrated and The fact that the worm i instead of above e makes it possible 1o lower the propeller shaft and consequently all the rest of the vehicle. The frame, engine and body tan be nearer the ground without re- ducing the road clearance below that of the bevel gear drive axle, and the fear seat can be brought nearer the floor level thus affording more head- foom under a low vehicle tor. Another new type of final drive ear, called the hypold. is to be de- ribed by A. L. Stewart and Ernest Wildhaber. In informal b and other m 8.

One of |the reasons is the use of super- | chargers, which are likely to become | | common on the better class of private passenger cars within the next few | vears. Another is that the engines are of the straight eight-cylinder, | high-speed, long piston strolke type. | What the other featares are remains | | to be disclosed. | "Inline with this subject is the prob lem of studying the power output {of multi-cylinder, high-speed engines, | eat difficulties.
