John Smith and His Car BY FREDERICK C. RUSSELL. THE SUN’DAY. STAR, WASHINGTON, D. ¢, JULY 19, 1925—PART 3. John Smith is a character whom every motorist should welcome. He it mot selfish; rather he is a motoring martyr, a chap willing and glad to have exploited, in an interesting way, his experiences for the benefit of the other 10,000,000 or more members of the motor clan. No. 107—Pranks of the Pistons. ‘Whenever Smith is discovered in | omparature change: ap the act of listening to the way other | - motors run it is a foregone conclu alloy that did not receive sufficient heat treatment. It is too sensitive to cause whenever you climb hills it knocks badly, even though you have the carbon removed regularly. The trouble is that in trying to thin out the cast-ron pistons in your engine the factory went too far and sacrificed heat conductivity. When the engine gets hot and the gases that are up in the thousands of degrees are heating the tops of the pistons, the metal starts to glow, immediately forming hard particles of carbon, which also glow to Incandescence. Then the pre- ignition of the gases starts and you have a varlety of knocks.” Smith decided the lesson to learn from all this is not to knock any par- ticular kind of metal or design of part until all the facts are known, BEST TIRES IN FRONT. Always run the strongest tires on the front wheels as an extra precau- tion against front-wheel blowouts. Since low-pressure tires have come into style, however, there is another reason for putting your best tires for- ward. It is the matter of front-wheel wabble. Wabble, regardless of its causes and cures, cannot start until the stored up forces of vibration have exceeded the friction resistance to such forces as offered by the action of the tires against the road surface. The rougher the tire treads, therefore, the greater the friction, and the faster the car will have to go before wabble R oy (¢ o 3.

This model was an instantaneous success. Buyers acclaimed it enthusiastically. Other makers immediately began to copy or imitate the Rickenbacker. Demand has been overwhelming — far beyond factory capacity. All Rickenbacker plants have been running extra forces and over-time, trying to catch up with orders.
