If It Does Not Do Bo Freely, You Are Wasting Gas And Wearing Out Something 18 THERE ANY SOURCE OF POWER WASTING friction about your car, which causes fuel waste and wear of moving parts? Some- time, when it is standing on a smooth garage Boor, in neutral, with the brake off, see how much force it requires to push it back and ara and If it seems to move unreasonably hard, look for the causes, or instead, when driving on a hard, level road at 26 miles an hour, throw it into neutral and see if it coasts freely and as far as you think it ought. Manufacturers think so much of such tests that ~ Some of them publish figures of normal force required {0 move and toasting distances of their cars. Among causes of removable friction are the following: Dragging brake-bands too soft tires, too tightly meshed final-drive gears, front wheel or rear-axle bearings too closely adjusted, lack of lubricant in transmission or rear end, or too viscous R0d stringy lubricant used in these housings, non-parallelism of front wheels and misalignment of the front with the rear axle, In the ease of Ford cars too-tight adjustment of low-speed and reverse transmission bands is a very common cause of constant friction. Any- One who once "gets a line" on how his car pushes about or how well it coasts when everything is right, can easily determine whether anything 'is binding: after brake or other adjustments have been made, by repeating these simple tests.

Ryan has demonstrat- | {ed his headlight at Schenectady and | ing the life of a car was along some- is satisfied with it to the extent of | going into production' for its general | use, luminates the road for more than tance could be easily seen. In addi- tion the light shows up the sides of signs could easily be read even when the front of the machine is several feet past the sign! This backward light is one of the | features of the, new headlight. No Fear of Ditches. The jwide side beam is particular- | ly effeftive in rounding curves, light- ing up the road and keeping the ditch in constant view. The beam {is raised one degree above horizontal. Yet, says Ryan, there is no * glare. In fact, tests| showed that the nearer one gets to | the headlights the dimmer the lights appear. At the same time the tests show that persons standing three feet back of the lights and about five feet to either side could be easily seen by persons 100 feet ahead standing in the full beams of the headlights! The Ryan light illuminates the front of the car so that even if bne light is lit the car can't be mistaken for a motorcycle. Thus only a one-fllament 21 | sandlepower bulb is necessary. But provision is made for a dimmer bulb to comply with light dimming laws of various states. Easy to Adjust. The apparatus itself is much thin- ner than the present light but cen- ters its action in a larger lens be- sides a specially designed reflector. A-set screw adjusts the light to its proper height and. a safety catch makes it easy to open the lamp. Ryan is one of the most famous {lluminating engineers of America. He's known especially for his spec- tacular lighting displays, such as those of the Panama-Pacific exposi- tion, the Rio de Janeiro exposition, the Hudson-Fulton celebration in New York, Niagara Falls and others. "Two important ieatures of this new light," Ryan explains, "is the nop-focusing element ands the beam adjustment element. "But the first lamps can be chang- ed without focusing and, in states that permit either 21 or 32 candle- power lamps, thé fixed adjustment is all that is required. "The second feature is valuable In that after the lamps are installed in the car it is only necessary to have someone take about 100 paces in advance while the depressing screw is given a few turns until the observer states that the lamps do not glare. This point is so clearly defined that there is no chance for misjudgment. "An extra turn of the screw will compensate for unequal loading of the car without materially reducing the range." WET RUBBER SHOWS WHY AUTOS SKID Recent tests made by scientists have proved that the co-efficient of friction o water lubricated rub- ber surfac Jaro than on an oiled metal surfdce. By this we learn that wet rubber is much more slip- pery than oily metal---a fact which not only overthrows common belief, but which will be immediately evi- dent if we remember that rubber heels slip more easily on a rain- swept cement sidewalk than leather heels, To the average man such scienti- fic research may seem needless and of little. value, but as a matter of fact it is of great value not only in correcting erroneous ideas but in augmenting the safety of every mo- torist and opening up whole fields of activity never before appreciated. For instance, the results of these tests have caused manufacturers to use rubber as bearing liner instead of the usual babbitt. Even now, on certain types of machines, rubber bearings lubricated with water are being used with greater success and economy than the old type of oll- lubricated white metal bearings. Another thing that these 'tests have proved is that there is. in real- BY ISRAEL KLEIN | { | of Michigan, has more exact figures The new headlight, Ryan says, il-| o 5y4omobiles than have ever be- | fore been compiled. 200 feét ahead, so that a person, | ° e P automobile or any object in that dis-| the road so effectively that road | | He has taken automobiles in Michi- |gan on which to base his figures, | and next. | years.

Heretofore the method of estimat- | what of a hit-and-miss method. Now Prof. C. BE. Grifin, of the University Griffin has applied actuarial meth- ods to automotive statistics. He has given the automobile 'population a "specific death rate" and an "'ex- pectation of life," corresponding practically to those of our own lives. over a number of years, and from these has estimated the number of cars that will "die" during this year Although he expects a loud up- roar from proud car owners, he makes the startling announcement that the lowly Ford has quite a longer life than this average of 7.04 in figuring the average because of against others. Figuring Fords in one class, and all the rest in the others, he came to almost similar "death curves." From his statistics Griffin finds: That the expectation of life of cars in use today fs 7.04 years. That the average age of cars In use December 31st, 1924, was 3.07 years. That the death rate of cars this cent. of the 1926 additions for the entire country, | "That the death rate of cars in 1927 will be 1,810,000 plus 0.22 per cent. of the 1927 net additions and 2.05 per cent of the 1926 net addi- tions.
