Consulting Engineer, Mot-eland Motor '. . ! Truck Company , PART 2 jpncumatic Tires The great . advantage of the , pneumatic tire is that it can ab sorbt obstructions on the road without ! raising the axle. For this reason, it will eliminate the many small vibrations and jars arising from the many small ob structions or road inequalities. A tire containing air under pressure is very quick in yielding and in returning to its, original position (as .compared with a solid tire) hence does not consume as much power as a solid tire and will have more speed. , Other: advantages of the pneu matic tire are greater deformabil ity, that is. it will deform or adapt Itself to the road surface more readily than any other tire, and in consequence it is easier riding. It has a higher elastic ef ficiency,! or in other words, it con sumes less power than the solid rubber tire. The disadvantages of the pneumatic tire are its well known susceptibility to punctures, blowouts and valve leaks. The air in the Inner tube is re tained by the fabril casing; of the tire; this casing must be strong enough, it must be composed of a sufficient number of plies of duck or fabric to withstand the air pressure inside the tire. The thicker! the casing or carcass of the tire; that is to say, the greater the number of plies or fabric of which it is composed, the lower will be Its efficiency, for more energy is required to deform it or flatten it as it rolls on the road and is accommodating itself to the road surface. ! To demonstrate the amount of power which is was ted even with pneumatic tires, try to indent or flatten a casing by hand before any I air is : pumped into the tire. When a car is in motion four tires have to be de formed continuously and this con sumes power. : Cortl Tires The more flexible the wall of a tire Is, the less Is the power wast ed and the greater is the tire efficiency.- In a cord tire the car cass is made of a number of strands of cords j tied together, (and not of cotton duck, as in fabric tires) and this can be de formed much ! more easily than a fabric tire. For ithis reason a cord tire is "faster" than an or dinary fabric tire. Being softer and more "deformable" a cord tire will also absorb larger ob structions on the road, as for in stance when passing over stones. Its absorption quality is better, there will not be so much, pressure between the small stones on the road and the tire, since the tire will largely rest on the road sur face while at the same time, per mitting the small stone to imbed itself into the tire. For instance, say a small sharp stone projects one-half inch above the road sur face, the cord tire will absorb the stone so to say and yet the max imum load will rest on the road surface in front and behind the stone. A fabric tire would not be able to absorb so high a stone and hence the entire load support ed by the tire will be resting on the small stone. ' If this should be sharp, a puncture is liable to occur. This is the reason why less trouble Is experienced through punctures with cord tires than with ordinary fabric tires.

This won derful motor train will consist of four luxurious Pierce-Arrow twenty-passenger : parlor ; cars, equipped with deeply upholstered individual chairs. The equipment and service to be embraced on this tour mark the establishment of a new high standard in American travel, offering remarkable com fort and easy riding qualities, with splendid view of the country through which the motor train will pass. i : The route to be followed by the "Covered Wagon of 1924" is as follows: New York,' Philadelphia, Gettysburg, Pittsburgh, Cleveland, Chicago, Omaha, Newton, Kansas, Garden City, La Junta, Colorado Springs, Trinidad, over the Raton Mountains to Santa Fe. Albuquer que, down the Rio Grande. valley to Socorro, and then over the Continental ; Divide to Springer ville, Arizona,- through the Petri fied Forest, via Canyon Diablo, and the Grand Canyon, Needles as the Mojave Desert to Golden Southern , California and .

If the pressure is lower, the tire will flatten out more so that a larger area is on the ground. By-making the tire larger it is possible to have a larger area on the ground with out damage to the tire. It can flatten more and yet have ample space between the road and the tire rim, and on this account ; a balloon tire can operate with t a lower air pressure and the car cass need not be so thick or so strong. Being thinner, the casing will be more flexible, more pli able. . With an ordinary pneumatic tire If the air pressure is low and the tire very flat, the fabric In the tire is bent to a comparatively sharp angle and therefore the life of the fabric is short, and bend ing the fabric so much will also consume more power. If the tire is made larger, a larger area of tire can rest on the ground with out bending the tire fabric to such an extent. Since the pressure in a balloon tire is lower and the wall thinner it will absorb larger obstructions on the road Without raising the axle, than the ordinary pneumatic tire, and on account of its greater depth or larger amount of air in the tire, it will cushion the car more effectively. This is the reason a balloon tire rides more easily. On the other hand, should a sharp- stone.or nail, pro ject upward; let js .say more than half an im , . 'rrHo a :geater ex tent -than-"t'lfc.

This compressor attachment is similar to the supercharger as used for high altitude airplanes; compress ed air is forced into the intake manifold and results in a Super charged fuel air feeding the cylin dersv i ! v ; The result of the compressor's action' is an instant additional power impulse, amounting to more than 50 of the normal motor performance. For Instance, climb ing a steep hill with full power and a motor slowly decreasing in revolutions, a compressor-equipped car will suddenly leap forward with a roar and pick up new speed, after the normal maximum limit has been reached. ! SEAPLANES TO USE SAILS ; LONDON, Nov. 2 (AP) All metal seaplanes with masts and sails to fly are possibilities of the netar future, according to Dr. Wil helm Rohrbach, who lectured re cently before the Royal Society of Arts in London. He emphasized the safety and utility of seaplanes carrying sails, and said this fact might open a new era for naval seaplanes, as it meant they could sail at sea without using gasoline. OWsmobile with exhibit at Vir tually every, automobile show and salon during the 192a season, starting with the Twenty-fifth Sil ver Jubilee exhibit opening In New York City, January 2, fac tory officials announce. Last year Oldsmobile was represented at shows held In 143 cities in this country as well as several foreign salons. While figures are not available Olds Motor Works feels justified in making the claim that it has been represented at more auto mobile shows than any other manufacturer. The Olds Motor Works is the oldest automobile manufacturing company operating today, having been formed in 1897, more than three years prior to the advent or the first auto mobile showt The first year real production started 1900 saw 1400 of the famous little curved dash one cylinder "Merry Olds- mobiles", built and sold. . From the earliest days of auto mobile exhibits Oldsmobile has taken an active part in these dis plays, which did t much to foster : the popularity of. the motor car. Factory officials are of the opi- nin that these exhibits, even today when the, automobile has reached the high mark of being the second largest industry in. the country are, of untold value. "These exhibits perform the i same function for the automotive industry as do central markets and department stores In other lines of ' trade," said Thomas O'Brien, assistant sales manager of Olds Motor works. "By means i of the shows the public is given an opportunity in its natural de sire to shop around and see what is being offered. Many persons dislike shopping along "automo bile row" lowing to their being! importuned by salesmen every i time they enter a show room. At the show, however, they can look to their heart's content and seei just what the motor industry has to offer them. "Actual orders taken during the shows usually more than pay for any expense involved, but with out doubt thre or four times this number of immediate sales result from the annual exhibits in the weeks following. "Another important feature, is the . wholehearted support given these exhibitions by the news-1 papers of the country. This at-i titude clearly indicates that the editorial mind or America rightly places the automobile business at the top of the list or the country's essential industries. Anything that. gains, the undivided suport of ithe public press must be funda mentally sound." In addition to the various body types of the six cylinder Olds mobile, a cut-away chassis, show ing in detail every working part. will be included in most of the show exhibits of Oldsmobile dur ing the coming season. Dodge Brothers Motor Car owners know in advance what any service operation will cost' But they do not pay in advance for- service they may never need. That is because Dodge Brothers do not believe in so-called "free" service, which simply means that the selling, price of the car is so inflated that the;' " extra profit is sufficient to cover- ; "free" service costs.
