' ' { SATURDAY, CONFORT IN RIDING IS MAJOR PROBLEM Engineers Stadying New Methods For Easy Travelling. Automdtive engineers are giving serious scientific study to the rid- ing qualities of automobiles with a detéermindtion to find out what makes 'a ¢éar comfortable or uncom- fortable to ride in dnd to improve the riding characteristics. This is a complicated problem that involves physical effects, mental reactions and the physieal properties of springs, " JULY 18, 1920. tires, steering mechanisms and other parts of the vehicle, vibration and noise, and many other factors. Spring action, as comprised of Me springs, the "tires and the seat cushions, has most to do with rid- ing comfort. In a comprehensive paper on spring dynamics delivered at the semi-annual meeting of the Society of Automotive Engineers and printed in the July Issue of the sotlety's journal, O. C. Mock anal yzed the actiongjof simple singl: springs and of the combination o: front and rear springs on automo- biles.

The #nore flexible the spring the more efficient it is in decreasing the upward force agaainst the car body and the rate of increase of pressura against the passenger. The amount of force and its rate of application, wre increased markedly by either stiffness or friction in the springs. The best riding cars have a piteh- 'ng period of around or below 100 »er minute, while pitching motion etween 120 and 160 per minute is distinctly disagreeable. The coupe Ny Exploded!

HEAVY DUTY SPEED WAGON Is Announced by the Reo. Motor Car Company Considerable significance attaches to the announcement just made by the Reo Motor Car Company concerning the new Heavy Duty Speed Wagon, a vehicle designed to handle loads ap- proximately two tons. The purpose of the Heavy Duty Speed Wagon is to make available the factors of economy and fleetness for the hauling of loads which--by reascn of bulk or weight--are not suited to the Speed Wagon qualifications. An increased wheelbase, stronger springs and a heavier frame better adapt the Heavy Duty Speed Wagon to suth service as lumber hauling, furniture moving and other classes of carrying where added chassis length is desir able. That the Heavy Duty Speed Wagon can maintain fast schedules with pas- senger car smoothness is due to the use of a 6-cylinder engine, pneumatic cord tires and a spiral bevel gear drive. The same speeds when returning empty, without undue shock or jar to the chassis parts--a feature decidedly not present in the average 2.ton truck. It is a seeming paradox that any ve- hicle can travel faster when loaded than when empty; the explanation is that without the retarding influence of the load, vibration is allowed full play, and vibration is one of the greatest destructive forces in commercial car operation. In the Heavy Duty Speed Wagon, vibration is largely absorbed by the tires and springs, and finally by the doudble-frame--a distinctive Reo feature. Like all Reo products, the Heavy Duty Speed Wagon is designed and manufactured complete in the Reo shops--not merely assembled from parts supplied by different manufac- turers. The stated advantages include; better balancing of relative strengths, a single standard of quality, closer in- spections and centralization of respon- sibility. The 6-cylinder engine is husky and powerful, and of time-proved effici- ency. It has a 4-bearing crankshaft and a exceptionally large cooling area. A 13-plate clutch, large gears, smoothly operating spiral bevel gear drive, and a semi-floating axle--possessing the advantages of the full floating type without its disadvantages--are among the mechanical features deserving com. nient.

According to recent judgment in an appeal case, it is not. sufficient that a motorist signal that he is about to chdnge the direction, slow down or stop, but he must algo as- certain that the signal is observed by other users of the highway concern- ed. This was made clear by Mr. Jus- tice Orde. Just how a driver is to as- certain this drivers will ask in vain. The adjutant in charge of Canadian Mechanical Transport during the war hazards the opinion: "I suppose every blinking vehicle will have to be equipped with a radio receiving and broadcasting set now." Commenting on Mr. Justice Orde's declaration, Mr. Justice Middleton rémarked: "That is the maritime law; a signal is never assumed to be heard until it is answered." This comment was made in the appeal of Joseph Richechi from the decision of Judgé Gauld, awarding F. C. Cooper $120 dam- ages. Oné Sunday evening in Au- gust last, Richechi and family were driving from Beamsville to Hammil- ton. Mrs. Cooper was driving a family party in her husband's car from Hamilton to Beamsville, At a place where a private drive séemed an opportune place to turn, Mrs. Cooper cut in across the line of traffic. The Richechi car bumped the Cooper ear and both cars were damaged. Es Richechi sued for 120 damages. Céoper counter-claimed for a sim- {lar amount. The. case was tried by Judge Gauld. The plaintiff's action was dismissed and judgment enter. ed for Cooper at $120. bed ODBEDROTHERS SPECIAL SEDAN Observe the special equipment: bal- loon tires with steel disc wheels, nickeled radiator shell, front and rear bumpers, motometer with lock, wind- shield wiper, cowl lights, scuff plates and special body striping.
