Show SPRINGS 01 GARS M0STMHTM Haynes Light Six Finds Best Road Service in Semi-Elliptic Semi-Elliptic Construction. The adva ntages of the semi -elliptic spring are recognized by automobile de- signers loth in this country and in Europe, accordin.tr to A. F. Savage of the Haynes Motor Car company, distributer for the Haynes light six. who says: The semi-elliptic is so termed because be-cause it is a half-ellipse. It supports the frame of the car at either end and Is fastened to the axle housing at the middle of the spring. This construction con-struction allows extreme resiliency and ease of riding, at the same time preventing any side sway of the body on the chassis. The three-quarter elliptic spring is anchored to the frame of the car at the end and at the middle of the ellipse. The full-elliptic, is fastened only at the middle. Either of these types of construction permits a great deal of side sway of the body relative rela-tive to the chassis, which, of course, creates heavy strains and stresses detrimental to the entire car. The cantilever sprint:, which is really a one-quarter elliptic' spring, Is a feature which has been Incorporated Incor-porated In the design of several makes of cars. Cantilever springs, however, have not given such good satisfaction as either ha If -elliptic or three-quarter elliptic springs. The cantilever construction permits a wide side swing of the body on the chassis. On rough roads, where the -car is swaying from side to side, the cantilever equipped car will rock excessive! ex-cessive! v, sometimes making It difficult dif-ficult to hold the road. This, of course puts a great deal of unnecessary unnec-essary strain on the frame of the car, resulting in broken members and big repair bills. European designers are strongly in favor of seml-elliptfc springs, and "this type of spring is rapidly becoming a standard design In this country on all high-class cars. |
