.STUDEBAKER STYLE TRANSMISSION BEST
 ENGINEERS KNOW
1ntermediately Located and Connected to Clutch by
 Double Thermoid- Hardy Coupling

In designing the three new Ser es IS Studebaker cars, Studebaker engineers were not bound down to any hard and fast rules. No one's pet theory was allowed to dominate the plans for the various units of the new cars. Every one, however, including some of the best and ablest engineering talent in America, was required to set down, as if he were to design car for his own personal use. specifications for con sideration in working out the plans for the Series 19 Studebakers. As a result of these deliberations, and months of plans were evolved that represented the best that engineers know. Experi- mental models were then built and put on road speedway for the famous Studebaker 40,00o-mile endurance test the most rigid test known to automo- bile history.
 The intermedately located transmits sion of the new Studebaker cars stands out, perhaps. as one of the most con spicuous examples of the greaN care and thought given the construction of each unit of the new Studebaker cars. 1t Is located just back of the clutch and is connected with the clutch by means of a double Thermoid Hardy flexible coupling.
 There are four Timken bearings in the Studebaker transmission and each bearing has the splendid mechanical advantage of being adjustable to wear And, instead of the four -jawed or. dog coupling ordinarily used. the second speed gear is cut with internal teeth which act as clutch engaging with the main drive pinion when in high gear. The result of this unique con struction means that there is never any difficulty in shifting into high. and easy, quiet gear changing is effected with a total absence of the usual clash ing of gears. The new Studebaker clutch brake still further aids toward this end, automatically checking the speed of the clutch when the latter is released
 The transmission itself is supported by subframe-a feature new to Amer ican practice and used only on one or two Of the highest priced cars-which also carries the rear of the motor. By this arrangement the benefits of unit power plant rigidity are obtained with out the additional cost, weight and in- accessibility of bell housing and with added fexibility, gained from the f1exi- ble couplings.
 Anu these HeXfDle dlSkS or sea island cotton mean much to the successful op- eration of the COTS mechanism. A mi nor unit of construction. to be sure but contributing in no small measure to the success of the new Studebakers and to the comfort, both mental and physical, of the owner. These flexible couplings are composed of two large nbre disks. They take the place of a universal joint and smooth out the DOW CT impulses of the motor. These disks are built up from six layers of the highest quality of sea island duck, rub herized, and laid in staggered construc- ton for greater strength. Besides pro- Flding flexible member between mo- tor and transmission, taking care of any misalignment between these harts. the Thermoid- Hardy coupling acts as a cushion, preventing the resonance usual to those parts when they are built as unit with the motor with a bell housing.
