751,286. Friction clutches. DANA CORPORATION. May 19, 1954 [July 20, 1953], No. 14656/54. Class 80(2) The two spring-engaged clutches A, B of a double friction clutch are controlled by a single pedal or lever operating a slidable sleeve 33 which acts, through a single set of radial levers 37 pivoted on a back plate 40 secured to the driving flywheel 10 on a single set of disengaging rods 30. The driven disc 14 of clutch A, splined to a first output shaft 25, is normally engaged between the flywheel 10 and a presser plate 12 rotating therewith by a spring disc 15 acting between plate 12 and an abutment plate 20 fixed to flywheel 10. The driven disc 47 of clutch B, splined to a second output shaft 31, is normally engaged between plate 20 and a presser plate 45 rotating therewith by a spring disc 59 acting between plates 40, 45. In Fig. 1, rods 30 act directly on plate 12, while adjustable studs 64 are interposed between plates 12, 45, so that clutch A disengages first, followed by clutch B. In Fig. 3, the rods act directly on plate 45 through adjustable nuts 64' and act on plate 12 with lost-motion at 24', so that clutch B disengages first, followed by clutch A. The nuts 64<SP>1</SP> may, however, be so adjusted that the clutches disengage in the reverse order or simultaneously.
