Abstract

341,412. Friction clutches. MECANO GES., 2, Grosse Gallusstrasse, and STEMPELWERK GES., 30, Cassellastrasse, Fechenheim, both in Frankfort-on-Main, Germany. Sept. 10, 1929, No. 27542. Convention date, April 4. [Class 80 (ii).] The presser-ring 8, Figs. 1 and 2, of a singleintermediate-plate clutch for motor vehicles is put into progressive engagement by a spring 3 acting through a sleeve 4, radial levers 5, and antagonistic weaker springs, which may be leaf springs 9 secured to a supplementary ring 6 and normally holding it apart from the main ring 8. Final pressure is applied positively by the levers 5. The ring 6 engages recesses in the ring 8 by radial arms 7 and the ends of the springs 9 lie between lugs 10 on the ring 8. The parts 6, 8 are retracted by further leaf springs 12, which bear on driving-pins 13 projecting from the flywheel 1 to engage and drive the ring 8. In a modification, the ring 6 is omitted and the levers 5 act directly, Fig. 3, or through sliding studs, Fig. 4 (not shown), on leaf springs 9 carried by the ring 8. Alternatively, they may act on cups containing coil springs, Fig. 5(not shown). In other forms, the springs 9, Fig. 6, act on the levers in the region of their pivots, the pivot holes 17 being elongated, or act on the pivot pins, the holes in the bearing-lugs being elongated. Specification 341,441 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a claim for a main or supplementary presser-ring constructed of independent segments. This subject-matter does not appear in the Specification as accepted.
