Abstract

916,878. Linkwork. SVENSKA A.B. BROMSREGULATOR. Sept. 14, 1961 [Sept. 26, 1960], No. 33016/61. Class 80 (3). [Also in Group XXXIV] A mechanism for producing high and low leverage comprises a lever 1 possessing an abutment 6 determining the lower leverage and a coacting support abutment 7, one of the abutments being pivotally mounted, spring-loaded, and, in the brake release position, biased by the other abutment in the same direction as the spring loading. The spring yields to change the mutual positions of the abutments after the brakeapplying movement has commenced. The two abutments comprise a roller 6 and a spring- loaded member 7 having a curved roller track 13. A spring-loaded, pivoted lever 11 coacts with roller 6 and carries at its end a lever fulcrum 4 guided in a track 12 so that, after roller 6 has moved along roller track 13, lever 1 may pivot about fulcrum 4. The end of lever 1 pivotally attached to piston 2 is guided by a linkage 5. Specifications 542,805 and 565,814 are referred to.
