ABSTRACT:
The improved motion-amplifying lever arrangement includes a pair of cooperating lobe members for effecting a mechanical advantage between the operating lever and an output cable during pivotal movement of the lever from an inoperative first position toward an operative second position, use being made of a spring clutch associated with the drive cam member for locking the lever in he brake-applied position, and a self-adjust device associated with the driven lobe cam member for removing cable slack when the operating lever is in the inoperative first position. In the preferred embodiment, the lobe members comprise lobe cams that are connected by a flexible strap of belt that extends between the cooperating cam surfaces and is secured at opposite ends to the cams, respectively.
