Rotation is transmitted by belt 3 between pulleys 9 and 10 which rotate about fixed axes B and A. Brake-drum 7 is rigidly secured to pulley 9. One end of brake-band 8 is attached to link 5 and the other end to circular eccentric 6 which turns about fixed axis E. Brake-band 8 encircles brake-drum 7 and eccentric 6. To brake and stop pulley 9, lever 1 is turned clockwise about fixed axis D. This withdraws idler pulley 2 from belt 3 and advances lever 5 on which pawl 4 is attached. Pawl 4 pushes against pin a in eccentric 6 and turns it, thereby tightening brake-band 8 on brake-drum 7 to quickly stop pulley 9.
