Abstract
A chain saw safety brake mechanism includes an actuating drum rotatably disposed around the periphery of a clutch drum and a brake band wound around the clutch drum at least one convolution and hooked at one of its ends its other actuating drum and attached to the other end to a chain saw body. A spring is provided for turning the actuating drum from its ready position to a brake actuating position in which the brake band is tightened around the clutch drum to arrest its rotation. A reset lever is provided on the actuating drum to turn it to the ready position thereby producing a spring force in the spring.
