  • Braking device for a motor saw
    Patent number: 5503255
    Abstract: A braking device for a motor saw including a rotatable brake drum (11), a brake band (12) surrounding the brake drum and actuatable by a spring (26) which is adapted to stretch the brake band around the brake drum, and a toggle joint mechanism (18,20) adapted to release the brake band from the drum against the action of the spring and to latch the braking device in an operating position in which the brake band is released from the brake drum. The toggle joint mechanism is actuatable by a control means (16) for adjusting the position of the brake band. The toggle joint mechanism is adapted, in the case of rupture of the brake band, to be adjusted by the spring to a position in which re-adjustment of the control means to the operating position is prevented.
