ABSTRACT:
A safety device for an internal combustion engine powered implement and for disabling the operation of the internal combustion engine by means of a brake. The safety device includes a braking lever and a control lever which are both mounted on a single pivot member. Two springs are provided, the first of which normally urges the braking lever into contact with the flywheel of the internal combustion engine to prevent rotation thereof. The second spring biases the control lever into a rest position wherein the deadman control lever assumes its normal non-operated position and allows adjustment of control effort. The braking lever and control lever are mounted on the pivoting member by means of bushings to permit independent pivoting movement of the levers when the deadman lever is operated. The control lever contacts the braking lever by means of an abutment surface thereby rotating the braking lever out of contact with the flywheel and permitting the engine to operate. The braking lever also includes a protrusion for contacting an ignition circuit switch whereby the ignition circuit of the engine is also disabled in the rest position of the deadman control lever.
