Abstract: The present disclosure describes a multi-stroke parking brake control that includes a pulley connected to a parking brake cable and a brake pedal arranged to drive the pulley. The pulley has a large gear in mesh engagement with a driving pinion supported by the brake pedal and a holding pinion supported by the control housing. A one-way helical spring clutch drivingly interconnects the driving pinion and the pedal when the pedal is moved in a direction to tension the brake cable. A similar spring cable interconnects the holding pinion and the housing and functions to hold the gear and pulley in a brake applied condition. A release mechanism is arranged to release the second one-way helical spring clutch to permit the pulley and brake cable to move to a released position under the force of a release spring. This construction of a parking brake control permits the brake pedal to be stroked a plurality of times to tension the brake cable as desired.

Abstract: According to the present disclosure, a multi-stroke parking brake control has a pulley connected to a parking brake cable, a slidable actuating rod and connecting means constructed to drive the pulley when the rod is displaced. A gear is rotatably supported on the pulley and is in mesh engagement with a toothed rack formed on the rod. A one-way helical spring clutch drivingly interconnects the pulley and the gear in response to rotation of the gear caused by movement of the rod in a direction to tension the brake cable. A second one-way helical spring clutch interconnects the pulley and the housing and functions to hold the pulley in a brake applied condition. A release mechanism is arranged to release the second helical spring clutch to permit the pulley and cable to move to a released position under the force of a release spring. This construction of a parking brake control permits the actuating rod to be stroked a plurality of times to tension the brake cable as desired.
