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.
