ABSTRACT:
A unidirectional drive tool cartridge for use as a torque transmitting device which includes a housing within which is mounted a unidirectional continuous clutch and drive shaft assembly. The drive shaft is carried within a bearing member located within a clutch. The bearing member has a central opening configured to receive a shoulder portion of the drive shaft so that the drive shaft may be slidably moved along an axis of its rotation within the bearing element and may be rotatably drive by the bearing element around the axis of rotation. Front and back faces of the housing are provided to constrain the longitudinal movement of the drive shaft therein. By virtue of the operation of the unidirectional clutch, the drive shaft may be driven in one direction on rotation of the head and is not driven in an opposite rotation of the head. The drive shaft is selectively movable within the housing to extend from either rotational direction, depending upon the direction of extension of the drive shaft therefrom. In this manner the unidirectional drive cartridge may be secured to a myriad of conventional torque application members such as wrenches or the like and/or in replacement of worn or broken ratchet assemblies.
