Abstract
A pneumatically or hydraulically operated clutch brake assembly for coupling a load to a motor is disclosed. The clutch brake assembly comprises a main body, an input shaft rotatably mounted on the main body, a drive disc mounted on the input shaft, an output shaft mounted for rotation and for a limited axial movement on the main body, a driven disc mounted on the output shaft, a first friction shoe mounted on the main body facing one face of the driven disc, a second friction shoe mounted on the driving disc facing the other face of the driven disc, spring means mounted on the main body for biasing the driven disc into engagement with the first friction shoe, and means for mounting a portion of a flexible conduit on the main body, whereby expansion of the flexible conduit portion, when pressurized fluid is present in such conduit portion, will cause movement of the driven disc from engagement with the first friction shoe into engagement with the second friction shoe, thereby coupling the motor to the output shaft.
