Abstract: A clutch and brake device for the impeller of a hydrodynamic device in which the clutch is engaged by selectively admitting pressure from a source of pressure to a clutch servomotor, this pressure being conducted to a release chamber for the brake servomotor to automatically release the brake, thus insuring proper timing of release of the brake and engagement of the clutch. The brake is applied by the charge pressure within the hydraulic torque converter which is applied to the opposite side of the piston for the brake with respect to the pressure from the source of pressure. Thus, when the pressure from the source of pressure is exhausted releasing the clutch, the charge pressure of the converter will automatically engage the brake. The charge pressure is also conducted to the release side of the piston for the clutch device, thus insuring the clutch will be fully released when the brake is engaged.

The cam means will induce a wedging engagement of the shoes upon further increase of speed. A spring is carried by each shoe urging them toward a disengaged position and retaining the shoes in the apertures.
