  • De-clutch mechanism for valve operator
    Patent number: 4022309
    Abstract: A de-clutch mechanism is actuated, when the power is off, by manual actuation of a de-clutch lever shaft. When thus actuated, the de-clutch mechanism couples a rotatable driven sleeve to a handwheel drive and decouples the sleeve from the power drive. When the power is activated, the de-clutch mechanism automatically disconnects the handwheel drive. A typical application of the de-clutch mechanism is in valve operators.

  • Disconnect device for aircraft pitch or roll control system
    Patent number: 3964318
    Abstract: A device is disclosed by which two paired controls in an aircraft flight control system, such as pitch controls, or the roll controls, which are ordinarily operated in coordination by the pilot by use of a single operating control may, when the control on one side of the airplane is damaged and jammed, accomplish a disconnect of that side, and so free the opposite side control for operation. The aircraft can often be flown with just the one side control in commission, if freed from the opposite side. The device is in the nature of a bell crank, and the disconnect means is in the hub thereof.Also disclosed is a novel bi-directional sensor incorporated in the input arm of the bell crank, and which gives an indication to the pilot when the linkage to the corresponding control surface, or the control surface, is damaged and jammed. This sensor has application other than in aircraft control systems.

  • Gear changing mechanism
    Patent number: 3949848
    Abstract: A pair of bi-directional roller clutches are connected through outer races to separate gearsets and share a common inner race connected to a driven shaft. A shifting sleeve is slidably mounted on the common inner race and is selectively engagable with the retainers of the roller clutches, thereby locking the rollers of the engaged clutch in the freewheeling mode and releasing the rollers of the other clutch, allowing that clutch to drive through its associated gearset.
