Abstract: A control device for a boat engine, capable of controlling both clutch and throttle with a single lever. The control device has a supporting shaft installed within a housing. A clutch arm, an operating disk and a throttle arm are rotatably mounted on the supporting shaft in such order. The root portion of the operating lever radially extending through a slit of a peripheral portion of the housing is fixed to the periphery of the operating disk. The control device has a gear mechanism and a cam-link mechanism. The gear mechanism changes the first stage turning of the operating disk to a swing movement of the clutch arm, and then, locks the clutch arm after the clutch arm has been swung to an end position. The cam-link mechanism prevents swing movement of the throttle arm during the first turning stage of the operating disk and also provides a swing movement of the throttle arm during the latter turning stage of the operating disk.

Abstract: A means for controlling a rotor of a helicopter utilizes cyclic pitch chas to its rotor blades, accomplished with a cyclic control stick. Cyclic control sticks have been a matter of concern in crashing situations. Prior art cyclic sticks are hinged to that they can be pulled out of the way of a pilot thrown forward and down by an impact. A lanyard actuated by the movement of the pilot's seat pulls the cyclic stick away from the pilot. Since such systems require various mechanisms and pulleys there is a need for an improved cyclic stick. A crashworthy cyclic control stick which is pilot actuated to overcome these difficulties is provided herein.
