Abstract: A locking device includes an annular locking face formed on the inner surface of a casing and an annular lockable face opposed to the locking face and provided on a driven member turnably mounted on the casing. The lockable face is movable into pressing contact with the locking face to lock a lever when the lever is rotated and thereby screwed in toward one direction longitudinally thereof. The locking face and the lockable face are operable free of any local uneven wear, while the lever can be locked to the desired position and unlocked therefrom with high reliability at all times.

Abstract: In an intermittent transmission meshing mechanism comprising a toothed drive member having a toothed portion and a circular outer periphery continuous therewith and a toothed driven member having a toothed portion and arcuate locking faces formed on the opposite sides thereof, an oil retaining member having a projection projecting toward the drive member is provided on the driven member between the toothed portion thereof and each of the locking faces or on each of the locking faces. When an end of the circular outer periphery of the drive member adjacent its toothed portion comes into sliding contact with the toothed portion or locking face of the driven member, the corresponding oil retaining member slightly presses against and applies lubricant to the end.

Abstract: A device for the removal of ice fixed to a rod of a control cable, which comprises a tubular fitting having at its opening a deicing surface including at least one sharp-pointed portion and inclined with respect to the axis of the rod, the tubular fitting being secured onto the end of a guide pipe in which the rod connected to an inner cable is slidably disposed. The device can remove the ice automatically with a small operational power by operating the inner cable.

Abstract: A single lever clutch and throttle control which in normal operation assures that the throttle is held out of operation until the clutch is completely engaged and further assures that the clutch is held in the engaged position during operation of the throttle. An engine warm up mode allows operation of the throttle while the clutch is held disengaged.

Abstract: In a two-lever control unit including a shaft mounted on the main body of the unit, a clutch operating plate and a throttle operating plate both rotatably supported by the shaft, a clutch lever for moving the clutch operating plate and a throttle lever for moving the throttle operating plate, a locking pin extends through a bore in the main body and has one end engageable in three locking cavities formed in the clutch operating plate and the other end engageable in a locking cavity formed in the throttle operating plate. One of the operating plates, when turned, causes the locking pin to lock the other operating plate. Thus, the clutch lever, when operated, locks the throttle lever, whereas when the throttle lever is operated, the clutch lever is locked. This simple structure gives the control unit greatly improved safety.

Abstract: A control unit comprising a casing, a drive shaft rotatably supported by the casing, a lever having a boss secured to the drive shaft, a shift rod extending through the boss and slidably inserted in a bore of the drive shaft, the shift rod being biased by a spring in a returning direction, a locking ring turnably supported on the outer periphery of the drive shaft, a drive gear rotatably supported by the drive shaft and having a toothed portion on part thereof and a circular outer peripheral surface continuous with the toothed portion, a driven gear rotatable by the drive gear, a drive plate having a drive pin implanted therein, a throttle cam having a specified cam groove receiving the drive pin therein and mounted on a pin on the driven gear movably in a direction at right angles to the drive shaft, a clutch arm having a clutch cable pivoted thereto, and a throttle arm having a throttle cable pivoted thereto.
