Abstract: A self-retracting bomb suspension lug assembly for being releasably supported by a hook or the like of an airplane bomb rack. The lug is mounted within a housing for axial movement and has an outer surface conforming to the shape of the bomb so as to eliminate aerodynamic drag when the bomb is released. Springs, such as a stack of Belleville springs, are disposed for biasing the lug inward when the bomb is released and the weight of the bomb no longer bears on the lug. Finger springs and pawls engagable with a groove in the bottom surface of the lug are provided to maintain the lug in partially extended loading position wherein the top of the lug is accessible for being grasped. To cock the lug, it is moved slightly inward against the force of the lug biasing spring, and the finger springs are forced radially inward to engage the groove.

Abstract: A surface minelaying system that can be built up of ganged modules and rapidly mounted on any ship whose displacement permits it to carry mines in some quantity. This minelaying system is a modularized overhead conveyor system that can securely store heavy mines and safely release them overboard at short, predetermined intervals, even in high sea states. The system comprises a frame member, with first and second ends, that defines the longitudinal axis of the minelaying system. The frame member is preferably made up of a rail track braced by periodically spaced vertical and transverse connecting members. Mounting supports are provided for mounting the frame member to the ship. A drive roller and an idler roller are disposed in the first and second ends of the frame member; and an endless drive member is looped about the rollers. A drive means is operatively coupled to the drive roller.
