Claim 1
Independent Claim
242 words
In coupling means for interconnecting adjacently positioned pairs of a plurality of cargo-carrying pallets or containers in a serial formation to thereby facilitate the loading and unloading thereof into, and from the cargo comPartment of a delivery aircraft, said means comprising; first, permanently affixed, cargo-pallet or container-mounted block element means attached to the sides of said pallets or containers in adjacent and predeterminedly spaced-apart pairs, and further each incorporating a built-in and oppositely tapered slot, each corresponding, pairs of block element means being utilizable in attaching said adjacently-positioned pairs of pallets or containers to each other; and second, cargo-pallet or containerinterconnecting means for releasably attaching opposite sides of each adjacently positioned pair of pallets or containers and each including a relatively elongated and indirect cargo pallet or container-interconnecting-rod member extending in its normally mounted position between, in parallel and spaced-apart relation to, and over the upper surfaces of each of said pair of adjacently positioned pallets or containers, and a pair of intermediately positioned and relatively short, direct cargopallet or container-interconnecting-elements respectively extending from, and in depending relation to, the opposite ends of said rod member, each of said pair of depending elements comprising an interconnecting key member tapered in the same configuration as, and thereby being respectively engageable in locking relation within the built-in tapered slot of each of the block element means corresponding thereto for thereby automatically and positively ensuring correct alignment between adjacently positioned pairs of pallets or containers.

In coupling means for interconnecting adjacently positioned pairs of a plurality of cargo-carrying pallets or containers in a serial formation to thereby facilitate the loading and unloading thereof into, and from the cargo comPartment of a delivery aircraft, said means comprising; first, permanently affixed, cargo-pallet or container-mounted block element means attached to the sides of said pallets or containers in adjacent and predeterminedly spaced-apart pairs, and further each incorporating a built-in and oppositely tapered slot, each corresponding, pairs of block element means being utilizable in attaching said adjacently-positioned pairs of pallets or containers to each other; and second, cargo-pallet or containerinterconnecting means for releasably attaching opposite sides of each adjacently positioned pair of pallets or containers and each including a relatively elongated and indirect cargo pallet or container-interconnecting-rod member extending in its normally mounted position between, in parallel and spaced-apart relation to, and over the upper surfaces of each of said pair of adjacently positioned pallets or containers, and a pair of intermediately positioned and relatively short, direct cargopallet or container-interconnecting-elements respectively extending from, and in depending relation to, the opposite ends of said rod member, each of said pair of depending elements comprising an interconnecting key member tapered in the same configuration as, and thereby being respectively engageable in locking relation within the built-in tapered slot of each of the block element means corresponding thereto for thereby automatically and positively ensuring correct alignment between adjacently positioned pairs of pallets or containers.
Claim 3
Dependent Claim
72 words
In coupling means for interconnecting adjacently positioned pairs of a plurality of cargo-carrying pallets or containers in a serial formation as in claim 1, and a universal-type of joint-attachment means interconnected between the said rod member and the pair of depending elements respectively extending from the opposite ends thereof to thereby allow relative movement between adjacent pallets or containers during the serial loading or unloading thereof into, and from a cargo aircraft.
Claim 4
Dependent Claim
157 words
In coupling means for interconnecting adjacently positioned pairs of a plurality of cargo-carrying pallets or containers in a serial formation as in claim 2; said universal-type of joint-attachment means comprising combined hinge and swivel means including a rigid rod-end bearing member incorporating an integral straight link portion in its inner end and having an elongated inner passage telescopically positioned in snug-fitting relation to, and rigidly mounted on a necked-down portion on the opposite ends of the relatively elongated rod member, and a circular-shaped female, rod-end bearing member-support on its outer end; a spherical element positioned and revolvable in all directions within said female, rod-end bearing member-support and having a raised boss portion projecting outwardly of the said female bearing-support; and rigid attachment means positively mounting a spacer element and the upper end portion of each of said pair of depending elements in hinging and swiveling relation to the spherical element on each end of said rod member.
