Abstract: There is disclosed a cargo restraint for palletized cargo which is detachably secured to rails or frame members such as a conventional seat rail in an aircraft cargo hold. The restraint includes a frame and a folding assembly of a pawl plate member with fore and aft folding support links therefor whereby the pawl plate member can be folded into a retracted position, within the confines of the frame and elevated therefrom into an elevated, cargo pallet engaging position. The pawl plate member extends fore and aft of the support links to restrain the edges of adjacent cargo pallets. The frame is provided with a transverse web immediately forward of the support links to serve as an abutment stop therefor, restraining the links in the extended position and accommodating high acceleration forces in a forward direction. The assembly is provided with a resilient springs to urge it into the retracted position and a locking member secures the assembly in the extended position against the bias of the resilient springs.

Abstract: A roller assembly useful as a self-aligning caster for recessed mounting in a support plate or tray such as those used in aircraft cargo loading systems. The assembly includes a sub-assembly of a cup housing having an upper, outer-annular flange with a roller support mounted therein on an annular bearing. The sub-assembly is secured by a single screw fastener that extends through a central aperture in the bottom wall of the housing and engages a ring retainer. The roller support has massive, upright standards which are spaced apart by the width of the roller and which have opposed slots in their upper faces to receive the support shaft of the roller. The roller and support shaft are received in the support base and are retained therein by a cover plate that has a radial slot to surround the roller and that overlies the roller shaft notches of the upright standards.
