This invention provides an improved aircraft wheel rim wherein a demountable tire bead flange has an annular chamfer within the outboard end of the flange bore, and a split lockring which cooperates to maintain the flange on the wheel rim body has an outer surface chamfer which matches the flange bore chamfer, the angle of the flange bore and lockring surface chamfers being determined by the coefficient of friction of the material comprising the wheel rim assembly such that a compressive wedge-locking load force exists at the chamfer joint as may be imposed by inflation of a rim-mounted tire.

Configuration for demountable wheel rim flange/split lockring assemblies

A split retaining ring 60 locking a separable tire bead flange 14 on a wheel rim 10 has inboard 60a and outboard 60b facing portions and circumferentially aligned terminal ends 40, 50, each terminal end characterized by a drilled-through bore 46, 56 extending in the axial direction of the ring from the inboard facing portion to the outboard facing portion. A lockwire 70 is positioned through each drilled bore 46, 56 to retain the terminal ends 40, 50 of the split ring in a predetermined circumferential spaced-apart relationship.

Locking configuration for a wheel rim flange retaining ring

A foldable mast assembly for sailboats wherein a main mast is pivotably connected to a stub mast which is pivotally connected to a base secured to the sailboat deck. A removable pin extends between the stub mast and base whereby the main mast and stub mast may be folded to an inoperative position substantially parallel to the main deck and centered approximately lengthwise of the sailboat. The folding and raising of the main and stub masts are controlled by a cable reeved through sheaves carried on the main and stub masts, one end of the cable being connected to the fore deck near the bow of the sailboat and the other end connected to a power winch on the aft deck of the sailboat. In smaller sailboats, having small masts where cables and sheaves are not required, the folding and raising of the main and stub masts can be accomplished manually.
