ABSTRACT:
This device for jettisoning a load in two completely different ways comprises a rocker fulcrumed on a support rigid with the load, or spherical member formed integrally with the support, and a pair of opposed hooks fulcrumed to the structure from which the load is to be suspended, these hooks being responsive to separate control members, so that when only one hook is retracted the load can be released. If a spherical member is used, sliding cylindrical members having opposed ends formed with spherical concavities matching the curvature of the spherical member are provided, so that retracting one or both sliding members will release the load.
