ABSTRACT:
A resettable release device to replace a shear pin connection between two members comprises a drive ball yieldably held in a seating in one of the members by a plunger slidable in a housing in the other member. The drive ball is located in a bore in the housing. The plunger has an annular shoulder against which a crowded ring of detent balls is held by two ball control rings resiliently urged towards each other. On overload, the drive ball moves out of its seating by pushing the detent balls up over the shoulder, forcing ball control rings apart. Pushing the plunger back to its original position resets the device.
