Title: Explosively actuated release device for call buoys and the like

Abstract: An explosively actuated device for releasing a tongue bar from a clevised member embracing the tongue bar and having recessed portions aligned with a recessed portion of the tongue bar. A retaining block has a lower end normally in the recessed portions to lock the tongue bar and clevised member together and released therefrom when a cartridge is exploded to produce gases that build up pressure inside the block that moves the block. A retaining bolt secured to the tongue bar extends up inside the block and prevents the block from moving very far and holds it to the tongue bar. There is no fragmentation, and the retention strength is great.
