A linearly traveling handle is employed in the operations of both a firing mechanism and an advancement mechanism. A novel indexing mechanism utilizes a series of drive surfaces and alignment channels on a rotary element to allow a single advancement drive member, such as a pawl, to induce precise sequential alignment between a plurality of launching barrels and a firing mechanism, without the need for additional indexing members.Field of SearchMagazineRotary FLUID PRESSURE Having common supply to plural projector barrels Provided by movement of user-actuated, projector-mounted pressure member To create surge of pressure By plunger moving within cylinder By spring-driven plunger Within cylinder having diameter larger than projector barrel | |
