WoodrowAttorney, Agent or FirmInternational ClassF41B 011/00AbstractA dual mode ammunition loading air or gas-powered gun. The gun is conceived for shooting manually loaded small bullets shot by shot, or for alternatively acting as a repeating weapon for spherical ammunition (2) fed from a loader (4), dispensed one by one into a pocket (9) of an ammunition shifting body (8) mounted in a sliding arrangement, perpendicular to the barrel (3), so as to shift the ammunition up to a position in coalignment with the barrel (3) and with an air/gas delivery hole (17), of a compression chamber. The trigger (18) of the gun, is pin-jointed with a drawing member (19) spring-loaded at one (19a) of its ends and whose other end (19b) is connected to the striking hammer (21) for its cocking and ulterior release. The shifting body (8) is linked with the trigger through an assoicated lever (23) whose first end (23a) is rotatably pin-jointed with said trigger (18) and whose other end (23b) is hinged connected with said shifting body (8). A filter block (41) made of a porous material is located between the outlet of a reservoir (29) and the chamber (39).Field of SearchWith control for discharge of fluid pressureFor continual projection of successive projectiles (e.g., for "rapid fire", etc.) By valve means For discharge of pressure from removably mounted cartridge Opened by fluid pressure-actuated means Trigger or releasing mechanism Plunger release Projectile holder or carrier Mechanical projectile feed Spring | |
