  • Patent number: 5724955
    Abstract: An air compressed gun (10) is provided having a stock (11), a barrel (12), a trigger (13) and a manual air pump (14). The gun also has a magazine (18) having a series of barrels (26) for holding several projectiles (P). An actuator (50) indexes the magazine with each shot of the gun.

  • Patent number: 5709199
    Abstract: An air compressed gun (10) is provided having a stock (11), a barrel (12), a trigger (13) and a manual air pump (14). The gun also has a magazine (18) having a series of barrels (26) for holding several projectiles (P). An actuator (50) indexes the magazine with each shot of the gun and automatically controls bursts of pressurized air. The magazine has a mounting plate (25) with two concentric annular arrays of opening (28). A sealing plate (38) is configured to seal one opening with each sequential indexing of the magazine.

  • Patent number: 5707270
    Abstract: A firing post is generally positioned at the center of the top end of the body of a toy projectile to receive a percussion cap cartridge. The toy projectile has a soft outer body made of light-weight, pliable, compressible material such as polystyrene. The firing post and cartridge are covered with a nose of compressible material which generally houses a hammer and firing pin in alignment with the firing post. A spring-loaded hammer and firing pin is cocked by sliding the hammer through a housing for the hammer until a notch in the stem of the hammer is engaged by the top of the hammer housing. The trigger is a lever which is movable against the inclined top end of the hammer stem. The hammer and trigger assembly may be rotated with respect to a firing chamber placed over a multiple-cartridge mount to successively fire caps on the mount. A spring-loaded index helps facilitate alignment of the trigger-hammer assembly and holes in the firing chamber.

  • Patent number: 5699781
    Abstract: An air compressed gun (159) is provided having a stock (11), a barrel (12), a trigger (13) and a manual air pump (14). The gun also has a magazine (18) having a series of barrels (26) for holding several projectiles (P). An actuator (161) indexes the magazine with each shot of the gun and automatically controls bursts of pressurized air. The actuator has a manifold (162) having an inlet opening (163), an outlet opening (164) and a firing opening (166), and a piston (168) mounted within the manifold which directs the flow of air therethrough for sequential firing.

  • Patent number: 5553598
    Abstract: A plunger (34) directs pumped fluid through a conduit (40) into a piston sleeve (60) having a piston (66) that is reciprocally translatable within the piston sleeve (60). The conduit (40) terminates in a nozzle (49) which projects into one end, a posterior end, of the piston sleeve (60). The piston sleeve (60) also has a fluid passageway (62) connected with a fluid reservoir (50). A second nozzle (58) at the opposite end, an anterior end, of the piston sleeve (60) leads to a fluid passageway upon which a toy projectile (11) or similar object may be mounted. The piston (66) which is slidable within the piston sleeve (60) has a head (68, 69) at each end formed of compressible material such as soft rubber. A turret (70) enables several mounts (72) for toy projectiles (11) to be consecutively aligned for launching.

  • Patent number: 5499940
    Abstract: A system (10) simultaneously directs compressed fluid to a turbine while compressing fluid to disengage a locking mechanism that restrains movement of the toy vehicle (11). A primary tube (20), attached to the toy vehicle body (12), forms a primary chamber (22) which receives a plug in the form of a secondary tube (30) that seals the primary chamber (22). A fluid may be compressed into the primary chamber (22) through the inserted plug (30). The interior of the inserted tube (30) forms a secondary chamber (32) which encases a hollow piston (40). Fluid is compressed into the primary chamber (22) and secondary chamber (32) through the hollow piston (40). The hollow piston (40) also forms a part of a locking mechanism which maintains a latch (60), the primary tube (20) and the secondary tube (30) in contact with one another until pressurized fluid in the primary chamber (22) forces the piston (40) away from the latch (60).

  • Patent number: 5398873
    Abstract: A fluid pulsator (10) has a main housing (20) having an outlet conduit (24) projecting into a chamber (25) defined by the front of the main housing (20). A primary piston (30) is reciprocally translatable within the main housing (20) and has fluid conduits (34) for fluid flow through its body. A plunger (40) is spring-loaded and reciprocally translatable through the primary piston (30). The head (42) of the plunger abuts the front end of the primary piston (30) when the plunger (40) is in its retracted position. The main housing (20) has an abutment in the form of a flange (26) that defines the rearwardmost position of the primary piston (30). The main housing (20) contains a mechanism (21) for engaging the end of the plunger (40) so as to maintain the plunger (40) in its forwardmost position until released. Fluid flows (11) generally from the posterior portion of the main housing (20) through the primary piston (30) toward the anterior end.

  • Patent number: 5395275
    Abstract: A toy airplane and launcher assembly comprises a rubber band powered toy airplane having a propeller at its front end, a winding coupler disposed at its rear end, and a pair longitudinally aligned sleeves mounted to its belly. A rubber band extends between the propeller shaft and the winding coupler shaft. A pistol-shaped launcher includes a handle and with an elongated guide rod extending therefrom. The guide rod is sized to be received through the aligned sleeves of the airplane to mount the plane on the launcher and a latch releasable latches the plane in place when the guide rod is fully received through the sleeves. A coil spring extends about the guide rod and is progressively compressed as the plane is mounted on the launcher to catapult the plane from the launcher when the latch is released.
