  • Patent number: 6808436
    Abstract: A aerial toy comprises a hollow sleeve member and a base member to receive and accommodate the hollow sleeve member longitudinally for sliding movement, the base member having a cap provided with a plurality of holes permit air entrance into the base member when it is pulled and an air insulation member bendably placed thereof inside the cap in a position opposite to the holes to prevent air exit from the base member when it is pushed to permit easy sliding of the base member along the hollow sleeve member while maintaining sufficient compressed air thereof. The aerial toy apparatus further comprises an air chamber into which the hollow sleeve member fits securely and a launch tube into which the air chamber fits securely to receive the compressed air from the hollow sleeve member and a flying member mountable onto an upper end of the launch tube to be pushed off of the apparatus by the compressed air released from the launch tube.

  • Patent number: 4883042
    Abstract: An air gun of the break-barrel type has a spring-urged piston working in a bore of a cylinder. The piston has two axially spaced latched cocking positions in the cylinder; an intermediate position in which the spring is only partially compressed, and a fully cocked position in which the spring is fully compressed. The piston is held in each of its latched positions by the co-operation, in turn, of a sear with a one of a pair of axially spaced grooves in the piston. Initial downward swivelling of the barrel causes a cocking bar pivotally connected to the barrel to engage in the rearward groove and force the piston backwards to its intermediate position. The gun can then be fired with reduced power or alternatively a second cocking stroke performed in which the cocking bar engages in the forward groove and urges the piston to its fully cocked position. Instead of having a breaking breech, the gun may operate by a cocking lever. The piston may have more than one latch intermediate position in the bore.

  • Patent number: 4759336
    Abstract: An underwater speargun consisting of two spears that are independent of each other. This underwater speargun is capable of 2 rapid discharges of spears or 2 simultaneous discharges of spears. Accidental firing is prevented due to the safety blocking the trigger until the trigger and the safety trigger are squeezed rearward at the same time. Grooved tracks and front spear guides help insure the spear propels out of the gun in a straight path.

  • Patent number: 4676504
    Abstract: Ball dispensing apparatus for hitting practice includes a ball retainer for retaining and sequentially delivering balls to one end thereof, a lever rotatably mounted on a shaft at the one end of the retainer for engaging and lifting a ball from the retainer upon rotation of the lever, and an actuator for the lever for causing the lever to engage, lift, and project a ball from the retainer. A spring is attached to the retainer and to the shaft for accelerating the rotation of the lever into engagement with the ball. The tension of the spring can be varied thereby varying the trajectory of a ball lifted from the retainer.
