Abstract: The top of a ring-like film forming member with an opening receives bubble solution and gravity causes the solution to flow over the protruding surface of a movable member within the opening such that the surface tension of the bubble solution causes a film to form within the opening and over the surface. The movable member is moved out of the way to allow wind from a wind supply to reach the rear of the ring-like member to form and release a bubble. The protruding shape of the surface allows the film to form and in intact as the member is moved. A trigger mechanically connected to the movable member controls the position of the movable member and the energization of the motor which drives the bubble solution supply and the wind supply. Continuous depression of the trigger causes a series of bubbles to be formed and released.

Abstract: One embodiment of a football throwing machine using an axially aligned compression spring for propulsion and a latching mechanism for retaining the spring in its compressed state. A spiral shaped actuator mechanism is used to compress the spring with consistent torque throughout the compression stroke. The spring is released from its compressed state using an efficient triggering mechanism. A timing mechanism allows a delay so the user can position for the catch. The football is held by axially misaligned wheels on one end and a rotating cup on the other. As the spring pushes the ball between the wheels while being ejected from the apparatus, the wheel misalignment causes the helical spinning effect on the football while the cup holding the other end of the football spins freely.

Abstract: A cylindrical toy rocket that measures at least 8-inches long and 2½ inches in diameter. The rocket has a weighted rubber nose cone that is mounted on an inner slide tube that fits inside the rocket's main body tube in contact with a compression spring. At least three guide fins are attached to the outside bottom of the rocket's main body tube. The rocket is launched by means of an attached tether and gripping handle. In use, the handle is gripped in the hand of the player and swung in a vertical circular motion starting in an upward direction. The rocket is then released such that it is catapulted upward into the sky along an initial flight path. When the rocket reaches its apex and starts a descent, the heavier nose cone will assume a downward position. Upon impact with the ground, the nose cone and inner sliding tube are forced into the main tube body of the rocket, thereby compressing and storing potential energy in the spring.

Abstract: A mechanical hand grenade launcher comprised of a launch tube and spring-ven plunger for propelling a hand grenade to a target area. At the aft end of the launcher is a charging handle that when pulled rearward compresses a spring within the launcher tube. When the spring has been sufficiently compressed, the spring is then locked in the cocked position by a safety pin attached to a first lanyard. A hand grenade is loaded through the fore end of the launcher and the grenade's pull pin is attached to a second lanyard. When rearward force is applied to the second lanyard, the grenade pull pin is dislodged from the grenade. To launch the grenade, rearward force is applied to the first lanyard dislodging the safety pin which releases the spring. The force of the expanding spring imparted to the hand grenade propels the hand grenade out of the fore end of the launch tube toward the target area.

Abstract: A projectile launching device is disclosed herein having, in its simplest form, a single elongated launching tube or barrel, onto the rearward end of which is pivotally mounted a lever assembly having a latch member and a release member coupled to one another about the pivot. The release member extends across the rearward end of the barrel and the latch member extends forwardly along the barrel. The barrel is open at its forward end to receive a shaftlike projectile. A hook is carried at the forward end of the latch member to protrude through a slot radially into the barrel for engagement with a tab on the projectile shaft. A spring, housed inside the barrel, rests against the release member of the lever assembly such that when a projectile is inserted into the barrel it compresses the spring against the release member and pivots the lever assembly to force the hook into the barrel and into engagement with the projectile tab, thereby preventing the spring from ejecting the projectile from the barrel.
