  • Patent number: 6647975
    Abstract: The invention relates to a ball projecting apparatus having a ball singulator with a fork-and-actuator mechanism that is adjustable to allow the apparatus to be used for a variety of different sports. A fork assembly is adjustable or replaceable to convert the apparatus from use with balls of one sport to use with balls of a different sport. Each fork may be referred to as a “rocker,” since it is pivoted from a first position in which a foremost ball is impeded from advancing to a second position in which the foremost ball is released, but the next ball is impeded. The rocking motion alternates which of two prongs is within the ball-supply path. When the forward prong is in the ball-supply path, all balls are prevented from advancing. Alternatively, when the rearward prong is in the ball-supply path, the foremost ball is allowed to advance.

An open container is disposed on the second hollow tube for holding the end of the flexible line therein. A spring member resides within the tubes and extends through telescopically overlapping sections of the tubes. A user inserts the end of a fishing line into the open container with a lure or bait attached to the end of the line, pulls the second tube backwardly against the spring member and releases the second tube, thereby permitting the spring member to thrust and second tube forwardly and launch the end of the line through the air.

  • Patent number: 5690089
    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.

  • Patent number: 5619977
    Abstract: A ball throwing apparatus includes an enclosure formed with an aperture and a movable gate to cover the aperture. A throwing arm adapted to receive a ball is pivotally mounted within the enclosure for movement between a ball loading position and a released position. A suction cup element holds the throwing arm in the ball loading position and releases the throwing arm from the ball loading position after a time delay. When released, the throwing arm is biased by a spring to move from the ball loading position to the released position to throw the ball. At the same time, movement of the throwing arm acts to open the gate to allow discharge of the ball from the enclosure. The use of a gate makes the ball throwing apparatus safer by enclosing the moving parts of the apparatus to make them inaccessible when in use.

  • Patent number: 5613482
    Abstract: A spring-powered toy gun ejects small disks, of the type children collect, giving the ejected disks a spin to improve their flight. The disks are first loaded into a separate spring-operated magazine which is then inserted into an aperture on the gun. A transparent window in the gun allows a user to view the magazine's top disk and any insignia thereon. The top of the magazine bears two retaining members that hold the top disk in place. These retaining members are spaced apart from the magazine by the thickness of one disk and, thus, set the thickness of the disks that can be fired from the gun. The top disk is ejected from the gun by a planar propulsion lever driven by a main spring. Pulling back on a trigger moves the main spring and the propulsion lever away from a rest position. When the trigger is pulled fully, the main spring is automatically released and snaps forward causing the propulsion lever to move forward and strike the top disk propelling it from the gun.

  • Patent number: 5597160
    Abstract: An apparatus for baseball batting training. The apparatus includes a rigid-wall cylindrical tube with means to support a baseball at one end thereof. A striker movable within the tube, is latched against a preselected force of a coil spring, and is rapidly urged toward the baseball for impingement therewith to propel the baseball upward a distance corresponding to the preselected force of the spring. When the striker is pushed down, a pin is visually extended and retracted to engage a selected one of a plurality of latching detentes to hold the striker in a cocked position. Upon release of the pin, the spring loaded striker is urged rapidly upward to impact with the baseball and propel the baseball into the hitting zone of a waiting batter. The inside diameter of the rigid-wall tube is larger than the small end of a baseball bat to allow the bat to be pushed into the tube and reset the apparatus for another use.
