  • Target throwing apparatus
    Patent number: 4672942
    Abstract: An apparatus for propelling metal cans into the air for target use with a BB gun utilizes a motor-driven launching wheel having a resilient perimeter, and a gripping surface spaced apart from the perimeter by a distance equal to the diameter of the can to be launched. A downwardly inclined feed ramp sends cans to a launching arm which is raised by a solenoid so as to place the can between the wheel and gripping surface.
