  • Patent number: 4130281
    Abstract: A horseshoe pitching game apparatus having a court with a player station at one end, a horseshoe receiver assembly with a pit and a stake at the other end, and a lane between the station and pit assembly. A device is provided for traveling over the pit to pick up the pitched shoes and place them on the conveyor to be returned to the player station, and also smooths the material in the pit for the next pitch. A TV camera in conjunction with a computer may be used to determine whether the pitch is valid, and thereafter report the score on a screen or other suitable readout screen or sheet. Electrical magnets are preferably used to lift the shoes from the pit and to drop them on the conveyor for returning them to the station, and a backboard and sides are preferably responsive to contact by the shoes to indicate whether the shoes are legal or illegal pitches.
