  • Patent number: 4266770
    Abstract: A hand held counter particularly adapted for counting cards during games of Blackjack. The counter includes two lever arms mounted for incremental rotation on a vertical axle in a cylindrical casing. The cylindrical casing includes a circular faceplate having two circularly arced slots. The lever arms are each spring mounted against notches in the cylindrical side wall of the casing and have positioning pins extending through a respective one of the slots. The lever arms may be incrementally rotated in an arc defined by the limits of the slot by using the thumb of the hand holding the counter to push the positioning pins. Position pins arrayed along the outer circumferences of the slots permit the user to tactilely identify the relative positions of the positioning pins of the levers and to thereby identify the counts being made.
