Abstract
This invention relates to devices which can be mechanically actuated by the user for marking lottery and other game cards to indicate selected numbers. A shallow elongated container is provided in which the card to be marked is fixed in place. A U-shaped yoke fastened at one end of the container functions to pivotally support a tubular sleeve, which rotates up and down through a small angle against a spring bias. A shaft is interposed to be moved slideably in the sleeve in the lengthwise direction of the container. The shaft terminates at its inner end in a marking head, which is pivotally connected to move in a horizontal plane. A rod depending from the marking head supports stamping means which is constructed, when inked and depressed, to make an impression on the card to indicate a selected number. In one embodiment, the ink is stored in the marking head, and passes to the stamping means through a wick. In another embodiment, the marking head is solid; and the stamping means is inked by application to an ink pad, prior to being depressed to make a mark. Both embodiments include an additional container for storing spare cards.
