  • Game call mouth positioner and tone tuner
    Publication number: 20120028536
    Abstract: A game call device that helps position a user's mouth over a reed call and select the call tone desired. An elastomeric cap with a reed aperture fits snugly over a reed assembly. The cap helps the user find the right position for the mouth and lips. The rubber cap helps the user to press down on the reed and reed assembly to change the pressure on the reed and the space created by the cap's cavity. Tone or pitch holes in the cap allow the user to close the holes with the user's fingers or mouth and further adjust the tone and pitch of the call.

  • Game call tone selector
    Publication number: 20110207380
    Abstract: A game call tone selector that allows the user to change the tone, pitch and volume of a game call. A movable cap is disposed over the rim of a game calls sound chamber. Openings in the cap's lip and the sound chamber's rim may be aligned and fully open, partially aligned and partially open, or unaligned and fully closed, altering the tone, pitch and volume of the call. The game call further discloses a flexible call pipe that may be retracted within a larger bugle tube, thereby providing a game call that is compact, easy to carry, and can be used hands-free while deploying a gun or bow.

  • Game call apparatus
    Patent number: 5520567
    Abstract: A game call in the form of a diaphragm call includes an upwardly extending shelf which extends over a substantial portion of the latex membrane. The shelf provides a constant distance above the latex membrane to render the call easier to use and prevent the caller from damaging the latex membrane from upward pressure by the tongue. The shelf may be adjusted to vary the distance between the shelf and top surface of the latex membrane.
