Abstract
A compact one-handed thumb actuated friction type turkey call is formed generally of a rectangular, elongated hollow wooden sound chamber box assembly having longitudinally opposed side walls with a double longitudinally convex bottomed striker pivotally mounted to one end block at one end thereof for oscillation across the sound chambers opposed walls. The striker having the end opposite of the pivotal mount cut at an angle and having a rectangular shaped thumb tab affixed to the flat upper side angle cut end is actuated by the operator by holding the call across ones palm and pushing the thumb tab. A closed, looped, stretchable band biases the striker back to an open position which is slightly unparallel to the position of the sound chamber box when in the open position.
Claims31
A compact hand operated, friction type, box call comprising:
- a generally rectangular, elongated hollow wooden sound box forming internally a sound chamber, said sound box comprising a base connecting to a front end wall connecting a pair of spaced apart parallel contactable side walls to a back end wall;
- a striker lid comprising a generally rectangular, elongated planar member for cooperatively engaging said hollow wooden sound box, said elongated planar member defining a top flat surface and a bottom double longitudinally convex surface, said planar member having a generally rectangular front end and an opposing end including an angular portion;
- a tab mounted to said top flat surface of said striker lid;
- means for pivotal mounting said striker lid for pivotal movement across the open top of said sound box, against and perpendicular to, the longitudinal axis of a selected contactable wall of said sound box;
- compression means for holding said striker lid a selected and adjustable distance from said sound box where said striker lid is pivotally mounted to said sound box;
- means for holding projecting from said bottom surface of said striker lid limiting pivotal movement thereof;
- said side wall of said sound box opposite said angular portion of said striker lid including an opening in alignment with said means for holding;
- and
- means of biasing said striker lid against a contactable wall of said sound box for resisting movement of said striker across said contactable wall of said sound box and normally biasing said striker lid into a position slightly unparallel to said sound box.
