  • Wild turkey call
    Patent number: 4576584
    Abstract: A turkey call capable of realistically imitating both the gobbling and clucking sounds made by wild turkeys. A hollow body has an internal sound chamber covered at one end by a vibratile diaphragm. An air bulb is mounted on the opposite end of the body and can be squeezed to vary the gobbling sound produced by the diaphragm. A hammer and anvil mechanism in the sound chamber reproduces the clucking sounds made by wild turkeys and can be activated independently of the diaphragm.
