Variably tensionable diaphragm game call
First Claim
1. A variably tensionable diaphragm game call comprising a frame and at least one diaphragm mounted in said frame, and means associated with said frame for selectively varying the tension of said diaphragm, said frame being U-shaped, with a cross-piece connecting spaced, generally parallel leg members between which said diaphragm extends, at least one of said leg member having a surface of substantial width between respective inboard and outboard edges of said leg member, said diaphragm being mounted at said outboard edge of said leg and unattached to said surface between said inboard and outboard edges, whereby in use, the diaphragm tends to vibrate from the said outboard edge across the space between the legs unless the diaphragm is moved by the tongue of the user against said surface, when said surface and inboard edge tend to serve as a fret effectively to shorten the diaphragm and increase the tension, thereby to vary the pitch of the sound produced by the diaphragm.

Abstract
A diaphragm type game call has at least one diaphragm mounted in a frame in such a way that the diaphragm cooperate with a part or parts of the frame to permit the tension of the diaphragm to be varied selectively, as by fixing the initial effective length of the diaphragm at the outboard edge of a leg of a U-shaped frame whereby the inboard edge serves as a fret of sorts to shorten the effective length of the diaphragm when the diaphragm is pushed against it by the tongue of the user, or by providing a fret intermediate the length of the diaphragm, or by providing one or both legs of a frame with channels into which and from which a diaphragm can be readily mounted and demounted to permit the selective tensioning of the diaphragm so mounted.

- 1. A variably tensionable diaphragm game call comprising a frame and at least one diaphragm mounted in said frame, and means associated with said frame for selectively varying the tension of said diaphragm, said frame being U-shaped, with a cross-piece connecting spaced, generally parallel leg members between which said diaphragm extends, at least one of said leg member having a surface of substantial width between respective inboard and outboard edges of said leg member, said diaphragm being mounted at said outboard edge of said leg and unattached to said surface between said inboard and outboard edges, whereby in use, the diaphragm tends to vibrate from the said outboard edge across the space between the legs unless the diaphragm is moved by the tongue of the user against said surface, when said surface and inboard edge tend to serve as a fret effectively to shorten the diaphragm and increase the tension, thereby to vary the pitch of the sound produced by the diaphragm.
- 19. A variably tensionable diaphragm game call comprising a frame and at least one diaphragm mounted in said frame, and means associated with said frame for selectively varying the tension of said diaphragm, said frame being U-shaped, with a cross-piece connecting ends of two spaced, generally parallel leg members on which ends of said diaphragm are mounted and between which said diaphragm extends, forwardly of said cross-piece and generally parallel to a forward edge of said cross-piece, said cross-piece being flexible and bowed, whereby pressure of the tongue on said cross-piece causes the cross-piece to tend to flatten, increasing the effective spacing of said legs from one another and increasing the tension in said diaphragm.
- 24. A variably tensionable diaphragm game call comprising a frame and at least one diaphragm mounted in said frame, and means associated with said frame for selectively varying the tension of said diaphragm, said frame being U-shaped, with a cross-piece connecting spaced, generally parallel, outer leg members and an intermediate finger extending generally parallel to said outer leg members and positioned to engage the diaphragm intermediate the legs when the diaphragm is moved toward the finger by the tongue of the user.

26. A variably tensionable diaphragm game call comprising a frame and at least one diaphragm mounted in said frame, and means associated with said frame for selectively varying the tension of said diaphragm, said frame being U-shaped, with a cross-piece connecting spaced, generally parallel leg members, said diaphragm being mounted on said leg members to extend between them, said leg members having outboard and inboard edges and a generally flat surface between them on at least one side, said surface being stepped intermediate its length, and diaphragms extending between said legs and mounted on said stepped portions whereby adjacent ones of said diaphragms are offset from one another by the height of said step.
