Abstract
A hand-operated game call having a two-diaphragm sound chamber, a collapsible generally tubular bellows extending from one end of the chamber with a weight on the end of the bellows and a hollow handle on the other end of the chamber. The call is held by the handle and moved to collapse the bellows thereby forcing air through the sound chamber to produce a sound simulating the call of a wild turkey. Different turkey calls may be simulated depending upon how the bellows is collapsed.
Claims25
A game call including a sound chamber, a handle joining the sound chamber and having a horn in communication with the sound chamber, a bellows, means joining the bellows and the sound chamber to force air through the sound chamber upon collapse and extension of the bellows, a weight secured to the bellows away from the sound chamber to facilitate collapse of the bellows upon movement of the handle, the sound chamber including an interior volume, a first wall with an opening therein communicating with the bellows and a second wall spaced from said first wall and having an opening therein communicating with the horn, a first flexible diaphragm normally closing said first opening and a second flexible diaphragm normally closing said second opening, each diaphragm including a taut edge flexible to permit movement of air into and out of the sound chamber upon movement of the bellows.
A call including a sound chamber having means for the passage of air and an air source attached to the chamber, said passage means including a first wall portion having an opening communicating the chamber with the source and a second wall portion spaced from the first wall portion and having an opening therein, a flexible vibratory diaphragm stretched across said first walls opening and having a free edge normally resting on an edge of the first wall opening to close the opening, a second vibratory diaphragm stretched across the second wall opening and including a free edge resting on an edge of such second wall opening to normally close such opening, said air source including means for forcing air through the chamber via said passage means and past both diaphragms, whereby air moved by the source through the sound chamber and past the diaphragms vibrates both diaphragms at said edges to produce a reverberant two-toned call.
A game call comprising a handle including a horn, a sound generating member at one end of the handle including a two-diaphragm sound chamber with a first flexible diaphragm normally closing an aperture in a wall portion located between the bellows and the chamber and a second flexible diaphragm normally closing an aperture in a wall portion located between the chamber and the horn, a bellows secured to the sound generating member and extending away from the handle, and a weight at the end of the bellows away from the handle, said bellows comprising a generally tubular-shaped length of resilient self-restoring material tightly joined to the sound generating member and to the weight so that movement of the weight with respect to the sound generating member forces air through the member, said bellows being asymetrical on opposite sides thereof to facilitate rapid return to an expanded condition following a collapse.
