Multiple pitch animal call
First Claim
1. A multiple pitch animal call comprising:
- an elongated casing;
multiple airways of differing longitudinal widths spaced longitudinally apart along said casing, each airway extending from side-to-side through the casing from a mouthpiece opening on one side of the casing to an opposed sound-emitting opening on the opposite side of the casing; and
a vibratory elastic band extending longitudinally through said casing, a portion of said elastic band being stretched across the width of each airway at a position intermediate said mouthpiece and sound-emitting openings so that air blown into one of the mouthpiece openings passes through its airway above and below the portion of elastic band stretched thereacross to vibrate said portion causing a sound to be emitted from the sound-emitting opening, a different pitched sound being produced by each airway.

Abstract
A simplified combination animal call has a casing divided into identical upper and lower half sections held together by a securing elastic band. Symmetrical channels of different widths spaced longitudinally along half sections provide airways through the casing whose openings act interchangeably as mouthpiece openings along one side of the casing and sound-emitting bells on the opposite side. Air blown through any such airway vibrates a second elastic band which spans each airway to produce an animal-like sound. Multiple airways of different widths make available several different pitch ranges at once. Changing either the size or tension of the vibratory elastic band changes the pitch that is available at each slot. Finally, the pitch produced may be dynamically varied either by changing the tension on the vibratory elastic or by compressing the mouthpiece side of the casing while the device is in use.

10. A multiple pitch animal call comprising:
-
an elongated casing divided along a longitudinal plane into longitudinally separable upper and lower sections; multiple airways spaced longitudinally apart along the casing and extending from side-to-side through the casing along said plane from a mouthpiece opening on one side of the casing to an opposite sound-emitting opening on the opposite side of the casing; a first endless elastic band extending longitudinally around one of said sections and having a portion extending longitudinally across each airway at a central position between said opposite openings so that air blown into the mouthpiece opening of one of said airways vibrates the elastic band portion extending thereacross to produce a sound from the sound-emitting opening; and a second endless elastic band extending longitudinally around both of said sections to hold the sections flexibly together; the airways having different longitudinal widths for producing a different pitch sound from each airway; each airway having a constant longitudinal width proceeding from side-to-side through the casing; each airway being defined by a channel in the upper section aligned with a channel of equal longitudinal width in the lower section; adjacent channels in each section being longitudinally separated from each other by lands having their tops in said plane; each channel being slightly relieved from said lands at said central position and becoming progressively deeper proceeding toward said opposite openings so that each airway has diminishing cross-sectional area proceeding inwardly from the openings on each side of the casing toward said central position; the first elastic band being frictionally clamped between lands for maintaining longitudinal tension in the elastic band portion extending across each airway; the lands of the upper sections being inwardly opposed to the lands of the lower section and spaced therefrom by the thickness of the first elastic band such that the sections can be rocked back and forth about the first elastic band to change the heights of the openings and control the amount of air escaping through spaces between the lands alongside the openings. - View Dependent Claims (11)
