Abstract

Abstract A calling device which has a pair of rectangular, substantially coextensive planar members, which are hinged together along corresponding edges thereof with one member being offset with respect to the other so that when the members are folded together a lip projects from the device. An endless elastic band is positioned surrounding the lip to provide a reed element positioned at the entrance into the cavity between the two members.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 269 words
A bull elk calling device comprising: a first and second rectangular, substantially coextensive, planar members; the first and second members being hingedly joined along corresponding longitudinal edges thereof, but with the first and second members being offset from one another thereby creating a lip portion of the first member extending beyond the second member at a first end of the device; the first and second members being bowed along their longitudinal axes thereof having a first bow at the first end of the device which is of small size which bow continues into a bow of larger size at a second end of the device opposite the first end; the first and second members being positioned opposing one another with their open concave sides facing one another to form a double-tapered cavity at the first end thereof sandwiched between the first and second members and extending in a direction transverse to their longitudinal axes; an endless elastic band is stretched around the first member transverse to the longitudinal axis of this member on the lip portion of the first member and is positioned at the entrance into the cavity formed between the first and second members to form a reed element; the first and second members further being constructed of resilient and flexible material such that when the two members are squeezed together, the size of the double-tapered cavity is substantially reduced beginning a the ends of the double-tapered cavity and working towards the center of the cavity and when pressure on the two members is released, the size of the double-tapered cavity is restored to its normal size.
Claim 2
Dependent Claim 269 words
A bull elk calling device comprising: a first and second rectangular, substantially coextensive, planar members; the first and second members being hingedly joined along corresponding longitudinal edges thereof, but with the first and second members being offset from one another thereby creating a lip portion of the first member extending beyond the second member at a first end of the device; the first and second members being bowed along their longitudinal axes thereof having a first bow at the first end of the device which is of small size which bow continues into a bow of larger size at a second end of the device opposite the first end; the first and second members being positioned opposing one another with their open concave sides facing one another to form a double-tapered cavity at the first end thereof sandwiched between the first and second members and extending in a direction transverse to their longitudinal axes; an endless elastic band is stretched around the first member transverse to the longitudinal axis of this member on the lip portion of the first member and is positioned at the entrance into the cavity formed between the first and second members to form a reed element; the first and second members further being constructed of resilient and flexible material such that when the two members are squeezed together, the size of the double-tapered cavity is substantially reduced beginning a the ends of the double-tapered cavity and working towards the center of the cavity and when pressure on the two members is released, the size of the double-tapered cavity is restored to its normal size.
Claim 3
Dependent Claim 96 words
A bull elk calling device according to claim 1 wherein the lip portion of the first member is bent upwardly towards the second member when the two members are facing one another, an obtuse angle being formed in the first member where the member is bent upwardly which is where the first member extends beyond the second member and wherein the endless elastic band is positioned over this obtuse angle so that a portion of the endless elastic band is disposed within the double-tapered cavity and the reed element formed thereby has a corresponding obtuse angle.
