Abstract
A game call having a bellows coupled to a reed for producing sound, together with a reed controller which is operable by contact with the bellows, thereby changing the pitch of the sound produced.
Description




BACKGROUND OF INVENTION




In the past, hunters have used various devices to call game, such as the ubiquitous tube call, in which air is blown through a mouthpiece and over a reed to generate sound. Other calls have used a flexible bellows or bulb attached to a tube call to eliminate the need for blowing through the mouthpiece.




While these calls have many advantages, they also have significant drawbacks.




First of all, the skill required to successfully operate the tube call is often more than is possessed by inexperienced or infrequent hunters and game callers.




Secondly, moisture from the operator's breath often condenses within the tube call, which may adversely affect the sound produced by the call.




Thirdly, the calls using bellows and bulbs have often had limited operational characteristics, owing to the lessened control that a bellows often has in comparison to a mouth-blown call.




Consequently, there exists a need for improvement in game calling methods and apparatuses.




SUMMARY OF INVENTION




It is an object of the present invention to provide an easily operated game call having pitch variation capabilities.




It is a feature of the present invention to include a reed plunger for controlling pitch.




It is an advantage of the present invention to allow for manipulation of the reed plunger in an easy to use fashion.




It is another advantage of the present invention to increase the certainty that the call will produce an appropriate sound.




It is yet another advantage of the present invention to provide for tuning of the call while in the field without the need for completely dismantling the call.




The present invention is an apparatus and method for calling game which is designed to satisfy the aforementioned needs, provide the previously stated objects, include the above-listed features and achieve the already articulated advantages. The present invention is carried out in an “error-less multi-pitch” approach in a sense that the amount of errant sounds, which often are produced by multi-pitch calls, is dramatically reduced.




Accordingly, the present invention is an apparatus and method for calling game which includes a bellows and a manually operative reed plunger disposed within an air chamber coupled to the bellows, where the reed plunger provides for variation of sound produced by permitting variably controllable reed vibration states.

DETAILED DESCRIPTION




Now referring to the drawings, wherein like numerals refer to like matter throughout, and more particularly to

FIG. 1

, there is shown an apparatus of the prior art, generally designated


100


, which includes a bellows


102


which may be any flexible cap or cover which is easily depressed but sufficiently resilient to return to an earlier shape when pressure is no longer being applied. Also shown is a call central section


104


, which is a container capable of receiving bellows


102


and an optional throat section


106


. Call central section


104


is shown having a cutaway section


110


, which reveals a reed/pitch control assembly


112


, therein. An optional sound chamber


108


is also shown. Optional throat section


106


may be made of the same material as call central section


104


, which could be any suitable material with sufficient rigidity and strength to accomplish the function of receiving bellows


102


and retaining reed/pitch control assembly


112


. Material such as plastic, composite materials, wood or metal and others all could be used. Optional sound chamber


108


can be of any suitable material, but a flexible and pliable material, such as rubber or soft plastic, similar to material used for the bellows


102


, may be preferred.




Now referring to

FIG. 2

, there is shown a detailed view of portions of the present invention, including call central section


104


after bellows


102


has been removed. Shown disposed inside of call central section


104


is reed/pitch control assembly


112


, which includes an air tube


202


and a reed


204


. Air tube


202


provides a passage for air to pass therethrough and further provides structural support for reed/pitch control assembly


112


. Reed


204


is a thin planar member which vibrates, producing sound when air passes over it. The combination of air tubes and reeds is a well-known means to provide sound in game calls. A reed plunger


210


is also shown having a top contact end


212


for cooperation with and activation by bellows


102


when bellows


102


is fully or near fully depressed. Reed plunger


210


may be a single piece of thin metal, such as copper or brass or any other suitable material which has sufficient rigidity to transfer force from the bellows


102


, to affect the vibration parameters of reed


204


by contacting reed


204


at various points thereon. Reed plunger


210


may have one or more reed contacting detents disposed thereon. First reed contacting detent


214


and second reed contacting detent


216


are shown. It should be understood that various numbers of detents may be used. It may be preferable that no detents, or only a single detent, be used if the call is designed as an elk call. However, if the call is designed as a turkey call or other type of call, then multiple detents may be preferred. Reed plunger


210


has an air tube coupling section


218


which couples to air tube


202


.




Also shown in

FIG. 2

is first screw sleeve


222


, second screw sleeve


224


, third screw sleeve


226


, and fourth screw sleeve


228


. A reed plunger limiter


230


is shown disposed through limiter hole


229


. Reed plunger limiter


230


may be a screw or other member which is adjustable, so as to limit the permissible deflection of reed plunger


210


to predetermined levels. These predetermined levels are set to prohibit unwanted pitches from being emitted by the call if the bellows


102


and reed plunger


210


are depressed further than is needed to produce the desired pitch. Reed plunger limiter


230


may be a set screw which is adjustable through limiter hole


229


.




Now referring to

FIG. 3

, there is shown a partially exploded view of the call of the present invention which includes a bellows grasping member


302


, which has a bellows grasping rim


304


, which may be inserted inside bellows


102


and cooperate with a bellows bottom rim


306


formed around the periphery of bellows


102


. Bellows grasping member


302


has an air passage hole


308


therein for permitting air from inside bellows


102


to flow to and through air tube


202


. When the bellows grasping member


302


is pulled into contact with central body rim


240


by insertion of first, second, third and fourth screws


422


,


424


,


426


and


428


, respectively into first, second, third, and fourth screw sleeves


222


,


224


,


226


, and


228


, respectively, and coupling with first, second, third, and fourth screw grasping members


322


,


324


,


326


and


328


respectively, preferably an air-tight seal forms between bellows


102


and call central section


104


. Bellows grasping member


302


also assists in limiting the maximum stroke of the bellows


102


as it is compressed during call operation, and thereby assists in limiting the range of deflections of reed plunger


210


which are permissible. The placement of the bottom


307


of bellows grasping member


302


and its air passage hole


308


with the respect to the top of the bellows can be varied to alter the stroke characteristic of the bellows


102


.




Also shown in

FIG. 3

is a side view of reed/pitch control assembly


112


, which shows a pitch adjustment screw-receiving flange


418


disposed on reed plunger


210


. Reed plunger


210


is capable of translational motion along air tube


202


and reed


204


. Translating reed plunger


210


results in different points of contact along reed


204


by detents


214


and


216


(or preferably a single detent for elk calls). This results in tuning the pitch of the call. The translation of the reed plunger


210


is accomplished by turning reed pitch adjusting screw


456


, through pitch adjusting screw hole


454


, so that reed pitch adjusting screw


456


cooperates and manipulates the pitch adjustment screw-receiving flange


418


of reed plunger


210


. Air tube


202


has an outlet end


450


with an air outlet orifice


452


therein. Optional sound chamber


108


, with its air holes therein, may be disposed over outlet end


450


of optional throat section


106


. Note the throat section


106


is optional, as is the sound chamber


108


, but in a preferred embodiment, both throat section


106


and sound chamber


108


may be particularly desirable. Also shown is a locking screw


500


disposed through a locking screw hole


502


in throat section


106


. Locking screw


500


is for securing reed/pitch control assembly


112


into the central section when air pressure therein might otherwise cause reed/pitch control assembly


112


to be forced out of throat section


106


.




In operation, the present invention accomplishes the goal of generating sounds suitable for calling game as follows: the bellows


102


is depressed a first distance, thereby creating an airflow over reed


204


and through air tube


202


. This airflow causes a vibration of the reed


204


. The pitch of the call is controlled by the point of contact of detent(s) with the reed


204


. The point of contact is adjusted with reed pitch adjusting screw


456


. The bellows


102


is further depressed, so as to engage top contact end


212


of reed plunger


210


, which is caused to move, thereby flexing and causing detent


216


to no longer contact reed


204


. This allows reed


204


to vibrate over a different length, thereby generating a different pitch as air passes over reed


204


and through air tube


202


. If the motion of reed plunger


210


is not limited by limiter


230


, then reed plunger


210


can be caused to further flex, thereby releasing detent


214


from contact with reed


204


, thereby generating a sound having yet another pitch.




In operation, the call


100


can be tuned to provide various sounds for calling game. For example, if a predetermined elk sound is desired, then that sound is analyzed to understand the variations in pitch during the duration of the call. For example a call for an elk might start with a high pitched first segment and finish with a much lower pitch second segment. If screw


456


is adjusted, detent


216


can be positioned along reed


204


so that the first pitch segment emulates a first part of a well-known sound made by a cow elk and the second segment of the call is matched in frequency to a second segment of such well known sounds made by a cow elk. Additionally, if the predetermined sound has a third segment with a third pitch, then the placement of detent


214


can be matched by screw


456


or during manufacture of reed plunger


210


. It is believed that for elk, one of the detents


214


or


216


can be omitted or in the alternative, both can be included but through use of limiter


230


the reed plunger


210


can be prohibited from causing detent


214


from disengaging for the reed


204


. Again, for example, an elk call may have a relatively strong and noticeable second lower- pitched second segment. This is accomplished by matching the desired duration of the second segment of the call to the position of the top contact end


212


within the bellows


102


. These selections of a predetermined height of top contact end


212


, height of limiter


230


and/or placement of detent(s) to produce a predetermined sound desirable for calling elk are important aspects of the method of the present invention. While particular configurations of the present invention may be well suited for elk calls, it is intended that particular other configurations of the call and uses of such other configurations for game other than elk are included within the scope of the present invention.




These well-known sounds made by a cow elk and elk fawns are referred to herein as natural elk calls. While each elk may have a unique call, they have common characteristics which are well known to hunters and designers of elk calls. The tuning in the field of the present invention and the optimizationof the parameters of this call during design and manufacture are often done by careful listening to the sound produced by an individual familiar with thesenatural elk calls. While it is possible to use sophisticated electronic sound measuring equipment, it is believed that the present invention may be readily manufactured without such equipment, if an individual who is familiar with such natural elk calls assists in the process.




It is thought that the method and apparatus of the present invention will be understood from the foregoing description and that it will be apparent that various changes may be made in the form, construct steps and arrangement of the parts and steps thereof, without departing from the spirit and scope of the invention, or sacrificing all of their material advantages. The form herein described is merely a preferred exemplary embodiment thereof.
