Abstract

A hunting arrow comprises a shaft, a tip end, fletching, and a nock having a hollow cavity with arrow locating structure disposed therein. The arrow locating structure includes a normally open electrical circuit having a power source, a time delay, a device for producing an audible signal upon expiration of the time delay countdown, and a switch adapted to close the electrical circuit extending from inside the cavity to the outer side of the nock. Upon actuation of the switch the time delay starts its countdown and upon expiration of such countdown the device for producing an audible signal is energized whereby an audible signal pinpoints the location of the arrow.

Claims

1. A hunting arrow including a nock having a hollow cavity with arrow locating means disposed therein, the arrow locating means including a normally open electrical circuit having a power source, time delay means, means for producing an audible signal upon expiration of the time delay countdown, and switch means adapted to close the electrical circuit extending from inside the cavity to the outer side of the nock whereby upon actuation of the switch means the time delay means starts its countdown and upon expiration thereof the means for producing an audible signal is energized whereby an audible signal pinpoints the location of the arrow.

2. A hunting arrow as in claim 1 wherein the means for producing an audible signal comprises a buzzer.

3. A hunting arrow as in claim 2 wherein the buzzer extends through the nock to the outer side thereof.

4. A hunting arrow as in claim 1 wherein the nock comprises two pieces with a threaded connection therebetween for providing access to the hollow cavity.

5. A hunting arrow as in claim 1 wherein the arrow locating means includes visual indicator means connected to be energized when the switch means is actuated to thereby indicate the time delay means has started its countdown.

6. A hunting arrow as in claim 5 wherein the visual indicator means comprises an L.E.D.

7. A hunting arrow as in claim 1 wherein the power source is a 4.5 volt battery.

8. A hunting arrow as in claim 1 wherein the switch means is a single pole, single throw on/off pushbutton.
