Transmitter attachment for hunting arrows
First Claim
1. A transmitter attachment for a hunting arrow, the arrow of the type having a shaft and removable arrowhead, comprising:
- a hollow tubular member having a first and second ends;
said first ends having means for removable connection to an arrowhead;
said second end having means for removable connection to an arrow shaft;
transmitting means mounted within said tubular member for emitting a radio frequency signal;
a battery journaled within said tubular member for powering said transmitting means;
inertia-activation switch means operably mounted within said tubular member electrically connected between said battery and said transmitting means and operable between first and second positions, said first position electrically connecting said battery and transmitting means to operate the same, and said second position electrically disconnecting said battery and transmitting means;
said inertia-activation switch being operably mounted such that a dynamic force of predetermined magnitude directed longitudinally in a first direction along said hollow tubular member will move said switch to said first position, and a dynamic force of predetermined magnitude directed longitudinally in a second direction along said hollow tubular member will move said switch to said second position; and
said inertia-activation switch being adapted to remain in either said first or said second positions in the absence of said dynamic forces.

Abstract
A transmitter attachment for hunting arrows includes a hollow tubular member which is removably mounted between the arrowhead and shaft of a conventional hunting arrow. The tubular member has a transmitter mounted in one end, and a battery slidably mounted between a pair of spring contacts in the other end. The battery is mounted so as to slide forward into electrical contact with a coil spring, which closes an electrical circuit to energize the transmitter, when the arrow hits the target or the ground. Thus, the combination of battery and contacts forms a type of inertia switch. A directional receiver is utilized to locate the arrow. The transmitter is deactivated by tapping the nock-end of the arrow against the ground--which slides the battery out of contact with the coil spring.

5. In combination:
-
a conventional arrow of the type having a shaft portion and an arrowhead portion, the shaft portion having a threaded forward end and the arrowhead portion having a threaded rearward end, the threaded ends of said shaft and arrowhead being adapted for selective securement together; and a transmitter attachment having a threaded forward end and a threaded rearward end adapted for selective attachment interposed between said shaft and arrowhead; said transmitter attachment including; a hollow tubular member having first and second ends; a transmitting means mounted within said tubular member for emitting a radio frequency signal; a battery journaled within said tubular member for powering said transmitting means; and inertia-activation switch means operably mounted within said tubular member, electrically connected between said battery and said transmitting means and operable between first and second positions, said first position electrically connecting said battery and transmitting means to operate the same, and said second position electrically disconnecting said battery and transmitting means; said inertia-activation switch being operably mounted such that a rearwardly-directed dynamic force of predetermined magnitude on said arrow will move said switch to said first position, and a forwardly-directed dynamic force of predetermined magnitude on said arrow will move said switch to said second position; and said inertia-activation switch being adapted to remain in either said first or second positions in the absence of said dynamic forces.
