Thanks Bob and Gray Buffalo, I learn something new everyday, however...........
After thinking about this I did a search through the US Patent Office to find out more. Fred Bear did patent a device for dispensing "poison" or an immobilizing drug to animals via a compartment built into a broadhead. His version of the pod was filed 25 November, 1968 and was awarded patent number 3,572,716.
However, on 4 December, 1962 approximately 6 years prior to Fred, MD De Lonais patented a "fluid injecting device", that dispensed an immobilizing drug or chemical into an animal via an arrow also. His was a device that held a pellet within the broadhead that ruptured upon impact, dispensing its contents. Patent number 3,066,940.
Please don't take this as an argument-Fred did patent a pod. However a similar device had aready been developed before he patented his. So, patent yes, inventor-not really.
For those that enjoy archery history, the patent website has alot of information, pretty neat to see what was thought of and patented back then. Thanks again, Bob and Gray Buffalo for sending me the search!
