In the illustrated preferred embodiment, the broadhead point of the invention, shown generally at 10, includes a forward leading small penetrating tip portion, shown generally at 12 and a trailing, larger, cutting blade portion shown generally at 14.
Penetrating tip 12 comprises fixed blades 18 with a common leading point 22. The blades 18 extend rearwardly and outwardly from the point 22 and are affixed to and project from a ferrule 26.
Ferrule 26 is cone-shaped and is flared outwardly from a small end 28 to a leading shoulder 30. Leading shoulder 30 extends outwardly and rearwardly from ferrule 26 to engage a trailing shoulder 32. Trailing shoulder 32 extends rearwardly and inwardly from shoulder 30 to engage a sleeve 34.
Multiple larger cutting blades 40 are fixed to and project equi-distantly from around sleeve 34. The rearwardly extending cutting edges of the blades 40 project outwardly to a greater extent than the smaller fixed penetrating blades 18 project from ferrule 26.
Sleeve 34 is threaded, using threaded shaft 48, into or is otherwise conventionally attached to the end 42 of an arrow shaft 44. The opposite end 46 of arrow shaft 44 has a nock 50 and conventional multiple vanes 52 that will impart rotation to the arrow during flight.
As shown best in
The air shown by arrows 60, in flowing over shoulder 30 to outside of fixed cutting blades 40 creates an area 70 of reduced air pressure in advance of the traveling fixed cutting blades 40. The reduced pressure of area 70 allows the larger fixed vanes to “draft” behind the top 12 and shoulder 30. This reduces the air resistance otherwise encountered by the rotating fixed cutting blades and further results in increased arrow velocity and stability.
Although a preferred embodiment of our invention has been herein described, it is to be understood that the present disclosure is by way of example and that variations are possible without departing from the subject matter coming within the scope of the following claims, which subject matter we regard as our invention.
