Abstract

An expandable blade broadhead has a plurality of blades pivotally mounted on a circular ring. The ring is retained between a cap mounted on a stud extending from the front end of a ferrule, and the ferrule. A hardened steel tip is slidably mounted in a bore in the cap, and is formed with a rearwardly facing cam surface. The blades are normally held retracted in slots in the ferrule body and cap, and the tip is normally held is an extended position. When the broadhead impacts a target the tip is forced rearwardly forcing the cam surface against the blades pivoting them out of the slots to a rearwardly inclined position. To facilitate extraction the blades may pivot freely to a forwardly inclined position and the rear edges of the blades are sharpened.

Claims

1. A hunting broadhead comprising:

(a) a cylindrical ferrule body of a first diameter said body having means at one end for mounting said body to an arrow shaft and a reduced diameter neck extending forwardly from the other end of said body and defining at its junction with said body a circular shoulder,

(b) a diametrical slot in said body extending from the forward end of said neck rearwardly into said body,

(c) a pair of elongated blades having cutting edges on both long sides positioned in said slot in a retracted position, with the forward ends of said blades positioned forwardly of said shoulder, the forward ends of said blades each having a radially inwardly and rearwardly inclined leading edge,

(d) a ring positioned on said shoulder about said neck and extending through the forward ends of said blades radially outwardly of said inclined edges whereby said blades may pivot about said ring both forwardly and rearwardly of said ring,

(e) a cap having an internal bore positioned over and secured to said neck to hold said ring against said shoulder, said cap having a pair of slots aligned with said diametrical slot,

(f) a central bore extending through said cap and neck and into said body along the longitudinal central axis thereof,

(g) a plunger having a leading penetrating top and a rearwardly extending shaft of reduced lateral dimension relative to said top, said shaft having a tapered rear end, said shaft being slidably positioned in said bore with said tapered rear end normally in contact with or ahead of the leading edges of said blades,

(h) wereby, when said broadhead is in flight said blades are normally in said retracted position thus reducing wind resistance and planeing and upon impact said plunger is driven rearwardly in said bore and the tapered rear end of said shaft pushes against the inclined leading edges of said blades to pivot said blades outwardly of said slot to a rearwardly inclined position with the rear end behind the ring to increase cutting width of said broadhead, and said blades may pivot to a forwardly directed position with the rear end of the blades in front of the ring upon rearward extraction.
