Hunting broadhead arrow
First Claim
1. A hunting broad arrow comprising hollow body means, a plurality of circumferentially spaced longitudinally extending slots provided in the body means and extending through the sidewall thereof, normally retracted independent blade means disposed in each slot and having one edge open to the interior of the hollow body means, shaft means slidably disposed in the hollow body and having one end extending axially outwardly therefrom, point means provided on the outwardly extending end of the shaft means, plunger means provided on the opposite end of the shaft means and slidably disposed within the interior of the hollow body means, retaining means disposed on the hollow body for retaining the blade means in the normal retracted position thereof during flight of the arrow, the plunger means being responsive to movement of the point means in one direction for overcoming the force of the yieldable means for moving the blade means radially outwardly to provide an increased cutting diameter for the arrow upon impact thereof with an object.

Abstract
A hunting broadhead arrow comprising a hollow body or ferrule having a plurality of circumferentially spaced slots extending through the sidewall thereof for receiving a flat substantially triangular shaped blade member in each of the slots. The shank of the point member of the arrowhead extends slidably into the interior of the body and carries a plunger member in the inner end thereof. Each blade is retained in a normal contracted or retracted position with respect to the body by suitable snap ring members, and each blade is provided with a recess on the inner edge thereof for engagement with the outer periphery of the plunger member in the retracted position of the blades. Upon impact of the arrowhead, the point member is moved in a direction toward the body for moving the plunger member rearwardly within the body whereby the trailing ends of the blades are moved radially outwardly to an extending position for the blades, thus increasing the cutting diameter of the blade upon impact to increase the efficiency of the arrowhead.
