Abstract

A broadhead type arrowhead having a plurality of blades mounted on a body in which the blades each have a forward facing extension which are received in openings in a tip assembly. The tip assembly has a washer having apertures in which the blade extensions are received.

Claims

1. An arrowhead of the type having an elongated blade carrying body in which a plurality of blades are removably mounted, said body having a forward end and a back end, said body being mountable to the head end of an arrow shaft and having means for retaining blades, said retaining means compromising a forward facing tang on each of said blades, and a washer adjacent the adjacent forward end of said body, said washer having a laterally bounded receiving aperture aligned with each said tang in which each said tang is received so that the washer is angularly indexed to a position determined by the co-action of said tangs and said apertures.

2. The arrowhead of claim 1 further comprising a tip element attached to said body forwardly of said washer whereby said washer is placed between said tip element and said body.

6. The arrowhead of claim 2 wherein said tip element is formed by intersecting surfaces extending from a common vertex to define a point and widening rearwardly to define edges extending from the point rearwardly and which terminates at a rear end of the tip in a cross section shape defined by the termination point of said surfaces and said edges and said washer is shaped to have front cross section shape which substantially mates with said tip cross section shape and is so shaped to have edges which extend as a continuation of said edges of said tip to also substantially align with said blades to form a substantially continuing edge from the tip of the point to the blade.

7. The arrowhead of claim 6 wherein said continuation is substantially linear.

8. The arrowhead of claim 6 wherein said laterally bounded receiving aperture indexes said washer to align said edges of said washer with said blades.

9. The arrowhead of claim 2 wherein said tip forms a pyramid shape having three or more flat surfaces which intersect defining edges of the tip extending from common vertex at a front point to a rear termination of said tip and said washer has a peripheral shape to form edges which are substantially aligned with said edges of said tip at a front end of said washer and extend rearwardly across the thickness of said washer to be substantially aligned with said blades at a rear end of said washer to form a substantially continuing edge from the tip of the point to the blade.

10. The arrowhead of claim 9 wherein said continuation is substantially linear.

11. The arrowhead of claim 9 wherein said laterally bounded receiving aperture indexes said washer to align said edges of said washer with said blades.

3. The arrowhead of claim 3 wherein said tip element is shaped to provide a plurality of surfaces which extend from a common vertex at a front end of the tip element said surfaces widening to a rear end of the tip element and said surfaces intersect with adjacent said surfaces to define an intersecting edge extending in an axially straight line from the front to the rear of the tip and said washer has edges extending from a front to a rear of said washer which are aligned with the edges of the tip at its front end and with the blades at its rear end.

4. The arrowhead of claim 3 wherein said continuation is substantially linear.

5. The arrowhead of claims 3 wherein said laterally bounded receiving aperture indexes said washer to align said edges of said washer with said blades.
